Practical science: use latent heat to build better thermal insulation

When a solid changes the phase gets into a liquid it does so by “eating up” heat. Also, when a liquid changes its phase and gets into a solid, it does so by “vomiting” heat. this eaten/vomited heat is called the latent heat. When a solid melts you call that the latent heat of melting […]

X-rays GIF are amazing

X-rays are a spectrum of electromagnetic radiation with a frequency and energy bigger than UV and smaller than gamma. Since they have way bigger energy than visible light glass is opaque to it, but it can go through soft tissues. It will be absorbed by hard tissues like the bones. The following X-ray GIFs are […]
