Modern Physics - The professor drew the space-time diagram thing. We derived Lorentz transformation equation for velocities and acceleration.

"In any reference frame any measurements made cannot be greater than c. The interpretation can." (something along this line.)

We talked about relativistic mass, which increases with velocity (with respect to the observer's reference frame). There's no point in talking about mass if it's not constant. There is always a reference frame, the "relativistic mass" in which is what naturally we call "mass" (in the classical sense). Apparently (even) Einstein said that "it is better to introduce NO other mass than "the rest mass" m. Instead of introducing M, it is better to mention the expression for the momentum and energy of a body in motion." (so who are we to think otherwise, haha.)

Organic Chemistry - We talked about Hecks Reaction, Suzuki's Reaction and Alkene Metathesis. Focus should be on the catalytic properties of Paladium. Again, read up professor's posting on course website.


Economics - fell asleep.
