Swimming Diary

Progress:
2008-12-02
OK. my swimming lesson this semester is over this week. I had a great time in the pool. I swam one hour every workday for the whole semester. This semester was stressful and I got some precious relief in the water.

I am preparing for the finals. Here is a link to swimming jargon: http://www.ccbswordfish.org/?p=swimming_vocab

Today I picked up sidestroke. I can do well on the left side, but usually leaped backward too much on the right side.

2008-11-14
I did not swim as much as before because the course work is heavy; Additionally, we switch to winter time now, as a result it is already dark when PED pool opens. I cannot see clearly.

I swam one hour this noon. I have mastered some basic skills; now I need to focus on balance and endurance.

Four full freestyle laps! Hurry!


2008-10-22
A remarkable progress: I somehow learned to breathe in freestyle, though it seemed awkward, un-orchestrated, and lack of rhythm. I was really excited when I suddenly found myself swimming across half lap.

Also I began to practice breaststroke.

Keep swimming! Floating Rock!

The amazing beauty of dolphin kicking: just like a fish

"A rock got such a good score!"
Thank you, William!
I should be practitioner, but not be satisfied with being a theorist

2008-10-14
It was an busy and depressing week last week because of midterms and homeworks. I didn't swim as often as before.

Now I am preparing for the swimming course midterm. Here are some notes:
1. History of Swimming
Founder of Red Cross swimming program: Wilbert E. Longfellow
Dominant swimming stroke used in Europe in the 16th century: breaststroke

2. Survival Swimming

H.E.L.P
Short for Heat Escape Lessening Posture.

1. Keep your legs together
2. Press both arms against your upper body
3. Keep your head out of the water

This position protects core area of the body from rapid heat loss.

Disrobing

Disrobe yourself of your shoes, socks, pants, belt, shirt, hats, etc. Inflate trousers for shirts as a floating device.

Riptides
Riptides, or rip currents, are long, narrow bands of water that quickly pull any objects in them away from shore and out to sea. They are dangerous but are relatively easy to escape if you stay calm. Do not struggle against the current. Most riptide deaths are not caused by the tides themselves. People often become exhausted struggling against the current, and cannot make it back to shore. Do not swim toward shore. You will be fighting the current, and you will lose. Swim parallel to shore, across the current. Generally speaking, a riptide is less than 100 ft. wide, so swimming beyond it should not be too difficult.If you cannot swim out of the riptide, float on your back and allow the riptide to take you away from shore until you are beyond the pull of the current. Rip currents generally subside 50 to 100 yards from shore.Once the riptide subsides, swim parallel to shore and then back to shore.

Boating Safety&Equipment
emergency signal
navigation aids: compass, GPS,
life jacket
navigation lights
communication equipment: radio, cellphone, flares
first aid kit
alternative power: paddles, oares
protective clothing: enough warm clothing

Sculling
Sliding the hands back and forth through the water creates a force perpendicular to the direction of the movement. This action is know as sculling. In chest-deep water, put your hands out in front of you with your fingers straight and close together. Turn your palms out and sweep your hands and forearms out to the side beneath the surface, then turn your palms in and sweep back to the center. If you scull continuously, you'll be tracing an elongated figure eight. Sculling is used extensively in back float.

Alternate breathing
Breathing every third stroke, you alternate breathing on opposite sides

Hypoxic Breathing
Breath control swimming such as underwater swimming or breathing every fifth or seventh stroke in Front crawl.

negative split

Swimming a Negative Split means that the second half of the distance is swum at a faster pace than the first half. For example, the following set:

1x 600: Negative Split

asks you to swim the second 300 yards at a faster pace and time than the first 300 yards. The idea is to control your pace at the beginning of the swim so that you have the energy necessary to swim faster at the end of the swim.

flutter kick
In swimming (either front crawl or backstroke), the legs are extended straight out in line with the body and then moved up and down, the one leg kicking downwards as the other leg moves up again. The legs are separated to not enhance wingtip vortices. The toes point in the direction of motion to mimic a hydrofoil. The knees are slightly bent to adjust the angle of attack.

