Physics in Trouble: Why the Public Should Care

botelho says...

Refreshness on theoretical physics should be always welcome , however to be technically careful with new proposals is mandatory !

The E8 pattern (click to enlarge), Garrett Lisi surfing (middle) and out of the water (right)
An impoverished surfer has drawn up a new theory of the universe, seen by some as the Holy Grail of physics, which has received rave reviews from scientists.
• Garrett Lisi: This surfer is no Einstein...
• Test tube universe hints at unifying theory
• Surfer Dude's Theory of Everything - The Movie
Garrett Lisi, 39, has a doctorate but no university affiliation and spends most of the year surfing in Hawaii, where he has also been a hiking guide and bridge builder (when he slept in a jungle yurt).

In winter, he heads to the mountains near Lake Tahoe, Nevada, where he snowboards. "Being poor sucks," Lisi says. "It's hard to figure out the secrets of the universe when you're trying to figure out where you and your girlfriend are going to sleep next month."
Despite this unusual career path, his proposal is remarkable because, by the arcane standards of particle physics, it does not require highly complex mathematics.
Even better, it does not require more than one dimension of time and three of space, when some rival theories need ten or even more spatial dimensions and other bizarre concepts. And it may even be possible to test his theory, which predicts a host of new particles, perhaps even using the new Large Hadron Collider atom smasher that will go into action near Geneva next year.
Although the work of 39 year old Garrett Lisi still has a way to go to convince the establishment, let alone match the achievements of Albert Einstein, the two do have one thing in common: Einstein also began his great adventure in theoretical physics while outside the mainstream scientific establishment, working as a patent officer, though failed to achieve the Holy Grail, an overarching explanation to unite all the particles and forces of the cosmos.
Now Lisi, currently in Nevada, has come up with a proposal to do this. Lee Smolin at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, Canada, describes Lisi's work as "fabulous". "It is one of the most compelling unification models I've seen in many, many years," he says.
"Although he cultivates a bit of a surfer-guy image its clear he has put enormous effort and time into working the complexities of this structure out over several years," Prof Smolin tells The Telegraph.
"Some incredibly beautiful stuff falls out of Lisi's theory," adds David Ritz Finkelstein at the Georgia Institute of Technology, Atlanta. "This must be more than coincidence and he really is touching on something profound."

• Quantum genesis: How life was born on Earth
The new theory reported today in New Scientist has been laid out in an online paper entitled "An Exceptionally Simple Theory of Everything" by Lisi, who completed his doctorate in theoretical physics in 1999 at the University of California, San Diego.
He has high hopes that his new theory could provide what he says is a "radical new explanation" for the three decade old Standard Model, which weaves together three of the four fundamental forces of nature: the electromagnetic force; the strong force, which binds quarks together in atomic nuclei; and the weak force, which controls radioactive decay.
The reason for the excitement is that Lisi's model also takes account of gravity, a force that has only successfully been included by a rival and highly fashionable idea called string theory, one that proposes particles are made up of minute strings, which is highly complex and elegant but has lacked predictions by which to do experiments to see if it works.
But some are taking a cooler view. Prof Marcus du Sautoy, of Oxford University and author of Finding Moonshine, told the Telegraph: "The proposal in this paper looks a long shot and there seem to be a lot things still to fill in."
And a colleague Eric Weinstein in America added: "Lisi seems like a hell of a guy. I'd love to meet him. But my friend Lee Smolin is betting on a very very long shot."
Lisi's inspiration lies in the most elegant and intricate shape known to mathematics, called E8 - a complex, eight-dimensional mathematical pattern with 248 points first found in 1887, but only fully understood by mathematicians this year after workings, that, if written out in tiny print, would cover an area the size of Manhattan.
E8 encapsulates the symmetries of a geometric object that is 57-dimensional and is itself is 248-dimensional. Lisi says "I think our universe is this beautiful shape."

