    Not too much to add from what others have mentioned but this looks like a good (low cost wide fov) photon bucket with low complexity (important for reducing stray/scattered light).…

    Turns out folks are solving PDEs in excel: https://sie.scholasticahq.com/article/4654-spreadsheet-imple... (i knew about FFTs and special functions , but this looks fun/interesting…

    In calibrating satellites getting folks like you to go out with sensors on the ground to send back well vetted data is an expensive and limiting factor. Much cheaper (and often pre…

    Independent thinking like that could never be encouraged or rewarded in a place designed to produce just smart enough replacement labor. Hell, equivalent stunts in places like univ…

    That's cool to see, I remember in high school the ROTC came to track practice to get people to come out for orienteering meets. Turned out to be a fun/useful experience.

    I'm guessing you're in in automotive or aerospace based off the engine piece. I agree, but I would presume a day long meeting leading up to a wind-tunnel test for example would hav…

    Yep, a lot of places allow for 80hrs/2wks of "training". Crazy how popular those Agile/SAFE/AWS/Azure/etc. conferences are in a destination location, meanwhile engineers asking to …

    Several people from my high school went to Deep Springs. They were all incredibly bright, high potential students but definitely wanted "different". The ones I knew went on to UChi…

    Weightlifting is interesting, "most" elites have really good technique (tempo, maintaining angles throughout the pull, bottom position, lockout, etc.) indicating some level of mast…

    Control theory doesn't come up much in what I do but as a practitioner are Root Locus ever utilized? I've been unpleasantly surprised to see that exact positive feedback instance e…

    Not sure what the exact context the blog refers to (they are a scientist turned software engineer?, their field is data/software intensive and see this as an improvement area?). Ou…

    Sounds like a good project to me (we did this for a couple of labs in an undergraduate [sophomore maybe junior year] control systems class). The "inverted pendulum" problem and its…

    I think these engineering marvels whose FWHM (sorry I'm a bit rusty on what the right parameter for light gathering ability in this application) will be leaps ahead of current inst…

    Yeah this article should be more forthright in describing meta-materials/left handed media. This media is highly dispersive and described by changes in constituent properties (perm…

    It may not be that "only SMEs can work" but that "SMEs don't have 5 tickets this sprint but 3 high level deliveries over the next quarter" thus they are allowed work uninterrupted …
