Meet a Math Teacher Who Is Also a Male Model

A PhD in engineering that loves to train his body. He teaches math and in math, theories are disapproved with counterexamples. So I think it’s safe to say that he is the counterexample to the myth that an exercised body means less intelligence!

Beautiful Equations – BBC

“Beautiful Equations” is an extraordinary documentary about some of the most known equations and how did they changed the world. This documentary produced by BBC takes us in a journey through this wonderful world of mathematics.

You may think that math isn’t for you, however the main role is played by an artist and writer (Matt Collings)… This means that every equation is explained in order for he understand therefore we can also understand. I had a lot of fun watching this documentary and learnt a lot from a wide range of subjects. I just had to share this after posting a mathematical post :p Have a nice day! 😀

The Simpsons and Fermat’s Last Theorem

Today I woke up and I saw a facebook post with a video regarding the math underlying the popular animated series “The Simpsons”. I realized I had never notice that subtle numbers that usually are on the background. What is funny about them is that they have a mathematical purpose i.e. they are not random numbers. They are, indeed, numbers chosen by their rare characteristics. [1] So here is the video…

The video was made by the London Science Museum and you can check their site, it seems very interesting. [2]

Returning to “The Simpsons”, I felt I hadn’t understood it well so I searched and I found out this explanatory video.

Now I finally had understood, but I believe that many if us never heard about the Fermat’s last theorem so I decided to put here another video.

I will let interesting references, try to watch them. [3] I hope you learnt something new because I learnt that even an animated series can make fun of math… 😀

A Universe From Nothing – lecture

This summer I finally managed to saw the movie “The Unbelievers”, a movie that I highly recommend (whatever your beliefs might be). After I watch it I made some research about Lawrence Krauss because I had never heard his name. I found a lecture he gave about the Universe and the current theories about it.

Krauss is Foundation Professor of the School of Earth and Space Exploration at Arizona State University and director of its Origins Project. [1] He is a theoretical physicist who beseech explanations for cosmology. Particularly devoted to the themes of the begin of the Universe and it’s ending.
I’m fascinated about astrophysics and I have studied a bit of it (through minutephysichs, ed.ted and wikipedia) so for me it was an awesome way of giggling and have a good time learning more and remember about dark energy, dark matter, cosmic microwave background, etc… [2]
All this for saying that you might want to study a little (e.g. wikipedia), in order to fully understand the talk.
Hope you enjoy it and learn something!

How can you measure Earth’s circumference with the sun? Eratosthenes answers…

First things first, let’s know who was Eratosthenes, then we will proceed for the answer to this task.

Eratosthenes of Cyrene was a Greek mathematician, geographer and astronomer (he yearned to understand the complexities of the entire world so he was devoted to many areas).[1] He lived between 276 BC – 194 BC and during that time he changed the way we view the world. He created geography and made some progress in science especially mathematics (he created a tool for discovering prime numbers).[2] He is now known for being the first person to measure the Earth’s circumference. [3]

If you didn’t understand it completely, here is better explained. (Any doubt or suggestion be sure to leave it in the comment section)
