Episode description

Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series, also available on YouTube here: https://wolfr.am/youtube-sw-qa

Questions include: Can you explain rasterization? -  Does the human visual system use a molecular-scale version of rasterization? - When I close my eyes and apply pressure, why do I see colored dynamic geometric patterns? ​I also see the grid, and it's interesting how it fades when your normal vision fades back in, and the gray/black squares sometimes oscillate while maintaining the grid structure. - Do you have any stories about Fresnel lenses? I just got the Meta Quest 2 VR headset and it uses them; the same kind that a rear-projection TV or a lighthouse uses, which is amusing. - ​Considering visual perception discontinuous or discrete, can we consider it quantized? In that case, could it be calculated as "discrete packets of visual perception," based on quantum physics?
