S2016 E13 • Hitting the Sun is HARD

This 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.

S2016 E14 • 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.

S2016 E15 • 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.

S2016 E17 • 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.

S2016 E18 • 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.

S2016 E19 • 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.

S2016 E23 • No Cloning

Why 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)
