September Video Poll

Re: yesterday’s Star Trek video The Shrike is a reference to Hyperion, a sci-fi book by Dan Simmons (highly recommend!), but I’m guessing it’s only related to the ship by appearance. I think you’d also enjoy the sci-fi fantasy book “A Psalm for the Wild-Built” by Becky Chambers :) Also I’d totally make a Spot 73 plushie and give it to you (if you wanted, of course)! I’m already in Cambridge MA and love to craft cute things, so it doesn’t seem that inconvenient? Idk

I want to learn about holograms! I regret having clicked in a QCD video 😭

My picks: (just for curiosity/engagement) - Concrete (obvious reasons); - Speed of light (I've watched a few videos about it, I'd love to hear Dr. Collier's "take"); - Free Will and Super Determinism (also would love to hear her take); - Scientists and engineers differences tackling assignments (we engineers love how Dr. Collier talk about us)

Looking forward to the concrete one, Angela. I haven’t kept up since I first heard the world is running out of sand, let alone the carbon issues. I never even thought that sand would be one of the main problems.

All of these sound like excellent topics!

I want to know everything about concrete. Roman Empire concrete, does lichen break down concrete over the centuries? Varieties of modern concrete, concrete curing process and the Hoover Dam still making heat from curing. What will be left of concrete and rebar for archeologists a thousand years from now? What share does concrete manufacture play in Carbon Dioxide releases and warming the Planet?

I had to vote for the free will one

Don't forget your catchphrase!

With respect to concrete, a friend of ours who owned a small concrete business said it takes a hundred years to fully set, so if you can confirm or rebut and maybe explain?

Alternative: What kind of math do you need to grasp cosmology?
