Sesame Street: What is a Computer? 1984

What makes a computer different from a person? A computer doesn't have bones.

Smart children are interviewed about computers in the 1984 episode of Sesame Street.


Watch Apple Lay into IBM Over the Years

Apple and IBM announced a sweeping deal to promote iOS in the enterprise this week, but the relationship hasn't always been so cozy. Watch as Cupertino gives IBM a hard time over and over (and over) again.


How Gravity Makes Things Fall

A new demonstration of gravity, featuring the "Spacetime Stretcher," built mostly out of materials from my garage and the hardware store. More info:

1. As a falling object's path goes increasingly in the space (down) direction, it goes a little bit less in the time direction. Gravity is effectively converting some of its travel through time into travel through space. How much time converts into how much space? It works out to be 186,000 miles of space for every second of time -- that's the speed of light! The equivalence between a little time and a lot of space has a parallel with Einstein's famous equation E = mc^2, where a little mass is equivalent to a lot of energy -- also with the speed of light c as the conversion factor, only squared. It's amazing how all these physics concepts fit together.

2. An object moving up or down at the speed of light, such as a photon, follows a vertical path on our graph. If we could warp the Spacetime Stretcher as much as we wanted, we could make the time axis curve around and re-intersect with this vertical line. That would be a black hole: Even a photon moving straight up would get "warped back" to the place where it started.

3. Spacetime warping is usually depicted as going into a higher dimension -- in this case, bending toward or away from the camera. But such a device would have been much harder to build. You can think of this model as a two-dimensional "projection" or "shadow" of three-dimensional curvature, i.e. the flattening of a flared-out surface that curls away from the plane of the graph.

4. In addition to mechanically calculating trajectories of objects falling on the Earth, Mars, or Moon, the Spacetime Stretcher (at a zoomed-out calibration scale) can also calculate the length-contraction and time-dilation observed with a rocket traveling close to the speed of light.

Jim Carrey's Commencement Address at the 2014 MUM Graduation

Maharishi University of Management (http://www.mum.edu) granted degrees to 285 students representing 54 countries. Jim Carrey gave the commencement address to Maharishi University of Management's class of 2014. The University Board of Trustees also presented Mr. Carrey with the honorary degree of Doctor of Fine Arts Honoris Causa, in recognition of his significant lifetime achievements as a world-renowned comedian and actor, artist, author and philanthropist.


UEV 440 Off Road Camper Trailer

Toby Bosschieter takes us through the UEV 440 from Conqueror Australia. This model shares many of the same components and design principles as its bigger brother the UEV 490. The UEV 440 has a hard roof, sides and floor and nothing that folds out to touch the ground. It is built to handle the toughest off-road conditions - allowing you to explore remote Australia in comfort.

For more information on the UEV 440 go to www.UEV.com.au


300 Feet to the Moon

After making the 240,000-mile journey to the moon cruising through open space, the last 300 feet down to landing represented the most difficult and dangerous part of the Apollo missions. The Apollo astronauts needed a way to practice that final descent and landing before Apollo 11 astronauts Neil Armstrong and Edwin "Buzz" Aldrin made the first historic moon landing in their lunar lander named Eagle on July 20, 1969.
