Moonwalk and 9/11 photographs part of ‘global visual memory’

Results of 12-nation survey show that some iconic images are better known than others From the spacesuit-clad form of Buzz Aldrin on the moon to the middle-distance gaze of Che Guevara, some photographs really are seared into the publics mind all over the world, research suggests. While some images have long been hailed as iconic, experts say there has been little research to show that certain photographs are widely recognised and what people read into them. An international study by a researcher in the Netherlands set out to examine just…

Why You Always Wear a Hard Hat on a Construction Site

If you value your brain/head/life, wear a hard hat on any active work site. It protects your noggin from: fixed objects and equipment, falls, and it also stands out. Hard hats also protect you from falling objects, which as this video eloquently demonstrates, can be disastrous if you’re not protected. Just look at the difference a mere 10 ft makes on the force of impact from just a 1 pound object. Read more: https://twistedsifter.com/videos/always-wear-a-hard-hat-on-a-construction-site/

Why Are 96,000,000 Black Balls On This Reservoir?

Veritasium took a boat through 96 million black plastic balls on the Los Angeles reservoir to find out why they’re there. The first time he heard about shade balls the claim was they reduce evaporation. But it turns out this isn’t the reason they were introduced. The balls are made of high density polyethylene (HDPE) which is less dense than water so they float on the surface of the reservoir even if they break apart. They are 10cm (4 inches) in diameter and contain about 210ml of water. So the…

The Odd Physics of Rey’s Backflip in Star Wars: Episode IX

The vertical acceleration. On Earth, this is -9.8 m/s2. The distance scale. How many pixels of video in one meter of distance? The time scale. What is the length of time for each frame? If you know two of these three things, you can find the third. Here you can see there is a problem. I'm pretty sure I can get a distance scale by using the height of Rey (or the size of the TIE fighter). But what about the other two? It seems I should stay away from…

The Incredible Teamwork Behind the First Ever Image of a Black Hole

EHT Collaboration In coordinated press conferences across the globe, EHT (Event Horizon Telescope) researchers unveiled the first direct visual evidence of a supermassive black hole and its shadow. The image reveals the black hole at the centre of Messier 87, a massive galaxy in the nearby Virgo galaxy cluster. This black hole resides 55 million light-years from Earth and has a mass 6.5 billion times that of the Sun. Messier 87 Messier 87 The Event Horizon Telescope (EHT) is a planet-scale array of eight ground-based radio telescopes forged through international…

Prep for Your Toughest Races Like a Master Marathoner

On Wednesday, I spoke with Mebrahtom Keflezighi, perhaps the most successful American marathoner of all time. He won the New York City marathon in 2009 and the Boston Marathon in 2014. He won an Olympic silver medal and was internationally competitive until the age of 42, in a sport where people tend to peak much younger than that. On Monday, he will be the grand marshall of the Boston Marathon. Keflezighi possesses a wealth of running wisdom, much of which he shares in his book 26 Marathons. We spoke mainly…

Researchers Want to Link Your Genes and IncomeShould They?

The UK Biobank is the single largest public genetic repository in the world, with samples of the genetic blueprints of half a million Brits standing by for scientific study. But when David Hill, a statistical geneticist at the University of Edinburgh, went poring through that data, he wasn’t looking for a cure for cancer or deeper insights into the biology of aging. Nothing like that. He was trying to figure out why some people make more money than others. Along with a team of European collaborators, Hill sifted through the…

What makes somebody change their mind about Brexit? | Andre Spicer

Leading Brexiter voice Peter Oborne has done a U-turn, showing that even locked-in beliefs have a tipping point, says professor of organisational behaviour Andr Spicer Its nearly three years since I, along with 17. 4 million other Britons, voted for Brexit. Today I have to admit that the Brexit project has gone sour. So began the Daily Mail columnist Peter Obornes widely shared piece on why he Leon Festinger and his colleagues.

How hermit crabs shake off competitors for shells

House hunters are deterred from evicting incumbents by strong vibrations from inside Hermit crabs shake in their shells to ward off competitors who have designs on their homes, scientists have found. Field tests conducted on a beach in Costa Rica showed Pacific hermit crabs are swiftly deterred from ousting an incumbent when they sense strong vibrations coming from inside. Researchers at Dartmouth College in New Hampshire set out to investigate the role of vibrations after noticing that the land-dwelling crabs performed a shunting motion when others climbed on their backs.…

Deep Learning Smart Paintbrush Turns Doodles Into Photorealistic Images

A deep learning AI model developed by NVIDIA Research has been seen turning rough doodles into photorealistic images with astonishing ease. The tool leverages generative adversarial networks, or GANs, to convert segmentation maps into lifelike images. The interactive app using the model, in a lighthearted nod to the post-Impressionist painter, has been christened GauGAN. Post-Impressionist Paul Gauguin GauGAN could offer a powerful tool for creating virtual worlds to everyone from architects and urban planners to landscape designers and game developers. With an AI that understands how the real world looks,…
