One Way Only…

This time around, some thing interesting from the world of mathematics.

All of us dealt with functions of different types. We are introduced to functions when very early in school. Single varriable, multi varriable, simple and complex functions. And in college, functions declared, defined and studied. In this post, one such function, known as “one way function” is used widely in computer science.

Wonderful functions from math

Mathematics is full of functions. These functions are applied far and wide else where. Few are used many times where as few others are used little. And very often functions and equations are interchanged. The most celebrated of them all is -

Stray Dogs, Rigor Mortis & Mathematics

In one of the last October month’s outpour’s, we got an unlikely guest at our door step. When I first heard weak howling, I dismissed it to the sound of vicious wind, later it got intense and this time it is not faint, it is a miserable cry. When I checked the door, I found a week old dog pup. Shivering in the cold and rain, it curled itself to the door mat. I felt so pity of it, so got few old clothes and heaved at it for extra warmth. It was already mid night, I left it and slept.

What happened next day was surprise for me. Eager to see, whether the pup was still there, I opened to door to check. There were two dog pups, not one. The new one seemed to be elder to the old one by a day. But both of them were happy. Now, feeding one dog was fine, but two? It was no easy job. But we kept them feeding for quite some time.
