How Do You Do High Jump

An athlete uses physics to shatter world records Asaf BarYosef

In the early 1960s, Dick Fosbury tried his hand at almost every sport, but never excelled at anything, until, at the age of 16, he turned to the high jump. But when he couldn't compete against the strong athletes at his college using the standard high jump techniques of the time, Fosbury tried to jump a different way: backwards.

Instead of jumping with his face towards the bar, bringing each leg over in the traditional straddle method, he jumped with his back towards the bar. Fosbury improved his record by over half a foot, and left his coaches amazed by this strange new style of high jumping. During the next few years,

Fosbury perfected his high jump style, won the U.S. National trials, and assured his place in the 1968 Olympics in Mexico. In the Olympic Games, Fosbury amazed the world with his new technique, winning a gold metal with an Olympic record leap of 2.24 meters. By the next Olympic Games, almost all of the competing of high jumpers

had adopted what came to be known as the Fosbury Flop. What's the secret behind the techniqueé It lies in a physics concept called the center of mass. For every object, we can locate the average position of all of its mass by taking into account how the mass

is spread around the object. For instance, the center of mass of a flat, rectangular object of uniform density will be in the intersection of both diagonals, in equal distance from each corner. We can find the center of mass for other objects by similar calculations, or by finding the object's balancing point,

which lies right underneath its center of mass. Try balancing a broom by holding it and slowly bringing your hands together until they meet. This balancing point lies right underneath the broom's center of mass. We humans also have a center of mass. When most people stand up, their center of mass is around the belly,

Overwatch Genji Edge Boost Trick

A lesser known trick in Overwatch is the the Genji edge boost. It essentially catapults Genji across the map at a high speed by having him dash at a horizontal ledge. This tutorial will first cover a stepbystep, keypressbykeypress breakdown of the how to do the Genji edge boost techin Overwatch,

and then go on to the gameplay ramifications that it could have. Let's slow down the first clip we saw and take a look at the inputs we need to give to the game to pull it off. In this clip, we start out by double jumping, but this is not strictly necessary. It can be done from the ground.

Then, as our crosshair reaches the cornerof the ledge, we initiate Swift Strike by pressing Shift. Immediately after that, we press and hold the Forward Movement and Jump buttons. By default, W and Spacebar. One we reach the ledge, we let go of those buttons,

and if done right, we are launched forward and upward. If done incorrectly, we may hit the ledge and climb up to it, land on the ledge at the end of our dash, fall down to the ground, or even be launched backwards or at a weird trajectory.

The way Swift Strike normally works is that Genji's velocity is reset to zero at the end of the dash. This bug somehow stops that from happening, and he retains his momentum. Oddly, the game doesn't recognize this as a wall climb, either which means you can immediately wall climb

after using the edge boost without needing to touch the ground. So that's how you do it. If you're having trouble, just ask and I'll do my best to answer, but don't bother spending hours trying tolearn this. It's likely to be patched out by Blizzard. Back when Overwatch was in beta,
