Newton’s Laws of Motion:
The three physical laws, published by Sir Isaac Newton in 1687, that form the basis for classical mechanics: 1) a body persists its state of rest or of uniform motion unless acted upon by an external unbalanced force; 2) force equals mass times acceleration; and 3) to every action there is an equal and opposite reaction.

Nonlocality:
The rather spooky ability of objects in quantum theory to apparently instantaneously know about each other’s quantum state, even when separated by large distances, in apparent contravention of the principle of locality (the idea that distant objects cannot have direct influence on one another, and that an object is influenced directly only by its immediate surroundings).

Nuclear Fission:
A nuclear reaction in which the nucleus of an atom splits into smaller parts, often producing freeneutrons, lighter nuclei and photons (in the form of gamma rays). The process releases large amounts of energy, both as electromagnetic radiation and as kinetic energy of the resulting fragments.

Nuclear Fusion:
The welding together of two light nuclei to make a heaviernucleus, resulting in the liberation of nuclear energy. An example of this kind of nuclear reaction is the binding together of hydrogen nuclei in the core of the Sun to make helium. In larger, hotter stars, helium itself may fuse to produce heavierelements, a process which continues up the periodic table ofelements as far as iron. The fusion of ultra-stable iron nucleiactually absorbs energy rather than releasing it, and so iron does not easily fuse to create heavierelements.


Nucleosynthesis:
The process of creating new atomic nuclei from pre-existingprotons and neutrons by a process of nuclear fusion. The primordial nucleons (hydrogen and helium) themselves were formed from the quark-gluon plasma in the first few minutes after the Big Bang, as it cooled to below ten million degrees, but nucleosynthesis of the heavier elements (including all carbon, oxygen, etc) occurs primarily in the nuclear fusionprocess within stars and supernovas.


Nucleus:
The tight cluster of nucleons (positively-charged protons and zero-charged neutrons, or just a singleproton in the case of hydrogen) at the centre of an atom, containing more than 99.9% of the atom’smass. The nucleus of a typical atom is about 100,000 smaller than the total size of the atom(depending on the individual atom).
