Book Review : Outliers by Malcolm Gladwell


Malcolm Gladwell's Outliers, has always been highly recommended by a close friend. Her conversations around this book circled around the 10000 hour rule and how it makes sense for a Ballet dancer to invest in effort to practice one's craft.  As a result, I have been intrigued by this book for quite some time now.  When I finally got the chance to read it, I gleaned important lessons for life regardless of what your career or vocation is:

1.) Outliers are born at the right time

Mr Gladwell mentions the importance of being born with respect to a certain cut off date for a certain sport or undertaking. While observing Hockey players in Canada, he noticed that those who excelled where born a few weeks immediately after the cutoff date for tryouts. If you have a bunch of 9 year olds, closer to 10 would be at a physical and experiential advantage.  Their slight edge is noticed by coaches so they are given the extra classes and training because of perceived talent when in fact it was just a matter of age.  The perception becomes a self-fulfilling prophecy.    I guess I will have to consider it when planning entries to competitions, etc.

2.) The 10000 hour rule

The book attributed the success of the Beatles to spending more than 10000 hours playing.  They regularly crossed the English channel to play in Hamburg, Germany for 8 hour straight gigs.  At the end of the period they  were excellent.   Also cited was the experience of Bill Gates who as fortunate enough to access a time share computer and just kept working at it many hours a day until he became very good at it.  Excellence comes with a price, we should clock it 10000 hours to be great in something.


3.) IQ is not equal to success

A comparison is made between Chris Langam,  considered the smartest man in America, and J. Robert Oppenheimer, the director of the Manhattan project.  Despite being the man with the highest IQ in America, Chris Langam does not have high academic degrees nor does he have a high paying job. He is working class and lives in a farm.  J. Robert Oppenheimer was appointed head of the World Changing  Manhattan project  ( aka Build the Atomic Bomb) despite his being junior and being  a Theoretical Physics rather than an Experimentalist or Engineer.  The difference is that the latter had the benefit of being guided and supported by his upper class parents who  exposed him to formal and informal learning opportunities giving him the social skills to work with people.  Chris didn't have that because he was abandoned by his father and grew up in rural America.

4. ) Ethnicity and meaningful work 

 A discussion on the plight of Jewish immigrant is in this book, stating how they were willing to work long, inhuman hours with the vision of improving their lives.  They did not shy away from difficult work other people dismissed as menial. This ethic eventually led to the Jewish domination of law and business in the US.  Specific examples were given on how the American Jews mastered hostile takeover law practice.  By the time takeovers became common place, Jewish partnerships we practically on top of the law system. I guess the lesson here is that opportunities come to those who are not picky.


5. ) On Culture and Plane Crashes 

The book mentions the importance of recognizing cultural legacy and how it can affect the way you work.  It goes on to state how cultural legacy played an important factor in the 1997 crash of Korean Air flight 801 in Guam and  the 1990 crash of Avianca flight 057 in Long Island.  Mr Gladwell then narrates how, Korean Air changed into an airline at par with the World's safety standards.  This was accomplished by developing a new culture which started with the mandatory speaking of English in the cockpit.  It broke the cultural bias and allowed all crew members to function the without hierarchical problems of their culture.

6. ) The importance of rice 

The culture from the rice cultivating regions of the world invokes the idea of harvest being proportional to the amount and quality of work you put in.  The nature of the rice crop, leave farmers very little idle time as opposed to other cereal cultivating cultures.  The complexity of the crop also forces farmers to be innovative to ensure they make most of the harvest.  It also brings about a governance structure where the landlords only claim a fixed rent thus rewarding farmers of the excess.  I guess this is why we Filipinos are ma-diskarte in many aspects good or bad.

In summary, Outliers succeed because they were given opportunities and grab these to advance the status of their families. This book is really an inspiration to me.

Physics Problems Help - Density Problem Solutions 2

It's Physics day once again so below is my latest installment for solved problems from the 8th ed of Physics by Halliday, Resnick and Walker.

Problem 5 - We are tasked to find the molar Volume, atomic Volume, estimate of atom to atom distance for both Fe and U.



