Exams!!1

So, I have gotten back my first two exams at MIT. In Calculus, I got an 84 (74 average) and in Chemistry a 93! Apparently the "high eighties" are an A in math, but alas. I got 9 points off on this problem because I read it wrong and found the integral of something much more complicated than the actual question

I'm really glad you're doing well!

quantum chemistry.

5. Consider the 1s and 2s orbitals in a H atom.

At r = a0 the values for the wavefunctions are:
ψ1s a0 ( ,θ ,φ ) = 5.394 × 10^−4pm− 3/2
ψ 2s a0 ( ,θ ,φ ) = 1.572 × 10^−4pm− 3/2
a) (4 points) Calculate the probability of finding an electron in a 2s orbital in H in a cube
with volume 1.00x10^15 pm3 that is a distance a0 from the nucleus.

We are also doing radial probability distributions of electrons and such.

Congrats on the doing-well, I'm sure you'll continue to. :3

Saw your mom today! She fixed my glasses.

Sounds like you are doing well for a first exam period. Some people don't fare as well on their first exams. You'll get better at them!
