The problem with learning mathematics using software, is computers will always do what you ask, which may not always be what you want. If you don't understand the math, how can you be sure you are asking the computer the solve the right thing?
As i said depends on the legal system where you live. I can only say how it works in denmark. Here he would be prosecuted if someone files charges against him, which would be either the univeristy or the students whose signature he falsified.
Depending on the laws in your country, suspension might be the least of his troubles. Where i am from, falsifying a signature is fraud, and can be punished with prison.
to put things in perspective, i brought a new laptop this summer with an i5 (2.6 GHz) 6 Gb RAM and AMD 7600 graphics card for around 1400$. But this was in Denmark were the prices generally are around 15% higher than in America.
Hi there.
I'm not quite sure where you see this discrepancy. The picture you linked from wikipedia, clearly shows visible light is in the range of 0.5 μm, which is the same as 500nm.
