Game On – The Shell Game

Many moons ago, or, to be more precise, just over seven years ago, during July and August of 2012, I started a little “game” based on the old encyclopedia game, but updated using Wikipedia. There’s a whole explanation, and video, on the original post over on my SaltShaker blog. I had good intentions, as it was just sort of a nice break from only writing about food and wine, but in the end, it only lasted for six posts, and then just passed into oblivion.

That has happened on and off again with writing ideas, like my thought two years ago to start a series of commentaries here on political stuff… which lasted exactly one post (the fallout from various friends after sharing it was just more wearying than it was worth). But I’m feeling in the need of a diversion again – this may only last a post or two, we shall see. I decided rather than picking up from the last post in the original game, to give Wikipedia another shot with a “random article” pick, and see where it led my thoughts.

So, the page it led me to this time was that of Dizoniopsis coppolae, a type of marine sea snail found in the Mediterranean (pictured above… very pretty, no?). Now, I could go on for a bit with various bits and pieces about sea snails, I have no doubt. And maybe even a recipe or two, which would probably be best suited back on the other blog, but I thought instead, I would head down the rabbit hole (the sea snail hole?) of the who, related to this snail. As the Wikipedia page notes, this snail was first described by “Aradas, 1870”. A bit of research leads me to one Andrea Aradas, of Catania, Sicily.

Sr. Aradas was a Sicilian zoologist, who had started out as a medical doctor, something his father, Fernando, pushed him into. I have no doubt that their were family squabbles aplenty when young Andrea headed down the path of researching and teaching about mollusks rather than staying the course of medicine. In the end, however, he was rather important in his field… Malacology… which we’ll come back to in a moment, having discovered and/or described numerous species over the years, amassing a huge collection of both live and dead specimens, along with a lot of research into prehistoric echinoderms, and in the end, creating Sicily’s first science museum, the Zoology Museum at the University of Catania, which still exists to this day, and donating his personal collection to the museum.

Now, most of you know I love words, and so, seeing a word I didn’t know, I immediately headed there. Malacology is a branch of invertebrate (no spine) zoology specializing in the study of mollusks. I had no idea that mollusks have the second most number of species that have been discovered of any phylum of animals, after arthropods (insects, which doesn’t surprise me as coming first). Mollusks include snails and slugs, clams (and presumably other bivalves), octopuses and squids. Those who study malacology are, not shockingly, called malacologists. I also learned that there’s a second term, not to be confused, which is Conchology (and, by connection, conchologists), which is the study of the shells of these same mollusks, but not the creatures themselves.

And that, was kind of where my random wanderings took me. I’m sure I could go on and keep going within this arena, but I will pick that up on the next installment, assuming there is one. Instead, I wanted to circle back to Andrea Aradas, who in addition to the dozens upon dozens of mollusks he first described, also has the distinction of having gotten to name, or had named after him, six particular species of mollusk. And since we started off with a pretty picture of shells, I thought it only fitting to finish off with those half dozen, as best I could figure out from online photos (and yes, I “lifted” these photos from various places on the internet)….

Aradasia Gray, 1850, today reclassified as Coralliophila inflata

 

Atrina aradasii, 1851, aka Pinna aradasii, though now reclassified as Atrina fragilis

 

Cernuella aradasii, 1842

 

Limopsis aradasii, 1842 – fossil remains

 

Murex aradasii, 1883

 

Pectunculus aradasii, 1842, which, I think, is this one, though hard to find, and appears to have been reclassified as Glycymeris violacescens

 

Whither goest this game next?

Hyperspace

“listen, there’s a hell of a good universe next door; lets go.” – e.e. cummings

I was going to claim that I now completely understand the theories of general and special relativity, quantum mechanics and superstrings and am now ready to formulate The Theory of Everything. It isn’t, however, quite true. On the other hand, after reading and thoroughly enjoying Michio Kaku’s book Hyperspace, I can at least claim to have a better understanding than what my college physics professors left me with. (To be fair, nobody was really talking about superstrings then, so I can’t really blame them for that part.)

The book is subtitled “A Scientific Odyssey Through Parallel Universes, Time Warps, and the 10th Dimension.”With all the news stories about black holes, wormholes, and holes in the fabric of space-time, I thought it was about time to find out just what the (w)hole hype was about. Kaku, who is a professor of Theoretical Physics at the City College of City University of New York, manages to take this intriguing and complex set of subjects and somehow make it all seem quite reasonable, really.

The book is clearly written for lay folk. You don’t need to be a rocket scientist, figuratively or literally, in order to follow him through fields of wavering quarks. Kaku has a warped sense of humor that he brings not only to his descriptions and demonstrations, but also swings around point-blank on the history, egos, secretiveness and pomposity that surrounds much of the work of theoretical physics.

Using a medium that is, for all practical purposes, two-dimensional, a sheet of paper and ink, he unfolds first one and then another dimension of space-time and lays it out for our inspection. By the time I finished the first section, “Entering the Fifth Dimension,” I not only felt I had a clear grasp, for the first time in my life, on the theories of relativity, but I was also using terms like “blue-shift,” “hyperdougnut” and “scalar particle”in polite conversation.

The one negative I found in the book was in the second section, “Unification in Ten Dimensions,”where Kaku slipped a bit on the layperson approach. For some of the quantum brambles that he wanders through, he seems to assume that the reader has a basic working knowledge of leptons, mu-neutrinos and just exactly what SU(N) symmetry is. I found myself a bit bogged down in flipping back and forth to short explanations in the endnotes (an anathema to any reader – footnotes are so much easier to refer to), and having to reread passages. If one were psychologically inclined, one might assume that Kaku doesn’t really like a lot of quantum theory….

Luckily, he jumps back in with both feet, a smile and a “how-de-do” when he gets to superstrings, black holes and the possibility of other universes in “Wormholes: Gateway to Another Universe?” Whether he’s talking time travel, the existence of God, wrinkles in space, or wave functions of creation, he’s back on solid ground, and so is the reader – which, given the subject matter, is a pretty impressive feat.

In the final section of the book, “Masters of Hyperspace,” Kaku looks at what our future might be. He takes us through Type 0 through Type II civilizations, and pegs us squarely in mid-0 position. He also takes the opportunity to philosophize and climb onto a well-reasoned soapbox about where we’re going to get if we stay on our current heading.

It’s hard to say that the book ends on a positive note, especially given that basically, he leaves us drifting within the boundaries of the universe, with only minimal theoretical hope for some sort of existence as it either expands and cools to absolute zero or collapses as one big multi-billion year flash-in-the-pan. Kaku leaves us a faint glimmer at the end of the hyperspace tunnel, that maybe, perhaps, we might just find our escape into another dimension. Rod Serling would like this guy.
