    The Professional (Model PP/222 and PP/221) contains a single keyboard with grey keys. The vibrato uses a phase shifter circuit that is placed after the main oscillators, as this was the only way to make individual controls for each voice work. [27] The Professional Duo is a double-manual version with bass pedals, a swell pedal and a slalom ...

    Smith's proof has unleashed a debate on the precise operational conditions a Turing machine must satisfy in order for it to be candidate universal machine. A universal (2,3) Turing machine has conceivable applications. [19] For instance, a machine that small and simple can be embedded or constructed using a small number of particles or molecules.

    An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.

    Electromechanical systems saw a massive leap in progress from 1910-1945 as the world was put into global war twice. World War I saw a burst of new electromechanics as spotlights and radios were used by all countries. [7] By World War II, countries had developed and centralized their military around the versatility and power of electromechanics.

    en.wikipedia.org/wiki/Electric_power_industry

    The electric power industry covers the generation, transmission, distribution and sale of electric power to the general public and industry. The commercial distribution of electric power started in 1882 when electricity was produced for electric lighting. In the 1880s and 1890s, growing economic and safety concerns lead to the regulation of the ...
