One egg, one basket
I've been working on physics on my own for almost a decade now. Mostly I just scribble away in my notepad, chasing one idea after another. In one sense, it's the most quixotic quest on the planet -- to figure out the geometric structure of the universe mathematically -- but it's the most worthwhile use of my time and brain I could think of. Ten years ago, as a graduate student, I saw the whole theoretical research community heading off to study string theory. Learning a bit about it, I thought strings to be kind of far-fetched. The theory is mathematically pretty and consistent, but it doesn't seem to naturally match up with the universe we inhabit. Mine is the minority view. String theory has become the dominant paradigm in high energy physics -- with almost all government funding and academic posts in fundamental physics going to string theorists. I left to work on my own physics, while the world went string crazy. But, over the last year, string critics have been gaining strength -- pointing out string theory's lack of predictions, lack of accountability, and the detachment and even disdain for anything as mundane as our standard model of particles.

This backlash against strings has recently led to an interesting development. A private foundation has been created to support and fund foundational physics research in areas other than string theory:

fqxi.org

They gathered a few million dollars in seed funding, and they put out a request for proposals from researchers around the world. I couldn't ask for a better opportunity than this. Along with 172 other applicants, I gathered up my best work and submitted an initial proposal. Happily, this was accepted and I, along with 50 others, was invited to submit a full proposal. I did the best job I could of describing my work -- essentially, a geometric alternative to string theory that unifies gravity and the standard model of particle physics -- and submitted it as a sixteen page proposal. In one month, I find out if my work gets selected and I get a modest research grant. Based on the money they have available, I estimate they'll fund 15 people. It's a bit intimidating -- I'm just one guy, working in isolation on his own stuff, funding my work by taking odd jobs here and there, and I'm going up against the 50 best physicists in the world. As a model for reality, my stuff is ultimately pitted against string theory, a mathematical construction supported by the work of thousands of theorists, many much smarter than me.

My poor ego doesn't know what to think. On the one hand, I've always thought my own stuff was better than anyone else's -- that's why I work on it. But I never thought I'd have to prove it! Realistically, can I really have hatched one of the 15 best new ideas in foundational physics on the planet? It seems so unlikely, even if I do match the profile of eccentric scientist working in isolation from a volcano in the middle of the Pacific. What's even worse, I can't easily dismiss the judgment of the grant review committee if I don't get the grant -- the foundation board consists of solid guys, and I think the review panel will be going over my stuff in detail. The foundation's goals and mine are philosophically aligned, so failure will probably really mean my work just isn't that good. If I don't make the final cut, if my stuff isn't considered sufficiently promising, I'll have to seriously reconsider spending all my time on it. I wish there was a middle possibility, where maybe they could say my stuff was pretty good and worth at least something -- but it's all or nothing! Now I just have to wait and see what happens in a month.

Even if I don't get the grant, I'll probably keep working on physics -- just with less enthusiasm. Or I might work on other projects a bit more, like prepping for this year's Burning Man. Even if the physics work comes to naught, my life isn't so bad. Heck, just before C and I left Maui two weeks ago, R's friend Mike took the three of us out on the Baywatch Hawaii cigarette boat, which he'd just purchased:

Maui boat

We cruised around the upper west side bays and beaches, spent the night on a sub tender with a shark cage on the stern, and in the morning drove the cigarette boat to Lanai in twenty minutes, for lunch. In the immortal words of Ferris Bueller: "I love driving it. It is so choice. If you have the means I highly recommend picking one up." C was beautiful as ever, and it was great of R to bring us along. I owe him a lot -- he's putting me up at The Ranch in California right now, and has been a good friend ( if a bit of a task master ;). C and I are going to be hopping around the state for the summer, seeing people we've missed by being on Maui for two years. If I get the grant, I'll travel around and talk with other physicists. If I don't... well, I'll be bummed, but I'll be OK, and my ego will be less insufferable.

Interesting.

I just handed a paper to Anthony Aguirre today, for a final project in GR (my paper was called "A Brief History of the Holographic Principle". As I handed it to him I said "I made some very speculative remarks towards the end" and he said "great!" :) If it were any other prof, I would have been more careful, but he seems to like people who try to think out of the box. I'll post a link to my paper, even though some of it is probably silly... haven't decided whether I want to put it on [Unknown LJ tag] or just my own journal yet.

Good luck on the submission. And I'd be curious to hear what you don't like about string theory some time, although I guess it's probably a "long story". I'd say it's a victim of it's own success mostly; it fits the world so well that nobody has even figured out a way yet in which it might be wrong :)

for a final project in GR
meant to say paper/essay not project. I felt a bit guilty that it's about physics and I barely put any equations in it at all.

