The standard gange field theory of strong and electroweak interactions is believed to explain all known elementary particle processes up to an energy of at least 1 TeV. It is likely that this model can be enlarged to account for even higher energies, perhaps approaching the Planck scale of 10...
Physics World's 'Book of the Year' for 2016 An Entertaining and Enlightening Guide to the Who, What, and Why of String Theory, now also available in an updated reflowable electronic format compatible with mobile devices and e-readers. During the last 50 years, numerous physicists have tried...
Relativity shows the mathematical relation of time to the distance variables, and in this it is not wrong. There is a certain mathematical equivalence between time and distance, as is shown in the equation x = ct. Einstein and Lorentz saw this equation as representing the speed of light in ...
Wall Street has remained terra incognita for women trying to reach the highest rung. “In theory, this is an analytical business, and what should matter here is performance. And yet in the most analytical of industries it hasn’t mattered...
First is incrementalism. 第一是渐进主义。 Second is risk aversion. People are scared of secrets because they are scared of beingwrong. 第二是风险规避。人们害怕秘密是因为怕犯错。 Third is complacency. Why search for a new secret if y...
I knew that not to be true but I didn't fully get why. Was it optical? Mechanical? Mathematical? Completely mysterious? MOND? String Theory? I am on the side of this being a mathematical answer. The eyepiece doesn't care about the light path it only knows that it is the x fraction...
We now take a closer look at this effective theory. With the quantum minimalism in mind, we assume that the least action contribution dominates the path integral. This is the same as saying the wave function of a single quark is described by a solution to the Dirac equation in which Aα...
The discussion begins with the issue of whether human beings have a right to be wrong in what they believe and in much of what they do (that doesn’t inflict burdens on others). It moves on to a consideration of whether being wrong must always amount to.
(although it is a validation of the theory). Similarly, the ability of general relativity to explain the anomalous movement of Mercury’s perihelion (its point of closest approach to the Sun), which Newtonian gravity could not, worked as a validation of the new theory, but not as a source...
s equations to calculate things. For example, the motion of satellites, or exoplanets. If we don’t need the precision of Einstein’s theory, we simply use Newton to get an answer that is “good enough.” We may have proven Newton’s theory “wrong”, but the theory is still as ...
