India was home to many important scientific and mathematical firsts according to the document. Baudhayana first calculated pi and discovered the Pythagorean theorem centuries before Pythagoras. Aryabhatta introduced the concept of zero, calculated the distance to the moon, and proposed that the earth rotates daily and is round. Bhaskara introduced algebraic equations and stated the law of gravity. Kanad developed an atomic theory comparable to modern theories. Varahmihira theorized about earthquakes and Pingala described binary numbers and the Fibonacci sequence. Susruta and Charak laid the foundations of surgery and Ayurvedic medicine respectively in ancient texts still used today.

1. INDIA THE
LAND OF MANY
FIRSTS

2. BAUDHAYANA:
 The value of pi was first
calculated by
baudhayana
 What is known as
pythagoras theorem
today is already found in
baudhayana’s “sulva
sutra”,before the age of
pythagoras.
.

3.  Aryabhatta showed that
zero was not a numeral
only but also a symbol
and a concept.
 Aryabhatta find out the
exact distance between
the earth and the moon.
 Aryabhatta stated his
theory that ‘earth is
round and rotates on its
own axis’ He explained
that the appearance of
the sun moving from east
to west .

4.  He introduced
negative numbers
and operations on
zero into
mathematics.
 He wrote Brahm
Sputa Siddantika
through which the
Arabs came to know
our mathematical
system

5. Bhaskaracharya:
 Bhaskara introduced
 Chakrawat Method or the Cyclic Method
to solve algebraic equations.
 He is famous for his book SIDDANTHA
SIROMANI
 The first principle of gravity was stated by
“Bhaskaracharya” and “not Newton”
 Bhaskaracharya stated the laws of gravity in the book
Surya Siddhanta in 11th century.

6. • Jain Guru Mahaviracharya wrote
 Ganit Sara Sangraha
in 850A.D., which is the first
textbook on arithmetic in
present day form
 The current method of solving Least
common Multiple (LCM) of given
numbers was also described by him.

7. Kanad:
• He got the name kanad
,because
• he was interested in minute
particles called “kana”.
• His atomic theory can be a
match to any modern atomic
theory.

8.  He was one of the first
scientists to claim that
termites and plants
could be the indicators
of the presence of
underground water.
 Another theory
earthquake cloud
theory given by
Varahmihira in his
Brhat Samhita.

9. Susruta:• Susruta the
• father of surgery.
• In Susruta Samhita, the method of
selecting and preserving a dead
body for the purpose of its detailed
study has also been described.

10. Charak is called
the father of ayurvedicmedicine.
His Charak Samhita is a
remarkable book on
medicine.
Don’t you find it fascinating
that thousands of years
back, medical science
was at such an advanced
stage in India.

CHARAK:

11. JAGDISH CHANDRA
BOSE:
the development of wireless telegraphy.
The first public demonstration of radio waves for
communication was made by Sir Jagdish Chandra Bose
in 1895,

12. Pingala:
 Binary numbers were first
described by Pingala (c. 200
BC).
 the earliest known Sanskrit
treatise on prosody.
 He also invented
the Fibonacci
sequence

13.  4. Ruler
 Rulers were first used by the Indus Valley
Civilization prior to 1500 BCE. Made of ivory, the rulers found during
excavation, reveal the amazing accuracy of decimal subdivisions on it

14. 3.WATER ON MOON
 ISRO’s Chandrayaan-1 made
the startling discovery that
our moon is not a dry ball of
rocks
 The discovery of lunar water is
attributed to the
Chandrayaan
mission.

15. FLUSH TOILETS:
Flush toilets were first used in the Indus Valley
Civilization. These existed in most homes and were
connected to a sophisticated sewage mechanism. The
civilization was prominent in hydraulic engineering.

16. So, we’ve always been a cool country. History is
testimony to it. So what’s stopping you from being innovative? Go, win the
world.
