Should we expect a new revolution in physics, this time with logic arguments and not for justifying huge funds with flipping coins and counting particles (link)? Here’s a recent paper describing how gravity can be considered a consequence of the information, not as a fundamental force. In my humble opinion, this idea has the necessary beauty to kick us beyond Einstein’s general relativity.

it’ll be a busy summer. just ordered a launchpad msp430, a maple (rev5), a fez domino from watterott electronic. already have a propeller platform sd and plenty of arduino. i’m trying to choose the best platform for next year’s lectures.
playing with an arduino and a few boards i’ve got from watterott i needed a simple solution for safely connecting the 3.3V boards to the 5V arduino’s I2C/TWI interface. searching the web i’ve found an article addressing this problem without using some unavailable chips. the solution uses 4 general purpose NPN transistors and 6 resistors. i’ve built and tested the bi-directional level shifter and it worked fine getting data from a ITG3200 gyro, an ADXL345 accelerometer and a HMC5843 magnetometer, all connected at once.
got the reply from cern. «unfortunately we have not been able to offer you a position at this stage. however, we have put your name on the list of reserve candidates in the event that a position becomes available»
