OK, let's squash some of this nonsense right now.

I never believed the 2010 Haiti Erthquake was caused by a voodoo curse, and I'm astonished that anyone interpreted that post in that way. What I found anthropologically interesting is that something like Robertson's "satanic" invocation seems actually to have taken place. Not actually "satanic", but within Robertson's impoverished terms of reference that's about the only way he could describe an invocation of the loa.

I believe, and have repeatedly said, that the supposed "scientific consensus" on CAGW is not a conspiracy but an error cascade. I think most scientists are honestly trying to do right, but have been overly credulous about data and models that have been (and continue to be) fraudulently manipulated by a tiny minority of them. Those of you who think this makes me some sort of nut are going to have some explaining to do when measured GAT drops out of the bottom of the IPCC's 95% confidence band, which looks set to happen before the end of 2014.

I might reply to some of these other questions at more length, but these two deserved to be dispatched immediately

Comment Yes, Kuhn was almost perfectly wrong (Score 1) 265

Yes, Kuhn was full of horse puckey. Not only doesn't his book describe science outside of physics at all well, it doesn't even correctly describe 20th-century physics, its ostensible paradigm (using the word correctly now) case.

Years ago I wrote a more detailed takedown in Brother, can you Paradigm?

The only amplification I'd write today is that the shifts between large theoretical models generally (and contrary to Kuhn's claims) go smoothly in physics because test by correct prediction of experimental results is so difficult to argue with. The soft sciences have more trouble setting up repeatable experiments, so it's easier for people to hold on to broken theoretical models.

Man Uses Drake Equation To Explain Girlfriend Woes 538

artemis67 writes "A man studying in London has taken a mathematical equation that predicts the possibility of alien life in the universe to explain why he can't find a girlfriend. Peter Backus, a native of Seattle and PhD candidate and Teaching Fellow in the Department of Economics at the University of Warwick, near London, in his paper, 'Why I don't have a girlfriend: An application of the Drake Equation to love in the UK,' used math to estimate the number of potential girlfriends in the UK. In describing the paper on the university Web site he wrote 'the results are not encouraging. The probability of finding love in the UK is only about 100 times better than the probability of finding intelligent life in our galaxy.'"

Hydrogen peroxide powered rocket packs fly for around 30 seconds, because they have a specific impulse of around 125, meaning that one pound of propellant can make 125 pound-seconds of thrust, meaning that it takes about two pounds of propellant for every second you are in the air. Mass ratios are low for anything strapped to a human, so the exponential nature of the rocket equation can be safely ignored.

A pretty hot (both literally and figuratively) bipropellant rocket could manage about twice the specific impulse, and you could carry somewhat heavier tanks, but two minutes of flight on a rocket pack is probably about the upper limit with conventional propellants.

However, an actual jet pack that used atmospheric oxygen could have an Isp ten times higher, allowing theoretical flights of fifteen minutes or so. Here, it really is a matter of technical development, since jet engines have thrust to weight ratios too low to make it practical. There is movement on this technical front, but it will still take a while.

Comment Re:Problems with Ajax the article didn't mention (Score 1) 510

Nonsense. There is no reason to assume that the use of Ajax will break the MVC model, unless you implement it badly. The difference is that the page is making the HTTP request instead of the browser, but it is still just a request. Data is being passed to the server, the server processes, and data is passed back to the client. All of the controller and model code still reside on the server, Ajax doesn't make you implement such logic in the page.

Single query and single response? I fail to understand your point. Ajax doesn't support multiple simultaneous queries, nor does it support multiple simultaneous responses. It is still one request, one response. Its just a different type of request than POST/GET.

It's not the new year yet, but it seems like a good time to give thanks.

Long story short, I've had a good year. Great job, short commute, and dating again. I've become focused, but with great flexibility. I'm not sweating the big stuff, or the small stuff. The good stuff is in the middle.

May your holidays be commercial-free,
