The more I study physics, the deeper I fall into its grip and the bigger the questions become. If I were a scientist I would be a physicist like my father. Physics, in all its phases, on all scales, is on the brink of some amazing discoveries.
In education, I firmly believe in Physics First. Not that I really believe in education. I don't think it's possible. The only educatiom is self-education. To that end all education must point, and the sooner the better.
If I designed a curriculum for kids it would include - physics, nature studies (trees, rocks, plants, etc.), writing (which requires reading), personal finance (as necessary as basic literacy) and drawing (which involves design). That's it, that's enough. Kids will figure out the rest all on their own with no help needed. For example - you need to teach a kid to use a computer these days? Obviously not.
I might include music, but no one should be the least encouraged to become a musician (or worse yet, an actor). That's just more trouble that they can figure out on their own. I see the swarms outside the Berklee College of Music every day.
Speaking of which, I just noticed that I did a Nile Rodgers set on Radio Roofscape. Sometimes these things slip by me. I can take a break from string theory by programming Chic or watching Quiet Desperation and remember nothing. In the case of Quiet D, much as I love it, that's a blessing of course. I'm a huge fan of Nile's B Movie Matinee. The guitar work is beyond crazy. Both hugely guilty pleasures.
Speaking of which, Lady Gaga is on Twitpic. Generally looking like her slutish self. Now that girl cries out to be on Quiet Desperation. Or maybe she is and I just didn't recognize her in that rolling freak show. What makes that girl tick I couldn't even begin to guess. But whatever it is it must be very tightly wound. I read the Rolling Stone interview and she's surprisingly intelligent (as she says, "you seem surprised"). What did come across is that loyalty to and the support of her friends (the Haus) was one of the most important things in her life. Well, that can carry you far. And it's good to see.
I've never lived in a place with so many crows. I haven't yet seen a single hawk, but the crows are all over. And noisy, kicking up a ruckus like a haunted house of rusty hinges.
Sunday morning. Kicked back in bed, iBook in lap, writing. Resting up for a big busy week. Thinking my thoughts. Thinking things over. And here's one of them. I have a huge decision to make.
But the hell with that. I just discovered a dozen pictures from yesterday that I hadn't even downloaded from the camera. Everything drops for photography. It's not even funny. The world stops. Image of Our Lady of the Streets, taken at St. Kevin's. She has a very large, and rather happy looking or maybe just leering, serpent snaking around her feet with various offerings of dead flowers, burned out candles and rosaries down below. That and more virgins.
Here's the decision. I have to figure out whether to keep Roofscape Magazine going or shut it down and just focus on the Roofscape Journal (which you're reading now), using Google as the platform for all future work. The magazine has been abandoned for awhile now, since I moved, but Journal is constantly being updated. At the least there's a new image every day.
Finished programming the Nile Rodger's set. He's such a musical genius. Wiki says that he has an autobiography coming out this year or next. Now that should be an interesting read. This is a man who's known and worked with everybody. He started out touring with the Sesame Street band then worked in the house band at the Apollo Theatre. What an education! I've read interviews with him and some crazy shit went down in his long career, as you might imagine. I'm a total freak (Le Freak) for musician biographies. Keith is supposed to be dropping soon too. Now talk about interesting. Plus it will be a chance to tell my Keith story. Here's a cut from B-Movie Matinee (1985).
This is such a great video too. When it ends, check out State Your Mind, perhaps an even more slammin' track from B-Movie.
OK, I'm going to tell my Keith Richards story. I've got nothing else to write about at the moment (well there is string theory, but I've currently lost the thread on that) and I feel like writing to avoid the dire necessity of doing any actual work. It is Sunday after all.
It was New Year's Eve. Josiah (One Take, Jo, Teddy, Theodore) Kinlock and I were in New York City. Jo's buddy Gwen Guthrie, the great R&B, soul and disco singer-songwriter (Ain't Nothin' Goin' On But the Rent) picked us up in a white stretch limo that could probably have swallowed about a dozen Smart Cars without burping. I hadn't a clue where we were headed and couldn't care.
Jo, of course, is being crazy, doing a rastaman routine, and keeping everyone convulsed. Sitting up front while I'm in back between Gwen and her equally ample backup singer. As Jo cracks them up I'm getting crushed. But enjoying it.
We head to the upper East Side and pull up in front of a building decorated like an Egyptian, or maybe Etruscan, tomb. For a party at Jellybean Benitez's (all of Madonna's first big hits, Whitney Houston, etc.). I'm sitting next to this really attractive blond who's being hustled on the left by a gorgeous boy toy and on the right by some music biz slimeball. And she's into #2. I'm laughing my head off hearing his stupid shit. When I catch up with Jo he tells me that was Debby Harry (Blondie).
We head downtown. Gwen's scheduled to do a track date at World, I think it was called, a club in the meat packing district (although my New York savvy is sort of shaky). On the way go into a building along Broadway.
We get in the elevator. A voice calls out, "hold the lift there mate", and Keith Richards steps in with the biggest bottle of Moet-Chandon that I've ever seen before or since.
I'm struck absolutely dumb, but my friend Jo doesn't miss a beat and begins chatting Keith up while his eyes take a stroll over Gwen's ample physique. 'Cause you know Keith likes him some large black girl singers (Sarah Dash from LaBelle). So he figures we're heading to the same party and as the door opens says, "let's go". And believe me, when Keith says to you let's go - you go. Wherever. Hell and back.
... More later.

