  1. Scientific Method in climate science

    Start with the null hypothesis in this case. hint the clues are in the words 'change' and 'null' So suggest a sensible null hypothesis about climate change, qualitative at first. Decide something that would be true if the null hypotheis was true. Then put numbers to it so you can measure it.
  2. Once again, thank you for a productive discussion, rather than just heckling. Yes you are correct work done = moment x angle turned and since the dimensions of moment are the same as those of work/energy angle is regarded as dimensionless. Good point +1 However energy involved in a static lever is zero, but the moment may not be. What say you ?
  3. Then I'm sorry, but you haven't been listening and only seem to see what you want to see.
  4. It is a discussion, not a battleground. All views are welcome. I hope to learn something from the discussion; if others do vas well, that's great. Exactly. The ratio of energy to moment in say a static lever is meaningless since they are different things even though they have the same dimensions. But the ratio of say inertial forces to viscous ones has meaning and is dimensionless since both numerator and denominator are of the same nature. The ratio of distance to time is also not meaningless. Since they are not the same and their dimensions are different the ratio produces a new quantity. But even that may not be enough to have real meaning in some cases.
  5. Perhaps there was a message rather than a meaning in that equation Mindlessly following rules can lead to difficulties.
  6. Forgive me. I thought I posted in the Philosophy section. And haven't we got a live thread discussing the fact that Philosophy and Science can each address matters unavailable to the other?
  7. The definition of nothingness exactly

    Still avoiding answering then?
  8. The definition of nothingness exactly

    Thanks. I have two simple points of logic to make. 1) Given that nothing 'exists' (or existed if you prefer) and that something exists it cannot be held that nothing has no properties since there must be somewhere (even if only in my mind) where nothing exists and also somewhere (else) where something exists. So nothing has the property that it shares a boundary with something. 2) To create is a transitive verb which therefore requires a creator. No problem with that. But even the authors of the Bible and past Christian material understood this. That is why for instance the early authors wrote the hymn line "Begotton not created" But the existance of creators and creations does not mean that other methods/modes (non creative) of appearance are precluded. For instance a) spontaneous appearance or b) Happenstance
  9. The definition of nothingness exactly

    Is that why you keep avoiding my questions?
  10. Rearrange that equation to show that energy = 5 times moment (in suitable units) Is that so?
  11. The definition of nothingness exactly

    Maybe so, can you provide a reference for this definition? Let me get this quite straight. nothing is defined as that which produces nothing? or did you have better wording in mind, because nothing produces nothing is not a definition of nothing, unless it is recursive.
  12. The definition of nothingness exactly

    I am trying to be open minded about things, I really am. So I asked a civil question, which I will repeat for your convenience, after reminding you that the rules here, and common civility require you to attempt an answer. For you information, Nothing may or may not have properties. I think this has been discussed before. Or is you mind already biased?
  13. Salt water eletrolysis idea

    What exactly would be the purpose of the reverse osmosis module? What would it do? And what do you mean by connect?
  14. The definition of nothingness exactly

    Randolphin, Do you regard the verb 'to create' as a scientific word or just plain English?
