BOMBS AWAY!

LCROSS Centaur Separation occurred at 9:50 p.m. EDT (6:50 p.m. PDT), Oct. 8. After separation, the spacecraft performed a 180 degree pitch maneuver (turning around) to reorient the LCROSS science payload towards the receding Centaur.

This is going to be so great!

BBC reports on simulations run by astronomers suggesting we could see some planets collide in a billion years or so.

What’s fun is that you can actually ATTEMPT to run these computations in Wolfram|Alpha.  Here’s mercury in 1 billion years. Unfortunately the one thing I want to be able to show is the orbits of the planets and that is pushing W|A to the heuristic timing limit.

I can put this into Mathematica and work it out using more local CPU power.  Then again, I like just playing with numbers to see where I can take this.  Here’s Mercury at 199,999 years.  Things get gnarly.

In the 6th edition of “On the Origin of Species” Charles Darwin lamented over the power of “steady misrepresentation” of the facts and observations of his work 150 years ago. Those were days when God’s grace meant you could be hanged for opposing what everyone knows was the “WORD”.

While there has been a steady diet of multidisciplinary science that continues to support, extend and find nuances of his findings on natural selection, genetic drift, mutation and speciation, there is, and will always be groups that obfuscate the information in favor of their own approach to origins of life and man in particular.

As authors Glenn Branch and Eugenie C. Scott have laid out in their review in the recent Scientific American, these various miscreants of misinformation; these groups or people that have no science, no peer review, no database of exceptions, no body of anecdotal evidence to support their views also have no conflicting data points they can point to in support of their views. In fact, their approach is not about science, evidence, methodology or technology. It is about “faith in dogma” and it is shared by millions of people around the globe.

The real pariah in the whole mess is the body of people that take a “live and let live” approach. You know who they are… “Hey, as long as they don’t make me kiss a ring, they can do what they want in Rome.” These are the people who traffic in ambivalence. They too will always be with us. They sit on a fence, not necessarily supporting dogma and yet the view that man is a kin of other primates, that our hiccup reflex is a remnant of our fish history, or that we have to deal with the almost two dozen versions of extinct humans (Viktor Deak) is just upsetting enough, if not unconventionally disturbing for them to ignore. (As if prayer for soldiers being shot at isn’t or holy wars where millions have died are somehow, in comparison, OK.)

Remember Galileo who was convicted of suspicion of heresy for following the position of Copernicus which went contrary to that laid down by the Roman Catholic Church authority of Holy Scripture.  All of this today is still about the dogma of faith vs. data of science. Same stuff, different year.

There have been crusades, ethnic cleansing and the other stuff that made up the Dark Ages. And here we are in the Spring of 2009 reviewing our civilization and thwarted by those who don’t want people to figure out what the heck is going on out there.

Enter Governor Bobby Jindal who is a potential presidential hopeful of those currently out of favor in US politics. In 2008 he literally signed the Louisiana Science Education Act into law.

Marketed as supporting critical thinking in classrooms, the law threatens to open the door for the teaching of creationism and for scientifically unwarranted critiques of evolution in public school science classes [in Louisiana].

(Branch and Scott, 2009)

Does it sometimes seem to you that, while we may have evolved, there are some that didn’t get the memo? Next FOX News will be telling me that Mike Huckabee, former Presidential hopeful (who believes in the literal and biblical interpretation of Genesis) will administer the plan.

Chezz!

I can’t remember if I posted about Stellarium before.  Sorry for a repost if I have.

Stellarium is one of the coolest open source projects out there.  In fact, I’m not sure how good a commercial version of this would actually be.  Some things are just better as academic and labor of love efforts.

If you like star gazing, deep space imaging, telescopes and generally “where are we in the universe” stuff, download this thing and play with it.
