You'll be an advocate for middle ground solutions and viewpoints in our way to treat
the climate challenge
We should accept the fact that there is climate change and figure ways to solve the
issue.
Since its not possible to drastically cut the emission of

Lecture 7 Interactions between Particles and Matter
Interaction between alpha ( ) particles and matter
a) Energy loss per unit length in charged particles
: 2 positive charges
interacts with electrons of atoms in matter (long-range force)

Lecture 5 Energy, Temperature, Mass
1. Energy Units
a. SI units, Joules
b. The work required to move an electric charge of one Coulomb through
an electric potential of 1 volt
J = C. V
1 coulomb corresponds to 6.25x10^18 electrons
1eV = 1.6x10^-19 J

Long range force(no distance at which it fully vanish

Lecture 8 Nuclear Fusion, Part 1
Small nuclei like to fuse to have a large E. However, the EM force does not want
them to.
Likelihood of fusion reaction
Among the 4 candidates, same reactions are easier than others to imitate.
A physical quantity that mea
