The Truth About Wireless Charging
I agree. It explains the inefficiency (for now) of inductive charging that most people don't realize, and that at the current technology, the more it grows, the more burden it will have on the current grids.
Not really, no.
It simply reveals that there is a hidden cost to wireless charging that most people are unaware of.
The Amazon’s Boiling River Kills Anything That Enters
I'm really disappointed that this short video didn't explain why the water is so hot. Not even a hint at an explanation.
Guess I'll have to watch the TED Talk now.

Gordon Ramsay Blindly Guides Amateur Cook to Make Crab Cakes
That was great. The guy was so bad. I consider myself a pretty good cook, but I'm not even sure I could keep up with Gordon at that pace. I'd watch more of those style videos.

Sixty Symbols: Find out how the Drinking Bird works.
When I was in the 10th grade (1989), I was in a high school science class, and the professor had a drinking bird. He offered some form of extra credit if we could explain how it worked. I quickly went out and bought my own drinking bird, studied it, and had no freaking clue. So I pulled out some encyclopedias (remember those? yes kids, we used to have books of information), did some reading at the library, and 3 months later figured it had to have something to do with Boyle's Law.

I proposed my weakly formed solution completely missing out on the thermodynamics part, and never did get that extra credit.
If only I had google: Heat will not naturally flow from a body of lower temperature to one of higher. It will however, flow in the other direction. So what does all this have to do with our classic drinking bird? The answer: plenty. Couple this law of thermodynamics with Boyle’s law stating the inversely proportional relationship of temperature and pressure relating to volume and you can begin to understand how this magical little bird can seemingly bob up and down forever.
