The Absurdity of Detecting Gravitational Waves (09:07)

A head-vaporizing laser with a perfect wavelength detecting sub-proton space-time ripples.

When scientists want one megawatt of laser power, it's not just for fun (though I'm sure it's that too), it's because the fluctuations in the number of photons is proportional to their square root, making more powerful beams less noisy (as a fraction of their total). The smoothest mirrors were created not for aesthetic joy but because when you're trying to measure wiggles that are a fraction the width of a proton, a rough mirror surface simply won't do.

The most beautiful idea in physics - Noether's Theorem (09:53)

Looking Glass Universe · 2 years ago
Homework: -What do you think of this idea? Have you heard of it before? -Maybe you’ve heard about things like super symmetry in physics- try find out how that’s related. -If you know some calculus and classical physics, try and find a proof of this theorem. -Try come up with strange systems with strange symmetries- then see if you can figure out what’s conserved. The proof and maths of Noether's theorem: There are two ways to approach Noether's theorem that I know of. The most common is through Lagrangian mechanics- where the proof is surprisingly simple but unfortunately quite opaque (see http://math.ucr.edu/home/baez/noether...) . The other way, and the way I allude to in this video, is using hamiltonian mechanics. I find this way a bit easier to understand and it involves the generators of the transforms more. A great resource for this is the last lecture in this course: http://www.physics.usu.edu/torre/6010... but it requires multivariable calculus and a little knowledge of Hamiltonian mechanics.

Quantum Entanglement & Spooky Action at a Distance (09:16)

Veritasium · 3 years ago
Does quantum entanglement make faster-than-light communication possible? What is NOT random? http://bit.ly/NOTrandoVe First, I know this video is not easy to understand. Thank you for taking the time to attempt to understand it. I've been working on this for over six months over which time my understanding has improved. Quantum entanglement and spooky action at a distance are still debated by professors of quantum physics (I know because I discussed this topic with two of them). Does hidden information (called hidden variables by physicists) exist? If it does, the experiment violating Bell inequalities indicates that hidden variables must update faster than light - they would be considered 'non-local'. On the other hand if you don't consider the spins before you make the measurement then you could simply say hidden variables don't exist and whenever you measure spins in the same direction you always get opposite results, which makes sense since angular momentum must be conserved in the universe. Everyone agrees that quantum entanglement does not allow information to be transmitted faster that light. There is no action either detector operator could take to signal the other one - regardless of the choice of measurement direction, the measured spins are random with 50/50 probability of up/down.

Why Do Venomous Animals Live In Warm Climates? (11:40)

Veritasium · 5 years ago
Subscribe to Veritasium - it's free! http://bit.ly/YSWpWm As a Canadian-Australian, I have always wondered why it is that Australia has so many venomous animals that can kill you while Canada has virtually none. But it's not just Australia - it seems like all beautiful, warm places are cursed with venomous native species. So I set out to find the truth: why have all these venomous species evolved in the world's best holiday destinations? I asked chemists, visited the zoo, interviewed entomologists and snake experts. The answer I found was complicated: 1. The majority of venomous species are ectotherms, cold-blooded creatures whose internal temperatures are governed by their surroundings. 2. This means they have limited periods of activity - mainly while it's warm out, and can only exert short bursts of energy, so they are generally "sit and wait" predators. This may explain why they, more than mammals or birds, evolved venom. 3. It also explains why there are more of these species in warm climates. There are more of all species in warm climates, but this trend is especially pronounced for ectotherms. 4. So there are a greater number of venomous species in warm places, simply because there are more species in warm places. Cold climates still have venomous creatures, like the rattlesnakes of Canada and European vipers. 5. But history also has a role to play. In Australia, there were no snakes until 20 million years ago when a venomous sea snake from Asia encountered the land, sending venomous species to all corners of the continent. Later non-venomous arrivals have done well in the tropics but not as well in Australia's colder climates, so venomous types still dominate there. Hawaii has no venomous land snakes and nor does Jamaica. 6. The recent ice age also would have driven ectotherms from the northern parts of the Northern Hemisphere. This is why there are no snakes in Ireland, for example.
