Physics marble track review part one // Homemade Science with Bruce Yeany

track material is easy to work with and cheap. it is called shelf bracket tracks or shelf uprights. I have seen various hardware stores and building supply stores carry it, one company that makes it is Rubbermaid. E5 shelf upright. available at Home Depot, Last time I checked, Lowes does not carry it https://www.homedepot.com/p/Rubbermaid-E5-72-in-Zinc-Upright-FG4B9200ZINC/100177025 Introduction song. is an Apple jingle found in the iMovie media files, the title is called "catwalk, medium" For more information and explanations on any of the tracks demonstrated in this video, see the...

Bell's Theorem: The Quantum Venn Diagram Paradox

Featuring 3Blue1Brown Watch the 2nd video on 3Blue1Brown here: https://www.youtube.com/watch?v=MzRCDLre1b4 Support MinutePhysics on Patreon! http://www.patreon.com/minutephysics Link to Patreon Supporters: http://www.minutephysics.com/supporters/ This video is about Bell's Theorem, one of the most fascinating results in 20th century physics. Even though Albert Einstein (together with collaborators in the EPR Paradox paper) wanted to show that quantum mechanics must be incomplete because it was nonlocal (he didn't like "spooky action at a distance"), John Bell managed to prove that any local real hidden variable theory would have to satisfy certain simple statistical properties that quantum mechanical experiments (and the theory that describes them) violate. Since then, GHZ and...

Can Silence Actually Drive You Crazy?

*Watch with headphones on! Is 45 minutes really the longest anyone can stay in a perfectly silent, pitch-black room? Support Veritasium on Patreon http://bit.ly/VePatreon Check out Audible: http://bit.ly/AudibleVe Want to watch the whole hour of silence? http://youtu.be/jr1UMFC9DV0 Many stories have circulated claiming the longest anyone has stayed in an ultra-quiet anechoic chamber is 45 minutes, the reason being any longer would drive you insane. To me this sounded like unsubstantiated rubbish, like the claim the Great Wall is the only manmade structure visible from space. So I put my own psyche on the line, subjecting myself to over an hour of the most intense quiet...

A Beginner's Guide to the Fourth Dimension

Math can be weird sometimes, usually when it goes against some of our most common knowledge, yet still can make sense. This is one of those times.

Why Not Admit There is a Problem With Math and Music? Dan Formosa at TEDxDrexelU

NOTE FROM TED: We've flagged this talk, which was filmed at a TEDx event, because it appears to fall outside TEDx's curatorial guidelines for its assertions about math and music. TEDx events are independently organized by volunteers. The guidelines we give TEDx organizers are described in more detail here: http://storage.ted.com/tedx/manuals/tedx_content_guidelines.pdf Dan Formosa's work covers many areas of design. A unifying theme is the idea that great design requires that we first understand people. This talk is not a class in math or music. It's a discussion about challenges to understanding math and music, topics for which literacy rates are low. Both...

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...

Solving the IMPOSSIBLE LOTUS Puzzle!! LEVEL 10!

Today I'm going to attempt to solve this extremely challenging, level 10 Lotus Box puzzle! The object of the Lotus is to find the Lotus Flower. BUY PUZZLES HERE: http://bit.ly/2gcfgMe To do this you need to remove an aluminum circular disc with a rod running through the centre. But if you think you've done the puzzle by then you're very much mistaken. The Lotus is based on the Yen Puzzle which was invented by Wil back in 1979. That puzzle had a wooden frame with a nail in it that held a Japanese Yen Coin. This new puzzle is beautifully machined from anodised...

A mirror paradox, Klein bottles and Rubik's cubes

The Mathologer puts the latest $2000 addition to his Klein bottle collection to work. A couple of first-ever fun mathematical stunts in this video. This video finishes with a puzzle for you to think about. We posted a video with the solution on 1 August 2015: https://youtu.be/ZMC61C5tigA Enjoy! Burkard Polster and Giuseppe Geracitano P.S.: Most of of Burkard's glass Klein bottles as well as the Klein bottle hat were made by Cliff Stoll of ACME Klein bottles (www.kleinbottle.com). The metal 3d-printed Klein bottle opener was made by Bathsheba Grossman (www.bathsheba.com).

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...

Quantum Cooling to (Near) Absolute Zero

Getting down to liquid helium temperatures (4K) may be fairly straight forward, but cooling below that requires taking advantage of quantum phenomena. In this video Associate Professor Andrea Morello from the University of New South Wales explains how 'zero-point motion' makes it possible to use Helium-3 and Helium-4 in a dilution fridge to get down to only thousandths of degrees above absolute zero. It is this technique which is used to cool the MiniGrail at Leiden so that it can act as a gravitational wave antenna. For more on Dr. Morello, see: http://bit.ly/17wZ7lt

Impossible Ancient Pyramids That Prove Everything We Know Is Wrong

Almost everything they teach us about the ancient history is wrong: origin of men, civilizations, and pyramids. Our scientific instruments are simply not enough to explain the purpose of oldest pyramids, for example. Mainstream scientists, archaeologists, historians and anthropologists are often main obstacle for scientific progress. New dating of Peruvian, Mexican, Chinese and Egyptian pyramids will take us back much before recognized history and known rulers. Oldest Chinese and Egyptian pyramids are much superior to those made later as unsuccessful replicas. Older are built from granite and sandstone blocks, more recent ones are much smaller, built from bricks and mud....
