Easy Steps to Long, Straight Shots
By Kim Jeong-kyooKorea Times Golf Columnist

To hit the long, straight drives, accurate irons and precise partial shots, it's essential to be committed to sound pre-swing basics, hard practice and dedication to the game. However, they are not all that are required to be an advanced golfer. There are a few critical in-swing keys that all great players focus on.
Try them out one by one, pick the best two or three and incorporate them into your swing. You will hit the ball better on a more consistent basis.
1. Cross the right forearm over the left through the ball.
Many tour pros cross their right forearm over the left through impact so that their left hand is below the right just after impact. They create an X-shape in their forearms during the follow-through.
Releasing the club in that fashion increases the clubhead speed through the ball, creating more distance. That also promotes solid impact as it keeps your head from moving ahead of the ball on the downswing, which avoids a faulty outside-to-in swing path. Similarly, the motion keeps your left arm from bending at impact and during the follow-through, preventing the chicken wing.
Importantly, it guarantees to stop a slice as it delivers the clubhead to the ball with its face square or slightly closed.
A similar key to preventing slice is to rotate the back of your left hand aggressively through the ball so that it points at the ground immediately after impact. Rolling your left hand in that manner leads your right arm to rotate over your left through impact, thus squaring the clubface at impact. You will produce a straight or a powerful draw.
2. Rotate hips through the ball
All great players rotate their hips toward the target through impact. That helps hit the ball farther, straighter and more accurately.
Properly controlling the speed of your hip rotation encourages your arms to stay in front of your body at impact.
Ideally, your hips need to be open about 45 degrees at impact but your goal needs to be rotating your hips completely through to the finish so that your belt buckle is pointing at the target at the completion of your swing.
Rotating your hips properly with your head still will prompt you to finish your swing with your back arched in a position resembling a reverse C-shape, but golfers with back pain need to avoid the reverse C-shaped finish as it puts unnecessary strain on the lower back.
A good way to avoid this C-shaped finish or rather to control the speed of your hip rotation is to focus on placing your right shoulder over your left foot in the follow-through with the majority of your bodyweight on the back of your left heel. That promotes proper hip rotation and powerful clubhead release, improving balance.
3. Maintain the side tilt of your spine to the right away from the target
For a proper setup it's essential to tilt your spine right away from the target and to hit the ball firmly you need to maintain the side tilt of the spine throughout the swing. That facilitates delivering the club to the ball on a path that is from inside the ball-target line, enabling you to keep your arms in front of the body at impact without a conscious effort.
Keeping the spine angle intact also helps keep your arms and body moving in synchronization during the downswing.
A good way to maintain the spine angle throughout the swing is protruding your rear end out backward at address and maintain the position during the entire swing. Sticking your rear out will cause your buttocks to position behind your heel line, causing a tight tension felt on the small of your back.
Importantly, that gets the roundness out of your spine, guaranteeing the natural curve on your lower back. A straight spine is essential to turn your body freely on the backswing and swing the club down on the proper inside path, two ingredients for solid powerful impact.
4. Maintain angle on the right wrist
Crucial to hitting the ball far and straight is to maintain the angle formed on the right wrist during the backswing late into the downswing.
Advanced golfers make sure that the clubhead stays still above their head when their hands are at waist level. That happens as they maintain the wrist hinge late into the downswing. Delaying your release leads to storing power until the last moment, thus maximizing the clubhead speed at impact.
Importantly, delaying the release prevents the coming-over-the-top problem, enabling you to hit the ball powerfully on a path that is from inside the ball-target line.

Indeed straight...

Baseball swing

2006-09-16T23:50:00.000-07:00

Try wood swing to iron. It works mysteriously.
Not sure though if the same I can do with real ball at the range or field.
Another issue would be slices, which I see in the wood swing.

Automatic weight shift

2006-09-16T20:16:00.000-07:00

1. Start addressing the ball on the left foot side

2. Weight is more than 70% on the left foot, default position.

3. During backswing, weight shifts to the rigth foot momentarily, then comes back to the left foot, the default position, "automatically".

4. There is "a bit of" body translation back during backswing to forward during downswing, helping weight shift described in 3.

5. Stance should a bit WIDE with asymmetricity due to the left leaned ball position to ease the body translation and straight impact.

c.f. During impact, weight should be on the left foot. Above tip ensures this occurs automatically.

Irons sucked
Woods so so

You are looking at your ball almost vertically.
Especially for higher number irons.

Spine almost upright
Neck and head bent forward

Spine+neck lean forward together

Oscillation, ball position, and knees

2006-09-14T08:04:00.000-07:00

1.
When addressing, you often do "stepping" between your right and left foot.
This is very good for feeling the shift of center of mass between feet.
The way you step is like "damped 1st harmonic oscillation".
At first large steps and gradually smaller steps and at the end of it, start of swing.

