Officials at the 2018 Pyeonchang Winter Olympics have occurred that a cyber attack hit the games, taking its website as well as TV and internet access at its main press center offline, the Guardian reported.
This month in Pyeongchang, elite teams of physics and materials science experts from all over the world will dazzle us with ostentatious displays of grace and power. We commonly refer to these experts as athletes. Gymnasts demonstrate their subtle understanding of gravity and momentum. Swimmers and divers master fluid dynamics and surface tension. Skiers harness their knowledge of friction and hydrology, and lugers push their aerodynamics chops to the limits. Olympians, after all, understand science at a visceral level in ways most of us don’t.
Remember the feelings of thrill and terror when you launched your sled down a steep snow-covered hill? American Skeleton racer John Daly has been doing that competitively for 15 years, but his sled, which slides down an ice-covered bobsled using a pair of metal runners, can actually hit speeds of up to 90 miles per hour.
THE SPEED SKATING suit has always been the technical marvel of the Winter Olympics. With high-tech fabrics and unusual construction, it’s designed to eek out every bit of athletic optimization. In a sport where a thousandth of a second can determine who gets a medal and who doesn’t, athletes rely on technology to give them an edge. “We’re trying to get the body to be more aerodynamic than it is in its natural state,” says Clay Dean, chief innovation officer at Under Armour, the company behind the suit the US speed skating team will wear in PyeongChang this February.
Usain Bolt lives up to his surname ever time he steps onto a track. He loves to brag about being the fastest man on the planet, whether cameras are focusing on him or not. Whenever the Jamaican sprinter sets his feet into the block, it’s not uncommon to witness this guy make history in track and field.
ZOOM IN ON the details of just about any Olympic event and you can find some cool physics. Today, let’s look at the arrow in archery. It seems so simple: fletching, a shaft, and a point. It’s basically a sharp stick with some feathers. But if you watch an arrow fly in slow motion, you see something cool:
