Quantum Algorithms and the Strange Nature of Quantum Theory

Over at Information Processing, the InfoProcessor talks about teaching Bell’s theorem:

I find that the hardest thing about teaching this material in class is that, after half a year of training students’ brains to think quantum mechanically, it is extremely difficult to get them to feel the weirdness of Bell’s theorem and spooky action. It all seems quite normal to them in the context of the course — they know how to calculate, and that’s just how quantum mechanics works!

The Same Title?

On the arxiv Friday:

arXiv:0802.4248
Title: Coexistence of qubit effects
Authors: Peter Stano, Daniel Reitzner, Teiko Heinosaari
Comments: A paper with identical title is being published on the arXiv simultaneously by Paul Busch and Heinz-Jurgen Schmidt. These authors solve the same problem independently with a different method.

arXiv:0802.4167
Title: Coexistence of qubit effects
Authors: Paul Busch, Heinz-Jürgen Schmidt
Comments: A paper with identical title is being published on the arXiv simultaneously by Teiko Heinosaari, Daniel Reitzner and Peter Stano. These authors solve the same problem independently with a different method

Chosing the same title seems a bit strange to me. I mean simultaneous result posting happens quite frequently, but with the same title? But at least this answers a question I’ve always had which is whether the arxiv allows papers with the same title.

Slandering Ants Anthropically

Another checkmark in front of the “antrhopic reasoning is whack”:

arXiv:0802.4121
Title: Ants are not Conscious
Authors: Russell K. Standish
Anthropic reasoning is a form of statistical reasoning based upon finding oneself a member of a particular reference class of conscious beings. By considering empirical distribution functions defined over animal life on Earth, we can deduce that the vast bulk of animal life is unlikely to be conscious. As a side effect of these deliberations, I also show that naturally occurring fragmentation/coalescence processes give rise to a power law distribution of fragment sizes, a previously unknown mechanism for generating power laws.

Scirate.com Trackbacks

Some of you know (and use) the website I created a year ago, Scirate.com, a place where arXiv papers can be voted for digg style and comments can be left on the papers. After a while of not tinkering much with the website I’m beginning to add more features that I’ve been thinking about for a while now. The first feature is just a small one: the ability for the website to send trackbacks to the arXiv when someone comments on a paper. After some false starts I think I’ve got this feature up and running, and indeed the first trackback now appears for arXiv:0802.3351.
Now, of course, the bigger question is how to get more participation for the website from the more scientists (not everyone is as ungrumpy as the quantum computing community, it seems.)

Assorted Technology Bits

Technology tidbits of assorted flavors:

  • I think I just made myself dizzy.
  • Multi-touch to the max, dude!
  • What does it take to build the next Silicon Valley (besides Gallium Arsenide?) Via John Cook’s Venture Blog comes this report.
  • Bill Gates uses LinkedIn and asks: “How can we do more to encourage young people to pursue careers in science and technology?” (Is it wrong that my knee jerk reaction is “eliminate middle school?” 🙂 Oh and look I have more LinkedIn connections than Bill Gates! He has more dollars, though, I guess. I bet I have more joke-like “Bacon” paraphernalia though!

HD Shroud of Turin

Coming soon to a desktop near you: Your own digital Jesus. (Someone to hear your prayers. Someone who’s there. As much as a collection of bits representing the image of a sheet can be there, I guess that is.)
Yeah I just wrote this post because upon reading the article I couldn’t get that damn Depeche Mode song out of my head (or the Johnny Cash version.) Begone you fowl occupier of my neurons which could actually be doing some work!

If Only I'd Founded "iPho"

Quick, Batman! To the trademark-mobile along with a stack of three or four letter company names:

Feb 27 (Reuters) – On-demand business phone service provider Nuvio Corp said it filed a lawsuit against Garmin International Inc…alleging Garmin’s Nuvifone infringes on Nuvio trademark, which it uses on its phones and telephony services.

Popular Science for Scientists?

Over at Cocktail Party Physics, Jennifer Ouellette shares her thoughts on good science communication

I’ve learned over the course of my varied career that the trick to all good science communication is being able to boil a complicated science story down to its most basic components — the “core narrative” — to which one can then add layers of detail and complexity to tailor the narrative to a wide range of target audiences.
The main point I tried to get across in that first workshop is that this is not the same thing as the “dumbing down” epithet that many physicists like to fling at popular approaches to difficult subjects.

Beside the fact that physicists (and scientists of all stripes don’t-think-you’re-getting-off-easy-you-chemists) like to call things “dumbing down” simply because it makes them seem smarter than they might be, I think Jennifer is exactly right: the best popular science I remember reading never felt like they were dumbing things down for me. (In this way does the best popular science share a similarity with the best children’s literature?) I don’t remember reading “Godel, Escher, and Bach” and thinking it was oversimplifying the Church-Turing thesis. I don’t remember reading “A Brief History of Time” and thinking Hawking was pulling his punches (although I do remember I disagreed with him on all sorts of topics.) “The Turing Omnibus” from my recollections was certainly not about dumbing things down: it’s where I first learned about computational complexity classes, analog computers, and the busy beaver problem. The explanations I remember were not contrived and oversimplified, from my perspective, but seemed like actual objects the scientists were working with, explained without technical jargon and complicated analysis, but with their scientific heart still beating.
But this got me wondering. Once upon a time, I was a great consumer of popular science. I’m fairly certain I read every popular science book in my hometown library (along with the books all the books on pseudoscience as well.) But over the years I’ve read less and less popular science. Why has that been?
