Summary of Chap 2, 3 & 4 - Quick Review / Revision of Lessons Using Charts and Mind Maps

Summary of Chap 2, 3 & 4 - An Overview

This real-time mind map summary was done for my students as part of a quick review / revision for Chapters 2, 3 and 4. It provides them with a quick guide as to the KEY points covered during lectures. 

However, students have to read up the powerpoint lecture notes if they do not understand or forgot what the key words used in the mind map meant. Enjoy.

Chap4 - Quick Review / Revision of Lessons Using Charts and Mind Maps

Chap 4 - Heat Treatment Processes


This is not a mind map. It is just a summary that I did to show how the Phase Diagram used in Chap 3 is used to show where the Heat Treatment processes [ Hardening, Full Annealing, Spheriodisation, Process Annealing ( Stress Relief Process) Normalising ] are in relationship to the Upper Critical Temperature and Lower Critical Temperature.

Students going through this Chap 4 were also shown how the traditional Katana Samurai sword was made. The hardening process involving the heating to its austenitising temperature, is followed by the quenching process as well as the tempering process.

The range of the tempering chart is shown together along side with parameters such as %elongation, %Area reduction, Yield Strength, Ultimate Tensile Strength and Impact value. To be a Master in making the sword obviously involves intimate knowledge of the heating, cooling and tempering process as well as the material that goes to make the sword.

Well, what do you think is the %carbon content in a Katana Samurai Sword?

Chap 2 - Quick Review / Revision of Lessons Using Charts and Mind Maps

Chap 2: Properties and Different Types of Mechanical Tests
 







 
























This quick review of Chap 2 mind map would provide a summary of the various topics covered, namely, properties ( Physical and Mechanical ) plus some of the main types of mechanical tests ( Tensile, Hardness, Impact,  Creep and Fatigue ).

Students need to dutifully read through their lecture notes and then associate what they have read with the key words found in the mind map above. Only then, would the above mind map be extremely useful. I just could not imagine a world without mind maps. Please enjoy.

GIGO versus GIGG

I was reading Edward de Bono's "New Thinking for the New Millennium" when I came across an expression GIGO (Garbage In, Garbage Out) commonly used term in the computer world. Dr Edward de Bono stated that this computer logic "is the same with human logic. If the starting perceptions are faulty or inadequate, then flawless logic will produce absurd answers. But, much more dangerously, we will believe those answers to be valid."

The GIGO expression reminded me of Tony Buzan's book "Head First". He wrote that the computer GIGO logic that was thought to be true as to how the human brain thinks for many years, was in fact NOT TRUE. He emphasised that the human brain thinks, (in a more graphical way) as GIGG - i.e. Garbage In, Garbage Grows! 

He wrote that, "armed with this new information we can reconsider the idea that our synergetic brain is self-creative" as well as the fact with "the GIGG equation, the human brain can also be synergetically destroyed when rubbish or pollution infiltrates its incredibly sophisticated and complex systems....." eventually leading to "instances of suicides, murders, wars," and acts of unexplained shootings and killings in many parts of the world. How do we prevent this from happening? Apparantly, we need all to understand how the BRAIN really functions!

From my many observations, I have seen that a lack of understanding of this knowledge about the BRAIN has led to many individuals/groups "being led" to the path of "no return". Likewise, individuals/governments/countries with knowledge of how the brain functions may be able to save or pull some of these individuals to the "right path", from being depressed, individual/mass suicidal packs, or committing many unexplainable acts that we see today.

However, it is easier said than done. In the first place, the troubled individual / group needs to voice out their concerns. Sometime they communicate, but, no one seem to listen to them. Most of the times they may choose to remain silent and then, exercise their dissatisfaction through some non-violent acts like the ballot box, street demonstrations, etc... So....How could to we solve this BRAIN problem? Haha. How do we win the TRUST of these troubled individuals/group in order to win or turn them over? It is not easy......! I believe, lots of hard work is needed, sincerity in helping and giving would certainly be one of the ways.

Thus, to summarise this post in very simple terms, I would look at GIGO as how computer logic works and GIGG as how the synergetic human brain thinks. It is important to recognise this Brain Principle of Synergy. The reader may wish to explore other Brain Principles in Tony's book "Head First". Alternatively, the reader is also invited to view the various Brain Principles in a Mind Map that I did during Tony's two-day workshop in Singapore [ CLICK HERE ]
and
an excellent TEDx presentation on "The Power of a Mind to Map" that he gave in Dec 2012 [ CLICK HERE ]!

Enjoy! Thanks.

Chinese Tsunami vs Malaysian Tsunami

The Malaysian General Election (5 May 2013) ended with the Barisan Nasional (BN) forming the next government. What is interesting are some key words mentioned by prominent players. They are, "Chinese Tsunami" by the Prime Minister of Malaysia, Datuk Seri Najib Razak and "Malaysian Tsunami" by Lim Kit Siang, the DAP Parliamentary Leader and MP for Gelang Patah (2013).

The words reminded me of the 13 May 1969 incident, where racial riots broke out in Malaysia after the general election. Would it happen again because of the above "words"? I hope not! It is probably best to maintain racial and religious harmony among all races, listen to the needs of the people and work hard to win over the minds and souls rather than blaming or playing one race against another.

Again, as mentioned in my earlier mind map on "Crucial Conversation"  [CLICK HERE], it is important to seriously uncover matters that lies hidden in the minds of the people. Here is where the hard work of the government and all elected representative comes in. Can they win the trust of the people? Would they be able to fathom into the issues facing the people? Would they be able to plan, organise and implement issues/projects critical for the country's survival/sustainability instead of, for the party's? Have they not learnt lessons from the previous elections so as not to repeat the painful experience again? It takes a strong person /government with an ability to accept CHANGE, to admit that there has/have been honest mistake(s) made, work hard to correct it and move ahead to implement good project(s) for the country without prejudice to anyone.

However, no real progress would be made, if corruption of any kind exists in the system.

I am glad that we take racial and religious harmony and upholding of incorruptibility in Singapore very seriously and not let any political parties or any organisations / individuals undermine these important National Education (NE) Messages [CLICK HERE] all Singaporeans would treasure very much. 

I believe, I have travelled quite widely. I think I have always been a strong advocate of encouraging Singaporeans to travel to as many parts of the world as possible and learnt all they can about the people and the country that they have visited. The Internet may help. But, nothing beats first hand experiences. I believe, it will help to strengthen Singaporeans' belief of the six NE messages. Thank you.
