Question

The idea of parmanu was given by :
A. MAHARISHI KANAD
B. DEMOCRITIOUS
C. DALTON
D. WILLIAM CROOKES

Answer 1

Hint:-parmanu in English is called an atom. An English chemist and physicist, is the man credited today with the development of atomic theory named John Dalton (1766 – 1844) but , A theory of parmanu was formulated by Acharya Kanad an Indian sage and philosopher, 2,500 years before Dalton theory.

Complete step-by-step solution:
Recently Maharaja Sayajirao University made some claims in its official diary hailing some ancient Indian sages Acharya Kanad
Acharya Kanad’s name became associated with nuclear technology. Acharya Kanad is the founder of the system of philosophy (Darshan) called Vaisheshik that propounds the doctrine of parmanu (atoms) as part of its metaphysics. The doctrine of discovery of parmanu is somehow considered equivalent to the modern atomic theory of science.
The doctrine also makes it very clear that these atoms are not perceivable but are to be inferred, although the principle of inference is not clear. As a result, it would be more appropriate to say that it’s not inference that plays any part here but some kind of speculation.
Then people started calling him Kanad. The term KAN in Sanskrit means “Smallest particle“.
So Sage acharya Kanad formulated ideas about the atom in a systematic manner he lived in the 6th century B.C.

Note:-
Dalton’s atomic theory
The same element atoms are similar in shape and mass, but differ from the atoms of other elements.
All matter consists of indivisible particles called atoms
Atoms cannot be created or destroyed.
different element atoms may combine with each other in fixed, simple, whole number ratios to form compound atoms.
