…2007b, and 2007c). Proofs contain errors. Han’s proof of RH (2008). Proof contains errors. These once-hopeful provers of RH are only the tip of the iceberg. But that’s not what’s really fearful about proposing a proof of RH. Check out the way that Stanford mathematician Brian Conrad layed into this nut job, for being arrogant about a purported proof! I suppose you can’t escape when duty calls. (A note on Conrad’s last sentence: he’s evidently not…

How can the law of uniform velocity provide bounds on the time it takes for a body to fall? On Monday, I’ll elaborate on that last hint. (It’s actually an interesting problem all by itself.) Later, I’ll sketch a little bit of the first answer to this challenge, which was given by Pierre de Fermat in an obscure letter to Gassendi, arou…

Rowling’s “complete works” for this royal sum. This is not dissemination of information. This is you failing the academic community. Because of your silliness, Souriau’s scholarship is not being widely shared in the way that the academic community needs. In this case,…

Obscure and Confused Ideas contains Pitt-graduate Greg Frost-Arnold’s thoughts on logic, early analytic philosophy, and the philosophy of science. The Statistical Mechanic (a.k.a. Wolfgang Beirl) has been producing some very interesting work lately on the philosophy of physics — this blog really deserves to be more widely read. The Truth Makes Me Fret is another very interesting blog that covers topi…

However, it is sufficient for us to note that in a great many cases, and in almost all common applications, initial conditions can be chosen so as to guarantee a well-posed Cauchy problem.
