A SAT Attack on the Erdos Discrepancy Conjecture

Computers are providing solutions to math problems that we can't check - "A computer has solved the longstanding Erdős discrepancy problem! Trouble is, we have no idea what it's talking about — because the solution, which is as long as all of Wikipedia's pages combined, is far too voluminous for us puny humans to confirm."

Can Logic Be Rationally Revised?

Here is a video of the philosopher Graham Priest giving a talk at the 2012 Conference on Paradox and Logical Revision. He addresses three questions. Can logic be revised? If so, can it be revised rationally? If so, how? [more inside]

"a certain... moral flexibility would be the only way to describe it"

Our Inconsistent Ethical Instincts
We like to believe that the principled side of the equation is rooted in deep, reasoned conviction. But a growing wealth of research shows that those values often prove to be finicky, inconsistent intuitions, swayed by ethically irrelevant factors. What you say now you might disagree with in five minutes. And such wavering has implications for both public policy and our personal lives.

G.H. Hardy reviews Principia Mathematica

"Perhaps twenty or thirty people in England may be expected to read this book." G.H. Hardy's review of Whitehead and Russell's Principia Mathematica, published in the Times Literary Supplement 100 years ago last week. "The time has passed when a philosopher can afford to be ignorant of mathematics, and a little perseverance will be well rewarded. It will be something to learn how many of the spectres that have haunted philosophers modern mathematics has finally laid to rest."

Kill Math

Bret Victor on WorryDream The power to understand and predict the quantities of the world should not be restricted to those with a freakish knack for manipulating abstract symbols. When most people speak of Math, what they have in mind is more its mechanism than its essence. This "Math" consists of assigning meaning to a set of symbols, blindly shuffling around these symbols according to arcane rules, and then interpreting a meaning from the shuffled result. The process is not unlike casting lots.

    My name is Modus Tollens, and I help you spot cheaters.

    Subjects don't need formal logic training. They don't need math or philosophy. Fewer than 10 percent of the participants got it right when Peter Cathcart Wason performed his 1966 study, the Wason Selection Task. But according to an essay by Bruce Schneier referencing the work of evolutionary psychologists Leda Cosmides and John Tooby, that number improves, by 65 to 80 percent "...when the rule has to do with cheating and privilege."

    Youtube logician explains why God must exist

    Apparently there's at least a 51% chance of God's existence. It starts out 50/50, like with pets. You have, say, either a dog or a cat. It's a 50/50 chance that it's one or the other, just like it's 50/50 that there's a God or not. Well, we exist. You exist. The earth exists. That nudges it up to 51%. If I understand this youtube gentleman. Hilarious exercise in smug delivery of ironclad logic.
