Spin the wheel. Where does it stop?

Will it be 

.. S like Science, represented through an Erlenmeyer flask, bunsen burner, different gas taps, something to analyze and warning sign,

.. T like Technology, replicate as lever, steering wheel, control indicators and different tools,

.. E like Engineering, visualize as computer with keyboard to design, model of the project and discarded drafts on the floor,

.. M like Mathematics, symbolize by technical literature, blackboard with arithmetic task and isosceles triangle?

Stop. The decision is made. The arrow shows it.

It is.. A whole new world of knowledge awaits you. Enjoy.

My model uses exactly 217 parts and includes gears for rotation.
