In this review paper I will be detailing in considerable depth my updated opinions regarding the optimal method of performing a rotary pelvic motion during the downswing. I will specifically describe in great detail the anatomy of the pelvis and pelvic girdle muscles, and the likely biomechanical actions used by many professional golfers when they rotate their pelvis during their downswing action. I suspect that many modern-day golf instructors are teaching a suboptimal pelvic motion technique and I also believe that many amateur golfers are using the wrong muscles to perform a rotary pelvic motion during their early-mid downswing. I think that those amateur golfers could significantly improve their rotary pelvic motion during the downswing if they would use the same pelvic motion biomechanics that are used by many professional golfers like Sam Snead, Ben Hogan, Jack Nicklaus, Arnold Palmer, Lew Worsham, Jordan Spieth and Jason Day and I hope that this review paper will provide those amateur golfers with a much greater insight into the optimum way of performing a rotary pelvic motion during the downswing. I have produced a 1 hour 48 minute video to supplement this review paper, and I have posted that video on you-tube. Also, note that I am an inflexible 67 year old senior golfer who lacks the ability to demonstrate the rotary pelvic motions efficiently, so always remember to listen to what I am saying if my body motions are not condordant with I am saying at any time point during the video presentation Finally, note that I previously wrote a review paper regarding the topic of pelvic motion during the downswing – The Backswing and Downswing Hip Pivot Movements:

Speedometers by Chris Woodford. Excuse me, sir, have you any idea how fast you were going? That’s the question every motorist dreads being asked by a police officer at the side of the road. If you were staring straight ahead, not looking at the dashboard, you might have only a vague idea what to say. If you were looking at the speedometer, on the other hand, you’ll know the answer exactly, possibly to within one or two kilometers or miles per hour. Have you ever stopped to think how a speedometer actually works?
In precise timekeeping, ΔT (Delta T, delta-T, deltaT, or DT) is a measure of the cumulative effect of the departure of the Earth’s rotation period from the fixed-length day of atomic time. Formally it is the time difference obtained by subtracting Universal Time (UT, defined by the Earth’s rotation) from Terrestrial Time (TT, independent of the Earth’s rotation): ΔT = TT − UT.

At first, it was primarily for single mothers who had an easy way to find themselves a new beta to provide for her and her kids. Today, classic dating sites are slowly but surely dying while sugar baby sites are on the rise. Not only has their user base grown tremendously over the past few years but this kind of relationship has been more and more pushed as normal into the mainstream media.
Even feminists found a way to support it. Thanks to the unbalanced sexual marketplace and declining public morals, being a sugar baby is a new way to monetize your body as a woman. But what are the consequences?
Q: How can the universe expand faster than the speed of light?
Posted on October 29, by The Physicist Physicist: Unlike regular angular momentum, spin has nothing to do with actual spinning. Any sane person thinking about angular momentum is thinking about rotation. However, at the atomic scale you start to find some strange, contradictory results, and intuition becomes about as useful as a pogo stick in a chess game. Anytime you take a current and run it in a loop or, equivalently, take an electrically charged object and spin it, you get a magnetic field.
This magnetic field takes the usual, bar-magnet-looking form, with a north pole and a south pole.
Amino Acid Dating Introduction. Amino acid dating has an important attribute in common with Carbon 14 dating. While most other dating mechanisms date the rock surrounding fossils, both Amino Acid and Carbon 14 dating methods, date the actual fossil itself.
History of Technology Heroes and Villains – A little light reading Here you will find a brief history of technology. Initially inspired by the development of batteries, it covers technology in general and includes some interesting little known, or long forgotten, facts as well as a few myths about the development of technology, the science behind it, the context in which it occurred and the deeds of the many personalities, eccentrics and charlatans involved.
You may find the Search Engine , the Technology Timeline or the Hall of Fame quicker if you are looking for something or somebody in particular. Scroll down and see what treasures you can discover. Background We think of a battery today as a source of portable power, but it is no exaggeration to say that the battery is one of the most important inventions in the history of mankind.
Volta’s pile was at first a technical curiosity but this new electrochemical phenomenon very quickly opened the door to new branches of both physics and chemistry and a myriad of discoveries, inventions and applications. The electronics, computers and communications industries, power engineering and much of the chemical industry of today were founded on discoveries made possible by the battery. Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations.
They did not have the benefit of cheap, off the shelf, mass produced batteries. For many years the telegraph, and later the telephone, industries were the only consumers of batteries in modest volumes and it wasn’t until the twentieth century that new applications created the demand that made the battery a commodity item.

