Temperature is a measure of the average energy of the particles that make up a substance. It relates to the idea of hotness and coldness. If an object feels hotter, generally it has the higher temperature.
In this playlist, you will see some of the coolest experiments related to temperature.
Learn how nanotechnology combined with genetic engineering and computerized artificial intelligence may allow people to choose their feelings, increase their intelligence, or lengthen their life spans.
Everything we can see in the night time sky is made of nuclear matter. Nuclear physics describes how the Sun generates the energy we need for life on Earth, how all the atoms in your body were made in stars and what happens in stars when they die.
Learn how the different elements of the universe were formed, with this complete guide.
Until the Cassini mission, little was known about Saturn’s largest moon Titan, save that it was a Mercury-sized world whose surface was veiled beneath a thick, nitrogen-rich atmosphere. But Cassini mapped Titan’s surface, studied its atmospheric reactions, discovered liquid seas there and even sent a probe to the moon’s surface, completely rewriting our understanding of this remarkably Earth-like world.
The Science Behind the Bike is a series of films that investigate how science and technology have transformed the sport of cycling. We talk to Olympic gold-medallists Chris Boardman and Rebecca Romero, and Paralympian gold-medallist Sarah Storey, take a trip to a wind tunnel, consult with Team GB physiologists and hear from design experts and cycling legends such as Graeme Obree and Francesco Moser. In this series you will find out about the legendary Hour Record (the record for the longest distance cycled in one hour), learn about technology, discover the forces that have to be overcome to ride fast and understand how the body deals physiologically when riding at Olympic level.
This is a complete guide about how tu build your own Go Kart.
The first thing you need to do, is make a design. You have to design everything for it to work out in the end. First is to design the frame. How big is it going to be, how wide? Draw it on a sheet of copy paper first and think of how long you want it. Figure out all of the dimensions and angles in it. Next, transfer the small drawing on to a big sheet of paper so that it will be the exact size that the frame will turn out to be.
Environmental science is an interdisciplinary academic field that integrates physical, biological and information sciences to the study of the environment. Watch these video lessons, and learn about the different aspects of environmental science.
While physical techniques currently play a leading role in these discoveries, the chemistry of superheavy elements is now beginning to be developed. We show in these awesome videos how six elements on the periodic table were created and meet the man who helped do it.
The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage.
He designed the Analytical Engine and it was this design that the basic framework of the computers of today are based on.
