  • Even if the switch ‘instantly’ completed the circuit, electricity does not move along a wire at the ‘speed of light’, but only about 66% of that speed. If the light contains a filament, it has to heat up to several hundres of degrees before it’s visible. Fluorescent takes longer; even an LED does not shed light ‘instantly’. So he was wrong on multiple counts. BUT they don’t teach such details in college (except in physics classes). AFAIK,most junior high ‘science’ teachers are not all that familiar with such details.




  • Right on. The way the way population is right now, every time a chunk of mountain or glacier falls down, or a river floods, tens of thousands die or are displaced.

    In 1960 there were 2-3 billion people on the planet. Now it’s 3x as many cars, mouths to feed, homes to heat/cool.

    In Bangladesh there are over 1 million Rohingan refugees who’ve been there for TEN YEARS. They can’t work there, have no country to move to, have to live on $6-12 a month for food.
