AMS Einstein Public Lecture in Mathematics: Terence Tao is UCLA's Collins Professor of Mathematics, and the first UCLA professor to win the prestigious Fields Medal. Less than a month after winning the Fields Medal, Tao was named a MacArthur Fellow. The following month, Tao was named one of "The Brilliant 10" scientists by Popular Science magazine, which called him "Math's Great Uniter" and said that "to Tao, the traditional boundaries between different mathematical fields don't seem to exist." Tao's AMS Einstein Public Lecture in Mathematics is titled "The Cosmic Distance Ladder."
The American Mathematical Society (AMS) sponsors a series of public lectures in mathematics entitled The AMS Einstein Public Lecture in Mathematics. The lectures began in 2005, to celebrate the one hundredth anniversary of Einstein's annus mirabilis. They are given annually at one of the Society's eight sectional meetings. The year 1905 marked the publication by Albert Einstein in Germany of three fundamental papers that changed the course of twentieth-century physics. Einstein later moved to the United States, where he became a founding member of the School of Mathematics at the Institute for Advanced Study in Princeton.
Sponsored by the American Mathematical Society
Hosted by the UCLA Department of Mathematics, The Philip C. Curtis Jr. Center for Mathematics and Teaching and the UCLA Division of Physical Sciences. Additional support provided by the UCLA Chancellor's Office.

This talk is a classic how to give a speech lesson: Know your audience well, and choose your topic carefully. This content is all new to me, because I am not into astrophysics or astronomy. For an audience of mathematician, choosing a mathemtically related story and content will have bored the audience to DEATH as it may have been heard so many times.

Guy is super productive as a mathematician. Go check out his blog and all of the paper's he spits out. He has won a fields medal back in 2006 and in 2012 he proved that every odd number greater than 1 is the sum of at most five primes,without invoking the Riemann Hypothesis. This helps improve the status on proving Weak Goldbach's. The purpose of this lecture was obviously for the general public and more as a science history talk.

You are most welcome, oker59! I only listened to Tao and tried to figure out the 'simple math' he is referring to. I read how gnomon is used and based on that I made my assumption how exactly Eratosthenes used the gnomon to calculate Radius of the Earth. Circumference of the Earth as you mention can easily be calculated using 2 X Pi X R.

no problem, I found it. He measured the shadow length a few times around 12:00 o'clock and took the average. Then he made a triangle with right angle between gnomon stick and shadow(measured avg. length). Then he used this to find the angle X between the hypotenuse and the gnomon stick. Then he found 7 degrees is the difference between 90(angle at Syene ) and X (angle he just measured at Alexandria). Then he used cosine theorem for triangle with 2sides R(&7deg.), distance(Alexandria->Syene=5000)

Fascinating Adriana, I had only guessed from memory of reading Thomas Heath's "A History of Greek Mathematics." What else comes to my memory but I didn't bother remarking because the memory feels to faint is that it was Appollonius who did the gnomon generalisation of the sundial. Is this who? It's fascinating the gnomon calibrations of the sundial that you find; Erastothenes figured out the circumference fo the Earth from the shadows indicated at the same time in both Alexandria and Syene!

@oker59 11 жыл бұрын
I remember doing the simple math of Erastothenes calculation of the circumference of the Earth; you don't even need Pi! Still, you're showing pretty good mathematical ability. I must say your saying to measure the shadow length and find the average doesn't sound like something Erastothenes or anybody back then would do! Not to mention the use of trigonometry; well, maybe later after Erastothenes. Anyways, I looked up Heath's "A History of Greek Mathematics" and couldn't find who did . . .

Even if the Moon was flat, there would still be differences in the brightness of the Moon. This is because when close to perpendicular to the Sun, it is hit by less light which it could reflect, even if we assume very strong diffraction.

I have a question: I learned that DISTANCE itself is now calibrated by the speed of light. For example, let's say we know that the speed of light is 186,000 miles per second. And we know that a laser takes 2 seconds to bounce back from the moon. Therefore, the moon is 186,000 miles away (one second to get to the moon, and one second to return = 2 seconds). * rounded off for simplicity. However, if we were to measure the distance using trigonometry, and calculated the distance as 185,000 miles, then we would have to redefine our definition of a mile in order to make that number match 186,000 miles. How would such a variance affect our estimated measurements to distant galaxies?
@trogdorstrngbd
@trogdorstrngbd 6 жыл бұрын
The definitions for units are nowadays never changed that drastically because we have ways to measure these quantities very accurately. Your hypothetical situation also wouldn't have any effect on the definition of a mile because we don't define it based on the distance to the moon, but by the distance traveled by light in a fixed amount of time, which is itself defined by the emission frequency of cesium-133. Regardless, any definition-based effects on lengths as large and imprecise as those in astrophysics would be negligible.

Eratosthenes actually paid scholars btw to accurately measure there paces, he paid several to collect the average counted paces, they had to been the same height and where accounted in to the earths radius, merchants weren't reliable at that time as they won't count there paces when trading. So inaccurate, but I'm glad he said something similar to the idea of how he measured the distance.

The moon distance equation at 22:26 gives (D = 71.3 r) not (D = 60 r) 2r / 3hr = 2pi*D / 1 month 1 lunar month = 28 days, in hours 28*24 = 672 hr so: 2r / 3hr = 2pi*D / (672hr) => D = 2r * (672/3) * (1/2pi) => D = 71.3 r

. . . or who generalised the sundial. I reread the section on Erastothenes, and it makes no mention of sundials(as I thought; for some reason, my memory kept saying Appollonius). I looked up the index sundials and gnomons and I can't find anything. I'm sorry, but right now, i've dived back into comparative mythology; this time "The Golden Bough"; i tried for years to avoid reading this book; i hope to be done with it quickly enough and back to reading/thinking about mathematics.

OK, since the mistake appears twice, let me write one or two lines. Physicists count every object that would now be up to 93/2 gly away and can be seen through a telescope as part of the observable universe. This is because it would now be at most this distance away and is now observable, even though its light was emitted when it was much closer to the matter of which we are comprised.

If aristarchus concluded the the earth orbited the sun after computing its size and distance, how did he know to look for a difference between the half moon phase and the midpoint the quarter turn in it's orbit from the new moon? The diagram Tao shows for that calculation (where he shows the distinction between half way between the full and new moon and the actual observed half moon) already has the earth on a curved orbit around the sun. Put another way, wouldn't aristarchus have had to presuppose a heliocentric model to look for the difference between half the moons orbit and the point at which the earth and moons orbit meet at a right angle?

With his data, also distance to the Sun is 11 times Sun Radius - completely wrong result compared to Tao's presentation slides(20 times). Did anybody try to reproduce Tao's results and are you duplicating his results successfully?
