Acharya Kanad (600 BCE)

He was the pioneer expounder of realism, law of causation and the atomic theory.

He classified all the objects of creation into nine elements : earth, water, light, wind, ether, time, space, mind and soul.Þi`fFkO;kiLrstksÞi`fFkO;kiLrstksÞi`fFkO;kiLrstksÞi`fFkO;kiLrstks ok;qjkdkok;qjkdkok;qjkdkok;qjkdk’’’’kakakaka dkyksfnXkRokeudkyksfnXkRokeudkyksfnXkRokeudkyksfnXkRokeu bfrbfrbfrbfr ææææO;kf.kO;kf.kO;kf.kO;kf.kßßßß

He said, "Every object of creation is made of atoms which in turn connect with each other to form molecules." 2500 years before John Dalton.

He further saidßæ"Vkuka] æ"VÁ;kstukuka] æ"VkHkkos Á;ksxks vH;qn;k;Þ

FOUNDER OF ATOMIC THEORY, believed to have been born in Prabhas Kshetra near Dwarika in Gujarat, he propounded "Vaisheshik Darshan"- one of six principal philosophies of India

Kanad also described the dimension and motion of atoms and their chemical reactions with each other.

Seen by self, Shown to the others, and through the experiments, done to know more details, lead the path to the Development.

ACHARYA SUSHRUT (600 BCE)

He is venerated as the father of plastic surgery and the science of anesthesia. When surgery was in its infancy in Europe, Sushrut was performing Rhinoplasty(restoration of a damaged nose) and other challenging operations.

He prescribes treatment for twelve types of fractures & six types of dislocations, and his details on human embryology are simply amazing.

Sushrut used 125 types of surgical instrumentsincluding scalpels, lancets, needles, Catheters and rectal speculums. He has also described a number of stitching methods; the use of horse's hair & fibers of bark as thread .

"Sushrut Samhita," details 300 types of operations. The ancient Indians were the pioneers in amputation, caesarian and cranial surgeries.

A master surgeon, Sushrut details first ever surgery procedures in "Sushrut Samhita," a unique encyclopedia of surgery.

ARYABHATT, Astronomer & MathematicianBorn in 476 CE in Kusumpur (Bihar), He remapped the boundaries of mathematics and astronomy.

In 499 CE, He wrote "Aryabhatiyam"Formulated the process of calculating the motion of planets and the time of eclipses.

First to proclaim “The earth is round, it rotates on its axis, orbits the sun and is suspended in space”1000 years before Copernicus published his heliocentric theory. He is also acknowledged for calculating p (Pi) to four decimal places: 3.1416 and the sine table in trigonometry. Most spectacular contribution was the concept of zero without which modern development in science & Technology was not possible

NAGARJUNA (100 CE) WIZARD OF CHEMICAL SCIENCE & Metallurgy

"Ras Ratnakar, Ras Hrudaya" and "Rasendra mangal" are his renowned contributions to the chemistry.

As the author of medical books like "Arogyamanjari" and "Yogasar," he also made significant contributions to the field of curative medicine.

Indians knew of extraction of Iron,GoldSilver,Zinc,Lead,Mercury & Copper from the ores and also mastered technique of making different Alloys from these Metals such as Non rust Steel,Brass, Bronze etc

gold (Au), silver (Ag), copper (Cu), iron (Fe) and lead (Pb)

Panchloha

His discoveries and inventions in chemistry &metallurgy were phenomenal.

Clay Retort

Ref. Rasaratna samucchaya

Metallurgy – eco friendly Zawar process for Zinc (500 BC)

The furnace has two chambers. One with inverted retorts

another with condensing vessels under each retort.

Retort is filled with calcined

ore, charcoal,salt etc. A reed is

set in the middle and a funnel like condenser fitted at the end and sealed with the vessel.

Retort is heated to 1200oC. to vaporise

zinc. At this temperature reed gets burnt and other materials release CO to create

reducing atmosphere. Zinc trickles down through a path created by burnt reed.

Historian Vincent Smith writes

“While we marveled at the skill shown by ancient artificers in forging the great mass of Delhi pillar, we must give a still greater measure of admiration to the forgotten craftsmen, who dealt so successfully in producing the still more ponderous iron mass of the Dhar pillar monument”.

14 meters in height and 7 MT in weight (3 pieces together), built by Bhojin (1000-1055AD) “is a largest

non corrosive Iron Pillar in the world”

Bhāskara-I (600-680 CE)A Poet, Astronomer & Mathematician

First to write numbers in the Hindu-Arabic decimal system with a circle for zero, and gave a unique and remarkably rational approximation of the sine function in his commentary on Aryabhata's work Āryabhaṭīya bhāṣya,in 629 CE, also wrote Mahā bhāskarīyaand the Laghu bhāskarīya.

implies that the ratio of the circumference to the diameter is ((4 + 100) × 8 + 62000)/20000 = 62832/20000 = 3.1416

Page 12: Science past present & future

Bhaskaracharya II (1114-1183 CE)

In his treatise "Siddhant Shiromani" he writes on planetary positions, eclipses, cosmography, mathematical techniques and astronomical equipment.

In the "Surya Siddhant" he makes a note on the force of gravity: "Objects fall on earth due to a force of attraction by the earth. Therefore, the earth, planets, constellations, moon, and sun are held in orbit due to this attraction." 500 years before Newton.

GENIUS IN ALGEBRA Born in Vijjadit (Jalgaon) in Maharastra, his texts in Algebra, Arithmetic & Geometry, "Lilavati" and "Bijaganita" got translated in several languages of the world

Also wrote texts on “Grahaganita” and “Goladhyaya”

Whatever I learnt from experts and whatever I confirmed by experimentation, onlythat, I have included in this book and whatever could not be confirmed has notbeen included in my book.

Further, he states that my student should reconfirm by performing experiment bytheir own hands. Those who follow this is a true teacher and student. All others are just Drama Actors.

Vasco da Gama, as per his diary kept in Spanish Museum, in 1497,saw a three times bigger ship in Jhanjibar and met its Gujarati owner named “Skanda” with who’s help He came to India

In 1811, Lt. Walker writes that East India company had an Indian ship “Daria Daulat”which did not require maintenance for 87 years He further proved statistically, the Indian ships were much cheaper & better in quality than English ships and advised East India Company to use Indian ships only

Indian Trade & Shipping

1814 - British Government passed an act to ban Indian ships and Indian sailors from visiting British Ports1863- Act was strictly implemented and heavy taxes were levied on the goods from Indian Ships to bring about the end the Indian Ship Industry.

Sriniwas Ramanujan (1887-1920)�With no formal training in pure mathematics, made extraordinary contributions to Mathematical Analysis, , Number theory, infinite series & Continued Fractions

�By age of 12, mastered Trigonometry by S.L. Loney;

� Discovered new theorems and independently re-discovered Euler's identity, Bernoulli numbers and the Euler–Mascheroni constant.

G.H. Hardy, recognizing his work, invited Ramanujan to visit & work at Cambridge. He Was awarded a B.A. degree by research (this degree was later renamed PhD) in March 1916 for his work on highly composite numbers,He became a Fellow of the Royal Society and a Fellow of Trinity College for his investigation in Elliptic functions & the Theory of Numbers." By 13 October 1918 Ramanujan independently compiled nearly 3900 results (mostly identities and equations) which inspired a vast amount of further research
