Big Climate's strange 'science'

You are global warming

Good God.

I have never seen such a dearth of scientific thought in my life.

Chaos theory got it's start in an attempt to model meteorology. Insights from mathematical analysis of that attempt revealed that any attempt to predict weather suffered from a sensitive dependence on initial conditions. Ever hear of the butterfly flapping it's wings thing? That has a sound mathematical grounding in Chaos Theory. The bottom line is, it has been proven mathematically impossible to accurately predict the weather. Climate is also chaotic, although over longer time scales.

The mass of ignorant people, who believe what they are told, who influence the politicians, and the media, who influence grant fundings, are the source of "global warming." Any scientist who really in his heart believes in global warming is either a fool or a charlatan. Any "scientist" who accepts a theory before it has survived the testing of the scientific method, is a [female of the species selling it for money]

Where has science gone? Probably the same path free speech followed in the quest of political correctness.

Would you trust a software engineer to build a bridge?

Give me a break here. You trust software engineers every time you drive across a bridge. The structural engineers enter the parameters into the program written by a software engineer. He gets the outputs from the program and specs the steel and rivets. Then you drive across it. You better trust these guys...or, program your magellan to look for ferrys and good "fording points"...

A Voice in the Wilderness

Very refreshing...someone who actually applies basic scientific principles to this propaganda campaign.

One of my biggest problems with this whole media campaign is, remember the scientific method? Is a theory proved by "consensus?" If so, then the sun revolves around the earth. And, electroshock is good for you. And, drinking liquid mercury is good for what ails you. There is a reason a theory must be proved through experimentation. All the scientists in the early 1800s who disagreed died because they drank liquid mercury.

My personal opinion is, barring the inherent feedback mechanisms the the chaotic inherently unsolvable equations determining climate and weather, is that we are in much more danger of entering an ice age. Climatic temperature shows a close correlation with sunspot cycles (translate solar output, the heat source, the sun is a variable star) and there are some very disturbing signs that we are entering what is known as a "Maunder Minimum."

Elastic Scattering

The carbon nanotube has the highest tensile strength of any material yet fabricated by mankind. Unlike Kevlar, the strategy discussed in this article (did anyone read the source article) is to elastically store the kinetic energy of the incoming round, and then to return the energy to the bullet. A kevlar vest absorbs energy in the breaking fibers and requires multiple layers to prevent penetration. The layers that do not break transmit the remaining energy of the round to the body, painfully, but over a large enough surface area that ideally penetration does not occur.

A couple of interesting things. The energy not returned to the bullet is dissipated along the length of the nanotube fiber, not at right angles to it. This has to be a good thing. Also, has anyone considered the inherent karmic justice of a bulletproof vest that return the projectile to the shooter at significant ballistic velocities?

As far as conservation of momentum goes, guys, little common sense here, if a guy can fire the gun and not be thrown backwards, the smaller rebound velocity will probably be manageable for the victims body.
