Well.... I would'nt be surprised if there is some tangible out of this whole business by 2010 . There is a huge DOE research project looking at sequestering Carbon dioxide from power plants and other big industries directly at source. Looking at how destructive the weather has been over the last year, this is not surprising. However, 25% of CO2 emissions are from automobiles and cannot be trapped. One of the advantages of shifting to Hydrogen is that, most of the CO2 emission will be taking place from a few locations and it will be easy to trap it and put it underground.
The government released $1.2 billion couple of years ago just into Hydrogen fuel research and the plan is to have someting tangible by 2015. However, looking at how the pressure is increasing - 2010 is probably not an impossible target to achieve.
For those interested, the Hydrogen road-map and other interesting stuff is available on the energy.gov and DOE webpages. Dont have the links on hand - Google them up:)
The new planet whips around the star in a mere two days, and is so close to the star's surface that its temperature probably tops 400 to 750 degrees Fahrenheit (200 to 400 degrees Celsius) oven-like temperatures far too hot for life as we know it.
The nice thing is, if it's size is twice the size of earth and its mass is about 8.0 times the mass of earth - then it has the same density as Earth does. So, probably it's inner structure and composition is similar to our own planet.
Now, if only we find another one of those which took a little longer to go around it's local sun, we could start worrying about carrying our towel with us wherever we go.
Like someone on the group mentioned, it makes a huge difference in codes using the FFT. I'm an engineering grad student working on Computational Physics. The difference between using a 4-decimal-place Pi value and probably a 15-decimal place Pi value is in the amount of error you generate when you do an FFT, followed by an inverse-FFT. With 4-decimal places, I guess your errors are of the order of 1e-5 or so as compared to machine-precision when you use about 15 decimal places. If you run some kind of a simulation, within a bunch of FFT, inverse-FFT cycles, the entire data would be corrupted if the value of Pi is not good enough.
Just my 2c, and yes - I've done that in the past:)
I dont know about cluster, but connecting a bunch of them together on ethernet or something sure sounds like a fun thing to do. I was looking at the ports that were provided behind the synth. Found nothing too exciting except for a bunch of USB ports for getting your data out.
It's not really a molecule. Molecules are "bonded" due to Chemistry(covalent bonds, sharing electrons and all that jazz). Clusters on the other hand are formed due to a need to minimise energy.
To my understanding, it's something like soap molecules in water which most of us would have learnt about at some stage. They have a spherical head part which loves water and a long tail which hates water. So, bunches of molecules form spherical "clusters" where all the tails are on the inside of the sphere, guarded from water by the heads on the outside.
Many substances form clusters (usually at low temperatures). Recently, Prof. Eugene Stanley and associates discovered that even Water forms these clusters at sufficiently low temperature.

Well, found a link to the NSF Press release.

Someone has to tell them :

4-decimal places !! that's it !!

Hmm .. I wonder if it was intentional, but your result is precise in arithmetic modulo 13 :)
42 base 13 = 4*13 + 2 = 54 = 9 times 6
