  • It’s a skill that takes practice and experience more than any golden tidbit of knowledge. Food is wide and varied, what works for one thing won’t work for all.

    There are lots of general pointers, use more oil or, make sure the pan is hot first etc etc.

    One of the biggest misconceptions that people have from Teflon is food sticking and releasing and worrying about that. With Teflon, at least when it’s good and new, nothing ever sticks, at any point, ever. This is not true of anything else. Your steak will stick, for a while, and then it will let go once the protein has cooked a bit. Your pancakes will need to cook for a while before you can get them to release from the pan etc.

    Part of the skill is the implements you use and learning to release various foods from the surface. I like a wooden spatula for bulky things, but I also have a thin polyamide spatula for trickery stuff. The sharp edge on that helps a lot without damaging the pan. You can also use temperature changes to get food to release.

    Lastly, sometimes some food sticks. Don’t sweat it. It’s still edible, don’t let it ruin your meal and learn as you go.




  • Solve space and openSCAD are both great options. I have been learning solve space lately and it is great. I couldn’t learn freecad, something about the UI and workflow was just too unintuitive for me.

    I was burnt by fusion 360. Had some of “my” designs locked in the cloud when they spent 2 weeks and a dozen emails trying to “fix” my educator access. The fix they really wanted was my credit card details. I refuse to use or teach anyone to use that ecosystem now.









  • Depends if you care about names or about physics. Radio, Infrared Gamma etc are just names we give to various parts of the continuous electromagnetic spectrum. The edges of these definitions are not super well defined. Changing from RF to microwave could be defined at say about 3 GHz, but there is not some clear physical difference between a 2.9 GHz photon and a 3.1 GHz photon other than the frequency change.

    The lower limit to the frequency is I guess the inverse of the theoretical age of the universe/2. Something can’t currently be oscillating slower than that.

    There are some theories on plank length, quantisation limits, etc that might set some theoretical upper limit of photon frequency. But we don’t appear to be anywhere close to observing such things. We have seen some rather crazy short wavelength particles that we haven’t fully understood.
