There are apparently no shadows in these images. But they were taken during the brightest part of the day. This episode is brought to you by Squarespace: http://www.squarespace.com/physicsgirl There are only certain parts of the year and certain times of day when you can experience the subsolar point or Lahaina noon. There appears to be no shadow because the sun is directly overhead. This phenomenon happens twice a year for latitudes between the tropic of cancer and the tropic of capricorn at solar noon, when the sun is highest in the sky. But you have to be in the right place at...

Are perpetual motion machines possible?

A wheel that spins forever; a bird that never quenches its thirst; a clock that never stops ticking, an endless source of free energy. These are but the dreams of inventors striving to make perpetual motion machines, machines that can work forever without any energy input.

What is Water Hammer?

First 100 people to sign up will get $30 off their first Blue Apron order here: http://cook.ba/2hkRvlY. This video is sponsored by Blue Apron. Hydraulic transients (also known as water hammer) can seem innocuous in a residential setting, but these spikes in pressure can cause major damage to large pipelines and industrial pipe networks. In this video, we briefly discuss how water hammer occurs and how engineers mitigate the effect. -Patreon: http://patreon.com/PracticalEngineering -Website: http://practical.engineering Marxist Arrow by Twin Musicom is licensed under a Creative Commons Attribution License Source: https://www.youtube.com/watch?v=rBlLC8TUXP0 Tonic and Energy by Elexive is licensed under a Creative Commons Attribution License

Why Do Venomous Animals Live In Warm Climates?

Subscribe to Veritasium - it's free! http://bit.ly/YSWpWm As a Canadian-Australian, I have always wondered why it is that Australia has so many venomous animals that can kill you while Canada has virtually none. But it's not just Australia - it seems like all beautiful, warm places are cursed with venomous native species. So I set out to find the truth: why have all these venomous species evolved in the world's best holiday destinations? I asked chemists, visited the zoo, interviewed entomologists and snake experts. The answer I found was complicated: 1. The majority of venomous species are ectotherms, cold-blooded creatures whose internal temperatures...

The Ultraviolet Catastrophe

How did the field of quantum mechanics come about in the first place? The Rayleigh-Jeans catastrophe, also known as the ultraviolet catastrophe was a prediction by the Rayleigh-Jeans law that a blackbody would radiate infinite amounts of ultraviolet light. It wasn’t until Max Planck came along and predicted that light came in packets or quanta that the field of quantum mechanics emerged and unintentionally solved the ultraviolet catastrophe.

World's Roundest Object!

The world's roundest object helps solve the longest running problem in measurement -- how to define the kilogram. Support Veritasium on Patreon: http://bit.ly/VePatreon A kilogram isn't what it used to be. Literally. The original name for it was the 'grave', proposed in 1793 but it fell victim to the French Revolution like its creator, Lavoisier. So begins the tale of the most unusual SI unit. The kilogram is the only base unit with a prefix in its name, and the only one still defined by a physical artifact, the international prototype kilogram or IPK. But the problem with this definition has long been...

For the Love of Physics (Walter Lewin's Last Lecture)

On May 16, 2011, Professor of Physics Emeritus Walter Lewin returned to MIT lecture hall 26-100 for a physics talk and book signing, complete with some of his most famous physics demonstrations to celebrate the publication of his new book For The Love Of Physics: From the End of the Rainbow to the Edge of Time - A Journey Through the Wonders of Physics, written with Warren Goldstein. Note: Due to a serious complaint against Dr. Lewin, MIT has revoked Dr. Lewin's title of Professor Emeritus as of December 2014. See https://newsoffice.mit.edu/2014/lewin-courses-removed-1208 and http://tech.mit.edu/V134/N60/walterlewin.html. This video was formerly hosted on the YouTube channel...
