¿Cuán lejos puede llegar una pelota de baloncesto girando hacia atrás, si la dejas caer desde una gran altura?

Descubran las increíbles aplicaciones del efecto Magnus, tanto en el área de la aviación como en la naval.

Incluso podemos verlo actuar en aquellos deportes que se practican con una pelota.

Compré 10,000 bolas de sombra e intenté nadar en ellas. Parecen actuar como un fluido no newtoniano: se comportan rígidamente bajo un alto esfuerzo cortante, pero fluyen como un líquido si se lo somete a un bajo esfuerzo cortante.

Mi sensación era que nadar en bolas de sombra sería difícil pero no imposible. Esto fue más o menos cierto cuando lo intenté con una sola capa de bolas de sombra. Las bolas de sombra se deslizan entre sí, entonces actúan como un líquido, aunque viscoso debido a su gran inercia. Es un ejercicio mucho más intenso y también es molesto ser bombardeado con bolas de sombra en todos los lados del cuerpo, especialmente en la cabeza.
Cuando probamos con múltiples capas de bolas de sombra (como están dispuestas en gran parte del embalse de Los Ángeles) las cosas se vuelven significativamente más difíciles. Las bolas se juntan y cuando intentas moverte rápidamente, se vuelven más rígidas, proporcionando una resistencia significativa al movimiento. Esto tiene el beneficio de que puedes acostarte sobre ellas y, siempre y cuando permanezcan atrapadas debajo tuyo, puedes flotar sobre ellas. Pero un poco de movimiento hace que se muevan y te hundas rápidamente.

Para recibir una bola de sombra:
1. Apoya Veritasium en cualquier nivel de Patreon e ingresa tu dirección: https://ve42.co/patreon
2. En aproximadamente un mes enviaré las bolas de sombra firmadas
3. Cubriré todos los costos de envío, pero si las cosas se salen de control, le daré prioridad a los partidarios de Patreon ya existentes y los de niveles más altos

Muchas gracias a:
Jordan Schnabel y Cristian Carretero por filmar, nadar y proporcionar servicios de guardavidas.
Raquel Nuno por filmar y por el apoyo.

Adiemus by Karl Jenkins, performed by the London Philharmonic Orchestra & sung by Miriam Stockley, featuring video clips from Final Fantasy X and interpretive dancing by Russian prima ballerina Anastasia Volochkova. Her video was first posted by post8890 on April 13, 2008, I believe, but was made most popular by the postings done by TUXINO100 (over half a million hits, despite mislabeling the artist as Enya), poganka (an excerpt with over one million hits), but most impressively posted by CheatingNoob (over 300,000 hits.) Many other postings exist as well.

Also plaidnchainschik first thought to post Final Fantasy vid clips to Adiemus (over 650,000 hits) which is where I got my inspiration to match up Final Fantasy X with Volochkova. When I first saw one and then the other, I was amazed at the similarity between the choreographies of both the dance and the video game. Even the colors of yellow and blue in both mediums are of a strikingly similar hue.

Anyway, I cleaned up the soundtrack (I hope) and straightened out the synchronization between Volochkova and the song (which was off in some spots.) I also had to extend the song a bit in order synch up the dance with the video game clips. I hope you like it!

And finally, thanks so many MANY times to NCH Software for VideoPad Video Editor. It is free, and it is awesome! Try it, you'll like it!

Thanks to Google Making and Science for helping me pursue my #sciencegoals. If you want to try this experiment, instructions are here: link.springer.com/article/10.1007/s12650-016-0383-5

The standard theory of quantum mechanics leaves a bit to be desired. As Richard Feynman put it, "I think I can safely say that no one understands quantum mechanics." This is because observations of experiments have led us to a theory that contradicts common sense. The wave function contains all the information that is knowable about a particle, yet it can only be used to calculate probabilities of where a particle will likely turn up. It can't give us an actual account of where the particle went or where it will be at some later time.

Some have suggested that this theory is incomplete. Maybe something is going on beneath the radar of standard quantum theory and somehow producing the appearance of randomness and uncertainty without actually being random or uncertain. Theories of this sort are called hidden variable theories because they propose entities that aren't observable. One such theory is pilot wave theory, first proposed by de Broglie, but later developed by Bohm. The idea here is that a particle oscillates, creating a wave. It then interacts with the wave and this complex interaction determines its motion.

Experiments using silicone oil droplets on a vibrating bath provide a remarkable physical realization of pilot wave theories. They give us a physical picture of what the quantum world might look like if this is what's going on - and this theory is still deterministic. The particle is never in two places at once and there is no randomness.

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 apparent. The IPK doesn't seem to maintain its mass compared to 40 similar cylinders minted at the same time. The goal is therefore to eliminate the kilogram's dependence on a physical object. Two main approaches are being considered to achieve this end: the Avogadro Project and the Watt Balance.

The Avogadro project aims to redefine Avogadro's constant (currently defined by the kilogram -- the number of atoms in 12 g of carbon-12) and reverse the relationship so that the kilogram is precisely specified by Avogadro's constant. This method required creating the most perfect sphere on Earth. It is made out of a single crystal of silicon 28 atoms. By carefully measuring the diameter, the volume can be precisely specified. Since the atom spacing of silicon is well known, the number of atoms in a sphere can be accurately calculated. This allows for a very precise determination of Avogadro's constant.

Special thanks to Katie Green, Dr. David Farrant, the CSIRO, and the National Measurment Institute for their help. Thanks also to Nessy Hill for filming and reviewing earlier drafts of this video.

There is debate as to whether this is truly the roundest object ever created. The Gravity Probe-B rotors are also spherical with very low tolerances such that they may in fact be rounder.

Jetpacking was awesome fun! Despite the fat lip I had a great time. I think knowing a bit about physics actually helps fly the jetpack. It works on the same principle as a rocket (Newton's 3rd law) but unlike the shuttle, you don't carry your own propellant with you. Instead, water is pumped out of the lake by the jetski at up to 60 litres a second. It is then fired out of the nozzles at around 15 m/s creating 1800 N of force, the equivalent of about 150 fire extinguishers. On me this can produce acceleration of about 1.5g's.
