В тени ПСС?

Почему так широко известен "Мир электрона" Брюсова - и практически неизвестен широкой публике его же "Мир N измерений", написанный двумя годами позже?

Неужели благодаря пошлому ленинскому "Электрон так же неисчерпаем как и атом"? - кажись, единственному, что стопроцентно усваивалось студиозами из "Материализма и эмпириокритицизма".

Хотя, на мой вкус, "Мир N измерений" сильнее. Математичнее, кристалличнее, прозрачнее. Быть может, из-за отсутствия туманно-анафорического "Быть может" "Мира электрона.

Radiation reaction in strong field QED: http://arxiv.org/abs/1301.6499

Anton Ilderton, Greger Torgrimsson

We derive radiation reaction from QED in a strong background field. We identify, in general, the diagrams and processes contributing to recoil effects in the average momentum of a scattered electron, using perturbation theory in the Furry picture: we work to lowest nontrivial order in the electromagnetic coupling alpha. For the explicit example of scattering in a plane wave background, we compare QED with classical electrodynamics in the limit h-bar goes to zero, finding agreement with the Lorentz-Abraham-Dirac and Landau-Lifshitz equations, and with Larmor's formula. The first quantum corrections are also presented.
