In the following video eventhough people know that when handlebar of the bicycle is turned left the wheel of that bicycle is turned towards right and vice versa, they can't ride that new bicycle instantaneously without any practice. Why is that so? Why can't we do something even though we know how it works? what is the scientific explanation behind it?
One more hypothetical question relating to this. Let us consider a boy who never swam in his life, if theoretically came to know each and every aspect of swimming ,learning for several years. If one day after these years he fell into a large swimming pool, can he decently swim by applying his theoretical knowledge.
This is not a thought experiment as in philosophy.I want to know scientifically how his knowledge and doing of swimming correlate?
