an express train is hurtling down the tracks, a teeny tiny fly is heading towards afore mentioned hurtling train that hits teeny fly. as the direction the fly moves changes (from flying toward the train, to moving with the train, stuck to the front). there must be a brief moment when the fly is stationary. therefore the train, being in contact with the fly, must also be stationary.

is this right?

my major is biochemistry and molecular biology. the thing is I like chemistry more than biology. Chem is way more interesting but it is more complicated to understand. Biology is kinda boring sometimes but it is much easier to get except there is a lot more info to grasp. what do you think? is a major in chem harder than my current major?
