  1. Depending on where you published it, you may have already transferred the copyright to the publishing company.

     

    I am very grateful for your come here! but my published book has not been transfered copyright to publishing company.

     

    You need to authorise someone to for the right to copy it, usually in some sort of written contract.

    e.g. "I authorise Mr. Smith to make 1000 copies of my book and sell them at $10 each."

    You may also have an agreement which entitle you to a certain percentage of the gross sales.

     

    You may transfer full copyright, which is essentially giving someone the right to copy something in any way they want.

     

    here's a link to a pretty standard copyright transfer.

  2. Hey there forum, the other day I was "exploding" some potassium with water, I know becase of what I saw that the reaction is:

     

    2 K + 2 H2O ---> 2 KOH + H2

     

    My question is, considering there's extra water, the reaction would continue as following?

     

    KOH + H2O ---> KOOH + H2

     

    Does that happens? And the water is still caustic? Does another reaction take place after that one?

     

    I think this will be appear only temperature has been changed.

  3. can boiled water be supercooled?,it can freeze faster than cold water but can it be supercooled ? i think it can because i think boiled water has no impurities and that it can be supercooled, do you

     

     

    yes! the warm water can freeze faster than cold water !

  4. I want to know how much power(kh-hr?) would I need to convert 1 liter of water to oxygen and hydrogen.

     

    Also I know that adding salt helps speed up the process, does anyone know what concentration leads to highest production level of gases. And if salt has any effect on amount power being used for 1 liter of water' electrolysis.

     

    Thanks guys look forward to interesting replies.

     

    Ben

     

    Where are you from?

  5. If it requires significant speed to be useful, C is the obvious choice. C is also, in my experience, rather painful to use.

     

    If you want something relatively simple that can do the modeling (just not as quickly), try Python. It's fairly simple to learn and you can probably find pre-existing Python code that'll help you do what you want. O'Reilly's Learning Python is a good place to start.

     

     

    yes , I think it is so!
