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. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail.
Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity. Mechanical power is also described as the time derivative of work.
The three-body problem is a special case of the n-body problem, which describes how n objects move under one of the physical forces, such as gravity. These problems have a global analytical solution in the form of a convergent power series, as was proven by Karl F. Sundman for n = 3 and by Qiudong Wang for n > 3 (see n-body problem for details
In a report published last year, Goldman Sachs projected that the power demand from data centers would more than double by 2030. It’s an open question whether our power grids are even capable of ...

[1]: 6 Finding a theory of everything is one of the major unsolved problems in physics. [2] [3] Over the past few centuries, two theoretical frameworks have been developed that, together, most closely resemble a theory of everything. These two theories upon which all modern physics rests are general relativity and quantum mechanics.
Apr. 7—Hawaiian Electric contends that it faces an "extremely tight " supply of power at peak use periods, especially when production from wind, solar and hydroelectric facilities is lower than ...
In 1987 a 90-minute loss of power to Nasdaq's automated trading computer, caused by a squirrel, affected twenty million trades. [9] [17] [18] Nasdaq was shut down for about 30 minutes again in 2014 by a squirrel-induced power outage.
