Need some help with school? You’ve come to the right place!
Welcome to the Training Hollow, where you can get help from or help others with their academics! If you can’t quite understand something you learned in school or you’re stuck on a particular question, ask away for help on this page! There’s just one pretty important rule to follow on this page:
NO ACADEMIC FRAUD!
Academic fraud means cheating on your quizzes, tests, labs, and assignments by using answer keys or by purely copying another person’s work (aka plagiarism). Please do all of your work by yourself! Even if someone gives you the step-by-step solution, do it again yourself so you can understand how the solution was reached or why something specific was done in a specific step.
To those wishing to help others, try to focus more on helping the BlogClanner reach the answer themselves 🙂 Teach them the methods or reasoning that’ll lead to the solution. Just giving them the answer might not teach them how to do similar questions in the future!
As the old saying goes,

Figured this post belonged here because I’m searching for advice on what to learn! ^^
I’ve been reading everywhere that Russian is a great language to learn if you want to immerse yourself in the literary arts. Learn from the great Russian authors, you know? I’m tempted by this, because I’m sure there’s things and meanings in the language that are untranslatable (you’d be hard-pressed not to find untranslatable things between languages, but I’m assuming there’d be more of a difference than, English and Spanish for example?).
I’m wondering if learning Russian and then exploring its literature (among exploring other things) would help me become a better author. Although, French pops up on some of those lists (of best languages to learn for the arts), and I’m learning it currently, so maybe I should just stick with it?
You can do French and Russian both!
I could – I have two other languages I want to learn alongside French and Russian, so I’m afraid it might be too much, you know? But there are plenty of people out there who have learned more than three languages, so I suppose I always could take on both if the urge to Russian kept persisting! ^^
You’re young and your brain is still fluid, so this is the best time for learning languages (and lots of other things). Whether you should try to learn French and Russian at the same time sort of depends on whether you have enough time to devote to each to do a good job. They are different enough that you are unlikely to confuse one with the other, unlike, say, Spanish and Italian. Have you read any Russian literature in translation? Do you find it engaging enough to want to make the major effort to read it in the original?
Another related question is what your educational goals are. Your bio in the BlogTeam Den says you’re a student, but it doesn’t say at what level (HS, college?). There are academic majors where having two foreign languages is a requirement.
Thank you, this was very helpful with my consideration of everything! I have read some translated Russian fairytales, but reading more translated Russian is a great idea; I’ll do that first before I decide whether I want to learn the language or not.
And I am a college student! I’ll be in my third semester this autumn. My current major is art but I may switch to writing, I’m not sure yet.

Oh, I forgot to add, may I ask you about – well, you saying that being young is the best time for languages (among other things), and I’d love to know what those other things are, what you think everyone should do while young. I grew up in a very sheltered lifestyle and most of my days were spent sitting around the house, either online or doing something like reading – I didn’t really have the opportunity to explore much further than my block. Now that I’m starting to break out of that, I’d love to be able to take what opportunities I can get!
I think it applies to all kind of skills-based learning. Being who I am, I would especially emphasize learning to read music and play an instrument, if you haven’t already done so. I’m sure you have plenty of tasks on your plate as a college student, and more than enough demands on your time, but if you do this now, you will have the skills for the rest of your life. Learn an instrument like guitar or keyboard that you can play either by yourself or with others. (I know that I am not your mentor and don’t get to give you assignments.)
That’s good to know! I used to take piano lessons a while ago but my teacher moved away and I haven’t picked it back up since, but in the back of my mind I’ve always wanted to. I also haven’t learned how to read music either. I’ll carve out the time to learn how to read it and play the piano, thank you!
I wish you all joy and success in whatever you choose to do.
Thank you so much! 🙂
Feel free to ignore or delete this question if it’s too intrusive, but I’m wondering in light of what you said above whether you were home schooled.
Thanks for making sure! I was home schooled, yes. I was taken out of school halfway through 5th grade and was home schooled throughout all of high school.
AKSHFS HOMESCHOOL BUDDIES :DDD
Homeschool buddies!!!! 😀
you should learn how to code it’s pretty painf- I mean fun. /lhj
I got a Toyhouse account recently, so I totally get you there 😛
I’m not familiar at all with Russian or French, but I do find it hard to learn more than one language at once, personally. And I don’t think of myself to be exceedingly terrible at learning languages (…Right? No? Eh, fine then. /j 😛). So I think I’d recommend sticking to one language until you’re completely comfortable with it (:
That’s just me though, you should ask Flam, they’re learning like, what, 7 languages at once 😛 /lhBuuuut of course, if you’re confident that you’d be fine with learning two at a time, definitely give it a go! It’s your choice in the end, but if you decide to do it, I hope you have fun (:Thanks for the advice! I agree with you about not learning more than one language at a time – I read a quote that went something like this: “Do you want to learn how to speak five languages? Well, learn how to speak four.” And at at first it may sound unhelpful, but you know, what it’s saying is to learn one language and stick with it, and then you’ll become fluent, rather than knowing bits and pieces of two languages or more, but anyway, I thought that quote was interesting 😛 Thanks again! ^^ /gen
That’s a fun quote 😛 And no problem! (:
I have been summonedIndeed you have 😉:00Asian languages are difficult to learn, as there are little similarities to European languages, but stick with it and it means you’ll know something your friends don’t 😈😝🤣
Can someone explain me how you can animate? I wanna try it but idk how. Also, good websites to do it with? I can’t download anything.
I only started learning how to animate about a month ago for my art project, but I think Animaker is a good site for becoming more familiar with animating because it’s free and easy to use. If you’re OK with the limited character designs, I recommend Animaker.
For how to animate, if you watch the tutorial*, using the programme will be pretty straightforward.
Canva’s also a nice app for making videos, but I haven’t tried animating with it yet.
