This took me an embarrassingly long time to come to grips with. I've studied a good deal of physics in high school and college (not majoring in it,...
Well, when "you believe" something, that needs to be supported with credible evidence. The same physics of CO2 that powers steel-cutting lasers also...
One can distill the difference to the following bite-sized philosophies: The Chinese perspective: the people who are most ethical and fit to lead...
Milankovitch cycles are generated from first principles, namely orbital mechanics and rigid body dynamics. They do not involve mass distribution...
Now I'm curious as to what the fastest OS/web browser combination is. There are some awful tiny Linux-based OS' out there, like Slax. It could be...
I would suppose that it's the cultural training of the people and their Confucian values, rather than about race per se. They simply decided to adopt...
I've been to relatively few places: Canada, Mexico, Japan, China/Taiwan, and Thailand. Eventually I would go to more places. I'm most interested in...
The two most prominent explanations are: 1. Heat left over from the planet's initial formation. Planetary accretion generates a tremendous...
I have the impression that Woody1 is making a genuine effort to understand the science. I'll address the OP directly: A 270ppm to 400ppm CO2...
In the middle of an engineering problem (fatigue modeling), I sought Gradshteyn and Ryzhik to solve the following: \int \limits_0^a x^\alpha...
I wonder what the maximum air speed is in clapping hands. The sound suggests that it is below sonic speed, but it comes close - my guess is Mach 0.90...
I recently wrote a short script in Matlab / Octave with the following pseudocode: 1. Initialize F, s, Δs, b, and n. 2. While s < b or F < 100,...
The process of recrystallization may cause intermetallic phases to form, which complicates any proposed one-step process. To find out the elements...
There are many more examples. Haven't you heard of all the improvements to steel? But people still use low-grade steel. It all comes down to price.
Sounds like #1 is the better option if you cannot detach the part. However heat decreases the strength of metals and it may be not the best option in...
This thread periodically gets polluted by a few low-quality posts. I don't think it would be worth it to post the multitude of papers in the last...
Ah yes, that's right, I forgot the minus sign. The correct expression for the 2-parameter Weibull distribution is \rm PDF(\it x) = \frac{\alpha...
Although CO2 is only 0.04 vol% in the atmosphere, it makes a big difference. If only we could see it: http://www.youtube.com/watch?v=81FHVrXgzuA...
As a good exercise, it should be noted that the 2-parameter Weibull distribution probability density function (PDF) \rm PDF(\it x\rm) =...
A good read. Didn't know about this history, maybe I missed it on Spencer Weart's website.
