Move Over, Quantum Cryptography: Classical Physics Can Be Unbreakable Too

bh_doc Re:unbreakable been around for a while (126 comments)

Funnily enough, "quantum key distribution" is what it's actually generally referred to in the field.

First Von Neumann Architecture Quantum Computer

bh_doc Re:Von Neumann arch = Executable code in ram (90 comments)

You misunderstand qubits. A qubit can hold 0, 1, or a linear combination of 0 and 1, and with complex parameters (as in, real and imaginary). These are not discrete like digital information, they are continuous. While two bits can hold two dimensions of discrete information (amounting to 2^2 = 4 combinations), two qubits can hold four dimensions (2 times 2, because the parameters are complex) of continuous information (amounting to an infinity of combinations).

Discretization of qubits only happens when they are measured.

Do You Really Need a Discrete Sound Card?

bh_doc Re:Educate yourselves (520 comments)

What about homophones? To, two, too? They're, their, there? The meaning of these words* in written English is well defined because they are spelled differently, yet in spoken English their meaning can only be inferred from context as they sound the same. There are also words spelled the same but with different pronunciations (e.g. desert, bow).

*I realise they're is a contraction, not a word, but you get the idea.

What about abbreviations? How do you pronounce Mr., for example?

What about dollar values? If I gave you $2, would you give me "dollars two"?

Mr. Pike, Tear Down This ASCII Wall!

bh_doc Re:huh (728 comments)

As a scientist who has a fair bit of coding experience, including LabVIEW, ++ this.

What particularly annoys me about visual code like LabVIEW is that you can't diff. So change tracking is a pain in the arse, and forget distributed development.

LabVIEW itself is good for setting up a quick UI and connecting things to it, but any serious processing? ...No, thanks. If I could get my hands on something else that had the UI prototyping ease, connectivity to experimental devices (motion controllers, for example), but based on a textual language, I'd be a happy camper. (There are some things that come close, I'm sure, though I've not had the time to properly search. Busy scientist is busy...)

US Objects To the Kilogram

bh_doc Re:Get rid of the artifact? (538 comments)

Nice idea, but it's circular. Energy is defined in terms of mass (and distance and time). You need Plank's constant to convert from photon frequency to energy, and unless you already have a definition for the mass unit (kg), Plank's constant becomes essentially arbitrary.

Quantum Computing Explained! (Well, Sorta)

bh_doc Re:Um, what now? (145 comments)

No, he's just wrong, or at the very least severely dumbing down the real picture for the sake of placating the lay audience (which Slashdot is, generally speaking, not). There's a few examples of this already on the first page - I didn't even make it to the second...

That seems to be a problem with a lot of modern science: correct, brief, understandable to the layman. Pick two.

Neptune May Have Eaten a Planet and Stolen Its Moon

bh_doc Re:amphromoporthizing (145 comments)

The theory doesn't anthropomorphize the planet. The article describing the theory does, because that makes it more accessible and interesting to general readers.

Remember, not everyone is an emotionless nerd. Some of us like allegories.

So close... Rainbows End. It even points out the curious lack of an apostrophe in the book itself.

Unless you were talking about the album or the amusement park.

Yeah, I'm nitpicking. :-)

Apple Removes Wi-Fi Finders From App Store

bh_doc Re:Thank you Apple! (461 comments)

On something tangential: "mobile phones" versus "cell phones". Where I live, "mobile phone" is synonymous with the (less common) "cell phone" - this is a well known difference in language that's been around for a long while. Its interesting to see you use the two terms with different meanings, when I would still say both devices are "mobile" phones. Considering that what you call "mobile" phones will gradually supercede "cell" phones, do you suppose we are seeing the convergence of language, here?

AU Authority Moves To Censor Net Filtering Protest Site

bh_doc Re:Now does everyone realise (225 comments)

I agree about Scott Ludlum (and, to be fair, I also agree with a number of Greens policies), I just wish the Greens would back a more definite (and left-leaning) free speech idealism rather than the half-hearted "it doesn't work, but if it did, we'd consider it" policy they have at the moment.

Scientology Charged With Slavery, Human Trafficking

bh_doc Re:Yes... (802 comments)

The distinction between a religion and a cult, to my mind, isn't the quality of their beliefs-- we all believe utterly ridiculous things. (Do you actually believe in the *electron*? Or that we're all actually collections of waves? Quantum mechanics is as ridiculous as the virgin birth-- in fact, quantum mechanics ALLOWS for the virgin birth, since everything is possible (if highly improbable) in quantum mechanics).

The electron model and quantum mechanics both are predictive and thus testable, experimentally observed, and thoroughly verified to be accurate descriptions of reality. Suggesting that belief in them is "ridiculous" is, well, ridiculous. If something accurately describes reality, how can you distinguish it from reality?

Choosing a Personal Printer For the Long Haul

Considering the issues of planned obsolescence, how is it that suppliers that lease remain profitable? I must be missing something, because I don't see how they can afford make it more cost effective for their customers to lease from them than to outright buy stuff.

Creationist group launches new science journal

bh_doc bh_doc writes  |  about 7 years ago

bh_doc writes "The journal Nature is reporting that the organization responsible for a US$27-million creation museum in Kentucky is launching its own "peer-reviewed" science journal in response to perceived bias from existing journals. "On 9 January, Answers in Genesis, a Christian ministry run by evangelical Ken Ham, launched Answers Research Journal (ARJ), a free, online publication devoted to research on "recent Creation and the global Flood within a biblical framework". Papers will be peer reviewed by those who "support the positions taken by the journal"""