Both apps are available on the web and you don’t need to download anything. Have fun. :]

Thank you! This was very helpful!
Could anyone give me a proof of why kinetic energy is conserved when two objects of different masses collide elastically? I’ve looked for this in Perplexity.ai, but there was a mistake in the answer the programme gave me.
An update on my last comment:
I tried proving this myself out of all the wrong answers Perplexity gave me, and here’s what I got.
( I’m not sure if everything here is true, but here goes: )
Let’s say that the mass of the two objects are m and M. The velocity of each object before the collision are u and U, and each object’s velocity after the collision are v and V.
(WLOG u > U, V > v)
STEP 1 Elastic Collision (e = 1) ⇒ The total kinetic energy is conserved.
Since the momentum is conserved due to there being no outside forces,
m*u + M*U = m*v + M*V
⇔ m*v – m*u = M*U – M*V
⇔> m(v – u) = M(U – V)
And since e = {(V – v) / (u – U)} = 1
⇔ V – v = u – U
⇔ v + u = V + U
Here, let’s say that v + u = V + U = x
m(v – u) = M(U – V) ⇒ m(v – u)*x = M(U – V)*x
So,
m(v – u)(v + u) = M(U – V)(V + U)
⇔ m(v^2 – u^2) = M(U^2 – V^2)
⇔ m*v^2 – m*u^2 = M*U^2 – M*V^2
⇔ m*u^2 + M*U^2 = m*v^2 + M*V^2
⇔ 1/2*m*u^2 + 1/2*M*U^2 = 1/2*m*v^2 + 1/2*M*V^2
QED
STEP 2 Elastic Collision (e = 1) ⇐ The total kinetic energy is conserved.
Since we know that the total kinetic energy is conserved,
1/2*m*u^2 + 1/2*M*U^2 = 1/2*m*v^2 + 1/2*M*V^2
⇔ m*u^2 + M*U^2 = m*v^2 + M*V^2
⇔ m*v^2 – m*u^2 = M*U^2 – M*V^2
⇔ m(v^2 – u^2) = M(U^2 – V^2)
⇔ m(v – u)(v + u) = M(U – V)(V + U)
And since the momentum is conserved,
m*u + M*U = m*v + M*V
⇔ m*v – m*u = M*U – M*V
⇔ m(v – u) = M(U – V)
Here, let’s say that m(v – u) = M(U – V) = y
The velocity before and after a collision cannot be the same, so
v ≠ u, V ≠ U
⇔ v – u ≠ 0, U – V ≠ 0
And, the mass of an existing object cannot be 0. Because of this, we can say that
m(v – u) = M(U – V) = y ≠ 0
m(v – u)(v + u) = M(U – V)(V + U)
⇔ y(v + u) = y(V + U)
⇔ v + u = V + U (∵ y ≠ 0 )
⇔ u – U = V – v
In a scenario where two objects collide, they cannot be the same speed before the collision. (Otherwise, the collision cannot happen.)
Which means u ≠ U
⇔ u – U ≠ 0
u – U = V – v, u – U ≠ 0
⇔ {(V – v) / (u – U)} = e = 1
QED
∴ The proposition Elastic Collision (e = 1) ⇔ The total kinetic energy is conserved. is true.
Could anyone tell me if I made a mistake?
I… still can’t believe you’re in the same grade as me, I failed to comprehend any of that 😛 Now you can imagine how absurd my school is, where the brain of a kid like me is worshipped 😭
Being unable to understand this is natural for Korean secondary school kids in year 2. These principles are from Physics 2, which is 4 years ahead of what we’re currently learning.
You don’t need to be so hard on yourself. I’m only able to write these weird equation because of prior learning. I think you’re very thoughtful and clever, and you have many good traits. As for your school, it’s quite normal compared to mine.
The exam averages are below 75.-_-Haha thank you, I didn’t know it was that ahead of our grade 😛
Bro our school exam average is 60 or something 😭I- I never knew middle schools in other regions (Assuming you live outside my district) gave such hard exams.
Data says that my region is one of the least smartest in Korea. Probably why the exams are relatively easy.(Hi Shadedheart! I’ve deleted the image you used for your profile picture on the blog because we don’t feel comfortable allowing some of the imagery in it on the blog. Please use something else ^^)
I apologise if my former profile picture contained unsuitable imagery. I promise that I didn’t have any bad intentions about that image. I’ll try to be more careful when uploading public content from now on.
Thank you for understanding ^^
Srry, I can’t lol😛
may I ask why you need to prove it……?
from what I learnt, the definition of elastic collision includes the fact that the total kinetic energy remains unchanged……
okay i did a bit of reading so what i got is that e=1 is another way of defining the elastic collision (with e being sth invented for the sake of defining it), which is why if you solve equations (a)m1v1+m2v2=m1v1’+m2v2′ (b)v1-v2=v2′-v1′ OR (a’)m1v1+m2v2=m1v1’+m2v2′ (b’)1/2*(m1*v1^2)+1/2*(m2*v2^2)=1/2*(m1*v1’^2)+1/2*(m2*v2^2) you’ll get the same results of v1′ and v2′
what we learn in high school as far as I know (as your average middle schooler learning high school stuff) is the latter
correct me if im wrong <3
Looks like that was a mistake on my part. I know it’s not exactly important, but I was curious about why elastic collision had 2 definitions, and if they were necessary and sufficient to each other .
(And I accidentally said that what I wanted to prove was Elastic Collision ⇔ ΣEk = constant. instead of e = 1 ⇔ ΣEk = constant.
Sorry for making that so confusing.)
