quote.....Earlier, it was stated that the key to improving cut quality was 
increasing arc constriction while preventing double arcing. In the water 
injection plasma cutting process, water was radially injected into the arc in 
a uniform manner as shown in Figure 10. The radial impingement of the water 
at the arc provided a higher degree of arc constriction than could be 
achieved by just the copper nozzle alone. Arc temperatures in this region are 
estimated to approach 50,000°K or roughly nine times the surface temperature 
of the sun and more than twice the temperature of the conventional plasma 
arc. The net result was improved cut squareness, increased cutting speeds and 
the elimination of dross when cutting mild steel. Radial water injection arc 
constriction was developed and patented in 1968 by Richard W. Couch Jr., 
President of Hypertherm, Inc.

quote:
Through the release of atomic energy, our generation has brought into the 
world the most revolutionary force since prehistoric man's discovery of fire. 
This basic force of the universe cannot be fitted into the outmoded concept 
of narrow nationalisms.
For there is no secret and there is no defense; there is no possibility of 
control except through the aroused understanding and insistence of the 
peoples of the world. We scientists recognise our inescapable responsibility 
to carry to our fellow citizens an understanding of atomic energy and its 
implication for society. In this lies our only security and our only hope - 
we believe that an informed citizenry will act for life and not for death.
A. Einstein, 1947 d.C.

Next Quote..... 

The U.S. government (1938) decided to keep the science of the atomic bomb 
devices secret and develop the radioactive metals industry. This let the 
nuclear genie out of the bottle. They failed to keep the science secret. This 
makes control, on the amount, location, and sources of all radioactive 
metals, a requirement. A public domain nuclear bomb makes it necessary to put 
in the genie back in the bottle. The name of my bomb design is Genie Bottler. 
I will bear no responsibility for any deaths from the irresponsible decision 
of 1938 until all radioactive metals and the sources of them are under 
international control and maximum security. It is a world that requires its 
best science, in the hands maximum number of scientists, to solve the 
problems the technology has created, and all the other unknowns it is capable 
of solving. -Thomas Hulon Jackson 1987 AD

As far as the laws of mathematics refer to reality, they are not certain; as

it?"

comprehensible." --Albert Einstein (1879-1955)
"If one studies too zealously, one easily loses his pants." --Albert Einstein

  equations is reasonable from a logical standpoint, but this does not
  prove that it corresponds to nature.'  You are right, dear skeptic.
