idea about why one should be aware of the history and philosophy of science in order
to lead a scientific life. This chapter also mentions about some discoveries in
science happened in ancient period especially in India and Greece. This chapter
also says about the scientific procedures in a general point of view.
2. Origin of science
enquiry
In
this chapter, the book mentions about the important discoveries that happened
in Palaeolithic age, Neolithic age and Bronze age .Fire pottery was developed
in Palaeolithic age
About 10 000 years ago. In the Neolithic
age, men found agriculture, crop and there happened beginning of cities. In Bronze
Age which began about 400BC they found out metals like copper and bronze, wheeled
vehicles, the sailboat, bricks, Fertilisers etc.
Then they mentions about the discoveries made by man after civilisation. The
discoveries happened in Tigris-Euphrates valley about 7000 years ago are Babylonian
calendar, pyramids in Egypt, in Indus valley they planned and made cities which
include high engineering and architect skills. Since 1600 BC china had horse
drawn chariots time keeping devices abacus and in medical field also they were
well organised.
3. European
origin of science
This chapter give information about the contributions in science from Europe.
It mentions about various philosophers such as Thales, Anaximander, Pythagoras,
Empedocles of Agrigento, Leucippus and their contribution. This chapter also
give idea about Greek medicines. It specially gave a brief note about the
Athens and classic Greece and the world renewed philosophers Plato, Aristotle
and Theophrastus. This chapter also contains a note on the contributions of Romans
in science and mathematics especially the roman number system and Julian calendar.
4.
Contribution of early india
This chapter emphasis on contributions of Indian ancient
textbooks on mathematics and science. It says that arithmetic’s and geometry
was developed in Vedic period and contributions of Aryans to the science. It
mentions about Vedic mathematics, Vedic astronomy and Vedic medicine. It
specially mentions about kanada muni
who said about atoms as the paramanu.
Indians divided substances into nine forms i e , earth, water, fire, air, akasa,
time, space and atman. It also says about the achievements during Buddhist period
where universities like Nalanda and Thakshasila were emerged and scholars
across world came there to discuss about science philosophy mathematics and
geometry. This chapter gives a brief note on Ayurveda and advancement made in India in the field of medicine.
5.Science in
china
Philosophers like Confucius ,Lao Tzu lived in china in the
period 500bc. Chinese made record of all uneven phenomena such as eclipse, appearance
of unknown celestial bodies. The most famous astronomer who lived in china was
Shin Shan (350 BC). He prepared a star chart of 800 charts and gave rules for
predicting eclipse. The astronomical calculations of the Chinese were algebraic
unlike those of Greeks which was geometrical.
China has medicinal treatments like acupuncture, radiant heating, massage,
gymnastics, plasters etc.
6.The role of
the Arabs in the history of science
In this chapter contributions of Arabs
are emphasized. It initially tells about Mohammed prophet and formation of Islam.
Then the chapter discuss about how Palestine and Iraq are formed and how they
invaded Syria and Egypt. The Arab welcomed physicist, chemist, technicians,
physicians etc. Arabs were more anxious to sweep all knowledge into their
empire. The most characteristic Arab scientific development was happened
between 900 AD to 110 AD. Jabir Ibn hayyan was known as the father
of Arab alchemy. The Arab alchemist had performed many practical of chemistry. Abu Ali, Hassan ibn al-haitham
contributed to field of optics. He opposed works of Euclid and Ptolemy. In
mathematic they made significant contribution in the field of algebra. The word
algebra is itself derived from the Arab word Al-jabar . Al-Khwarizmi and his disciple Omar Khayyam made contributions in the
field of mathematics.
Caliph
al Mammon founded an astronomical observatory at Baghdad,
there worked Al Battani in the field
of eclipse, precession of equinox, eccentricity of sun etc. Many observatories were
emerged in Arabs during the period 800-1420 AD. About 800 AD hospitals were
made at Baghdad. Ibn al Nafis who lived in 13th century gave a detailed
idea about circulation of blood.
7.Science in middle ages
This chapter tells about the effect of renaissance and its effect on science.
They understood that in order to increase trade and manufacture, science has to
be developed. Interest in navigation and formation of ships demanded progress
in science thus fluid mechanics was developed. Increased metal usage increased
mining. Leonardo-da-Vinci is an
important figure to be discussed when talking about science in middle ages. He
made plans and design models for flying machines, helicopters, parachutes, guns
etc. He also shows brilliance at anatomical drawings.
