killing time with travel, technology & land rovers…

Trivia seems like a poor description….

There are 2*(10^11) to 4*(10^11) i.e. upto 400,000,000,000 stars in the Milky Way Galaxy (that’s four hundred-billion, using the short scale). That’s our local neighborhood.

The Milky Way is part of the “Local Group” of around 30 galaxies, and is the second largest, after the Andromeda Galaxy (10^12 – 1 trillion stars).

This group in turn, is part of the “Virgo Cluster“, which comprises of 1,300 to 2,000 galaxies.

The Virgo Cluster, is the heart of the “Virgo Supercluster“, which contains at least 100 galaxy groups and clusters.

There are millions of superclusters in the observable universe.

Amazing. Now I don’t feel so bad about not getting my chores done, even if the universe is just a giant computer!

Podcast: Can Geoengineering Save the Planet? – ScienceNOW

SAN DIEGO – Geoengineering has been a hot topic at this year’s annual meeting of the American Association for the Advancement of Science (which publishes ScienceNOW). Science reporter Eli Kintisch chatted with Ken Caldeira, a geochemist at the Carnegie Institution for Science in Stanford, California, about the latest efforts to cool the world – and the possible risks of doing so. Listen to their conversation here and read Eli’s full write-up on the topic here.

So, here’s some real information on geoengineering. The chemtrail folks would do well to listen!

Protesting for the sake of it

Just outside the San Diego Convention Center, which was the base of the 2010 American Association for the Advancement of Science conference (#AAAS2010), I passed a small group of protesters with various placards and in general looking a little disorganized, but as I like to keep an open mind I though I should stop and chat.
It turns out that it’s an anti-geoengineering rally (though there are more letters in the word “geoengineering” than protesters). The focus was on contrails, which according to the lady I spoke with are a part of a vast governmental/corporate program to affect the climate, so we don’t have to bother with lowering emissions – but the biological side-effects are terrible! I later discovered that wikipedia outlines this “chemtrails” conspiracy: http://en.wikipedia.org/wiki/Chemtrail_conspiracy_theory

Curious, and not being one to dismiss seemingly crazy suggestions out of hand, I tried to engage further, but it really just descended into a rant at this point. In the box of protest materials were “information” sheets concerning things people like to protest about – vaccinations, contrails, nuclear power, cars, etc. Clearly, rent-a-protest. She wouldn’t or couldn’t answer any of my (very polite and charming, and not condescending) questions about the science behind their claims. ScienceNow also picked up on this mini-protest: http://news.sciencemag.org/sciencenow/2010/02/smattering-of-activists-protest.html

Why do people do this? If they want to say “be careful with geoengineering”, then say that. State why, and people will be polite enough to listen. If you’re ranting then you’re going to be ignored. We know science isn’t perfect, but at least scientists attempt to communicate with the general public. Protesters really have a duty to become informed and stop spreading disinformation and downright lies. We have enough things back in the real world to worry about.
