describes relation between side lengths in a right angled triangle
a basic rule of logarithms that says the logarithm of a product is equal to sum of the logarithm of the product's factors
the definition of the derivative of a function f at the point t
the formula used in classic physics to describe the amount of gravitational force between masses m1 and m2
the definition of i as the square root of minus one
the relation between the number of vertices, edges and faces in polyhydra
the probability distribution for real valued random variables (bell curve)
a criteria that u has to meet in order to be a wave function (like sin or cos)
a possibility do approximate a function by overlapping wavefunctions
describes a fluids motion (flow)
a collection of formulas describing properties of magnetic and electric fields (to me this the most impressing one as it somehow has the speed of light in it - in 1865.)
an axiom in thermodynamics stating that the entropy of a system is only getting bigger or staying the same, but never gets smaller
the energy of resting masses stating that mass is "a form of" energy. (There should actually be more parts to this equation as a mass can also be moving, be hot etc. I guess this short version just looks more pretty)
"describes the motion of particles in quantum mechanics" - by
"The "Information Theory" equation is entropy (...) Basically tells us the bits we need to encode events, very important for computers & the internet." -
"(...) describes a sequence where small changes to the starting value are dramatically and unpredictably amplified as the sequence progresses." - by
"(...) allows you to accurately value a time limited contract to buy/sell an equity at value X for the length of the contract." - by