2.
Be aware that the optimal ball position changes depending on the situation:
i.e. the first iron swing and the same iron swing after using woods will have
different optimal ball position.
For me, it goes more than the middle to "close and square" the face the club head.
Thus optimal ball position tends to go further left side.

3.
For irons, left knee can bend quite a lot. It's natural motion induced by other body
motion. Thus, don't try to force a certain knee posture and accomodate other
body motion. Never.

Another improvement

2006-09-13T20:36:00.000-07:00

DON'T NEED TO BEND YOUR KNEES TOO CONCIOUSLY.

AIM THE BACK BOTTOM OF THE BALL.

Another KEYS

2006-09-12T21:06:00.000-07:00

1. "Fasten" your right foot and knee: you remember the twisting motion?!

2. Chin up and should be able to see your left shoulder passes and comes back.

Again stressing how hanging arms (almost) vertically is important...

2006-09-11T20:21:00.000-07:00

This determines whether ball fades or not in my current swing.
This removes unnecessary strain in my back and left arm during swing.
This enables/applies to every iron and wood

*** Important: BALL POSITION

1. 7 Iron: Middle or little toward right foot
2. 5 Iron: 1 or less ball toward left foot
3. 3 Iron: ~1.5 or 2.0 balls toward left foot
4. 1, 3, 5 Wood: ball on the left toe, chin up

Almost there??

Missing link for iron

2006-09-10T20:46:00.000-07:00

; was hanging your arms almost vertically.

Driver and putter

2006-09-08T22:41:00.000-07:00

REMEMBER CY.

Driver:
1. Stance: SHOULDER!! (appreciably narrower than iron stance)
2. Ball position: TOE, left foot
3. Address: In the middle
4. CHIN UP!! (enough shoulder rotation for backswing )
5. Never open shoulder first

Putter:
1. Stance: SHOULDER
2. Swing always stops at the left foot toe.
3. Distance depends on how far backstroke goes.
4. MAKE REFERENCE: ex. right toe to left toe stroke --> 1.5~2.0 clubs (after ~1 club, ball follows lie) --> determine the extent of back-stroke based on this
5. Putting for within 1.5 m --> right to left toe stroke is enough (not follow lie too much but go straight)

Finish

2006-09-08T16:48:00.000-07:00

Jim Furyk and Vijay Singh

Never omit "pulling arms" motion during back-swing

2006-09-07T21:25:00.000-07:00

1. Never omit "pulling arms" motion during back-swing.

2. To the top, maintain reasonable swing speed and rhythm.

3. Just a little bit of rest at the top.

4. Wack the ball with rhythm.

Natural feeling of swing (espcially driver)

2006-09-06T22:20:00.000-07:00

Arms swing first during downswing.

Never open shoulder up.

Arms swing away from the body.

Practice normal swing with feet and knees touching each other.

"Desiderata" by Max Ehrmann

Desiderata

Go placidly amid the noise and haste,
and remember what peace there may be in silence.
As far as possible without surrenderbe on good terms with all persons.
Speak your truth quietly and clearly;
and listen to others,
even the dull and the ignorant;
they too have their story.

Avoid loud and aggressive persons,
they are vexations to the spirit.
If you compare yourself with others,
you may become vain and bitter;
for always there will be greater and lesser persons than yourself.
Enjoy your achievements as well as your plans.

Keep interested in your own career, however humble;
it is a real possession in the changing fortunes of time.
Exercise caution in your business affairs;
for the world is full of trickery.
But let this not blind you to what virtue there is;
many persons strive for high ideals;
and everywhere life is full of heroism.

Be yourself.
Especially, do not feign affection.
Neither be cynical about love;
for in the face of all aridity and disenchantment
it is as perennial as the grass.

Take kindly the counsel of the years,
gracefully surrendering the things of youth.
Nurture strength of spirit to shield you in sudden misfortune.
But do not distress yourself with dark imaginings.
Many fears are born of fatigue and loneliness.
Beyond a wholesome discipline,
be gentle with yourself.

You are a child of the universe,
no less than the trees and the stars;
you have a right to be here.
And whether or not it is clear to you,
no doubt the universe is unfolding as it should.

Therefore be at peace with God,
whatever you conceive Him to be,
and whatever your labors and aspirations,
in the noisy confusion of life keep peace with your soul.

With all its sham, drudgery, and broken dreams,
it is still a beautiful world.
Be cheerful.
Strive to be happy.

Buisiness consulting

2006-02-02T07:47:00.000-08:00

There was a free dinner hosted by Boston Consulting Group Seoul Office at a center city resturant.

