Science is the study of natural phenomena through reasoned investigation to discover new principles and knowledge. The natural sciences study nature while social sciences study human behavior and society. Engineering applies math and science principles to design, create, and improve tools and systems to meet human needs, and is divided into several disciplines. Technology utilizes scientific knowledge for practical applications in industry and commerce through products, processes, and systems. Scientists, engineers, and technologists work to advance knowledge and develop solutions that benefit society.

1.  Comes from the Latin "scientia“ means
KNOWLEDGE
 Knowledge attained through study orpractice
 Reasoned investigation or study of natural
phenomena with the objective of discovering new
principles and knowledge of natural phenomena.
 produces useful models ofreality.
 Natural sciences, the study of the natural world
 Social sciences, the systematic study of human
behavior and society.

2.  Practical application of science to
commerce or industry
 includes the skill, technique and knowledge
of the manipulation of nature for human
purposes, using scientific results and
knowledge.
 Improvisation of a preexisting solution to
produce a function dependent solution.

3.  Practical application of math andscience.
 design, create and production of new tools,
machines and systems for practical human
means by exploiting technology.
 Divided into several disciplines and sub
disciplines
 Broadly dividedinto…
 Chemical Engineering
 Civil Engineering
 Mechanical Engineering
 Electrical Engineering

4. The Earth
is moving
around the
Sun.
The Earth is
the center of
the universe.
the Sun revolved
around the Earth
and the other
planets revolved
around the Sun.
Ptolemy

5.  Higgs field - is a possibly quantum field supposed to
be responsible for giving elementary particles
their masses.
 Boson - a type of particle that allows multiple
identical particles to exist in the same place in the
same quantum state
 Church : God created the universe and all in it. God gave
everything it’s structure, purpose, live and yesit’s mass.
 Higgs Boson - what are we made out of.
 The missing piece of the puzzle to understandthe
world

6. Is it the air?? The smoke?? The fog??? …. Oh!
It’s the Steam 
 A small step for 3 men, a giant leap for
mankind.
 Works on the Principle of Complete or Partial
Vacuum with a Condenser.
 First Practically used to pump Water From Coal
Mines.
 James Watt credited for the major
Developments.

7.  Diabetes is caused by the lack of insulin
production known as hyperglycemia.
 Insulin is a hormone which is produced
by the pancreas.
 In 1921 Fredetick ,G. Banting and Charles
H. Best discovered an "anti- diabetic
factor“ in the dog's pancreas.
 In 1922 the effective treatment of
diabetes is discovered in Toronto.

8. At first humans realized that heavy
objects could be moved easier if
something round was placed under it
and the object rolled over it.
Then logs were placed under an
object to drag it easily. This was
the invention of sledge.
With time the sledges started to wear
grooves into the rollers and humans noticed
that the grooved rollers actually worked
better, carrying the object further.

9. Then the rollers were changed into
wheels & the first wooden cart was
made.
Next, the fixed axle was invented,
where the axle does not turn but is
solidly connected to the cart frame.
After that different two wheelers,four
wheelers etc are developed.

10.  In 1642 Blaise Pascal
(1623-1662) invented an
adding machine named
pascaline.
 Thirty years after Pascal,
Leibniz devises a calculator
which allows to easily
multiply and divide
 The first automation of
addition (subtraction) is
probably the work of
Wilhem Schickard in 1623
 The first easy to use
calculator(Arithmometer)
has been designed in 1820
by the French Thomas de
Colmar.

11. Scientists seek to under
stand need new tools to help
the natural world, and often
discover the answers.
Engineers use scientific
discoveries to design
products and processes
that meets society needs.
Technologies (products and processes) are the result of
engineered designs. They are created by technicians to
solve societal needs and wants.
