  1. you could try giving yourself an overview of the field(s) (what is quantum physics), so you have a fairly good general idea of what the field(s) contains, then work your way or start rather on the basic concepts (atomic structure) and move towards the more complex theory (energies and so forth).. fairly logical, but hope it helps. Otherwise university and textbooks are your best options and obviously the internet..
  2. I was wondering, in regards to what quantum theory is, i know of planks quantum theory of energy, but that quantum theory includes many other components of reality like uncertainty and the wave-functions. So are there various types of quantum theories encompassing the various ideas in the realm of quantum mechanics etc or is there just the 1 quantum theory which contains all the various components..
  3. the idea revolved around the thought that if you knew the position of every particle in the universe at any given time, you would be able to predict the future with precision. However the uncertainty principle unfortunately has the better of it and because of quantum physics we supposedly live in an uncertain universe.
  4. I was wondering whether string theory unifies the other forces via symmetry or fields i've been reading on it and have become a little confused. also would someone be able to explain to me what generalisation (of an equation) means.. in non technical terms if possible, thanks.
  5. Im wondering if anyone could tell me the name of words which give an entirety description to similar or identical objects. Like 'lemon trees' for describing all tree which grow lemons as a whole ? just the english definition.. thanks.
  6. im still not sure that i completely understand. but what exactly does the arc (at the start) mean / imply ..?
  7. I was wondering if someone could please explain to me what this means: the function tan^-1(x) or arctan(x) is a periodical function with the period of pie = 180(degrees) an analogy etc might be useful to me, thanks.
  8. ok, but why are there multiple energy levels for the hydrogen atom when there is only 1 electron ?
  9. I was wondering why and how there is a 'hydrogen spectrum'.. since hydrogen has only 1 electron, so shouldn't it give off/have only 1 colour or frequency not multiple...
  10. for like terms in algebraic expressions, does the rule for only being able to add, multiple, divide and subtract go for just multiplication and division, just addition and subtraction or both ? As in for something like 4x - 6y, can you only end up with 4x - 6y via subtraction because they are unlike, but for something like 4x * 6y, you could up with 24xy ? etc
  11. I was wondering why something like X^2 + 2x doesn't = 2x^3, yet via multiplication would...

    mass ?

    Ok, yep I'm pretty sure I understand that now. Cheers And so do u balance an ionic equation which contains unequal charges among the reactants and products, just like a normal (molecular) equation?
  13. I was reading up on physics and came across a standard form quadratic equation. I know what a quadratic equation is but didnt know they had (a) standard form. So could someone please explain it to me... Thanks.

    mass ?

    Sorry but would someone be able to explain to me the second part of my question... Thanks

    mass ?

    ok yes sorry, i wasn't thinking in terms of moles. thanks.

    mass ?

    i was also wondering if there is/are rule(s) to the elements with which each 'react', as it isn't random and is the balancing of ionic equations essentially the same as normal/general ones ?

    mass ?

    I was wondering how you get the following: 2.00g H + 2.00g O2 = 1.75g H + 2.25g H2O... and is it the case in ionic reactions, that the closest matching ions within the formula of the reaction will come together, so therefore in a reaction the various ions won't just randomly react with whatever other ion..
  18. In physics were using i, j & k (with hats on them) as unit vectors. Are they used across the board ?
  19. I was wondering why we use unit vectors, what's happens if we don't and in the definition of a unit vector, does a magnitude of 1 mean a scalar of 1 (for a that vector) or that the vector itself only represents one/single arrow ?
  20. Ok, so d is anything to worry about then...it's just representing the derivative of the function or something like that. And also how exactly do unit vectors fit into the equation so to speak..?
  21. Sorry, but in dx/dt, where does the d come from and what does it mean ?
  22. but why?, i still don't understand why dividing 1 into a = a^-1...