This chapter tells about some important revolutions happened in the field of
science. It tells about how the geo centric view of the universe is smashed by
young vibrant physicist such as Copernicus, Tycobrahe, Johannes Kepler etc. This
chapter also tell us about the martyrs of science such as Bruno and Galileo who
suffered a lot because of their contributions to science.
This
chapter also give account on the advancement happened in India during medieval period.
The works of Arayabhata, Madhava, Parameswara
etc in the field of mathematics is world known. Trigonometric functions and
Taylor series was discovered by Madhava in
the period 1340 -1425.
It gave a note on experiments conducted by Gilbert, Bacon.
Works of Descartes about solar systems, coordinate geometry, mathematical
methods in physical science is also mentioned.
8.Newton and after
In this chapter
discussion about scientific enquiries in the 17th century across the
globe is carried out in an elegant manner. Due to the invention of telescope
made by Galileo and invention of microscope much advancement in science is
carried out. Another factor contributed in the enhancement of scientific
discoveries was the establishment of scientific academies.
One sub-unit of this chapter gives a
detailed explanation of life of Sir Isaac Newton. This section mentions about
the important discoveries in science made by Newton such as reflecting
telescope, composite nature of light, laws in mechanics, water cloaks, water
wheels, sundials, working model of wind mills. It also mentioned about the
famous book written by Newton i e the principia
mathematica. This chapter also gave details about persons who were lived in
the time of Newton.
9.The advancing frontiers:
Modern Medicine to Nanotechnology
This chapter tries to discuss about the
advancement made in science in the eighteenth century. It was in the 18th
century the government of many states began to setup public hospitals. While
discussing about advancement in the field of medicine in 18th
century, an important figure is the name of john
hunter who contributed to modernising the surgery, advancement in
dentistry, deep study of inflammation and so on. Other important physicians are
Ignaz Semmelweis, Joseph Lister, Louis Pasteur, his discovery of vaccine,
Robert Koch and his experiment with anthrax bacteria. The advanced technologies
such as MRI, NMR, X-Rays, ECG, EEG made diagnosis of disease quite easy than
before.
In
this chapter other biological topics such as how Linnaeus scientifically
classified plants, Gregory Mendel’s contribution to genetics, Thomas Hunt
Morgan’s experiment with fruit flies.
How James Watson and Francis Crick discovered DNA, The human genome project,
emergence of biotechnology were discussed.
How 18th century scientist contributed about structure of atom was explained in
a good manner. It mentions about Michelson-Morley experiment, Maxwell’s
electromagnetic theory, contributions by Albert Einstein, Contributions of JJ Thomson
, How Rontgen discovered X rays , How Henry Becquerel discovered Radioactivity
, How Marie Curie and Pierre Curie contributed to chemistry by isolating
polonium and Radium, How Rutherford performed experiments with alpha particles
and found out the nucleus, quantum theory of Max Planck , Bohr’s contributions
to structure of atom, how new quantum theory was developed , dual nature of
matter, uncertainty principle , developments in nuclear physics , Developments
of frontier technologies such as Information Technology, Nano-Technology And
Biotechnology , what was the contribution of Homi J Bhaba on cosmic rays and fundamental particles are discussed
in this chapter.
10.Basic concept in the
philosophy of science
This chapter purely explains about scientific methods ie the process involved
in science. It gave a note to distinguish between difference of science and pseudo
science which people get confused in certain times. The methods of induction as
well as deduction are explained and components of science are explained.
11. Some issues in the
philosophy of science
Science gave us more knowledge and due to the
applications of science, i e the technologies, our heavy tasks become much
easier. In this chapter various philosophical dimensions of science is
mentioned. This chapter mentions about mills cannons and criticism of
philosophical approach is done in a good manner. Various controversies about
science and scientific methods are described in a non biased manner.
Reflection
This
book gives us an idea about historical developments of all fields of science in
a highly organized order. In each case, without going into deep analysis of the
situation, the book is written for a general audience. We can suggest this book
to higher secondary students so that they will understand the story behind each
of the topics they study. It helps us to understand the methods involved in
science and it give a positive notion towards research. This book will
encourage people who love science to pursue their dream in science. It s a
worth read book. The language used in this book is simple and people can
maintain the link between various branches of science when reading this book.