Now I can finish a complete lap by backstroke, but made little progress in freestyle. The main obstacle is breathe. I gradually learn to lean my head to one side to take a breathe, but when my head gets into the water again, my nose feels very uncomfortable. So I have to grab the curb to take another breathe. This makes me a little bit of frustrated.

But I must say I really enjoy swimming. I go to the pool every workday. My muscle is becoming more powerful and I forget all worries and unhappiness in water. Sometimes I go to the deep water area, take a deep breathe and then immerse myself completely in the water. I hope to learn to how to thread the water soon.

2008-09-22
able to do 12-laps of kicking in the 25-yard pool without much difficulty.
able to swim freestyle across the lap with two or three stops
tried to do backstroke and can do few yards. The key point is to lean your head back and to straighten your body

But still don't learn how to breathe in freestyle. If you do, you can say you are able to swim now. Pay attention to the following points: 1) exhale all air out through the nose when you need to breathe . 2) rotate your head to the right side when right arm stroke back. 3) keep kicking and keep balance; 4) inhale quickly and deeply with the mouse

Also you need to learn to threading water so that you will be able to practice in deep water.

Keep the good work!

"Good Boy"

Here is my car, a Honda Accord of the year 2000. I bought this car about two months ago and gradually began to enjoy this big toy.

Many people are concerned my safety. Especially Laoyifu, who is an experienced driver, called me specially to teach me how to drive safely. His teachings includes: don't drive when you can't calm down; pay your full attention when driving; don't drive with a slippers on; and practice more before driving in freeway . I should feel guilty in regards to the last piece of advice because I mistakenly drove to the freeway on the very first day. I felt a little bit of scared at first; but fortunately there was a heavy traffic at that time as a result the speed was not that fast. I managed to leave the freeway few minutes later. Now I feel more comfortable when driving, both local and freeway, after two months' practice . I would like to thank all people who care about me. As far as now I am all right.

I have driven it to several places around Los Angeles, such as Santa Monica, Getty Center, Six Flags, Chinatown and Huntington Beach. It makes my world even bigger. I love it, good boy!

Live As You'll Die Today

Dream as if you'll live forever, live as if you'll die today.
- James Dean

Goodbye to Randy Pausch!

It was a coincidence, but it became more meaningful if I linked those two things together.

Yesterday, I first came to know the quotation in the beginning of this post:"Dream as if you'll live forever; live as if you'll die today". At the time I was wondering in Target aimlessly. I just bought a car and drove myself to this super market. It made me feel excited and powerful to control this big toy. But on the other hand, I had a strong feeling I should do something more meaningful. The first year of my PhD life seemed so flat. There was nothing noticeable and I am not sure what I should do in the future. Then I went by the picture & frame section, a poster with a white-black portrait of a serious man attracted my eyes: there were a line saying "Dream as if you'll live forever; live as if you'll die today" and the man was James Dean.

This morning I heard of the death of Randy Pausch in New York Times: Randy Pausch, 47, Dies; His ‘Last Lecture’ Inspired Many to Live With Wonder. I expected this result when I first heard of Randy Pausch: miracles seldom happens in real life. Randy was a virtual reality pioneer, a computer scientists and a professor at CMU. He was diagnosed with pancreatic cancer in Aug. 2006; then he gave a series of lectures called "The Last Lecture" in the year of 2007, which inspired many people thanks to the internet. His most memorable lecture was about his childhood dreams and how he achieved them. If he had ever heard of James' words, he must have a better understanding of it.

It's Cherry Picking Time

It is cherry picking time in Calif. The most popular place near L.A. that has lots of cherry orchards.

Leona Valley (Website http://www.cherriesupic.com/ ) There is a report about this orchards in L.A. Daily News

CHERRY PICKING TIME: It's the season to load up on fresh cherries. For a fun family outing, head to the cherry orchards in the Leona Valley from June 6 through the end of the month.

