In the third act of "Swan Lake", the Black Swan pulls off a seemingly endless series of turns, bobbing up and down on one pointed foot and spinning around and around and around ... thirty-two times. How is this move — which is called a fouetté — even possible? Arleen Sugano unravels the physics of this famous ballet move.

Lesson by Arlene Sugano, animation by Dancing Line Productions.

In this video, we look at refraction of waves. First we explore what is meant by refraction and look at how this is due to changes in the speed of waves as they change from one medium to another. Finally, we use the idea of wavefronts to explain how changes in wave speed cause refraction.

This is the Map of Quantum Physics and quantum mechanics covering everything you need to know about this field in one image. Check out this video's sponsor https://brilliant.org/dos
And grab this poster here: https://store.dftba.com/collec....tions/domain-of-scie

I’ve been fascinated with quantum physics and quantum mechanics for a very long time and I wanted to share the subject with you so I made this map of quantum physics to lay out the ideas within the subject, to set some bounds on it so you know its not endless and to introduce you to lots of concepts that if you are interested in them you can dig deeper. When you are approaching a subject like this that’s so complicated it can be quite challenging because you don’t know where to start and you don’t know how all the concepts relate to each other so hopefully this will put everything in context.

This playlist expands on this video with lots of other more specific videos that dive deeper: https://www.youtube.com/playli....st?list=PLOYRlicwLG3

Director Christopher Nolan and author Kip Thorne speak to TIME's Jeffrey Kluger about the physics of 2014 blockbuster Interstellar. There's no arguing about the blockbuster status of Interstellar, director Chris Nolan's latest box office phenomenon. But plenty of people are debating the science component of that sci-fi tale'”which is how it always is when a movie based in something as non-negotiable as physics has to take just enough liberties to make the fiction part of the story fly. Nolan was determined to keep his narrative scientifically honest, which is why he signed on as technical adviser celebrated Caltech physicist Kip Thorne'”who literally wrote the book on (much of) the movie's cosmology. TIME's Jeffrey Kluger sat down with Nolan and Thorne to talk about human curiosity, the art of sci-fi filmmaking and the one time the two of them locked horns over a plot point.

When you hear the word "work," what is the first thing you think of? Maybe sitting at a desk? Maybe plowing a field? Maybe working out? Work is a word that has a little bit of a different meaning in physics and today, Shini is going to walk us through it. Also, energy and power!

#gravity #science #song
A song I wrote to introduce my elementary students to the concept of gravity and to 'maybe' explain why I'm always falling down! (lyrics below)
From Newton's basic laws of motion.
LYRICS
Gravity is all around,
When I fall it pulls me to the ground!
A force that you and I can’t see,
Pulls me toward you, and you towards me!
Keeps us from flying into space,
Why I fall when I trip on my shoelace,
That cool force is gravity,
Thank Isaac Newton’s apple tree!

Gravity,
A force that’s pulling you and me,
Gravity,
Pulls Jupiter, Mars, and Mercury,
Gravity,
A force that’s pulling you and me,
Down and down,
As our Earth spins round and round…

I fall,
You fall,
We all fall down!
The force of gravity
Pulling us to the ground,
You can never see it,
It never makes a sound,
It makes our mother Earth,
Go round, and round and round,
The planets have their orbits,
Because of gravity,
Pulls on flying objects,
Pulls on you and me!
Makes an apple fall,
Lets us slip down slides,
Makes a yo-yo go,
And oceans have their tides!
Gravity, we all fall down!
Gravity, we all fall down!
Gravity, we all fall down!
Gravity, we all fall down!

Hey gravity, hey gravity hey,
Don’t make me fall down today!
Here’s the reason, why I’m scared,
32 feet per second squared!
Hey gravity, hey gravity hey,
Don’t make me fall down today!
Here’s the reason, why I’m scared,
32 feet per second squared!

Gravity,
A force that’s pulling you and me,
Gravity,
Pulls Jupiter, Mars, and Mercury,
Gravity,
A force that’s pulling you and me,
Down and down,
As our Earth spins round and round…

Pulls Jupiter, Mars, and mercury,
And all the planets I can see,
Pulled in orbits around the sun,
The sun is pulling everyone?
Sun has so much gravity,
A whole bunch more than you and me!
Great big mass, big gravity,
I’d weigh much more on the sun you see…

I’d weigh much more,
On the sun you see,
Great big ball of mass,
Means more gravity,
The great amount of mass,
Means the greater the pull,
A dog has less mass,
Than a cow or a bull!
It’s not too strong,
But it’s all around,
If it was real strong,
We couldn’t jump up off the ground,
Gravity’s good,
Based on mass not girth,
Gravity’s good,
It holds us to the Earth!

