Re: Wiki Accuracy

I find that the wiki is generally very good on subjects that do not generate controversy. Simon First comment was with tongue firmly in cheek. I agree, if you want to find the formula for the surface area of a tetrahedron or something. Any topic with even a hint of a policy implication is worse tha...

RE: ansak #1 post: I do not believe that clouds, etc. are positive feedbacks for CO2 so I do not think we risk a tipping point or runaway AGW. That being said, if CO2 is a problem then a commercialized Polywell is a part of the solution. In the power grid, CO2 is not released in significant amounts ...

Has anyone been following the discussions (CA and RC) about the Douglas paper? The characteristic fingerprint of AGW is that the Troposphere warms faster than the surface. Only problem is, actual temperature measurements show that the surface is warming faster than the Troposphere. The alarmist posi...

You are going to have to explain that to me. My amateur radio skills are severely atrophied.
Yes, it is just the same two letters that you used to abreviate "fusion". But in CW, it's the thermonuclear end-of-contact abbreviation.

You must have been a 'phone guy :wink:

Using pressure to measure tensile strength is weird, but it makes sense. Testing of materials (I am most familiar with nonferrous metals) is performed by measuring the maximum force (called ultimate strength) that a material will withstand before failure. Using Pa makes sense because the cross sect...

Does theory support such a high flux of low-energy neutrons?
Perhaps you meant low energy NEURONS :wink:

I think the point he was making about a 6mHz Yagi was the size :wink:

Resonant frequency for a practical half wave radiator is (in SAE units) 468/mHz=78 feet, or more than 23 meters! And the element spacing to the reflector is typically .1 - .25 wavelength.
