UCLA Mathematician Works To Make Virtual Surgery A Reality

“A surgeon accidently kills a patient, undoes the error and starts over again. Can mathematics make such science fiction a reality? The day is rapidly approaching when your surgeon can practice on your “digital double” – a virtual you – before performing an actual surgery, according to UCLA mathematician Joseph Teran, who is helping to make virtual surgery a viable technology. The advantages will save lives, he believes.

“You can fail spectacularly with no consequences when you use a simulator and then learn from your mistakes,” said Teran, 30, who joined UCLA’s mathematics department in July. “If you make errors, you can undo them – just as if you’re typing in a Word document and you make a mistake, you undo it. Starting over is a big benefit of the simulation. “Surgical simulation is coming, there is no question about it,” he said. It’s a cheaper alternative to cadavers and a safer alternative to patients.”

Zombie Infection Simulation v2.3

Great idea:

Zombies are green, move very slowly and change direction randomly and frequently unless they can see something moving in front of them, in which case they start walking towards it. After a while they get bored and wander randomly again.

If a zombie finds a human directly in front of it, it tries to kill them. They will succeed, unless the human population is low. In that case, there is a chance the human will expect the zombie, and have a chance to attack first!

How to Live in a Simulation

Recently, Post-Atomic linked to this article about Nick Bostrom’s theory that we may be living in a simulation. Then Boing Boing posted a link to Bostrom’s paper. It makes me realize that Robin Hanson’s essay How to Live in a Simulation might be useful.

Abuddhas Memes is an excellent blog dealing with consciousness, entheogens, memetics, science, philosophy and “big brother.” It has featured such excellent links as How to Live in a Simulation, The LIDA Machine (a Russian device that uses mind altering radiowaves to paralyze people), and The Orion’s Arm World Building Group.
