Journal: San Francisco

Most people who come to visit San Francisco probably expect it to be more "high tech" than it really is, when in reality NIMBY-ism and the like have set back many a thing, notwithstanding cell phone towers and such.

Comment: Fond memories of Physics exercises in Loomis Lab (Score 1) 162 162

I have fond memories of taking Physics quizzes and exercises on the PLATO machines at Loomis Laboratory while an undergraduate engineering student at the University of Illinois at Urbana Champaign in the early 90s. The plasma monitors with their orange glow were cool for such "old" technology.

Inventor Demonstrates Infinitely Variable Transmission 609 609

ElectricSteve writes with this excerpt from Gizmag: "Ready for a bit of a mental mechanical challenge? Try your hand at understanding how the D-Drive works. Steve Durnin's ingenious new gearbox design is infinitely variable — that is, with your motor running at a constant speed, the D-Drive transmission can smoothly transition from top gear all the way through neutral and into reverse. It doesn't need a clutch, it doesn't use any friction drive components, and the power is always transmitted through strong, reliable gear teeth. In fact, it's a potential revolution in transmission technology."

Researchers Build Evolving Brain Computer? 114 114

destinyland writes "'We have mimicked how neurons behave in the brain,' announces an international research team from Japan and Michigan Tech. They've built an 'evolutionary circuit' in a molecular computer that evolves to solve complex problems, and the molecular computer also exhibits brain-like massive parallel processing. 'The neat part is, approximately 300 molecules talk with each other at a time during information processing,' says physicist Ranjit Pati of Michigan Tech. When viewed with a scanning tunneling microscope, the evolving patterns bear an uncanny resemblance to the human brain as seen by a Functional MRI. Using the electrically charged tip of a tunneling microscope, they've individually set molecules to a desired state, essentially writing data to the system. And while conventional computers are typically built using two-state (0, 1) transistors, the molecular layer is built using a hexagonal molecule, and can switch among four conducting states — 0, 1, 2 and 3, suggesting it may ultimately have more AI potential than quantum computing."

Aren't you glad you're not getting all the government you pay for now?
