speech on science and its inventions
Answers
Explanation:
As we look back in our ancient times we see so much development in the world. The world is full of gadgets and machinery. Machinery does everything in our surroundings. How did it get possible? How did we become so modern? It was all possible with the help of science. Science has played a major role in the development of our society. Furthermore, Science has made our lives easier and carefree.
I have mentioned earlier Science has got many changes in our lives. First of all, transportation is easier now. With the help of Science it now easier to travel long distances. Moreover, the time of traveling is also reduced. Various high-speed vehicles are available these days. These vehicles have totally changed. The phase of our society. Science upgraded steam engines to electric engines. In earlier times people were traveling with cycles. But now everybody travels on motorcycles and cars. This saves time and effort. And this is all possible with the help of Science.
Secondly, Science made us reach to the moon. But we never stopped there. It also gave us a glance at Mars. This is one of the greatest achievements. This was only possible with Science. These days Scientists make many satellites. Because of which we are using high-speed Internet. These satellites revolve around the earth every day and night. Even without making us aware of it.
Science is the backbone of our society. Science gave us so much in our present time. Due to this, the teacher in our schools teaches Science from an early age.
Answer:
While history is full of stories of famous inventors, who are often national heroes, in almost every case they were just the first people to improve an existing system to the final stage where it achieved mass appeal.
Think of how scientific discoveries from hundreds of years ago inspired the works of subsequent generations of scientists.
Or how the iPod revolutionised personal music thanks to the combination of progress in the disparate fields of digital music compression, hard drive miniaturisation, cheap ARM microprocessors and various other technological innovations.
1. While Galileo is often credited with devising the first telescopes, there was actually a Dutch man called Hans Lippershay who had been making magnification devices using the ever improving qualities of glassmaking at the time.
2. James Watt and the steam engine
When I was in high school, my science teacher thought it was funny to ask “What was the name of the man who invented the steam engine?” Hilarious, because “Watt” was the answer, so the question was also a statement.
3. Eli Whitney and the cotton gin
During times of slavery in the USA, Georgia predominantly grew cotton which had shorter fibres. This didn’t work well with the machines at the time which tried to remove seeds from the fibres (roller gins), and required a lot of manual work. So the state of Georgia sponsored an engineering push to come up with a better design.
