Ice ages are not random. They're timed by the Earth's orbit. Predictable wobbles, tilts, and stretches that repeat over tens of thousands of years. A Serbian mathematician figured this out while he was a prisoner of war. From a library, he did all the calculations by hand. This is how ice ages actually work.

The only book an entrepreneur needs.
Eric Jorgenson 📚 ☀️@EricJorgenson

🚨📕 THE BOOK OF ELON IS NOW LIVE!!! 🎉🚀 This is the book we WISHED @elonmusk would write… “All of Elon's most useful ideas, in his own words.” Learn directly from the world’s greatest entrepreneur, like you’re sitting across from him at dinner. It took FIVE YEARS to make this for you. Because it's built from hundreds and hundreds of Elon's public appearances. I went through 3,000,000+ words to collect the most useful and timeless ideas. The final book is ~50,000 words. Every word is USEFUL. (This is what I do. My first book, The Almanack of Naval Ravikant, is one of the top 100 most highlighted books of all time on Kindle.) Then, I spent $50,000+ on editing and design so it looks and feels beautiful. Then… > Foreword by @naval. > Visuals by @jackbutcher. > Blurb from @mrbeast. > Published by @scribemediaco. > And yes, approval on this idea from Elon himself, thanks to @samteller. I went Maximum Effort to make this an all-timer. We got 10/10 on reviews from early readers, then worked on it for ANOTHER YEAR. Why so much effort? My mission is to create One Million Musks. For a generation to lift our gaze and build, so our grandchildren live in a world beyond our wildest dreams. I’m an independent author. I don’t get an advance. I risk my own time and money to make these books. Then we give away millions of them. Digital versions are free. I believe this book can benefit every human, and if you can’t pay five bucks for it, I want to personally gift it to you. Because I know it is useful. Useful how? You may be seeking purpose, a mission worthy of your life’s effort. You may have a clear purpose and seek the tools for success. You will find both in this book. Get the benefits of Elon’s entire life of hard-won lessons in a five-hour, easy read. (I checked, it’s a 5th-grade reading level.) You’ll feel personally mentored by the greatest entrepreneur in history. Click below to buy it now on Amazon, Audible, or directly from me. Amazon: amzn.to/47avSuh Audible: lnkd.in/gi_7HrFP Me: lnkd.in/gS2xWUWH If you’re not sure it’s worth $4.99 yet, just start reading the free version. PLEASE take 6 seconds to Like, Bookmark, and Repost. Even better: send this to your friends, team, or Group Chats! I guarantee this book will improve their lives. Spread the word! Every little thing helps. Your support spreads good ideas around the world, helping people and making the future better for everyone. Thank you! Forward. Together.

Feels like we're back in space age after about 6 decades. The next one will be at least as iconic as the 1960s & the moon landing ! NASA's Artemis program drives much of the current development, aiming for a permanent Artemis Base Camp near the lunar south pole to enable extended stays eventually supporting sustained human presence (like the ISS) starting in the early 2030s! NASA will use this as a preparation for an eventual human missions to Mars !

A study in Nature Communications (March 2025) by Josias Lang-Ritter of Aalto University revealed a major flaw. Rural populations in global population datasets (WorldPop, LandScan, GHS-POP etc.) are systematically underestimated by 53-84% . Even the best datasets miss about half of the rural people based on comparisons with precise local counts from over 300+ dam/resettlement projects across 35 countries from 1975 to 2010. The gaps come from census/satellite limitations in remote areas. Official global estimates of 8.2 billion ppl are likely too low as about 43% of humanity lives rurally. Worth thinking over how many people might be invisible in the data we've been relying on. And the implications it has for aid, climate models, resource and food planning !

Almost every AI power user I know is MORE stressed and busier after using AI, not less What people thought AI would do: 10x productivity so that we can finish work earlier & relax more What it’s actually doing: 10x productivity so that we end up with 20x more things to do cos of the sheer possibilities

For 25 years, my team has been told we were wrong, by scientists, big pharma, the media, ethicists, and trolls. It hasn’t been easy Looking back, it was 100% worth it Here’s why you should believe in yourself… 🧵

Today, Ozempic, Mounjaro & other GLP-1 meds just got cheaper in India. So the big question: Should YOU start using them for weight loss or diabetes? Here’s a clear, evidence-based breakdown thread for you. (Consult your doctor, I am just a messenger)

glp-1s will decimate the fast food vendors in india because when semaglutide goes off patent next week, prices will plummet by at least 90%! this means all of a sudden, the average indian WILL be able to afford these meds and the appetite suppressant effects along with changes in taste buds is going to cause a blood bath for fast food places AND e-commerce food delivery businesses like swiggy/zomato.

It's a momentous day for healthcare in India, China & Canada today. With Novo Nordisk's patent for semaglutide officially expiring yesterday (March 20, 2026), several top Indian pharma companies have flooded the market today with generic versions, drastically slashing prices by 50% to 90% compared to innovator brands like Ozempic and Wegovy which traditionally cost between $95-$180 monthly.

First view of the 100kw AI Mini Sat with solar panels and heat radiator to scale. “And that’s just the Mini version. We expect future versions to go to the megawatt range.” — Elon The key missing ingredient is a terawatt of AI compute. Fully integrated fab with recursive improvement locally. Will explore non-traditional computing. Austin, TX. Optimus robots: 1-10 billion units/year. D3 chip optimized for space, designed to run hotter to minimize radiator mass. It will be the vast majority of the compute 100-200GW/yr on Earth. +1TW/yr in space because of power constraints on Earth.

@earthcurated This one was taken ~2018 on the Interstate 90 in Berkshire mountains Massachusetts. Aka Massachusetts Turnpike. Google Maps often secretly bypasses a section of it, rerouting drivers off the I-90 between Sturgis (South Dakota) and Billings (Montana) onto the US 212.

Milankovitch published his masterwork in 1941. It was mostly ignored. It took until the 1970s for deep-sea sediment cores and ice core data to confirm his predictions. The climate record matched his math almost perfectly. He'd spent four years in a library during a world war, calculating something nobody believed. He was right. Based on his cycles, the next ice age would naturally start in ~10,000 years. But human CO2 has likely overridden the cycle entirely. The metronome is still ticking. We just turned up the heater.

Now there's a counterintuitive key insight: Ice ages are caused by cool summers and not by cold winters. Every winter, snow falls. Every summer, most of it melts. But if summers become too cool to melt all the previous winter's snow... the leftovers survive into the next year. More snow falls on top. More sunlight is reflected back. The ice grows. Year after year, century after century, it compresses into ice sheets kilometers thick. When all three cycles align to weaken Northern summer sunlight, ice ages begin.
