The hydraulic pin holding the tower arm in place did not retract. If that can be fixed tonight, there will be another launch attempt tomorrow at 5:30 CT.

Elon Musk reveals the single idea that explains why he keeps working despite being worth $800 billion "When I was a teenager, I had an existential crisis trying to figure out what's the meaning of life. It doesn't seem to be any meaning" "For me at least, the religious texts that I read did not seem convincing. Then I started reading the philosophers. You have to be careful of reading German philosophers as a teenager. It's definitely not going to help with your depression" "Reading Schopenhauer and Nietzsche, as a kid you're like, whoa" "Then I read Hitchhiker's Guide to the Galaxy. What Douglas Adams was saying is that we don't really know what the right questions are to ask. The real problem is trying to formulate the question. To really have the right question, you need a much bigger computer than Earth" "The universe is the answer. What is the question? Or what are the questions?" "The more we can expand the scope and scale of consciousness, the better we can understand what questions to ask about the answer that is the universe" "The more we can expand consciousness, become a multi-planet species, ultimately a multi-stellar species, we have a chance of figuring out what the hell's going on" "This is why I think we should have more humans and more digital, both biological and digital consciousness"

Starship and Super Heavy V3 moved to the pad at Starbase for final testing and preparations for launch

Attempt to use Grok Build to visualize some physics concepts for education. Prompt: "I want you to explain Navier-Stokes equations and how it relates to airfoil design. visualize this with math-manim tool"

If you wait until your 50s to get serious about cardiovascular markers, you're a decade late. Ding and colleagues recently published the most comprehensive human aging proteomics study to date in Cell. 516 samples across 13 different tissues, spanning ages in their 20s through their 70s. They tracked how the body's protein machinery changes across the lifespan. For most of your 30s and 40s, your proteome stays relatively quiet. Slow drift, no major reorganization. Then around age 50, the aging signal across the tissues studied shifts sharply. The body doesn't slowly wear out across the decades. It hits an inflection point and restructures. This pattern isn't entirely new. Lehallier et al. (2019, Nat Med) reported similar non-linear waves around ages 34, 60, and 78 in plasma proteomics. Shen et al. (2024, Nat Aging) found inflections around 44 and 60. Ding's work adds tissue resolution and confirms a major wave at 50. The most striking detail: blood vessels are among the earliest tissues to show aging signatures. Not the brain. Not the liver. The vasculature. The team identified a protein called GAS6 as a candidate driver of vascular aging. Why this matters for anyone in their 30s or 40s. Most people don't get serious about cardiovascular markers until their 50s or 60s. After a borderline cholesterol panel. After a doctor flags something. By that point, the proteome already restructured a decade earlier. You're treating the consequences. The data says the leverage window is your 40s, while change is still slow. Three vascular markers worth getting before 50: ApoB. A more accurate cardiovascular risk marker than LDL alone. Measures the actual atherogenic particle count. Blood pressure. Single largest modifiable cardiovascular risk factor. Track at home with a quality cuff. Lipoprotein(a). Largely genetic. One measurement tells you if you're carrying elevated risk for life. Ding's paper is observational. It doesn't test interventions. But the timing finding is robust. The inflection is real, it's around 50, and the vasculature crosses the threshold first. The 40s aren't too early for vascular care. They're when the data says vascular care actually matters. Ding et al., Cell, 2025 Lehallier et al., Nat Med, 2019 Shen et al., Nat Aging, 2024

The comments are so funny, thinking some $40K private school is going to make a difference. Have they considered if you're smart enough to make $10M you're probably the person who should be teaching anyway? Oh right, they didn't get $10M