Problem 6 - In this problem,  we are tasked to get the radius of a sphere that is 5 times the mass of another sphere of given radius.



Problem 7 - this is about getting the Atomic mass of an He, Fe and Pb to be expressed in grams and atomic mass units.


Enjoy!

Ballet Steps for the Young Dancer : Battement Tendu


 One of the first things a young ballet dancer learns is the Battement Tendu.  This step is defined as the stretching of the whole leg from the hip socket to the tip of the toe. Specifically, a dancer is to  required stretch 4 things to properly execute a Tendu: 1.) the instep  2.) the top arch of the foot 3.) the toes and 4.) the back of the knee.  By directing the dancer to push the arches out as much as they can, they also stretch the toes and back of the knee as consequence.



   To prepare the young dancer for the Tendu, she is first taught how to flex and point her feet while seated on the floor.  To emphasize the desired result of elongating the leg, we call the pointed foot "good toes" and the flexed foot "bad toes".  This trains them to push the arches out and stretch their toes.  To ensure the stretching of the instep, dancers are instructed to put their little toes on the floor.  This exercise is usually done with the legs together in front and the feet in a letter V. In Graham Modern Dance, this exercise is also taught a la seconde ( legs straddled on the sides)  but may be difficult for young dancers as this variation requires  good control of the pelvis.  As an alternative, we do Cambres (torso reaches ) towards side extended legs while the feet are pointed with little toes on the floor. Training for Tendus to the back is accomplished by backward leg raises with heel together in rest position.

The first barre exercises for Tendus are done from first position.  Tendus are done  de cote (towards the sides) to give the dancer the feel of turn out before moving on to devant (front) and derriere (back). The movement of the tendu is initiated by the pushing of the arch of the feet out whilst pulling the knee back, pushing the heel  and keeping the toes on the floor as far as possible, As the toes reach their limit, they are pulled to fully point the foot up to the tip of the toes.

As the dancer advances, she is trained to do more complicated Tendus at the barre to develop stability for the combinations at the center of the class.

Math Problem Help( Algebra) - Operations involving signed numbers from College Algebra by William Hart

I first learned Algebra using the classic textbook by William Hart.  It didn't make a lot of sense then since I was more fascinated with the concepts of Physical science rather than abstract mathematics. I wasn't patient enough then to do exercises.  It was only when I started working on Calculus that I developed the discipline of going though each exercise.  I am however grateful for this book, my high school Algebra teacher and my tutor for developing the basic mathematical skills I would need later on in life.

Today we tackle Exercise 1 from Hart's College Algebra.  This covers very basic concepts of operations involving signed integers so solutions will be simple.  Nevertheless, I hope this will be helpful to the mathematical novice.

Have fun!

Exercise 1

Basic rules
- Odd number of negative factors , product is negative
-Even number of negative factors, product is positive
- For division, negatives cancel if they are both on the numerator and the denominator.
-For Absolute values, just ignore the sign and write the number.

Compute each product:

1. 8x (-3) = -24
2.(-2)(5) = -10
3. 7 x 0 = 0
4. 6x(-3)=-18
5. -(-5) = 5
6. +(-3) = -3
7. +(-1) = -1
8. -(+8) = - 8
 9. (-9)(-5) = 45
10. (+5)(-7)= -35
11. (-4)(+3) = -12
12. (-133)x0 = 0
13. (-7)(-4)(6) = 168
14. 4(-2)(-7)(-3) = -168
15. 3(5)(2)(-4) = -120
16. -4(-5)(6)(-3) = -360
17 (-5)(-3)(0)(-4) = 0
18. 5(-2)7(-3)(-4) = -840
19. (-5)(-3)(-4)(-2) = 120
20. (-1)(-1)(-1)(-1) = 1
21.(-1)(-1)(-1)(-1)(-1) = -1 
22. -1.57(-2.31) = 3.6267
23. -3.2(-4.7) = 15.04
24. 3(-1.42)(2.5) = 10.65

State the absolute value of the number

25. 17 = 17
26. -46 =46
27. -33 = 33
28. - 3/4 = 3/4
29. -1.48 = 1.48

Read the symbol and specify its value

30. | 7 | = 7
31. | -36 | = 36
32. | -9 | = 9
33. | -5/3 | = 5/3
34. | -1.3 | = 1.3

