#Veritasium #video about #ASML #EUV #photolithography machines, which apparently cost US$400 million each. Explains #optics a bit, including defining NA (as the sine of half the cone included angle) and the Rayleigh equation. Traces the #history through Kinoshita and Andrew Hawryluk, with an #interview with the latter, and extensive interviews with people at ASML. #precision
