Seeing isn't always believing...


One of the reasons I love Phil Plait's Bad Astronomy website is because not only is he a brilliant astrnomer and movie buff, but he's a total geek and nerd of the highest order, which makes him OK in my book.

So, from his blog, please regard the image below:



I love optical illusions... in this image, you can see three embedded spirals... one is green, one is pinkish-orange, and one is blue... right? Wrong! In fact, the green and blue spirals are actually the same exact color! How cool is that? Don't believe me? Check out Phil's full entry for the complete explanation... it's worth it, trust me.

Astronomically good stuff, cheap!

I am an astronomy buff.  And as many of you know, 2009 is the International Year of Astronomy. Yay

So you can imagine my joy in learning of the initiative put forth by a group called galileoscope.org. This group is producing replicas of the telescope Galileo used to survey the heavens over 400 years ago. These telescopes, while by no means top of the line, will easily allow you to get a good look at the craters on the moon, Jupiter and its 4 largest moons, and the rings of Saturn. And the most amazing thing about them is the price: $15.00!  


I've read some comments on other blogs about the shipping costs being high, and some concern about their capabilities and how long it might take to get them. But for $15.00??? I'll take a shot. I bought 2: one for my (soon to be) 8 year old daughter, and one to donate to her school.

I urge any of you who have children and want a decent starter telescope at a ridiculously low cost to pick one of these up, and maybe get one to donate to your local school.

How bad journalism hurts science; the 'Darwinius Masillae' foofooraw

As you readers will come to find out, if you haven't figured it out already based on the description and first post of this blog, I am a proponent of reality.  I do not take comfort in abject devotion to imaginary sky fairies made up over 2ooo years ago by nomadic goat-herders from the middle-east. If those are your beliefs, so be it... more's the pity.  But I stopped believing in magic and fairy-tales when I was about 12.

So needless to say, I have a fairly obvious position in the debate over evolution vs. creationism.  Actually... as far as I'm concerned, there is no debate.  Evolution, as a scientific theory, has over 100 years of research and literally mountains of evidence supporting its premise.  It meets all the same criteria that any other widely accepted scientific theory, for example, Gravity, meets.  Creationism has no more supporting material than the Greek mythologies of the ancient world that we so easily dismiss now.  Yet somehow a large portion of the population still rejects evolution as an affront to their religious beliefs.  Someday we'll grow up as a race... but anyhow, I digress.  

The purpose for that preface was to give some background for this post.  Recently, a significant fossil discovery was released:  Darwinius Marsillae.  See the image below:

As you can see it's a spectacular fossil... I'm not an expert, so I'll leave it to PZ at Pharyngula to give you more of the details as to why this particular discovery is important.

The problem is not so much with anything in the discovery.  It's an important and relevant find.  The problem came with the media circus that surrounded the find, and the backlash from the religious / Creationist community.  Some of what follows comes from a comment I made at Pharyngula, so I apologize if any of this seems familiar: When the discovery was announced, the media went hyperbolic, and claims of "the missing link" being found were tossed about.  This, of course, made the science community cringe, because as any real scientist knows, "missing link" is a completely useless phrase.  There is no missing link.  There never will be.  The fossil record is quite definitive in the lineage that leads to homo sapiens.  No missing link is required.  Also, many media outlets reported that this discovery "proves Darwin was correct", or "proves evolution".  This could not be more laughable.  We have over 100 years of evidence, fossil records that show quite thoroughly that evolution is correct.  This fossil does little more than adds another piece, albeit a spectacular and significant piece, to that growing mountain of evidence.  

What the over-hyping of this find does is actually puts undue significance on an otherwise important find for the wrong reasons. And this is dangerous for the credibility of the science in the eyes of the layperson public.

So, the find is announced, and it is beautiful and stunning in its preservation, especially considering its age... but a frenzy-driven, revenue-conscious media gets a hold of the story, and a fame-grabbing "scientist" unleashes undue hyperbole, and terms like "missing link" get thrown around. This grabs the attention of the general public, many of whom are fence-sitters on the whole "evolution vs. creation" debate, mostly because all they know they get through the mass media. Unfortunately, after the initial awe of the first reports wear off, you start to have reactions from all sides. And in this case, all sides are reacting to the initial report fairly negatively. Scientists are reacting to the fact that this find, while significant, is simply another piece in the mountain of evidence for evolution, and doesn't in any way represent any "missing link". Creationists react negatively, as expected, dismissing the find as meaningless and using the same tactics they've used to try and ignore and discredit other significant finds. So there are all sides of the issue, all reacting negatively to the find, and all the general public hears is "this is no missing link"... and as a result, for many, this equates to a negative perspective on evolution, and becomes an easy item they can point to and say "well, they thought that fossil they found back in '09 was the missing link and it turned out to be nothing". Which is a complete mis-representation of the facts. All sides have problems with the way the story was presented by the media, but for completely different reasons.

Had the story been reported accurately, and hailed for what it was: a significant find that adds another piece to the evidence in the fossil record; then the science community would have nothing to complain about, and the Creation community wouldn't be getting its public exposure, while all up in arms. And what we'd be left with is a beautiful specimen ripe for study and discovery, which is really all we should be looking to get from Ida.
