Math Encounters -- The Cosmic Distance Ladder
HTML-код
- Опубликовано: 27 авг 2024
- How do we determine distances between the earth, sun, and moon, and from the sun to other planets, stars, and distant galaxies? We can't measure these directly, but indirect methods, combined with some basic high school math, can provide convincing and accurate results. Climb a "cosmic distance ladder" with UCLA Professor of Mathematics and 2006 Fields Medalist Terry Tao, as he shows us how measurements of nearby distances can be used to estimate distances that are out of this world. Terry will be introduced by Michael Sipser, Barton L. Weller Professor of Mathematics and Head of the Mathematics Department at Massachusetts Institute of Technology.
Math Encounters is a public presentation series celebrating the spectacular world of mathematics and presented by the Simons Foundation and the National Museum of Mathematics.

The audience looks really bored, but this is one of my favourite encounters so far.
themanu I'm only ten minutes in and it certainly seems interesting. The audience however... I feel a little sorry for them
I was chuckling looking at the audience members half asleep and/or yawning...some were downright involved in their own world. Lol who said astronomy isn't useful? It could put adults to sleep! Hahaha....
But I am also glad that there a handful few who liked & appreciated the topic & the man himself Terry Tao. Few prolly knew in that room that they were listening to a Fields medallist. I'd rather listen to his lec than Hawking's.
People have the most intelligent man on earth in the same room, and still figure out to sleep.
I demand execution.
No , the audiences were just close the eye with thinking. 😎
terry tao is awesome
Thank you for sharing this video. It sure helps me connecting the dots about the history of science. Terence Tao sure knows how to explain complex stuff to non scientists.
I can imagine it could be a long seat for the scientists, who already know lots of what he's explaining.
Windows XP ???
😅
7:46 blue dress XD
9:41 is better I think.
Agreed..
This bugs me a lot. The moon rotates at same rate it orbits earth. This means to any particular nation it presents a 'same' face, but surely other nations see other perspectives, ie at some point some place sees what to us would be the back side. There is no way for a rotating body not to... right ?
Hythloday71 Put your hands up opposite each other and make one clenched and the other flat. Keep the clenched fist still and move the flat hand around it, keeping it facing the clenched fist. You'll realize that your wrist is rotating in a direction that keeps the flat hand facing the clenched fist.
Cool. thanks for that.
"It's Time", temporal superposition phase-state is an "astronomical-lensing" cause-effect, because, in accordance with the relative frequency-eternal density of probability and intensity of Quantum Information, the information is condensed or divergent (in mathematically coordinated time-timing => space-spacing connection). So the balanced focus or tuning appears to be "flat" brane-space, like the surface of a pool.
Astonomy Cosmology is the same starting point for most curiosity about the environment of day-night light-shadows and strange things like what fish see above the water and we see below because of optical densities.
This process of frequency-focussed quantum information fills out the Universal wave-package phenomenon, and is how the sense of it, tuned to brain frequencies, becomes our mindful cultural perceptions.
Particularly when presented so expressively as in this lecture.
Another temporal way to observe the 1-2-3Discrete-Dimensional dominance frequency, (or shell-horizon for infinite-eternal wave-particle banded phenomena), is to imagine the dominant interpretation of identity shifting the 1-0D resonance vector of unitarity by primes to the 1st law of Thermodynamics jump that is the wave-reciprocal of the electron orbital emission decay of EM radiation relative rate of the "conduction-chord" Quantum Fields Mechanism in Temporal Superposition. All that moves is the focal tuning, similar to tuning radio transmissions, or tensioning one of the jam-tin and string phones, because the tension aligns the higher atomic frequencies in the string that are modulated to conduct sound, things we made as toys that "everyone knows", string connection, circumstantial event-theory(?).
(The holistic principle needs to be thought through, for beginners and everyone else)
The study of Cephied Variables and oscillation rates is related to photon emission by the same principle.
TESSARACT VISUALIZED NOW.
MATH MUSUEM.
Introducing the introducer. Bit smug
TET.
Probably a clever guy but not a very compelling lecturer; his voice is up and down in volume tailing away at the end of sentences to become rather indistinct.
Yes , absolutely agree. Though even now is way better then.
The lecturer believes in the linear progress of human knowledge, despite overwhelming evidence that ancient man knew the dimensions of the earth and moon and sun - and that we lived on an oblate spheroid. He thinks ancient Greeks began delivering us from ignorance, but the Greeks learned their science from Egypt and Babylon, etc.
