What is giftedness?

Let’s pick up a Science textbook – Physics, Chemistry, Biology

Each book 1000 pages x 30 sentences = 30000 lines of knowledge

How many of these knowledge sentences are created by Indian scientists?

What is the cultural set up in which we impart education?

Science Technology Comfort

Galileo

Newton

Einstein

Science as intellectual pursuit

Cogito ergo sum Rene Descartes (1596 – 1650)

I THINK, THEREFORE, I AM

𝐹 = 𝐺𝑀1𝑀2

Why does this equation explain one aspect of physical universe?

Why does this equation explain one aspect of physical universe?

- The universe was created at one point of time – law must appear after that

- The brain that constructs this law has only evolved this ability recently

- The symbols and mathematics that express it is also recent

IS this equation really THE explanation of THIS aspect of physical universe?
