Had a confrontation with a Chemistry teacher. He was being so condescending saying that 0.9 reoccuring is less than 1 and kept on reiterating that he has a phd in quantum mechanics so he must know everything. Parents, if you have a child who is a white male, the world is their oyster. People can be so stupid. How can this guy get a head of science job?!?!?

Anyways this is the proof he denies that i showed him.

if 0.(9) = 0.9 reoccuring

Consider 0.(9) and assume it is indeed less than one.

By observing that,

0.9 + 0.1 =1, 0.99+0.01 =1, 0.999+0.001 = 1 and so on...

That implies that 0.(9) + 0.(0)1 = 1.

However, the expression 0.(0)1 = 0 because it implies that there exist a finitely bound decimal place where you can 'place' the one. However, since there is an infinite amount of 0's there exists no bound for the 1 to be 'placed' hence,

0.(0)1 = 0.(0)= 0.

So, 0.(9) + 0 =1.

Also, has anyone here ever had an encounter where someone is being so stupid, condescending and arrogant especially while abusing their authority or 'position'?

Edit: oh yeah, I'm the laughing stock of this year. That's why i'm angry etc. Deliberately made to be humiliated.