Brakes Older Raleigh-made brakes used special cables with moulded ends on both ends of the cables, as shown. These cables are no longer available. They were supplied in different configurations for front, gent’s rear and lady’s rear applications. The cable came with the adjusting barrel. To replace the cable assembly, you would unbolt the adjusting barrel from the caliper. These cables can often be revived by dripping oil into them and working them back and forth.

This could have been discovered by accident. Humans also found a way to move heavy objects, with an invention archeologists call the sledge. Logs or sticks were placed under an object and used to drag the heavy object, like a sled and a wedge put together. Early man placed rollers beneath heavy objects so that they could be moved easily. Humans thought to use the round logs and a sledge together.
Early men began to place runners under a heavy load, which they discovered would make it easier for the load to drag. This was the invention of the sledge.

Universal time[ edit ] Universal Time is a time scale based on the Earth’s rotation , which is somewhat irregular over short periods days up to a century , thus any time based on it cannot have an accuracy better than 1 in But the principal effect is over the long term: However, there are other forces changing the rotation rate of the Earth. The most important one is believed to be a result of the melting of continental ice sheets at the end of the last glacial period.
This removed their tremendous weight, allowing the land under them to begin to rebound upward in the polar regions, which has been continuing and will continue until isostatic equilibrium is reached. This ” post-glacial rebound ” brings mass closer to the rotation axis of the Earth, which makes the Earth spin faster, according to the law of conservation of angular momentum ,[ clarification needed ]: This is indeed the average rate as observed over the past 27 centuries.

Speed networking is like speed dating for professionals. It evolved from the speed dating model of meeting a lot of people in a short amount of time. Speed networking is a structured process for facilitating introductions and conversation between people who don’t know each other. The model is often employed at events for college alumni groups , chamber of commerce groups, professional organizations, and college or corporate orientations to develop relationships among participants.
How Speed Networking Works A variety of methods can be used to structure interaction with a common thread being the rotation of participants so that each person gets the opportunity to interact with every other person attending the event. Each participant is allotted a period of time to introduce herself which will vary from 30 seconds to 5 minutes depending on the size of the group. When you RSVP for a speed networking event, you’ll be advised of how it will work, how to prepare, and what the dress code is for the program.
Have an Elevator Speech Ready Prepare a short elevator speech which summarizes key elements of your work and educational history as well as what you’re thinking about regarding your future career path. Practice articulating this information in a smooth and succinct way within the time parameters of the event. Since speed networking is a two way process, it is important to listen carefully to each of your partners to make sure you understand their situation and so you can offer advice and help, whenever possible.
Bring Business Cards Business cards are often exchanged during speed networking events, and participants who hit it off can seek further opportunities for a one-on-one exchange. This might take place at a reception after the speed networking component of an event or on another day over a cup of coffee.

Bleak outlook for Australian equities as market gravity shifts north
The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.
We are told that these methods are accurate to a few percent, and that there are many different methods.

Advertisement The ASX is typically responsive to global recoveries, such as the one happening now. But the Australian market was currently showing few signs of a synchronised upswing, the analysis noted.
Economic indicators such as strong business conditions and employment growth are being balanced by weak household sentiment and spending in Australia, providing a relatively complex local picture for global investors to digest. They will be net sellers of Australia and net buyers of China. Credit Suisse expects this to greatly benefit two Australian companies:
