When it comes to the nature of light, Renée Descartes’s wave idea had considerable merit. He believed that a substance called aether permeated the universe through which light was conducted like a wave. […]
French physicist Louis de Broglie was the first to propose that like photons, electrons, too, could be both waves and particles. Later, the Davisson-Germer experiment proved him to be correct. […]
Einstein hypothesized that a beam of light was actually light photons. He published it in his paper referring to it as the photoelectric effect. […]
Thomas Young’s double slit experiments showed light exhibiting exactly the same phenomenon as the interference of water waves. Using lasers he observed many beams of light coming through the slits, proving that light was a wave. […]
The modern world gets plenty wrong about science. From the myth of Benjamin Franklin’s kite to misunderstanding evolution, incorrect information abounds. Is it possible to travel faster than the speed of light? […]
Was the Big Bang really the beginning of time? The world-renowned periodical has published scientific reading material for nearly 180 years. In a new series, Wondrium and Scientific American answer the big questions of time. […]
The famous “Schrödinger’s cat” is more than a joke about the unknown. It’s a hypothetical way of understanding an idea in quantum mechanics known as superposition. This week on Wondrium, philosophy meets physics. […]
The Big Bang has technically been ongoing for nearly 14 billion years. As the universe continues to expand, the explosion that started it is still ringing out. The study of its earliest known moments, its first few minutes, continues to be examined. […]
The Big Bang is a popular but misunderstood scientific theory. For example, many people think the Big Bang was a one-time event, but it continues today. This week on Wondrium Shorts, discover the Big Bang’s presence all around us. […]
One problem regarding the research on the cosmic microwave background is the noise and interference emitting from various sources on Earth. The solution is to use space-based telescopes. […]
