Study Notes
Astrophysics
Astrophysics is a branch of astronomy that uses the principles of physics and chemistry to explain the origin, evolution, and eventual fate of the universe. It involves the study of celestial objects and phenomena, such as stars, galaxies, and black holes, as well as the fundamental laws of physics that govern their behavior.
Cosmology
Cosmology is the study of the universe as a whole, including its origins, evolution, and eventual fate. It involves the study of the large-scale structure of the universe, the distribution of matter and energy, and the fundamental laws of physics that govern its behavior.
Planetary Physics
Planetary physics is the study of the physical properties of planets, including their composition, structure, and behavior. It involves the study of the planets in our solar system, as well as those around other stars (exoplanets).
Radioaktivität (Nuclear Physics)
Radioactivity is a property of certain atoms, called radioisotopes, that emit particles or energy in the form of ionizing radiation. This property is due to the instability of the atom's nucleus, which can decay through various processes, including alpha decay, beta decay, and gamma decay.
Nuclear Reactors
Nuclear reactors are devices that use the heat generated by nuclear reactions to produce electricity. They work by controlling a chain reaction in which the nuclei of atoms emit neutrons, which then cause other atomic nuclei to split and release more neutrons, producing a self-sustaining reaction.
Nuclear Medicine
Nuclear medicine is a medical specialty that uses radioactive isotopes to diagnose and treat diseases. It involves the use of radioactive drugs, called radiotracers, which are taken up by specific cells or tissues and can be detected by specialized imaging devices, such as positron emission tomography (PET) scanners.
Nuclear Waste
Nuclear waste is the byproduct of nuclear reactions, including spent fuel from nuclear reactors and waste from nuclear medicine. It is a significant environmental concern due to the long-term radioactivity of some of these materials, which can pose a risk to human health and the environment if not properly managed and stored.
