This video is about the "Kelvin wake" shape of water wakes behind boats - we talk about mach angle, dispersion, superposition of many waves, and how these all lead to the pattern of a wake. We don't get into Froude number though...

Our favorite fast radio burst, FRB 121102, brings us one step closer to understanding its source, and astronomers have a new theoretical upper limit for star masses.

Where did astronomers finally conclude that the 'Weird! Signal' was coming from? What has Elon Musk been up to with SpaceX and the Falcon Heavy rocket?

Population ecology is the study of groups within a species that interact mostly with each other, and it examines how they live together in one geographic area to understand why these populations are different in one time and place than...

The video titled "Dispersion of Population" explains population density and dispersion.

This Science 6 instructional video discusses population density and dispersion.

Pupil outcome: I can use the different measures of central tendency and spread to compare two sets of data. Key learning points: - Statistical summaries of data can be used to make inferences about that data. - Two sets of statistical...

The light spectrum is the collection of colours that are generated when light is dispersed through a medium, such as a prism. This dispersion reveals the various wavelengths of visible light, with each wavelength corresponding...

Explore the fascinating journey to uncover the universe's missing baryons—ordinary matter that had eluded scientists for decades. From the origins of baryonic matter after the Big Bang to groundbreaking discoveries using fast radio...

The physics behind rainbows and surprising facts about rainbows.

Optical physics. Explaining and what Refraction, total internal reflection and dispersion is. Refraction is the bending of the light rays path, when it passes a new medium. When the index of refraction is greater in the new medium and...
