Music Composer, music recognition software. Composer recognizes polyphonic music from a microphone or other Wave input or file and converts it into Midi sequences. You can sing, whistle or play guitar, piano, flute and so on with your microphone, Composer will automatically recognize and score your music and create standard Midi sequences. No Midi keyboard or musical experience required.
Click Here! to compose music with just your microphone!
AKoff Guitar Assistant designed to assist in visual tuning a guitar with microphone or an electrical guitar connected to PCs sound card. It analyzes in real time a stream of audio signals from WAVE input of your sound card and calculates the main frequency. This frequency is shown by a pointer on graphic guitar signature stamp (frets), comparing it to the proper frequency. Tuning a string now simply means centering the pointer on the appropriate graphic fret.

Quantum Physics Articles
Links from this page are to articles and stories related to quantum physics. There is another page on StarkEffects.com designed to be a primer on quantum physics, this page won't be suited to use as a tutorial, but more like a quantum buffet.
The Hydrogen Atom Wavefunctions
|
Hydrogen Atom Wavefunctions. So, your're sitting around the apartment one day, there is nothin' on the tube, and you start wondering "What are the energy levels of atomic hydrogen? I'd have to know that to figure out the wavelengths of the spectral lines emitted by a hydrogen atom." Then, suddenly, you realize, "Oh my goodness! I'd have to solve the Schrödinger equation and find the the wavefunctions for the hydrogen atom to find out something like that." Here are those wavefunctions and energy levels all spelled out for you.

If you were just wondering what the energy levels of the hydrogen atom are, and how to find them by solving the Shrödinger equation, you are in luck! On this page, we display the hydrogen atom wavefunctions and energy levels which can be scaled to any hydrogen-like atom (single electron ion).

Stark Effect
The Stark Effect is shown here in the splitting and shifting of spectral lines in hydrogen under the influence of an external electric field.

What is the Stark Effect? This article discusses the spectroscopic effect of strong electric fields known as the Stark effect, named for Johannes Stark, the first to experimentally demonstrate the effect.
