  • Robotics (or more broadly mechatronics) is a super interesting field. To do the work at the mechanical/electrical interface is really hard.

    The field of industrial controls skips the hard part and just buys stuff that is pre-designed to move. Then those pre-designed pieces are made to fit and work together. It’s like complicated Legos and is honestly very fun and rewarding.

    If you want to do programming with a physical result, controls engineering is a great option. I would recommend shooting for the hard stuff (real programming - DSP, FPGA, etc) knowing you’ve got a safe fallback with industrial controls (PLC programming).
















  • Risk assessment is probability and severity. The probability can be vanishingly low, but if the severity is astoundingly high then acting like a high risk situation could be appropriate.

    Take asteroids. The last planet killer to hit us was 94million years ago. A rudimentary estimate could put the probably as 1:94mil. The severity of an asteroid impact of that magnitude is off the charts, so it is reasonable to consider it a risk and act accordingly to spend resources to search for and track asteroid trajectories.

    The severity of abduction, murder, and rape is probably pretty high for most people, so considering it a risk even with a very small probability is not unreasonable.



  • https://en.m.wikipedia.org/wiki/Aluminium_recycling

    Aluminium recycling is the process in which secondary commercial aluminium is created from scrap or other forms of end-of-life or otherwise unusable aluminium.[1] It involves re-melting the metal, which is cheaper and more energy-efficient than the production of virgin aluminium by electrolysis of alumina (Al2O3) refined from raw bauxite by use of the Bayer and Hall–Héroult processes.

    Recycling scrap aluminium requires only 5% of the energy used to make new aluminium from the raw ore.[2]


  • Cans and glass are infinitely recyclable. Recycling aluminum saves 96% of the energy of producing new.

    Paper is semi recyclable, but it degrades, so it can only go through the process a certain number of times.

    Plastic is marginally recyclable. Only about 10% of plastic that goes into a recycling bin gets recycled. It was a hoax by petro-chem to make plastic seem more sustainable than it is.


  • I’d argue the checks and balances worked, the electorate failed. Trump tried to overturn and election and the checks and balances held. That should have been political suicide. He should have not even won a school board seat after that, but the electorate failed and reinstated him. You cannot build enough checks and balances into representative government to save the electorate from repeated mistakes. The checks are there to ensure someone must show their true intents to the electorate before they make a choice.
