Singularity - Jesse Hyttinen

Updated: Apr 21, 2021

Hi and welcome to the Matladpi blog!

Singularity. What a fascinating subject. You know, the point r = 0 for

r^(-2), is a singularity. Another one could be the point m = 0 for ln(m), or a = pi/2 for tan(a). In addition to mathematical ones, there are also singularities in physics. What if you could add a small term e > 0 in the operation r^(-2), so that (r + e)^(-2) would be e^(-2), rather than the singularity 0^(-2)?

This could be of some use if we for example used Newton's law of universal gravitation, when r = 0. This would not be so bothersome anymore, as there still would be the term e.

Back to the math. The laws of mathematics may seem fragile, when a singularity emerges. And then there is the other side of indeterminate values. For example, 1/n as the function of n, has different diverging limits when n -> 0+ and when n -> 0- . 1/0 is, thus, indeterminate.

I am Jesse Sakari Hyttinen and I will see you in the next post!

A new book - Jesse Hyttinen

I have now written five math books, and may write another one in the following year. The current book includes new viewpoints about very well known numbers. Examples include pi and Euler's number. The

Sum problems - Jesse Hyttinen

Hi and welcome to the Matladpi blog! Let there be two numbers a and b such that their sum is n, n > 0. What numbers should you pick in order to maximize the number a*b? Answer: a = a a + b = n <=> b =
