How is it that Beethoven, who is celebrated as one of the most significant composers of all time, wrote many of his most beloved songs while going deaf? The answer lies in the math behind his music. Natalya St. Clair employs the...

Mathematician Mark Kac asked the question "Can we hear the shape of a drum?" It was a question that took over 20 years to answer. Sine waves, fundamental frequencies, eigenvalues, this episode has got it all!

This video is about how the way we describe the world can influence the way we perceive it. In particular, with regards to Bohmian mechanics, Schrodinger wave functions, Feynman path integrals, and Galilean...

Woody Norris shows off two of his inventions that use sound in new ways, including the Long Range Acoustic Device, or LRAD. He talks about his untraditional approach to inventing and education, because, as he puts it: "Almost nothing has...

Reuben Margolin is a kinetic sculptor, crafting beautiful pieces that move in the pattern of raindrops falling and waves combining. Take nine minutes and be mesmerized by his meditative art -- inspired in equal parts by math and nature.

In this tutorial I show how I synthesized the sound of hydrogen for the "Sound of Hydrogen" video using mathematica - it's a little technical, but you've been requesting it!

In this video Paul Andersen explains how a sine or cosine wave can describe the position of the wave based on wavelength or wave period. A wave function can the position of a wave as a function or the amplitude and wavelength or the...

It's not magic; it's science! Build your own acoustic levitator to make objects float in midair using invisible sound waves.<br/>

In this video, you will learn how the linear model is about to forecast for a sine wave.

In this video we learn how three phase electricity works from the basics. We explain how three phase electricity is generated, how the voltages vary, how to calculate the voltages and vrms, what frequency, hertz and cycle mean and how...

How to use a multimeter. Find out in this tutorial for transistors, resistance, voltage, current, continuity, AC, DC, batteries, frequency, diodes, LED's, capacitors, temperature and much much more.

Full wave bridge rectifier. In this video we look at the full wave bridge rectifier, the half wave rectifier the full wave rectifier, center tapped transformers, diodes, load, oscilloscope, waveform, DC, AC, voltage current, capacitors,...

How inverters work. In this video we take a look at how an inverter works to convert direct current (DC) into Alternating current (AC). Inverters are used increasingly throughout industry as well as building services HVAC systems to...

Half wave rectifier explained - how to convert AC alternating current into DC direct current using diodes.

Full bridge rectifier - how to convert AC alternating current into DC direct current. Using capacitors to filter the rippled DC wave into smooth DC with experiments.

Learn how AC voltage varies with AC since wave and how to calculate the Vrms root mean squared, vmax, peak voltage, the frequency and voltage of different countries.

Electrical generator basics. Learn the basic operation of an electrical generator, learn how magnets are used to generate electricity in a coil of wire. We then cover 3 phase three phase electricity and briefly the star configuration in...
