The original works of prominent scientists often look archaic and are difficult to read. Try to study calculus by reading the treatises of Newton, for instance, and you will see it. The purpose of texts is to give a streamlined, modern, and relatively easy way to learn a subject. Nevertheless, studying the original works of great masters might be useful in several respects:
This issue of the journal is devoted to analyzing the paper "On the electrodynamics of moving bodies" by A. Einstein. Amongst other it reveals an interesting mathematical trick.
Einstein was looking for a certain function τ(x,t) and derived the following equation for it:
|a||∂τ(0,0)||+ b||∂τ(0,0)||= 0 (1)|
But Einstein applied his out of the box thinking skills and found an elegant way to cope with the problem. He noticed that solution to the differential equation
|a||∂τ(x,t)||+ b||∂τ(x,t)||= 0 (2)|
Those who love viewing everything through the glasses of TRIZ could recognize the transition to another dimension here. Indeed, in order to solve the equation of unknown type given for one point (0,0) only, it was extended to the entire plane (x,t) and thereby converted into an equation of the known type, specifically, differential equation. So, it can be viewed as a manifestation of the transition from point to plane.
Although it is debatable whether this TRIZ analogy is useful or not the usefulness of studying primary sources is beyond the doubt.
