- Did you know that 1/7 of our fellow human beings are starving?

[lostinidlewonder]

- Did you know that this whirlpool can eat everything?

- Did you know that I want a piano like this? I could just play until I fall asleep. Just need a toilet system, shower and fridge and I'd be set.

There's a TED talk that mentions it would only take about 2 billions dollars to end world hunger.  I think that was the number.  And if the US just printed out 2 billion dollars more, the effect on the economy would be minimal, but it would feed everyone.


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.

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...

Think about it this way, the starving people are humans just like you and me. They have exactly the same emotions, feelings of love and joy, sadness and despair. They know they have a hard life but many of them are born into it and don't know anything else, they just know life is a huge struggle. It is very sad. We throw away food in the Western world where others are starving, this world is a real selfish place I reckon.

So, your $2 billion one off is actually $200 billion per annum. 

[Bob]

That's what I get for watching it while practicing. 

Someone can donate 2 billion.  I can donate 0 twice.  I'm that generous.   Problem solved.  What's next?



*Bob curses himself for not charging interest on that donation.*  Oh well.  At least I can write it off on my taxes.

They do have kids

And many of their kids DIE!!!

It's easy to dismiss this from the viewpoint of a middle or higher class Western lifestyle

Their 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 end

And 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

Actually whatever birth control is used in the starving areas of the world is usually a western intervention. Starving people have traditionally (even in the Western world) had plenty of kids BECAUSE the kids die so often. To have some of the kids survive to adulthood is their best security for old age.

- Did you know that this 3 year old is a real piano genius!!!

This incredible piano prodigy is only three years old. His unbelievable talent amazingly comes natural to him as he is blind and has never had a piano lesson. When Branko Dvorecky started playing, he shocked his parents with his renditions of Bach, Wagner, and Tchaikovsky. He is a "true little Mozart" according to the small village he resides in, just outside the Slovakia capital.

His tiny glissandos and poking out notes are amazing, he create his own technique to play, just amazing to witness this raw genius at early stage. I remember reading about this in Liszt as a little child pretending to play its so great to actually witness an example.

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.

[cwjalex]

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"!

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?

Handheld mirrors are often curved for magnification.
I think the OP means a flat mirror

the problem with your experiment is the assumption that a mirror behaves the same way an external observer would and that a reflection is the same visual information that an external observer would perceive in its place.  

If you are standing 2 meters in front of a mirror think of your reflection occurring not on the mirror but 2 meters behind it.  When looking at your reflection, light from the bottom and top of the mirror converges at your eye which forms a triangle.  the light bounces off the mirror on an angle and forms another triangle "behind" the mirror, meaning it forms a triangle in the 2 meters that are hypothetically behind the mirror.  these two triangles are always similar and 1/2 the size.  this is why no matter what distance you are standing from the mirror your reflected image will always be half your real size.  So if you want a mirror so that you will be able to see your entire body it has to be at least half your height.

And you are trying this with one eye open, not two?

I'm seeing the same size image (measured in the plane of the mirror) with the mirror held close up or at arms length I.e. My face always fills the mirror

[timothy42b]

Huh.

I keep a mirror on the music stand, it's a 12x12 inch piece of mirror tile.

I just put a piece of duct tape at my chin and at my hairline, sitting at the stand.

Then backed up the distance of 10 nine inch floor tiles. 

My chin and hairline fit between the duct tape about the same as up close.

[j_menz]

And you are trying this with one eye open, not two?

Two of course, which is what makes the difference.

Did you know there is a possessed piano-mirror being sold to little girls? I came upon this I think at alibaba express.and could not figure out why the image if the toy disturbed me me so much.
