yes they are I'm only in first grade but i was taught this
Sir Issac Newton-- formulated theories of gravity Pierre and Marie Curie --discovered radioactivity Albert Einstein-- developed theories of relativity see links Rutherford. Discovered small charged nucleus of atom. Split the atom.
Nobody discovered it. The division of organisms into animal or plant kingdoms is something that developed over years
The process of nuclear fission was discovered by German chemists Otto Hahn and Fritz Strassmann in 1938. They bombarded uranium with neutrons and found that it split into lighter elements, releasing a large amount of energy. This breakthrough laid the foundation for the development of nuclear weapons and nuclear power.
Albert Einstein developed the theories of general relativity and special relativity. He also did work in quantum theory. (He won a Nobel prize for his work with light.)
Maltodextrin was discovered in the early 20th century by Russian scientist, Prof. Alexander Samoylovich Marggraf. He developed the process of hydrolyzing starch to create maltodextrin.

he discovered 5 theories.
Theories change because more/different information is discovered.

Max Plank
This is a difficult question to answer as Freud developed numerous theories (many of them famous) over the course of his career. Also, one cannot tell if this question means to ask how long it took Freud to develop his theories or how long it took for his theories to be recognized and respected by the scientific community.
Johannes Kepler
He discovered the power of electricity, invented the light bulb, developed theories about DC (direct current), and proved the dangers of AC (alternate current).
he discovered digitalis which cures dropsey
Classical Capitalism
Isaac newton discovered the law of gravity.
