Fahrenheit scale - Daniel Fahrenheit arbitrarily decided that the freezing and boiling points of water would be separated by 180 degrees, and he pegged freezing water at 32 degrees. So he made a thermometer, stuck it in freezing water and marked the level of the mercury on the glass as 32 ...
Take this example. There are some creationists who say that Occam's razor proves their ideology is correct. After all, isn't it a more simple explanation to say that God created life, the universe and everything than to say it was created by a Big Bang, followed by an astounding series...
My American parents relocated our young family to Berlin when I was three years old. My exposure to America was limited to holidays spent stateside and awfully dubbed Disney Channel broadcasts. As the few memories I had of living in the US faded, my affinity for Germany grew. I began to ...
Until the early 1900s, hair coloring was made from a wide range of herbal and natural dyes. Flying in the face of other chemists who found the development of hair coloring trivial and unworthy of their time, French chemist Eugene Schuller created the first safe commercial hair coloring in 190...

the Sun's core averages about 15 million Kelvin (15 million Celsius, 27 million Fahrenheit). It's tough to describe temperatures like these in relatable terms because they're so far outside everything humans experience. The core of a star reaches temperatures—energy levels, really—we don'...
In an average home in which the temperature is 68 degrees Fahrenheit, the relative humidity should ideally be between 30 and 50 percent. If you're struggling to reach that range, a dehumidifier may come in handy. Dehumidifiers remove excess moisture from the air, improving the comfort and heal...
Photons are waves and particles that are created in the sun's core (the hottest part of the sun) through a process called nuclear fusion. The sun's core is a whopping 27 million degrees Fahrenheit. This extreme temperature and pressure causes hydrogen atoms to collide and fuse, creating ...
Early cultures used meteorites to craft weapons and jewelry long before anyone knew how to extract iron from ore.
