Insane stat of the day: California almonds use roughly 3–5.5 million acre-feet of water per year, depending on methodology.
That's ~4-7x more water than all data centers in North America used combined in 2025.
An MIT professor taught the same math course for 62 years, and the day he retired, students from every country on earth showed up online to watch him give his final lecture.
I opened the playlist at 2am and ended up watching three of them back to back.
His name is Gilbert Strang. The course is MIT 18.06 Linear Algebra.
Every machine learning engineer, every data scientist, every quant, every self-taught programmer who actually understands how AI works learned the math from this one man. Most of them never set foot on MIT's campus. They just opened a free playlist on YouTube and let him teach.
Here's the story almost nobody tells you.
Strang joined the MIT math faculty in 1962. He retired in 2023. That is 61 years of standing at the same chalkboard teaching the same subject to 18-year-olds.
The interesting part is what he did when MIT launched OpenCourseWare in 2002. Most professors were skeptical. They worried that putting their lectures online would make their classrooms irrelevant. Strang did not hesitate. He said his life's mission was to open mathematics to students everywhere. He filmed every lecture and gave it away.
The decision quietly changed how the world learns math.
For decades linear algebra was taught the wrong way. Professors started with abstract vector spaces and proofs about field axioms. Students drowned in the abstraction. Most never recovered. They walked out believing they were bad at math when they had simply been taught in an order that nobody's brain is built to absorb.
Strang inverted the entire curriculum.
He started with matrix multiplication. Something you can write down on paper. Something you can compute by hand. Something you can see. Then he showed his students that everything else in linear algebra eigenvectors, singular value decomposition, orthogonality, the four fundamental subspaces was just a different lens for understanding what the matrix was actually doing under the hood.
His rule was strict. If a student could not explain a concept using a concrete 3 by 3 example, that student did not actually understand the concept yet. The abstraction was supposed to come last, not first. The intuition was the foundation. The proofs were just confirmation that the intuition was correct.
The second thing Strang changed was the classroom itself. He said please and thank you to his students. Every single lecture. He paused mid-derivation to ask "am I OK?" to check if anyone was lost. He never used the word "obviously" or "trivially" because he knew exactly what those words do to a student who is one step behind. He treated 19-year-olds learning math for the first time the way he treated his own colleagues. With patience. With respect. With the assumption that they belonged in the room.
For 62 years.
The result is something that has never happened in the history of education. A single math professor became the default teacher of his subject for the entire planet.
Universities in India, China, Brazil, Nigeria, every country with a computer science department, started telling their own students to just watch Strang's lectures. The University of Illinois revised its linear algebra course to do almost no in-person lecturing. The reason was honest. The professor said they could not compete with the videos.
His final lecture was in May 2023.
The auditorium was packed with students who had never met him before. He walked to the chalkboard, taught for an hour, and at the end the entire room stood and applauded. He looked confused for a moment, like he genuinely did not understand why they were cheering. Then he smiled and waved them off and walked out.
His written comment under the YouTube video of that final lecture was four sentences long. He said teaching had been a wonderful life. He said he was grateful to everyone who saw the importance of linear algebra. He said the movement of teaching it well would continue because it was right.
That was it. No book promotion. No farewell speech. No legacy management.
The man whose teaching is the foundation of modern AI just thanked the audience and went home.
20 million views. Zero ego. The entire engine of the AI revolution sits on top of math that millions of people learned for free from one quiet professor in Cambridge.
The course is still on MIT OpenCourseWare. Every lecture, every problem set, every exam, every solution. Free.
The most important math course of the 21st century is sitting one click away from you. Most people will never open it.
Imagine you are a working father living in the Midwest, you make 75k a year. You can support your family, but you're not rich. You worry about paying for college. Then you read about some Somalian stealing $1m out of federal healthcare programs.
$1 million for the normal guy would eliminate an enormous amount of his stress. The college thing would be covered. Retirement wouldn't appear so daunting. It's why guys like this buy lottery tickets. And instead he pays into the system and watches "newcomers" make a complete ass out of him. This fraud is bad financially, but it just makes a mockery of all the hard work of normal people and tears away at the social fabric.

Wonderful reading of an 80 year old who wakes up in her younger 41 year old body, just for one day. ❤️❤️
Happy New Year everyone!
It will go by in a flash.
Make it count. 🥰
Nicole Shanahan (RFK Jr.’s former running mate) just said something that every European and American needs to hear right now:
“Progressives spend so much time turning conservatives and Christians into the enemy that we forget to think critically…
and when we finally do, we discover we actually have a TON in common.”
Then she issued a chilling warning that hits Berlin, Paris, London, and Warsaw, and Washington equally hard:
Today’s young progressives — full of genuine compassion and hope for a better world — are being manipulated in the exact same way her mother experienced during the rise of communism in China, and millions saw in Russia before totalitarianism took over.
They believed they were fighting for freedom and justice.
Instead, their empathy was weaponized to pave the way for authoritarian control.
Her exact words:
“Their empathy and compassion is being used for a fascist takeover… and they’ve been trained to see it as the exact opposite.”
This isn’t just an American problem.
