so only for very small black holes would this radiation be significant. Still, the effect is theoretically very interesting, and folks"... " However, the total lifetime of a black hole of M solar masses works out to be

Mmm some actual research as opposed to crapping from memory http://casa.colorado.edu/~ajsh/hawk.html "Hawking radiation has a blackbody (Planck) spectrum with a temperature T given by
kT = hbar g / (2 pi c) = hbar c / (4 pi rs) "
looks like some formatting has been lost
"- the hawking radiation is also 'useful energy', by definition of low entropy." if that statement is true you might be more right than me but the "by definition" looks dodgy
"Doesn't this make, in some sense, an ultimate matter --> energy converter" yes - but the release process can take a long time
"it seems to me that this violates entropy in some fashion," No it doesn't the hawking radiation is effectively (expected to be) white noise, the input matter is organised - entropy has increased
"Disregarding the fact that creating and maintaining a blackhole itself would require superscience" Maintaining a blackhole is easy - feed it matter at approximately the rate it is radiating (the e-mc2 thing) and it will be good for longer than any race may want to live, even without the input. Correct creating a non-trivial blackhole requires manipulating at least stellar quantities of matter - the smaller they are the faster they (are expected to) evaporate.
" hole, the energy from the Black hole is converted into simple hydrogen" Doing this without significant losses requires the superscience you mention
Because The Rolling Stones have exercised their intellectual property rights over the concept of painting anything black and the US military couldn't offer enough cash to get the Mick & Keith to pay attention.
Do the binder of crap and give it back to the people who did it and say you to do your job from this for a day.
You go get it back next day - marked up with all the bits they missed.
Redo it. Give it back a week later. After 5 or 6 months - it will be a good document.
Do this with all the low level employees first in every dept.
It doesn't matter how you get the first pass - just get it and give it back to them and have them work there job for a day from it, once every so often.
1) General Relativity as formulated by Einstein (and a lot of other similar derivates - are there many?) would be in serious doubt. An exam question I had was take GR and show gravity waves exist - you basically show how the wave equation falls out of the formulas and these things carry momentum out of a system.
2) You then need to explain stuff such as Mercury's orbit precession and observed effects of double Neutron stars slowing down - the FSM stirring his planetary meatball lunch slower?

Get in your ship from techno-ish city (London) and set sail for the Indies. Funny how when you get there everything is not quite what you might expect - think many worlds interpretaion co-existing. As the information flow speeds up - the realities converge - to what though?

The problem is that building a massive database is possible.
The disk space and processing requirements are possible. Examples - archive.org and CERN's efforts for data processing on the LHC.
Getting the data is the hard part at the moment.
Maybe the model you suggested taking pictures is the way to go. [Can I have a redhead instead?]
So we should cut off everbody but a few selected leaders access to money and source code because they have the skill and ethics to handle it?
And knowledge - don't want anyone learning physics and building weapons.
It's a bit late now to be worried the power some will have - they will get it, the question is how to counterbalance it. Like you I am not real thrilled with the idea of MAD in everybodies hands - but what other alternatives are there?
By binding potential developers (and we will may never see what is in the agreement in total) to MS it may make it a lot harder for them to deliver products that work with linux.
Now everytime they go to release a driver legal are going to have to have a good hard look at driver and the MS agreement.
How long before it gets to be too much hard work and they not bother?
"developers, developers, developers" is still true. Without delivery of new products any OS will die. Kyocera Mita make stuff people want to use in business settings - printer/fax machines and stuff like that.
I can't comment on your combinatorics as I hate that as a subject. But I have no reason to doubt. Once I can work out how to tackle the question it is straightforward. It is getting the math setup right that screws me.
I would just expect 144/45 of each number to be there - that may be the lazy physicist in me.
I used to work a lot with statistics and I know I don't like them.
One of my rules (possibly stolen from someone): statistics are easy to calculate but hard to interpret.
Once upon a time when I cared more about the numbers I wrote a small Basic (Qbasic I think) program that gave spat out as many games as I wanted covering all the numbers - guaranteed. How easy - it wasn't guaranteed to terminate, it just kept iterating until it did.
Down here in Australia - the quick picks are a real gamble - they might or might not do what you say, but I do know they don't always cover every number.
This Saturday night is a $30m draw and I just bought my ticket out of here for fun and maybe profit. I haven't checked, but have had these tickets before and I know that even with 144 (24*6) numbers you don't always end up with at least one of every 45 available.
The benchmark I worked to was that anything that did 100MFlops or more was a supercomputer - I didn't buy a PC for myself until i could get a supercomputer - a PII 400Mhz (2nd hand and it cost cash more than the machine I bought piecewise and assembled last year)

You know in some countries work related tax deductions are allowed.
How many did you need and can you afford to pay for while you wait for the tax refund?
