  • 🚀 Today is the 100-year anniversary of the first liquid-fueled rocket launch

    Like the Wright Brothers, Robert Goddard’s flight changed rocketry forever, pioneering today’s mainstay, liquid-fueled SpaceX rockets. I have some artifacts from his 1926 flight (see comments below). But first, I am pointing to a scale model of Nell — Goddard’s 10’ tall rocket powered by gasoline and liquid oxygen. It went just 41’ up in… Read More

  • THINK Apple

    On April 1, Apple turns 50. As an Apple alum, I bleed 6 colors with pride. And I just got this framed display for my office… with the poster Jobs had in his… and his Apple 1 ribbon cable too.

  • Marvell at the Mojo for AI Optical Interconnect

    By using a grid of micro-LEDs instead of lasers, Mojo delivers 100x more bandwidth/channel and lower energy/bit. Mojo’s fiber has thousands of physically discrete channels for massively multiplexed bandwidth + redundancy for reliability in orbital data centers. Today, Marvell announced their long-term partnership with Mojo to develop a new class of optical interconnect solutions for… Read More

  • Introducing ZaiNar — novel PNT in software

    ZaiNar emerges today from 9 years of stealth. The company has developed a totally novel technology that tracks the location of anything that emits a radio signal (phones, drones, vehicles, IoT devices, anything with cellular or WiFi). No new hardware needed, and you get sub-meter accuracy for location and sub-nanosecond for timing sync. As AI… Read More

  • Heavy Lifting — the Book of CFS just arrived

    The cover (below) shows a top down slice of the SPARC fusion plant, with a ring of 18 D-shaped toroidal magnets, each strong enough to levitate an aircraft carrier. Embedded in the center of the cover is a slice of their superconducting VIPER cable that makes the magnets. CFS VIPER: "The magnet can handle strong… Read More

  • Centivax’s First Universal Vaccine

    Just finished a watershed board meeting at Centivax. CEO Jake Glanville is holding the first vial of universal vaccine, which just started clinical trials. In the long arc of human history, pathogens have killed the majority of humans that ever lived — over 50 Billion dead. Nothing else comes close. What has been the challenge… Read More

  • Centivax and the Universal Flu Vaccine

    Remember the variants? And vaccines that keep changing and don’t work so well? It’s not just COVID and coronaviruses, but flu, malaria, HIV and herpes/shingles too. This happens because the pathogen is constantly mutating most of its surface coat proteins to evade our immune system — it keeps looking different. But there is an invariant… Read More

    Some preserve stunning crystal chambers. When cut and polished, many fossils reveal beautiful quartz or calcite crystals filling the buoyancy chambers, turning them into natural works of art, like this sculpture of Schloenbacchia variosis Cretaceous Atlas Mountains, Khenifra Province, Morocco
