    “Room Temperature” Superconductor?

    Note: these results are still new and will need to be replicated and further studied by the scientific community. This whole thing may be nonsense, but I did some thinking on the impact if it’s true. Researchers from Korea University have synthesized a superconductor that works at ambient pressure and mild oven-like temperatures (like 260…

  • Endurance and Altitude for Propeller-driven Aircraft

    Lower altitude = higher endurance? At first glance this didn’t make sense to me. Air Force pilots will be the first to tell you that you don’t hug the earth en route to maximize your time on station, it is harder slogging in thicker air. At higher altitudes you have lower air pressure and colder…

  • Weaponizing the Weather

    “Intervention in atmospheric and climatic matters . . . will unfold on a scale difficult to imagine at present. . . . this will merge each nation’s affairs with those of every other, more thoroughly than the threat of a nuclear or any other war would have done.” — J. von Neumann Disclaimer: This is…

  • Playing with Matched Filters

    During my time on the red team, we continually discussed the role of matched filters in everything from GPS to fire control radars. While I’m having a blast at DARPA where I work in cyber, I wanted to review an old topic and put MATLAB’s phased array toolbox to the test. (Yes, radar friends this…
