This oft repeated proverb has a wealth of meaning

hidden behind it. It illustrates the importance of time

and drives home the fact that there is nothing more

precious than time . Just as tides that come as waves

in the sea do not last forever and go back as fast as

they come, time too does not stop or wait for any one.

Like all proverbs, this too has an interesting story

behind it

Once there was a king whose courtiers always kept on

flattering him and announced that if the king

ordered everything to stop, the world too would stop

working

Now the King wanted to check it and he went to the

seashore and ordered the waves to stop but nothing

happened. This made the king realise that nothing in

the world waits for anyone. He turned to his courtiers

and announced solemnly that time and tide wait for

none and that he too would be gone one day

Therefore dear children, if we procrastinate and

become an expert in wasting time, it’s we who are

going to bear the consequences.

Idlers and shirkers not only destroy their own future

but also of the nation

Hence do not waste even a minute of your precious life

and use it fruitfully and judiciously so that you are

richly rewarded for your efforts

Over billions of years, microorganisms and plants

evolved the remarkable process we know as photosynthesis.

Photosynthesis converts sun energy into chemical energy, thus providing

all life on Earth with food and oxygen. The cellular compartments housing

the molecular machines, the chloroplasts, are probably the most important

natural engines on earth. Many scientists consider artificially rebuilding

and controlling the photosynthetic process the "Apollo project ." It would

mean the ability to produce clean energy—clean fuel, clean carbon

compounds such as antibiotics, and other products simply from light and

carbon dioxide.

Marburg research team led by director Tobias Erb has succeeded

successfully created a platform for the automated construction of cell-sized

photosynthetically active compartments, "artificial chloroplasts," that are

able to capture and convert the greenhouse gas carbon dioxide with light..

Did you know that you have 43 different pairs of nerves that connect your

central nervous system to the rest of your body, and that 12 of these nerve

pairs connect to the brain, while the remaining ones connect with the spinal

cord?

There are more nerve cells in the human brain than there are stars in the

Milky Way.

If we lined up all the neurons in our body it would be around 965 km long.

The left side of human brain controls the right side of the body and the right

side of the brain controls the left side of the body.

There are 100 billion neurons in your brain alone.

A newborn baby's brain almost triples in size during the course of its first

year.

The longest nerve in the body is the sciatic nerve. It runs from the spinal cord

to the toes on each side of the body.
