Saturday assorted links
1. A new tactile alphabet, and is Braille obsolete?
2. Will neuroscience help us with sports?
3. Weak currencies don’t cause persistent trade surpluses: “Is there any field outside of macroeconomics where the so-called experts make more elementary errors in opinion pieces?”
4. Arnold Kling on the Iran deal.
5. Why can’t you default on the IMF?, except when you can. By the way, it’s the ECB who owes the IMF, ultimately, not Greece. With complications.
6. A.O. Scott on Comic-Con, one of the best pieces I have read this year.
