    How stable is the entrainment effect they plan to use in their engines under high winds, rain, changes in atmospheric pressure, etc? Accelerating air by creating a low pressure reg…

    I wonder if this is connected to the Russian military buildup on the Ukrainian border.

    Haven't the Ukrainians diverted important rivers upstream on Crimea? Undoing that could be the concession Putin is hoping for.

    Quite the opposite: such complicated games are an outlet for creativity and cleverness that's stifled by our repetitive, heavily automated society. Most people don't get to make a …

    Nuclear definitely should be paired with energy sources like wind and photovoltaics. These sources are aren't consistent, so you need something to balance the load at night or when…

    Three Mile Island and Chernobyl loom very large in the imaginations of the boomers and gen x, respectively. Nuclear plant meltdowns are world news on the few occasions they've happ…

    Hmm, so it might be out of reach for me. I have a PhD in pure math, and no experience as a software engineer. I've coded for research, but never for production.

    Thanks, that clarified it. Do you know how people typically get into that role?

    How extensive a code portfolio would someone need for you to consider them? How much experience would they need? I got my PhD about a year ago and have been retraining myself to be…

    If the image classifier it's training has learned that mailboxes and parking meters are the same thing, I wonder if there's any way to fix that without starting over! Now I'm wonde…

    The relatively low energy density means it won't be replacing li-ion batteries in vehicles any time soon. Where I could see this technology shining is in low-power consumer electro…

    Aren't there lots of NP problems that have this property?

    At the very least the proof of work ought to compute something useful.

    Given that carriers are increasingly boxed out from shore by anti-ship missiles and drones are a lot smaller than crewed aircraft, I wonder if this design concept is due for a revi…
