A great day for invention

April 25 has historically been a great day for invention. On this day in history, Watson and Crick published the landmark research paper that described the double helical structure of DNA.

Also on April 25, Bell Telephone demonstrated the first practical solar cell. And on another April 25, the first U.S. patent was granted for an integrated circuit.

And it also was on an April 25 that a submarine, for the first time, managed to travel all the way around the Earth underwater. And on yet another April 25, for the first time ever, a human-made object wandered out of our Solar System to enter into the great beyond.

To me, all of this makes April 25 a very auspicious day for human invention. I would like to think that on some future April 25, somebody who is reading this will invent something profound and beautiful.