Gravity, we all fall down!
Gravity, we all fall down!
Gravity, we all fall down!
Gravity, we all fall down!

I'm sure you've heard of Isaac Newton and maybe of some of his laws. Like, that thing about "equal and opposite reactions" and such. But what do his laws mean? And how do they help us understand the world around us? In this episode of Crash Course Physics, Shini talks to us about just that.

Errata and clarifications.

I endeavour to be as accurate as possible in my videos, but I am human and definitely don’t know everything, so there are sometimes mistakes. Also, due to the nature of my videos, there are bound to be oversimplifications. Some of these are intentional because I don’t have time to go into full detail, but sometimes they are unintentional and here is where I clear them up.

1. “Isaac Newton invented calculus.” Actually there is controversy over who invented calculus first Isaac Newton or Gottfried Leibniz. Regardless of who it was I have used Leibniz’s mathematical notation here and so he definitely deserves credit. I did’t know about all this so thanks to those who pointed it out. https://en.wikipedia.org/wiki/....Leibniz%E2%80%93Newt
2. “Maxwell derived the laws of electromagnetism.” This is a simplification as Maxwell’s work was built on the backs of other scientists like Hans Christian Ørsted, André-Marie Ampère and Michael Faraday who discovered induction and saw that electricity and magnetism were part of the same thing. But it was Maxwell who worked out all the maths and brought electricity and magnetism together into a unified theory. https://en.wikipedia.org/wiki/....Electromagnetism#His
3. “Entropy is a measure of order and disorder”. This is also a simplification and this does a good job of explaining it better https://en.wikipedia.org/wiki/Entropy
4. Einstein and Quantum physics: I made it sound like quantum physics was built by people other than Einstein, but this couldn’t be further from the truth. Einstein got a Nobel prize for his work on the photoelectric effect which was a key result to show the particle-like nature of light. Funnily enough he never got a nobel prize for his work on Relativity!

Also, if you enjoyed this video, you will probably like my science books, available in all good books shops around the work and is printed in 16 languages. Links are below or just search for Professor Astro Cat. They are fun children's books aimed at the age range 7-12. But they are also a hit with adults who want good explanations of science.

00:12 Mould effect
It's obvious that the weight of the heavy falling beads is pulling the remaining beads from the pot. However, it's not so obvious what's causing the large arc and why the beads don't just slide directly over the edge of the pot. It's said that you should view the chain as a series of short ridged rods rather than a flexible string of isolated beads.
When the beads are pulled out of the pot by the weight of the falling beads it causes the ridged rods not only to be lifted but also to rotate. The combination of these two forces causes the end that is not being picked up to push down on the pot which in turn creates a kick. It's this kick that sort of pushes the beads up out of the jar while they are also being pulled down from the other-side and thus the arc is formed. Check out the full explanation here if you're still not satisfied. https://goo.gl/QaRyZZ

00:47 Cool pressure trick
Heating air causes it to expand and cooling it causes it to contract. The boiling water in the bottle causes the glass to get very hot so the air inside the glass also gets hot causing it to expand. When the bottle is put into the cold water it quickly cools causing the air inside to contract rapidly which creates a vacuum and sucks the water up.

01:54 The lenz effect
"Lenz's law states that the current induced in a circuit due to a change or a motion in a magnetic field is so directed as to oppose the change in flux and to exert a mechanical force opposing the motion." When the magnet is dropped into the conductive alloy pipe it causes a change in magnetic flux. This change in magnetic flux creates a current in the Aluminium pipe which opposes the change and slows the magnet down in order to reduce the change in flux.
This video explains things way more thoroughly. https://goo.gl/idAvZs

