Mass is the concept that enables us to say that an object (or an idea) is weighty or massive.

Context

• Issac Newton needed a mathematical definition of what caused gravity and so defined it thus^[1]

  The quantity of matter is the measure of the same, arising from its density and bulk conjucntly ... It It is this that I mean hereafter everywhere under the name body, or mass. And the same is known by the weight of each body, for it is proportional to the weight, as i have found by experiments on pendulums, very accurately made, which shall be shown hereafter.

• There are these types of mass as commonly defined:

1. rest,
2. inertial. F = ma, resistance to acceleration
3. gravitational. F = m₁m₂r²
4. Momentum. mass relates a body's momentum p to its linear velocity v: p = mv.
5. Energy E = mv² / 2

Solutions

Einstein

General Relativity

Higgs

• How the Higgs Field (Actually) Gives Mass to Elementary Particles One effect of the Quantum Field theory is the need for a field to explain Mass. This has been named the Higgs Field and, with great fanfare, in 2012 the discovery of the Higgs particle was announced.
