Science is based on observation and experiment.

the questions: «How?» and «Why?»
They try to explain the world

from the material point of view.
They explore things that are mysteries to us and do research.
They study physical objects and observe different processes and phenomena.

they suggest new ideas, put forward theories and set out

laws.
Scientists make experiments and discover various facts .
Finally, they state(establish) and formulate the principles of these theories.

science progresses.
In some centuries people mostly store, save and preserve

information.
But there are centuries that are rich in numerous important discoveries and inventions.
For example, the 19th and the 20th centuries saw the greatest inventions indeed.

as real breakthroughs?
There is a legend that they

are the fire, the wheel and the alphabet as they gave humanity power over matter, space and symbols relatively.
The other widely spread idea is that the compass, (gun)powder and paper are most influential inventions in the history of mankind.
But in fact there are lots of them.

we can’t do without science nowadays.
There are 2

major reasons for that.
Apart from those who are keen on receiving knowledge, getting new information just for the fun of it or to broaden their own horizons, we can’t ignore the fact we live in a certain environment.

everything around us better. It is essential not to get

into trouble, to provide ourselves with a healthy place to live in.
Besides it is a well-known fact that science affects nearly every area of common people’s lives through technology.

environment. It sets the scene in which we act. If

it couldn’t do that, we’d be blind and ignorant and couldn’t act reasonably at all.”
(Magnus Pyke, a British scientist)
“Science clears the fields on which technology can build.”
(Werner Heisenberg, a German scientist)

exciting time in the history of science. Modern methods of

research enable us to understand many things that were mysterious to our ancestors. We are increasing our understanding of the universe.
But the more we find out the more we realize how much there is still to learn.

minds are working at, to mention only a few:
Finding alternative

sources of energy
Recycling and reusing materials
Creating effective systems of communication
