  1. if we look at chem, imagine the possible number of games playable in Chess, there are only 64 squares and 32 peices, we have well over 100 elements and near infinite "squares".

    so you can imagine how many orders of magnitude greater the possible chemical combinations can be!

    so really it remains how many of them are of any practical use?

    and that`s anyones guess really.

  2. all of which are used in radio applications and some of the old Music Synthesizers too ;)

    although where a freq is too high and needs to be resolved to something lower, dividers or hetrodyne are commonly used, in radio the IF and mixer does that too.


    but sure, when you have either converted to a simple voltage, you can use that ramp up or down any output you like.

  3. my "Deal" is that Chemistry is a Science, and Exacting science at that, so "get some eggs" requires backing up with science, something you failed to do when asked.


    there is no room for half answers or speculations (or Opinion) here.

  4. so you don`t know?

    then why waste our time posting in the Chemistry (Science) area at all? if you have nothing useful to offer I`ll thank to keep out of these forums in future, and leave the replies to those that DO know some science.

  5. I sincerely doubt that 0.5g in a test tube went "boom"!

    AN has a critical diameter of at least 10cms even then, with the best of intentions DDT would be a low order detonation!


    you`de likely got impurities in there such as dust that was burning much like as you mentioned the jelly bean in chlorate, AN is a fairly good oxidiser when hot like that.


    it Must be mentioned however that heating AN to those sort of temps is just plain dumb and won`t yield a good result for N2O production, you`v simply wasted some good chemical.

  6. well, with the use of registers in that way you can do what`s called Polling, and if you don`t mind using a few extra clock cycles to do this, you can have Several banks of 64k if you like, the C= 128 did this.

    and the Zilog Z80 specifically incorporated this fuction in its architecture as well as boasting 16 bit internal registers (the 1`st 8 bit CPU to do this).

    oh yeah, and for the record the C= 64`s cpu was only BASED on the 6502, it wasn`t an actual 6502.

  7. if we ignore the control lines, you`ll see a ram chip has address and data lines, the Data lines in a 1 byte wide chip has 8 lines and can represent any number from 0 to 255.

    the address lines are like little storage boxes, and each box you can put in any number between 0 and 255 (data), a bit like the old pigeon holes or the way mail used to be sorted, one box for all the letters going to an address.


    to 2^64 is is simple too, take the number 2 and then double it, you get 4, double that you get 8, 16, 32, 64, 128 etc...

    in your chip, you have to keep doubling it 64 times, that`s a Massive number!


    think about it, a chess board has 64 squares, put a small piece of paper with any number between 0 and 255 writen on it, on square number 1, then 2 peices on sqr 2, 4 on sqr 3, 8 on 4, 16 on 5 etc...

    by the time you get to sqr 64, you`ll be an old man, have used up several pens, and have a pile of paper probably bigger than the empire state building! :D

  8. it May also help to remember that a Rodent simply means a mammal that`s teeth continue to grow (a bit like our fingernails do), the "dent" (dentia, dental etc...) in the name is a bit of a give-away ;)

    so you Could have them evolve into all manner of creatures if you wanted to, even Giraffe like if there was a reason to reach higher for food.
