The Twelve Stances of Yi-Jin-Jing (The Tendon-Altering Sutra) Part 5

第十一式打躬击鼓

接上式，右脚落地，起身向右转90度，右脚向左脚收半步，距离与肩同宽，成下蹲势。 两手抬至头侧后方，掌心按压两耳，周身放松，中、食、无名指稍屈，轻轻叩击枕骨处，两手交替进行，各叩击七次，谓之”鸣天豉”。 鸣豉后双手抱后脑，缓缓向前弯腰，头垂于裆间至最大程度，膝挺直，如打躬状。 鸣天豉时身体先向左转90度，再向右转180度，再向左转90度。 弯腰垂头时牙关咬紧，作细微自然呼吸。 重复做三遍。

11^th Stance: Bowing Down and Beating the Heavenly Drum

Continue from the last stance. Put the right foot down to the ground and stand back up. Turn 90 degrees to the right to return to facing front. Move right foot half step toward the left foot so they are at shoulder width and then squat. Raise both hands above your head and then lower them behind the head until your palms cover your ears. Relax the whole body. Slightly bend the index fingers, the middle fingers, and the ring fingers and gently tap the occipital bone with alternating hands. Tap seven times with each hand. This is called “Beating the Heavenly Drum.” After beating the drum hold the back of the head with both hands and slowly bent forward until your head cannot go any lower between your crotches. Keep the knees straight as if you are bowing down. When beating the heavenly drum, turn your body 90 degrees to the left first, next turn 180 degrees to the right and then turn 90 degrees to the left. Clench your teeth while bending forward and take small breathes naturally. Repeat three times.

第十二势：掉尾势

两腿开立，双手仰掌由胸前徐徐上举至头顶，目视掌而移，身立正直，勿挺胸凸腹；十指交叉，旋腕反掌上托，掌以向上，仰身，腰向后弯，目上视；然后上体前 屈，双臂下垂，推掌至地，昂首瞪目。呼气时，屈体下弯，脚跟稍微离地；吸气时，上身立起，脚跟着地；如此反复21次。收功：直立，两臂左右侧举，屈伸7 次。

12^th Stance: Swinging the Tail

Stand with legs spread open. Slowly raise your hands past your chest and above your head, palms facing upward. Fix your stare on your palms as they move. Keep your body upright and don’t pull back shoulders or hold out your bosom. With ten fingers crossed, rotate your wrists and then lift upward with palms facing up. Extend the upper body and bend your waist backward while looking up. Then bend your body forward with both arms stretching out on the side and touch the ground. Lift your head and open your eyes wide. When exhaling, bend forward and at the same time lift the back heels off the ground slightly. When inhaling, return upper body back to standing position and land the back heels back to the ground. Repeat 21 times. To finish the exercise, stand in upright position and raise your arms from the side. Bend and extend the arms 7 times.

Again, please see how our friendly Mr. Bruce Wen demonstrate these two stances and explain things in English. Remember, Mr. Wen's version might be slightly different from the version I translated.

This concludes the entire Twelve Stances of the Yi-Jin-Jing. The following video shows a different flavor of the Twelve Stances of Yi-Jin-Jing demonstrated by a Shaolin monk in one smooth continuous form.

第九式青龙探爪

接上式，左脚回收于右脚内侧，成立正姿势。 左臂屈肘收回于左腰间。 同时右肘微屈，吸气，上体向左扭腰转体，右手向体前探爪抓去，并吐气发出“嘘”声，此时要求腰腹放松。 右手回收，向左46度方向做第二次探爪，再收回向左90度方向做第三次探爪。 然后，头带动躯干沿逆时针方向转动一小周，右手随之书一小圆（上图）。 两眼随右爪瞭望，如寻食状。 每次探爪均发出“嘘”声。 探爪时右臂一伸一缩，身体随之转后。 然后右手收回腰间，左手以同样动作向右探爪（下图）。

9^th Stance: Green Dragon Waving Its Claws

Continue from the last stance. Retract left foot back next to the right foot in an Attention position (like in military drills). Bend the left elbow and retract left arm next to the left side of the waist. Meanwhile, bend the right elbow slightly, inhale, turn the upper torso to the left, reach forward with the right hand in a dragon claw, exhale and make a “Shu” sound. Remember to relax the waist and abdomen for this stance. Retract the right hand back and then reach out the second time 46 degrees to the left with a dragon claw. Retract again and then reach out a third time 90 degrees to the left. Next, let the head lead the torso and make a small circular movement counterclockwise. Then make a circular movement with the right hand (see upper figure). Glance following the left claw hand as if hunting for preys. Make the “Shu” sound each time when reaching out with the claw hand. Extend and retract the right arm when executing the dragon claw. Turn your body afterwards. Then retract right hand back to the waist side and reach out with the left hand in dragon claw to the right (see lower figure).