What makes E8 so exciting is that Nature also seems to have embedded it at the heart of many bits of physics. One interpretation of why we have such a quirky list of fundamental particles is because they all result from different facets of the strange symmetries of E8.
Lisi's breakthrough came when he noticed that some of the equations describing E8's structure matched his own. "My brain exploded with the implications and the beauty of the thing," he tells New Scientist. "I thought: 'Holy crap, that's it!'"
What Lisi had realised was that he could find a way to place the various elementary particles and forces on E8's 248 points. What remained was 20 gaps which he filled with notional particles, for example those that some physicists predict to be associated with gravity.
Physicists have long puzzled over why elementary particles appear to belong to families, but this arises naturally from the geometry of E8, he says. So far, all the interactions predicted by the complex geometrical relationships inside E8 match with observations in the real world. "How cool is that?" he says.
The crucial test of Lisi's work will come only when he has made testable predictions. Lisi is now calculating the masses that the 20 new particles should have, in the hope that they may be spotted when the Large Hadron Collider starts up.
"The theory is very young, and still in development," he told the Telegraph. "Right now, I'd assign a low (but not tiny) likelyhood to this prediction.
"For comparison, I think the chances are higher that LHC will see some of these particles than it is that the LHC will see superparticles, extra dimensions, or micro black holes as predicted by string theory. I hope to get more (and different) predictions, with more confidence, out of this E8 Theory over the next year, before the LHC comes online."

Sadat X - Hang'em High

MrFisk says...

A lot of niggaz stepped up to the bad man
Chest bucked out with your head wide open
Hopin, to spot, a chip in this frame
I lived and died by the burnin flame
of the OK Corral, Cowboy style
From the Quarters on down to Colorado's
Big niggaz from uptown, ridin into Tahoe's
Saloon settin, kids is walkin round
drinkin whiskey and scotch, strictly out of shotglasses
Lookin screwfaced at the next nigga who passes
There's women in garter belts and ciggarettes
And on the side there's the price game
Niggaz is playin the price game
Indian Red, was bangin niggaz in the head
With his man Apache Joe, they take your money off the floor
They side-bettin for a better, they makin cheddar
That tribal shit is work ya sound the wompom drums
Cause my Indian man'sll break your great dick, UHH
Walk in the New York terrority
On the back of a tree, there's a picture of me
It says I'm lawless, flawless, a hustler plus gun rustler
Wanted in Carolina, for sellin some of New York's finer
Marshal Cooper say he want me, Marshal Cooper gotta get me
Marshal Cooper say beat me, Marshal Cooper better wet me
I gather alla y'all, all of my trusted men
All of my baddest niggaz, niggaz that's quickest with the triggers
There's distrubin news on the wire
That my dome piece is done sent to piece out for hire
I ain't goin down over no money exchange
You late for say I, who reigns as King of the Range?
In this land of wildness
Yo you better pack your vest
In the streets there's nothin but crime
So you best to watch your behind...
Meanwhile saloon settin is back to full swing
Bar's gettin money people doin they thing
There's strictly Boss Players with this kid named Minnesota
As women start to fill up, turn the notch on the grill up
And add mo' stakes to the house banks for gamblers
Half-pipes to scramblers, and free for Wild Cowboys
You never bring decoys if you wanna make real nouse
The bigger the stick, the bigger the fire
I never hit a man in the back, a coward acts like that
Lay out my black hat cause I feel like the bad man
Who on the rise, the D's to Manhattan
Let's walk the thirty paces on the Now Rule races
Oh it's the Marshal Cooper, and I love how he doin this
Women sayin don't get hurt, and I ain't plannin on it
Ten steps taken as I hit the blam factor
His dick to act up, was death the benefactor
Leave him twitchin in the dirt like Cousin Harold from the Menace
I'm in this to win this on the great wide trail
I'm ten times as bad as John Wayne, could ever be
Plus I'm down with the Indian, and need high to get the shit again
I'm responsible for that body in the alley
I'll Louisiana Purchase that ass with with Remi's spurs
and hard shots of Tequila, where the dancin girls
Let's get right as the story unfurls
Piano man keep playin, keep them keys bangin
Single man get three graves there's gonna be a hangin
Now this right here ain't for the youth to see
A grown man assed out swingin from a tree
In this land of wildness
Yo you better pack your vest
In the streets there's nothin but crime
So you best to watch your behind
Joe Tex was the biggest hombre from the projects
Had all the work locked down, so he thought
But he drank and got loose lipped, let a lot of news slip
Stripped of his game and got his self murdered
Thoughts of him are passin like the buffalo
Got his self rocked in the ninety-six brand new Acura
Niggaz said it was lightning BLAOW blew out the back mirror
Hah, youknowhatI'msayin? Dig, check it out
They say that Cowboys never die they just ride off into the sun
A little tale from Sadat X of how the WORLD was won
Check it out, remember this
Gun-slingers, dead-ringers with presidents
Is found tied with no explanation of how they died
Yo the great Sadat X, the High Plains Drifter
No question
In this land of wildness
Yo you better pack a vest
In the streets there's nothin but crime
So you best to watch your behind