Calabi-Yau Space . 2 | Starscape
This article is being written as your read. Patience please.
So, as we mentioned, string theory, a possible heavy-weight contender for a theory of everything (TOE) in the universe, requires 6 or 7 (depending on the flavor of the theory) extra dimensions to work. But where are they? And are those where our lost socks are languishing?
The answer offered by string theorists is that the hidden dimensions are everywhere but very, very small. Small on the order of the Planck length perhaps - 1.6 x 10 -35 meters - the smallest possible distance in the universe, as derived from various known natural constants such as the speed of light and strength of gravity. This is more orders of magnitude (powers of 10) smaller than an atomic nucleus is to a human body (by roughly 15 times, depending on your height). Small way beyond our powers of personal detection or most powerful machines.
These different dimensions in which strings vibrate are thought to be curled up at every point in space in complex geometric spaces called Calabi-Yau Manifolds.

Calabi-Yau Space | Starscape
Isn't this a strange and beautful picture? It looks sort of like a sphere swirling with mobius strips. This is a Calabi-Yau Space, a complex geometrical structure that just may hold the secrets of the universe on its twistng folds.
The overarching project of modern physics is to find a unified theory of nature, one that unites the four basic forces - electromagnetism, the strong and weak nuclear forces and gravity with the zoo of particles and their interactions described by what's known as the standard model of physics. One of the candidates for this vast and subtle task is string theory.
String theory posits that at its most fundamental level the stuff of the universe, quarks and electrons, is composed entirely of tiny 1-dimensional vibrating strings of energy. To harmonize with the largely proven standard model the theory requires the existence of 10, or maybe 11, dimensions, 6 or 7 more beyond the familiar 4, the 3 of space and 1 of time. Well fine, but where are they?

I'm not sure I even like this image. But I'm going to leave it in because someone might and it's not totally bad. You can never tell what people will respond or not respond to. It's always a surprise.
Be sure to read the article in Monday's New York Times, A Scientist Takes on Gravity. Gravity may not be one of the fundamental four forces of the universe, but just an 'emergent property', an afterthought. The universe just keeps getting weirder. Now that's entropy, right?
You can actually read the paper that prompted the article On the Origin of Gravity and the Laws of Newton by Eric Verlinde. Click on the title to go to its download page. The first few pages are comprehensible - and quite startling. I wish my dad, a physicist, was alive. He'd revel in this new age of physics, string theory, etc. On the other hand. he'd probably be quite skeptical, and rightly so. He was an experimentalist and all of this stuff is, not even theory, speculation. Peering unseeing into a vast dark - dark holes, dark matter, dark energy.

Wait a second ... didn't this quote just appear recently, and attributed to Aesop?
