This was my biggest Aha Moment about 15 years ago. Overlap is the least utilized tool. It also allowed me to embrace things I hated. I’m a huge Berkshire investor but I have never followed Munger and Warren as “All Knowing”. They are wise but many of those followers totally missed out on the rise of Gold and Bitcoin. That has often been what saves a portfolio or adds Alpha. Here’s a tool anyone can use to see how diversified you are. It shocks people when they find out $QQQ and $VOO are 52% similar by weight. Pick one as you Base. Use this and put two of your holdings in. etfrc.com/funds/overlap.php

One thing about #Byzantine, later modified #Ottoman builds, that attracts me is use of geometric fractals. The domes and spheres resembling mitosis, a living architecture. These are dynamic and alive, not merely static planetary configurations as original purpose. With the passing of time they attain new meaning as science advances. Associations are no less coherent by anachronism, nor deviation from intended purpose. Selection of my designs: #Architecture #Domes

For the first time, scientists have mapped the complete brain and central nervous system of an adult male fruit fly — a key model organism in science. 🪰 Working alongside HHMI Janelia Research Campus and the scientific community, @GoogleResearch scientists and researchers used AI to combine millions of 2D images into 3D neural shapes, reconstructing a record-breaking 166,000+ neurons. This foundational map of the adult male fruit fly brain can help accelerate our understanding of the brain, and is a major milestone in neuroscience.

Natural selection’s trial-and-error process allows improvement without anyone understanding or guiding it. The same can apply to how we learn. There are at least three kinds of learning that foster evolution: memory-based learning (storing the information that comes in through one’s conscious mind so that we can recall it later); subconscious learning (the knowledge we take away from our experiences that never enters our conscious minds, though it affects our decision making); and “learning” that occurs without thinking at all, such as the changes in DNA that encode a species’ adaptations. I used to think that memory-based, conscious learning was the most powerful, but I’ve since come to understand that it produces less rapid progress than experimentation and adaptation. #principleoftheday

When my mom was diagnosed with brain cancer and everything she had to go through when I was in medical school, it solidified me wanting to become a neurosurgeon. And even further, it gave me the experience base that I would use for the rest of my career when talking with patients and their families and loved ones about end of life care. And for anyone reading this who has lost a parent when they were younger, I promise you it gets better and you can accomplish great things. Keep going. #cancer

Here is the link to the @guardian piece from David theguardian.com/commentisfre…

This from my friend, Stanford's David Relman, on Covid origins is worth your time. David helped write federal biosecurity policy and is one of the most thoughtful, even-handed experts in the country. David says: Rand Paul is right — NIH helped fund risky work in Wuhan that spliced bat virus fragments together like a game of chance, under weak safety rules. Tony Fauci is right too — that published work doesn't look like a plausible Covid precursor. Relman says what's needed now: — Everyone claiming certainty should back off and show some humility — A real, transparent, international investigation — Scientists accept guardrails on risky research; political leaders commit to honest public debate We're doing none of it.
