Special Year of 2011

This year we are going to experience 4 unusual dates.1/1/11, 1/11/11, 11/1/11, 11/11/11 and that's not all... Take the last 2 digits of the year in which you were born.... now add the age you will be this year, and the result will be 111 for everyone!!! 

For example - Harry was born in 1957 and will be 54 this year, so 57+54=111....Good eh!!!!!!!! This is the year of money!!! Also this year October will have 5 Saturdays, 5 Sundays and 5 Mondays. This happens only once in 823 years.

Update syllabus, eBworx urges Malaysian varsities

BEING a local graduate himself, eBworx Bhd's (0030) group chief executive officer Tan Suan Fong says local universities are not churning out the right type of graduates that are ready for the workforce.

"We find that when we employ these local graduates, we need to train them more as there is no learning curve," he told the Business Times in an interview recently.
Tan, an engineering graduate from Universiti Malaya, hoped local universities will update their syllabus to be able to adapt its students to the working world.

Having said that, Tan feels that Malaysian graduates have good work ethics and is still planning to hire another 10 to 15 per cent of Malaysians to join the company he founded this year.
"We are hiring around another 35 per cent more. Out of that, 20 per cent will be from Jakarta, Indonesia and also Chengdu in China as they have a lot of good talent there," he said.

On why eBworx was not looking at India, which is known as the hub for information technology (IT) experts in the world, Tan said it was because its expertise came at a very hefty price.

"Everyone is going to India to source for IT experts, and usually the best ones are all taken up by US- and European-based companies. So what is left for us when we get there is not the cream of the crop," he added.

Physics Form 4: Chapter 2 - Momentum

  • Momentum is defined as the product of mass and velocity.
  •  The principle of conservation of momentum states that in a system of collision or explosion, the total momentum is constant if no external force is acted upon the system.
Total Momentum Before Reaction = Total Momentum After Reaction
  • Elastic collision is the collision where the kinetic energy is conserved after the collision.
     


    Inelastic collision is the collision where the kinetic energy is not conserved after the collision.

Support Earth Hour 2011

At 8:30 PM on Saturday 26th March 2011, lights will switch off around the globe for Earth Hour.




Countries like Japan, North America,  coastal China and Europe were so brightly lit at night. The more developed of the country, the brighter the sky at night and the more electricity they consumed. Hence, more and more fossil fuels have to be burnt to generate electricity to meet the increasingly power demand. Releasing too much carbon dioxide to the atmosphere will only accelerate global warming phenomenon. 

I really hope that the earth will be completely in dark on 26th March 2011 at night. Let's support EARTH HOUR 2011.

Physics Form 5: Chapter 2 - Current and Potential Difference


  • Current is the rate of flow of charge.
  • The flow of current is due to the flow of electrons in conductor.
  • Direction of current flow is opposite to the direction of electron flow.
 

  •  Potential difference is the work done to flow one unit of charge from one point to another point.
  • Unit of potential difference is volt.

 Consider the task of moving a charge within a uniform electric field from location A to location B. In moving the charge against the electric field from location A to location B, work will have to be done on the charge by an external force. The work done on the charge changes its potential energy to a higher value; and the amount of work that is done is equal to the change in the potential energy. As a result of this change in potential energy, there is also a difference in electric potential between locations A and B. This difference in electric potential is  formally referred to as the electric potential difference

Physics Form 4: Chapter 2 -Graph of Motion

Displacement-Time Graph:

  • Gradient of the graph is equal to velocity
  • Gradient = 0 , velocity = 0.
  • Gradient is negative and constant, hence velocity is uniform and in opposite direction.
  • Gradient is increasing, hence velocity is increasing.


 Velocity-Time Graph:

  •  The gradient of the velocity-time graph gives acceleration.
  • Gradient = 0, hence velocity is constant but acceleration = 0.
  • The area below the velocity-time graph gives a value of the object's displacement.

    Earthquake + Tsunami + Nuclear Radiation in Japan

    Forget about Japanese atrocities during World War 2, forget about Nanjing massacre and Japanese invasion into Malaya. Take away these past bad memories from us. Let us start forgive and love each other. God loves Japanese also. In togetherness, we pray for peace in Japan. 

    Physics Form 5: Chapter 2 - Electric Charge

    • There are two types of electric charge namely positive charge and negative charge.
    • Like charge repel each other.
    • Unlike charge attract each other
    • Unit of charge is Coulomb, C.
    •  Electric field is a region where a charge experiences electrical force.
    • Lines of force are used to represent the direction of an electric field.
     

