Fidget spinners—the cool, new fad that everyone wants to get their hands on. It’s no doubt that this simple little toy has taken the world by storm, fascinating people by just spinning and spinning. Many people view the spinner, and similar fidget toys such as the Fidget Cube just as “toys”, but others use them for their intended purpose, which is supposedly to aid their concentration. So, does science prove or disprove this?
(Close to) 50 years after the death of Albert Einstein, I was hunched over my computer looking for a way to pass time, when I decided to acknowledge the crazy notions of a super genius. So here we go:
- Moving objects gain weight, shrink in size and experience time more slowly than a stationary object. Crazy, but follows logically from Einstein’s Special Theory of Relativity (STR). Not only have the three ideas above been proven mathematically, but also experimentally. Although, quite sadly, we can’t experience the effects of STR in our day-to-day lives, NASA needed Einstein’s wisdom to get to the moon.
- There is no way to know whether you are moving or simply stationary. This was enough to elicit the fury of physicists around the world. Silly as it sounds, it is again a logical idea. Ever look out the window of a moving train and ask yourself whether you are actually moving, or whether the background you observe is moving? Einstein did. And as a result of that nonsensical question, Einstein went on to assert that motion is relative. Only B can determine whether A is stationary or not. Moving on . . .
- Light is affected by gravity and can be bent. Or rather distorted by gravitational attraction. It was a solar eclipse that made Albert Einstein a scientific celebrity in less than 24 hours. His General Theory of Relativity (GTR) was proved when a very determined Englishman trekked to Africa to photograph and prove that during the solar eclipse light was distorted by 1.7 arcseconds, the precise predictions of GTR.
- We can make portals through space and time. No, it isn’t just science fiction. Einstein proved for the first time that we can in fact time travel if we produce a wormhole. This gave the inspiration for Christopher Nolan to make his film Interstellar. Wormholes can also be used for teleportation. It is believed to be a wormhole that Coraline crawled through to reach the “Other Universe”.
- The most famous equation ever. Also easily the most misinterpreted equation ever. Annoyingly, the mathematics used to obtain this equation is, according to the Heinemann Physics Textbook “outside the scope of this course”, but the equation itself is very simple. The total energy of an object is equal to the mass of the object when moving multiplied by the speed of light squared. When the object isn’t moving, the equation changes very slightly to , where is the “rest mass”.
However, as much as we can praise Einstein, he also made a widely publicised mistake. And then made another one. In fact, Einstein publicly rejected and completely abased a whole new branch of mind-bogglingly theoretical physics.
