Secret code

Here's a quickie, but it's too good to pass up.

A group of investigators found a rare species of shrimp that can communicate with circularly polarized light. Science News talks about it here. It's essentially like a highly protected code since this is currently thought to be unique to this shrimp. Of course now that it has been demonstrated with this little guy, it might provide clues to finding it in other animals, but given what is currently known it will be exceedingly rare if it is found in any other animals. This falls in the category of something so cool you could never make this stuff up.

Vorpal Sword +5

If you are a true geek, then you already know what this post is about from the title.

For the rest of you, Gary Gygax died a little over a week ago. He co-created the infamous role playing game 'Dungeons and Dragons'. There are a number of interesting pieces on him in Wired, the New York Times, Slate and others. These articles do him more justice than I will and honestly I can't claim to know anything about him. But this is the point where the routine confession emerges: yes I was a a D&D junkie for a while.

Here's my attempt at a profound observation about Gygax and D&D. He realized you were a nerd before you did. That is, D&D and its ilk became this road map for giving some young kid the chance to indulge their inner nerd while also learning to accept and understand this intriguing social and mental predisposition, and finally to create a game that would seamlessly have you network with others who had the same geeky tendencies.

Yes, some unsuspecting kid (actually not me, believe it or not, but I saw it - and you saw it too), who like everybody else was already dealing with the early onset of puberty but who had something even more sinister going on that they had not begun to deal with. We are talking of course about a kid who had still not recognized much less sought counseling for his inner nerd, but who would invariably discover D&D and, upon realizing its sheer awesomeness, would careen into school proclaiming its wonders to all schoolmates. This would be the first experience of coming to understand that one was slightly different from the other kids. It would also immediately help to thin out and narrow down the pool of potential friends to those with compatible interests. Notice the gender neutrality - this is important - girls and guys were sucked into this in healthy numbers because both girls and guys can be sheer geeks and that's the only real criterion here. Before you know it, this kid is trolling the halls with a pack of likeminded prorgramming, tolkien-obsessed types trying to find a DM (look it up).

It truly took a genius to give us 4-, 9-,12-, and 20-sided die with which to determine outcomes of situations with ogres, dragons, wizards and much, much more. I remember some nights looking at those dies totally transfixed by their symmetry and wondering how the hell they did that. Later in life I'm pretty good at 3D visualization and decent at recognizing symmetry - I've often wondered if those stupors in which I tried to figure out those cursed die had anything to do with that.

When Atari was exploding pervasively on the scene, when cable TV was the most amazing thing ever imagined on TV (after your Atari game player - will you ever get your revenge YAR?!?!?!?), Gary Gygax had the guts to make using your imagination cool and to create a way for people to get together with friends and challenge each other in mind games. It was brilliant.

The world this morning

In today's update I started to think about what happened to the fellow from several weeks ago who has a seemingly miraculous generator. Haven't heard anything since. This of course can only mean that it's being suppressed, man! But here's a guy with a fun idea for perpetual power - at least two easy reasons why it can't work. I'll save them for another post - I just don't have space in the margins provided here.

Looking for more ways to save the world? So are we! Not easy. I've gotten a little pessimistic recently. If you want to get into social justice by buying fair trade products, unfortunately you're best off doing it through charitable organizations (churches, student groups, etc.) since popular outlets just can't resist price gouging on these products since they have become "hip" and "trendy". Will this change? No idea.

More people are starting to bring their own cloth bags to grocery stores and so on. I think that's really cool.

A long, long time ago I heard about a study that showed scientists had a higher percentage who maintained religious beliefs/practices than other professional groups. I wanted to go looking for that study but couldn't find it. An apparently more recent study reported in an article at physorg.com finds that scientists have a lower percentage who practice or maintain religious beliefs compared to the general population, but finds that there are many misconceptions about religious beliefs in academia. Of course something about this study already raises suspicion for me - it only polled "21 elite universities". Who decides this, and what about the thousands of other universities in the country who weren't included in this study? Although the response rate was high - the sampling scope was breathtakingly narrow. And somehow the physorg.com article manages to use the word "elite" with an oddly sinister tone. So I say "thank you" to physorg.com for encouraging your readers to mistrust and be suspicious of higher education. Thank you.

Ode to a thumb

Did you know you have lots of nerves at your fingertip? Of course - but if you ever want to be REALLY sure that they are there, just skin your thumb really good (think on the level of an ER visit) and then try to keep your mind off of it. Oh treacherous thumb, I love and hate thee.

OK, the point of the post was to take my mind off of the throbbing. I can always count on the wickedly awesome thinkgeek.com to brighten my day with genius products like this backpack: keep your things safe it will or this totally unbeleivable laser game that I wish I thought of.

Fermat famously bragged in the margins of one of his notebooks that he knew an elegant proof to the theorem which now bears his name, but didn't have the space to write it out. Well, I'm no Fermat because he was scary smart, but I've been sitting on an idea for a heat engine that generates power directly and which might fit in the palm of your hand. It would have decent efficiency I think and it's really simple and cool but I just don't have the space to describe it here.

You gotta love the brits.

For a little fun chemistry, check out what you can do with supersaturated solutions. I don't like calling it 'hot ice' because that dumbs it down too much, but cheers for a good video. I could probably show this in my class actually. Hmmmm.
