Famous Personalities and Discoveries

Charles Lyell propounded the principles of geology explaining the various geological changes on the Earth's surface.

Statement 1 is correct. Nicolaus Copernicus is known as the father of modern astronomy. Statement 2 is incorrect. Galileo Galilee was the first who used the telescope to make detailed studies of heavenly bodies.

This is the correct option. Gregor Johann Mendel is known as the Father of Genetics.

The DNA profiling technique was first reported in 1984 by Sir Alec Jeffreys at the University of Leicester in England, and is now the basis of several national DNA databases.

Yes, it is the correct answer. He arranged three elements in one group which is known as ‘triad’. Such arrangements of elements are known as Dobereiner’s triads.

He is father of modern genetics.

Hugo Grotius was a towering figure in philosophy, political theory, law and associated fields during the 17^th century and for hundreds of years afterwards. His work ranged over a wide array of topics, though he is best known to philosophers today for his contributions to the natural law theories of normativity.

Paul Ehrlich is called 'The Father of Chemotherapy'.

Sir Henry Dunant, in 1864, founded the Red cross.

The first pendulum clock was invented by Christiaan Huygens in 1656.

Aryabhata, the renowned Indian astronomer and mathematician (476-550 AD), proposed that Earth rotates on its axis and that bodies gravitate toward Earth. In his work 'Aryabhatiya,' he discussed the concept of gravity centuries before Newton. Brahmagupta later formalized gravitational theory more explicitly in the 7th century.

Dmitri Ivanovich Mendeleev developed the Periodic Law in 1869, arranging elements by atomic weight and predicting undiscovered elements. Niels Bohr developed atomic structure theory, Huygens studied wave optics, and Newton formulated classical mechanics.

It is the correct answer. Thomas Robert Malthus was the first economist to propose a systematic theory of population.

Dmitri Ivanovich Mendeleev is credited with developing the Periodic Law in 1869, which states that chemical properties of elements are a periodic function of their atomic masses. He created the first periodic table and even predicted the existence and properties of elements that had not yet been discovered. Niels Bohr developed atomic structure theory, Huygens studied wave optics, and Newton formulated classical mechanics.

Albert Einstein, a German mathematical physicist, developed the theory of relativity (both special and general). Newton formulated classical mechanics, Planck founded quantum theory, and Galileo pioneered physics and astronomy.
