[QUOTE="Umbran, post: 6383688, member: 177"] I think of Eagleworks as the physical equivalent of Fermi estimation. It is by no means a full calculation with four part harmony and feeling, but you can still use it as a guideline. Let us note that Eagleworks is by no means the only people who claim to have gotten results from the setup. A group in China, if I recall correctly, claimed to get a result orders of magnitude larger than Eagleworks did, if I recall correctly. But, that result (r at least the reporting of it to the science community in the rest of the world) also lacked rigor. So, say you are NASA. You hear the Chinese claim a result. They don't turn over data. You have three choices: 1) Ignore the Chinese entirely. 2) Put theoreticians and thorough and expensive experimentalists on a deep analysis for years - and remember that Clarke's First Law applies* 3) Hand some chump change to someone to see if they can replicate the result, quick and dirty. In terms of risk analysis, tossing chump change at fast and dirty projects may make sense, as a cost-effective vetting process. You don't actually expect any of these to turn out results, but if one does... the return on that investment will be *huge*. Take it sort of as... NASA playing the lottery with pocket change. It does tend to churn up media attention. I don't see that as a bad thing, really. NASA has a problem that Congress won't back a solid mission plan. But vision and inspiration for new STEM students is a major payoff of NASA - normally, this is accomplished with the big missions that they now don't have. If they can't do it with the big money, they can try with the tiny money. I'm okay with that. Kids today won't care in five years if that result turned out to be nothing. Their imaginations and passions will be stirred into study anyway! [SIZE=1]* "When a distinguished but elderly scientist states that something is possible, he is almost certainly right.
