An animated image showing the territorial evolution of Canada, that is, the dates when each province and territory were created. Since it was formed, Canada's external borders have changed six times, and it has grown from four provinces to ten provinces and three territories. It has only lost territory in the small border dispute with the Dominion of Newfoundland over Labrador, which joined Canada some time later. Image credit: Golbez

A path of shelled pecans makes its way through a host of unshelled ones. Pecans can be eaten fresh or used in cooking, particularly in sweet desserts, such as the pecan pie, a traditional southern U.S. recipe. Pecans are also a major ingredient in praline candy. The U.S. produces between 80% and 95% of the world's pecans, with an annual crop of 150–200 million kg (300–400 million pounds). Photo credit: Scott Bauer, ARS

Vernal Fall is a 317 ft (97 m) tall waterfall on the Merced River just downstream of Nevada Fall in Yosemite National Park, California, United States. It is accessible via the Mist Trail, which climbs close enough to the fall so that hikers must travel through the fall's mist. The waterfall runs all year long, although by the end of summer, it is substantially reduced in volume and can split into multiple strands, rather than a single curtain, of water.

This animation shows a classic example of homeomorphism: a coffee mug and a torus are topologically the same. Roughly speaking, a topological space is a geometric object and the homeomorphism is a continuous stretching and bending of the object into a new shape. The traditional joke is that topologists can't tell the coffee cup from which they are drinking from the donut they are eating, since a sufficiently pliable donut could be reshaped to the form of a coffee cup by creating a dimple and progressively enlarging it, while shrinking the hole into a handle.

This watercolor painting shows Cleveland Tower on the campus of Princeton University in Princeton, New Jersey as seen from just outside Procter Hall at the Old Graduate College in the noon autumn sun. The tower was built in 1913 as a memorial to former United States President Grover Cleveland, who also served as a university trustee. One of the largest carillons in the world, the class of 1892 bells, was installed in 1927. The Chapel Music program plays the bells Sunday afternoons during each semester, except during exam periods.
