So how about this as an idea. We know from the resonance synchronisation video that when two ‘pendulums’ are kept nearby they tend to synchronise. So now lets keep multiple such pendulums in a line such that they all synchronise to each other. That way, we are sure that the two pendulums have the same time period. Now, using a clock, you measure the time taken for each swing of the pendulum. Now given that your pendulums are synced, you can know launch a beam of light and use the pendulum swing as your measure of time taken. So now, you convert that into time it took light to reach and you have an answer for one-way speed of light. Now, you repeat this in any direction you can think of, and you will have your answers. I know it is incredibly hand wavy, but since we need two objects for time-keeping to sync, I thought it should be pendulums, not clocks.
Funny how the end goal is to live "as if quantum computers were never invented in the first place." And yet the silly boffins keep striving to invent them, and more.
lol if you want to learn how to mime/act lifting a heavy sheet/tile/lid/etc this is perfect to copy from 10:39 Moving things through magnetic fields is weird hard work XD
There's a reason hardware stores sell wire of several different diameters. The *cross sectional area* (not surface area) of wires dictates how much DC or low-frequency AC current they can carry. This is a basic fact of electrical engineering that can be verified from any source including your local Home Depot associate. Sustained transmission line dynamics and the "skin effect" only apply to alternating currents of high enough frequency (usually RF in practice) for EM effects to predominate. This video fails to clarify this distinction and is extremely misleading.
A true sign of intelligence is being able to take a topic that is horribly complex and explain it in a way that other people can understand. The fact that you were able to take a topic that even I don't understand fully, and I've been in the computer science and math field for 20 years, and explain it in such an easy to understand way (without all the gory formulas behind the concepts) is just mind boggling to me. Even after watching this video, I still couldn't imagine sitting down myself and trying to map out a way to explain this topic to your average person. I have MAD respect for what you've done here.
Dear veritasium, ever since I saw your video on the collatz conjecture, the logistic map and gaussian distribution my interest in maths has increased. You presentations are so great and I appreciate them. Please make more videos about maths. You make everything so understandable. Thank you so much!!
Ah confirmation bias. I've thought I was a visual learner, but only once I discovered a memory techniques book which worked wonders for me. Since then i've used it through education.
This is so much b.s. you can't send anything out of earth orbit ,why do you keep lying ,oh yeah you're getting a lot of pocket change, keep the fools fooled I guess.
I find the idea of the point lattice really interesting, although I am not sure about one thing.... Since the "public keys" are those sets of "bad vectors" (which take a long time to use to find the correct path on the lattice to decode the data), don't they still contain valuable information about the lattice itself? I mean, couldn't a potential attacker find a way to generate a set of "good vectors" from the set of "bad vectors" so that they describe the same n-dimensional lattice, simplifying the decode operation?
One thing that should be considered, In 2020 a Quantum computer crashed attempting to factor the number 35. If this instability remains, then Quantum computers may not be as good as it's hype in breaking RSA.
This video gave me so many epiphanies about the topic at hand as well as other topics, such as how I approach education for others and for myself. The ability to create such digestible breakdowns of seemingly complex and new concepts is inspiring. There is a little bit of everything in here. The visualization and discussion is presented in such a way that I am presented with a sort of "call to action" my brain is engaged as if I have been asked to solve this problem but I am also being guided to the answer as well as the obstacles that are presented to me. Thank you for this!
I need help... I'm interested in physics and about space but I have a civil engineering degree.... I want to learn more about the world and what kind of classes or what do you suggest me to take up for my masters?
Hi Derek and the entire Veritasium team, first of all I want to thank you wholeheartedly for such a lucid explanation. I have one question though - 9:31, how are we certain that p and q must come from one factor each on LHS (g^r/2+1 and g^r/2-1)? Why is it that one of these factors can't have both p and q?
So how come it's the wire that gets hot, thats energy causing the heat, and the fuse that blows, in the transformer the magnetic Flux agitated the neighboring electrons.
DUDE THATS LITERALLY WHY I FAILED MY SCIENCE CLASS I NEVER UNDERSTOOD HOW LIKE. ENERGY TRAVELED IN METAL CYLINDERS LIKE STRAWS. im so annoyed. cause ive asked this multiple times before and like noone knew how to answer ? and i just couldnt get past it. it made absolute 0 sense in my head. goddddd 😅😭
