New video - ad free! - I used to hate QR codes. But they're actually genius
Added 2024-09-30 19:48:07 +0000 UTCQR codes are everywhere — Tickets, Restaurant menus, Boarding passes, Vaccine records, and in some countries, even money! They come in all shapes, some that don’t even look like QR codes at all. But how do they work, even when a third of the code is damaged? To find out, I built one from scratch.

I love the menu at 16:37. I can just see Ralph Fiennes screaming, “THERE ARE NO SUBSTITUTIONS AT THE VERITASIUM!” I will admit to having always had a hard time visualizing higher dimension hypercubes projected onto a plane, but then again, I almost never know where my reading glasses are, and that’s just a tuple in 3-space.
