Mechanical machine
* All mechanical machines are made by combining simple machines.
+ Simple machine: Tools :: Machines :: Physics
  * A 'simple machine' is a device that can change the direction or the magnitude of a force, or the point where it is applied. This is done so that the force can be used to do work. All mechanical machines are made by combining simple machines.

Mind machine
* are today's answer to ancient ceremonies and rituals
  - tools for gently inducing a calm, centered, and euphoric state
* come in a number of forms and flavors.
* play upon the best in our senses.

Molecular machine
* are just small machines.
* can make more molecular machines, which can make yet more molecular machines.

### device | machine:

Motor
* All motors create heat when they run
  - run on magnetic principles
* Most motors act as electric generators
  - become generators
* Most motors convert electrical energy
  - power
* Most motors create forces
  - magnetic forces
* Most motors have load
  - wires running through it, or to give it structure, and include solder
  - make sound
  - produce torque
* Most motors provide energy
  - require electricity
* Most motors transform electrical energy
* Most motors use circuits
  - electromagnets to cause mechanical rotation, which can do work
* Most motors use in applications
  - industrial applications
* Provides electrical movement for sewing machines.
* Some motors are powered by batteries
  - wound with large numbers of poles for special purposes
  - can operate on two different voltages, depending upon how it is built and connected
  - contain no gears and spin very fast, and have little if any torque
  - create resistance
* Some motors have commutators
  - motor coils made of superconducting materials, which greatly reduce energy loss
  - produce electricity
  - require the transistors that are more sensitive
  - spin propellers
  - turn propellers
* Some motors use batteries
  - copper wire
  - feathers
  - work on principles
* are agents
  - examples of reactive devices
  - inventions
  - located in repair shops
  - machines that convert electrical energy into mechanical energy using magnetic forces
  - mechanical things and take time to react
  - part of treadmills
* can also serve as structural components of launch vehicles or spacecraft.
* convert electrical energy to mechanical energy
  - electricity into mechanical energy to perform various jobs
* develop builds more than just their muscles.
* drive machinery.
* have designs
  - large thermal time constants and can stand momentary harmonics so do transformers
  - many uses in fluid power systems
* helps maintain warmth of bath water by releasing thousands of heated bubbles.
* includes sections.
  - which converts electrical energy into mechanical energy
* neurones transmit messages the other way - from the brain to the muscles.
* play a crucial role in many aspects of cell function.
* refers to muscle movements.
  - four times as much power to start as they do to run
* responses to pseudo-regular auditory patterns.
* run while cold.
* spin blades
  - fan blades
* store energy.
* transfer power into work, like electrical power into mechanical work.
* turn, masses accelerate, springs oscillate, and lamps light up.
  - electricity to generate temporary magnetism in wire coils
  - less energy
  - magnets and electromagnetism to convert electric power to mechanical power
  - the majority of the electrical energy generated in the United States

### device | machine | motor:

Autonomic nerve
* All autonomic nerves are motor.
* go to the bladder
  - heart
  - penis
  - stomach, intestines, and other parts of the digestive system
  - vagina

Composite motor
* get their name from the chemicals used to make up the propellant.
* use the same fuel as the space shuttle's solid boosters.
