We learn a lot of equations in school, most of which we forget as soon as we've taken the test. Some equations do have practical uses, however; we may not ever need to use them, but they probably affect our everyday life.
The Pythagorean Theorem helps find the length of a missing side of a right triangle. The formula is a squared plus b squared equals c squared, where c is the hypotenuse and a and b are the other two sides of the triangle.
Einstein's famous mass-energy equivalence equation, often called his theory of relativity, is E equals m c squared, where E is energy, m is mass and c is the speed of light.
Better known as the quadratic equation, a times x squared plus b times x plus c equals zero may dredge up nightmares of algebra teachers shouting, "Complete the square!"
Newton's Second Law of Mechanics states that force equals mass times acceleration. Some have called this the most important equation in physics, although others give this moniker to the Schrödinger equation.
Although most people could answer that Pi equals 3.1416, they may not know the equation that ends in this result. Since Pi is a constant, however, knowing that it equals the circumference of a circle divided by the diameter, you can calculate either the circumference or the diameter if you have the other value.
Most people don't use equations of this nature in their daily lives, and you may never have to know them once you're out of school. You may just find a time when one of them will come in handy, however -- even if it's just to impress some people at a cocktail party with your knowledge of mathematical formulas!
Fascinating list! Thanks for sharing.
I'm pretty mathematical but this list just reminds me of why two semesters of statisitics scrambled my brain!
Well done list.h5
Great equations that resemble life!
