Generally our thinking tends to be Re-productive, i.e.

based on similar problems encountered in the past, or

taught to solve.

However, we must learn to do Productive thinking, i.e.

generate as many alternative approaches as possible.

Creativity

Page 4: THINKING SKILLS Creativity, Problem solving, Problem finding.

• Creativity is a skill which can be developed by practice.

Conscious application is needed, not the vagaries of

“inspiration”, in order to achieve a creative output.

• “That “creativity” is beyond analysis is a romantic

illusion we must now outgrow” – Peter Medawar.

• Creativity is a matter of organizing one’s basic skills,

not regretting that one was not born with a “quick”

or “logical” mind.

GIFT OR SKILL ?

Page 5: THINKING SKILLS Creativity, Problem solving, Problem finding.

• Marilyn vos Savant (IQ 228 – highest ever) is

merely a question and answer columnist for

Parade magazine.

• Richard Feynman (IQ 122 - less than many run-

of-the-mill physicists) is a Nobel prize winner

and recognized as the last American Genius.

INTELLIGENCE versus CREATIVITY

Page 6: THINKING SKILLS Creativity, Problem solving, Problem finding.

Intelligence and creativity are not the same things.

Intelligence in a domain means the ability to

function at a high level in that domain, but

creativity involves asking new questions and

altering the domain. One can be highly intelligent

but rigid, noncreative, or lacking in the kind of

single-minded passion that drives creators.

INTELLIGENCE versus CREATIVITY

Page 7: THINKING SKILLS Creativity, Problem solving, Problem finding.

Creativity is the ability to look at the same thing

as everyone else and think something different.

Description of attitudes with the help of “roses” and “thorns”

Humane Roses for you and Roses for me

Optimistic Roses

Pessimistic Thorns

Realistic Roses and thorns

Stoic Roses or

thorns

Selfish Roses for me and thorns for you

Sadistic Thorns for you and your blood for

meDivine Roses for you and your thorns for me

Page 9: THINKING SKILLS Creativity, Problem solving, Problem finding.

Creativity can be developed by -

• Looking at the world in terms of analogies.

• Learning about different ways to solve a problem

If you have 10 hours for chopping a tree,

spend 5 hours sharpening the axe.

PRESCRIPTIONS

Examples of Analogies

• Solar system Atomic structure

• Brownian motion of dust particles

Electrons in a crystal

Page 11: THINKING SKILLS Creativity, Problem solving, Problem finding.

Different ways of calculating

• 22 < < 4 (square), 3 < < 23 (hexagon)

• / 4 = Tan-1 1 = (x – x3/3 + x5/5 – x7/7 + ….) at x = 1

• Buffon’s needle experiment

= 2 x (total drops) / (no. of hits)

Education is not about learning diverse

subjects, but about learning diverse ways

to the same subject - Aurobindo

Derive the trend in the behavior of plating adhesion

on a silicon substrate from the measured data as a

function of substrate area and doping level. The

adhesion is measured for 0.5, 1 and 2 cm2 area, and

P+, P, N and N+ doping levels. Each measurement

is repeated twice.

PROBLEM FINDING

Page 21: THINKING SKILLS Creativity, Problem solving, Problem finding.

• Problem solving versus problem finding

• Formulation of a problem

• Types and attributes of research problems

• Sources of research problems

CONTENTS

Page 22: THINKING SKILLS Creativity, Problem solving, Problem finding.

Finding a problem

• is harder than solving it or doing the actual

research;

• is often more essential than its solution;

• is as much a scholar’s responsibility as that of the guide - a problem must spring from a researcher’s mind like a plant springing from its own seed.

Problem Solving vs Problem Finding

Page 23: THINKING SKILLS Creativity, Problem solving, Problem finding.

Attributes of Research Problems

Difficulty

Value or usefulness

Originality

Is it interesting (does it deny commonly held assumptions ?)

Significance / impact (all the above and more)

Cost / equipment / cooperation

• What to read

• How much to read

• How to read

• Note taking

LITERATURE SURVEY

EXPERIMENTAL AND MODELING SKILLS

Page 26: THINKING SKILLS Creativity, Problem solving, Problem finding.

CONTENTS

• Scientific method

• Design of an experiment

• Need for precision

• Errors – types, sources, estimation

and elimination

• Documentation

Page 27: THINKING SKILLS Creativity, Problem solving, Problem finding.

