Yes, but, e.g., CD/DVDs are also terrific because of how the lasers are used to read/write the disks. So, CD/DVDs are amazing even without the connection with computing. So, the computing is not the whole story. IMHO, similarly for the other examples I gave.

The size of the meshes needed for good-enough solutions to the PDEs is immense (and there's a reason the oil and gas industry has been buying supercomputers since the early days).
- graycat 10y agoI hadn't heard that PDEs were crucial to the practical progress in fracking. The applied math I heard about was really mostly just the fast Fourier transform (FFT) for deconvolution of seismic signals to identify rock layers. The FFT was in, what, 1968 or so so 40+ years ago? Well, the computers of 1968 could do some really good FFT calculations.
