Occupational Arrows of Time

One of the subjects of great debate in physics goes under the moniker of “the arrow of time.” The basic debate here is (very) roughly to try to understand why time goes it’s merry way seemingly in one direction, especially given that the many of the laws of physics appear to behave the same going backwards as forwards in time. But aren’t we forgetting our most basic science when we debate at great philosophical lengths about the arrow of time? Aren’t we forgetting about…experiment? Here, for your pleasure, then, are some of my personal observations about the direction of time which I’ve observed over my short life. Real observation about the direction of time should lead us to the real direction of time, no?

Transatlantic Communication of a Different Kind

The telectroscope:

Hardly anyone knows that a secret tunnel runs deep beneath the Atlantic Ocean. In May 2008, more than a century after it was begun, the tunnel will finally be completed. Immediately afterwards, an extraordinary optical device called a Telectroscope will be installed at both ends which will miraculously allow people to see right through the Earth from London to New York and vice versa.
