Description:
In 2002, Professor Robert Crease, a philosopher and historian of science, asked physicists to nominate the most beautiful experiment of all time. From that emerged a list of ten most beautiful experiments in science. In this book I have tried to describe the physics of the ten experiments with the hope that young students will be able to appreciate the beauty and profoundness of each experiment. I have also discussed a few beautiful experiments with light and why (after the discovery of lasers) the study of light has become so very important. I do hope that by reading this little book, young students will try out a few experiments in their school and aspire to learn more of basic physics.
Target Audience:
Useful for students of class 11 & 12 and also for undergraduate students studying physics.

Preface
1. Introduction
2. The Ten Most Beautiful Experiments in Science
Experiment 10: The experiment involving Foucault’s pendulum demonstrating the rotational motion of the Earth (1851)
Experiment 9: By studying the scattering of alpha particles by thin films of gold, Ernest Rutherford discovered that most of the mass of the atom is concentrated in a tiny region known as the nucleus; thus he discovered the atomic nucleus (1911)
Experiment 8: Galileo’s experiments (around 1604) showing that the distance traversed by objects sliding down inclined planes is proportional to the square of the time of descent
Experiment 7: Eratosthenes’ measurement of the Earth’s circumference (Around 3rd century BC)
Experiment 6: Cavendish’s torsion-bar experiment which determined the Gravitational constant G and “weighed the world” (1798)
Experiment 5: Young’s interference experiment demonstrating that light was a wave (1801)
Experiment 4: Isaac Newton showed that a narrow beam of sunlight falling on a glass prism gets dispersed into various colors (mid 17th century)
Experiment 3: Millikan’s oil-drop experiment measuring the charge of the electron (1911)
Experiment 2: Galileo’s experiment on falling objects; that if two objects of much different weights are dropped from a height, both take the same amount of time to reach the ground (late 16th century)
Experiment 1: Double slit interference experiment with single electrons which demonstrated the quantum interference of single electrons and therefore quantum nature of the physical world (mid 20th century)
3. Why Study of Light Has Become So Important?
The Laser
Fiber Optics: Total Internal Reflection and Scattering
LIGO (The Laser Interferometer Gravitational-Wave Observatory)
