Taxing Fools

This time of year always reminds me of the non-Abelian Aharonov-Bohm effect.
Whah? Well it’s due entirely to this colloquium on the non-abelian Aharonov-Bohm effect given by John Preskill:

This talk was originally schedule for April 1st. I was delighted. I’ve always wanted to give a talk on April 1st, and this subject seemed like the ideal one for that date. Then, in a stunning reversal, the talk was rescheduled for April 15th. I was shocked. Suddently, instead of speaking on the funniest day of the year, I was speaking on the least funny day of the year. I know that everyone is in a somber mood on April 15th, so I have decided that there will be no jokes in this talk. I’m sorry. I hope that you don’t find the talk to be overly taxing.

Classic! The closest I’ve ever come to giving a talk on a holiday was when I gave a talk here at UW on Valentines day. I’m still disappointed that I didn’t have enough jokes about the day. I’m sure my audience would have loved it.

Are You a Sink? Are You a Source?

In a fit of self-centeredness (okay, maybe I’m always in such a fit 🙂 ) I decided to see if I’m a source or a sink on the arXiv (or at least the arXiv as seen by Citebase.) Below are a list of my papers (excluding my thesis) which I’ve posted on the archive along with citation numbers and reference numbers. Using this I can see whether I am a source or a sink on the graph of citations.

So what’s the verdict? Well, one, it is depressing to make this list on Monday. And two, I’m a source by 52 citations. That means I’ve generated like six citations per year over my career. If I include my thesis in the above table, I definitely become a sink. Apparently writing your thesis really is a waste of time 😉
Anti-troll: And of course, all of this doesn’t matter. But it’s fun and self indulgant.

The Great Wedding Diet of 2007

(Note, the below plot is indicative of a method for losing weight which not exactly healthy and is not recommended!) Results of the great wedding diet of 2007:
Great Wedding Diet of 07
The method? Little food and running four to five miles every morning. Funny how that works.
Okay, for old times sake, here is, for comparison, my last diet:

Talk Next Week

For local Seattlites the following shameless self promotion message 🙂 Next Tuesday at 4pm I’m giving a talk in the Physics department (C421 Physics/Astronomy Building) for the Condensed Matter and Atomic (CMA) Physics Seminar. The title of the talk is “When Physics and Computer Science Collide: A Cross Cultural Extravaganza” and the abstract is

In 1994 Peter Shor discovered that computers operating according to quantum principles could efficiently factor integers and hence break many modern cryptosystems. Since this time researchers from disciplines–physics, computer science, chemistry, and mathematics–have been engaged in building an entirely new discipline now known as quantum information science. Being a highly interdisciplinary endeavor, quantum information science requires not just mastery of physics or of computer science, but an ability to take insights from both fields across the cultural divide. In this talk I will discuss how physicists can contribute to the computer science side of quantum computing and how computer scientists can contribute to the physics side of quantum computing via a series of vignettes taken from research in my group here at UW.

Upgraded

Just upgraded to Vista. Woot, no problems so far. Yeah, living in Seattle you just fall deeper and deeper into the “evil empire.” But it’s still fun to wave to Bill Gates when you go over the 520 bridge. And the real question is, how will Bill commute to the new Bill and Melinda Gates building which is closer to where I live? Maybe he will buy us a new bridge?

Deals Missed

Glancing over OVM Venture Partners website I noticed they had a list of companies they backed, but also a list of deals missed. Why am I posting this? Because last night our puppy destroyed a new rug we had purchased and I need something to pick myself up. Nothing like seeing a company that passed on Starbucks and still has a sense of humor about to lift you up.

