Actually, all of you are wrong.

The Planet Earth is accurately described as an "oblate spheroid" and is neither round nor flat.

In common use, "round" is an alternative to "flat". Then it is either round of flat, by definition.

A circle is round, a ball is spherical.

I wonder what it is in 11 dimensions?

I thought we were up to 16  dimensions?

I thought it was 11 dimensions too - 4 'normal everyday' spacetime and rest curled up and invisible to us ;)

Yes, that is one of the later models based on string theory and Brane theory of the universe.
From Wikipedia:
One such theory is the 11-dimensional M-theory, which requires spacetime to have eleven dimensions, as opposed to the usual three spatial dimensions and the fourth dimension of time. The original string theories from the 1980s describe special cases of M-theory where the eleventh dimension is a very small circle or a line, and if these formulations are considered as fundamental, then string theory requires ten dimensions. But the theory also describes universes like ours, with four observable spacetime dimensions, as well as universes with up to 10 flat space dimensions, and also cases where the position in some of the dimensions is described by a complex number rather than a real number. The notion of spacetime dimension is not fixed in string theory: it is best thought of as different in different circumstances.

That's right...turn to the side and look back at the camera...perfect...
I once asked this ole country boy how they cook wild turkey, he responded..."Ya cut off the head, dip in boiling water to get rid of the feathers, cook it at 350 for about 4 hours or so, grind it up and feed it to the dogs...then go buy a Butterball"



Beautiful photo....I love Butterball turkeys.

Absolutely fantastic!

Some older images from a safari to Kenya and Tanzania in 2007. Best holiday in my life!

Stunning work! Really beautiful shots. Great demonstration of the trusty old 100-400mm lens, too!

+1...Vossie, I echo what everyone else just said. Makes me wish I was there. :)

Great shots everyone and a well deserved front page to you Edward.

November is not exactly the most inspirational time of the year where I live, but went for a walk this morning. Taking picture of flowing water is in my view quite difficult. Either you use a very fast shutter speed to freeze the water or you allow the water to smooth out, with a slower shutter speed. But if you let it smooth too much, then there is no life left. So I tried to balance that.

So cool :) Great job! 8)

I have about 10,000 geese in the bay behind the house! They are LOUD!!!

The second shot is a 7 picture panorama and shows about 5 percent of the total flock....
WOW! ... even the 5% looks like a lot ... that must be LOUD! ... nice pic.

Ear plugs, anyone? ;D
