Modeling Memory for Top Performance

Wired explores a different Wozniak:
Twenty years ago, Wozniak realized that computers could easily calculate the moment of forgetting if he could discover the right algorithm. SuperMemo is the result of his research. It predicts the future state of a person’s memory and schedules information reviews at the optimal time. The effect is striking. Users can seal huge quantities of vocabulary into their brains. But for Wozniak, 46, helping people learn a foreign language fast is just the tiniest part of his goal. As we plan the days, weeks, even years of our lives, he would have us rely not merely on our traditional sources of self-knowledge — introspection, intuition, and conscious thought — but also on something new: predictions about ourselves encoded in machines.
Given the chance to observe our behaviors, computers can run simulations, modeling different versions of our path through the world. By tuning these models for top performance, computers will give us rules to live by. They will be able to tell us when to wake, sleep, learn, and exercise; they will cue us to remember what we’ve read, help us track whom we’ve met, and remind us of our goals. Computers, in Wozniak’s scheme, will increase our intellectual capacity and enhance our rational self-control.
Bionic Eye a Reality

Finally, the bionic eye is a reality [timesonline]:
Surgeons have carried out the first operations in Britain using a pioneering “bionic eye” that could in future help to restore blind people’s sight…
The device — the first of its kind — incorporates a video camera and transmitter mounted on a pair of glasses. This is linked to an artificial retina, which transmits moving images along the optic nerve to the brain and enables the patient to discriminate rudimentary images of motion, light and dark.