Scirate.com


Dave, where have you been? Your posting has been almost nonexistent over the last few weeks. Why?
I’ve been busy.
Really? Academics are busy? I thought that they only taught one course per term. Sounds like you are a bunch of tax payer sponsored lazy bums to me.
Bah, you have no idea! Grumble, grumble. But more seriously I haven’t been blogging because I only have a certain small amount of free time and I’ve been dedicating all this time to a new project.
New project? Like your project to make an information theoretic transactional interpretation of quantum theory?
No, even more bizarre. A website.
A website? Come on, Dave, last time I created a website it took me like a few minutes. Are you really that slow?
I am slow. But that’s another issue. What took me so long was that I needed to learn php and a little javascript and extend my mastery of pyton to get the website working.
Ah, becoming a true computer scientist are you, Dave?
Hey, since Scott Aaronson can now claim to be “the second funniest physics blogger,” maybe with these skills I can claim to be “the second least funny computer science blogger!”
So what is this website of which you speak? I hope its not pornography related.
No, no pornography. The website is called scirate.com.
Scirate.com? Are you irate about science or something? I’m certainly irate about science…I hate how that damn thing called reality keeps dragging me down.
No, I love science. It doesn’t make me irate at all. Just filled with a deep calm. So take that! But anyway, scirate.com is a website inspired by digg.com, the arxiv, the open archives initiative, conversations I’ve had with Joe Renes, Michael Bremner, and a host of others, and my desire to have some fun.
Fun? So it IS pornography related.
No. No pornography. The idea came from the observation that while the arxiv is a amazing tool, one of the problems was that the volume of papers was high and, to put it bluntly, the quality of these papers was not necessarily so great. So the question became, how do I do something to filter out the arxiv? Now, of course, everyone will want a slightly different filter. One person’s noise might be indeed another persons operatic masterpeice. But there should be a way to produce at least “some” kind of filter based on the quality of the work. And certainly computers aren’t smart enough to do this filtering (okay that’s a challenge to all you AI people out there!) And using citations is too slow. But there is a group of experts out there who can do pretty good filtering…
Who?
You! And by “you” I mean the people who read the arxiv listings.
Me? What can I do?
Well, each day postings from the arxiv (actually only from quant-ph right now, see below) are listed onto scirate.com. If you are registered, you can then look through the listing and vote (or “Scite” as I call it) for the preprints. Then, when you display, or anyone else displays the page, the listing will be sorted by vote. So, with enough user participation, the hope is that the signal will “float” to the top. A noise filter!
Are you calling me a Butterworth filter?
Nothing of the sort. I’m calling you a useful!
Okay, but aren’t you worried about vote stuffing?
Certainly vote stuffing is possible. But I’m an optimist when it comes to others behavior. That being said, I have a few tricks for avoiding vote stuffing.
Fine, but aren’t you worried that this just adds another layer to the popularity contest of science. Aren’t you just adding another leg in the “publish or perish” beast?
No, I’m not worried. First of all to have an impact it must be used by more than a few crazies like those people who read this website. And if it is used by more than a few crazies, well then I think the site is worth it. Second of all, anyone who takes seriously citation data of any sort is setting themselves up for “the wrong kind of science.” Just because the reality of how academia works is a pain doesn’t mean that you have to buy into carrying about how cited your paper is. You should be doing science for the reasons of expanding knowledge.
Okay, maybe I’m a little interested. Oh wait, I’m a high energy theorist, but you only have quant-ph. Why?
Well right now I only have quant-ph. This is because quant-ph is what I read and I wanted to start somewhere familiar. Second, I do plan on extending it to the other arxiv’s and allowing you choose which arxiv’s to browse, etc. Third, the arxiv is moving to a new format for papers sometime soon and this will certainly break my oai harvester, so I will wait until they make that change before I attack the other arxivs.
Fair enough, but the site seems a little barebones, doesn’t it?
Yep. Mostly I’ve just been focusing on getting the barebones site up and running. Further improves will come if there is enough interest. And of course it would be great if users could tell me about problems their having or features they’d like to see. To do this I’ve set up a blog scirate.com/blog.
Why are the abstracts displayed in small font?
Click on them and find out.
I voted, but the paper didn’t change order.
Yes, right now you have to reload to get the new order. This will, eventually, be fixed.
Can’t you do something more sophisticated like feature X on digg.com?
Eventually there will be more features. Believe me I have a long list of ideas, but I’m always open to ideas. Again The Scirate Blog is a good place to post your ideas.
What software did you use to write the site? Why didn’t you use Pligg, the digg clone?
Php, mysql, javascript, some serverside ajax stuff, python. Doing things on your own is funner. Did I ever tell you about how I learned Calculus? I bought a book on quantum mechanics and on about page 12 came to an integral sign (the famous integral sign that Planck turned into a sum sign!) and didn’t know what it was. I took it to a teacher who knew it was an integral sign. So I went off and learned Calculus.
You really are obsessed with quantum theory, aren’t you?
Yes.
Well, Dave, I’ll see you later. I’ll see you at QIP right?
Um, did I mention I’m teaching this term?
You inserted that last sentence to make this blog post one big circle didn’t you?

2007: Year of the Beaver!

Today is a big day in sports news. No I’m not talking about the BCS championship. No, no, something much more important happened over the weekend.
Caltech Basketball team ended its losing streak! After 207 consecutive NCAA Division III loses, Caltech beat Bard College of New York 81-52! Okay, with that monkey off their back now all they need to do is beat one of their division foes…that’s a streak of over 22 years and 245 loses. Beaver Fever!