Hey Jeff. If you'd like to see it, I could email you a copy of the proposal I submitted. I'd be interested to hear your comments, especially regarding the last section on quantum mechanics.

On string theory, it's not such a long story. The theory just doesn't seem to say anything about the standard model or gravity that isn't in the standard model or gravity already. It does say things that aren't in the standard model, though most can't be tested. One string theory prediction that can be tested is the existence of super-symmetry partners. Do you agree string theory is in trouble if they aren't found?

Took a look at it. Looks like a pretty solid candidate for funding to me, but I guess it depends on what it's going up against (I'd have to see the others). Getting the physical fermions from Fadeev-Popov ghosts of a bosonic connection is interesting. Seems like it would get pretty messy, like, you'd have to ignore some ghosts (such as the anti-commuting scalars) but promote others to a physical level of existence. Although I haven't looked at what you're doing very closely to see if this becomes an issue.

As for the quantum mechanics bit... also interesting although I'm not sure how new it is. Sounds like a combination of several things people have probably thought about already, and not gotten very far on. But who knows, maybe putting them all together will lead somewhere. I'm not fond of "complex probability" distributions (although I know some people have tried them) because I'm not sure what meaning that has or why it deserves to be called probability. So I think there's a bit left to be done in trying to interpret that (although you mention this). I like the Bayesian approach, and the connection with the relational interpretation. I'm not sure what "universal action reservoir" means physically... did you have something in mind? Or are you just naming it that in analogy with statmech?

I notice you cite Tegmark a couple times, and your intro in particular seems like a heavy nod in his direction. Flattery never hurts, I guess :) On the whole, I think you have a lot of clever ideas in there which, in an ideal world, should definitely be funded. The question is whether the judges will see them as a higher priority than the other entries. Well, again I wish you luck. I'm going on vacation for almost a week starting tomorrow, so if I don't respond for a while, that's why.

Thanks Jeff, your comments were right on, which is encouraging.

I agree the complex "probability" distribution is strange, and I'm not sure what to make of it. But it does seem to work. The interesting thing is that when you use the complex probability distribution to calculate the probability for what you might actually measure, you get a real valued result. It's the same as standard QM that way. And yes, I did call it a "universal action reservoir" in analogy with stat mech. I wasn't sure what better to call it. Any ideas? I'll be more surprised than anyone if no one else has approached QM this way before, but I haven't found mention of it anywhere yet. I still assign low probability to it being a new idea -- it could have been conceived by anyone in the last fifty years.

Hmm, that seems to be the only actual question you had. And your observations don't need correcting -- you get points for comprehension. ;) I did go a little out of my way to flatter the institute director, but it seemed impossible not to mention the anthropic principle when proposing a TOE in today's climate, and he had put out the most sensible (if a bit whacky) technical paper on it.

The "ghosts as physical fermions" idea is probably the most significant and serious idea in the proposal. It seems to work well. If I get the grant, I'll look forward to that idea getting some attention. Maybe enough attention for people to dislike it, but I sure hope to find out. :)

Welcome back to the mainland. Although it's Baywatch, I feel like that movie file needs cheese Miami Vice-style music.

I hope that your theory/proposal is as good as your ego hopes it is. In the meanwhile, direct your fidgeting toward BMan plotting.

Yah, we had an ipod and speakers blaring appropriate music, but it couldn't compete with the engines.

Good luck with the proposal.
You forget a third option for your research: work harder. I think part of what ones misses out on not being part of academia is the competitive aspects and the insight and inspiration from discussion with others in the same field. I don't do well with competition myself, but I do get inspired by watching others and hearing about new research.

True -- I am often inspired by the few interactions I have with other physicists.

I get sea sick just watching that video.

given the trials of dating and the trials of physics proposal writing, I think dating is easier.

Hello! I just happened across your livejournal, via [info]roxymartini's, and am intrigued. I am a graduate student in physics also prone to various adventures. I suppose my journal will speak for itself. Anyway, greetings and introductions. We seem to have a few lj-friends in common already. Do you know [info]pbrane?

Good luck on the proposal. It sounds like quite an opportunity!

Hi nibot (Tobin?). I haven't linked to many physics people over LJ because this has always been more of a personal journal for me. But... I guess it wouldn't hurt that bad to mix them. I've seen pbrane's posts a few times, but I'll go ahead and LJ friend him.

It is good to see another physicist errant out in the world. And you're a grad student... What are you interested in the most?
