(N/A) According to Richard Feynman,matter is made up of atoms.
This is significant because if mankind does not use this knowledge wisely,there is a chance of extinction or suffering annihilation.
This could be due to a nuclear catastrophe or an environmental disaster.
Atomic Hypothesis: All things are made of atoms. These are little particles that move around in perpetual motion. They attract each other when they are at a little distance apart but repel when they are squeezed into a very small space.
Historically,Kanad in India and Democritus in Greece suggested that matter might consist of indivisible constituents.

An alpha nucleus of energy $\frac{1}{2}mv^2$ bombards a heavy nuclear target of charge $Ze$. Then the distance of closest approach for the alpha nucleus will be proportional to

In the Rutherford's nuclear model of the atom,the nucleus (radius about $10^{-15} \; m$) is analogous to the sun about which the electron moves in an orbit (radius $\approx 10^{-10} \; m$) like the earth orbits around the sun. If the dimensions of the solar system had the same proportions as those of the atom,would the earth be closer to or farther away from the sun than it actually is? The radius of the earth's orbit is about $1.5 \times 10^{11} \; m$. The radius of the sun is taken as $7 \times 10^{8} \; m$.
