Top 10 方程
1
Maxwell’s four equations describing how an electromagnetic field varies in space and time.
2
Euler’s equation of momentum-flow and force-density in fluid dynamics.
3
Newton’s Second Law (F=ma) - ‘The rate of change of momentum of a body is equal to the resultant force acting on the body and is in the same direction’.
4
Pythagoras’s Theorum (a²+b²=c²) - In any right triangle, the area of the square whose side is the hypotenuse (the side of a right triangle opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.
5
Schrödinger’s equation describing the time-dependence of quantum mechanical systems.
6
Boltzmann equation describing the statistical distribution of particles in a fluid.
7
Principle of Least Action (or Principle of stationary action)
8
De Broglie’s equation - showing that the wavelength is inversely proportional to the momentum of a particle and that the frequency is directly proportional to the particle’s kinetic energy
9
Fourier Transformation - an integral transform that re-expresses a function in terms of sinusoidal basis functions.

Einstein’s field equations for General Relativity
