Nuclear physics Quotes

“When I entered medical physics in 1958 there were fewer than 100 in the U.S. and I could see many opportunities to apply my knowledge of nuclear physics.”

“You can take the entire world of physics with all of its macrocosm and microcosm, its quantum mechanics and nuclear physics and reduce it to one word: energy. It's all energy. Scientists say that if you can't measure it, weight it, or see it, it doesn't exist. Well, no one has ever seen energy. We can see its effects, but not "it.”

“(The string is extremely tiny, at the Planck length of 10 ^-33 cm, a billion billion times smaller than a proton, so all subatomic particles appear pointlike.)If we were to pluck this string, the vibration would change; the electron might turn into a neutrino. Pluck it again and it might turn into a quark. In fact, if you plucked it hard enough, it could turn into any of the known subatomic particles.Strings can interact by splitting and rejoining, thus creating the interactions we see among electrons and protons in atoms. In this way, through string theory, we can reproduce all the laws of atomic and nuclear physics. The "melodies" that can be written on strings correspond to the laws of chemistry. The universe can now be viewed as a vast symphony of strings.”
