The Calculator That Helped Land Men on the Moon

Introduced at a Business Equipment Manufacturers Association show in New York in October 1965, this programmable desktop calculator provedan immediate success. Also known as the P101 or the Perottina (after the chief engineer who designed it, Pier Giorgio Perotto), it eventually sold more than 40,000 units, primarily in the United States but also in Europe.

Atom Power Is Launching the Era of Digital Circuit Breakers

Circuit breakers have been mechanical switches for 140 years. Now Atom Power is launching the first UL safety-certified digital circuit breaker panel combined with smart software and connectivity that could help monitor and control energy use of buildings remotely. In the dark, dank depths of your home basement hangs a drab gray box that guards […]

First sun-dimming experiment will test a way to cool Earth

Researchers plan to spray sunlight-reflecting particles into the stratosphere, an approach that could ultimately be used to quickly lower the planet’s temperature. Zhen Dai holds up a small glass tube coated with a white powder: calcium carbonate, a ubiquitous compound used in everything from paper and cement to toothpaste and cake mixes. Plop a tablet […]

Researchers discover a novel method to block immunosuppression in cancer

Belgian research groups from the UCLouvain and WELBIO, VIB and Ghent University, and the biotechnology company argenx elucidated the three-dimensional structure of an assembly of proteins operating on cells that dampen immune responses. They also discovered how an antibody can block this assembly and the immunosuppression it induces downstream. Such an antibody could serve to […]

UBC breakthrough opens door to $100 ultrasound machine

Engineers at the University of British Columbia have developed a new ultrasound transducer, or probe, that could dramatically lower the cost of ultrasound scanners to as little as $100. Their patent-pending innovation—no bigger than a Band-Aid—is portable, wearable and can be powered by a smartphone. Conventional ultrasound scanners use piezoelectric crystals to create images of […]

Physics Needs Philosophy. Philosophy Needs Physics

Contrary to claims about the irrelevance of philosophy for science, I argue that philosophy has had, and still has, far more influence on physics than is commonly assumed. I maintain that the current anti-philosophical ideology has had damaging effects on the fertility of science. I also suggest that recent important empirical results, such as the […]

The best representations of mathematics may not exist yet

Humility. It’s all I can feel after watching 3Blue1Brown’s latest maths video, in which Grant Sanderson and his team provide the most novel of approaches to solving 2D equations, using colour. It is the second time 3Blue1Brown has blown my mind to pieces in just a few weeks, following their earlier video that solved the […]
