As limestone, calcium carbonate is a biogenic rock, and is more compacted than chalk. As marble, calcium carbonate is a coarse-crystalline, metamorphic rock, which is formed when chalk or limestone is recrystallised under conditions of high temperature and pressure.
Definition: A wavefunction is a function describing the probability of a particle's quantum state as a function of position, momentum, time, and/or spin. Wavefunctions are commonly denoted by the variable Ï.
The idea with a Mu wave brain-computer interface (BCI) is that I'll use my EEG system to listen to my brain waves. Mu waves are simple but strong signals in the Alpha band that appear in the sensorimotor (SM) cortex when you relax parts of your body.The Mu waves go away when you move (or *think* about moving!) those parts of your body. Supposedly, different regions of the SM cortex correspond to different portions of your body. to do this, I will modify my PC software to process the data and make a dinging sound or something in proportion to the strength of the signal at 12 Hz. This live feedback will tell my I'm doing the right thing. As a result, I should be able to train myself to do a better job making Mu waves.
