What is "Theoretical Physics" ? Einstein, however, rederived the Lorentz transformations on the basis of two new fundamental postulates [9], of the invariance of the laws of physics and the invariance of the speed of light, between inertial observers, thus eliminating the need for an aether. I have a vague idea why people are interested in that and for the most part Id advice them to rethink their interest - but thats not what I am going to ask about. When I ask them what they mean by "theoretical physics", I often get a reply that to the effect that they want to study string theory, elementary particles, etc.. Abbott, the William Bloor Professor in Neuroscience, Physiology and Cellular Biophysics, was a theoretical physicist until the late 1980s, when it struck him that it might take decades to see the fruits of his research. Kadanoff's work in the theory of phase transitions in statistical physics, for example, led to a better understanding of the conversion of water to ice or water to water vapor. - posted in Physics: I just read another of those posts where someone said hes a layman with interest in and Theoretical Physics. Physics Researcher Part of New Effort to Finally Complete Quantum Theory. The response I get is of the type "I want to do theoretical physics". We define the distance measure or metric over the space as the scalar part of the geometric product, which for the special case of two vectors reduces to the dot product as shown in Eq. Another instance I met the term Generally, I tend to think of it more as a method than a field. It is more a rule than an exception that theoretical physicists have developed mathematical methods unknown to mathematics and lacking originally proper justification of some of their features.
