Explain the role of nuclei in cloud development. Explain how fireworks work. Explain how x-rays are produced when an electron beam falls on a metal target. Explain how viruses reproduce. Explain what happens in photosynthesis. Describe how sulphuric acid is produced in the atmosphere. ...
The first computer screens, developed in the mid-20th century, worked much like televisions, which used to build up their moving pictures by "scanning" beams of electrons (tiny charged particles inside atoms, also called cathode rays) back and forth from top to bottom and left to right—like...
The Sun, a seething ball of nuclear power, has enough fuel onboard to drive our Solar System for another five billion years—and solar panels can turn this energy into an endless, convenient supply of electricity.Solar power might seem strange or futuristic, but it's already quite commonplace...
Generally, when a protein is consistently produced improperly, the root of the issue is first suspected to be genetic. Problems with protein production, unrelated to the encoding genes, are more likely to be temporary or only involve a small number...
In the relativistic frame, the gamma rays are below pair-production threshold and so do not suffer pair-production attenuation. This definitively solves the opacity problem. But unless the Lorentz gamma factor of the bulk motion can be fine- ...
Same as for the inner layers, the photo resist is applied to the outer layer, the prepreg panel and black ink film joined together is now blasted with UV rays in yellow room. The photo resist hardens. The panel now goes through the machine to wash away hardened resist protected by black...
light: robots could just as easily seeX raysor infrared (with heat detectors). Robots could also navigate like homing pigeons by following Earth's magnetic field or (better still) by using GPS to track their precise position from one moment to the next. Why limit ourselves to human ...
