Fort Carroll - Forgotten Guardian

Fort Carroll is an abandoned Army fort on an artificial island in Baltimore's harbor. Robert E. Lee designed its hexagonal structure and supervised its construction, which the U.S. Army Corps of Engineers commenced in 1848. The fort was declared defunct in 1921, having never seen combat. Sitting in the middle of the Patapsco River, it can be seen clearly from the Key Bridge (named after a witness to an event at Baltimore's more famous fort), but rarely is it seen up close. Certainly, it helps if you have a boat. [more inside]

Mathematics vs. Democracy: A Clear Winner or a Tie Game?

The Marquis de Condorcet and Admiral Jean-Charles de Borda were two men of the French Enlightenment who struggled with how to design voting systems that accurately reflected voters' preferences. Condorcet favored a method that required the winner in a multiparty election to win a series of head-to-head contests, but he also discovered that his method easily led to a paradoxes that produced no clear winners. The Borda method avoids the Condorcet paradox by requiring voters to rank choices numerically in order of preference, but this method is flawed because the withdrawal of a last-place candidate can reverse the election results. Mathematicians in the 19th century attempted to design better voting systems, including Lewis Carroll, who favored an early form of proportional representation. Economist Kenneth Arrow argued that designing a perfect voting system was futile, because his "impossibility theorem" proved that it's impossible to design a non-dictatorial voting system that fulfills five basic criteria of fairness.
