It’s the latest effort by the South Florida Water Management District to eliminate as many pythons are possible from the Everglades, where they are decimating native species.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Refraction—the bending of light as it passes through different media—has long been constrained by physical laws that prevent independent control over how light waves along different directions ...

Morse code is nearly 200 years old and can be used to quickly transmit messages locally or around the world, although there are better systems in use today.

Information could potentially be stored in ice for millennia, simply by making subtle changes to the shape and position of internal bubbles, which can then be converted into binary or Morse codes.

Assigning certain sizes, shapes and positions of bubbles to characters within Morse and binary codes means messages could be stored in ice ...

How Does Morse Code Work? Samuel Morse is to the telegraph what Thomas Edison is to the light bulb—he didn’t necessarily invent the technology, but he did perfect it.

Morse code is still used as a communication in the military and amateur radio organizations. To make it easier, we made a digital Morse code signaling device which works by using intermittent light.
