There is much crowing about how this proves supersymmetry, etc., but then it fades from the general consciousness because it's hard to understand and has no obvious practical impact.<BR/>2) The LHC finds only the Higgs. This would be pretty awful from the point of view of high energy physics, and that awfulness may make for a compelling media story.<BR/>3) The LHC finds something really wild and exotic - this would be a big deal, and justifiably so.<BR/>4) The LHC finds nothing at all, not even the Higgs. This would surprise a lot of people, and again might have a compelling media narrative (picture the headlines now: "Nonexistence of 'God particle'?").Douglas Natelsonhttps://www.blogger.com/profile/13340091255404229559noreply@blogger.comtag:blogger.com,1999:blog-13869903.post-816933285345210582008-07-21T11:13:00.000-05:002008-07-21T11:13:00.000-05:00My guess is that once experiments actually start, ...My guess is that once experiments actually start, the news coverage will totally die off. How long will it take to interpret the data output of a single experiment on this thing? What member of the general populus is going to have the patience to continue to pay attention while that process happens? For that matter, how many people on the planet will truly be able to understand the results? The media will eventually get bored, when they realize we can't just hand them the secrets of the universe in a 30-second video clip.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-13869903.post-38346113608842441972008-07-20T17:02:00.000-05:002008-07-20T17:02:00.000-05:00If we want to brag about the coldest spot in the u...If we want to brag about the coldest spot in the universe, it's not in a dil fridge.

Depending on which ones are running, and which ones are leaking, at any moment in time, any one of them could be the coldest spot in the universe. Of course the thermometry and computer control of each is completely different, but it would seem feasible to have each dilution fridge send its current temperature to some central server, which can then pick the coldest and let the world know where the coldest spot in the universe is.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-13869903.post-2618488049606761542008-07-20T01:55:00.000-05:002008-07-20T01:55:00.000-05:00I think you need to take a breath, Doug. This is ...I think you need to take a breath, Doug. This is the general public we're talking about, and the wonder and awe they express at the things we scientists take for granted is perhaps even motivating in itself. It's easy to forget that we walk into a lab and play with toys colder than any temperature in the rest of the known universe, or with devices made from countable numbers of atoms, or that we fabricate these devices with beams of electrons ripped out from their host lattices by electromagnetic and thermal forces. If anything, we should take it as a good sign that they're paying attention! Even if the 'mysteries of the universe' uncovered are the little details which we find mystifying and they find mundane.jonahhttps://www.blogger.com/profile/00766485331481072213noreply@blogger.comtag:blogger.com,1999:blog-13869903.post-67119116484906110192008-07-19T11:08:00.000-05:002008-07-19T11:08:00.000-05:00Chad, I'm with you.

I also know that having weekly news stories for months on end before the machine is even turned on is excessive. As far as inspiring the young, I could make a reasonable argument that the significant majority of physicists do not work on particle experiment, and in fact in the future that ratio is likely to become even more lopsided.Douglas Natelsonhttps://www.blogger.com/profile/13340091255404229559noreply@blogger.comtag:blogger.com,1999:blog-13869903.post-43594471602269525532008-07-19T10:25:00.000-05:002008-07-19T10:25:00.000-05:00I don't see the problem or how they're being hyper...I don't see the problem or how they're being hyperbolic.<BR/><BR/>The LHC is quite possibly the most complex machine ever built.
