Your brain replaces the blurry images with static images of your next object of focus. Whatever you look at after moving your eyes appears to stay still for a long period of time, because it is actually the same image stretched for a longer period of time to cover up the blur. This is called the "stopped-clock illusion", when the first second on a clock after you turn to look at it appears to take longer than all the other seconds.

The new technology developed by a team of scientists from the Laboratory for complex flow and heat transfer from the Institute of Technology in Harbin, made it easier for submarines and torpedoes to move under water extremely high speeds, according to the portal.
Lifang Chen, professor of mechanics and engineering fluid, said the innovative approach of this team, caused that they can now create complicated air "bubble" necessary to move quickly under water.
"We are very excited about the potential that it brings" he said, adding that there are still many unknowns to be solved.
Water causes more friction and resistance to movement than air, which means that ordinary submarines can not move as fast as an airplane, according to the portal.
Recalls that during the Cold War, the Soviet military developed a technology called super-cavitation, which included a "package" submarine inside air bubbles to avoid problems caused by water resistance.

The Soviet super-cavitation torpedo called Šakval able to reach the speed of 370 km / h or more, which was much faster than any ordinary torpedo.
In theory, the super-cavitational vessel could, under the water reaches the speed of sound, or about 5,800 km / h, which, according to the report of California Institute of Technology in 2001, could lead to reduced travel time from one to the other shore of the Atlantic Ocean to less than hour, while traveling from one to the other shore of the Pacific ocean took about a hundred minutes.
This is for now only in theory, scientists are skeptical of the practice.
In addition to Russia, the development of vessels and weapons based on super-cavitation technology deal with countries like Germany, Iran and the United States, according to the portal.

Some minor revelations have surfaced, however. At first, physicists thought friction was to blame, but in the late 1980s, they discovered that a sound wave’s path expanded bubbles and heated the gas inside them to temperatures hotter than the sun’s surface. That collapse with the heat, they thought, created a glowing plasma. Thirty years later, that is still the going theory.
However, researchers have suggested that different physical mechanisms must be at work and that there must be multiple kinds of sonoluminescence. What’s been concretely determined so far, though, is that it has to do with the size of the bubble as well as the OH emission from the bubble when it bursts.
If the science goes much further, it could be possible that some day sound and gas could be used to light underwater areas, exceeding the limitations of conventional lights.
