Arabic numbers: why are they shaped like that?

In the image from above you can see why the numbers are looking the way they look now. We can say that we chose style over function, but you get the idea. Number one should have only one angle, number two should have two angles and number three should have four angles. Today we do […]

Brady Haran’s mile of Pi

Ok, that guys is crazy. Brady Haran printed out one mile of Pi, meaning 1 million digits for number Pi. Matt Parker checks out the mile of Pi and then presents some interesting things that can be found along the way. What Matt Parker has found: – Feynmann point : 999999 at position 762 – […]

Fundamental theorem of algebra

Polinomials. They are mean, but they are manageable. If I only had math professors that could explain things like professor David Eisenbud does, then I’d been a better math guy. Right now i look at the Numberphile videos to understand why math is important and how does it help in practical means (spoiler alert: math […]

Holy shift. Look at that asymtote on that mother function! [classic]

The guys at IFL Science have posted this on their Facebook page. I HAD to put it out there as it is outrageously funny ๐Ÿ˜€ That is the graph of f(x)= x/(x-1) and Google’s Graph is exactly the same. An asymtote is a line that does not touch the curve of the graph, as defined […]

How many infinities are there?

Except the fact that there are many infinities the mathematicians have been able to categorize them in a few dozen of such infinities which range from number infinities to space infinities, from cardinal infinities to topological infinities. Vihart is the first person to ever put all these categories in there, for the layman to easily […]

Learn a new way to do math

You draw a rectangle with several sections and the area summed up is the total of the multiplication. It is far easier to calculate 63*47 this way. Via Business Insider.

Facebook math: friends and strangers theorem

The theorem of friends and strangers can eb explained by using the Facebook analogy. Given six people on Facebbok and you’re one of them, you can either be connected or not with any of the other five. Between these six persons you can draw lines (red – not friend, green -friend) and you get 2^15 […]

Minute Physics: is the Universe only Math

Wherever physicists look at the Universe they see the physical laws that govern it and the math that can be used to describe it falls in perfectly. This is why, if you can explain so many things with math, people are asking them selves if the Universe is indeed math. If you ask me, I’d […]

Sexy math

This is what we needed in high school: a cute lady that loves math to also make us love math. Hannah Fry explains the importance of algebra in explaining the phenomenon around us and why using letters like “X” gives us enough flexibility to encompass many answers to out questions. Using letters in algebra lets […]

The sum of all positive numbers is -1/12

Ouch. That is something that can hurt your brain, but actually mathematicians have a ton of tricks up their sleeves. Remember the number i, which is the square root of -1, a thing that would not normally exist if there weren’t a category of complex numbers used in math? In the same way, the sum […]
