A few months ago, physicists Cal Tech were able to bend visible light around an object and reform it on the other side rendering the object literally invisible, which is something that was thought to be impossible two years ago. Whether or not they can make that work for something as large as a human body is something else entirely. Other physicists have even been able to transport (as in Star Trek transport)particles from one side of the Danube River to another. Within a decade, they might be able to transport particles to the moon. And then maybe viruses or even water molecules. Who knows how soon Instant Transportion becomes reality.
I have an anecdote of my own about Tetris. I load airplanes at Fedex's World Hub. One of the smallest airplanes we use is a Boeing 727. The lower level of the plane, the bellies, is resticted to individual packages. Most nights, the weight shack sends out a shit load of boxes to put into the bellies. Doing so requires skill in what is known as T-stacking, the same stacking process that brick-layers use to cover houses. Anyway, whenever I become unfortunate enough to have to stack boxes, I start playing Tetris in my head and start humming the tune. It helps me get everything in and under the red line, which is a requirement by the FAA that states that no boxes can be placed above the red line that marks the top two inches of the compartment. In order to allow room for fire suppressants to reach the entire compartment. Which doesn't really make any sense since anything that is a fire hazard is considered Hazardous Materials and placed in a Haz-Can in the Upper Compartment. But then again, boxes are sometimes miss-labeled by the sender. I think that happened once. Some idiot sent a package that caught on fire, ruining all of the other packages in that particular container. They had to land the plane prematurely and everything was late. That cost us a lot of money.
