Practical Telepathy: The Science & Engineering of Mind-Reading

32 views

Published on

From van Vogt's Slan to Willis's Crosstalk, telepathy has been a staple of science fiction. But what are the real world chances of reading another person's mind? With MRI & PET scans we can see what images a person is thinking of, with brain implants we can help the blind to see, and -- the way the science is going -- we are only a half-step away from direct mind-to-mind communication. Nothing to worry about here!

This is the Capclave 2018 version
