Magnetic Resonance Imaging “sees” inside the body by mapping the position of water molecules, which exist at different densities in different types of tissue. Watch the video for a sample of some impressive MRI images of the human body in action.
We don’t really want to know what happened exactly. Nor whether there was a specific reason for those injuries. Anyway, here you have a collection of X-ray pictures of things that have been stuck way (!) up.
How many female scientists can you name that aren’t Marie Curie? Even today, the stigma about women in science persists, but each of the women in this list have directly contributed to the lexicon of modern life.
Everything you need to know about electromagnetic waves in one poster.
Reflection, refraction, diffraction, oh my! Dive into the wonderful world of electromagnetic radiation–i.e., the energy that travels through space in waves, like x-rays, microwaves and good old visible light.
Each kind of light has a unique wavelength, but human eyes can only perceive a tiny slice of the full spectrum — the very narrow range from red to violet. Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our perception. Lucianne Walkowicz shows us the waves we can’t see.
War in Asia caused the United States to reconsider testing nuclear weapons in the Pacific Ocean and to look for a continental test site. Conflict in Korea justified a less-expensive continental testing site in order to maintain U.S. nuclear weapons superiority. A Nevada site north of Las Vegas was chosen because of its safety features, which included low population density, favorable meteorological conditions (a prevailing easterly wind blowing away from the populous west coast), and good geographical features.
