Earlier this year, JWST researchers reported on measurements built on last year’s confirmation based on Webb data that Hubble’s measurements of the expansion rate were accurate, at least for the….
The original version of this story appeared in Quanta Magazine. David Bessis was drawn to mathematics for the same reason that many people are driven away: He didn’t understand how….
If you double the radius of a balloon, you increase the volume by a factor of eight (since volume is proportional to the radius cubed). But what about the material….
In the case of the AMANDA experiment, early tests in Greenland and later tests at the South Pole began to provide these happy accidents. “It was discovered that the ice….
I get a minimum height of 2.5R. So if the loop is 4 meters high (with a radius of 2 meters), the car would have to start 5 meters above….
In the world of quantum physics, another record appears to have just been broken. In a paper listed on the preprint site ArXiv, researchers at the University of Science and….
“It provides a natural framework, or a bookkeeping mechanism, to assemble very large numbers of Feynman diagrams,” said Marcus Spradlin, a physicist at Brown University who has been picking up….
With the extra downward force, the only way for the forces to add up to zero is if the normal force increases. This means the frictional force is greater, so….
In Wednesday’s Future Perfect newsletter, my colleague Dylan Matthews wrote about the case for skepticism about this year’s Nobel Prize in Economics winners. His argument was that while their theories….
“With support from my department head JD Sukhoo and the senior school management team, I have facilitated several science competitions such as the South African Institution of Civil Engineering (Saice)….
