61Animal echolocation — Echolocation, also called biosonar, is the biological sonar used by several animals such as dolphins, shrews, most bats, and most whales. The term was coined by Donald Griffin, who was the first to conclusively demonstrate its existence in bats.… …
62Hilbert space — For the Hilbert space filling curve, see Hilbert curve. Hilbert spaces can be used to study the harmonics of vibrating strings. The mathematical concept of a Hilbert space, named after David Hilbert, generalizes the notion of Euclidean space. It… …
63Tuvan throat singing — The Alash Ensemble Tuvan throat singing is one particular variant of overtone singing practiced by the Tuva people of southern Siberia. The art of Tuvan throat singing is a style in which one or more pitches sound simultaneously over a… …
64Harmonic generation — Perturbative Harmonic Generation Perturbative Harmonic Generation is a process where by laser lightof frequency ω and photon energy ħω can be usedto generate new frequencies of light. The newly generatedfrequencies are integer multiples of the… …
65Bristol (software) — Bristol is an open source software synthesizer for Linux. Bristol consists of two components, the emulation or synthesis engine itself called bristol, and a graphical user interface called brighton. As of 2007 there were about 25 keyboards… …
