fourier transform experiment


a: A Fourier transform experiment ~
b: hitting on a piano all keys


"Indeed NMR spectroscopy has indirectly much to do with music. Merely a different frequency range is being used. In music, one takes advantage of acoustical frequencies, while in NMR radio frequencies are being applied. In music, one takes advantage of the sound of musical instruments; in NMR, one observes the resonant phenomena of molecules. A Fourier transform experiment is like hitting on a piano all keys at once and then trying to disentangle the simultaneous sounds being emitted by all strings. Our ear is a nearly perfect Fourier analyzer. In NMR, we need a computer to perform the equivalent Fourier transformation."

METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
