Amazing Robert Adler: Adler’s tube, Adler’s equation, and more

The article is devoted to Robert Adler, the man who combined activities as theoretical physicist, an experimental physicist and engineer-inventor, the owner of more than 200 patents. Brief biographical information about this remarkable man is presented, and a more detailed presentation of the results of his two famous studies is given, known as Adler’s gated-beam tube and Adler’s equation. For those who are interested in the Adler’s contribution to acoustoelectronics, it is important to read the article Kent J., Fakeuchi M., Laux G. Robert Adler’s Touchscreen Inventions (IEEE Ultrasonics Symposium. 2007), the material which gave impetus to write this article. In addition, the original results are presented of generalization of the Adler’s equation and analysis of generalized models using modern methods of nonlinear dynamics.
