The Surprising History of Stellar Parallax

[tonylyons]

Copernicus, Book 4, Chapter 16. "How the Parallaxes of the Moon Are Determined" (1522?) discusses Ptolemy's observation of Parallax at Alexandria 150 AD +/-. The concept of PARALLAX has been considered for two (2) millennia.

Professor MathTheBeautiful, thank you for a short and sweet video/lecture on the Surprising History of Stellar Parallax in Partial Differential Equations. The History of Stellar Parallax is tied to different eras in Classical and Advanced Mathematics.

Hello,

You use the term believe. Belief is a leap of faith and is the furthest thing from scientific..

3 quick questions.

#1- How is it possible Polaris is said to shift 3/4 of a degree from Earth's daily rotation (since it is slightly off center in alignement) and yet there is no seasonal shift observed in Polaris from Earth's much much larger elliptical orbit path around an off center Sun of over 600 Million Miles?

#2- Over the course of our orbit around the Sun, which star has been followed for 1 year to show the 360 degree time lapse (or near time lapse) of its circular parallax journey? Have any stars been followed for a year?

#3- Since we are moving with the Sun and never return back to the same position, have we ever noticed diminishing or increasing parallax of all stars as we continually change our position in space?

We are in a local minimum?! Interesting.

Isnt movement all relative though? The earth revolves around the sun AND the sun revolves around the earth.

Where are the time lapse videos of stellar parallax? 1838? What a joke.
