• Honestly and hilariously, it’s a brilliant idea for his specific experiment. Met the exact specs of what he was looking for.

• If you would like to work on a semiconductor fab tool that uses arrays of 100s of these MEMS-based AFMs for solving metrology and inspection challenges to boost yield, please reach out to me at [firstname]@icspicorp.com!

• In my first internship, with a hard disk drive company, I learned how to use an Atomic Force Microscope to measure the roughness of the hard drive platter (the disk). The texture variation is in the order of angstroms or nanometers. It’s incredible how the AFM works like the needle of a record player, not via optics, and sensing at the atomic level.

• What's the size difference between the AFM needle and the area of stored magnetic flux on a hard drive platter? If you used an AFM as a sort of record player, scanning along lines of little pits, what sort of theoretical information density could be achieved over the whole surface of the disk?

• I'm always happy to see one of my videos on HN! I'm really glad to be getting back into the habit of making new videos. Let me know if you have any questions or suggestions. See you at Open Sauce!

• Thank you so much for all the work you do for us.

• Your videos are extremely cool. Please keep going!

• I was a K6-12 science teacher since back before youtubes existed and it's so great to see educators whom genuinely enjoy sharing their passions with others.

  Keep it up! I know from experience (nowhere even near yours [†]) that these videos are grueling labors of love.

  [†] Couple of million-view+ viral OC hits, decades ago (god! we get wise too late and old too soon)

  My favorite part of this specific video of yours is that you give a "spoiler alert" early on, referencing a prior video (which I really enjoyed, too) [SPOILER ALERT]: the holograms you previously made are in fact flat =|

  Very cool. Thanks for using this incredible medium to continue sharing your passions!
