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.

Have you ever found yourself pondering the mysteries of the atom? In this documentary, we're diving into some of the most thought-provoking questions that bridge the gap between the microscopic world of atoms and the expanse of the universe.
*Energy Source for Electron Movement:*
One of the wonders of atomic structure is how electrons orbit the nucleus. But where do these tiny particles get the energy to perform this intricate dance? We'll delve into the fascinating mechanisms that fuel electron motion.
*The Birth of the First Atom:*
Ever wondered how the very first atoms formed? Join us as we explore the cosmic timeline and the events that gave rise to the building blocks of matter after the Big Bang.
*Touching Atoms: Myth or Reality?*
Do atoms ever truly touch each other? Discover the surprising truth behind atomic interactions and the forces that come into play when particles get close.
*Identity of Identical Atoms:*
Are two atoms of the same element truly identical? We'll delve into the atomic world to uncover the subtle differences that can exist even within the same element.
*Colorful Atoms?*
Can atoms have colors? While atoms themselves aren't colorful in the visible spectrum, they can exhibit fascinating light-related behaviors that we'll explore.
*Overcoming Proton Repulsion:*
The positively charged protons in an atomic nucleus should repel each other due to their like charges. Explore the powerful force that prevents them from flying apart.
*Proton's Size Unveiled:*
How big is a proton? We'll zoom in to the subatomic level and discuss the dimensions of these fundamental particles that play a crucial role in atomic nuclei.
*Solidity in Empty Space:*
If atoms are mostly empty space, how can objects appear and feel solid? Join us to unravel the mysteries of solidity in the midst of atomic emptiness.
*The Dance of Atoms - Formation of Molecules:*
Why do atoms come together to form molecules? Discover the intricate chemistry behind the bonds that unite atoms into the diverse molecules we encounter.
*Neutron Stars - Giants of Nuclear Matter:*
Is a neutron star akin to a colossal atom? We'll explore the extreme conditions of these celestial wonders and their relationship to atomic structures.
*A Universe Within an Atom:*
Imagine the universe as an atom. Could there be a connection between the macroscopic and the microscopic? We'll embark on a speculative journey into this intriguing concept.
*Atoms After Life:*
Ever wondered what happens to your atoms after you pass away? We'll discuss the fate of the atoms that once composed your body and their journey through the natural cycle.
*Eternal Existence of Atoms:*
Do atoms last forever? Uncover the changes atoms undergo through various processes and consider the intriguing concept of their enduring nature.

What Exactly Is Curling?
http://mentalfloss.com/article..../23982/what-exactly-
"Olympic curling has taken to the ice, but if you're like most Americans, this writer included, the game is a bit baffling. Here's a quick, stripped-down primer on everyone's favorite icy alternative to shuffleboard."
Curling
http://en.wikipedia.org/wiki/Curling
"Curling is a sport which players slide stones across a sheet of ice towards a target area which is segmented into four concentric rings."

Quantum gravity is the hardest problem in physics. It's the attempt to unify the two pillars of modern physics: quantum mechanics and general relativity. It's the study of how gravity works at the quantum level, where the laws of physics are very different from what we experience in everyday life. One of the biggest challenges in quantum gravity is that gravity is the weakest force in nature. It's so weak that it's impossible to study for particles in the lab. We can only see its effects on very large objects, like planets and stars. Scientists have been working on quantum gravity for decades, but they haven't been able to come up with a complete theory. So it remains one of the biggest unsolved mysteries in physics, one that scientists are determined to solve.

This video is about the basic concept of electromagnetic induction.
electromagnetic induction is the basic principle of various type of motors and generators.
thank you so much for watching.
When you fall thousands of feet from the sky, it seems like something strange is happening with the laws of physics. Turns out, everything relies on a simple force - DRAG!

In this lesson, you will learn an introduction to physics and the important concepts and terms associated with physics 1 at the high school, college, or university level.
We will review Newton's laws of motion, projectile motion, force, energy (potential and kinetic energy), gravitation, momentum, collisions and more..
A simple and clear explanation of all the important features of quantum physics that you need to know. Check out this video's sponsor https://brilliant.org/dos
I have spent a lot of time thinking about how best to explain quantum physics and this is the result of all my hours of pondering, and I’m really happy with how it turned out. I decided to just explain it as it actually is, rather than rely on analogies. The video explains the quantum wavefunction, particle-wave duality, the measurement problem, the double-slit experiment, superposition, entanglement, quantum tunnelling, the Heisenberg uncertainty principle, and energy quantisation. Let me know if it was helpful! Cheers Dx

For a more detailed introduction to quantum physics: 'The Quantum Universe' by Brian Cox and Jeff Forshaw is good.
And a slightly more advanced but fantastic description of what we do and don't know about quantum physics is the excellent book 'Beyond Weird' by Philip Ball.
