How did we Measure the Speed of Light

The speed of light is 299 792 458 meters per second. Exactly. No seriously. By coincidence? No let me explain. The most successful measurement of C was done in 1972 using laser interferometry… laser interferometry. Sounds familiar? Let me help you, LIGO. Laser Interferometer Gravitational-wave Observatory. Yes the technology used to measure the speed of

The Zipf Mystery

Hey, Vsauce. Michael here. About 6 percent of everything you say and read and write is the “the” – is the most used word in the English language. About one out of every 16 words we encounter on a daily basis is “the.” The top 20 most common English words in order are “the,” “of,”

Frequency, Wavelength, and the Speed of Light | a video course made easy by Crash Chemistry Academy

Hello. In this video we are going to characterize one aspect of light waves by looking at what frequency and wavelength are and how they are related to the speed of light. First we need to understand what frequency is, frequency’s relationship to wavelength, how frequency is measured, and finally looking at how frequency and

Which Way Is Down?

Hey Vsauce! Michael here. Down here. But which way is down? And how much does down weigh? Well, down weighs about a hundredth of a gram per cubic centimeter. It is light and airy which makes it a great source of insulation and buoyancy for water birds but if you let go of down… It