Although more than two dozen orchards allow consumers to pick their own fruit, times and days vary. Most places provide all the equipment you'll need, including buckets, bags and containers.

Prices likely will average about $2 a pound if you pick your own (a few orchards also sell picked cherries). Take cash since some growers don't take credit cards. Ask if you can taste-test varieties to find the cherry you like the best.

If you go, make the trip worthwhile and pick plenty as the cherries will last two to three weeks in the refrigerator and are easily frozen whole with stems attached for a snack long after the season is over.

To get to the Leona Valley from the San Fernando Valley, take the Antelope Valley Freeway (14) north and exit at Palmdale Boulevard. Go left (west) 10 miles on Palmdale Boulevard to 90th Street and look for the cherry orchard signs. For more information, call the Leona Valley Cherry Growers Association hotline at (661) 266-7118.

The annual cherry parade starts at 10 a.m. June 14 on 90th Street west at Leona Avenue and goes north to Elizabeth Lake Road where it proceeds east. Plan to arrive early in the morning, before the roads close.

There is link to the relatively newly updated information about Leona Valley http://www.chowhound.com/topics/528281

The second place is Beaumont Valley http://www.bcvparks.com/ This place seems to charge a higher fee and is not as popular as Leona Valley.

USC Safety Chart

Exactly Speaking, the title should be USC unsafety chart.

The following map shows the distribution of criminal activities around USC area. The data is based on DPS crime alerts since Aug. 16, 2007. From the map we can see four hot spots and one noticeable line. The four spots are W 37th St. & Vermont, Orchard & Jefferson, W 30th St. & McClintock, W. 27th St. & Hoover. The most dangerous line is Hoover St. from USC gate 4 to Adam Blvd.

These hot spots may be explained by the criminals' behavior. They often linger around certain spots. Once they find a right target, they attack and flee. The above spots are hubs from USC campus to students' residence, so it is easy for them to find a target there. And They can easily escape in main streets by car. It's rare that they wait around your residence or break into your residence because its risk is too high for them. So, it matters most on the way from the campus to your residence, and less where you live.

I will update this map when new incident occur (I hope not). You can bookmark this map with this url .

Body Worlds: Our Bodies and Respect for Life

Configuration of the Arteries of the Head and Brain

On Friday afternoon, I went to California Science Center to see the Body Worlds exhibition. The single fact that the work on display are real human corpse make this exhibition the most special one. Before I continue, I would like to introduce the plastination technique. Basically, more than 50% percent weight of our body are water and lipid. Soon after one is dead, anatomist injects a kind of chemicals into the body, which replace the water and lipid. After this treatment, the chemicals polymerizes and solidifies, thus keeping the shape and microscopic structure of the body. It doesn't decay any more even exposed to air. Dr. Gunther von Hagens invented this technique in 1970s. It was initially used for anatomy teaching, and obviously it's scientifically good.

And then Dr. Hagens explores this controversial art form. He makes the bodies posing different postures as they are alive. So, there are runners, warriors, dancers, torchbearers, horse riders, etc. But their muscle and bones are naked. You can also see nerves, arteries and veins. You see with your own eyes the internal structure of human body. But they have not find a ideal way to keep the texture and shape of skin. When you face these plastinationed bodies, they look like sculptures at first glance. But they are real human corpses. That's why this exhibition impressive.

That's also why they have an emotional impact on the audiences. Actually similar exhibitions are not allowed some cities. Though my education in biology tells that human body can in fact be reduced to basic elements, such as carbons and nitrogens, I felt strongly that they are humans, who were alive like me no long ago. This feeling made me tired; I quickly finished this supposedly 3-hour tour in two hours.

I am not religions; I don't believe in the next life. What I am concerned is how to show our respect for life. In most culture, after one man is dead and his/her body is buried to ground; we believe they can return to the nature in this way. I ask myself whether do you like to be plastination-ed or buried or burned after you die. Well, it will be interesting to let my body perpetuate than to let the body decay in the earth or burned to ashes, it hurts me that my body will be peeled, cut and displayed. So, I haven't made up my mind.
