For the first time, scientists have "photographed" a rare plasma instability, where high-energy electron beams form into ...

A piece of aluminium has a mass of 200 kg and a volume of 0.074 m 3. Calculate its density in kg/m 3, to two significant figures. The kilogram (kg) is the standard unit for mass. The cubic metre ...

Phase transitions in the collective motions of self-propelled particles are directly impacted both by the initial velocity of each particle ... a sufficiently high density, and be below a certain ...

The quantum mechanical mathematics of isospin is very similar to that of ordinary particle spin in quantum mechanics and quantum electrodynamics. It's known that nuclear matter at any density has ...
