What do you think about this idea: "To make a machine that thinks, the machine must carry the conceptual hierarchy. It must now be able to detect which entity is more abstract, and which entity is an instance of that abstract idea."

Stefan Buijsman, 20, just finished a PhD in the philosophy of mathematics. He tells The Local what his work is all about, and why Stockholm was the best place to do it.

Infinity isn't a form of magnitude but an idea of the unlimited.

Euclid's Elements

The history of Euclid's Elements.

Melvyn Bragg and guests discuss Euclid's Elements, a mathematical text book attributed to Euclid and in use from its appearance in Alexandria, Egypt around 300 BC until modern times, dealing with geometry and number theory. It has been described as the most influential text book ever written. Einstein had a copy as a child, which he treasured, later saying "If Euclid failed to kindle your youthful enthusiasm, then you were not born to be a scientific thinker."

There's a simple way to organize genealogies that has some nice mathematical properties.
There's a simple way to assign numbers to people in a family tree that's surprisingly useful.

People tend to think that there is a 50% chance to give a correct statement on the number X. This article presents a strategy for higher success rates!

Did you Know?

We need leap years because it takes Earth 365 days, 5 hours, 48 minutes and 45 seconds to orbit the Sun, causing the calendar year to become more and more out of sync with the solar year over time. Every year, the calendar falls about one-quarter of a day behind the solar year. Over time, Jan. 1 would come earlier in winter, then in the fall. After about 780 years, New Year’s Day would coincide with the summer solstice. If we didn’t have leap days, * February 2016 would actually be July 2017 and today would be Sept. 10, 2017.

* If you begin counting from the time Julius Caesar met Egyptian astronomers and created a new calendar.

I get confused by synthetic division a lot, so I tend to use this factor by grouping method instead because it's faster for me to do and easier for me to understand. Does anyone else here find synthetic division kind of convoluted or do you think it's just something you have to get used to?
