The demon core was a 6.2-kilogram (14 lb) subcritical mass of plutonium measuring 89 millimetres (3.5 in) in diameter, which was involved in two criticality accidents.The core was slated for use in a third World War II nuclear bomb, but remained in use for testing after Japan’s surrender.
I used to think beyond 7th grade math is only useful for physicists and statisticians. After the rule of three, which allows you to calculate discounts on prices, diminishing returns start to kick in fast. I’ve remedied that view a bit; geometry and calculus have led to some of histories strongest
Physicists have shown that a concept known as the “arrow of time” can be reversed for certain minute particles. Alex The Shutter/Flickr “By revealing the fundamental influence of initial quantum correlations on time’s arrow, our experiment highlights the subtle interplay of quantum mechanics, thermodynamics and information theory,” the
In order to be considered for this ranking, a college had to appear on either The Advocate’s list of the 100 best colleges for LGBT students or InsideCollege.com’s list of gay …
It isn’t too difficult to find GRE scores by intended major online. In reviewing articles/posts for my post below on anthropology I noted the distinction made between quant & qual methods, and aversions to regressions and ter plots (or the supposed love of biological anthropologists for these
Physicists create negative mass that accelerates BACKWARD when pushed that could help explain dark matter and black holes. Material accelerates backward when pushed, instead of in direction of force
The Case Against Reality. A professor of cognitive science argues that the world is nothing like the one we experience through our senses.
Haroutune Krikor “Harry” Daghlian Jr. (May 4, 1921 – September 15, 1945) was a physicist with the Manhattan Project which designed and produced the atomic bombs that were used in World War II.
A list of prominent (or once-prominent) creationists whose doctoral degrees are either honorary or of suspicious origin.
Have physicists finally worked out how NASA’s ‘impossible’ EmDrive propulsion system works? A new paper argues the ‘pilot wave theory’ could explain how EmDrive works
