NASA Probe Validates Einstein Within 1% 188

An anonymous reader writes "Gravity Probe B uses four ultra-precise gyroscopes to measure two effects of Einstein's general relativity theory — the geodetic effect and frame dragging. According to the mission's principal investigator, the data from Gravity Probe B's gyroscopes confirm the Einstein theory's value for the geodetic effect to better than 1%. In a common analogy, the geodetic effect is similar to the shape of the dip created when the ball is placed on to a rubber sheet. If the ball is then rotated, it will start to drag the rubber sheet around with it. In a similar way, the Earth drags local space and time around with it — ever so slightly — as it rotates. Over time, these effects cause the angle of spin of the satellite's gyroscopes to shift by tiny amounts." The investigators will be doing further data analysis over the coming months and expect to release final results late this year.

Feed Intel shows off "metro notebook" concept (engadget.com)

Filed under: Laptops

It looks like Intel has more than just wearable computers and newfangled UMPCs in mind for our future, with the company also recently showing off this slightly less far fetched "metro notebook," apparently aimed primarily at women. One of the most most conceptey elements here is the SideShow-esque e-ink display embedded in the laptop's lid, which promises to let you view your email, calendar, and other information even when the laptop's powered down. What's more, Intel also sees the entire laptop acting as a charging pad for your other gadgets, though it seems you'll still have to charge the laptop itself the old fashioned way. Even without those less-than-imminent additions, however, the laptop appears to be a pretty decent unit, measuing just 0.7 inches thick and packing a Core 2 Duo processor, along with Bluetooth, WiFi, and WiMAX connectivity.
