Thank you Jason for being a great teacher. For years I’ve been a subscriber on mathtutordvd and you’ve taught me everything starting with simple algebra all the way to calculus and electrical engineering. You explain abstract concepts easily and ten times faster than any professor I’ve ever had and I’m soon graduating engineering. Thank you from Sweden
Demonstrating the flamability probably would have been inappropriately dangerous. Besides, it doesn't seem like your style. You're unsurprisingly within the detailed scientific parameters you uphold. 😂 🔥 🧪 ⚗️
Pretty interesting topic for a chemistry class. Thanks a lot sir, you have picked my curiosity (can we have a series explaining the chemistry of other... critical areas of human body like armpits, feet, etc? not joking, I'm really curious now)
There is no more didactic way to teach something than to show the theoretical concepts and IMMEDIATELY do an experiment to show how they play out in real life. Jason, you never disappoint. What a great teacher.
Noone going to mention that the expansion starts at the core of the balloon ? The only way this explanation makes sense is if we only can look on a 2dimensional plane.
Can’t really tell what you’re trying to say but also we probably live on the “surface” of a universal geometry more complex than a balloon, it’s just really hard to conceptualize in a 30s video. The universe’s geometry is probably impossible to find out. We’ve tried many methods, all which came from our first conceptualizations of living on the surface of a 3d object, though if our understanding of science is correct we live on the surface of an object with more axies.
@@signalsgone8503 basically im saying that the concept of no origin or center of expansion is debunkes by the singularity or fixed point at time of big bang. There was indeed a singular point of expansion, we are unable to see it due to either spatial curvature or because we cannot see along the dimension that expansion came from.
off topic, but, uh, from the popcorn model of reality: make the universe manageable by applying simplicity. our universe can be divided into 2 parts. the beginning and the end (dissipation). now imagine a higher pitched harmonic of our reality: This is the realm of dark matter. the ratio in the relative energy difference between the adjacent harmonics has a magnitude of between 10e64 and 10e72 7 levels of force exists within these harmonics: time* gravity weak strong em human thought process* big (supreme)* *not recognized as a force our universe exists from the interaction of these forces em is the dominant force in our measured universe. the most massive dark matter particle is equal in mass to the least massive detected particle pair (neutrino/antineutrino). shall i go on in a different post or continue here or just shut up?
Please make it possible to send messages to past. my father kim kyudong died snu hospital at 2024.04.15. I must prevent that death. there must be way to send messages to past by using sun and earth's revolution, space-time, sun's gravity. reception of messages will be done by radio telescopes that monitor extraterrestrial radio waves 24 hours a day. please help me.
If universe is expanding and every object is moving away ot stretching apart from one another then why do galaxy collide or asteroid collide. They should have been moved apart instead
