Scientists have developed a high-resolution magnetic line camera to measure magnetic fields in real time. Field lines in magnetic systems such as generators or motors, which are invisible to the human ...
In 2009, NASA's Chandra X-ray Observatory released a captivating image: a pulsar and its surrounding nebula that is shaped like a hand. Since then, astronomers have used Chandra and other telescopes ...
Earth is surrounded by a magnetic field generated by electric currents from within the planet. Compasses take advantage of this field to identify north and serve as a navigational aid. But one social ...
It is known that the sun’s corona — the outermost layer of the sun’s atmosphere — is roughly 100 times hotter than its photosphere — the sun’s visible layer. The reason for this mysterious heating of ...
Farmers and herders have known for centuries that herds of cattle have an uncanny ability to all point in the same direction. Last year, a group of German and Czech scientists discovered the reason ...
The traditional method for visualizing magnetic fields, which your science teacher probably demonstrated at some point, is to sprinkle some iron filings onto a piece of paper and hold it over a magnet ...
"Turbulence remains one of the greatest unsolved problems in classical mechanics." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. In between all ...
Many prominent phenomena originate from geometrical effects rather than from local physics. For example, the 'hairy ball' (HB) theorem asserts that a hairy sphere cannot be combed without introducing ...
