The Peregrine Falcon, the swiftest of all birds of prey, is one of the most widely distributed species of birds, nesting on every continent except Antarctica. The world’s largest urban population of nesting Peregrine Falcons is in New York City.
The display in this hall was conceived by the Museum’s great ornithologist Frank M. Chapman. Under Chapman, the Museum’s bird collection grew to one of the greatest in the world. It holds over 95 percent of all known species of birds, or about 9,100 different kinds.

Check out the best of Princeton’s Art of Science exhibit now at @nysci. http://ow.ly/zBwYw
The Art of Science exhibition explores the interplay between science and art. Both of these disciplines involve the pursuit of those moments of discovery when what is perceived suddenly becomes more than the sum of its parts. Each piece in this exhibition is, in its own way, a record of such a moment.
Such astounding patience and skill must be needed to make these!
Mudskipper is a fish which spend more time on land than in water. In fact, a mudskipper will drown if it’s never able to reach the water’s surface! Like other fish, mudskippers breathe through gills, but in addition they absorb oxygen through their skin and the linings of their mouths and throats. They are able to move over land by using their pectoral fins to pull themselves forward, or they perform a series of skips or jumps. Pokemon “Mudkip” is based on this fish.
Fold a piece of paper in half 103 times, and its wider than the observable universe.
this is due to exponential growth; the increase in previous thickness is doubled each time you fold the piece of paper again. physically you could probably only fold a piece of paper about 7 - 8 times on your own.
Given a paper large enough—and enough energy—you can fold it as many times as you want. If you fold it 103 times, the thickness of your paper will be larger than the observable Universe; 93 billion light-years distance.
How can a 0.0039-inch-thick paper get to be as thick as the Universe?
The answer is simple: Exponential growth. The average paper thickness in 1/10th of a millimeter (0.0039 inches.) If you perfectly fold the paper in half, you will double its thickness.
Folding the paper in half a third time will get you about the thickness of a nail.
Seven folds will be about the thickness of a notebook of 128 pages.
10 folds and the paper will be about the width of a hand.
23 folds will get you to one kilometer—3,280 feet.
30 folds will get you to space. Your paper will be now 100 kilometers high.
Keep folding it. 42 folds will get you to the Moon. With 51 you will burn in the Sun.
Now fast forward to 81 folds and your paper will be 127,786 light-years, almost as thick as the Andromeda Galaxy, estimated at 141,000 light-years across.
90 folds will make your paper 130.8 million light-years across, bigger than the Virgo Supercluster, estimated at 110 million light-years. The Virgo Supercluster contains the Local Galactic Group—with Andromeda and our own Milky Way—and about 100 other galaxy groups.
And finally, at 103 folds, you will get outside of the observable Universe, which is estimated at 93 billion light-years in diameters.
A More Ancient Origin of Animal-Built Reefs
The discovery of an approximately 548-million-year-old reef in Namibia, made of the world’s earliest known skeletal animals, suggests that these aquatic organisms built reefs before the Cambrian explosion (currently dated to have begun around 540 million years ago). Until now, the oldest reefs on record made of such metazoans had been dated to about 530 million years of age. The researchers’ findings not only imply that metazoans had been building reefs millions of years before the Cambrian explosion, but also that the evolutionary pressures that led to hard parts on and connecting animals, such as skeletons and reefs, were present millions of years prior to that great speciation event as well.