第十式卧虎捕食

接上式，左臂回收于腹前，右脚向右跨一步，同时向右转体90度，上体顺势前倾，两掌手心向右前方下扑，如卧虎捕食。 此时两掌落地，成右弓步，昂首环视（上图）。 然后以双手手指支撑全身重量，左腿屈膝成90度，左脚抬离地面，脚心朝上﹔两臂一伸一屈，身体上下起伏。 做三至五次。 而后两手离地，手心翻向上，体向左后转180度，两手掌再翻向下，再做卧虎捕食动作，唯方向相反（下图）。

10^th Stance: Crouching Tiger Hunting for Prey

Continue from the last stance. Retract the left arm back to the stomach. Take a step to the right with the right foot and at the same time turn 90 degrees to the right. Lean the upper body forward following the natural flow of the movement and pounce forward with both palms facing down like how a crouching tiger pounces on its prey. Both palms should reach the ground while the legs are in a right front stance. Raise your head and look around (see upper figure). Next use fingers from both hands to support your entire body weight. Bend the left knee to 90 degrees and lift the left foot off the ground and turn the bottom of the foot upward. One arm should be in extended position while the other one is bent. Shift your body up and down for three to five times. Then raise both hands with palms facing upward and turn your body 180 degrees to the left. Turn the palms to face downward again and execute the crouching timer pouncing on prey move, only in opposite direction (see lower figure).

In the video below you can see our friendly Mr. Bruce Wen demonstrating these two stances and explain in English. Remember, Mr. Wen's version might be slightly different from the version I translated.

10 Famous Thought Experiments That Just Boggle Your Mind Part 1

I ran into an interesting article in a forum (original in Chinese) that talked about 10 very famous thought experiments in the fields of philosophy, ethics, and psychology. Since I am getting a Doctor degree in Philosophy (hopefully), and also because I strongly believe these type of questions and experiments are very related in the research of artificial intelligence, I thought I'd share these with you together with my thoughts on the subject. Hope you enjoy!

10. The Trolley Problem

The trolley problem is a well known thought experiment in ethics, first introduced by Philippa Foot, a British philosopher. Trolley is the British term for a tram. The problem goes like this:

A trolley is running out of control down a track. In its path are five people who have been tied to the track by a mad philosopher. Fortunately, you could flip a switch, which will lead the trolley down a different track to safety. Unfortunately, there is a single person tied to that track. Should you flip the switch or do nothing?

A common answer takes the utilitarianism approach where flipping the switch becomes the obvious option because saving five lives result in a higher utility than saving just one life. But critics of the utilitarianism believe that flipping the switch constitutes a participation in the moral wrong, making one partially responsible for the death when otherwise the mad philosopher would be the sole culprit. An alternative view believes that inactivity under such a circumstance is also unethical. The bottom line: whatever you do, it is unethical. You are doomed either way.

It is reasonable to guess that your choice might vary if the single person happen to be your kid and the group of five consisted of four complete strangers plus your mother-in-law. In that case, you are simply assigning different utility values to different people (with the possibility of a negative utility). You no longer assume all people are equal. And if the group of five also included two other kids of yours, you simply assign the utility values and do the math and then make the "logical" decision (man, I am so cruel here!). This reminded me of a famous darn question people always get asked: if both your mother and your wife fall into the river and neither one knows how to swim, who should you save first? If you ever are asked this question, here's one answer you could use:

I'll jump into the river and drown myself, and we'll all go to heaven together. Now are you satisfied?

When it comes to artificial intelligence, a lot of times the choice is made based on a utility computation. Maybe the utility is computed using some fancy statistical functions. More advanced algorithms might take into consideration of probability or utility functions derived from past observations. Even more advanced algorithms might allow the agent to dynamically change or evolve the utility functions as time progresses -- a sense of learning. The agent will simply compute the utility values following whatever formulas it comes up with and then choose the option that will result with the highest utility. This is why AI agents or robots are normally considered to be very logical and at the same time very inhuman.It would be a long time before an AI agent would find itself trapped in this moral dilemma. (Remember the big computer in the movie War Games? It eventually figured out that the best winning strategy of playing the game of Tic-tac-toe was to not play the game at all).

So how would you design the AI agent or robot to be able to deal with morality, especially when you are giving it a weapon and grant it the permission to fire the weapon? Even we humans don't have clear clues in situations like in the Trolley Problem. Can we expect or require the agent or robot to do better than us? Unfortunately no one knows the right answer at the present time, we can only learn from our mistakes. Let's hope these mistakes are not disastrous and recoverable.

[Update on 8/2/2019]

Ten years have passed since I first posted this blog article. Today, many "self-driving" cars are already running on our roads (have you noticed those napping drivers in Teslas right next to you?), and there are only more to come with VCs and auto makers pouring money into this field. Now the Trolly Problem is becoming as real as it can be. When a self-driving car is faced with the dilemma of making a choice between killing the person on the left or four persons on the right, or even worse, when it needs to decide if it should sacrifice you, the passenger, in order to save four pedestrians, how would you feel about its logical choice? What if you are not the passenger, but the pedestrian, instead? Don't ask me. I don't have an answer.

Lanny's 2012 New Year Resolutions

First of all, Happy New Year to you all! Wish you all a very productive year ahead of you!!

Well, it's that time of the year again -- time to make a new list of new year resolutions. So what are you putting on your list this year? But before you start, maybe it's a good idea to pause for a minute and think how well you did with your resolutions in the past year.

