Destin from Smarter Every Day examines the jumping ability of grasshoppers and challenges us all to do a little math.
Magnets are amazingly strong… but there’s a very easy way to destroy them. All you need to know is a little bit about ferromagnetism, paramagnetism, and temperature!
At the heart of quantum mechanics is a mysterious equation known as the wave function. It helps explain the behavior of elementary particles, but also challenges the notion that there’s only one reality.
Earth’s radiation belts consist of energetic particles that are encircle the planet and are trapped by the geomagnetic field. The radiation belts usually form a two-zone structure, but last February, a team of scientists reported the surprising discovery of a previously unknown third radiation ring, which just now has been explained.
Uncrackable quantum encryption codes could be finding their way to mainstream networks. The new system, developed by Toshiba’s Cambridge Research Laboratory, allows dozens of users to share one network. Usually, each computer has to have an expensive and complicated transmitter and detector, as well as a fibre link. The networks work by transferring single photons of light in a sequence. If they’re observed en route, they change, making the code uncrackable in the laws of physics.
Sometimes, Earth mimics a supernova, producing a Terrestrial Gamma-ray Flash from the tops of thunderstorms. A new lightning sensor on the International Space Station could solve the mystery of these energetic bursts.
The etymology of the word magnet likely comes from naturally occurring lodestones (naturally occurring mineral deposits with magnetic properties) found by the ancient Greeks around the city of Magnesia. Likely thought of as witchcraft at the time, we now know that magnetism itself is due to unpaired electrons at a sub atomic level.
How do you know what you’re seeing is real? These Illusions bring about the truth!
Discover the scientific principles of the Boomerang.
Hank revisits his passion for exploring the Red Planet, breaking down the two biggest challenges of sending humans to Mars: radiation and propulsion. He explains the science behind the obstacles future Mars-bound astronauts will face, as well as they technology they’ll have to use to surmount them. Onward!
Discover the scientific nature of fire.
Most science projects are geared towards helping mankind, but these projects are particularly long-term, and their immense forethought and vision are targeted towards helping future generations.
What would life be like with just two (or four) dimensions?
One of the most significant scientific discoveries of the early 21st century is surely the Higgs boson, but the boson and the Higgs Field that allows for that magic particle are extremely difficult to grasp. Don Lincoln outlines an analogy that all of us can appreciate, starring a large dinner party, a raucous group of physicists, and Peter Higgs himself.
