    Terence Tao (tao@mathstodon.xyz)'s status on Sunday, 09-Feb-2025 05:20:03 JSTTerence TaoTerence Tao

    Many years ago, I met with Grant Sanderson (best known for his Youtube channel 3Blue1Brown) to discuss a possible topic suitable for his channel. I proposed the #CosmicDistanceLadder, and presented a version of my public #astronomy lecture on this subject for him, but for various technical reasons (and the fact that I was basically just reciting my slides), the footage was not suitable for a presentation. But a few months ago, we met up again, and this time we did manage to record enough content that he could apply his signature editing, graphics illustration, and narration to bring the story of the cosmic distance ladder to life, well beyond what I was able to do with my much cruder graphical skills. Part one of the final video can now be found at https://www.youtube.com/watch?v=YdOXS_9_P4U , and a "deleted scene" is available at https://x.com/3blue1brown/status/1888222450841722954 .

    I am also working on a book project on the same topic with Tanya Klowden, who also helped Grant with the historical background for the ladder; Grant mentions some of his discussisions with Tanya in a "secret vlog" https://www.youtube.com/watch?v=uq83hprtpGE . (See also our instagram https://www.instagram.com/cosmic_distance_ladder/ for this project.)
