    Science

    Dr. Sasho Mackenzie had a quote in the March issue of Golf magazine that I liked. Listen, there'll always be science-deniers and the belief that none of what I or other researchers do is necessary. They're going to be eroded away. There'll be fewer and fewer of these people once the community realizes that science and technology are simply about learning and understanding better ways to swing a golf club. I no longer feel bad for the instructors who fight it, because the information's out there. If they've got a theory that's different from mine, fine. I'm open-minded. I'll listen. Maybe I've made a mistake, but if they don't have an argument other than, "I believe in my method," then okay. I can't do anything else. We can't have a logical debate. I just feel bad for the golfers they're teaching. Emphasis mine. Unfortunately, another quote applies: You can't reason someone out of a position they didn't reason themselves into.
  2. https://www.missionjuno.swri.edu/news/juno_spacecraft_in_orbit_around_mighty_jupiter Just shy of 5 years the Juno spacecraft has successfully entered Jupiter's orbit. It occurred on July 4th, at 8:53 PM PDT.

  4. Our discussion in another thread about the consistency of all golfers' swings was very interesting, and enlightening I think for most of us. In the discussion, we agreed that if golf swings were essentially repeating and consistent for all golfers irrespective of skill level, but that results obviously varied significantly across skill levels, there must be some variability somewhere in the poor golf swings that isn't immediately recognizable on standard video. We used the terms "macro" and "micro" to illustrate this; we said all of our swings are consistent on the "macro" level, but that the worse you are at golf, the more inconsistent your swing is at the "micro" level. This got me thinking about whether anyone has studied this, and of course, someone has. And as you might imagine, the studies come from our friends in the UK, the home of golf....appropriately so, I think. This paper is a collaboration of scientists from Leeds University in England and University of Limerick in Ireland. It's not what you might expect from an article on the golf swing....it's highly technical and it isn't easy at first to see how it applies to how we play golf or how golf is taught, but I think it's very interesting reading. I put it here instead of the swing or instruction forums because it's really more a geek thing than a golf thing. But I think this kind of research will someday help us a great deal in showing us how to go about teaching and learning golf. The study looked at the variability from swing to swing for expert golfers (hcp </= 5), and correlated that variability with the variability of outcome of the flight of the ball. For this study, they used ball velocity as the outcome measure. The measure of variability was extremely high tech; a three dimentional motion analysis of multiple points on the body, including two on the head, and several on the upper torso and several more on the legs and feet. The study found that there was no correlation between the variability of the golfers' swings and the variability of their outcomes. In other words, even though each golfer's swing varied from swing to swing with regard to how each body part moved, the variability of these movements did not predict variability of the outcome. Stated yet another way....they weren't able to determine that consistency or lack of it among any specific body part predicts anything about the result of a shot. Read! Enjoy! Talk amongst yuh-selves. Tucker et al (2013) Is outcome variability related to movement variability in golf.pdf
  5. This will be an odd post to write, and I'm going to ask for some leeway in how you interpret it to give me the benefit of the doubt. This is not a rant, I'm not upset, and this is not aimed at anyone in particular. I, more than anyone else, am aware of my flaws and limitations, and unaware of much of what other people do, and I recognize that. I also stand by the work I've done here on TST, with my students, and with the various other things I've done over the years - training a hundred or so instructors in 5SK, writing a book and making a Lowest Score Wins DVD, the work, time, and energy I've put into traveling to work with experts in biomechanics and other hard sciences, the money I've spent getting "toys" and conducting my own research with them, and so on. Give me a little benefit of the doubt that my mood in writing this is perhaps best described as "mildly disappointed but not at all surprised." That post struck me as appropriate. It's in a thread where @Phil McGleno was responding to @Marty2019 re: Paul Wilson, how much you use your arms and wrists (and how) in the golf swing, etc. While I remain almost 100% convinced that @Marty2019 is "wrong" with his own theory about how he doesn't use his arms as more than connecting his body to the club… (while simultaneously understanding that if that's what he feels he's doing it's a completely different thing altogether)… he's not really going to a chemist and arguing with a pet theory over a chemical reaction. This is true simply because there is no universally accepted truth in golf instruction like we have in basic chemistry. @Marty2019 could cite several other "chemists" that back his theory - "chemists" with years of experience, YouTube videos, DVDs perhaps, websites of their own, and thousands of students. Because there's no rigorous testing or scientific process to determine when someone is a "golf expert," golfers have to rely mostly on perception: does the person seem like they know what they're talking about? Unfortunately, too often, that test fails, simply because it's pretty easy to fall into the trap of something that sounds logical. A charismatic instructor can make you believe a lot of things are true or beneficial when they are not. Add in a dash of golfers who secretly hope to find "the secret" or "that one tip" that will put them over the top, and you have a recipe for disaster: a golfer who will spend time, money, and energy chasing the dream of finally being able to break 80, or par, or hit the ball 270 yards, or sink every putt they look at, or whatever… What can I do about it? Not a whole lot, except to keep trying to hold myself to a high standard, and to educate as many people about the standard to which they should hold their instructor to as well. Golf is not in the age of chemistry, it's still - unfortunately - more like the days of alchemy.
  6. Media outlets - particularly those of a political nature - are filled with pieces about the environment, and there is of course a huge, emotional debate over climate. This study makes it all seem trivial. As I read it, nothing short of a return to hunter-gatherer societies, or some type of society with orders-of-magnitude less economic activity than what we have now, can save us from mass extinction. Oh, it's a few centuries into the future for sure, so we can keep playing golf. But in geologic time, we just have a few minutes left. I can't link the full text article, but if you email the author he will send you a pdf if you want to read it. http://www.pnas.org/content/112/31/9511.abstract?sid=51bb8ecc-dbd4-43fe-8c9c-638cb9b65589 http://www.resilience.org/stories/2015-08-11/the-earth-s-battery-is-running-low
