Oh Dolley! Washington is Burning!
To say that the British are bitter over this little war with America is an understatement. President Madison has lifted the embargo on British goods, but the British don't care. They have blockaded the East Coast so that American exports are down 90% from their pre-war numbers and imports are down 75%. The British won't risk damage from the shore batteries of major ports, so they are pummeling smaller ports into rubble. On August 18th they bottle up American gun boats near the mouth of the Patuxent River (pay-TUX-ent), and make their way over land to Washington DC. It is a punishing march in the 100 degree heat of summer. The troops are dropping like flies. They march through the night to make up for lost time. The American forces have had weeks to prepare, but they fail in their most important task. They have not burned the bridges. President Madison almost blunders into the British troops as they come over the Bladensburg Bridge. Meanwhile, Washington residents are leaving in a panic. The First Lady, Dolley Madison, has the presence of mind to save priceless historical treasures including that famous portrait of George Washington. The British advance under a flag of truce, but there is no one left in Washington to negotiate with, so they set fire to the city. Washington D.C. is burning.   
The Sun, the Universe and Everything
It may not seem like much, but without this discovery, one could not measure the Universe. Joseph von Fraunhofer has invented the spectroscope. This device allows him to view the spectrum of various substances when they are made hot enough to give off light. He notices a bright line within the spectrum of one substance. Then he uses his spectroscope to view the light from the Sun and discovers 574 darkened lines. (There are actually millions of these lines, but hey. He's just getting started.) He wonders if there is a correspondence between the bright line of his burning substances and the darkened lines in the Sun's spectrum. As a matter of fact, there is. When a particular substance is heated to the point of incandescence, the light it gives off has a distinctive signature. Combinations of substances will give off a more complicated signature but they can be untangled to the point where one can determine what substances made that particular light. One can determine the chemical makeup of a light across the room, or from the Sun, or from the light of a star in the next galaxy.

- Francis Scott Key publishes the Star-Spangled Banner. Actually it is a poem entitled, "The Defense of Fort McHenry". It is about what he saw when he was held prisoner on a British ship as it attacked the fort. The poem will become the lyrics of America's National Anthem.

Campbell and without sanction from his superiors or the government of the United States, they also destroyed private houses and other property, prompting British commanders to demand reprisals in other theatres of the war. To some degree, the burning of Washington by the British later in the year was influenced by the American actions at Port Dover.”
- Joseph von Fraunhofer - Wikipedia (2016). Retrieved on 13 May 2016. “Thus in 1814, Fraunhofer invented the spectroscope. In the course of his experiments he discovered the bright fixed line which appears in the orange color of the spectrum when it is produced by the light of fire. This line enabled him afterward to determine the absolute power of refraction in different substances. Experiments to ascertain whether the solar spectrum contained the same bright line in the orange as that produced by the light of fire led him to the discovery of 574 dark fixed lines in the solar spectrum; millions of such fixed absorption lines are now known.”
