Planck's Length is the length below which the concept of length loses its meaning. What exactly does that mean and what are the incredible implications this fact has upon our reality? To find out check out this episode of Space Time...

In this video Paul Andersen explains how light travels in photons which can be described as both particles and waves. Einstein showed that photons can be described as particles using the photoelectric effect to show that the energy of a...

Max Planck's theory was  proposed by Max Planck in 1900 revolutionized the field of physics by introducing quantum mechanics and fundamentally reshaping our comprehension of the subject. Planck conducted research on black body...

Will this be the last video I make about SI units? Quite possibly. There's something about being so precise and defining the systems within which science works. When we can more accurately and routinely measure a kilogram, a mole, a...

Photoelectric effect occurs when electromagnetic radiation above the threshold frequency of the given metallic surface, strikes the surface and releases electrons from it. This happens because light is made of massless particles called...

So we know that physics got turned upside down at the turn of the 20th century, but how did that all begin? What was the first thing that set this whole chain of events into motion? Well it all started with Planck and the ultraviolet...
