In episode 2 of “Exposed,” from our friends at San Francisco Public Press, we explore a little-known chapter in San Francisco’s nuclear era: human experiments carried out to assess the health effects ...

Jonny Nelson introduces an animated explanation of black body radiation. All objects are continually absorbing and emitting infrared radiation, for example a heater (radiator). There are no known ...

New atomic clocks are more accurate than those used to define the second, suggesting the definition might need to change ...

The year was 1900 and Max Planck was a young physicist working on the problem of blackbody radiation ... Does the uncertainty found in experiments stem from the physical world, from our ...

Russell, R. S., and Martin, R. P., Nature, 163, 71 (1949).

The base played a key role in the Cold War nuclear era, when it housed a research institution known as the Naval Radiological Defense Laboratory, which studied the human health effects of radiation.

(Courtesy: R Jacobson/NIST) A new way to measure the temperatures of objects by studying the effect of their black-body radiation on Rydberg atoms has been demonstrated by researchers at the US ...

On the other hand, official curricular documents for physics teacher training in Argentina, as well as for secondary-level physics education, include contents such as blackbody radiation, the ...
