the integral of the velocity,' said Melkana Brakalova-Trevithick, chair of the math department at Fordham University, who chose this equation as her favorite. the difference in the values of the quantity at the end points of the time interval) is equal to the integral of the rate of change of that quantity, i.e. 'In simple words, says that the net change of a smooth and continuous quantity, such as a distance travelled, over a given time interval (i.e. The fundamental theorem of calculus forms the backbone of the mathematical method known as calculus, and links its two main ideas, the concept of the integral and the concept of the derivative.

While the first two equations describe particular aspects of our universe, another favorite equation can be applied to all manner of situations.

It is fully self-consistent with quantum mechanics and special relativity.' 'That includes, of course, the recently discovered Higgs(like) boson, phi in the formula. 'It has successfully described all elementary particles and forces that we've observed in the laboratory to date - except gravity,' Dixon told LiveScience. The theory can be encapsulated in a main equation called the standard model Lagrangian (named after the 18th-century French mathematician and astronomer Joseph Louis Lagrange), which was chosen by theoretical physicist Lance Dixon of the SLAC National Accelerator Laboratory in California as his favorite formula. Wohlstadter (opens in new tab))Īnother of physics' reigning theories, the standard model describes the collection of fundamental particles currently thought to make up our universe.
