A few months ago I wrote a piece about living in a world of limits. The laws of physics (especially the laws of conservation of matter & energy and the laws of thermodynamics) dictate the ability to produce goods and services. The ecosystems in which we live can only absorb so much waste and generate [...]

However, since the first law of thermodynamics (also [...]

They think it is something they “can’t do” or “don’t get.” They may say they do not have a scientific brain. I can also tell you that these are entirely untrue. Real world, personally accessible examples, instead [...]
