Hello—this is Ken Burns, reaching out on behalf of Alex Vindman for Senate.
I have dedicated my life to sharing America’s stories through films. They examine crucial moments in our nation’s history and the threats to our democracy. These stories are not easy.
Today, our country is facing its own reckoning, and the stakes have never been higher. That is why I am reaching out.

Abstract: This work presents a numerical investigation of soot formation in the Cambridge lab-scale gas turbine combustor. Large-eddy simulations (LES) of a swirl-stabilized ethylene flame are performed using the flamelet generated manifold method coupled with a discrete sectional model to account for soot formation, growth, and oxidation. The study aims to elucidate the mechanism governing the spatial structure and intermittency of soot, supported by comparisons with experimental data. The predicted soot distribution agrees well with measurements, with peak concentrations near the bluff body. Flow recirculation is identified as the key mechanism driving soot accumulation in fuel-rich regions, where surface reactions dominate soot mass growth. Soot intermittency arises from fluctuations in the flow field driven by interactions between the flame front and the recirculation vortex. Two soot modeling approaches are evaluated, differing in their treatment of soot model quantities: the first approach employs on-the-fly computation of source terms (FGM-C), while the second uses fully pre-tabulated source terms (FGM-T). Their predictive performance and computational cost are compared in the context of unsteady, sooting flames in swirl-stabilized combustors.

Conservatives want schools to teach this strict life path they say avoids poverty
The steps are simple: Graduate from high school. Find a full-time job. Get married before having kids.
The three-pronged framework is currently taught in just a handful of classrooms.
But soon, students across the country may be told that following those steps could keep them out of poverty as adults.
The approach is getting a boost from conservatives seeking to bring it to America’s middl…

In New York social circles, he was known as the “Jewish James Bond”:
a refugee from Nazi Germany whose gratitude to his American hosts was such that he volunteered to join the US army and became the CIA’s first station chief in Berlin as a mere twentysomething,
filing early warnings about Soviet activity that have been credited with ringing in the cold war.
Like 007, Peter Sichel also appreciated a fine tipple, and after leaving the US foreign intelligence service it was h…
With a stroke of his pen, Trump made the oil flow on behalf of Sable Offshore
— oil that hadn’t flowed for 10 years.
It began flowing from underwater oil wells located seven miles out to sea.
It flowed up to what used to be Exxon’s massive industrial plant along the Gaviota Coast.
And, ultimately, it flowed into two old pipelines that caused the 2015 massive oil disaster,
-- pipelines so corroded that Sable had to spend hundreds of millions of dollars to patc…
Oil prices have climbed again amid mounting supply fears after the US struck Iran’s vital Kharg Island oil hub and Donald Trump demanded allies help reopen the strait of Hormuz.
Brent crude, the international benchmark, rose 1.8% to $104.98 per barrel during early trading on Monday.
Another weekend of violence across the Middle East compounded concerns over the conflict, and its ramifications for global energy markets.
Trump claimed on Saturday that US strikes had “totally …
The scale of Orbšn’s defeat has left Moscow with little choice but to acknowledge the loss of a key partner in Europe.
“Hungary made its choice. We respect that choice,” Russian Foreign Minister Peskov said on Monday.
“We were never friends with Orbšn,” said Peskov,
adding that Moscow remained open to dialogue and to building good, mutually beneficial relations with Budapest.
Moscow appears to be playing down the loss of a key ally in Europe,
striking a tone rem…
U.S. Energy Secretary Chris Wright,
a former fracking executive,
was accused on Tuesday of manipulating global markets
after he posted a striking claim on social media:
The American Navy, he wrote, had “successfully escorted an oil tanker through the Strait of Hormuz to ensure oil remains flowing.”
The post on X was deleted minutes later,
after “oil prices slid at their steepest pace in years,” according to the Wall StreetJournal.
The White House pres…
