gases in the normal breathing process, the blood stream absorbs oxygen
from air in the lungs, while carbon dioxide passes from the blood to the
air. When you hold your breath, the exchange of gases slows, as "stale"
air in the lungs is no longer replaced by "fresh" air. Oxyg .....

for words if they have been categorized and for pictures if they have been
named. Experiment 3 showed the same results as the previous two

and Fleischman are researching it today.
Detailed Description of Chemical Process
The theory to how this fusion works is the Muon Theory. The muon
theory is as follows: Speeding muons knock electrons out of their orbits
around deuterium and tritium atoms. Muons replace the electrons and form a
smaller atom. This "muo-atom" the n captures another nucleus. The muon
orbits more tightly around the two captive nuclei leading them to overcome
their natural repulsion of each other and fuse. This reaction produces a .....

These involve a precise, sequential consideration of data, obtained by clinical observations, interrogation to obtain a detailed case of history, and palpation of the pulses.

"Physiologists found a surprising order in the chaos that develops in the human
heart, the prime cause of a sudden, unexplained death. Ecologists explored the
rise and fall of gypsy moth populations. Economists dug out old stock price
data and tried a new kind of analysis. The insights that emerged led directly
into the natural world- the shapes of clouds, the paths of lightning, the
microscopic intertwining of blood vessels, the galactic clustering of stars."
(Gleick, 1987)
The man most responsible for coming up with the Chaos Theory was
Mitchell Feigenbaum, who was one of a handful of s .....