I couldn’t find any good sources, so that’s why I did that bunch of maths, and this was what I got.
oh right–I myself, as said, only learnt the constant bit, so i cannot help with that from now😢
(and yes for me I use equations to get the v1′ and v2′ all the time too)
Yes, this proof I made doesn’t help solve typical physics problems. Like you, I solve simultaneous equations to get the value I don’t know when solving problems.
forgive me but im curious what level of education ur receiving 😛
Currently, I’m learning high school Physics 2 (4 years ahead of my school grade) through online classes. I think that’s similar to AP Physics in America.
(I’m not American either 😛 )
& I think we’re learning at approx the same pace actually lol
(:
For your previous comment, I left a reply. It’s being kept in moderation because of content checking, I think?
ah yes I replied to it
This is one of the reasons I miss Eggsnake. He would certainly have understood this. I don’t.
For real 😛
why is that so real 😛
Oh my gosh I did not understand a word of that😭 You’re so smart!!
OK, this comment is quite confusing, so I edited it a little to help people understand this.
*It’s fine if you don’t understand it still, I only got rid of some word problems, and this proof I made requires a bit of maths and physics knowledge.
Let’s say that the mass of the two objects are m and M. The velocity of each object before the collision are u and U, and each object’s velocity after the collision are v and V. (WLOG u > U, V > v)
● p ⇒ q : proposition p is a sufficient condition for proposition q. (p implies q)
● p ⇐ q : p is a sufficient condition for q. (q implies p)
● p ⇔ q : p and q are equivalent. (p is true if and only if q is true. / p iff q)
● e : coefficient of restitution
: ratio of the relative velocity of separation after collision to the relative velocity of approach before collision.
In this case, e = {(V – v) / (u – U)}
● Ek : kinetic energy
STEP 1: e = 1 ⇒ The total kinetic energy is conserved. (ΣEk = constant)
Since the momentum is conserved due to there being no outside forces,
m*u + M*U = m*v + M*V
⇔ m*v – m*u = M*U – M*V
⇔ m(v – u) = M(U – V)
*The same equation can also be derived by formulating that the amount of impulse is the same.
And since e = {(V – v) / (u – U)} = 1
⇔ V – v = u – U
⇔ v + u = V + U
m(v – u) = M(U – V), v + u = V + U
⇒ m(v – u)(v + u) = M(U – V)(V + U)
⇔ m(v^2 – u^2) = M(U^2 – V^2)
⇔ m*v^2 – m*u^2 = M*U^2 – M*V^2
⇔ m*u^2 + M*U^2 = m*v^2 + M*V^2
⇔ 1/2*m*u^2 + 1/2*M*U^2 = 1/2*m*v^2 + 1/2*M*V^2
⇔ (total kinetic energy before collision) = (total kinetic energy after collision)
□
STEP 2: e = 1 ⇐ The total kinetic energy is conserved. (ΣEk = constant)
Since we know that the total kinetic energy is conserved,
1/2*m*u^2 + 1/2*M*U^2 = 1/2*m*v^2 + 1/2*M*V^2
⇔ m*u^2 + M*U^2 = m*v^2 + M*V^2
⇔ m*v^2 – m*u^2 = M*U^2 – M*V^2
⇔ m(v^2 – u^2) = M(U^2 – V^2)
⇔ m(v – u)(v + u) = M(U – V)(U + V)
And since the momentum is conserved,
m*u + M*U = m*v + M*V
⇔ m*v – m*u = M*U – M*V
⇔ m(v – u) = M(U – V)
*The same equation can also be derived by formulating that the amount of impulse is the same.
The velocity before and after a collision cannot be the same, so
v ≠ u, V ≠ U⇔ v – u ≠ 0, U – V ≠ 0
And, the mass of an existing object cannot be 0.
⇔ m ≠ 0, M ≠ 0
m ≠ 0, M ≠ 0, v – u ≠ 0, U – V ≠ 0
⇔ m(v – u) = M(U – V) ≠ 0
m(v – u)(v + u) = M(U – V)(U + V), m(v – u) = M(U – V) ≠ 0
⇒ v + u = V + U
⇔ u – U = V – v
In a scenario where two objects collide, they cannot be the same speed before the collision. (Otherwise, the collision cannot happen.)
Which means u ≠ U⇔ u – U ≠ 0
u – U = V – v, u – U ≠ 0
⇒ {(V – v) / (u – U)} = e = 1
□
∴ The proposition e = 1 ⇔ The total kinetic energy is conserved. (Σ = constant) is true.
*∴ The proposition e = 1 ⇔ The total kinetic energy is conserved. (ΣEk = constant) is true.
I-I’m sorry but I didn’t understand a word of that TwT
I learnt about energy including elastic and kinetic energy in science class (IB/British, year 7/grade 6) but never anything like this. What education did you receive to learn this, if you don’t mind me asking?
(I also tried creating a bunch of answers to “Elastic Collision = The Amount Of Kinetic Energy Conserved” and quickly ruled out all my answers and saw that the question was true at the end :P)
Elastic collisions and elastic potential energy sound similar, but they are two different things. An elastic collision is a collision where the coefficient of restitution (commonly known as ‘e’) equals 1. It can also be defined as a collision in which the total kinetic energy is conserved. (the total kinetic energy before the collision = the total kinetic energy after the collision)
This concept (elastic collision) is from high school Physics 2 in the South Korean Education curriculum. I take online classes using the video communication platform Zoom, mostly because I’m preparing for TPL (The Physics League) in August, and because I’m really interested in learning physics in general.
This is somewhat irrelevant to what you’ve asked, but it’s pretty cool that you learn kinetic and potential energy in year 7/grade 6. We learn that in year 3 of secondary school (9th year of school/age 15) where I live. I learn it in school next year.
looks good to me!
