[QUOTE=Mort and Charon;32380224]And I'm studying 4 sciences for A Level (AS), Biology, Chemistry, Physics and Geology. To be honest Physics hasn't been as bad as I thought it would be, not liking chemistry a huge amount though.[/QUOTE]
which exam boards are you sitting?
Physics, but who cares
What do you get if you cross an Elephant with a Rhino? [sp]'ell-if-i-no[/sp]
What do you get if you cross an elephant with a mosquito? [sp]||Elephant||*||Mosquito|| * sin(Ɵ)[/sp]
What do you get if you cross a mosquito with a rock climber? [sp]Nothing, you can't cross a vector with a scaler[/sp]
Maths/physics double degree gets me all the bitches. Takes the same amount of time as a degree in just one.
It's gonna take me an extra semester for the math of my physics/math double major but most of that's due to my having transferred. Fucked shit up.
Anyone here familiar with the IB course program?
Just asking out of curiosity.
[QUOTE=mike;32380560]which exam boards are you sitting?[/QUOTE]
AQA for Physics, Chemistry and Biology, and WJEC (a welsh one) for Geology, since apparently it is highly regarded by Universities.
Accursed gyroscopes, what are the general solutions to their equations of motion?
Hooray! Our new microwave is a decent Faraday cage. If you put a mobile phone in our last microwave and called it it'd connect. The new one won't connect a call if the door is closed.
I guess that's a good way to tell that I'm a physics student! My first order of business (well, second actually: hot chocolate came first) was to determine if my microwave was a decent Faraday cage.

Wow, this can change a lot of things in the future...
Jesus Motherfuck, holy balls.
Probably just a measuring error, though...
the margin of error was only 10 nanoseconds
I will just wait to see if the results can be replicated before making a big fuss over it either way.

They said they repeated it and repeated it, hoping they'd made some trivial error, and they couldn't find any.
Also I never got a fucking answer to my question.
Polarisation bitches. In terms of a particle model of light, not wave model. Explain that shit.
Isn't it possible that we just haven't measured the maximum speed of light properly yet? We are measuring it in a vacuum, but at the scale at which we're measuring the speed, all kinds of additional forces can affect the light speed. At this scale we're also dealing with all kinds of (unknown) quantum effects.

No, it said they reviewed their calculations over and over again, they still could have measured it wrong to begin with.

I doubt that, with the relevancy light has, the science community would be content with simple measurements. It was found out with equations by that guy who found EM waves were light,

Engineering student master race. We'll be reading physics the next term but it's not going to be much.
However we're going to have a shit ton of math classes during my five years here.
It's Computer Engineering :v:

What are you people doing?
[editline]24th September 2011[/editline]
Are you going to do a MSc, in that case, which field/subject?
[editline]24th September 2011[/editline]
I really fucking want to do my masters within Systems Biology, that really would be a dream come true. Still got 3 years before I get there though :v:
PhD master race ofc but I dunno what subject I want to specialize in. I really enjoy relativity so possibly cosmology or astrophysics or whatever the fuck they're calling it now.
Hey, the Doppler effect only happens for waves with constant speed, right? Speed that doesn't depend on the emitter's speed.

Huh.[/QUOTE]
That length of the coastline one is dumb.
It would be the exact same for the length (or almost any other property) of [i]anything[/i].
Of course you can't get exact measurements.
Well, yeah, that one they messed up. I really found the bicycle one strange.

Fractals, motherfucker!
Although in reality you'd get down to the Planck length and you couldn't go any further so you probably COULD measure it.
Would an elevator to space work?
Depends if it has enough floors

I doubt you'd even get there since the boundary would have to be defined by atoms.
Anyway, tides are constantly changing.
But so are [i]many many many[/i] other things. Everything changes
The fact that they picked the coastline and pretended it was some one-in-a-million unsolvable question really annoys me.
They didn't have the general solutions to the equations of motion on a gyroscope. That's a pretty important unsolved problem. Or the general solutions to the Navier-Stokes equations.
