Anotace:

„Astrophysics“ follows up freely the standard lectures from physics. In relatively attractive area then student recapitulates the knowledge of some parts of the physics (mechanics, optics, relativity, quantum mechanics, radiation, differential and integral calculations). Students will become familiar with some numerical methods and some of them will take part in construction of the www pages. The lecture is supplemented with a three-day practical camp course.

Požadavky:

Presence at the seminars and the students must obtain minimally 50% of available points in the www test.
