so it isn't conclusive proof that infinity exists? I mean the trains crash but how come the particle (the bird with ~0 mass) make inifintely many stops? THE TRAINS CRASH, RIGHT??

So let this problem be out of reality (assumming instnataneous change in direction). Then what does it imply?

so what is the conclusion? does it literally mean infinity "exists"? because afterall the trains must crash. But infinity doesn't exist

oh please do programme a simulation, they help a lot. I haven't learned programming. Can you explain what you plotted? (the gradients)? thx

I am not able to solve this equatio, b becomes infinity!

i came up with: summation of [(2)/(3)^b] equals 1. where b is the number of stops.

have you assumed the fact that after the bird started flight the destination train gets near the bird? as you said infinite stops is wrong because it implies that the trains don't collide!

by the way the trains crash 1 sec after they start their motion.

all that doesn't matter! ok asume it is a particle which can "fly" from one of the train to the other and backforth

60 m/s relative to the earth. And the type of bird doesn't matter! It just travels 120 m/s

two trains approach each other at 60m/s the gap between them is 120 m. A bird on one train flies to the other in 120m/s. The bird flies back again. But how many trips would the bird do before the trains crash? thx

can lightning rod prevent the sound of thunder near the area the lightning stroke?

I agree with you homeomorphic, a head start helps in the future. So what parts of math should I cover now? I mean I will take Calculus and nothing else in high school but what can I add by myself like abstract algebra, which will in the future give me a head start like you pointed?

homeomorphic, how about books on algebra( linear, abstract...) and I have feynman's lectures but should I study them right now or in my undergrad days? homeomorphic thanks in advance

I wish to be a particle physicist (theoretical physics). I believe that I must have a very strong basis in maths so I need to complete some maths in high school. Please recommend me the topics to complete (other than the syllabus) and books with difficult questions.
