Problem: The ultimate substantive legacy of Principia Mathematica is mixed. It is generally accepted that Kurt Godel's incompleteness theorem of 1931 definitively demonstrated that for any set of axioms and inference rules proposed to encapsulate mathematics, there would in fact be some truths of mathematics which could not be deduced from them, and hence that Principia Mathematica could never achieve its aims. However, Godel could not have come to this conclusion without Whitehead and Russell's book. In this way, Principia Mathematica's legacy might be described as its key role in disproving the possibility of achieving its own stated goals. But beyond this somewhat ironic legacy, the book popularized modern mathematical logic and drew important connections between logic, epistemology, and metaphysics.
Why was Godels finding ironic?

Problem: The 2013 season resulted in much as the same the year before. Shortly before the trade deadline, the Cubs traded Matt Garza to the Texas Rangers for Mike Olt, C. J. Edwards, Neil Ramirez, and Justin Grimm. Three days later, the Cubs sent Alfonso Soriano to the New York Yankees for minor leaguer Corey Black. The mid season fire sale led to another last place finish in the NL Central, finishing with a record of 66-96. Although there was a five-game improvement in the record from the year before, Anthony Rizzo and Starlin Castro seemed to take steps backward in their development. On September 30, 2013, Theo Epstein made the decision to fire manager Dale Sveum after just two seasons at the helm of the Cubs. The regression of several young players was thought to be the main focus point, as the front office said Dale would not be judged based on wins and losses. In two seasons as skipper, Sveum finished with a record of 127-197.
How many seasons did Dale Sveum spend with the Cubs before getting fired?

Answer: two seasons

Problem: The first extant Estonian book is a bilingual German-Estonian translation of the Lutheran catechism by S. Wanradt and J. Koell dating to 1535, during the Protestant Reformation period. An Estonian grammar book to be used by priests was printed in German in 1637. The New Testament was translated into southern Estonian in 1686 (northern Estonian, 1715). The two languages were united based on northern Estonian by Anton thor Helle.
What book was not used by priests in 1637?
