In the fall of 2022, a Princeton University graduate student named #Carolina #Figueiredo
stumbled onto a massive coincidence.

She calculated that collisions involving three different types of subatomic particles would all produce the same wreckage.

“They are very different [particle] theories.
There’s no reason for them to be connected,” Figueiredo said.

The coincidence soon revealed itself to be a conspiracy:

The theories describing the three types of particles were,
when viewed from the right perspective,
essentially one.

The conspiracy, Figueiredo and her colleagues realized, stems from the existence of a hidden structure,
one that could potentially simplify the complex business of understanding what’s going on at the base level of reality.

For nearly two decades, Figueiredo’s doctoral advisor, #Nima #Arkani-#Hamed
has been leading a hunt for a new way of doing physics.

Many physicists believe they’ve reached the end of the road when it comes to conceptualizing reality in terms of quantum events that play out in space and time.

Such language can’t easily describe the beginning of the universe, for instance,
when the space-time fabric likely didn’t exist in its current form.

Arkani-Hamed therefore suspects that the usual notion of quantum particles moving and interacting in space-time is an approximation of deeper, more abstract concepts,
which, if found, could serve as a better language for talking about quantum gravity and the origin of the universe.

A major development came in 2013, when Arkani-Hamed and his student at the time, #Jaroslav #Trnka, discovered a jewel-like geometric object that forecasts the outcome of certain particle interactions.

They called the object the “#amplituhedron.”

However, the object didn’t apply to the particles of the real world.
So Arkani-Hamed and his colleagues sought more such objects that would

Figueiredo’s conspiracy is another manifestation of abstract geometric structure that seems to underlie particle physics.

“The overall program is inching closer to Nima’s long-term dream of space-time and quantum mechanics emerging from a new set of principles,”
said Sebastian Mizera, a physicist who studies amplitudes at the Institute for Advanced Study in Princeton, New Jersey, but was not involved in the recent work.

Like the amplituhedron, the new geometrical method,
known as “#surfaceology,” streamlines quantum physics by sidestepping the traditional approach,
which is to track the countless ways particles can move through space-time using “Feynman diagrams.”

These depictions of particles’ possible collisions and trajectories translate into complicated equations.

With surfaceology, physicists can get the same result more directly.

“It provides a natural framework, or a bookkeeping mechanism,
to assemble very large numbers of Feynman diagrams,” said #Marcus #Spradlin, a physicist at Brown University who has been picking up the new tools of surfaceology.

“There’s an exponential compactification in information.”

Unlike the amplituhedron,
which required exotic particles to provide a balance known as supersymmetry,
surfaceology applies to more realistic, nonsupersymmetric particles.

“It’s completely agnostic. It couldn’t care less about supersymmetry,” Spradlin said.

“For some people, me included, I think that’s really been quite a surprise.”

The question now is whether this new, more primitive geometric approach to particle physics will allow theoretical physicists to slip the confines of space and time altogether.

“We needed to find some magic, and maybe this is it,” said #Jacob #Bourjaily, a physicist at Pennsylvania State University.

“Whether it’s going to get rid of space-time, I don’t know.
But it’s the first time I’ve seen a door.”

The top House GOP super PAC is dropping another💥 $12 million on TV ads to help Republican candidates from getting swamped by their Democratic opponents.
The Congressional Leadership Fund’s buys, shared first with POLITICO, are largely defensive and meant to help incumbents in tough districts. Here’s a breakdown of where they’re spending:
• Reinforcements in #California:Some $3.6 million is headed toward the Los Angeles market where GOP Reps. Mike Garcia, Michelle Steel and Ken Calvert are locked in competitive races. Another $765,000 will go in the Fresno and Sacramento markets for GOP Rep. John Duarte.
• Shoring up #New #York: CLF is adding $600,000 in the Albany, Binghamton and Syracuse markets that cover the districts of GOP Reps. Marc Molinaro and Brandon Williams. 
• Defense in #Iowa: The new buys include $635,000 across the Des Moines and Cedar Rapids markets to boost Republican Reps. Zach Nunn and Mariannette Miller-Meeks. 
• New spends in #Pennsylvania:CLF is dropping $2.6 million to help Republican Rep. Scott Perry in Harrisburg, Pennsylvania. He faces a stiff challenge from Janelle Stelson, a former TV news anchor. This is CLF’s first ad spend in the district. 
• Offense in #North #Carolina: The super PAC is dropping $1.4 million more in the North Carolina district of Democratic Rep. Don Davis to help Republican Laurie Buckhout. 

