  • 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).




  • 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.





  • This is a cool take! I don’t think I agree though. I assume we developed pattern recognition before music/language. Many animals have the ability to note attributes about plants and animals even without the ability to communicate complex ideas (ie language or oral tradition). I assume that type of pattern recognition was a good blueprint for functions like music and language, but my guess is it started from a general pattern recognition, then was retuned for music and language.

    Again, pure speculation, but there is some logic behind it!
