A global exploration of the past, present and future of technology and science as applied to Olympic sports and athletes. These running prosthetics are capable of recreating the movements of a Paralympian's joints to perfection.
Stephen Hawking, the brilliant British theoretical physicist who overcame a debilitating disease to publish wildly popular books probing the mysteries of the universe, has died, according to a family spokesman. He was 76.
Chewang Norphel, a 79 years old civil engineer from Ladakh, India, started building dams, or artificial glaciers, out of ice, 30 years ago, in order to efficiently use the water gathered from melting ice in the Himalayas. People call him Ice Man for his true inspiration for innovations in water conversation.
The ratio of a circle's circumference to its diameter is always the same: 3.14159... and on & on forever. This irrational number, pi, has an infinite number of digits. Lets figure out pi's vast applications to the study of music, financial models, and even the density of the universe.
David Thouless, Duncan Haldane, and Michael Kosterlitz won the Nobel Prize in Physics in 2016 for discovering that even microscopic matter at the smallest scale can exhibit macroscopic properties and phases that are topological. Watch this video to decode some seriously tricky science.
Learn the basics of Python from CS50. Python is a general-purpose interpreted, interactive, object-oriented, and high-level programming language. Harvard University's introduction to the intellectual enterprises of computer science and the art of programming. CS50 is the quintessential Harvard (and Yale!) course.
This homemade speaker uses a toy motor insteadof a coil of wire and a magnet.The amplifier wires are simply attached to a toy motor to make it vibrate. Use it to make a conductor speaker that only you can hear or attach it to a paper plate to make a simple speaker that will amplify the sound.
The rollback toy idea is put to the test to see how far we can get it to travel when powered by just 3 rubber bands. It is a great example of changing potential mechanical energy into kinetic motion energy. Fine tuning and given a long and wide enough area, this roll back toy has the potential to go 200 feet or more.
These devices are sometimes referred to as solar motors or thermal motors, or even thermal retraction motors. Sunlight hitting the strips is converted into thermal energy (heat) which then causes the rotor to turn without any electrical or other mechanical parts.
