Classical mechanics is the branch of physics used to describe the motion of macroscopic objects. [1] It is the most familiar of the theories of physics. The concepts it covers, such as mass, acceleration, and force, are commonly used and known. [2] The subject is based upon a three-dimensional Euclidean space with fixed axes, called a frame of ...

In particle physics, SO(10) refers to a grand unified theory (GUT) based on the spin group Spin(10). The shortened name SO(10) is conventional [ 1 ] among physicists, and derives from the Lie algebra or less precisely the Lie group of SO(10), which is a special orthogonal group that is double covered by Spin(10).
An animation of the figure-8 solution to the three-body problem over a single period T ≃ 6.3259 [13] 20 examples of periodic solutions to the three-body problem. In the 1970s, Michel Hénon and Roger A. Broucke each found a set of solutions that form part of the same family of solutions: the Broucke–Hénon–Hadjidemetriou family. In this ...

In July 2013, José Menéndez, a physics professor at the Arizona State University Tempe campus published an article titled "Impressionism, Realism, and the aging of Ashcroft and Mermin" in Physics Today that stated: "It is undoubtedly one of the best physics books ever written, but it is not aging well". [14]
The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
In particle physics, the most important hierarchy problem is the question that asks why the weak force is 10 24 times as strong as gravity. [10] Both of these forces involve constants of nature, the Fermi constant for the weak force and the Newtonian constant of gravitation for gravity.
