The focus of the Lincoln Memorial is this sculpture of Abraham Lincoln, seated. Daniel Chester French studied many of Mathew Brady's photographs of Lincoln, and depicted the president as worn and pensive, gazing eastwards down the Reflecting Pool at the capital's starkest emblem of the Union, the Washington Monument. One hand is clenched, the other open. Beneath his hands, the Roman fasces, symbols of the authority of the Republic, are sculpted in relief on the seat.

The Tughra (طغراء) of Mahmud II. A tughra is a Turkish paisley-like calligraphic seal or signature used at the beginning of sultans' decrees. These colorful emblems incorporated the ruler's name and title in intricate vegetal inscriptions designed by neshanis, or court calligraphers. Parallel to the European signet, tughras often appeared on coins and stamps of the Ottoman Empire.

A TRACE image of sunspots. This image of the surface, or photosphere, of the sun from September 2002, is taken in the far ultraviolet in on a relatively quite day for solar activity, but still shows a large sunspot group visible as a bright area near the horizon. Although sunspots are relatively cool regions on the surface of the sun, the bright glowing gas flowing around the sunspots have a temperature of over one million °C (1.8 million °F). The high temperatures are thought to be related to the rapidly changing magnetic field loops that channel solar plasma.

Lichtenstein Castle is a fairy-tale castle located near Honau in the Swabian Alb, Baden-Wurttemberg, Germany. Although there have been previous castles on the site, the current castle was constructed by Duke Wilhelm of Urach in 1840 after being inspired by Wilhelm Hauff's novel Lichtenstein. The romantic Neo-Gothic design of the castle was created by the architect Carl Alexander Heideloff.

The Falkirk Wheel is a rotating boat lift connecting the Forth and Clyde Canal with the Union Canal near Falkirk in central Scotland. It consists of two diametrically opposed caissons which rotate to transfer boats between the two canals through a height of 35 metres. Thanks to Archimedes' principle, the caissons always weigh the same, whether carrying up to 600 tonnes worth of canal barges, or just water. As such, the wheel is always perfectly balanced and despite its enormous mass, rotates through 180° in less than four minutes using just a few kilowatts.
