Blue sky with cirrus clouds This is an easy question to ask but the answer is pretty hard. The light that comes from the Sun to Earth looks white, but really it is made up of all different colors of light mixed together. You can see this by using a glass of water or a glass prism to break up [...]

A cloudy glass of water You can see for yourself that blue light scatters more than red light. This is the same way that John Tyndall showed why the sky was blue in 1859. Fill a drinking glass with water, and then add two spoonfuls of milk - almond milk is okay if you are dairy-free [...]

Rainbow over Amazon river Light is made of billions of tiny particles called photons. These photons travel from one place to another in waves. Visible light is the subset of photons that move at a wavelength that we can see. Among the different photons that are in visible light, the ones that have the [...]

Emilie du Chatelet, a French philosopher in the 1700s Emilie du Chatelet's rich father, who was interested in literature and science, hired tutors to homeschool her, instead of sending her to a convent school. She learned Latin, German, Greek, and Italian, as well as math and science. When du Chatelet was 18, she married [...]

Any desk lamp will do You can get colored lights and thermometers and do the experiment that du Chatelet never carried out. See for yourself whether red light will heat things up more than blue light! Get a regular weather thermometer, and set it up under a strong desk lamp so the light shines [...]