From cancel culture to mass migration debates to digital censorship — the same playbook that divides people into warring tribes is running on both sides of the Atlantic.
The people aren’t the enemy.
The script that makes us hate each other is.
Watch the full clip.
If you care about real freedom — anywhere in the West — this will stop you in your tracks.
Today I turn 55.
I’m the fittest, sharpest, and happiest I’ve ever been.
If I’m an outlier, it’s not because I’m built different or discovered a secret formula. The truth is far less glamorous:
It’s a million tiny choices, compounded over decades.
Here are 55 of them:
1. Walk 15+ miles a week, even if you do other exercise. Humans are uniquely made to move slowly over long distances—it’s critical to longevity.
2. Develop a writing practice. It’s the single best way to sharpen your mind. And remember, you don’t have to be a good writer to write. Start with 10 minutes a day.
3. Swap out your toothpaste, deodorant, lotions, soap, shampoo, and other personal care products for natural versions. Here’s a rule of thumb: Don’t put anything on your skin that you couldn’t safely eat.
4. If you have a positive thought about someone, don’t keep it to yourself—share it immediately. Encouragement defies the laws of physics: When you give energy, you also receive it.
5. Wear shoes with a wide forefoot (I like Topo Athletic) and wear toe spreaders around the house (search “yoga toes” on Amazon). Spine health begins with the feet.
6. Get sunlight regularly. Moderate sun exposure (without sunscreen) is hugely important for overall health.
7. Do a 3-minute deep (“ass to grass”) squat every morning. Deep squats are often called the anti-aging exercise. It’s been said that, “It’s not that you can’t do deep squats because you’re old, it’s that you’re old because you can’t do deep squats.”
8. Explore minimalism (it’s not what you think it is).
9. Set boundaries on toxic relationships. We tend to cling to relationships past their expiration date, and it takes a bigger toll on our health than we recognize.
10. Eat real food. Not too much. Don’t eat garbage. Binge occasionally. Fast occasionally. That’s the diet.
11. Learn about FIRE. It’s a great framework for financial success.
12. Don’t take antibiotics except in emergency situations. They’re massively over-prescribed and aren’t needed in most cases. Antibiotics have done untold damage to our guts, which is where health begins. Great natural alternatives are out there.
13. Get 8 hours of quality sleep each night. To optimize sleep:
—Don’t eat after 6pm
—Get blackout shades and cover LEDs with black tape
—No screens 2 hours before bed
—Try ashwagandha (an herb) to calm the nervous system
14. Stop drinking, even in moderation. People find all sorts of ways to justify drinking, but there’s no escaping the simple fact that alcohol is a toxin and it limits your potential.
15. Travel as much as possible. Nothing expands the mind like seeing the world. And travel doesn’t have to be expensive—the best experiences happen outside of fancy resorts, when you live like a local.
16. Let go of resentment. When you forgive someone, you release the prisoner, and the prisoner isn’t them… it’s you.
17. Show up on time, every time. Poor time management limits success more than most people realize. If you struggle with punctuality, stop everything else and fix that first.
18. Spend lots of time in nature and touch the earth. Humans evolved over 300k years to live in harmony with nature, and only recently have we retreated indoors. If you don’t spend time outside, you’re fighting biology (hint: You won’t win.)
19. Stop doing dumb things. As Leo Tolstoy said, “People try to do all sorts of clever and difficult things to improve life instead of doing the simplest, easiest thing—refusing to participate in activities that make life bad.”
20. Find your happy place and (eventually) move there. Most people live where they live because... that's where they live. We are products of our environment—choose yours carefully.
21. Find a hobby and pursue mastery. You can’t have a happy life without a passionate pursuit that isn’t your vocation. Your work—even if you enjoy it—isn’t enough.
22. Avoid mainstream medicine except as a last resort. The results are in—our healthcare (or more appropriately, sick care) system is badly broken and only makes people sicker.
23. Have a mindset of abundance. There is no advantage to being a pessimist—even if you’re right, it’s a miserable way to live. In a very real way… whatever you believe, you’re right!
24. Do hard things. Choose courage over comfort. Everything you want is on the other side of fear and hard work. As Jerzy Gregorik said, “Hard choices, easy life. Easy choices, hard life.”
25. Ignore haters. Hurt people hurt people. Negative/toxic people live in a prison of their own design. Don’t join them!
26. Say no. Protect your time and energy like it’s your most precious asset… because it is.
27. Become a water snob. As an alien said on Star Trek, humans are “ugly bags of mostly water.” You are what you drink—literally! We have Mountain Valley Spring water delivered in glass 5-gallon jugs and also have whole-house water filter (Aquasana Rhino).
28. Stop drinking sodas and sugary energy drinks. After a few weeks you won’t miss them, and a few months later they’ll seem disgusting. Refined sugar causes inflammation, which is the root of most disease.
29. If you’re over 35, find a good functional/longevity medicine doctor and start tracking your hormones. Modern life is hell on the endocrine system and restoring healthy hormone levels can change your life. As we get older, we either accept a slow decline in performance or we do something about it—choose the latter!
