2001, 357ff). Entrainment refers to the synchronization (also know as resonance) of an existing frequency, such as the brain in a specific brainwave state, to an external frequency stimulus, such as one provided by a PEMF device. He termed this effect as “odd sympathy”. Christiaan Huygens. Entrainment is a concept first identified by the Dutch physicist Christiaan Huygens in 1665 who discovered the phenomenon during an experiment with pendulum clocks: He set them each in motion and found that when he returned the next day, the sway of their pendulums had all synchronized.

... the ideas of mass, weight, momentum, force, … It was in Paris, 1666, that Christiaan Huygens, the Dutch physicist, became rather baffled. In 1665 the Dutch physicist Christiaan Huygens noticed that two pendulum clocks in his room tended to Swing in Sync. Such entrainment occurs because small amounts of energy are transferred between the two systems when … Among others, Dutch physicist Christian Huygens introduced the concept of Entrainment in 1666 after he noticed that the pendulums of two clocks mounted on a common board had become synchronized, and his subsequent experiments duplicated this phenomenon. The same happens with fireflies, cardiac pacemaker cells, menstrual cycles, birds in flight, walking, dancing, circadian rhythms in animals, quantum gravity theory, dialogues and people in a crowd. He … About Entrainment Thursday, August 26th, 2010. Two connected Systems always Entrain … The two pendulum clocks synchronized with their pendulums swinging 180° out of … He combined Galileo's mathematical treatment of phenomena with Descartes' vision of the ultimate design of nature. While working on the design of the pendulum clock, Huygens found that when he placed two of them on a wall near each other and swung the pendulums at different rates, they would eventually end up swinging in at the same rate. Numerous other mechanical instances of this phenomenon This is due to their mutual influence on one another. 1629 - 1695AD.

Beginning as an ardent Cartesian who sought to correct the more glaring errors of the system, he ended up as one of its sharpest critics. The classic example of entrainment is that of pendulum clocks, which were observed by the Dutch physicist Christiaan Huygens to synchronise when placed on or suspended from a common support (see Pikovsky et al. Huygens had invented the pendulum grandfather clock, along with a wide range of classic mechanics and mathem Discovery of Entrainment The history of entrainment is linked to Dutch scientist, Christiaan Huygens in 1665. Entrainment is a concept first identified by the Dutch physicist Christiaan Huygens in 1665, who discovered the phenomenon during an experiment with pendulum clocks. Huygens was the greatest mechanist of the seventeenth century.
