Easy Graphical Multiplication Trick
http://www.livephysics.com/physics-videos/tools/easy-graphical-multiplication-trick.html
It's not a way to make mental multiplications easier, it's just a
funny way to resolve graphically a multiplication. It's only meant to
be a little trick to show to friends and kids who hate maths. It's NOT
meant to be efficient as some seems to think. You can do any kind of
multiplication with it but yes it's boring to draw numbers like 8 or
9.
Bitwise Operation
http://www.livephysics.com/ptools/bitwise-operation.php
In computer programming, a bitwise operation operates on one or two
bit patterns or binary numerals at the level of their individual bits.
On many computers, bitwise operations are slightly faster than
addition and subtraction operations and significantly faster than
multiplication and division operations.

On March 22, 2000, while in orbit 124 miles (200 kilometers) from
Eros, the NEAR Shoemaker spacecraft captured this rotation movie of
the asteroid's northern hemisphere. The movie features three of Eros'
major morphologic features under dynamically changing lighting
conditions.

Perceptive Pixel is a startup founded by Jeff Han. Working all but
alone from his hardware-strewn office, Jeff Han is about to change the
face of computing. Not even the big boys are likely to catch him. Jeff
Han and Phil Davidson shows how a multi-touch computer screen will
change the way we work.

Superconducting Magnetic Levitation Model Train from the IFW Dresden,
Germany. Magnetic levitation, maglev, or magnetic suspension is a
method by which an object is suspended above another object with no
support other than magnetic fields. The electromagnetic force is used
to counteract the effects of the gravitational force.
Time Fountain - Optical Illusion
http://www.livephysics.com/physics-videos/tools/time-fountain-optical-illusion.html
This device creates the illusion that a simple stream of water
droplets can defy the known laws of physics. By controlling a set of
flickering LEDs, the dripping water can appear to slow down, freeze in
mid-air, and even reverse in direction.
