- Did you know that I would like to know how to post youtube videos on here so you can see the video and not the link? lol
- Did you know that this whirlpool can eat everything?
There's a TED talk that mentions it would only take about 2 billions dollars to end world hunger.
If LIIW's 1/7 go hungry is right (and it sounds close enough), that's $2 each. It would end world hunger for about four hours.
I guess they expect the hungry people to invest and live off the interest...
I still don't quite get how starving people are still surviving and reproducing. I would be thinking, "Hey, I'm starving. I'm hungry all the time. This is a crappy life. I'm not bringing anyone else into this." And then it ends in a generation. I could see if there was a gigantic disaster that destroyed the ability for people to get food... so then they're starving. But there have been starving people ads out the whole time I can remember. There must be some kind of sustainable-but-starving population going on out there.

They do have kidsAnd many of their kids DIE!!!It's easy to dismiss this from the viewpoint of a middle or higher class Western lifestyleTheir kids die, they die There is no 911 to call, no doctor if they get sick, no ambulance if they get hurt When they don't have enough food, they die No shelters, no handouts, after they've eaten bugs and garbage for awhile, it all comes to an endAnd thanks to Western intervention, no birth control available to limit the number of kids they are going to have Because, horrors, that would be equivalent to abortion, and that must be far worse than millions starving to death
did you know your reflection in a mirror is the same size no matter what distance you are standing from the mirror?
No, because it isn't.
test it. stand in front of a mirror and outline your head with tape or lipstick. no matter how far away you stand the size doesn't change. the image on the surface of the mirror is half the size of the observer because a mirror is always halfway between the observer and the image that appears inside the mirror.
My mirror seems to obey the laws of optics, though I'd be interested in where you got one that doesn't.
i think you are misunderstanding something. the measurement is of YOU the observer or something that is the same distance as your eyes.
I have a small hand held mirror. Close up, my face is bigger than it. At arms length, there's space around my head. And yes, I did say "around"!
Handheld mirrors are often curved for magnification.I think the OP means a flat mirror
Hmm.Suppose instead of a mirror, we use an external observer. Suppose instead of our head we use a standard six foot human.Now put the observer at ten yards, and again at 100 yards. Or meters, depends where you live. Halfway for the ten yard observer is five yards, and half way for the second case is 50 yards.Does this imply that the five yard image and the fifty yard image are the same size?What about the size of the image on the retina?
And you are trying this with one eye open, not two?
there's a vodka with what looks like a an upside down Scriabin on the bottle?!
