It will be simple enough so that CMB experts can understand it but maybe no simpler unfortunately for everyone else.Joseph Smidthttps://www.blogger.com/profile/02583891162785742138noreply@blogger.comtag:blogger.com,1999:blog-4212234230338648875.post-20438281947120023732010-12-30T06:21:16.555-08:002010-12-30T06:21:16.555-08:00JS,

I deal with numbers that make profits and losses and I am always faced with difficulties in determining what is real and what is fake, as well degrees of uncertainty. Ultimately, I have to depend on my simulations (thanks, Nick!) done previously, on like kinds. Fairly complex, and not explainable.Ancient1noreply@blogger.comtag:blogger.com,1999:blog-4212234230338648875.post-7605887980441739352010-12-28T12:44:50.852-08:002010-12-28T12:44:50.852-08:00Nick,

So if their final results agree a lot of trust can be put into those results.<br /><br />As for CMB stuff, fortunately there are many competing experiments looking at a wide variety of things so if we get consistant results across the board this will be very reassuring indeed.Joseph Smidthttps://www.blogger.com/profile/02583891162785742138noreply@blogger.comtag:blogger.com,1999:blog-4212234230338648875.post-81579282448123819232010-12-28T09:46:58.165-08:002010-12-28T09:46:58.165-08:00This sort of thing is also a very big deal in exop...This sort of thing is also a very big deal in exoplanet searches where the signal of an Earth-like planet passing in front of a sun-like star produces a 0.001% change in the brightness of the star. With things like thermal expansion of the space-craft, star spots, dust, cosmic rays, etc. it takes a brave science team to turn the raw data into discoveries of exoplanets. <br /><br />I much prefer simulations where we know our results are untrustworthy at those levels of precision. It saves a lot of headaches.Anonymoushttps://www.blogger.com/profile/17367937708444729356noreply@blogger.com
