What sciences are used by each of the major engineering fields (what combos of sciences)?

Question

sciences (physics, chemistry, and biology)

Answer 1

physics and chemistry

Answer 2

The engineering fields don't really "map" to the sciences directly, but I'll give it a try.  Engineering is really applied science.  You might say that scientists are trying to discover new science, while engineers are using existing science to solve the world's problems.

Chemistry is a study in itself and of course maps directly to Chemical Engineering (CE).  Biochemistry leads directly to a biochemical engineer.  The rest comes from physics.  Electrical Engineering (EE) comes from the "electricity and magnetism" part of physics.  Mechanical Engineering (ME) is an incredibly broad field.  The (ME) machine design part comes from the "mechanics" part of physics plus some "material science" and "mechanics of solids".  (ME) Stress engineers use the "mechanics of solids" part of physics.  The HVAC (ME) (heating ventilation and air conditioning) comes from the study of compressible and incompressible flow, part of physics.  Hydraulics (ME) Engineers are also using their incompressible flow study from physics.  Thermal Engineers (ME) use the thermodynamics and heat transfer part of physics.  Civil Engineers and Structural Engineers use physics but unlike mechanical engineers they also build things that interface with the ground and therefore also have classes in "soil mechanics" and flow in open channels.  Nuclear Engineering comes from the nuclear part of physics.
