So What are we<br />
learning about<br />
today??<br />
<strong>Radiocarbon</strong><br />
dating...<br />
So It can tell me<br />
how old the<br />
sweaters I got from<br />
goodwill are?<br />
RAdiocarbon dating? That's<br />
great, cause there's this<br />
<strong>Radiocarbon</strong> i've been wanting<br />
to date, but she doesn't like<br />
me all that much - what<br />
should i do?<br />
I think you should buy her<br />
flowers, but that's not what we're<br />
talking about. I mean the kind of<br />
radiocarbon dating where we take<br />
Carbon 14 atoms to determine how<br />
old something is...<br />
No - it<br />
has to<br />
be<br />
some<br />
thing<br />
much<br />
older..
Like a dinosaur fossil?<br />
No, that's too old.<br />
It has to be in the range of a couple<br />
to several thousand years old to use<br />
effectively, Because carbon 14's<br />
halflife is 5,730 years...<br />
I guess I don't get it.<br />
Maybe if I saw a bunch of<br />
people dressed like<br />
atoms demonstrating<br />
the concepts about<br />
radiocarbon dating I<br />
could inderstand it...<br />
Your words<br />
here...
These people all Represent Nitrogen 14 atoms floating<br />
around in the atmosphere - Suddenly a comic Ray comes in.<br />
then through violent collisions with atoms in the<br />
atmosphere, the cosmic ray produces an energetic<br />
neutron.<br />
dude, whereyagoin?<br />
This neutron flies<br />
into another atom of<br />
n14 and knocks out me<br />
- a proton
This just changed us to<br />
Carbon 14!!<br />
this radioactive form of carbon is<br />
incorporated into carbon dioxide that living<br />
organisms absorb through photosynthesis<br />
or ingestion. The small fraction of carbon<br />
in living organisms that is c14 stays<br />
constant until the organism dies...<br />
Then the c14 starts to<br />
decay back into n14. the<br />
ratio of c14 to c12 (a<br />
stable form of carbon)<br />
can be used to determine<br />
how long ago the plant<br />
or animal that absorbed it<br />
died. This is based on c14's<br />
halflife of 5,730 years,<br />
and the laws of<br />
radioactive decay.<br />
after the<br />
neutron<br />
knocked the<br />
proton out of<br />
the picture...
ok, I get now. but I<br />
still have one more<br />
question...<br />
what kind of<br />
flowers should I<br />
get her?<br />
