🔬 Key Scientists and Their Contributions
1. Isaac Newton
He is known as the father of modern physics. His laws of motion and universal gravitation changed the way humans understood the universe. Newton also contributed to mathematics by developing calculus. His work laid the foundation for many future scientific discoveries.
2. Albert Einstein
Einstein revolutionised science with his theory of relativity. His famous equation E = mc² changed our understanding of space, time, and energy. He also played an important role in quantum theory. Einstein is considered one of the greatest minds of all time.
3. Charles Darwin
Darwin introduced the theory of evolution through natural selection. His book On the Origin of Species completely changed the field of biology. He explained how life on earth evolved over millions of years.
4. Nikola Tesla
Tesla made major contributions to electrical engineering. His work on alternating current (AC) power system helped bring electricity to homes and industries around the world. Tesla was a visionary thinker with ideas far ahead of his time.
5. Marie Curie
She was the first woman to win a Nobel Prize and the only person to win in two different scientific fields — physics and chemistry. Curie discovered the elements polonium and radium, and her research helped in the development of cancer treatments.
6. Galileo Galilei
Known as the “father of modern science”, Galileo made important discoveries in astronomy, physics, and mathematics. He improved the telescope and proved that Earth moves around the sun.
7. Louis Pasteur
Pasteur’s research in microbiology saved millions of lives. He developed the process of pasteurisation and created vaccines for diseases like rabies and anthrax. His work changed the medical field forever.
8. Stephen Hawking
Hawking contributed greatly to the understanding of black holes and cosmology. His book A Brief History of Time made complex scientific ideas easy to understand for common readers.
9. Gregor Mendel
Mendel is called the father of genetics. His experiments with pea plants explained how traits are passed from parents to children. His work laid the foundation of modern genetics.
10. Thomas Edison
Edison invented the electric bulb, the phonograph, and many other devices. His innovations brought technology into everyday life. Edison holds more than 1,000 patents.
These are only a few names from the list of 100 scientists. The book covers many more important figures like Aristotle, James Clerk Maxwell, Alan Turing, Carl Linnaeus, Jane Goodall, Rachel Carson, and many others.
