Fraternal Twins going equally fast at all times?
he always promotes the demiurge of nettiquette, bottomposting with no indentation. anyways, the whole field of relativiy Depends (tm) upon Minkowski's goopy phase-space, and his silly slogan about it -- then, he died. well, like any one else, he put his pants on, one lightcone at a time! thus&so: well it's a... 25 Jun 2010 15:23

Lunaroleum BP launch with cap&trade "last bailout of Wall St."
well it's a good experiment, "coking" water and calcium carbonate to make these hydrocarbs "up to 20 carbons," but I misread the statement about "oil theory with currect [sic] genesis." presumably, the neologism indicates that the current "impact theory" of lunar genesis is neither here nor there nor correct, be... 2 Jul 2010 15:45

Signs of (Mathematical) Life
If I were to see a circle on the moon, I would not be surprised. Nor if I saw a straight line (line segment.) But if I saw a square should I call the newspapers? If I saw the first 1,000 prime numbers in binary I would definitely call the newspaper. What is the simplest sure sign of life? The most complex... 26 Jun 2010 14:07

JSH: posting is cruel
The string of text above is known as your Internet connection's "reverse DNS." The end of the string is probably a domain name related to your ISP. This will be common to all customers of this ISP. But the beginning of the string uniquely identifies your Internet connection. The question is: Is the beginning of... 25 Jun 2010 10:59

lines of force converging on three or more points (?)
This is inspired by lines of force in magnetic fields. We can take all circles C_r (1<=r<=2) which are in the upper half plane, are tangent to the x-axis at (0, 0) and where C_r has a radius of r. They all pass through origin (0, 0). If we remove the point at the origin, each C_r can be obtained through a c... 26 Jun 2010 05:27

Globally defined solutions.
Take a Cauchy problem like: y'=xsiny y(0)=y* Show that the problem has a unique solution globally defined on R. I'm having trouble with this type of questions: how does one prove global uniqueness? Only via the usual theorems? How does one show a solution is "globally" defined on R? Another example is ... 26 Jun 2010 09:44