One thing is for sure, the year of 2011 went by too quickly!! There were many things I wanted to finish but didn't. I am still working on my dissertation and there are still a lot left to be done. I didn't translate as much as I wanted and I also didn't post as many blogs as I had hoped. But the good thing is that I did translate some and I also did post some blogs. =) I also designed the robot I want to build and bought most of the parts. Still need to put them together and write some code to drive that thing. Let's hope that gets completed this year!

There are two very different methods of achieving success. One method is to really lower your expectations. For example, the Mars Rovers were only expected to work for 90 days, and now 6 years later, they are still working. What a great success. The other method is to set really high goals, and then even if you only accomplish a portion of what you set out to do, you would have already accomplished a lot. You'll probably find both methods applied in my new year resolutions.

Anyway, here's the resolution list for this year:

1. I will try my best to go to bed before midnight every day.
Maybe not getting enough sleep every day resulted in low performance and low efficiency. I'll make sure I get 7 hours of sleep each day this year! I also need more sleep because I'll be exercising more this year and I need the sleep to rejuvenate. (Method 2)

2. I will graduate before the world ends.
It has already been 5 years since I started grad school. Time is running out since my advisor's funding, my personal funding, and the world (according to the Mayan calendar) will all end soon. So I am DETERMINED to get my PhD before the world ends!! (Method 1)

3. I still hope I can post two blogs each day.
I actually started many drafts. The key is to complete them and publish! (Method 2)

4. I still plan to translate one page each day.
I actually translated quite a bit last year. Just didn't post them all because I wanted to mix robot related posts with translation related posts. I'll still try to stick to this plan this year! (Method 2)

It's 23 minutes past midnight already. Doh!! I better go to bed now! Wish you all have a great New Year Resolutions List and with you all stick to it!!

The Twelve Stances of Yi-Jin-Jing (The Tendon-Altering Sutra) Part 4

The Twelve Stances of Yi-Jin-Jing (The Tendon-Altering Sutra) Part 3

第七式九鬼拔马刀

接上式，两臂分开成侧平举，手心向上。 然后右臂屈肘，右手至头后，腰略弯，头略左摆，食指中指第一关节夹住左耳垂，食指微提，中指微下压，并轻轻向右牵拉。 同时左肘弯曲，左手背贴背部上移于两肩胛之间，尽力上抬，手指向上，并向左转体；微屈膝，低头看右脚背。 而后身体慢慢恢复原势， ​​头左转向后看（左图）。 定式后约静立半分钟。 反方向再仿一次（右图）。

7^th Stance: Nine Ghosts Drawing the Saber

Continue from the last stance. Open your arms and move to the side at should height with the palms facing up. Then bend the right arm and reach your right hand behind your head. Bend your waist slightly and lean your head to the left slightly. Use the first joint of the index finger and the middle finger to grip the left earlobe. Lift gently with the index finger while pushing down gently with the middle finger and pull gently to the right. At the same time bend the left elbow and place the back of your left hand upward so it is between the two shoulders. Raise your left hand as high as possible. Point the fingers upward and turn your body left. Bend knees slightly and look down at the top of the right foot. Then slowly return body to the original position. Turn your head to the left and look behind your shoulder (see left figure). After completing the stance stand still for about half a minute. Then perform and stance in opposite direction once (see right figure).

第八式三盘落地

接上式，左脚向左跨一步，两脚尖外撇。 两臂侧平举，掌心向下。 而后两腿弯曲成骑马蹲裆势，同时两掌下按，与膝齐平。 然后两臂外旋，两手翻为仰掌，两腿同时缓缓伸直站立，两臂随之慢慢上抬成侧平举。 下按时呼气，意念两掌心，如按浮木﹔上抬时吸气，仿佛两掌心放有重物。 反覆做三至五次。

8^th Stance: Three Bases Dropping to the Ground

Continue from the last stance. Take a step left with the left foot and point the feet outward. Hold your arms out flat at the side of the body at shoulder height with palms facing down. Then squat down into a horse stance and pushing downward with both palms at the same time until they are at knee height. Then rotate both arms outward and turn both palms to face up. Slowly straighten both legs to stand up at the same time and naturally raise both arms so they are flat at the side of the body. Exhale when pushing down and set your mind on the center of the two palms as if you were pushing down floating logs in water. Inhale when raising the palms as if there were heavy objects inside the two palms. Repeat three to five times.

Again our friendly Mr. Bruce Wen happily demonstrates the two stances for you and explains what each  stance is good for. If he is right, then it is recommended that you perform these two stances at a location where a convenient restroom is nearby. Remember, Mr. Wen's version might be slightly different from the version I translated.

Picture of the Day:

 I wanted to check out Google's new 3D trip planner so I searched for driving directions from Orem, UT to China. It's really interesting that Google Map suggested "Kayak across the Pacific Ocean", and it only estimated 14 days and 5 hours for this feat! I figured that I might have a slight chance of accomplishing that if I can fully master the 12 stances of Tendon-Altering Sutra! LOL!
