Great Inventors and the Driving Force behind their Inventions

Ten of the greatest inventors who helped change the world.

1. Thomas Edison (1847 – 1931)Edison filed over 1,000 patents. He developed and innovated a wide range of products from the electric light bulb to the phonograph and motion picture camera.

2. The Wright Brothers – Successfully designed, built and flew the first powered aircraft, showing that man could fly. One of most important inventions of Twentieth Century.

3. Benjamin Franklin (1705 – 1790) Polymath who discovered electricity and invented the Franklin stove.

4. Nikola Tesla (1856 –1943) Serbian born scientist who emigrated to the US. He was a brilliant scientist who played a key role in the development of AC electricity – through the AC induction motor, transformer, and Tesla coil. His method of AC electricity has been the template for global electricity use.

6. James Watt (1736 – 1819) Inventor of the steam engine, which was critical in the industrial revolution. His invention of a separate condensing chamber, greatly improved the efficiency of steam.

7. Alexander Bell (1847 – 1922) Credited with inventing the first practical telephone. Also worked on optical telecommunications, aeronautics and hydrofoils.

8. Leonardo Da Vinci (1452 – 1519) One of the greatest ever minds, invented models that proved workable 3-500 years later.

9. Galileo (1564-1642) Developed a powerful telescope and confirmed revolutionary theories about the nature of the world. Also developed an 

India at the Rio Olympics

It was famous, don't you see,

Indian athletes did well at the opening ceremony

Carrying the tricolor proudly

Hoping to win medals in swimming, shooting and archery!

But alas it was not destined to be!

Competitors with keener eyes, swept all the medals away in a trice!

Gold, Silver and even Bronze

Slipped away from our countries grasp!

Now the situation was do or die!

With few days to go before the final sigh!

Dipa tried extremely hard! Just fell short of a vault!

Then on Raksha Bandhan day

Sakshi and Sindhu made the day

A bronze and silver won they!

What joy! What a triumph for all that day!

When the Games were finally over!

All were left with some shreds of bother!

If only we had all tried harder!

Sent children to play instead of reading Harry Potter!

If only sports had more importance in the scheme of things

It would not have been so few medals at the Rio Olympics!

Compilation of Famous Quotes on science & character by famous people

Evolution of Man

By 2040, cabs will be driven by Google robots, shops will become showrooms for online outlets and call centres will be staffed by intelligent droids.

That’s the scenario depicted in recent research which suggests robots could be taking over our lives and jobs in less than 30 years.

The competition for work caused by a rise in the robots population will see us heading to surgeons for ‘additional processing power for our brains’, they claim.

We may also be requesting bionic implants for our hands that will make us able to perform tasks as fast as any machine.

Futurologists, commissioned by global job search website xpatjobs.com, say workers will have less job security and will work more unsociable hours.

Those who take these risks and innovate with their own bodies will be the biggest earners in 2040, they claim.

However, the study added that workers may be left with poor eyesight, smaller sexual organs, and constantly-furrowed brows as they struggle to keep up to life in the 21st century.

Difference between the sexes may cease to exist. This will slow down reproduction rates and lead to dwindling of the earth's population in a natural manner.

My poem for Young Girls on the occasion of Women’s Day

You are sixteen going on seventeen

If its a career in science u are aiming

Coaching classes will fall in line,

To go for Physics, Chemistry, Bio or Mathematics

The choice is really yours!

In Physics don’t forget Newton’s laws are waiting

Electromagnetism, modern physics turn on the heat

Chemistry is full of equations on organic 

Sulpher, Phosphorous and Chlorine u'll be making

Differentiation and Integration are lurking

If it’s maths u are mastering

If it’s a doctor u are aiming to be

Enzymes, hormones and diseases are ur cup of tea

Don’t forget that at your tender age

You can’t really know 

What’s right for u

But follow your heart 

And surely baby

Everything will turn out right for u!

Start of Std 12 Board Exams

Sona's board exams started on 1st March. It was a really hectic process, deciding who will drop her , pick her, accompany her to the room etc. She at first refused to let us fussy old parents near her. It is big insult for a girl her age to be accompanied by those unwanted yet necessary appendages- parents. I recollect faintly having such feelings for my parents, but not nearly as fervent as her feelings are. After the English exam was over she reluctantly revealed that the fan in her classroom was not working. I demanded immediately to know whether any of the students had reported it to the authorities, but it seemed that no one had. I immediately decided to do something about it, though Sum didn't agree with me. I tried to call up the school but no one picked up, so I wrote a mail instead and lo behold there was a reply a few hours later which confused me. I had written a nice and proper letter to them 

Dear  Madam,

                          My child is appearing for the Std 12 Board examination and the exam centre is at your reputed school in the seventh standard classroom. Unfortunately during the first exam in English on 1st March, the ceiling fan in the classroom was not working. You can surely imagine the plight of the students already under a lot of stress and tension in the sweltering heat of the sun in the first floor classroom. I am sure that once this problem is brought to your notice the fan in the classroom will be made operational so that the students will not suffer in the heat which will only increase in the days to come. Expecting your kind cooperation in the matter. 

Thanks etc

and the reply was as follows

Dear Sir,
        I am extremely sorry for the inconvenience caused however care is being taken and I ensure that this will  repeated in future.


Thanking you, etc

Now is this just a grammatical error, which considering the  state of English education in India is quite justified, or (horrible to think of) a disguised threat.
The only way to find out will be to wait for the next exam.
