"2026" and nevertheless "could be"?

So Her Majesty's government is certainly not preparing anything similar to what J.F. Cooper called a "hasty pudding"...

Thus, High Speed Rail may or may not reach the Scottish border before the end of the current century, anybody willing to place a bet against that?

Comment: Anti-matter vs. dark matter (Score 2, Insightful) 113

by walter_f (#38146948) Attached to: Cosmic Antimatter Excess Confirmed

In my opinion and in contrary to what the original posting suggests, anti-matter should not be viewed as particularly "dark".

E.g., anti-Hydrogen, consisting of an anti-proton and a positron, will readily absorb a quantum of energy (a photon, which happens to be one of the particles that are their own anti-particles) and re-emit a photon again, just like "plain old" hydrogen. Thus, a cloud of anti-hydrogen should be observable as easily (or difficultly) as a cloud of hydrogen, assuming their masses, their viewing distances and all other parameters like temperature, density etc. being equal.

So there should be no difference in observability here, due to the fact that photons are citizens of both realms, of "nornal" matter as well as of anti-matter, and will interact with mass particles of both realms in the same way.

Obviously, "dark matter" looks like a very different beast...

But then, a can of the _original_ Budweiser (i.e., the one from the Czech Republic) would certainly achieve the coolness goal as well.

Including the taste goal. Many of the beers from Belgium or Ireland would do.

Just make sure to avoid those U.S. beverages that pretend to be "beer". Don't drink them, don't use their cans for your projects. ;-)

Comment: Calculus. Bertrand Russell. And Einstein himself. (Score 1) 358

First, you might start to enhance your understanding of advanced calculus.

At some early point along the road, get yourself a copy of
The ABC of Relativity, by Bertrand Russell, first ed. in 1925.
(Reading this book will just take the better part of a rainy day, breaks included. Enjoy it.)

Later on, read the Master's own writing:
Relativity. The Special and General Theory, by Albert Einstein, first ed. in 1920
http://www.bartleby.com/173/

Meanwhile, don't forget to continue your calculus efforts. ;-)

Remember, Einstein had a very pragmatic approach towards mathematics, he just used it.
To understand GR, you won't necessarily have to become more of a mathematician than Einstein wanted to be.

Anonymous releases 400 megs of FBI Contractor data->

Submitted by Anonymous Coward
An anonymous reader writes "Anonymous, as they have claimed they would, finally released 400 megabytes of files, allegedly stolen ManTech, a cyber security firm contracted by the FBI. Anonymous stated, 'The FBI is outsourcing cybersecurity to the tune of nearly $100 million to a Washington-area managed services company. The deal shows a willingness in the federal government to place IT services more and more in the hands of third parties as agencies don't have enough staff on hand to do the job.'

Best Off-Road Smart Phone? 5

rueger writes "I walk dogs for a living on the mountain trails above the North Shore of Vancouver. I rely on my smart phone for emergency contact, and use the GPS pretty constantly if I'm on unfamiliar trails. In general terms I like my Android smart-phone, and have fell in love with the platform. Problem is the cheapy Motorola Charm is a lousy phone with mediocre 3G reception, and GPS that can't always be relied upon unless you reboot regularly. That hasn't been an issue since the battery usually dies after five or six hours of use.

I'm opening a can of worms, but what's a good 3G Android phone with good reception in fringe areas, reliable GPS, and really good battery life? In other words, if you're heading for the woods, what's the tool that you rely on?

PS — don't like Apple products — 3 years with a Powerbook didn't convert me. And a good camera is a big plus."
