[1509.02504] Electric charge in hyperbolic motion: The early history and other geometrical aspects
We revisit the early work of Minkowski and Sommerfeld concerning hyperbolic motion, and we describe some geometrical aspects of the electrodynamic interaction. We discuss the advantages of a time symmetric formulation in which the material points are replaced by infinitesimal length elements.

SPACE AND TIME: An annotated, illustrated edition of Hermann Minkowski's revolutionary essay: http://web.mit.edu/redingtn/www/netadv/SP20130311.html

Einstein's Most Famous Thought Experiment
When Einstein abandoned an emission theory of light, he had also to abandon the hope that electrodynamics could be made to conform to the principle of relativity by the normal sorts of modifications to electrodynamic theory that occupied the theorists of the second half of the 19th century. Instead Einstein knew he must resort to extraordinary measures. He was willing to seek realization of his goal in a re-examination of our basic notions of space and time. Einstein concluded his report on his youthful thought experiment:

"One sees that in this paradox the germ of the special relativity theory is already contained. Today everyone knows, of course, that all attempts to clarify this paradox satisfactorily were condemned to failure as long as the axiom of the absolute character of time, or of simultaneity, was rooted unrecognized in the unconscious. To recognize clearly this axiom and its arbitrary character already implies the essentials of the solution of the problem."

Edge.org: Q-Bio, the most interesting recent [scientific] news
Applied mathematicians and theoretical physicists are rushing to develop new sophisticated tools that can capture the other, non-genomic challenges posed in trying to quantify biology. One of these challenges is that the number of individuals in a community may be large, but not as large as there are molecules of gas in your lungs, for example. So the traditional tools of physics based on statistical modeling have to be upgraded to deal with the large fluctuations encountered, such as in the number of proteins in a cell or individuals in an ecosystem. Another fundamental challenge is that living systems need an energy source.

They are inherently out of thermodynamic equilibrium, and so cannot be described by the century-old tools of statistical thermodynamics developed by Einstein, Boltzmann and Gibbs. Stanislaw Ulam, a mathematician who helped originate the basic principle behind the hydrogen bomb, once quipped, “Ask not what physics can do for biology. Ask what biology can do for physics.” Today, the answer is clear: biology is forcing physicists to develop new experimental and theoretical tools to explore living cells in action.
