e=mc2: 103 years later, Einstein's proven right

PARIS (AFP) – It's taken more than a century, but Einstein's celebrated formula e=mc2 has finally been corroborated, thanks to a heroic computational effort by French, German and Hungarian physicists.

A brainpower consortium led by Laurent Lellouch of France's Centre for Theoretical Physics, using some of the world's mightiest supercomputers, have set down the calculations for estimating the mass of protons and neutrons, the particles at the nucleus of atoms.

According to the conventional model of particle physics, protons and neutrons comprise smaller particles known as quarks, which in turn are bound by gluons.

The odd thing is this: the mass of gluons is zero and the mass of quarks is only five percent. Where, therefore, is the missing 95 percent?

The answer, according to the study published in the US journal Science on Thursday, comes from the energy from the movements and interactions of quarks and gluons.

In other words, energy and mass are equivalent, as Einstein proposed in his Special Theory of Relativity in 1905.

The e=mc2 formula shows that mass can be converted into energy, and energy can be converted into mass.

By showing how much energy would be released if a certain amount of mass were to be converted into energy, the equation has been used many times, most famously as the inspirational basis for building atomic weapons.

But resolving e=mc2 at the scale of sub-atomic particles -- in equations called quantum chromodynamics -- has been fiendishly difficult.

"Until now, this has been a hypothesis," France's National Centre for Scientific Research (CNRS) said proudly in a press release.

"It has now been corroborated for the first time."

For those keen to know more: the computations involve "envisioning space and time as part of a four-dimensional crystal lattice, with discrete points spaced along columns and rows."


Fancy Stuff

Weenie Dog

So, this is what really bored people do for fun.

Math Club Stupidity

So, they put a sign for a math club event on an area where no one can get it down, easily. However did this was either very tall or just otherwise very bored.

Supreme Nachos

Harvey's, the little mexican food joint down by the lakes between the HPR/Admin Building and the Library has the best nachos you can get for $3. They come with gooey cheese, your choice of beef or chicken, guacamole and sour cream, refried beans or pinto beans. Good stuff.


Nature shots - Because I was Bored

Halloween Fun

I know it's late, but I finally got it posted - also check down for some updated older entries.

I tried to do some nerdy pumpkins. I have tux the mascot of all things Linux and even nerdier, I put that the area of a circle = Pi r squared. Funny huh..

Elevator Outage

Not to be outdone by having a single elevator failure yesterday, now both elevators of the RBN are offline. Stuck on the first floor. This is too funny. I for one believe with the severity of these outages, about 1 or 2 a month, we should get this elevator recalled or be reimbursed. The elevator company should give back every cent this elevator cost and provide free service until it is repaired. This is simply unacceptable.

Connecting a network printer without a print server

I don't know if this works for all printers, but I got it to work with an HP P3005n.

Basic script:

rundll32 printui.dll,PrintUIEntry /if /b "printer" /f %windir%\dir\to\your\inf /r "http://IP/Hosname" /m "driver name" /Z

Example: (what actually seemed to work for me)

rundll32 printui.dll,PrintUIEntry /if /b "HP LaserJet P3005" /f %windir%\hp\hpc300xc.inf /r "" /m "HP LaserJet P3005 PCL 6" /Z

The kicked is you need to make sure that all the driver files are on the client pcs and you are good to go to use this script.

Some Randomness

David Tennant quits as Doctor Who

David Tennant is to stand down as Doctor Who, after becoming one of the most popular Time Lords in the history of the BBC science fiction show.

Tennant stepped into the Tardis in 2005, and will leave the role after four special episodes are broadcast next year.

He made the announcement after winning the outstanding drama performance prize at the National Television Awards.

"When Doctor Who returns in 2010 it won't be with me," he said.

"Now don't make me cry," he added. "I love this part, and I love this show so much that if I don't take a deep breath and move on now I never will, and you'll be wheeling me out of the Tardis in my bath chair."

'I'll miss it'

Three years was "about the right time" to play the role, he told the BBC in an exclusive interview.

"I think it's better to go when there's a chance that people might miss you, rather than to hang around and outstay your welcome," he said.

His stint in the show had been "the most extraordinary time, it's been bewildering, life changing, very exciting", he said.

"And just so much fun, such a great show to work on.

"That's one of the reasons I think it's right to take a deep breath and bow out when it's still fun, when it's a novelty.

"I don't ever want it to feel like a job, so I want to move on when it still feels exciting and fresh and that means I'll miss it."

Drama award

Tennant, the 10th actor to play the Doctor Who, left fans guessing about his return at the end of the latest series.

In the last episode, in July, the Doctor had to defeat his enemies the Daleks to save the universe.

Almost 10 million people watched as the Time Lord apparently started the process of regeneration - but did not complete it.

Tennant will appear in a Christmas special, titled The Next Doctor, before filming four more specials in January.

"They'll be the four last stories that I do," he said.

In a sign of his popularity, he was voted best drama performer in a public vote at the National Television Awards.

He has been named most popular actor at the same ceremony for the past two years. That prize has been discontinued this year.

An average of 8.1 million people a week watched the latest series - the fourth since it made a comeback in 2005 - in its Saturday evening slot on BBC One.

'Spectacular' exit

Russell T Davies, executive producer, said: "I've been lucky and honoured to work with David over the past few years - and it's not over yet, the Tenth Doctor still has five spectacular hours left!

"After which, I might drop an anvil on his head. Or maybe a piano. A radioactive piano. But we're planning the most enormous and spectacular ending, so keep watching."

A fifth series of the show is scheduled for 2010.

Tennant replaced Christopher Eccleston, who resurrected the show after a 16-year break.

Tennant made his name in TV dramas such as Blackpool and Casanova.

He started his career in theatre and in recent months has returned to the stage with well-received performances in Hamlet and Love's Labour's Lost for the Royal Shakespeare Company.

In December last year, Tennant denied rumours that he was planning to quit after Catherine Tate - his new companion in the Tardis - told the Jonathan Ross radio show she thought the next series of Doctor Who would be Tennant's last.

He said at the time: "Catherine Tate stitched me up good and proper. She goes on Jonathan Ross and makes up a load of old nonsense."

Do you ever notice no matter how things don't stay clean? Yet we spend so much money and time on cleaning supplies and cleaning things up. I find that as a species we are too caught up with being clean, although some lesser animals also like being clean, cats come to mind. Although people are clean discretely, in that they'll want one thing or another clean at time, rather than everything. Like say your kitchen could look super clean and sparkle and have a lemon scent, but your bedroom could be littered with dirty clothes and dishes. You know what I mean?

I just wonder why we clean everything so much. Why is our need for sterility so great. Are we so afraid of contracting some plague like disease? Or are we more afraid of what other people think? People who should not be judging us to being with. Did society create this stigma and are we stuck with it?

Research up and running!...almost...


All the machines in research are up and running. All the networking, works. I was more surprised at anyone, since I installed a good deal of it over the summer. There are now 64 Dell Optiplex systems, a mix of 620s and 280s. Plus 22 Solaris machines, 11 Ultra Sparc IIi systems and 11 newer systems. Not really sure what they are running.

Now we just need to get printing worked out, maybe. Oh and some racks and other misc. equipment.

I apologize if the picture suck, my phone camera is limited in its abilities.
