Frequency

1. (Science: physics) The number of occurrences of a periodic or recurrent process per unit time, for example the number of vibrations of a particle per second or the number of repetitions of a complete wave form (cycles) per second.

2. (Science: statistics) The number of members of a population or statistical sample falling in a particular class.

3. Relative frequency, the average number of occurrences of a particular event in a large number of repeated trials.

Electromagnetic fields generated by the human body

I read this thread with interest. I'm surprised there is no mention of Leon Trotsky's work. For example his work with low frequencies and how the US military, some believe have used to develop weapons based on this. Search for trotskey on youtube and look for a 45 minute or greater ...
