I think the primary issue is people using their credentials as a means of arguing from a position of authority. The “I have a Ph.D and you do not, therefore I’m right” rather than the “here’s my argument supported by this evidence, let’s discuss and find the truth.” In short, credentialism is bad, critical thinking is good. Don’t claim something is impossible unless it’s either self-evident or you do your own diligence. Credentialism is often conflated with academia where it is prolific, but it’s also present in other sectors too. The “I was a leader in a fortune 500 company for 20 years, therefore I how to run a deep tech startup better than you.” Just because you succeed in one arena doesn’t mean those skills are fit for purpose elsewhere without some adaptation / revision. We need to encourage evidence-based critical thinking across the board since that’s the only way to understand reality and what it can do. And that applies no matter where you’re working or what letters you may have after your name.
Do you think academics in STEM departments don’t get questioned and challenged? That they don’t have to test their hypotheses against data? People have a weird view of academia sometimes. Astrophysics isn’t a bunch of woke people sitting around chatting about stellar oppression.

Can confirm. Game changing technology. Having magnets from @CFS_energy operating at 17 T for months on end in a magnetic mirror really drives it home - the HTS age has arrived.
High-temperature superconductors won the Nobel Prize in 1987; it took decades for them to mature into a commercial product. Fusion is scaling global production to millions of km's per year Then the true explosion for HTS - Data Centers, Power Transmission, Generation

Happy Starship day to all who celebrate. 🚀💪
Now targeting Friday, July 24 for Starship’s thirteenth flight test, due to weather. A key objective for the flight test is to get clear imagery from the ground of Starship’s heatshield as it flies at a higher dynamic pressure during ascent, which won't be possible with today's weather conditions. Visibility is forecast to be ideal for a Friday attempt.

It’s clear that most students are missing the point of school. It’s not to get everything right on exams, it’s to learn how to think critically. An education system that overly “teaches to a test” is reinforcing this mistaken mindset about school as well. Learning how to think is the most adaptive and scalable skillset you should develop in school, and it’s not something you can or should outsource to AI. Why? It is the skillset that allows you to be the prime mover on new knowledge creation, and to diligence content from other people, whether in the form of posts, papers, books, talks, debates or LLM outputs. This issue predated LLMs but has become more pronounced in recent years. It’s easier to cheat using them, especially with the shift to take home exams during / after Covid. Nearly all of my exams in school were in-person, now speaking with students it seems in-person tests are an exception not the rule. Yes, in-person exams without access to any tools is not how work typically is in the real world. But again, the point of school is not to get everything right on an exam, it’s to demonstrate your ability to think and work through problems yourself. That’s why in-person testing is best in most cases to quantify your progress in developing this critically important ability. I argue that we should return to more in-person exams again. But that doesn’t address the root of the problem, which is orienting education towards the correct purpose. The point of school is to learn how to think critically, and this is not something that you can or should try to outsource to an LLM or anything or anyone else. It’s what makes you human and importantly individual capable of rigorous thought. With this skillset fully developed, humans can use amazing tools like LLMs to augment our abilities to scales previously impossible.
A Brown professor gave his students a take-home midterm exam. After suspecting many cheated using AI, he made the final in-person. The orange dots are the midterm scores and the gray dots are the final scores. Looks like all but 3 cheated on the midterm.

Turn: Washington’s Spies on AMC was also fantastic. One of the metrics I use to know a show was great is if I remember all the characters names and personal stories years later — this is one of those special shows: amcplus.com/shows/turn-washi…
Historical dramas like John Adams, Death by Lightning, and the Theodore Roosevelt one, all are better than most things you can access. Your History is more entertaining than fiction.

Highly recommend watching this film. It clearly depicts the radically different line of thought that pervades the founders of this country when you read their works. Yes, the world can be remade if you have the courage and will to do so — even a pawn can take a king .♟️👑🇺🇸
Today, 250 years ago, thirteen colonies declared their independence and became the United States of America. Celebrate America’s fight for freedom by seeing #YoungWashington in theaters now! 🇺🇸 @washingtonmovie @watchonwonder @2521ent

We recently demonstrated direct energy conversion (DEC) of plasma kinetic energy into electricity on our magnetic mirror device @RealtaFusion called WHAM! This is a small scale proof-of-concept of electrostatic DEC on the 100s of watts scale enough to light up a few lightbulbs.
⚡ Realta just demonstrated direct electricity conversion from a fusion reaction, the first company to do so. This direct conversion is 90% efficient versus ~33% efficiency for the typical setup using heat to drive a steam turbine. techcrunch.com/2026/06/30/re…

This higher efficiency will allow net-electric power production at a lower plasma gain, and make the prospect of advanced fusion fuel cycles (i.e. catalyzed D-D and D-3He) even more compelling — more charged fusion product kinetic energy directed converted into electricity.

We certainly can debate on the best way to introduce people to markets and investing, but it certainly needs to be done. I’m genuinely floored by how many I know who have no investments besides cash because the market is just “gambling”. Such huge missed opportunities.
Trump accounts aren't just free money for kids. They're a forced introduction to markets. The kid who watches $1,000 grow is less likely to fear capitalism as an adult.

The speed @bscholl got this into the store is just one small example of why I’m confident we’ll be able to buy tickets to fly on Overture very soon. Onward @boomsupersonic! 🦅🇺🇸✈️💪🏻
At the suggestion of @dasutherland, Boom is making beautiful America 250 Overture desktop models for $250. Order link below.

Happy 250th anniversary to the greatest country on Earth that is built on some of the most important ideas in human history: the individual rights of life, liberty and the pursuit of happiness. Celebrate this revolutionary thought today and the ongoing pursuit of it!

Welcome home! Glad to see a perfect splash down and having everyone back home safe and sound after an epic journey. Nice work @NASA!
Replying to @NASA
Welcome home Reid, Victor, Christina, and Jeremy! 🫶 The Artemis II astronauts have splashed down at 8:07pm ET (0007 UTC April 11), bringing their historic 10-day mission around the Moon to an end.

Great news for Californians! At least twenty more years of clean, safe, and reliable power from Diablo Canyon.
#NRCNews:✅We've renewed the operating licenses of the Diablo Canyon Nuclear Power Plant for an additional 20 years, marking the 99th and 100th renewed commercial reactor operating licenses. nrc.gov/sites/default/files/…