So I had a question about Greek mythology…
Basically, there’s a prophecy stating that Paris would be the downfall of Troy, right??? But last I can recall, there was also a prophecy that as long as Troilus was alive, Troy would survive. So wouldn’t these prophecies almost cancel out each other??? Like, Paris could be living in Troy but as long as Troilus is alive, Troy wouldn’t fall, therefore practically nullifying the first prophecy. So how would that work???
It might just end up being a paradox, but I don’t know.
Perhaps 🙂
Well, no, not necessarily. It just means that Troy won’t fall while Troilus is alive – even if Paris died first, it wouldn’t negate the prophecy that Paris would be the city’s downfall because his choosing of Aphrodite as the fairest goddess kick-started the war. Once Troilus dies, the city can fall. There’s no time limit for Paris’ prophecy, it’s more of a “once the dominoes start to fall, there’s nothing that can be done”.
There’s a lot of prophecies within the Trojan War that aren’t covered by the Iliad because they’ve all been concluded by that point. Another one states that the Greeks could only defeat Troy once the Greek warriors got their hands on Heracles’ bow and arrows, owned at the time by Philoctetes. The entire play “Philoctetes” covers the story of Achilles’ son taking the bow back because they need it for the war.
Remember, Achilles is also fated to die at Troy, so Troy can’t fall before Achilles dies. So on and so forth. If it helps to visualize the prophecies, think of the one detailing Troy’s downfall as the centrepiece/large umbrella, under which all the smaller prophecies sit. The smaller prophecies can’t ever negate Troy’s inevitable downfall, but they will delay it until they are /all/ fulfilled
Birchy is very smart, wow :0
haha, just a Classics fan, but thanks 🙂
Thank you, Birchy!!! This makes a lot more sense now 😀 I think I’ve heard of the prophecy about Herakles’ bow before, but the one about Achilles’ death is brand new for me 😀 one of the amazing things about Greek mythology; there’s always more to discover 🙂
One of the confusing things about Greek mythology is that there are so many different versions, especially with the more well-known events, like the fall of Troy or Theseus and the minotaur, for example 😀 I’ve also heard a version where Troy would only fall if Paris managed to live to adulthood 😀 no wonder the Pythia mostly spoke in riddles; prophecies are confusing 😅
Anyways, thank you so much Birchy, the prophecies make much more sense now 😀
no problem! It’s not surprising there’s a version of the myth that stipulates Paris must live to adulthood because he only meets Helen as an adult. He’s only approached by the 3 goddesses as an adult. If he just died of illness as a child, that would not have happened yet! It’s why he’s estranged from his family – they wanted him to die as a child so he couldn’t fulfill the prophecy. It didn’t work, of course, because it never works in Greek mythology
One thing to keep in mind about the ancient Greeks is that they were never any kind of unified nation (at least not until Philip of Macedon and his son Alexander overran them all). They were a bunch of fractious cities and tribes, usually at war with each other. Each had its own heroes and favorite gods and it’s own preferred versions of their stories. There was never any central authority that imposed any kind of religious orthodoxy on them all, although there were some influential bodies like the oracle of Delphi or the Eleusinian Mysteries.
Compare the ancient Israelites, who developed a central religious authority—the priesthood of the Temple at Jerusalem—and produced a single authorized version of their scriptures.
I’m glad you answered this, Birchy, so I didn’t have to go do the research. I had never heard of the prophecy about Troilus.
no problem! I’m not super familiar with Troilus either. I imagine it’s covered in the Shakespeare play (albeit with many artistic liberties), but that’s one of the few tragedies I haven’t read haha
There’s a really detailed Wikipedia article about Troilus: https://en.wikipedia.org/wiki/Troilus
His story was in the Cypria (one of the lost poems of the Epic Cycle). According to the article, the prophecy was that Troy would not fall if Troilus lived to be 20, so Achilles had to kill him before he reached that age.
fascinating! thanks for sharing
And then Apollo assisted Paris in killing Achilles as revenge 😛 poor Troilus, though, he didn’t do anything wrong…
I believe Achilles’ death was more to do with Paris getting revenge for his brother, Hektor. As frustrating as Paris can be, my sympathies have always been with the Trojans because of how poorly the Greeks acted throughout the war, and I can never forgive Achilles for desecrating Hektor’s corpse :’)
And Achilles killed Hector in revenge for Patroclus.
hey, if Patroklos wants to run into battle wearing Achilles’ armor, he should expect Hektor to take that badly!
Yeah, what Achilles did to Hektor was horrible… the Greek myths are so brutal some times.
they are! all the Greek (and Trojan) warriors are brutal in some ways. they’re all fighting a war and they all would have owned slaves, but what’s fascinating to me is that Achilles – the ostensible hero of the Iliad – breaks even the moral code of his fellow warriors by desecrating a corpse. that even for a society as violent and bloody as the Myrmidons (those led by Achilles), Achilles is *still* shown to have overstepped the already dubious moral constraints by dragging Hektor around. I suppose what’s fascinating to me is not that Achilles is bloodthirsty and cruel, as they all are, but that he was perceived as such by his fellow warriors and everyone who spread his story
Exactly! The moral ambiguity and how tht moral ambiguity is perceived is one of the most interesting things for me to read about in Greek mythology. There are a lot of myths where there is really little or almost no repercussions at all, eg., Medea and her brother, Orphic Zagreus, etc. What I find really interesting about Achilles and some of the other mythological demigods is that despite being openly shown to have overstepped, they are still mostly portrayed as “heroes” in modern media, despite their rather immoral actions..
I’m a Medea defender not because I think she did anything right but because I support women’s rights and wrongs /j
I think your point speaks more to the problem of Classical reception, which is a very interesting topic for me! How do we perceive these figures and how does that line up with their treatment in ancient texts? And we can ask these questions with any adaptation/work of reception as recent as yesterday or as ancient as Ovid. Very fascinating!
