TL;DR: The most successful subscription translation journal to date is the Russian Journal of Experimental and Theoretical Physics (JETP) published by the American Institute of Physics (AIP).
Abstract: Some five years ago, the American Institute of Physics began the translation of the Soviet Journal of Experimental and Theoretical Physics under the title Soviet Physics—JETP. In the five years since then the circulation of this translation journal has increased to more than 1000, making it about the most successful subscription translation journal to date.

TL;DR: In this paper, the authors show that, according to Terrell's considerations, an object in motion appears to be contracted in the direction of motion by a factor [1−(υ/c)]1/2.
Abstract: I would like to draw the attention of physicists to a recent paper by James Terrell in which he does away with an old prejudice held by practically all of us. We all believed that, according to special relativity, an object in motion appears to be contracted in the direction of motion by a factor [1−(υ/c)]1/2. A passenger in a fast space ship, looking out of the window, so it seemed to us, would see spherical objects contracted to ellipsoids. This is definitely not so according to Terrell's considerations, which for the special case of a sphere were also carried out by R. Penrose. The reason is quite simple. When we see or photograph an object, we record light quanta emitted by the object when they arrive simultaneously at the retina or at the photographic film. This implies that these light quanta have not been emitted simultaneously by all points of the object. The points further away from the observer have emitted their part of the picture earlier than the closer points. Hence, if the object is in moti...

TL;DR: The Symposium on the Engineering Aspects of Magnetohydrodynamics as mentioned in this paper was held at the University Museum of the University of Pennsylvania (UMU) in the early 1970s.
Abstract: The progress, or lack of progress in some cases, which is being made toward the practical utilization of magnetohydrodynamics was the subject of an all‐inclusive meeting with the rather lengthy title of “Symposium on the Engineering Aspects of Magnetohydrodynamics”. The gathering, which was sponsored by the Basic Sciences Committee of the American Institute of Electrical Engineers, had the advantage of using the auditorium of the University Museum of the University of Pennsylvania. This auditorium was large, the seats were comfortable, free parking was available, and the acoustics and visibility were far superior to that of many recent meetings this writer has attended. The arrangements committee, under R. M. Showers, is to be congratulated. We hope this auditorium is used more often in the future.
