On Don Tillman and Rouché’s theorem

On Don Tillman and Rouché’s theorem

For some reason when I was reading Graeme Simsion's book "The Rosie Project" I kept thinking about the Rouché's theorem. I don't know why really since it does not have much to do with the book (nothing really). You see in complex analysis, the Rouché's theorem is a statement about the zeros and poles of meromorphic functions. It is named after the French mathematician Eugène Rouché and of course has nothing to do with a man that eats a lobster…

Made by Planet Earth: The Iguazu Falls

Made by Planet Earth: The Iguazu Falls

The falls of Iguazù are located in Argentina and are one of our many natural wonders. Many people travel to see them when they travel to Argentina or Brazil. And they are truly breath taking to behold. Located on the border between these two countries, it is very easy to move from one side to the other during the excursion. The name "Iguazú" is derived from two words that either originate in the Guarani or Tupi language. Translated to "water…

If we speak of something in the past that would have happened we are speaking of a past participle which is used…

A Drive to Learn

A Drive to Learn

A positive attitude allows us to learn better. Life is built up of a lot of pieces which are almost always unexpected. I would probably have been a scientist if it wasn't for a couple of teachers I had as a teenager that I really disliked. They turned science into something dreaded, a subject that I had previously loved. Around the same time, I had two language and literature teachers who were good at what they did, they were excited…

Understanding And Overcoming Those Sleepless Nights

Understanding And Overcoming Those Sleepless Nights

Hello readers/guests/family, you're all great I hope… Today I decided to write about something that used to be a topic in my life. It is something that can make a sudden appearance in our lives or it might be a steady companion, one that affects many people on a daily basis: insomnia. It's never been fun to lay their awake when you should be soundly asleep in dreamland. The thoughts that run through my head at those times were the…