    Candle in the electric field
    • Heat energy from the candle flame produces ionization of air molecules to form positive and negative ions.
    • Movement of positive ions which are heavier towards the negative plate causes a bigger spread of the flame.
    • Negative ions which are lighter move towards the positive plate and causing a smaller spread of the flame.

    Chemistry Form 4: Chapter 3 - Experiment of Magnesium Oxide Empirical Formula

    Procedure of the experiment:

    • Magnesium ribbon is cleaned with sandpaper to remove the oxide layer on its surface.
    • The lid is removed at intervals to allow oxygen to enter the crucible and react with magnesium.
    • The crucible is then quickly covered with its lid to prevent the white fumes of MgO from escaping.
    • Heating, cooling and weighing are repeated until a constant mass is obtained to ensure that the magnesium ribbon reacts completely with oxygen gas.
    The white powder is magnesium oxide

    Sometimes, God uses blue ball pathway to train and make us stronger. The path that the God set for us is a path of valleys and hills. It is not all flat or downhill. If life were always smooth and level as shown in red ball pathway, the boring sameness would weigh and slow us down. We need the valleys and hills, ups and downs in our life.  The hills collect the rain for hundreds of fruitful valleys. Therefore, a path of valleys and hills make us accelerate .....

    Again, Another Malaysian Made It On Top of the World

    JESSICA Quah Xiao Ling has made Penang proud when she scored 100% in English language during the University of Cambridge’s International GCE A-level exam. The 19-year-old lass, who is pursuing her A-level studies at the International School of Penang Uplands, was declared the best scorer in English language paper among students worldwide who sat for the examination in November last year.

    She also scored 99% for Economics and 95% for Mathematics.
    The former SMK Convent Green Lane student said lady luck could have contributed to her success as she did not expect to score full marks in a language subject. Quah said she knew she had done well when the result was announced on Jan 24 but did not expect to be the best among the world’s candidates.

    She added that she was equally surprised when she was invited to attend the Outstanding Cambridge Learner’s Award Ceremony in Subang Jaya on Feb 22.  She also paid tribute to her mother, a part-time English teacher, for her encouragement to her and her sister to improve their English through constant reading.
    Quah, who scored 5As in UPSR, 7As in PMR and 8A+s and 2As in her SPM, praised her teachers who trained the students to be independent in realising their potential.

    The school’s assistant principal John Cadman, who is Quah’s personal English teacher, described her as one of his best students throughout his 42 years of teaching. “I have never given her a 100% in English as I have always told her only God will be that perfect. “Her sensitivity in literature and music enables her to express herself better.

    “She certainly deserves the award for she has always been very active and attentive in class,” he added.
    Quah, who will complete her A-level in June, hopes to pursue a double-major in music and English creative writing in the United States or Britain.

    “I have received several offers for scholarships and am currently waiting for details from the universities,” she said, adding that her ambition might be to teach English and Music.

    Physics Form 5: Chapter 1 - Application of Destructive Interference

    Noise Cancellation
    • Noise cancellation is a method to reduce or completely cancel out undesirable sound.
    • A noise-cancellation speaker emits a sound wave with the same amplitude, frequency but anti-phase with the original sound.
    • The waves will combine each other in a process called destructive interference, eventually the waves will cancel each other and there would be no sound.
    • The sum of the waves is equal to zero.


    Application of noise cancellation:
    1.  Headphone - people working near aircraft or in noisy factories can now wear these electronic noise cancellation headsets to protect their hearing.
    2. Cars - The way it works is that a microphone connected to the car stereo system picks up all the sound inside the car, including music or such from the stereo. Then the noise-cancellation system subtracts the sound of the music coming from the stereo and produces noise-canceling sound waves that match the frequency of unwanted sound.
    3. Aircraft - The system uses microphones to pick up the vibrations due to jet's engine in the cabin walls. It then analyzes the signals and generates counter vibrations in the walls to produce a net result of zero vibrations.

    Do we use logical thinking?

    In solving mathematics and science problems, we need logical and rationale thinking. Somehow, there is still some people who do not use it. Enjoy yourselves below these photos.



    Ha, ha....Don't laugh at others. Sometimes, we also do silly things

    Physics Form 5: Chapter 1 - Refraction of Sound Wave

    • During day, the layers of air near the ground is warmer than the layers of air higher up.
    • Air layer near the ground is less dense.
    • Therefore, sound wave is bent toward the normal.

    •  At night, the layers of air near the ground is cool faster than the layers of air higher up.
    •  Air layer near the ground is denser.
    • Sound travels faster in warm air than in cool air resulting increasing of wavelength.
    • When the angle of incidence is larger than the critical angle, total internal reflection occurs.
    • Therefore, the path of the sound curves reflects downwards and you can hear the sound easily at night.
