If you add up all the natural numbers from 1 to infinity, you should get a really large version of infinity, but this is not the case. What you get is minus one/twelfth. Watch the following well-made video clip in order to understand how this happens. Related posts: Fundamental Theorem of Arithmetic Nature by Numbers […]

Read More...I found this on Wikipedia, reading about prime numbers: “Inevitably, some of the numbers that occur in nature are prime. There are, however, relatively few examples of numbers that appear in nature because they are prime. One example of the use of prime numbers in nature is as an evolutionary strategy used by cicadas of […]

Many formulae in mathematics, science, and engineering involve π, which makes it one of the most important mathematical constants.For instance, the area of […]
