A New Theory for Systems That Defy Newton’s Third Law
In nonreciprocal systems, “exceptional points” are helping researchers understand phase transitions and possibly other phenomena. ...
In nonreciprocal systems, “exceptional points” are helping researchers understand phase transitions and possibly other phenomena. ... Mathematics is the core basis of life knowing; there’s surely nothing in this world where mathematical applications don’t contribute to their role. Even to understand the basics of a single piece of matter, whether it’s a small needle or a huge sky-touching architecture, a thorough mathematical application must be implemented to derive its shape, dimensions, ...
Mathematician, artist, and engineer George W. Hart of "Möbius ***** bagel" fame has recently been playing with a laser cutter to create head-spinning warped-grid jigsaw puzzles. He came up with an algorithm to generate the initial patterns but "the real fun is step 2," he says, "using a geometric transformation to warp things."

Legendary physicist and mathematician Freeman Dyson, whose mind-blowing work ranged from quantum electrodynamics to nuclear engineering to the search for extraterrestrial intelligence, died last week at 96-years-old. Tim O'Reilly just published a tribute to Dyson's genius, curiosity, kindness and unique lens on, well, everything. From O'Reilly Radar:
When I interviewed Freeman on stage at ...
On Vsauce2, Kevin Lieber explains the mathematical magic that enables mentalists to confound audiences by correctly guessing the number they've picked. Even though I know how it's done, it still confounds me.
The great Katherine Johnson, one of the legendary African-American mathematicians who were essential to the Apollo 11 moon landing, has died at age 101. You'll recall that Johnson, who worked at NASA’s Flight Research Division for more than three decades, was the central character in the film Hidden Figures. From the New York Times:
Mrs. ... In this video on StandUpMaths, Matt explains the unique and rare palindromic qualities of the date 02/02/20. Besides being a palindrome in both US and European dating formats, 02/02/20 is also the 33rd day of the year, and because 2020 is a leap year, there are also 333 days left in the year.

Sure, you can count them. ...
Many pizza places offer special "deals" if you order two medium pies. You might think that two mediums deliver more cheesy goodness than one large pie, but usually you'd be mistaken. From Primer, a mathematical comparison of two 12" pizzas and one 18" pizza:
Area of two 12” pizzas:
12/2 = 6 6×6=36 ...
