Hi Everyone!! This article will share Is Science Useful Questions & Answers.
In my previous posts, I have shared the questions and answers of The Day of An American Journalist in 2889, Sound Sensations From Evelyn Glennie and Adventures In Antarctica so, you can check these posts as well.
Is Science Useful Questions & Answers
Question 1: What is the question that scientists and researchers are repeatedly asked?
Answer: Scientists and researchers are repeatedly asked regarding the practical application of their findings.
Question 2: What use do the theorems taught by the ancient Greeks have?
Answer: The theorems formulated and taught by the ancient Greeks formed the basics for further scientific enquiry as the world progressed. Several of the mathematical theorems of the time are conditionally put into use. For example – in the planning and development of modern telephone networks.
Question 3: Was the principle demonstrated by Faraday found to have any use? If yes, what was it?
Answer: Yes, the principle demonstrated by Faraday did find use. It is the basic principle used to produce electricity on a mass scale in every kind of power plant from hydroelectric to thermal.
Question 4: Why did Edison not consider the strange effect that he noticed to be significant?
Answer: Edison observed that electricity flowed from the bulb’s filament to the wire in a vacuum. However, he did not think it significant as he did not understand the principle behind it.
Question 5: How was Edison proved wrong in this matter?
Answer: Edison was proved wrong in this matter because as this phenomenon was later studied by other scientists and one of them invented the radio tube that now has made all our modern electrical equipment possible.
Question 6: The work of the physicists of the 1930s and 40s were put to good and bad use. Give one example for each.
Answer: Physicists of the 1930s and 40s found that massive amount of energy could be released in nuclear fission and fusion that could destroy mankind in a day. This discovery led to the development of nuclear bombs.
However, on the brighter side, researchers also came up with radio isotopes which are used in medicines in a thousand ways.
Question 7: Complete the following notes on the basis of the text.
(a) Scientists and philosophers asked about the practical use of their findings.
Answer:
- Find learning, understanding and probing the universe to be its own reward.
- Know that new findings, despite being insignificant in terms of practical utility, leads to further the finding and understanding that could revolutionize the world.
(b) Practical value not always predictable.
Answer: While Edison was shrewd in finding the practical application of scientific principles, he didn’t understand or place value in the finding that electricity passed from filament to wire in a vacuum. This principle was later used to develop many technologies.
(c) Abstract finding later find important uses.
Answer:
i. Edison effect used in current rectifier and television.
ii. Einstein’s E = mc2 used in nuclear power.
(d) Applications of science may have negative effects:
Answer: The development of nuclear bombs.
(e) The way forward.
Answer: Advancing knowledge will improve the material lot of man but needs to be guided by the wisdom of man.