Information acquired was useful;
1. Basic recruiting process/time schedule
2. Qualification they want cadidates to have
3. Job functions
4. Company structure
5. Company Culture
6. Behavioral/biographical characteristics of people in the company
7. Requirement to be fulfilled for me if I were to get in the company

Meeting folks from different major was also fun;
One from law school and another from Wharton Ph.D program.

Free dinner was fine but not super great tasty. Too bad for the price.

Overall, it was interesting new experience.
I was encouraged to challenge other new experiences and situations.
I found it it fun and thrillful in some way.
But not sure, I would really go for the buisiness consulting.
We'll see.

Sleepless night

2005-12-29T23:17:00.000-08:00

Too many thoughts in the mind.
Too hard to fall asleep...

Living regularily willl be definitely one of the most impornt New Year's resolutions.
Lots of sutffs passing my mind, but let's not forget what's really important for the life.
But still not a easy thing. Always reality gets mingled with idealty.

Sleepless night.
Don't be swayed by foolish thoughts.
Whatever you think is important, it's foolish dumb thing you don't want to think now.

Money, achievement, noblty, decency, healthfulness, exercise, experiement, paper writing, hospital, family, future, bitter taste, hate, mixed bag, and God; things crossing over my mind at this moment...

Tomorrow is near around. God help us.

What I don't like

2005-12-20T18:08:00.000-08:00

Some people are sneaky. I don't like them. In fact, I don't want to work with them.
Some people use fancy nomenclatures but they don't understand what they mean. I don't like them.
Some people do both of the above. I hate them.

Picky instruments; I don't like them but have to tame and make them work.
But they are so much better than people mentioned above.

Dr. Hwang crisis

2005-12-15T05:28:00.000-08:00

What the heck is going on now....
Were all those reports and news bullshits?
What were shame if that's really true...

Finally...

2005-12-13T19:20:00.000-08:00

It seems now it's fine for him with my idea graduating sometime around next year. Glad to see such response of him finally. Now ball is on my side.

Execution and persistence. Those are what I dire to keep now for the goal.

Fab work

2005-12-08T20:41:00.000-08:00

Soooo tired after all those works in the fab.
The most sickening thing was using buffered oxide etch.
Can't sway away the feeling that I might have been exposed to harmful HF.
MSDN intructions says symptoms might appear even after 8 hrs; no immediate event is not necessarily meaning nothing. Now 8 hrs passed since I went out of the fab and nothing really happened execpt for extreme tiredness. Hoply all fine...

The current time 11:46 PM. I am wrapping up my day doing RIE (etching Si with SF6).
One thing I have to confess before really wrapping up the day. There was one thing
that all day long really bothered me... Jack - He seems not so happy with my intention to graduate next year fall. Maybe I should've hidden the idea... Was I too careless?

Well... we'll see. One Science paper would solve everything.

Job interview at Chicago

2005-12-01T23:26:00.000-08:00

Tired with two flights (each taking 2 hrs, Philly <-> Chicago) plus 2 and 1/2 hr delay. Not smart cab driver also took me to a wrong place, and it turned out that he even didn't know how to go to the destination I wanted to go. What the.... It eventually cost me invaluable 2 hr + $70.00.

Interview and result were satisfactory anyway. Heard approximate offer (salary, incentive and other benefit stuffs). Well... it was just the same as what I heard: okay level but less than my hope ($100,000 per year ?!) Gotta graduate first if I really want to go to that company at any case. Don't see that bright future + thrilling research interest in FED though...
I think I want to do research more related optoelectronics, like LED/Laser device development and the growth of related materials at present. It would be great if application of my knowledge in "nano" were available...

How to pattern nanowires?

2005-11-29T22:57:00.000-08:00

Regarding the functional/hierarchical patterning of nanowires for device applications, a few methods can be found in the literature and the most successful (?) ones are, in my opinion, solution technique from Lieber group and micro-contact printing from Rogers' group at UIUC. However, they do not seem to be viable for practical applicaions.

I envision nanowires grow from specific positions to desired directions in the future.
The key factor to be carefully considered is controlling growth rate.
Too fast supersaturation of metal catalyst would induce uncontrolled nucleation and growth of nanowires; the slower reaction, the better controlled nucleation of nanowire.
Growth kinetics (of a certain crystallographic orientation) could be controlled by adjusting reaction condition, e.g. III-V reactant ration in III-V group nitride system, which in turn would control the morphology and the growth direction of nanowire.

Still much further way to go...

2006 Accent

Scooped from a Korean website. 2006 Hyundai Accent hatchback. Probably will be available next year in the market.

Being sluggish

2005-11-28T09:56:00.000-08:00

Lots of things to do, but I can't help being lazy and laying back... It's hard to take a rest without feeling any stress. seems that I need to somehow increase the efficiency of working, so that I don't feel stressful with the same amount of work I do. Today I will do some annealing, schedule a ebeam session and send out my resume to a company.
