February 19th 1855– First weather map presented at the French Academy of Sciences
Starting in the middle portion of the 19th century, weather charts as we know them today were used to track storm systems.
The catalyst of the movement was a devastating storm that took out a whole French fleet at the battle of Balaklava during the Crimean War. Urbain Le Verrier, a mathematician specializing in celestial mechanics, showed a chronological map of the storm and how it could have been predicted and avoided by the fleet. This was presented at the French Academy of Sciences and the study of meteorology as its known today took off.

February 24th 1803– Marbury v. Madison
After the tumultuous election of 1800, southern Democratic-Republican Thomas Jefferson took office on March 4, 1801. Between the election and inauguration, Congress passed the Judiciary Act of 1801 establishing ten new district courts, expanding the amount of circuit courts from three to six, and adding additional judges to each circuit, “giving the President the authority to appoint Federal judges and justices of the peace. The act also reduced the number of Supreme Court justices from six to five, effective upon the next vacancy in the Court.”¹ When Thomas Jefferson became president, he sent a petition to the Supreme Court by William Marbury who had been appointed Justice of the Peace by outgoing president John Adams, but whose commission was not delivered. The case forms the basis for the exercise of judicial review in the United States under Article III of the Constitution. The petition was denied and the Jefferson administration had to honor the appointments of the previous president.
