Yup, that's pretty much exactly it.
This is as exciting as superluminal neutrinos. The sexy thing is that this actually exists :D

I had an introductory astronomy course, so all in all I'm not too familiar with stellar models beyond the basics... But there are many technical as well as practical difficulties I would think when you would try to determine the mass of the sun accurately enough to estimate G (even if you ignore that the model itself depends on G). One I can think of is the fact that stars lose mass throughout their lives, so we would need to know the age of the sun in the same order of precision, which is impossible.
But probably there are models for the trajectories of the planets, given a star with a slightly decreasing mass but I doubt that they would be accurate enough for comparison with our present situation.

Age of stars, to my knowledge, are actually estimated through their spectral emissions. E.g. a young red dwarf has different spectra than an old red dwarf.

That is correct. But determining the age to a accuracy good enough to make corrections to the known value of G? I don't think that is possible.

This is really the same thing as guessing one's person age looking at his face. You can almost always guess at what point of its life the star is, but not figure out the exact age with sufficient accuracy.

There were times when Rik and I were writing together when we almost died laughing. They were some of the most carefree stupid days I ever had, and I feel privileged to have shared them with him. And now he's died for real. Without me. Selfish bastard.

It's a Blue Parrot Fish. They have kinda beak-like mouths, and feed off coral and algae they scrape off of rocks with it.

Being out of the water does not allow its patterns to really shine.





As you can see, underwater, they don't look as blue as a whole. The X-grid pattern makes for some pretty good camouflage.

Wow, earthquake in Pakistan creates a new island:

http://www.emirates247.com/pakistan-earthquake-latest-death-toll-reaches-327-new-island-created-2013-09-24-1.522199

Can you imagine what kind of stories would have come out of this event 2,000 years ago? Shaking earth, flooding, hundreds dead, island appears from nowhere out of water.

What could they possibly do about this now? Scary stuff when you think about it.

Cynicism gets a bad rep.  It's associated with cranky and grumpy, and doesn't get recognized for its value in finding truth.

It still amazes me sometimes how these things literally go around the world.

Anyway, back on topic:
Next week some people from the VUB are coming to talk about the nobel prize in physics at our university, should be cool. Sadly Englert probably won't be there though.

There is a theory that a butterfly is not just transformed from the pupa, but actually created from the dissolved matter of the liquefied pupa's remains.  A separate DNA sequence assembles the butterfly from these remains.

I can't tell if I'm incredibly ignorant of biology, and simply too enamored with this idea to see how ridiculous it is, or if this does actually seem like a plausible theory.  At the end of the article is mention of scientific criticism of this theory.
