What are isonitriles good for? The Passerini reaction! This is a very neat multi-component reaction that is good for generating chemical libraries. When was it invented? What's the mechanism? What are we doing with it today? Let's find out!

The video explains the concept of redshift and blueshift in the context of galaxy movement and how it relates to the shift in wavelength of light emitted by a galaxy. The video then shows how to use an equation to calculate the shift in...

The video is a lecture that explains the two features of a wave, namely wavelength and amplitude. It starts with a demonstration of a transverse wave and illustrates how the wave propagates while oscillating. The peaks and troughs of the...

The pigments in our food all get destroyed on their way through our digestive system...so where do the colors of our poop and pee come from?

This video discusses the properties that all waves have in common, including amplitude and wavelength. It also demonstrates how to calculate the speed of a wave using the equation v = Fλ, where v is the wave speed, F is the frequency in...

Waves transfer energy from one place to another. You should already know how to describe them in terms of frequency, wavelength and amplitude In this video we’re going to look at the two ways they can be classified. Waves are produced as...

This video discusses the relationship between the temperature of a body and the rate at which it emits and absorbs electromagnetic radiation, particularly infrared radiation. The video explains how the relative rates of emission and...

The video explains two important features of a wave: the frequency and the time period. It uses a visual representation of a transverse wave and a longitudinal wave to show the peaks, troughs, amplitude, and wavelength of a wave. The...

Swift 2 is a multi-paradigm programming language that has expressive features familiar to modern functional languages, and does not forget the object-oriented features of Objective-C. Things that took a block of code in...

Today Phil’s explaining the stars and how they can be categorized using their spectra. Together with their distance, this provides a wealth of information about them including their luminosity, size, and temperature. The HR diagram plots...

***My apologies for the loud music. This is an older video and I was really into background music when I made this. I've since learned my lesson for later videos. 🙂

Travel back to 'What Were Bronze Age Homes Like?' to peek inside the dwellings of the past! A quick, intriguing look at ancient living, ideal for young time travelers curious about history.

Through live action footage and animated diagrams students will come to understand that refraction is the bending of light rays when they go from one medium to another medium of different density. The program explains why light refracts...

Upon viewing the The Nature of Waves video series, students will be able to do the following: Define waves as traveling disturbances that carry energy through matter or space. Explain that waves do not actually move matter. Instead,...
