Rocket Ki O Keno? by Sushil Kumar Ghosh [Hardcover]

This book contains no mathematics. It is, in fact, a history of rocket invention. How does a rocket reach its target? What role does it play in space exploration or warfare? This book provides an extensive discussion on these topics.

Kazi Nazrul Islam wrote in his rebellious poem:
"Piercing through the vast cosmos,
Leaving behind the moon, sun, planets, and stars,
Breaking through the earthly and celestial realms,
Crossing the divine throne of God,
I rise as the eternal wonder of the universe’s Creator!"

When this poem was written in the month of Magh in the year 1328 (Bengali calendar), it was purely an imagination. But scientists have turned imagination into reality. Voyager 2 was launched on August 20, 1977; it reached Jupiter in 1979 and came into Saturn’s sight in 1981. It reached Uranus in 1986, and Uranus’ gravity pulled it toward Neptune. After completing its journey past Neptune, Voyager 2 continues its voyage towards Pluto at an incredible speed of 67,000 kilometers per hour.

In space, there is no air resistance, no fuel costs—no petrol, no steam, no liquid hydrogen, no liquid oxygen, no hydrazine, no kerosene, no fuming red nitric acid. According to the law of inertia, it is racing towards Pluto at this tremendous speed.

This book, written in a simple and engaging style for curious readers, offers a detailed introduction to the wonders of modern space exploration and the incredible spacecraft that science has created.
