Topic: A damning poll?

[Toasty0]

 

I would think that a poll asking that question on a dedicated space exploration site would garner a higher percentage of positive responses for NASA.

Has NASA really done that bad a job?

Best,

the results are better than I expected.  People fail to realize the number of things in society that came from NASA and space exploration- microwave ovens, velcro, teflon, the list goes on and on.  All they see are the rocks brought back from the moon.  They fail to look deeper to see the advancements from the R&D of space exploration that benefit us all.

You are actually correct about all the Inventions That NASA has Made, But you made on small error there Bro. NASA did not invent Teflon. I used to believe they had also untill I had read a book discusiing this. It turns out a Man named  Roy Plunkett invented It.

 

Quote:
 PTFE or polytetrafluoroethylene was discovered on April 6, 1938 by Dr. Roy Plunkett at the DuPont research laboratories (Jackson Laboratory in New Jersey). Plunkett was working with gases related to Freon® refrigerants when upon checking a frozen, compressed sample of tetrafluoroethylene, he and his associates discovered that the sample had polymerized spontaneously into a white, waxy solid to form polytetrafluoroethylene or PTFE.

PTFE was first marketed under the DuPont Teflon ® trademark in 1945. The molecular weight of Teflon can exceed 30,000,000, making it one of the largest molecules known. The surface is so slippery, virtually nothing sticks to it or is absorbed by it. No wonder Teflon was choosen to be used on non-stick cooking pans.

Chemical Description of Teflon
Teflon is a colorless, odorless powder, a fluoroplastic with many properties which give an increasingly wide range of uses.

 

I know I was abit shocked myself when I first heard this and confermed It for myself.

BOT: I think It's a pretty food estimate of ost people who follow NASA sites ETC.

Sorry to hijack, but I've always wondered... If nothing will stick to teflon, how do they stick it to the pan?  

[Iceman]

It doesn't, it comes off in your food slowly.

After posting, I had wondered about teflon, if I should have put it in there, and looks like I shouldn't have, oh well.  The only point I wanted to make was the enormous amounts of technological progress that were made in order for us to get to the moon.  Progress that has paid off more than ten fold.  Obviously, going to gather some rocks off of the moon wasn't worth it within itself, it was about the journey, not the destination, and the endless possibilities that were created because of it.
I hate short dighted people,

Duct tape.

I believe I read once that it was a type of electrical force bonding; like ionic bonds. Other than that; on a microscopic level no surface is completely smooth. Viewed under a microscope the pot's surface is riddled with bumps fissures burrs and so forth. I'd imagine that a fluid would deform to fill in those defects and if hardened would not come out like the interlocking pieces of a puzzle.

Right, and so the PTFE is weakly adhering to the metal surface.  Repeated hot/cold changes, scrapings (especially), etc., and as Iceman said, you're eatin' it.  Fortunately, it's tasteless and will just pass right outta you.  Amazing stuff.

But as for NASA, the problem I and probably the rest of the 60% have with it is that it's so bureaucratic... and political.  They don't always make the smartest organizational or procedural decisions.  But when they're on, they're ON!
