Right around the corner. Already have VR threads, but non VR stuff will be talked about too.

There are tons of VR shows.  

If we were to get videos, when would we get them?

No clue.

There's some portal for videos I've used before but I'm not sure when it's updated.

The main site has a vault, but nothing set up for the one right now.

HYPE!!!!!!!!!!!!!!

Or maybe not. I'll look keenly for any news but I'm expecting nothing that interesting.

Or.... or, maybe you can get excited about all the learning!

Or... or, maybe I can get excited about all the cool maths I've been learning in college that I need to revise for my mock next week!

Or.... or, maybe I can get some sleep! Yeah, I'll go for that one.

What kinds of maths?

I've been doing loads of calculus lately actually. Its been really fun.

In our pure modules we've been solving second order differentials and things like that using the chain rule, auxiliary equations, particular integrals, integrating factors, substitution and things like that. We've also done limits and using MacLaurin's theorem to work out limits of integrals of trig and natural logs functions and stuff. Lots of integration basically!

And in mechanics we've been looking at forming equations to model the motion of objects with variable mass - like rockets or snowballs or hailstones - so forming crazy DEs and then using pure methods to solve it. Also we've just looked at finding moments of inertia of various shapes by considering splitting them up into smaller shapes and integrating (like splitting a sphere up into an infinite amount of infinitely thin discs and using integration to add up the MI of each disc). We also looked at using DEs to model the motions of particles using polar co-ordinates and we're about to look at using DEs to model forced and damped harmonic motion.

So many differential equations! But I'm loving it!

I learned a lot of that in ODE.  
I'm always blown away by the math stuff you're learning.  

I had to learn a lot of Calculus on my own.

Oh god I couldn't imagine learning most of that stuff without my teacher. It would be ridiculous. I've been blown away by some of the math stuff I'm learning to be honest. The motion of variable mass questions in particular are just ridiculous sometimes.

[Xevross]

This is pretty of topic now.. but oh well! Here's an example question of the variable mass stuff:

A spherical hailstone falls under gravity through still air. As it falls, it acquires moisture from the air, causing it to increase in mass. You may assume that the hailstone remains spherical throughout the motion and that no external forces other than gravity act to affect the motion. At time t seconds, the radius of the hailstone is r, its mass is m, and the radius, r, is increasing at a rate lr, where l is a positive constant. The density of the hailstone is p , a positive constant. Find velocity v as a function of time t.

v = g/3l + (u - g/3l)e^-3lt            is the answer (u is initial velocity)

I actually ended up skipping a math class.  
Then I took a semester off from math.  
Then I took ODE, which was pretty much

This stuff.  all the orders above second order are solved the same way as second order pretty much.  
Then I took another semester off.
And now I'm taking Linear Algebra.  Which is pretty easy.  

A spherical hailstone falls under gravity through still air. As it falls, it acquires moisture from the air, causing it to increase in mass. You may assume that the hailstone remains spherical throughout the motion and that no external forces other than gravity act to affect the motion.

v = g/3l + (u - g/3l)e^-3lt            is the answer (u is initial velocity)

Yeah, I don't know what happened between the question and the answer.
