Princeton professor Eddie Glaude and Commentary's Noah Rothman argue/MSNBC screen shot
Conservative commentator Noah Rothman found himself on Princeton professor Eddie Glaude's bad side in a Monday appearance on MSNBC, where he was taken to task for "ignoring history" when he played down the three black churches that were burned to the ground in Louisiana over the past ten days.
"Our history always haunts," Glaude said. "There are these incidents, events that happen in our lives that trigger history, a history that we haven't gotten beyond. So, to see churches burn, it strikes at the heart of the ugliness of who we are -- not who we were, but who we are."
Rothman put on his aggrieved face and asked to respond.
"These are heinous crimes, and we should treat them like heinous crimes," he said, and then proceeded to try to minimize them.
"But in 2016, you had two -- an arson attack and a vandalism attack on black churches, the intent was to make people think the bad old days were well and truly back," he continued as Glaude began shaking his head. "And that's what was broadcast, the pervasive effort by these people was to make us think that this was the result of Donald Trump's election."
"This is not responsible for you to take statistically insignificant moments and read them write large over the course of American history," Glaude said. "Yet in your book and in this moment, you want to generalize it to call into question a basic point that I was making -- that when you see something like this, it triggers history."
"Part of what you have to do, Noah, when you make these sorts of moves is to understand what you're minimizing in that moment," Glaude went on. "History haunts. The thing is that you don't want to take seriously that history.
Reacting to the growing wave of bad news on the legal front for Donald Trump, former U.S. Attorney Barbara McQuade claimed the hits keep coming for the former president and that they are accelerating because judges can see through Trump's delay game.
Speaking with MSNBC host Jonathan Capehart on Saturday morning, McQuade claimed she was stunned by a judge ordering the DOJ to respond to a motion first thing the next morning and claimed it was indicative of what the former president can expect as multiple indictments in multiple jurisdictions loom.
"Am I reading too much into it, by how quickly that court made this determination?" host Capehart prompted. "Where Judge Beryl [Howell] says, 'no attorney-client privilege,' then the new chief judge comes in says, 'hey, wait a minute,' then almost immediately says, 'oh no, Trump attorneys, you've got until midnight. [Special counsel] Jack Smith, you've got until six am to respond to the midnight filing.' That is, in and of itself, a significant development."
"That is the most extraordinary briefing schedule I've ever heard in my life," McQuade admitted. "The Justice Department had between midnight and 6 am to file their response? I've never seen anything like that. I don't know the reason."
"It could be that they don't want Donald Trump dragging his feet — it could be that there was something occurring there that they were needing to beat that's not known to the public," she explained. "It could even be that the documents had already been turned over, and so, they were trying to avoid a scenario where there was a reversal after the horse was out of the barn, so to speak."
"I don't know, but it does seem that judges are getting Trump's number, in terms of not giving him a lot of time to delay the quest for justice," she added.
Gov. Ron DeSantis (R-FL) has yet to jump into the race for the Republican party's 2024 presidential nomination, and there are growing indications that he may not be able to pull away a substantial segment of Donald Trump supporters that would allow him to not only beat the former president in the GOP primaries but also win in a general election.
According to a report from Politico's Steven Shepard, DeSantis is going through all of the motions of running for president, without actually announcing, but he is running into speedbumps when it comes to rallying conservative voters to his camp.
Put simply by Shepard, DeSantis' presidential drive has "hit the skids."
What should be of concern to the DeSantis camp is the inability to pull away what are now being called "beer track" voters, described as having "lower incomes and levels of educational attainment," who have strongly allied themselves with the former president.
As the Politico report notes, it's getting worse for the high-profile Florida governor.
"While DeSantis is still the preferred candidate of high-income voters and those with college degrees, he is showing signs of bleeding there, too. In recent weeks, Trump’s numbers have been rising among all Republicans, including with GOP voters most skeptical of his candidacy in the so-called 'wine track,'" Shepard is reporting.
