If you could survive a trip to the very first moments of reality as we know it, what color would you see?

How many times can I half the distance between my hands? Assume perfect coordination and the ability to localize my palms to the quantum level. 15 halvings gets them to within a cell’s width. 33 to within a single atom, 50 and they’re a...

The search for a single number: the hubble constant, which is the rate of expansion of our universe, has consumed astronomers for generations. Finally, two powerful and independent methods have refined its measurement to unprecedented...

Sometimes our mathematical hacks point to strange new aspects of reality. For example Max Planck used a quantization trick to figure out the spectrum of light emitted by hot objects. The quantization part of his math trick was meant to...

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...

This week in SciShow News, there's a new kilogram in town, and we might be closer to understanding why people love coffee so much!

June 28 is Tau Day! Join SciShow as we celebrate circles by exploring the many uses of twice pi.

This week in SciShow News, there's a new kilogram in town, and we might be closer to understanding why people love coffee so much!

One of the most amazing facts in physics is that everything in the universe, from light to electrons to atoms, behaves like both a particle and a wave at the same time. But how did physicists arrive at this mind-boggling conclusion? Chad...

In this video Paul Andersen explains why light is important in probing matter. Light travels in photons and the energy of individual photons is determined by Planck's equation. Infrared spectroscopy is useful in detecting the...

In this video Paul Andersen explains how matter can act as a wave at the nanoscale. Louis de Broglie showed that the wavelength of matter can be calculated using the momentum of an object and Planck's constant. The Davisson-Germer...

e=mc2... it's a big deal, right? But why? And what about this grumpy cat in a box and probability? In this episode of Crash Course Physics, Shini attempts to explain a little more on the topic of Quantum Mechanics.

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...

The Origin of Quantum Mechanics (feat. Neil Turok)

In this video Paul Andersen explains how matter, like light, can be treated as both a particle and a wave. Louis de Broglie proposed that matter could act as a wave and described the wavelength of matter as a function of Planck's...

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...

De Broglie's equation, formulated by Louis de Broglie in 1924, introduces the concept of wave-particle duality, suggesting that all matter exhibits both wave-like and particle-like properties. The equation is expressed as λ=h/p; λ is...

Dark Flow. We investigate why hundreds of galaxy clusters are rapidly drifting towards a specific point just outside the known universe.

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...

Quantum physics deals with the foundation of our world – the electrons in an atom, the protons inside the nucleus, the quarks that build those protons, and the photons that we perceive as light. These constitute everything that we are...

In part 3 of INET's interview with John Kay, he tells us what the London Tube map and Max Planck can tell us about oversimplifying systems and models

Particle-on-a-Ring Example #2: Calculate Energy, Wavelength, and Momentum

In this video, we use the following equations to interconvert between and do calculations with Frequency (λ), Wavelength (𝝂), & Energy: 1) E=h𝝂 2) 𝝂=c/λ 3) E=hc/λ