I’m probably going to sound incredibly stupid saying this as someone who’s taken 2 years of choir, 1 year of show choir, and been in 2 musicals, but I absolutely cannot read sheet music (for both vocals and instruments, although I’m more worried about vocals) for the life of me. Our school’s choir teacher usually just teaches the parts by playing it on her piano and not having us read the music, and has never taught us the different keys or how to read music at all. I feel really, really stupid putting it out there, but I’d love any advice on how to learn to read music, as by now I’m sure that my choir teacher won’t be teaching it any time soon :’)
(osp edit – this explains it pretty well for a first time around! – https://www.youtube.com/watch?v=ZN41d7Txcq0 )
it’s not stupid to say you can’t read sheet music! (i’m going to assume you know note names when you’re singing, so i’ll skip that) i learnt how to read music just by writing it a lot when i was younger – writing out scales up and down was very helpful. my explanation won’t be the best as it’s just on a blogclan comment, but here’s a very quick explanation of how to read music
a music stave (known as a staff in the USA, so you’ll probably hear that term more. I’ve always called it a stave though, so that’s what i’m using) has 5 lines, and it’s what you use to read music. the lower the note is on the stave, the lower the note actually is. there are two commonly used clefs for different ranges – treble clef (curly looking & thing) for higher ranges, bass clef (big swoopy line with two dots after it) for lower ranges. iirc you’re either a soprano or alto, so i’ll give you an explnation of treble clef since that’s what you’ll be using:
i remember treble clef with the mnemonic every good boy deserves fruit – e, g, b, d, f. on the bottom line of the stave is e, g is on the second bottom line, b is on the third bottom line, so on so forth. for the spaces, you can use the acronym FACE – f is on the bottom space (between e and g), a is on the second bottom space (between g and b), c is on the second highest space (between b and d) and e is on the top space (between d and f)
of course, it would be a bit silly only being able to sing from low e to high f, so after you familarise yourself with the notes on the stave, there’s something else to learn! (oh joy) notes that are above or below the stave are slightly harder to read and remember, and it’s really down to practice. on the way up, after f on the top line of the stave, siting on top of the stave is a g. like on the stave, one note higher than a g is an a, which has a little line through the middle of it. this line basically says ‘pretend there’s another line on the stave here!’ it’s called a ledger line one higher than an a is a b, which has a little line underneath it, and then a high c has a line underneath the note (that’s the line the a was on) then another line through it! my explanation is horrible, and the best way to learn is just practice, so here’s a little reference picture for notes on ledger lines
after learning these notes, the best way to learn is to write the names of the notes on your sheet music – like learning a new language. first you translate it to what you know, until you can read it fluently. I did that for like 6 months before i could read music without it
(i can tell you about keys and accidentals if needed at another time, that’s a whole other thing to tackle lol)
(1/2)
the other major thing in sheet music is time signature and note durations.
let’s start with tempo. the tempo of the music tells us how fast the piece of music is going, or how fast the beat is.
this is a fast tempo – https://www.youtube.com/watch?v=qaVUswemNOE
and this is a slow tempo – https://www.youtube.com/watch?v=cNhD7utblss
note durations link to beats and tempo. the different notes and how the look tell use how many beats long the note is
a whole note is an open circle, and goes for 4 beats
a half note is an open circle with a little line next to it (the stem), and goes for 2 beats
a quarter note is a filled in circle with a stem, and goes for 1 beat
an eighth note is a filled in circle with a stem and little tail going off of that stem, and goes for half a beat
a sixteenth note is a filled in circle with a stem and two little tails going off of that stem, and goes for a quarter of a beat
two half notes go for as long as a whole note
two quarter notes go for as long as a half note
four quarter notes go for as long as a whole note
it’s just simple maths to determine how long they each go for!
there are also rests. whereas you sing/play a sound on a note, you stay silent in a rest.
there are bars which are small segments of music. they start and end with a vertical line on the music, or a bar line, and help dictate the pulse of the music
at the start of the sheet music is what’s known as a time signature. there are two numbers stacked on top of each other. the top number tells you how many notes of a certain duration are in a bar, and the bottom number tells you the duration of each note (a 1 means that each beat is one whole note long, a 2 means that each beat is a half note long, a 4 means that each beat is a quarter note long, an 8 means that each beat is a eighth note long, etc.) the most common time signature is 4/4. if we used what we’ve just learnt, then we know that there are 4 notes in a bar, and each of those notes is a quarter note.
if we refer to the maths above, though, we know that in this bar, there could also be 2 half notes, since they’re as long as 4 quarter notes. one whole note could also be used. any combination of note duration can be used, just as long as they all add up to be the same length as 4 quarter notes.
thats all i can think of off the top of my head for now! (except keys and accidentals) lmk if i explained anything poorly and/or you have any questions 🙂
(2/2)
Rhythm and *some* time signatures is one of the few things we’ve gone over in choir, actually! 😛 most of this I recognized, but I’ve always been a bit confused about the time signatures so this definitely helped a lot!! thanks again, Wosprey, I really appreciate it <33
no probs!
oh dear all my images disappeared 🙁 thats so rude wordpress
Tysm!! back in the fifth grade we learned a few songs on recorders and I vaguely remember egbdf and face, and that definitely brought back some memories haha 😛 but this helps a lot, thanks again!! I’ve heard that Duolingo teaches a music course, so I might try that and see if it helps any! :))
i did a bit of a duolingo music course! it’s surprisingly good if you don’t know how to read music, but it doesn’t really teach you any music theory. it’s a good starting ground, though!
That’s good to hear!! I did a bit of research on it
aka googling and looking at maybe the first 3 answersand apparently Duolingo’s music course is only available on phones at the moment, but thankfully I might be getting a phone soon! :))strange to see what other people use to remember the notes 😛 my piano teacher taught it to me as ‘every good boy deserves fudge and chocolate’ (to include the ledger lines)
I was always taught ‘Every green bus drives fast’ 😛
Osp did a pretty thorough job, so I don’t have much to add except that you might start by studying the sheet music for songs you already know, so that you can make the association between the notation on the page and sounds you already have in your head.
