Some old notes and links

VMWare's Fusion may top even Parallels and Bootcamp as a way to run Windows apps on your Mac.

After downloading the first iPhone software update, I've found the iPhone to be generally more stable. Mobile Safari was crashing a lot just before the update. Now? Not as much.

Why are U.S. health care costs so high relative to the rest of the world? Perhaps because American doctors make so much more than their international peers and because of the way they are paid--by the procedure. I'm not sure the right answer is to put doctors on a salary. If the services American doctors provide are superior or more specialized, it may be worth the money. Arnold Kling blames a different issue for soaring healthcare costs, arguing that what we have in the U.S. is more health care insulation than insurance.

Baseball Prospectus posted an interview with Dr. Alan Nathan, physics professor and also chairman of the Science and Baseball committee of SABR. In response to a question about counterintuitive baseball truths as related to physics, he offered three, the last running counter to a baseball axiom:

One example is that the grip the batter has on the bat does not play a role in the ball-bat collision. That is, a batter could just as well let go of the bat an instant before contact, and it would not make a bit of difference to what happens to the ball. Most people tend to be very skeptical of this conclusion, since they believe a batter "muscles" the ball when it is in contact with the bat. But, that is not what happens, as shown not only "theoretically" but also experimentally.

Another example has to do with the ability of the batter to track the incoming pitch. In fact, it is really impossible to do so. So, just like my previous example, the batter could just as well close his eyes when the ball is halfway to home plate and it won’t affect the outcome of the swing.

A final example: Can a batter get to first base quicker by running through the base or in a head-first slide? Most people believe the former. I believe the latter. The essential physics is that by sliding with outstretched arms, the batter reaches the bag before his center of gravity reaches it, whereas those two times more or less coincide when running through the bag.
