INSANE scientists see the light waves overtaking the observer at a slower rate:

c' = c - v

and deduce that the frequency varies accordingly:

f'/f = c'/c = (c - v)/c

SANE scientists see the light waves overtaking the observer at the same rate (Divine Einstein, yes we all believe in relativity, relativity, relativity):

c' = c

and deduce the same frequency shift:

f'/f = (c - v)/c

Scientists watch a video where the speed of light is shown to vary exactly like the speed of cannonballs:

INSANE scientists start thinking about Newton's emission theory of light. Perhaps this theory is correct after all?

SANE scientists exercise themselves in crimestop and do not start thinking about Newton's emission theory of light:

"Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity."

Pentcho Valev

Scientists get informed that both the Michelson-Morley and the Pound-Rebka experiments have confirmed the variable speed of light predicted by Newton's emission theory of light:

John Norton: "The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE."

Albert Einstein institute: "...you do not need general relativity to derive the correct prediction for the gravitational redshift. A combination of Newtonian gravity, a particle theory of light, and the weak equivalence principle (gravitating mass equals inertial mass) suffices. (...) The gravitational redshift was first measured on earth in 1960-65 by Pound, Rebka, and Snider at Harvard University..."

INSANE scientists are puzzled. Perhaps the emission theory is correct after all?

SANE scientists exercise themselves in crimestop and get convinced in the end that Newton's emission theory of light is absolutely wrong:

"He set to work to exercise himself in crimestop. He presented himself with propositions - "the Party says the earth is flat", "the party says that ice is heavier than water" - and trained himself in not seeing or not understanding the arguments that contradicted them. It was not easy. It needed great powers of reasoning and improvisation. The arithmetical problems raised, for instance, by such a statement as "two and two make five" were beyond his intellectual grasp. It needed also a sort of athleticism of mind, an ability at one moment to make the most delicate use of logic and at the next to be unconscious of the crudest logical errors. Stupidity was as necessary as intelligence, and as difficult to attain."
