John Tyndall (scientist)

John Tyndall was a 19th-century English scientist who made significant contributions to understanding heat, light, and gases. He studied how infrared radiation relates to the Earth's atmosphere and demonstrated that greenhouse gases like carbon dioxide and water vapor trap heat, influencing climate. Tyndall also researched the scattering of light, explaining why the sky is blue, and developed methods to detect small quantities of gases. His work helped establish basic principles of atmospheric science and environmental physics, laying groundwork for modern climate science and our understanding of Earth's climate system.
