Pi is the ratio of a circle’s circumference to its diameter. And it doesn’t matter how big or small the circle is, the ratio always stays the same: pi. That’s why pi is called a constant. Authors: ZDF/Terra X/Bilderfest/Lena Paul/Dirk Hagen/Saba Bussmann/Jochen Schmidt Translation and dubbing: alu
Equations are used everywhere: in computers, business, internet searches, medicine to name a few examples. Which is why we study them a lot in Maths. We have names to describe the different parts: coefficients, variables, constants and exponents. A variable is a symbol for a number we don’t know y

There are two leading ways to measure the universe's rate of expansion, and for fifteen years, they more or less agreed with one another. Not anymore, and that’s a big deal. Visit http://science.nasa.gov/ for more. Click here to see more videos: https://alugha.com/NASA

The law of mass action is applied to the autoprotolysis of water. Through further considerations, a constant Kw can be defined. This is called the ionic product of water. This is the basis of the pH value. Original: "Wolfgang Dukorn" Original: German. All translations in this video have been done
In algebra we have lots of different names for different things: expressions, equations, formulae and identities are all slightly different versions of similar things. Then within these, we have variables, constants, coefficients and exponents to describe the different parts. We also need to know wh
The reaction speed of the enzyme-catalyzed reactions depends on various factors. In this screencast, the dependence on the substrate concept is explained and the curve is derived. Finally, the Michaelis constant is described. Original: "Wolfgang Dukorn" Original: German. All translations in this v
Homeostasis is a term first defined by Claude Bernard in 1865. It means maintaining a constant internal environment. This is a bit like how our brain works. Sensors all around the body are measuring various things and sending the information back to the brain the brain in does its best to keep all t
Self-improvement is not a new phenomenon for human beings. It’s been shown in advertising commercials and just generally seeing people living “better” lives than us. But the self-improvement culture can make us feel disempowered like we should be someone else. Watch this video to know why. Disclai
