If anyone has any more like this, I would be very appreciative.

European versus american science. go!

Can anyone help me, I can't figure our how to solve equations in <span class="math"> \mathbb{Z}_{6} [/spoiler]

Hi /sci/, I have trouble with this question on momentum:

In nuclear reactors, the neutrons produced have to be slowed down to make them more effective in the reactor core. To do this, they are allowed to collide with carbon atoms in graphite blocks called moderators untill they have slowed down considerably. Assuming that the mass of a neutron is 1 unit and that the mass of a carbon atom is 12 units, find the ration of speed of a neutron after collision to its speed before collision with a stationary carbon atom. You may assume that each collision is perfectly elastic and "Head-on".

I know the answer is 11:13, I just don't get how you can get to it.

hi, just wondering, in the aplication for university, I saw many physicist (abb. 20%) that go into banking and finance sector. Is it easy to get into that with a physics degree?

Denizen of /wg/ here, and I would say that these are more infographic than wallpaper. I'll dump a few of my own.

Okay, first time on this board. I have a spherical thin shell and a semi spherical shell. I wanna get the inertia for each about a diameter, where the diameter of the hemispherical shell makes the system look like an umbrella being spun by the handle as the diameter.

So, my prof said the inertia for the sphere is 2/5mR^2, which I can buy. However, a peer of mine later said that the inertia of the hemisphere is the same, 2/5mR^2, which set off my bullshit detector. I think it should be 1/5mR^2, or something like that.

Oh by the way, if you include an explanation, do it in cylindrical coordinates. Spherical is too easy.

Fuck Classical Mechanics.

Can we get some science related wallpapers?