I might try that! Thanks, WhiteWhiskers! :))
idk how to read music notes so sorry I can’t help you-
also because I usually play music by ear…
same bro 😛 (dw about it tho, it’s really fine!!)
Both skills are valuable. To be a well rounded musician, learn to play both by ear and from notation.
One of the problems with WordPress, or at least WordPress as it is configured on BlogClan, is the ever-shrinking column phenomenon. Can anyone read a comment where the column is 1 character wide? I just copied the last part of Lilypaw and BIrchy’s exchange about Greek mythology and pasted into another document so I could read it.
Hehe yeah… 😛
That’s what I did too 😛
I agree with that. How about suggesting it through the feedback form?
It’s not something we can very easily fix without having to fork over some money or very niche workarounds. One possible solution that could fix things but could also cause a very big ripple in how people comment is reducing the nesting on comments and their replies, thereby preventing the comments from ever reaching that stage of illegibility. It’s currently at 10, which I believe is the default. It may be something I put up for poll or discussion after I do some more work on one of my background BlogTeam projects ^^
Thank you for clearing that out. I’m sorry if my suggestion was unreasonable.
it would be great if you could change that, those compressed comments can be a pain. also, if i may ask, what are you working on?
I can’t see if a comment is replying to another comment on a regular ereader or phone, but ya I just manage somehow-
This is a client side problem so it could just be easily fixed with a userscript. (A userscript is a bit of Javascript used to change small stuff locally).
1. Get a userscript manager (most common one is Tampermonkey, that’s the one I use). A userscript manager is just a browser extension that injects your script in.
2. Click “Create New Script” and write a script (or just use mine).
The Code
: https://justpaste.it/em5vm (go to the link and copy all of it and paste it in)3. now you can switch to a new (better) layout when you press the binoculars button (and you can go back to the old one by pressing it again) :0
maybe this can be an official feature someday?
Are you certain that Tampermonkey is 100% safe? It wants access to a lot of features of the browser.
it’s open source so as long as you make sure you trust the authors of the userscripts you use you should be fine
I know nothing about the authors. I’m asking you because you suggested it.
In this case, I’m the author of the userscript so I can vouch for it. Like I said Tampermonkey is open source so the only security risk that you could have is if you copied a random userscript without reading it and put it in. (Userscripts are written by random people like me, not Tampermonkey or any organization, so don’t use a userscript from an author you don’t trust.)
I tried this, but it didn’t change the layout and really slowed down my browser. any advice?
did you make sure to copy the code correctly? if there is a memory leak or something in the userscript it could slow down your browser so make sure the code is exact
I checked the code, and it’s exactly as you wrote it. Of course, it could be that my ancient computer simply can’t handle it. I’ll give it a try on my more modern school laptop and see if it works there.
(Also, what is a memory leak?)
In mitosis, I know that the nucleus divides in two (well technically the chromosomes do and then there are new nuclei or something but close enough), but what happens to the other organelles? Do they divide too or something else happens? And I’d also appreciate some explanation on how mitosis works because I don’t get the chromosome separating and nucleus and everything and my textbook doesn’t really explain it. Ty!
iirc, some organelles (eg. mitochondria) are dispersed between the two daughter cells and replicate later on, and some larger organelles are just replacated during mitosis (i forgot what stage)
Oh man, you just brought back a lot of memories from science class this year 😭 😭 (aka mostly just me arguing with this annoying short kid who loves to get on my nerves >:(( )
I believe some of the organelles divide with the rest of the cell, while others are replicated in the daughter cells, iirc!!
in g1 phase the irganellle replicate and then in s ohase the dna replicate and in g2 phase they check wverything so u dont get cancer 😱 and only then does mitotic phase dtart!!!
ok im on a tablet now more surface area more typing accuracy 💪💪💪💪
mitosis (or more generally cell replication) is broken into these phases
g0 = nothing is happening (it’s just living)
g1 = it starts the replication process; organelles are duplicated (except for i think the mitochondria and chloroplasts idk) and the cell expands
s = dna replication
g2 = checking everything for errors
m = mitotic; this can be either mitosis or meiosis, further broken down into four phases
cytokinesis = it divides!!!!
explanation of mitotic phases (this is for mitosis, meiosis is a little different and has double the phases):
prophase = pair together the chromosomes and stuff idk, in meiosis this is where crossing over occurs; i think the nucleus dissolves here but i dont remember 😭
metaphase = chromosomes line up at the equator of the cell
anaphase = spindle fibers pull homologous chromosomes to the poles
telophase = nucleus reforms around each of the groups of chromosomes, now there are two nuclei in the cell!
explanation of dna replication in case you need it:
1. helicase unwinds/unzips the dna (i am 99% sure there was also another enzyme involved in this but i dont remember)
2. some proteins bind to the dna to prevent them from winding/zipping again
3. dna primase puts a primer on the dna so dna polymerase can start making dna; on the leading strand, only one primer needs to be made, but on the lagging strand, several primers need to be made because polymerase can only create dna in a specific direction
4. ok here’s hopefully a better explanation: dna has to be made from 5’ to 3’, which denote what is at the end of the strand. the carbons in a 5-ring of carbons are labelled from 1’ to 5’, and on the 5’ end of the dna, there is a phosphate or hydroxyl connected to the 5’ carbon atom, while on the 3’ end of the dna there is something connected to the 3’ carbon atom. what’s important is that dna always goes from 5’ to 3’, and in this case it’s created in that direction. but dna also has to match up to itself, and with two strands of dna that are connected, the 5’ end on one strand is together with the 3’ end on the other strand. so in this case, dna polymerase READS the dna from 3’ to 5’ and WRITES the dna from 5’ to 3’. this means the leading strand is the one whose open end is 3’, so polymerase can just attach there and create dna in the same direction as helicase unzips it, which is really nice and efficient. unfortunately, the 5’ strand has to be created in the other direction, so polymerase has to attach to the primer, create in the direction opposite from the helicase, detach, and the attach at the next primer and so on. this makes a fragmented dna, each fragment is called an okazaki fragment.