30. Develop a morning routine and follow it faithfully. Win the morning, win the day!
31. Invest in experiences, not things. People frequently regret buying things, but rarely regret investing in great experiences (especially when shared with loved ones). Remember, there’s nothing you can buy in a mall that you’ll remember in ten years.
32. Explore spirituality. It’s arrogant and small-minded to believe there’s nothing going on in our universe that is beyond our comprehension. We know less about our universe than an ant meandering on a sidewalk understands about this planet.
33. Have a strong bias toward action—doing rather than talking. If you ask a bunch of old people about their regrets, they’ll talk about the things they *didn't* do—the shots they didn’t take—more than the things they did do (even if it went wrong). As Wayne Gretzky famously said, “You miss 100% of the shots you don’t take.” Most people don’t take enough shots.
34. Stay lean. Men in particular are obsessed with muscle mass these days, but bulk doesn’t age well. The goal is to be strong but lean. The fittest guys in their 50s and beyond aren’t meatheads, they’re lean guys who are serious about a sport.
35. Curate your inner circle carefully. Surround yourself with people you admire and who challenge you to grow. Remember, we’re the average of our 5 closest relationships.
36. Be the fittest version of yourself. Your body is your only vessel for experiencing life—so treat it as such. Fitness isn’t working out a few times a week, it’s a lifestyle. The older you get, the more time you need to devote to your health.
37. Take the time to appreciate art and beauty in all its forms.
38. Think globally, but act locally. Too many people put their energy into far-away problems they don’t understand and can’t impact, while ignoring problems right under their nose. Want to change the world? Start at home.
39. Try psychedelics. It’s one of those things everyone should do at least once, and it might be the breakthrough you’ve been looking for.
40. Limit bad habits, including unhealthy thought patterns. We all have them—practice avoidance and find substitutes. Get professional help if needed.
41. Be a lifelong learner. Your brain is just like a muscle—if you don’t feed and flex it regularly, it will atrophy.
42. Find your purpose. People with a strong sense of purpose are happier and live longer. Lack of purpose sucks energy and magnifies depression.
43. Only take advice from people who embody the traits you want to have. Talk is cheap—emulate those who have DONE it.
44. The goal is not to retire and do nothing, it’s to build a great day-to-day life that you don’t need to escape. A life of leisure is a slow death. Happiness isn’t possible without a little struggle, uncertainty, and skin in the game.
45. Have fun! Do frivolous and silly things that make you smile. As George Bernard Shaw famously said, “We don't stop playing because we grow old; we grow old because we stop playing.”
46. Whatever you want to do or achieve in life, start NOW. Don’t fall victim to “someday thinking” because someday never comes.
47. Accumulate assets—things that grow in value over time. It’s the #1 habit of rich people, and it can be done in tiny chunks. Instead of spending $100 on an impulse purchase that has no lasting value, put that money into an index fund or Bitcoin. It becomes addictive (in a good way).
48. Don’t ignore the big 3 canaries in the coal mine for health:
—Low libido (and ED)
—Frequent sinus & respiratory issues
—Depression
These usually aren’t medical conditions in themselves, they’re symptoms of an underlying problem. Find a good doc (outside of the mainstream) and figure out the root cause.
49. Have a clear vision for your future. How can you decide which direction to go if you haven’t clearly defined the destination? It sounds obvious, but 95% of people haven’t defined their “Ideal End State” in detail and in writing. (Check out my thread on this topic.)
50. Make your own decisions. We live in an era where most of what society tells us is wrong. Don’t be afraid to break from societal norms—if people say you’re crazy, it’s a sign that you’re doing something right.
51. Get hardcore about mobility exercise. As you age, it’s usually the knees, hips, and lower back that limit physical performance. 30 min a couple times a week can spare you a lifetime of pain. YouTube is a great resource.
52. Go all in on family. Get married, stay married, have kids. Burn the boats. In the end, family is all that matters.
53. Be ruthless with your time. Money comes and goes. Time only goes. Audit your calendar ruthlessly—cut the trivial, double down on the meaningful, and spend your hours like your life depends on it. (Because it does.)
54. Have a strong bias toward action. Be curious, try things, meet people—it’s how you increase your surface area for serendipity, the most powerful unseen force in our lives.
55. Reinvent yourself every decade. Over time, we slowly drift off course from our priorities, values, and true identity. Take stock and don’t be afraid to hit the reset button. Bold, calculated moves made for the right reasons almost always pay off—usually even more than you can imagine.

They killed a 31 year old father of two whose only crime was to go to university campuses and engage in good faith with people who disagreed with him. If this isn’t a wake up call then we’re never going to wake up.
Trump’s life was spared, but an innocent person lost their life today in that audience. Let’s not let this loss of life be overshadowed by the magnitude of the story.
Dear Lord, be with this family in their time of sorrow.
I have a feeling our international enemies are going to take advantage of the next few months leading up to the election as they smell the weakness. It would be in Biden's best interest to start acting like an irrationally insane madman just to scare them.
This story is remarkable, not just for the content, which is as good or better than anything we've ever published, but because of the work the reporters went through to complete it. It's a testament to what journalism can be. https://t.co/yAY3iMz3Mi
