MinutePhysicsシーズン 2016

In MinutePhysics Henry Reich provides concise, easy to understand explanations of physics principles in every day language in about a minute. And to make the physics easier to understand he hand sketches diagrams so you can also see what he's talking about. Topics tend to previews or introductions to more in depth programs available through various online services.

第1話
How To Discover Weird New Particles - Emergent Quantum QuasiparticlesThis video is about weird condensed matter systems, aka materials that have bizarre emergent particles in them that are unlike most other particles in the universe.

Why Are Airplane Engines So Big?The physics behind the perfect size of a jet engine.
Solution to the Grandfather Paradox
第9話
Solution to the Grandfather ParadoxWhat if you went back in time and killed your own grandfather? Would you still be born? Or would you have thus killed yourself?

Gravitational Waves Explained Using Stick Figures
第12話
Gravitational Waves Explained Using Stick FiguresThis video is about gravitational waves in the weak field limit as discovered by the LIGO collaboration, explained by parallels to electromagnetic radiation, sound waves, water waves, etc. I want to see Cat LIGO ASAP!
Hitting the Sun is HARD
第13話
Hitting the Sun is HARDThis video is about the orbital mechanics of why it’s so hard to crash into the sun – the energy it takes to get there is astoundingly high, compared with leaving the solar system.
How Long Is A Day On The Sun?
第14話
How Long Is A Day On The Sun?This video is about the definition of a day, and how it applies (or not) on the sun. Solar day, sidereal day, universal coordinated time (UTC) day, etc. Length of a day.
The Twins Paradox Primer (Rotating TIME!)
第15話
The Twins Paradox Primer (Rotating TIME!)This video is about the famous “Twin paradox” of special relativity, and how time can appear to be faster for two different observers at the same time.
Complete Solution To The Twins Paradox
第16話
Complete Solution To The Twins ParadoxOne of the most famous paradoxes of all of physics – who's older? Who's younger? and WHY?
Why Doesn't Time Flow Backwards?
第17話
Why Doesn't Time Flow Backwards?This video is about why entropy gives rise to the arrow of time, and also how the initial low-entropy condition of the universe is responsible for the fact that we experience time right now, and how ultimately it will lead to the high-entropy heat death of the universe.
Do Cause and Effect Really Exist?
第18話
Do Cause and Effect Really Exist?This video is about why there's no such thing as cause and effect at the level of fundamental particle physics, and how our everyday experience of cause and effect arises due to entropy, the large-scale arrow of time, and the leverage certain events have over others. This can explain not only the existence of causes and effects, but also memories, records and so on.
Where Does Complexity Come From?
第19話
Where Does Complexity Come From?This video is about the difference between complexity and entropy, and how we can see complex things like life, planets, galaxies, humans, intelligence, consciousness, etc arising in our universe when the overall tendency of the second law of thermodynamics is towards increasing entropy and disorder. It turns out that gravitational collapse & other complex structures (such as tendrils that form when coffee and milk mix) arise naturally as part of the path towards increasing entropy.
How Entropy Powers The Earth (Big Picture Ep. 4)
第20話
How Entropy Powers The Earth (Big Picture Ep. 4)This video is about how we don't just need energy to power our lives, we need *low entropy* energy!
What is the Purpose of Life?
第21話
What is the Purpose of Life?This video is about how life arose and what its main function or purpose in the universe seems to be.

No Cloning
第23話
No CloningWhy you can’t clone Schrödinger’s cat: this video presents the full proof of the “No Cloning” Theorem in Quantum Mechanics – without any fancy math! (stereotypical qubit has been replaced with Schrödinger’s cat). The full proof relies on the linearity of quantum (aka unitary) transformations, and the tensor product of multiple systems, to show that perfect cloning is impossible (though teleportation is allowed)
