Physical World

The complexity content of this world is very high. Almost everything in this world is equated in terms of mass, time and length. In spite of all this, all the physical phenomena can be explained with very few basic principles of Physics. So basically, Einstein meant to say that despite such complexities, it is possible to simplify the world with some basic laws of Physics.

There are two sides of Physics, one which is orthodox and goes by convention like for example negative or positive signs assigned to the values and the other, which is the one which does not follow conventions. Now, the opinions which are against the conventions are called HERESY, while an established stuff is known as DOGMA. For example, Copernicus’s geocentric theory was a heresy, until it was proved and became a Dogma.

Politics is a dirty game. You play in a dirty game, sweep it under the carpet, no one notices it and you remain in power. That is what the politicians do, they try to remain in power by any illegal or foul methods and never follow the norms. Meanwhile, a scientist gives times to phenomena, observes it carefully study it, explain it to the whole world and after a discovery is confirmed they present it to the whole world for its own good sake. This is why “Politics is the art of possible” and “Science is the art of soluble”.

Factors which have hindered the advancement of science in India are as follows:-

1. Lack of clear-cut policies at the political level. Undue political interference and bureaucratization in the management of science and technology.

2. Due to excessive population, our country cannot afford to expend sufficient funds on science and technology.

3. Gifted scientists and researchers are not given proper exposure. They should be encouraged to do more of research work from a little age.

4. There is lack of coordination between researchers and

industrialists. Industrialists like to borrow technology from advanced countries rather than to use indigenous technology.

Theorems existing in this world are all based on the fact that electrons do exist in atoms. If the concept of the electron is removed from proven Physics, then there will be a crisis of arguments in the existing theories and anything won’t be enough to correctly explain the theories. Whereas, removing ghosts from the world won’t affect any of the existing concepts.

Option B is the best explanation.

B. After the sea tragedy, fishermen in that area, in a gesture of honor to their dead hero, let free any crab shell caught by them which accidentally had a shape resembling the face of a Samurai. Consequently, the particular shape of the crab shell survived longer and therefore in course of time the shape was genetically propagated. This is an example of evolution by artificial selection.

Explanation: Nature won’t give tribute to anyone. It is governed by the laws of physics. But, there is a chance of formation of samurai's face accidentally by means of probability.

The industrial revolution starts in England and Western Europe in mid-18^th Century. Its main contributions are inventions to perform work in effective and efficient manner. Some of them are,

1. Blast Furnace

It is the closed type of furnace which is capable of generating high temperatures. It is used to convert Iron into steel which is most widely used element nowadays.

2. Cotton Jenney

It is said to be a most valuable invention in the 18^th century because it reduces time to collect cotton from cotton flowers. It is almost 300 times efficient than a normal hand.

3. Steam engine

Steam engine invented by James Watt. It revolutionizes the transport system which ultimately leads to connectivity between countries. So, different peoples, cultures and their ideas mingle to form revolutionary products and inventions to the modern world.

There are many other inventions that are outcomes of the industrial revolution which pave the path for modern technology.

The major areas which will lead to second Industrial revolution in future are,

1. Internet and its availability to users

2. Development of supercomputers

3. Development of superconductors

4. Artificial Intelligence and machine learning

5. Exploration of universe

6. DNA as a source of data storage, etc.

Let me take into the year A.D 2125. Human colonies are developed on mars and moon. One day evening a mysterious asteroid driven by aliens coming towards our colonies, then International Space Soldiers Army (ISSA) which is developed by all the nations have come into the picture. They pointed a multi satellite-based Laser gun (MSLG) towards it and destroyed the asteroid. This MSLG is working with the radiation coming from the sun, it has debris collector inbuilt and it requires no other source of energy.

There are still so many hidden secrets in the universe. A discovery or invention cannot be hidden under the mask because man seeks progress. His enthusiasm leads to discoveries and inventions. It’s me or other, whoever may be every governing law of nature will be revealed. As a coin has two sides, knowledge too. It helps in the understanding of nature but also may cause harm. A wise knowledgeable person never hesitates to reveal his work to society.

But, the one who is using that knowledge have two options,

CONSTRUCTION or DESTRUCTION it depends one's perspective thinking and wisdom.

A. The small pox virus kills so many human beings and survivors have permanent effects. Thus, the mass vaccination against smallpox is good for society.

B. Television for the eradication of literacy and for mass communication of news and ideas is good.

C. Parental sex determination is considered to be bad because it leads to gender imbalance and it is banned legally in many countries.

D. Computers are helpful to do a work in an efficient manner and in an effective way. It results in globalization and increases connectivity between people around the world. Thus, Computers are considered to be good.

E. Launching of artificial satellites is good because the internet, television, a Global positioning system (GPS) and many other bridges between human across the great seas are based on this artificial satellite.

F. Even though Development of nuclear physics leads to effective generations of electricity it is considered to be bad. Because, it gives rise to the destruction of human colonies during wars, insert permanent changes to genes of living beings and cause environmental changes.

G. Development of new and powerful techniques of chemical and biological warfare is bad. It can be simply misused by terrorists, anti-government societies, etc.

H. Purification of Drinking water is good. It is the main problem that we are facing nowadays.

I. Plastic surgery is considered to be good. Because, it gives new life to victims of acid drop, fire accidents, and many others.

J. Cloning is cannot be categorized. Because, reproduction of new organs using cloning is good but, production of whole human being leads to so many social and security problems.

First and foremost, step would be to educate the people and spread the literacy. The people must be taught about the science behind the natural phenomenon occurring in nature day-to-day life and superstitious beliefs, these phenomena which people attribute to evil spirits and gods should be explained scientifically through mass media such as television, newspapers, cinema, etc. we also should not take these superstitions for granted and follow them. Instead, we should do otherwise. We should also tell and try to convince other people to not to believe or follow the superstitions unless they are scientifically proven. We should investigate these superstitions to its roots, if possible.

The names of Madame Curie the Nobel laureate, Indira Gandhi, Margaret Thatcher, Mother Teresa, Kalpana Chawla, from various fields varying from science to sociology is very well-known to the world, and at times these need to be reminded of the people who hold unscientific views on a woman’s innate nature, capacity and intelligence, and in practice give them a secondary status and role. By nature, there exists some difference in man and woman biologically, but that doesn’t make women any inferior to men.

An equation strikes to someone as beautiful if it’s essence is understood to him/her. Some of the beautiful equations from this book are Newton’s 2^nd Law of motion (i.e. F = ma), Einstein’s Equation for mass-energy relation (E = mc²).There are some equations of Quantum Mechanics and Theory of Relativity are highly cumbersome and difficult to understand, yet they agree with the experiments.

Books on General Physics are interesting, like ‘Surely you are joking, Mr. Feynman’ by Richard Feynman is one of the books. Interested students should consult their teachers and should go to the library and search these books. Students can search for these books on the internet as well.

Scientists, like any other group of humans, have their share of humourists, and many have led their lives with a great sense of fun and adventure, even as they seriously pursued their scientific work. We can take the example of many scientists like Albert Einstein, Richard Feynman. C.V. Raman, etc., who were fun, adventurists and loving. Albert Einstein played the violin and enjoyed Mozart’s music, Richard Feynman the greatest explainer ever was humours and he played the bongo in addition to doing the serious scientific work.
