If you love math puzzles, you'll love this sequence, discovered by mathematician Lionel Levine in 1997. Neil Sloane, founder of the OEIS (On-line Encyclopedia of Integer Sequences), explains the Levine Sequence – which escalates incredibly quickly – for numberphiles at any math level.
Math's incredibly fun "Levine Sequence" simply explained
Mathematicians analyze the geometries of the Pringle
A Pringle is a hyperbolic paraboloid. Mel Magazine invited several mathematicians to analyze the delicious geometry of the chip. From Mel: Theron Hitchman, Professor of Mathematics at the University of Northern Iowa: Usually, the way mathematicians talk about this kind of thing is in an equation, but I think equations tend to scare people off,… READ THE REST
These ten software innovations transformed scientific research
When I was a mechanical engineer in 1990, I faced a stubborn problem with the design of a disk drive baseplate (an aluminum base that the disk motor and actuator motor were mounted on). When the prototype drive spun up, the baseplate vibrated so much that the read/write heads couldn't stay on track. The first… READ THE REST
How a convience-store-owner hacked the lottery odds and won $27 million
Here's a fascinating story about a convenience-store owner in Michigan, Jerry Selbee, who cracked a Michigan state lottery — and then a similar one in Massachusetts. He didn't do anything illegal; he just realized the lotteries were constructed in such a fashion that under certain conditions, if you bet big and could spend more than… READ THE REST
The Gravita is a trippy lamp that shines while levitating in thin air
"Dude, your lamp is broken." "No. No, dude, it is not." Perhaps the greatest lure of the Gravita Levitating Smart Lamp is that at a glance, it doesn't look like it should work at all. But it also packs in some other useful twists to go along with its unquestioned uniqueness, making it an absolutely… READ THE REST
Save more than 70% off these refurbished iMac and Mac Mini models
Time just flies in computer years. In fact, it's been almost 25 years since the iMac ascended to become Apple's premiere desktop computer. Just a few weeks after announcing the new M1 iMac, the brand's first major redesign in almost a decade, it's now open season on previous generations of iMacs past. In fact, there are… READ THE REST
This course explains what NFTs are
Up until the last few months, it would have been completely acceptable to shrug your shoulders and let your eyes glaze over if someone tried to explain a non-fungible token to you. But after decades of limited ownership over images, gifs, and virtually anything found on the web, the NFT process can now finally give… READ THE REST