02:56 Anti-gravity water trick
There are a couple of forces at work here, air pressure and surface tension. The atmospheric pressure all around us helps to hold the plastic in place. In addition to this, there is a small pocket of air at the top of the bottle. Because no more air can get to this pocket an area of low pressure is formed. A combination of low air pressure inside the glass and higher air pressure outside of it help to keep the plastic in place.
Next is surface tension and adhesion. Water molecules are attracted to each-other like little tiny magnets with a positive and negative end. On the surface of the water, the molecules are able to get closer to each other than below the surface, this creates a sort of elastic surface layer.
Adhesion occurs because of the water molecules positive and negative ends are not only attracted to each other, but also to other materials such as the plastic circle in this experiment. This causes the water molecules to adhere to the plastic whilst maintaining the surface tension with the other water molecules. It is a combination of all these factors that keep the plastic in place and stop the water gushing out. Check out this post for a more detailed explanation. https://goo.gl/crM6Xy

04:16 Water on a string surface tension trick
^^^This trick works on the same surface tension and adhesion principles as the one above ^^^

04:52 Ring catch chain trick
The trick with this one is in how you drop the ring. If you let go of the ring with both fingers at the same time it would just drop to the floor. What you need to do is just release your thumb and keep your finger still. When you do this it causes the ring to fall at an angle which in turn causes the chain to loop itself over the ring and get caught.

05:43 Fork and spoon center of gravity trick
Every object has a center of gravity. This is the central point at which gravity acts upon the object. When you position a fork, spoon and toothpick in this way, the center of gravity or the pivot point happens to be completely central and towards the far end of the toothpick which just looks so wrong. It looks even more impressive when you burn the toothpick at both ends, this has no effect on the centre of gravity so everything remains balanced. The reason the toothpick does not continue to burn past the metal of the fork or the glass is that when it reaches these points it's robbed of its heat and goes out.

Thanks to supermagnete.com for providing me with free magnets. Here are the details of the 3 experiments.

Nails in repulsion.
The nails are magnetized by the super magnet all with the same polarity, therefore between them there is magnetic repulsion and they are equidistant from each other going to reposition themselves after inserting a new nail. I used this magnet which is huge and very powerful, but you can do the experiment by scaling it and using smaller magnet and nails.

Spinning top with tractor beam
A game of attraction and repulsion forces make the top stand at a fixed distance from the magnetic tower as if it were a tractor beam.

In this weather science experiment, we walk through how to make a fire tornado. Using isopropyl alcohol, a wire trashcan, a ceramic bowl, and a Lazy Susan, we see how air movement affects fire! To use this weather experiment for a science fair project, consider questions like: How fast does the air need to be moving to create a fire tornado? What is the impact of the wire trashcan on a fire tornado?

❗️ SAFETY NOTE: Due to the nature of this experiment, it is best performed in a lab with a scientist or science educator.

▶️ Get supplies to make your own fire tornado:
http://www.beardedscienceguy.c....om/how-to-make-a-fir

▶️ Procedures
1. Place a sponge, cotton balls, or other absorptive material into a heat-resistant container, such as a ceramic baking dish.

2. Pour isopropyl alcohol into the heat-resistant container, enough to soak the absorptive material.
​
3. Place a wire trashcan into the middle of a Lazy Susan.
​
4. Place the container of isopropyl alcohol into the trashcan.
​
5. Using matches or a lighter, ignite the isopropyl alcohol inside the container.
​
6. Gently spin the Lazy Susan.
​
Note: To smother the fire and extinguish the flames, place a heat-resistant lid overtop the container until the fire is put out.

This is an interesting experiment to show the total internal reflection. We get the total reflection if the light enters to an optical less dense material and the incidence angle is big enough. The incidence angle at which the ray refracts exactly along the boundary line, is called the boundary angle of the total reflection. With the total reflection we can lead the light along the curved ways, as optic fibres or water jets. This is physics experiment for science project.

Zanimiv poskus za prikaz popolnega odboja. Do popolnega odboja pride, če svetloba vstopa v optično redkejšo snov in če je vpadni kot dovolj velik. Vpadni kot, pri katerem se žarek lomi ravno vzdolž meje, se imenuje mejni kot popolnega odboja. S popolnim odbojem lahko svetlobo vodimo po zakrivljenih poteh, npr. po optičnih vlaknih ali vodnem curku.

Simple density science experiment that you can try at home to see how liquids and objects with different densities behave. Using three fluids (syrup, water and oil) we can see they clearly have different densities, and form clear layers. By dropping items with different densities into the glass, we can see which fluids are denser than them.