5. polymerase creates a new strand of dna based on the original, or template strand. it matches up the bases to the ones on the template: A(danine) pairs with T(hymine), and C(ytosine) pairs with G(uanine). this effectively makes a new strand identical to the other template strand, thereby replicating the dna!
6. at the end of the dna strand, polymerase detaches and then goes in and replaces the primers (created by primase) with real dna. it also checks for errors and fixes them,
7. the binding proteins detach, the dna winds again and it has been replicated!!
oh my god this made me remember how much i loved biology class anyway this was just an info dump so please tell if you want a better explanation on anything!!!! hope this helps 😁
Hey there! Here’s some advice for new apprentices entering middle school!:
– Memorize your locker combination ahead of time. Make sure you have it written down somewhere at home too, in case you forget it.
– Don’t freak out if you get a bad grade. A lot of people, especially ones who got good grades in elementary school, get something like a C and panic. Take a deep breath. Its gonna be okay! Try your best, and be happy with what you achieve!
– Figure out some system of writing down and remembering things. Things to remember can include: Your laptop/charger, when things are due, requirements for assignments, and more.
-Remember that kids do not want to hurt you. When I first started sixth grade, I was terrified of eighth graders. Don’t worry. People aren’t out to get you.
– If someone is bullying you or making you uncomfortable, tell a staff member as soon as possible. Your probably sick of hearing this, but it’s important. Someone was repeatedly making me uncomfortable despite telling me to stop. I didn’t tell of them for most of the year, but when I did, they stopped! Don’t wait to report somebody.
I completely agree with these, especially the last one; it’s so important to tell adults if someone’s bullying you, even if that seems so little-kid and embarassing.
As someone who was absolutely horrified and depressed about going to middle school, I definitely agree with these statements! I assure you younguns going into 6th, middle school is highly over-exaggerated in all the movies and books; you’re almost definitely not going to get bullied or stuffed into a locker 😛
this is great advice!
This is great advice for when I go to middle school!
I guess this goes on this page since it’s about taking notes:
I’ve seen a lot of videos where people claim that taking notes in class with your non-dominant hand helps you remember what you’re learning because using your non-dominant hand uses more parts of your brain. Does anyone know whether this actually works? I’d like to give it a try, but I can barely hold a pencil with my left hand, and it seems like it would take a LOT of practice to get to the point where I can write left-handed, and I don’t want to do all that practice if it’s not actually going to help me remember what I learn. Any ideas?
I don’t think that works, it seems really hard + you’d have to focus on actually writing well enough to read instead of paying attention in class 😛
Yeah, that’s the biggest problem 😛 I have to focus so much on shaping the letters that I can’t really focus on the class
that does not work it just makes note taking a lot harder plus “using more parts of ur brian” is not the same as LEARNING MORE its just using energy on things unrelated tonlearning 😞😞 just take notes that make sense to u in a way that is comfortable for u!!!! and dont just copy what the teacher is saying, actually try to process and understand it in ur own way!!!!!! also im on vacation rn and using my tiny phone soryr if it sbad response
example my precal notes look like someone scribbled all over the paper 📝 and then ate it and spit it back out and i also ignored every single one of the guidelines on the paper for where ur supposed to write but i still passed that class… i also generally dont take notes and i just understand things in my head so that is an option too ☺️ DONY TAKE OTHER PPL ADVICE IF ITS NOT FOR U… LEARNING IS PERSONAL TO EACH PERSON!!!
Thanks Egg! I think I’m going to keep taking notes with my dominant hand in the way that has been working for me.
Whenever I write with my right hand, I’m focusing a lot more on how to write than what I should be writing down 😛 maybe try it once just to try it out?
I tried it and it takes way too much focus for me to be able to pay attention to class and write at the same time. I’m sure if I practiced it’d get easier but I really don’t feel like doing that 😛 Thanks for your input.
I’m not sure this is the right place for this, but I want to learn me a thing. Does anybody have tips for eyeliner? I don’t have a liquid one, just a pencil
try not to get a black one, instead use a brown one. I made that mistake and I will never use eyeliner again. 😛
Really? but if I use black eyeliner, it’ll match the mascara that i’d most definitely be wearing it i put in the effort for eyeliner
What makes languages sound beautiful when sung? I’m assuming there must be scientific answers to it . . . for example, many people say Italian is one of the most, if not the most, beautiful sung languages. Why is that? What structure and rules in the language – or any language – makes for a beautiful sung one? Thank you! 😀
I only know Esperanto is a terrible language to sing in except for joke songs😛 My mom and I actually made an alternate version of the Macarena but but now it’s called Korvopiedo, which is Ravenpaw in Esperanto😛
Not me Processing that cause
Corvid-crow-raven-korvo
idk, that’s what I was wondering! It’s the same with Korean I think, even though I don’t speak it.
My teacher, Lou Harrison, wrote a setting of the Buddhist “Heart Sutra” in Esperanto, La Koro Sutro:
https://www.youtube.com/watch?v=yfPtL8EJT-s
My hypothesis is rolling rs and gliding vowels, but hey… that’s just a theory. /ref
Good to know, thanks! ^^
I’m not sure I agree with the premise. I think a good composer with a sensitive ear and good singers who are native speakers of a language will produce good results, whatever the language may be.
