Heh. Maths calculator for me. Unit 1 GCSE.

 

Party on Ventrilo! :derpe:

Anyways, bored. Had to wait a long time just to talk to a consular for some assignment/project for a class.

Bored bored bored, back to BF3.

 

if headahces count as flu

also this pic covers 3 ships at once

 

Omigosh that is so cute. I'm saving it.

 

Ha, tomorrow is my last day of school for the week!

I love shortened weeks!

 

*Still prefer my TwiDash.*

:derpe:

 

This is pretty cute.

 

Omg! That is so cute.. Its like rarity is being motherly to Fluttershy. Props to the art designer for this.

 

Had sixth form tasters today! For computing, we had to program a Robosapien to do stuff. T'was disappointingly easy... And that thing kept watching me, I swear...

Anyway, with that random little story, I bid you farewell, for I must rest...

 

Night DoDo

 

It's a whole different story in actual AS-level Computing. More 'fun' and challenging. :derpe:

 

Nice for a first song, but it needs more, as the french would put it, 'umph'.

You've got the basic melody down nicely, the drums are done well, but the problem is that for the most part of the piece you have a drum beat, a foreground melody, but no third layer of music. Call me picky, but I like my music to either be really basic (which most of the time needs context, like a video or make it game bgm), or have some sort of complexity.

Otherwise, 's a good start!

 

Thank you. I'm still learning, but I shall now start on song number 2.

Side note: This was my second song ever fully made. If you guys would like to have death by music, I'll upload my horrible attempt for a year ago.

 

I thin I win at physics.
So.
Code tags, get!
Formula for conservation of energy, specifically an elastic collision:

Code:

m[sub]1[/sub]v[sub]1[/sub] + m[sub]2[/sub]v[sub]2[/sub] = m[sub]1[/sub]v[sub]1[/sub][sup]\[/sup] + m[sub]2[/sub]v[sub]2[/sub][sup]\[/sup]

Known: m1, m2, v1, v2.
Unknown v[sub]1[/sub][sup]\[/sup], v[sub]2[/sub][sup]\[/sup].

So then I isolated v[sub]2[/sub][sup]\[/sup]:

Code:

m[sub]1[/sub]v[sub]1[/sub] / m[sub]2[/sub]  + m[sub]2[/sub]v[sub]2[/sub] / m[sub]2[/sub] - m[sub]1[/sub]v[sub]1[/sub][sup]\[/sup] / m[sub]2[/sub] = v[sub]2[/sub][sup]\[/sup]

So now we can substitute it into this equation:

Code:

m[sub]1[/sub]v[sub]1[/sub][sup]2[/sup] / 2 + m[sub]2[/sub]v[sub]2[/sub][sup]2[/sup] / 2 = m[sub]1[/sub]v[sub]1[/sub][sup]\2[/sup] / 2 + m[sub]2[/sub]v[sub]2[/sub][sup]\2[/sup] / 2

And we get:

Code:

m[sub]1[/sub]v[sub]1[/sub][sup]2[/sup] / 2 + m[sub]2[/sub]v[sub]2[/sub][sup]2[/sup] / 2 = m[sub]1[/sub]v[sub]1[/sub][sup]\2[/sup] / 2 + m[sub]2[/sub](m[sub]1[/sub]v[sub]1[/sub] / m[sub]2[/sub]  + m[sub]2[/sub]v[sub]2[/sub] / m[sub]2[/sub] - m[sub]1[/sub]v[sub]1[/sub][sup]\[/sup] / m[sub]2[/sub])[sup]\2[/sup] / 2

Which simplifies to:

Code:

m[sub]1[/sub]v[sub]1[/sub][sup]2[/sup] / 2 + m[sub]2[/sub]v[sub]2[/sub][sup]2[/sup] / 2 = m[sub]1[/sub]v[sub]1[/sub][sup]\2[/sup] / 2 + m[sub]2[/sub](m[sub]1[/sub]v[sub]1[/sub] / m[sub]2[/sub]  + v[sub]2[/sub] - m[sub]1[/sub]v[sub]1[/sub][sup]\[/sup] / m[sub]2[/sub])[sup]\2[/sup] / 2

And now we can find v[sub]2[/sub][sup]\2[/sup].
I need this for a Physics Engine I am coding.

Physics.
It is the numbers.
All of the numbers.
Ya Math.
What'cha have to say to this?

 

Boo math!!

 

I'm not a fan of Physics lol.

Just say 42.

^ eeyup

In other news, I have discovered jumpstyle! I must learn it!!

 

All about the Melbourne Shuffle.

:derpe:

 

>Jumpstyle

It's nice, but I prefer shufflers.

Mostly because I can't shuffle, while jumpstyle is easy after 6 years of fencing.
