Give some reasons why our knowledge of physical science has increased considerably in the past few years.?

Question

It's for our recitation tomorrow, the more answers I get, the better. Thanks.

Answer 1

Science is cumulative. Newton said, "If I have seen further it is by standing on ye shoulders of giants"

New and improved technology lets us do more and better observations and experiments. Much of that is fueled by new science.

Industrialization has so improved our productivity that mankind no longer needs to devote all its efforts to survival. I wish we made better use of that luxury. Some societies choose to invest in science for the long-term benefit of man, even if the benefit is not immediate.

Libraries, electronic publishing, the Internet, search engines, and email have greatly improved communication for scientific endeavors and results. This helps qualified individuals educate themselves, despite poor public education.

If you use some of my thoughts in your recitation, please cite me as a reference. Thanks in advance for your intellectual honesty.

Answer 2

When people started to believe that philosophy is not the real base for science. Scientists started to depend more and more on mathematics and experiments rather than the prior judgment. The two great theories (Relativity and Quantum Electrodynamics) pushed the science to news limits that lead to most of our technological achievements today. Because they didn't depend on any prior judgments, they established the new way of thinking that lead to technology revolution we have now.

Answer 3

New instruments allow scientists to see thing never before seen.
The electron microscope allows atoms to be seen.
The Hubble telescope peers farther into the sky.
Magnetic Resonance gives a better picture to doctors than xrays.
And so on.

Answer 4

more people have entered into the field to study it
