    Just for anyone who's doing any late night Mathematics/Studying/Procrastination (the most likely option), here's a small meme to cheer you up:
    Unfortunately that is incorrect, because the LOTF is very likely to be opposite but greater. :fyi:

    Personally I like "ansatz".
    It's a great word. I learnt it in "The Quantum Story"

    Then you should have used some kind of proposition involving "all" rather than "every", and even then it's still probably greater. :nah:

    I actually enjoy Mathematical Physics. I'm more of an applied Mathematician than anything (if I could even call myself a mathematician with the morsel that I know. )

    It can either be used for 'a shameful act'. Or 'something which deserves slander/calumny - a despicable act/one which can be reprimanded'. It is, as his views are reprehensible (those views being so pedantic). :argh:

    How would you use it? (See below).

    If this still happens at PhD then perhaps the question is whether I should be in a PhD at all rather than something else.

    Disproof 39

    The proposition: p(x)+p'''(x)\geq p'(x)+p''(x),\ \forall x \implies p(x)\geq 0 \ \forall x

    It's contrapositive:  p(x) < 0 \ \forall x \implies p(x)+p'''(x) < p'(x)+p''(x),\ \forall x
    Are you sure that's the contrapositive?

    The for-alls should turn into exists. Hence x=4 not satisfying your last line is no contradiction, as long as there is at least one value of x that does.

    If a statement is "p(x) \geq 0  \ \forall x", then why wouldn't the negation be "p(x) < 0 \  \forall x"? I don't see how/where exists should come into it..
    The negation of any statement of the form \forall x. \phi\left(x\right) is \neg\forall x. \phi\left(x\right), which is equivalent to \exists x. \neg \phi\left(x\right). However here you have \forall x. \neg \phi\left(x\right), which is not equivalent. Example:

    "Not all students on TSR are mathematicians."

    is not equivalent to

    "All students on TSR are not mathematicians."

    EDIT: saw your edit
