Depending on where you are, a thumbs up could just be a sign of approval. But in some countries, this refers to an action in the nether regions, and is meant as an offense. Visitors should note that to add insult to injury, the thumb can be jerked upwards.

...[T]he co-poly strings in use today -- which spread through the pro game only over the last decade or so -- generate more spin than ever. They do so because they're more slippery than prior string designs. Because the strings easily slide across one another, they can slip back and then snap back to position -- all while they're grabbing the ball -- to create more spin.

Hsieh/Minton OpEd: Durbin's Dietary Paternalism

Off-topic: The September 13, 2011 edition of HumanEvents.com has just published an OpEd co-authored by myself and Michelle Minton of the Competitive Enterprise Institute, "Durbin's Bill Is Dietary Paternalism".

The proposed new regulations would require many dietary supplement manufacturers to submit proofs of safety to the FDA before they could be marketed -- including many that are already freely available in drugstores and supermarkets without a prescription. This would raise the prices for many supplements and force others off the shelves entirely.

On a personal level, I am taking some of these supplements (in consultation with physician colleagues) to help with my hip fracture healing. So anything that would restrict my ability to purchase such supplements to promote my health greatly alarms me.

Many thanks to my co-author Michelle Minton and her colleagues at CEI for her excellent work and for facilitating the publication of this piece!

Physics bleg: A friend-of-a-friend is interested in receiving feedback from physicists about a pre-print of an article he has written on quantum mechanics, "Surely You Must All be Joking: An Outsider's Critique of Quantum Physics".

The author is a non-physicist at the University of Colorado. If you're willing to respond, please send your comments directly to him at: "randy.oreilly" "at" "colorado.edu" or via this link. (Please do not send your feedback to me, Paul.)

Here is the abstract:
A critique of the state of current quantum theory in physics is presented, based on a perspective outside the normal physics training. From this perspective, the acceptance of quantum nonlocality seems unwarranted, and the fundamental assumptions that give rise to it in the first place seem questionable, based on the current status of the quantum theory of light. The relevant data can instead be accounted for using physically motivated local models, based on detailed properties of the experimental setups. The semiclassical approach, particularly in the form of the fully coupled Maxwell-Dirac equations with a pure wave ontology, seems to provide a satisfying, local, paradox-free physical model of the quantum world, that appears consistent with known phenomena. It is unclear why this approach is not pursued more vigorously in the field, given its clear potential to resolve all the conundrums that have perplexed generations of physicists.
Thanks!

Open Letter to Apple: My iPad and My Hip Fracture

[Update 9/4/2011: Welcome, Instapundit readers!]

Dear Apple:

I've been a happy iPad2 owner since March 2011, but I never fully appreciated its value until I recently broke my hip in a bad fall and required subsequent hospitalization.

I am a physician, so I had already been using my iPad for my work, reading PDFs of medical articles, communicating with my colleagues via e-mail, etc. But when I broke my hip in an accident a few days ago, the iPad became my lifeline to the outside world:

Because I had my iPad with me at the time of the accident, I was able to immediately notify my friends and family of what had happened once I arrived in the ER.

In the ER, the iPad also helped keep my spirits up as I checked e-mail, followed my friends on Twitter and Facebook, and followed the regular world news. When my orthopedic surgeon presented my treatment options to me, he also e-mailed me some relevant medical literature in the form of PDF files which I could digest at my own pace on the iPad. And of course, I was also able to perform Google searches on my various surgery options, the complication rates, postoperative care requirements, etc.

Because of the specific nature of my fracture, I had to choose between two treatment options, each with its own pros and cons. I found it enormously helpful to be able to gather the relevant medical information literally "at my fingertips". Because of the iPad, I was able to more quickly make an informed treatment decision that I was comfortable with.

I did briefly leave my iPad with my wife during the surgery itself, but she gave it back to me immediately after the surgery. Other than that, it did not leave my side while in the hospital.

While in the hospital after my surgery, I used the iPad to read eBooks, check my e-mail, surf the internet, and keep up my regular blogging. It was a real morale booster to be able to continue as much of my regular online routine as possible, despite my impaired physical condition.

My wife also had her own iPad with her while I was hospitalized, which allowed her to update our friends and family in real time on my condition, as well as keep her occupied while I was asleep or in surgery.

And now that I'm at home recovering, my iPad is still at my side!

For someone such as myself with limited physical mobility, the iPad2 with its light weight and long battery life was perfect. A laptop computer simply would not have worked while in the hospital. The iPad was literally an emotional, medical, and physical lifeline for me during a difficult time in my life.

I know Apple has been in the news lately because of Steve Jobs' decision to step down as CEO. I just wanted to take this opportunity to publicly thank Mr. Jobs and Apple for creating such a wonderful, life-enhancing product.

In your advertisements, Apple has touted the iPad as "magical" and "revolutionary". To that, I would add the term "life-saver".
