Science

Comes from the Latin "scientia“ means KNOWLEDGE

Knowledge attained through study or practice Reasoned investigation or study of natural

phenomena with the objective of discovering new principles and knowledge of natural phenomena.

produces useful models of reality. Natural sciences, the study of the natural world Social sciences, the systematic study of human

behavior and society.

Technology

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.

Engineering

Practical application of math and science. 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 divided into…

Chemical Engineering Civil Engineering Mechanical Engineering Electrical Engineering

Sun & Earth

The Earth is moving

around the Sun.

ScienceThe Earth is the center

of the universe.

the Sun revolved around

the Earth and the other planets

revolved around the Sun.

Ptolemy

Tycho Brahe

Copernicus

The Earth and the other

planets orbit the

Sun.

Galilio

God Particle

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 yes it’s mass.

Higgs Boson - what are we made out of. The missing piece of the puzzle to understand the

world

Science

Technology Steam EngineIs 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.

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.

INSULIN

Technology

WheelAt first humans realized that heavyobjects could be moved easier if something round was placed under itand 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.

Engineering

Wheel Cont..

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.

Engineering Calculators 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.

Relationship

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 ofengineered designs. They are created by technicians tosolve societal needs and wants.

Application

As knowledgeThrough the knowledge of Science, Technology and Engineering, the world has produced Scientists, Technologists and Engineers who contributed maximum for the benefit of human beings, the society and the world at large.

As Social ActivityApplication of Science, Technology and Engineering has made mankind a civilized sociable person.

As Professional ActivityTo-day Science, technology and Engineering have developed so much to absorb large number of people for their main occupation and profession.

Gene  Molecular unit of heredity of a

living organism Evolving with the science

of genetics Existence of genes was first

suggested by Gregor Mendel

Provides the opportunity to improve human and animal health

Alteration of certain probabilistic aspects of heredity is possible
