Ask Slashdot: Choosing a Laptop To Support Physics Research? 385

Posted by timothy
from the budget-for-replacement-too dept.
An anonymous reader writes My daughter is in her third year of college as a physics major. She has an internship in Europe this summer, will graduate next year, and continue with graduate physics studies. Her area of research interest is in gravitational waves and particle physics. She currently has a laptop running Win7 and wants to buy a new laptop. She would like to use Linux on it, and plans to use it for C++ programming, data analysis and simulations (along with the usual email, surfing, music, pictures, etc). For all of the physics-savvy Slashdotters out there: what should she get? PC? Mac? What do you recommend for running Linux? For a C++ development environment? What laptop do you use and how is it configured to support your physics-related activities?

I'd gladly give my life for a one-way trip for at least the guarantee of take-off and journey to Mars. Safe landing would be a bonus.

Jackpot would be a safe landing, lawn chair, 6-pack of beer fed through tube in the space suit.

Extra points for some days of stay and "science" work or prep work for the next round.

Scientists Insert a Synthetic Memory Into the Brain of a Sleeping Mouse 111

the_newsbeagle writes: Scientists are learning how to insert fake memories into the brain via precise electrical stimulation (abstract). In the latest experiment, they gave sleeping mice a synthetic memory that linked a particular location in a test chamber to a pleasurable sensation. (At least they gave the mice a nice memory.)

The researchers first recorded the electrical signals from the mice's brains while the mice were awake and exploring the test chamber, until the researchers identified patterns of activity associated with a certain location. Then, when the mice slept, the researchers watched for those neural patterns to be replayed, indicating that the mice were consolidating the memory of that location. At that moment, they zapped a reward center of the mice's brains. When the mice awoke and went back into the chamber, they hung around that reward-associated location, presumably expecting a dose of feel-good.

It is said in the movie that Rachel was "an experiment, nothing more". That she did not know what it was. This contrasts with the N6s which where in service. Not a mere experiment.

Doesn't explain why Leon likes his precious photos, giving that he what what he was. But that's not the only hole in the plot.