SCIENTIFIC METHOD

Non-scientific thinking

• Authority

• Pure logic

• Intuition: spontaneous judgment not based on

conscious reasoning.

common sense: practical intelligence shared by

a large group of people

These are “practical” rather than theoretical.

Scientific results can be counterintuitive

Page 28: THINKING SKILLS Creativity, Problem solving, Problem finding.

• Observation

• Hypothesis

• Verification

• Generalization

• Experiment

• Observation

• Inference

SCIENTIFIC METHOD

Page 29: THINKING SKILLS Creativity, Problem solving, Problem finding.

Hypothesis is an imaginative preconception or an

inspired guess about some particularly interesting

aspect of the world. Every discovery begins as a

hypothesis.

Experiment is the act undertaken to verify a hypothesis.

SCIENTIFIC METHOD

Page 30: THINKING SKILLS Creativity, Problem solving, Problem finding.

• A way of understanding the world by objective

observations.

• Its goal is to discover laws and develop theories

to explain them.

SCIENTIFIC METHOD

Page 31: THINKING SKILLS Creativity, Problem solving, Problem finding.

• Law:

A statement that certain events are regularly

associated with each other in an orderly way.

• Theory:

A set of statements explaining one or more laws,

usually including one indirect concept needed to

explain the relationship

SCIENTIFIC METHOD

Attention span

It can be increased by adding variety to the talk -

interaction, diagrams, audiovisuals, pace of speech,

pitch of the voice, length of sentences, pauses,

repetition; gesturing with hands, humor.

Attention span of the audience: initial 20 min of

concentration, lapse for 10-20 min, slight recovery

and then renewed relapse till the end.

Page 38: THINKING SKILLS Creativity, Problem solving, Problem finding.

WRITING AND THOUGHT

• Writing is the means of discovering new knowledge.

• Writing makes people think about their work in a different way.

• The only time when we think is when we write !

• A lot is written when little has been achieved.

Page 39: THINKING SKILLS Creativity, Problem solving, Problem finding.

Prescriptions

• Read the editorial of newspapers daily.

• Read the newspaper aloud.

• Do writing for two hours / week .

This could be notes for the lectures that

you gave, or description of an important

idea. It can also be precis writing.

"I am arrive by passenger train Ahmedpur station and my

belly is much swelling with jackfruit. I am therefore went

to privy. Just I doing the nuisance that guard making

whistle blow for train to go off and I am running with lotah

in one hand and dhoti in the next when I am fall over

and expose all my shocking to man and female women

on platform. I am got leaved at Ahmedpur station. This

too much bad, if passenger go to make dung that dam

guard not wait train five minutes for him. I am therefore

pray your honour to make big fine on that guard for public

sake. Otherwise I making big report in papers."

Okhil Chandra Sen to Sahibganj Divisional Railway Office (1909)

MANAGEMENT SKILLS

Page 42: THINKING SKILLS Creativity, Problem solving, Problem finding.

We cannot say – go and discover the second law of

thermodynamics in the afternoon, but if we arrange

our schedule so as to set aside time for thinking and

experimenting, we put ourselves in the way of

discovering something.

Time managementTime management

Working out a new idea requires much routine work,

and to this part of an investigation, we can apply

efficiency methods.

Page 43: THINKING SKILLS Creativity, Problem solving, Problem finding.

Persistence and the ability to manage boredom and

frustration are crucial for research work.

Stress managementStress management

Monotony and repetitiveness of concentrating on the

same idea for an extended period of time.

Criticism

Loneliness: “I work alone in a lab, full of people - all

research students, all working alone.”

Sources of stress

Page 44: THINKING SKILLS Creativity, Problem solving, Problem finding.

Professional EthicsProfessional Ethics

• Research, like all good things in life, is never smooth

sailing

• Plagiarism - cite reference

• Credit to co-workers – authorship and acknowledgment

Page 45: THINKING SKILLS Creativity, Problem solving, Problem finding.

CONCLUSION

• During research, the feelings of exploration, excitement,

challenge, involvement and passion are frequent, and

one gets an enormous feeling of achievement on the

award of a research degree.

• Research makes you an independent and organized

thinker, a good communicator and stress-time manager.

• Education is not about learning diverse subjects,

but about learning diverse ways to the same subject.
