A computer in a keyboard

Raspberry Pi Foundation has been developing single-board computers since 2011. Their crowning achievement is the Raspberry Pi 400 computer, built into a compact keyboard.

It might not be very powerful, but it features a 1.8GHz quad-core processor, 4GB of RAM, and even wireless network and Bluetooth 5.0. Moreover, it doesn't overheat after hours of use.

The brain of Albert Einstein 🧠

It was removed within seven and a half hours of his death in 1955, by Pathologist Thomas Stoltz Harvey. Harvey removed and weighed the brain at 1230g, which is less than the average adult male brain (about 1,400 grams). It was then taken to a lab at the University Of Pennsylvania, and dissected into several pieces for further research.

Einstein's brain had a much shorter lateral sulcus that was partially missing. His brain was also 15% wider than the other brains. The thickness of Einstein's cerebral cortex was thinner than the other brains. However, the DENSITY of neurons in Einstein's brain was greater. In other words, Einstein was able to pack more neurons in a given area of cortex. The researchers think that these unique brain characteristics may have allowed better connections between neurons important for math and spatial reasoning.

Polarization of light is a property of light, resulting in the vectors of electric and magnetic fields of light waves are oriented in a plane parallel to the plane in which light propagates.

It occurs when light is refracted, reflected, or passes through an anisotropic medium.

Fluoroscopy of a Dog Eating Food 🐕

Radiography or X-ray and fluoroscopy procedures seem similar. However, fluoroscopy obtains moving images of the inner part of the body and radiography uses gamma rays to develop a static image of the internal structure of a body. We can compare X-ray to a black and white photograph and fluoroscopy to a black and white animation.