25 Random things about me... (Blog Entry by youdiejoe)

kagenin says...

Yeah, I know it's been a while since someone last posted here, but I feel like sharing.

1) I was once ranked in the top 150 ExpertCTF for Quake2 players in the world by TheCLQ.com, and I did it on dial-up.

2) I am only a few credits shy of getting an AA. I don't consider myself a drop-out, but it has been a very long time since I was in school.

3) Every girl I've been with ranks me somewhere between "really awesome" and "the best they ever had" in bed.

4) I once got my car stuck in the middle of Tahoe National Forest.

5) I used to be a boy scout.

6) Both my girlfriend and I have an aversion to using firearms.

7) I sleep with a very sharp 18" black ninja sword next to my bed.

I once did security for a Taj Mahal concert. I got him and his band to sign my badge.

9) Like many other sifters I've also worked in community theater, mostly backstage work.

10) I've studied martial arts off and on, since I was 8. I have 4 years of experience in American Kempo Karate (the stuff Ed Parker taught Elvis), and 4 years of Aikido training. Aikido had a bigger impact on my life.

11) When I was in 8th grade, my Odyssey of the Mind team came in Second place in regional competition. Only our teacher's team did better than us in our category. I wore a tiger costume (an orange jumpsuit I made, and then drew stripes on).

12) For about 4 years, I worked in a place Mark Twain, and two presidents once slept.

13) My parents own a Yellow-naped Green Amazon parrot. I'll likely inherit him. He's been in the family since I was in 4th grade.

14) I have never had any urge to join the military.

15) I've walked through the red light district in Amsterdam.

16) As a waiter, I once served the author of Schindler's List.

17) I've had long hair for most of my life.

18) I enjoy dueling friends using a Shinai - a traditional bamboo training sword.

19) I'm addicted to Yahoo! Answers. It's sad, but there's so many noobs who need schooling. I got to level 6 answering a bunch of the same questions in the Wii category.

20) I used to have a pet Goose.

21) I didn't sleep at all last night.

22) I was told many times growing up I could have been a model. I would rather be known for contributing something more to the world than just my looks, though, so I never pursued it.

23) I have mastered the head-stall footbag technique.

24) I don't kick footbag as much since rolling my ankle a couple years ago.

25) When I was in 1st grade, my dad would sometimes guest host for a friend's late night community radio program. The couple times he took me along were awesome.

Hackers Orbital - Halcyon - Mashup

Halon50 says...

Oh oops, forgot the trivial "in my day" comment!

In my day, after watching the movie, I went out and got the soundtrack, the Hackers 2 CD, and later the Hackers 3 CD which I think I tossed. Anyway the Hackers and Hackers 2 discs became the beginning of my downward spiral into Techno hell. I remember listening to the #2 CD over and over again during a snowboarding trip to Tahoe/Donner. Great stuff!

My Eye Just Popped Out!
