- Neujmin, Grigoriy N.
- Ukrainian astronomer; discovered the asteroid 951
Gaspra.
- neutrino
- a fundamental particle supposedly produced in
massive numbers by the nuclear reactions in
stars. They are very hard to detect since the
vast majority of them pass completely through the
Earth without interacting.
- Newton, Isaac
1642-1727
- English cleric and scientist; discovered the
classical laws of motion and gravity; the bit
with the apple is probably apocryphal.
- Nicholson, Seth Barnes
1891-1963
- American astronomer; discovered Lysithea, Ananke,
Carme and Sinope; also did important work on
sunspots.
- nuclear fusion
- a nuclear process whereby several small nuclei
are combined to make a larger one whose mass is
slightly smaller than the sum of the small ones.
The difference in mass is converted to energy by Einstein's famous
equivalence E=mc2. This is the source of the
Sun's energy therefore ultimately of (almost) all
energy on Earth.
