I actually have a question that falls pretty much in line with the above..
Usually its said that the temperature of the big bang (or "the" singularity or something else equally unclear) was infinite in the beginning.
Now I know that temperature can be defined as in a way: 1/T = dS/dE, so I...
Right, so it is the difference between the resistance of the powerline and the resistance of the end user that makes the real difference.
Thanks for the quick reply :biggrin:
Maybe I can add my question then :biggrin:
Like the previous posters people always talk about how you can transport a large amount of power with minimal losses because you use a low current, and a high voltage in your wires. Then they say that the heat losses are the following:
I^2 x R x...
Right, I figured as much.
I do understand that the inner part of a tree is dead, but thought maybe that the DNA that was initially in there might be good for a while. A while however isn't very useful if you are talking about many 1000's of years for some trees.
Thanks for the replies :smile:
Using dendrochronology to get DNA mutation rates?
A question:
Would it be possible to use DNA analysis in combination with tree ring dating get an accurate DNA mutation rate?
By extracting DNA from the inner rings of a tree, shouldn't it be possible to compare it to the DNA from outer...