Have you heard any Bulgarian women’s choral music?
https://www.youtube.com/watch?v=AFgzzWT3zX4
or Indian Dhrupad singing?
https://www.youtube.com/watch?v=YV4YRoxAXF0&pp=ygUNZGhydXBhZCB2b2NhbA%3D%3D
To be honest, that’s what I was thinking too! The Internet was telling me other things, but I spent yesterday morning listening to songs in as many languages as I could and if the singer had a great voice, then, well, it sounded lovely. But I was curious if there was anything nonetheless! ^^ Thanks for the music recommendations, I’ll listen to them right now!
tbh, some languages i don’t feel are really suited for singing, like how (in my totally unbiased chinese opinion) cantonese sounds better than mandarin when sung. i feel like languages are sung better when the language itself is more fluid, like in the case of cantonese and mandarin. mandarin is spoken in a very… how do i phrase this… in a very cut-off way? that doesn’t sound right. anyways, many characters end in a sharp tone of voices that really just cuts through a song when sung (even mandarin characters are stabby and sharp lmao). cantonese however, i think is more fluid, relaxed and more like japanese when listened to with the raw ear. i feel like this is why cantopop grew so popular in china, taiwan and macau, during the 90’s, even thought it came from hong kong. however mandarin has many beautiful songs too, like 一剪梅, 甜蜜蜜 (rip teresa teng) and purely in my slightly biased opinion, 喜欢你 by BEYOND, and a cover by 邓紫棋 (GEM Tang)
TERESA TENG MENTIONED!!! my dad always plays her songs <33 not meaning to butt into the conversation but i totally get what u mean!!! even between different dialects of chinese they have such different textures and rhythms
YES SOMEONE ELSE WHO KNOWS SOME OLD CHINESE MUSICIANS MY LIFE IS COMPLETE (i would assume my previous comment is moderated, even though it still says in moderation)
nah, it is in moderation bc i wanted snowy to see it, i also wanted to see what would happen to my reply 😛
oh ok, i thought is was bcuz politics n stuff
Okay, so, some random questions –
I. For does of you who have any sort of experience with AMV/PMV/MAPs and whatnot, are there certain rules you need to follow?? Eg., you can’t use certain book characters and/or songs (as per the writer/artist’s preferences)????
II. For those of you who draw digitally, what softwares/apps do you use???? Right now I’m using OpenCanvas7 but it’s extremely glitchy and either takes hours to process a slight change or just deletes all of my hard work :((
III. To any fellow authors out there; procrastination??? Writer’s block??? Help???
IV. To any published authors out there; if you published via traditional via agent, do you have any query letter tips??? Right now I’m editing my novel (trying to, at least, ^^) and I have a few agents in mind, and I have queried a few times (rejected, but that’s why I’m editing!!!! 😀 ) but still. The better the better 😛 😛
1) Northflowo made a good video on it! https://www.youtube.com/watch?v=eHtqN17v2TE
2) I use Paint Tool SAI, but I may switch to Clip Studio Paint due to my laptop not being able to run SAI! SAI is currently on an old family computer 😛 If you have a PC, you’re all good to run SAI!
3) Don’t wait until you’re motivated to write. That’s a recipe for not doing anything day after day. Show up every day, even if only for a little while. Tell yourself to only write one paragraph, or even one sentence if you’re really not feeling up to it. Even if you only write one sentence, that’s one more sentence in your story that didn’t exist prior. As for writer’s block, there’s many things you can do:
– Read. Read any book you can get your hands on. Read books in genres you enjoy, genres you didn’t think you’d ever pick up, read fiction and non fiction, read translated books. Read books praised for their goodness and read books that have gotten bad reviews! (Psst – a library’s heaven-sent if you don’t want to make a paying commitment!)
– Do nothing. Take some time off writing, fill your head up with other things. Go for a walk, watch something you like. Then go back to your story!
– Share your story with a friend or writing partner! Sometimes a good talk is all you need. That, or simply talk to yourself about it!
I don’t have any tips for the fourth one, but good luck nonetheless! 😀
Tysm Snowy!!!!!!!!!!!!!!!!!!! :DDDDDDD
You’re welcome!!! 😀
I used to have an agent, but that was eons ago, and she recruited me. My understanding is that these days if you’ve never been published you need to demonstrate to potential agents that you have a big online following—something like a blog or a podcast with a lot of subscribers.
Yeah, agents are probably going to go for people who have a bigger fan following… but who knows 😛 perhaps luck will be on my side
I. can’t help you with that sorry 🙁
II. i use ibispaint, but many people i know use procreate :3
III. i would suggest reading stories similar to yours, and if it’s fanfiction connected to a certain fandom, read fanfiction of the same fandom as yours. i would also suggest drawing ref sheets of your characters (if you’re an art person) writing out their personality and backstory, and drawing a chart of their relationship with other characters
IV. can’t help you with that either, but wow! trying to get a novel published must be hard, especially while you’re a middle school student (are you lmao? i’m going off the fact that you’re an apprentice like me. if you aren’t this is going to be awkward haha)
Ty Clover!!!!! 😀 And yes, I’m in middle school 😀
II. I use magma which is a great digital art website. You don’t need to download anything. I think it works on all devices to. I don’t have procreate cause don’t you need money or an apple product or smt
Tysm Embz!!!!
yw! 🙂 sorry I couldn’t help with the other questions!
I. no experience!!!
II. I use ibispaintx (you have to download it) and kleki! kleki is a website. it’s okay! https://kleki.com
III. uhh- just motivate yourself with- idk what- but- just- IDK XD
IV. I- uh- actually published a book once wen I was 11 (not gonna share book name because 1: it’s cringe and 2: uses my irl name) and I used KDP (an amazon company) but I recommend using Reedsy to find a good agent i guess?