"It’s obviously still early in the 2024 contest: DeSantis isn’t even a declared candidate yet, and most of the new polls were conducted prior to the news that Trump may soon face criminal charges in New York related to an alleged hush-money payment he made during his 2016 campaign to hide an extramarital affair. Other potential legal troubles loom on the horizon," he continued before adding, "But even if the campaign hasn’t officially started, the recent polling trends do provide positive data for Trump and troubling numbers for DeSantis."
"For now, however, the greatest divide with potential to define the 2024 Republican primary is class. Don’t expect the most educated Republicans to fall in love with Trump, or the 'beer track' to abandon him en masse. But any marked shifts among these groups in the coming months could make the difference," he predicted.
The modern world runs on electricity, and wires are what carry that electricity to every light, television, heating system, cellphone and computer on the planet. Unfortunately, on average, about 5% of the power generated at a coal or solar power plant is lost as the electricity is transmitted from the plant to its final destination. This amounts to a US$6 billion loss annually in the U.S. alone.
For decades, scientists have been developing materials called superconductors that transmit electricity with nearly 100% efficiency. I am a physicist who investigates how superconductors work at the atomic level, how current flows at very low temperatures, and how applications such as levitation can be realized. Recently, researchers have made significant progress toward developing superconductors that can function at relatively normal temperatures and pressures.
To see why these recent advances are so exciting and what impact they may have on the world, it’s important to understand how superconducting materials work.

A resistance-free material
A superconductor is any material that conducts electricity without offering any resistance to the flow of the electric current.
This resistance-free attribute of superconductors contrasts dramatically with standard conductors of electricity – like copper or aluminum – which heat up when current passes through them. This is similar to quickly sliding your hand across a smooth, slick surface compared to sliding your hand over a rough rug. The rug generates more friction and, therefore, more heat, too. Electric toasters and older-style incandescent lightbulbs use resistance to produce heat and light, but resistance can pose problems for electronics. Semiconductors have resistance below that of conductors, but still higher than that of superconductors.
Superconductive materials repel magnetic fields, making it possible to levitate a magnet above a superconductor.
Another characteristic of superconductors is that they repel magnetic fields. You may have seen videos of the fascinating result of this effect: It is possible to levitate magnets above a superconductor.
How do superconductors work?
All superconductors are made of materials that are electrically neutral – that is, their atoms contain negatively charged electrons that surround a nucleus with an equal number of positively charged protons.
If you attach one end of a wire to something that is positively charged, and the other end to something that is negatively charged, the system will want to reach equilibrium by moving electrons around. This causes the electrons in the wire to try to move through the material.
At normal temperatures, electrons move in somewhat erratic paths. They can generally succeed in moving through a wire freely, but every once in a while they collide with the nuclei of the material. These collisions are what obstruct the flow of electrons, cause resistance and heat up the material.
The nuclei of all atoms are constantly vibrating. In a superconducting material, instead of flitting around randomly, the moving electrons get passed along from atom to atom in such a way that they keep in sync with the vibrating nuclei. This coordinated movement produces no collisions and, therefore, no resistance and no heat.
The colder a material gets, the more organized the movement of electrons and nuclei becomes. This is why existing superconductors only work at extremely low temperatures.
If scientists can develop a room-temperature superconducting material, wires and circuitry in electronics would be much more efficient and produce far less heat. The benefits of this would be widespread.
If the wires used to transmit electricity were replaced with superconducting materials, these new lines would be able to carry up to five times as much electricity more efficiently than current cables.
The speed of computers is mostly limited by how many wires can be packed into a single electric circuit on a chip. The density of wires is often limited by waste heat. If engineers could use superconducting wires, they could fit many more wires in a circuit, leading to faster and cheaper electronics.
Finally, with room-temperature superconductors, magnetic levitation could be used for all sorts of applications, from trains to energy-storage devices.
With recent advances providing exciting news, both researchers looking at the fundamental physics of high-temperature superconductivity as well as technologists waiting for new applications are paying attention.
