try logic
you can test it. place an o-meter in line. Open the door read the current. Close the door read the current. You should see that the door open causes greater current flow.... or try Wiki
Logical reasoning
From Wikipedia, the free encyclopedia
Inductive and deductive reasoning
Informally, two kinds of logical reasoning can be distinguished in addition to formal deduction: induction and abduction. Given a precondition or premise, a conclusion or logical consequence and a rule or material conditional that implies the conclusion given the precondition, one can explain that:
Deductive reasoning determines whether the truth of a conclusion can be determined for that rule, based solely on the truth of the premises. Example: "When it rains, things outside get wet. The grass is outside, therefore: when it rains, the grass gets wet." Mathematical logic and philosophical logic are commonly associated with this style of reasoning.
Inductive reasoning attempts to support a determination of the rule. It hypothesizes a rule after numerous examples are taken to be a conclusion that follows from a precondition in terms of such a rule. Example: "The grass got wet numerous times when it rained, therefore: the grass always gets wet when it rains." While they may be persuasive, these arguments are not deductively valid, see the problem of induction. Science is associated with this type of reasoning.
Abductive reasoning selects a cogent set of preconditions. Given a true conclusion and a rule, it attempts to select some possible premises that, if true also, can support the conclusion, though not uniquely. Example: "When it rains, the grass gets wet. The grass is outside and nothing outside is dry, therefore: maybe it rained." Diagnosticians and detectives are commonly associated with this type of reasoning.

There's an app for that.
Place your timed camera (flash off) in there and see what happens.

What would Albert Einstein have said?
Logic will get you from A to B. Imagination will take you everywhere.
