Question

Speech on elderly inventors and inventions

Answer 1

Have you ever dreamed of becoming a great inventor—of having a fantastically clever idea that changes society for the better and makes you rich in the process? The history of technology is, in many ways, a story of great inventors and their brilliant inventions. Think of Thomas Edison and the light bulb, Henry Ford and the mass-produced car, or, more recently, Tim Berners-Lee and the World Wide Web. Inventing isn't just about coming up with a great idea; that's the easy part! There's also the matter of turning an idea into a product that sells enough to recoup the cost of putting it on the market. And there's the ever-present problem of stopping other people from copying and profiting from your ideas. Inventing is a difficult and often exhausting life; many inventors have died penniless and disappointed after struggling for decades with ideas they couldn't make work. Today, many lone inventors find they can no longer compete and most inventions are now developed by giant, powerful corporations. So, are inventors in danger of going extinct? Or will society always have a place for brave new ideas and stunning new inventions? Let's take a closer look and find out!

Answer 2

Hello friends, I speek now on a topic of tremendous interest to science lovers. 

Introduction:
Invention is the activity of investigating
and finding a new method of achieving  something, or making a new device, or formulating a new principle or concept or law that governs us or nature.   (Discovery finds something which is already there, but we have not known about it.)

Let us take some names now:
Great scientists like Newtons, Edison,
Chandra Shekhar,  JC Bose, CV Raman, Eintstein, Archmedis, Pascal,
Bernouli, Arya Bhatta, Curie, B Gates, Thomson are all great inventors. The invention of semiconductor transistor device
by Bardeen and Brattain and William Schockley has lead to the most
sophisticated computers, laptops, cell phones, calculators etc.  Every electronically controlled device makes use of their inventions.The invention of USB by Ajay Bhatt has allowed use of many devices with computer.  Their lives inspire us to strive to achive a similar glory.
Let us know what is needed to be inventive:
One needs to be creative, objective, have analytical capacity, mathematically good,
ability to correct own faults, and to work alone. Excellent abilities to visualize and imagination are needed.   We take the challenge in front of us to find solutions, in favorable or unfavorable situations.

Inventors
dedicated their lives to their field and to the good of mankind. Many of them
sacrificed their personal life and made our life on Earth today comfortable.  It was not easy for them. But inventors make a lot of money and become world famous.  ( Alfred Nobel made a lot of money and the prize money comes from the interest on that.)
 
Conclusion:
Let us all work systematically to invent, and encourage inventors.  Let us make our life better tomorrow.