35. Find the product of -2,-5 and -2.3 = -23
36. Find the product of 5.3, -4 and 2 = - 42.4
37. Compute 4abc if a = -3, b = -4 and c = -2.
       4abc = -96
38. Compute 3xyz if x = -2, y = 10 and z = 5.3
       3xyz = -318 
39. Compute 2abxy if a = - 3, b = 4, x = - 3, and y = 5 
     2abxy = 360 

Find the negative of each number

40. -3 = 3
41. 6 = -6
42. -2/3 = 2/3
43. -8 = 8
44. 16.7 = -16.7
45. 0 = 0

Express the quotient as a positive or negative integer or a fraction

46. +16/+8 = +2
47. -16/8 = -2
48. 15/-3 = -5
49. -48/12 = - 4
50. -42/-6 = - 7
51. -36/-18 = +2
52. -28/7 =-4
53. +39/-3 = -13
54. -14/-10 = 7/5
55. +12/-36 = -1/3
56.-16/28 = -8/14
57. 0/-39 = 0

How to Improvise : Mirroring Exercise

Albert Einstein once defined Insanity as doing the same things over and over again but expecting different results.  The reality is that in our daily lives, insanity seems to be the norm. Whether its Business or at Home we find ourselves doing the same things over and over again, following the same line of thinking that got us into the problem in the first place.  It is a challenge for everyone to go off tangent and approach a situation for a different angle.

As a Physicist and Engineer, I had to face similar situations that would have led to dead end scenarios.  I am thankful for my Ballet training, having equipped me with a set of mental tools to develop my creativity. I had an easier time thinking of crazy ideas because of creative experiences I've had in the past. 

A pivotal moment in my dance training was when I took a course in Improvisation under Agnes Locsin, Cultural Center of the Philippines Awardee for Dance.  It was here that I learned to explore the use of my body and find new approaches to its use.  Specifically, I learned how I can move my arms and my legs in novel ways that were beautiful to behold and felt good to me, the performer.

Do you need to have any dance training to improvise and explore the use of your body? No. As a matter of fact, those who do not have any dance training are able to explore better because they do not have any movement biases.  It is more challenging for me to teach ballet dancers Improvisation because they are so concerned about technique. 

So how does one start improvisation. One way is to write your name with a specific part of your body. ( I will save this interesting exercise for another post. ) Another way, is by Mirroring.  In this exercise, 2 performers face each other with one designated as leader and the other as follower.  The leader moves a part of his/her body slowly with the follower copying the movement just like a mirror image.  Being challenged by my students ballet mindset, I started the exercise by having the leader do 2 movement phrases of 8 counts each, which I just improvised.  The follower was to do the usual following as the leader did my phrases. This was all done to establish the experience of being leader and follower among the dancers.

Having established the relationship between follower and leader, I then had the latter create her own phrase.  AS expected, her fear of technical incorrectness led her to make conservative hand moments. At this point, I directed the leader to go to a door frame in the studio and try to make movement that related to the frame.  I told her to explore moving at different levels.  My only constraint was for her to move in a  slow, steady manner. After she found her movement phrases, I had the leader go back to her pair and introduced the additional constraints of not turning her back to the follower. I had the leader 16 counts of her own movement before eliminating my movement phrases.  It was a pleasant suprise for my dance to have created her own movement. After completing the exercise. I had the leader/follower roles switched.  Below is a video clip showing the mirroring exercise done by my students for Acts Manila @ Life N Arts Sta Rosa Laguna.

Biometric Voter Registration Process Philippines

The deadline for Biometric voter registration in the Philippines is coming up in the next few days.  As the COMELEC's campaign slogan goes, No Bio...No Boto...This just emphasizes the importance of this process to ensuring our voice as citizens are heard.  In general the process was smooth except for the volume of people that were queuing up for registration.  The process goes in 4 steps are shown in the infographic below. I've also put a short video to take you through the Registration Process.



 


Hope this helps you out in the next few days.
