Silicon photodiodes, particularly those of the avalanche type, offer speed, efficiency, sensitivity and reliability—both for the systems now in development and future ones at longer wavelengths.

More about the Authors
Hans Melchior.
Swiss Federal Institute of Technology, Zurich, Switzerland.
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.
