    Undergrad Newton's Law of Conservation- Based on a Fallacy?

    Well, the 'arrow of time' for example. That's based on the idea of entropy increasing in an isolated system, right?

    Undergrad Newton's Law of Conservation- Based on a Fallacy?

    The problem is there are no isolated systems. All systems interact with their environments, so this is an utterly meaningless thing to say. In other words, the mechanical properties of all systems can change. ...which don't exist. Meaning the 'most fundamental principles of mechanics' are...

    Undergrad Newton's Law of Conservation- Based on a Fallacy?

    Do you ever lie awake at night worrying about natural laws? How can we 'focus on basic principles', or indeed 'clarify the nature of physical laws' by using a model that doesn't exist in nature?

    Undergrad Question About Bohr's Quantified Shell Model

    I'm sure this has a straightforward explanation and am hoping someone can answer it for me. Looking at this diagram of Bohr's quantified shell model of the atom: http://library.thinkquest.org/C005775/Theory/oldtheory_section3.html ...I don't understand what is preventing the electron...
