I took a boat through 96 million black plastic balls on the Los Angeles reservoir to find out why they're there. The first time I heard about shade balls the claim was they reduce evaporation. But it turns out this isn't the reason they were introduced.

Huge thanks to LADWP for arranging this special tour for me. Next time let's put the GoPro on the submersible!

The balls are made of high density polyethylene (HDPE) which is less dense than water so they float on the surface of the reservoir even if they break apart. They are 10cm (4 inches) in diameter and contain about 210ml of water. So the main reason they are on the reservoir is to block sunlight from entering the water and triggering a chemical reaction that turns harmless bromide into carcinogenic bromate. This effect occurs with prolonged exposure to bromate so regulators insist that levels be kept below 10 microgram per liter on average over a 12 month period.

This video is sponsored by Mercedes-Benz, who invited me to come to Stuttgart to see their latest cars, crash test facilities and experience the innovations they are working on.

Physics is something that is directly applicable to car safety. Cars go fast, but they also sometimes collide with obstacles, which brings them to a sudden stop, subjecting the car and occupants to very high accelerations, which can cause injury or death. So the major idea to improve car safety is to reduce these accelerations and there are a number of ways to do this:

Passive safety:

Seat belts: keep passengers in the vehicle, preventing them from continuing with constant velocity, flying through the windshield and suffering a worse deceleration when they make contact with the road.

Crumple zones: increase the distance over which deceleration occurs, thereby reducing peak magnitude of deceleration.

Air bags: increase the distance over which the head decelerates, again reducing peak magnitude of deceleration of the head.

Active Safety:
Anti-lock braking system: rather than 'locking' the wheels as can happen if you slam on the brakes with a traditional braking system leading to the tires skidding across the road, ABS attempts to control the amount of braking so that the tires always roll with static friction in contact with the road. This increases the backward frictional force that can be applied to the tires, again increasing the distance over which deceleration occurs, and it gives the driver an opportunity to steer to avoid the collision (hence why it's referred to as an active safety system).

Special thanks to Mercedes for having me visit facilities in Stuttgart. I had a lot of fun making these videos so please do check out the series on Mercedes Benz's channel: http://ve42.co/MB

Can we really touch things? Well if by touch we mean exchange a force-carrying particle with, then yes. The photon is the force-carrier of the electromagnetic interaction. But if the photon is also a particle of light then why aren't magnets glowing? Because the photons are virtual particles, which means they can't be directly detected (without changing the outcome we are trying to measure.

A quote by Einstein: A human being is a part of the whole, called by us "Universe", a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest — a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty. Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security.

Everyone has played with a mixture of corn starch and water (or at least I hope they have). This was one of my favorite experiments as a kid. Your hand slides into the slime easily when moving slowly but the mixture behaves as a solid if you hit it quickly. That is what is meant by 'non-Newtonian' - the fluid's properties change depending on its relative motion. These properties can be exploited to dramatic effect as has been shown on speaker cones before. Here I wanted to understand what is going on, what frequencies and amplitudes work best so I used a slow-mo camera.

Thanks to everyone at the YouTube Space LA for helping me film this. I couldn't have done it without you.

Innovative research conducted in Lausanne, Switzerland has shown that a combination of neurotransmitters and electrical stimulation can restore movement to the lower limbs of previously paralysed rats. But in order for this motion to be made voluntarily the rats must be motivated to walk. This motivation comes in the form of cheering, visual cues, and of course, chocolate.

If the sun were entirely made of protons, how many would there be in the sun? How can this be worked out using the Google search field?

At the jumper's fastest point, the acceleration is by definition zero. That is because the jumper is going from speeding up to slowing down. At this instant then there is no change in the jumper's velocity. This is counter-intuitive for a lot of people because it's easy to confuse velocity with acceleration. Velocity is how fast something goes while acceleration is the rate at which velocity changes.

NASA's Parker Solar Probe mission has returned unprecedented data from near the Sun, culminating in new discoveries published on Dec. 4, 2019, in the journal Nature. Among the findings are new understandings of how the Sun's constant outflow of material, the solar wind, behaves. Seen near Earth -- where it can interact with our planet's natural magnetic field and cause space weather effects that interfere with technology -- the solar wind appears to be a relatively uniform flow of plasma. But Parker Solar Probe's observations reveal a complicated, active system not seen from Earth.

LETRA:

ENAMORA'O
Daniel Calveti

De todas las boricuas, tú eres la más bella
el coquí lo canta al son de las maracas
el viento y las palmeras bailan mientras miran como tú y yo caminamos por la playa.

Mujer hermosa, mujer tan linda mis ojos son de ti solita. De Ponce a Caguas lo saben
todos que este negrito a ti te ama.

Ay, ay que lindo, que lindo estar enamorado

Ay, ay que lindo, que lindo estar enamorado

De todas las boricuas, tú eres la más bella
el coquí lo canta al son de las maracas
el viento y las palmeras bailan mientras miran como tú y yo caminamos por la playa.

Mujer hermosa, mujer tan linda mis ojos son de ti solita.
El flamboyant se ha convertido en nuestra sombra de amor eterno.
Y los tambores suenan bonito al ritmo bello de tus ojitos.

Ay, ay que lindo, que lindo estar enamorado
Ay, ay que lindo, que lindo estar enamorado


El que halla esposa, halla el bien;

y yo te hallé a Ti mujer
El que hay esposa, halla el bien;
y yo te hallé a Ti mujer

Pero que... Ay, ay que lindo, que lindo estar enamorado
Ay, ay que lindo, que lindo estar enamorado
Ay, ay que lindo, que lindo estar enamorado
Ay, ay que lindo, que lindo estar enamorado
