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.
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!
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.

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!
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!
