Each year, tens of thousands of passengers get bumped from their scheduled flights because of overbooking. A new video from TED-Ed explains why companies do it, and why you have a right to be pissed off when it happens.
The first edition of Sir Isaac Newton's Principia Mathematica was sold for $US3.7 million ($5 million) at Christie earlier this week, becoming the most expensive printed science book ever sold at auction — . Albert Einstein described Newton's seminal 1687 work as "perhaps the greatest intellectual stride that it has ever been granted to any man to make".
Video: The story of the history of maths and how zero came to be is actually quite fascinating! They should have taught us that instead of actual maths in high school, if you ask me. Thankfully, Hannah Fry tells us in the animation below all we need to know. There's fascinating bits about how the number system (and zero) was resisted by the Romans, and why it's very important to calculus and things like the binary system.
The dishwasher! The perennial optimization problem. Even the chronically untidy have been known to harbour strong opinions on efficient loading technique. But did you know dishwasher manuals actually include photos and illustrations of ideal rack layouts? (Be honest — did you even realise your dishwasher had a manual?)
Guess the Correlation is a very simple game indeed: Look at a scatter plot, guess the correlation coefficient, win or lose. Are you mathematically minded enough to take on the challenge?
A new fractal analysis of London's dense network of streets and intersections reveals that a green belt meant to encourage migration to the suburbs had the opposite effect. The city has just became denser. People really seem to love urban living, especially in a thriving city like London. The work could shed light on how modern cities evolve, and help guide future urban growth policies.
We now know a little bit more about the dynamics of chocolate fountains, thanks to the efforts of Adam Townsend, a graduate student at University College London. He decided to figure out why that "curtain" of molten chocolate always falls inwards and the ensuing paper appeared last month in the European Journal of Physics.
Calculus: A word that triggers involuntary fear spams in the best of us. But the days of slogging through tedious textbook derivatives are over, if you want them to be. For the past few years, people across the world have studied calculus for free online, by exploring a set of gorgeous, dynamic animations.
