New interest has arisen in the wavefront reconstruction process of Gabor. With the aid of the laser, photographic imagery has been produced in which the image is, to all appearances, a three‐dimensional reconstruction of the original, complete with parallax and other visual effects.
Wavefront reconstruction, or holography, is a fascinating photographic process which is a major departure from conventional photography. In this process, discovered in 1947 by D. Gabor of Imperial College, London, the photosensitive device does not directly record an image of the subject; instead, the electromagnetic waves reflected or scattered from the subject are recorded as a standing wave pattern. The resulting photographic record is called a hologram (from the Greek word holos, meaning whole), a name given by Professor Gabor to indicate that the whole, or entirety, of the wave pattern is recorded.

Technical knowledge and skills are only some of the considerations that managers have when hiring physical scientists. Soft skills, in particular communication, are also high on the list.
Research exchanges between US and Soviet scientists during the second half of the 20th century may be instructive for navigating today’s debates on scientific collaboration.
The Eisenhower administration dismissed the director of the National Bureau of Standards in 1953. Suspecting political interference with the agency’s research, scientists fought back—and won.
Alternative undergraduate physics courses expand access to students and address socioeconomic barriers that prevent many of them from entering physics and engineering fields. The courses also help all students develop quantitative skills.
