Brake Test

Lauri Vuohensilta of the Hydraulic Press Channel drove the brakes of a 1990 Ford Fiesta until they exploded and filmed it with high-speed and thermal cameras for his other channel, Beyond the Press. Why? Because science.

As part of the Royal Institution‘s annual science-themed advent calendar they shared a stylized animation that explains physicist Richard Feynman‘s classic building block analogy for the first law of thermodynamics to explain the conservation of energy. Professor Andrea Sella recalls Feynman’s illustration of the first law of thermodynamics with a child’s building blocks and wily mother.

Up to half of of people who freeze to death are found partially or completely naked. DNews looks into the phenomenon of paradoxical undressing. New Scientist writes that “Between 20 and 50 per cent of deaths from hypothermia involve paradoxical undressing of some kind. Mountain rescuers are trained to expect it.”

Secrets of the Ocean Floor

Continental drift is common knowledge now, but when the idea was first proposed it was revolutionary. The maps of one of history’s finest cartographers shifted our view of the planet.

Mathematician and author Joseph Mazur breaks down the odds of a seemingly impossible coincidence in an insightful interview. Edwards explains the story of Anne Parish, a woman from Colorado Springs who found the exact copy of a book she owned as a child while on a trip to Paris. On its surface, Parish’s story sounds like it involves an inconceivable level of chance, but Mazur dug deeper and calculated the actual odds.

This video by Life Noggin explains what humans might expect when the Earth’s magnetic poles eventually reverse. It also covers the science behind what generates the Earth’s magnetic field.

The Illusion of Time

This video is from the documentary “The Fabric of The Cosmos.” Einstein’s mathematical theory of relativity (which has been tested with atomic clocks) tells us that the future and past always exist like the present.