The group is also slotting another 💥$1.5 million toward ads on streaming services, including in the districts of Rep. John James (R-#Mich.) and Derrick Van Orden (R-#Wis.).

There are really only three states that will decide the presidential election: #Pennsylvania, #North #Carolina and #Georgia.

💥If Vice President Kamala Harris can’t carry Pennsylvania, her only hope is on a Southern strategy.

Harris must win either Georgia or North Carolina.
She has no other path to the White House.
The election could well be determined when polls close in the eastern time zone.

(Well, yes, after the ballots are all counted.
-- Which is why Allies of Donald Trump who control the #Georgia State #Election #Board approved a controversial
👉new rule Friday requiring counties to
💥hand-count 💥the number of ballots cast at polling places on Election Day,
❌despite bipartisan objections from election officials and poll workers!)

All this isn’t to say the other four battlegrounds
— #Michigan, #Wisconsin, #Nevada and #Arizona
— aren’t important.

If Harris loses Pennsylvania, which her aides acknowledge is a highly challenging state,
she’d still need to pick up one of the two Western states as well as one of the two Southern states to win
— so long as she carries Michigan and Wisconsin.

Yet none of those other four battlegrounds are relevant if Trump first blocks her in Pennsylvania, Georgia and North Carolina.

It’s the most obvious route for the former president and a reminder of the advantage the Electoral College can confer on a Republican.

Today was another goal fest for #Carolina. #Raleigh. The game started quite off for the #canes, getting several penalties & not getting the PK done. In the 2nd period, the momentum shifted & Seely opened the score for the canes prospects. Then, the 3rd period happened, with Gleb Trikozov scoring 3 goals for a hat trick. Carolina wouldnt give up the lead again. Final score 7 to 3. Concluding with picture of goalie Perets with 38 stops on 42 shots including stopping 4 of 5 in shootout #nhl #hockey

Carolina has a really good group of prospects. That Felix Unger Sorum, Bradly Nadeau and Noel Gunler line really was interesting to watch tonight. After the final 7-4 scores for Hurricanes prospects, they also featured a shootout, 2-1 carolina. Bradly Nadeau scored one, and i forgot to write down who scored the other. Sorum or Gunler, w/ quick pace change. I think also that Antonin Verreault who scored the first goal showed a lot of grit.

Scoreboard, final Carolina 7, Tampa Bay 4

Trump is giving up and pulling out of three states.

He’s bailing on #New #Hampshire, #Virginia, and #Minnesota.

Trump was never likely to win any of these states. But his campaign viewed them as being just competitive enough that an upset might be possible in each of them.

No more. It’s even worse for him than that.

While Trump hasn’t pulled out of #Michigan or #Wisconsin, he’s now spending the minimum in those states, suggesting he doesn’t think he can win them either.

It appears he’s trying to win the Electoral College by winning #Pennsylvania, #North #Carolina, and #Nevada.

This is a dangerous strategy for him, because it means
🔥Kamala Harris can defeat him simply by winning any one of those three states.

And if she does, Trump no longer has any fallback scenario.

Noncitizen voting cases filed in North Carolina, Michigan and Wisconsin

The #RNC 💥filed two more anti-voting lawsuits💥 this week,

alleging #North #Carolina has failed to remove noncitizens from its voter rolls

and claiming that #Detroit, Michigan, has unlawfully hired more Democrats than Republicans to be poll workers.

A #Wisconsin voter filed a lawsuit claiming that the state is not properly verifying the citizenship status of people registering to vote and is violating state law.

Harris Puts Four Sun Belt States Back in Play, Times/Siena Polls Find

Kamala Harris and Donald Trump are in close races across #Arizona, #Georgia, #Nevada and #North #Carolina -- crucial swing states that Donald Trump had seemed en route to run away with just a few weeks ago

Last week, Times/Siena polling showed that Ms. Harris had pulled ahead of Mr. Trump by a narrow margin in the three northern battleground states of #Michigan, #Pennsylvania and #Wisconsin.

Those states are generally considered the linchpin of any Democratic path to the White House.

-- The Sun Belt represents an essential set of states for Trump while offering a potential second route for Harris to the 270 Electoral College votes needed to win.
