If a man born blind can feel the differences between shapes such as spheres and cubes, could he, if his sight was restored, distinguish those objects by sight (without touching them)? Posted on 2022/03/11 by Carl Robitaille Reply Q: "If a man born blind can feel the differences between shapes such as spheres and cubes, could he, if his sight was restored, distinguish those objects by sight (without touching them)?"This is Molyneux's Problem: a thought experiment from 1688.

Biological error correction codes generate fault-tolerant neural networks Posted on 2022/03/11 by Carl Robitaille Reply Biological error correction codes generate fault-tolerant neural networks I'm excited about our new paper: How can your thinking be so reliable when your brain is made of noisy, unreliable neurons? #GridCodes, 1st discovered in mice, allow perfect error correction! We can use this trick to build better #neuromorphic #AI chips.https://t.co/EPL3hGfIk4— Max Tegmark (@tegmark) March 1, 2022
