One dyne is equal to 10−5 N or to 10 nsn (nanosthenes) in the old metre–tonne–second system of units.
Positronium (Ps) is a system consisting of an electron and its anti-particle.The ground state binding energy of positronium is half of that of Hydrogen.
The Reynolds number is an experimental number used in fluid flow to predict the flow velocity at which turbulence will occur.
Cavitation is the formation of vapour cavities in a liquid – i.e. small liquid-free zones that are the consequence of forces acting upon the liquid.
