**The Pythagorean theorem**

a² + b² = c²

Pythagoras was a Greek mathematician who lived about 2500 years ago, and who developed the most famous formula in geometry, possibly in all of mathematics! He proved that, for a right triangle, the sum of the squares of the two sides that join at a right angle equals the square of the third side.

this matches my experiences in the tech community. What about yours?

All these decades of similar "What's next in the sequence?", I have never seen this interesting one.

Just awesome!

I have always loved how something as simple as a pentagon can lead to such non-trivial mathematical connections such as the golden ratio.

a great experiment for the inquisitive. Always a great object lesson for students to first try to guess what will happen before they see the answer.

Well have all, sometime in our lives, talked about a regular dice that is biased. But this is a really mind-twisting thought: an irregular dice that is unbiased!

fascinating idea: Self-healing concrete.

Bacteria is added as an extra ingredient at the time of dissolving and mixing the concrete. It remains dormant until the concrete cracks and water gets in.

Most jokes are funny as they reflect a degree of truth.

an interesting idea, especially with the new trends of infinite scroll.

very detailed and insightful commentary on the state of technology.

I wonder how many other potential achievements and discoveries have been lost because we failed to give women equal opportunities to shine?!

This is a fascinating commentary to remind us that often the greatest acheivements and discoveries begin with people being naturally inquisitive and curious.

**Machine Learning used to reconstruct ancient languages**

I think it is cool that Machine learning is being used in so many aspects of society!

"These days an absolutely staggering amount of research and development work goes into the very coarsely defined field of “machine learning.” Part of the reason why it’s so coarsely defined is because it borrows techniques from so many different fields. Many problems in machine learning can be phrased in different but equivalent ways. While they are often purely optimization problems, such techniques can be expressed in terms of statistical inference, have biological interpretations, or have a distinctly geometric and topological flavor. As a result, machine learning has come to be understood as a toolbox of techniques as opposed to a unified theory."
