In summary, factor physics is a branch of physics that focuses on the forces and interactions between particles and the fundamental laws governing their behavior. It is closely related to other areas of physics and has many practical applications, including the development of technologies and understanding the behavior of materials under extreme conditions. However, there are still many unsolved questions in factor physics, such as the unification of the four fundamental forces and the nature of dark matter and energy, that scientists continue to research and study.

for the following question:
show that the thickness x of an absorber required to reduce the intensity of radiation by a factor of 2 is given by x=0.693/(miu)

my problem:
what is meant by "a factor of 2"?

It means that the energy is reduced to one half its starting value. BTW - 0.693 looks suspiciously close to [itex]\ln 2[/itex]. ;)

thanks! :)
so usually, factor=mutiple?
 

1. What is factor physics?

Factor physics is a branch of physics that deals with the forces and interactions between particles and the fundamental laws governing their behavior.

2. What are the main factors that influence physical phenomena?

The main factors that influence physical phenomena are mass, energy, and the four fundamental forces (gravity, electromagnetism, strong nuclear force, and weak nuclear force).

3. How does factor physics relate to other areas of physics?

Factor physics is closely related to other areas of physics, such as quantum mechanics, relativity, and thermodynamics, as it helps explain the fundamental properties and behavior of matter and energy.

4. What are some practical applications of factor physics?

Factor physics has many practical applications, including the development of technologies such as nuclear power, semiconductors, and medical imaging. It also helps us understand the behavior of materials under extreme conditions, such as in space or in high-energy collisions.

5. Are there any unsolved questions in factor physics?

Yes, there are still many unsolved questions in factor physics, such as the unification of the four fundamental forces, the nature of dark matter and dark energy, and the behavior of matter at the smallest scales. Scientists continue to study and research these areas in order to deepen our understanding of the universe.
