Quantifying Information Content Does Not Bring Meaning Fr...

It is perfectly true that redundancy aids recognition of a signal as a language or a code, and this recognition is crucial to SETI. However, Shannon’s method provides only a quantitative measure of the complexity of a language or signaling system—not a translation. And while it is axiomatic in cryptology that redundancy helps in deciphering a text, the task of decipherment/cryptanalysis is to move from an encoded text to the original text—not from text to meaning. To get from text to me...

 Explorer VS Adventurer

As Ursula K. LeGuin writes in The Dispossessed, a novel in which a man returns to Earth for the first time from an anarchist colony: “The explorer who will not come back or send back his ships to tell his tale is not an explorer, only an adventurer.”

 Words are More Powerful than Pictures

This “algebraic” flexibility of a word encapsulates the essence of something while leaving unnecessary concretes out. A photo doesn’t and can’t. Further, a word offers enormous flexibility in terms of input/output. It can be spoken, thought, gestured (as in sign language), written, grammatically combined with other words, or stored with very little memory. A photo can’t. Words are altered by syntax and grammatical endings. A photo can’t be modified in this way, other than the temp...

 A Minority of Users Account for Majority of Online Comments

In July, NPR.org recorded nearly 33 million unique users, and 491,000 comments. But those comments came from just 19,400 commenters, Montgomery said. That's 0.06 percent of users who are commenting, a number that has stayed steady through 2016. When NPR analyzed the number of people who left at least one comment in both June and July, the numbers showed an even more interesting pattern: Just 4,300 users posted about 145 comments apiece, or 67 percent of all NPR.org comments for the two month...

 Metaphor in Science

Metaphor in science, Boyd suggests, is a version of the everyday process in which a metaphor is pressed into service to fill gaps in a language’s vocabulary, like rabbit ears to refer to the antennas that used to sprout from the tops of television sets. Scientists constantly discover new entities that lack an English name, so they often tap a metaphor to supply the needed label: selection in evolution, kettle pond in geology, linkage in genetics, and so on. But they aren’t shackled by the...

 Transclusion

Now, with respect to literature, authors are frequently faced with the task of re-explaining and restating background material that has been explained well elsewhere. If you could just borrow that material, those existing good explanations, and incorporate them (with automatic credit where due), your efforts could be spent stating what is new. We introduce the concept of transclusion to separate the arrangement of a document from its content. There is an underlying shared pool of contents, an...

 Scent as Data in a Beehive

To shield her antennae from the many bruising signals in the air, she walked with her head low. Air currents and electrical pulses from thousands of bees rippled against her, but Flora ignored them all. The pulsing track alone held her focus, clear and simple across the perilously busy lobby, where she had to slow down because of the tempest of data underfoot. A rush of workers came through in a tumult of scent and Flora lifted her head—then the rhythm of the foot-current drew her on. She ...

 Human Communication with Matrioshka Brains

Communication between humans and MB is essentially pointless.  The computational capacity difference between a MB and a human is on the order of 1016 (ten million billion) times greater than the difference between a human and a nematode (~109)!  A single MB can emulate the entire history of human thought in a few microseconds.  It is important to consider that intelligence may not be a linear process.  There is a rather large difference between the...

 How to Argue with a Creationist

Nye did not win, because he was fighting the wrong war. Nye argued like a scientist. He presented the evidence, gave logical explanations, and generally relied on demonstrable facts. He did a flawless job, but changed absolutely no-one's mind, because anyone who cares about science, reason and evidence already accepts evolution. Ham didn't even really argue. He just riled people up for a crusade - it was the evil liberal commie atheists trying to teach satan's lies, and him and his book of ...

 The Rate of Change of a Rate of Change

In scientific thought we adopt the simplest theory which will explain all the facts under consideration and enable us to predict new facts of the same kind. The catch in this criterion lies in the word 'simplest'. It is really an aesthetic canon such as we find implicit in our criticisms of poetry or painting. The layman finds such a law as dx/dt = K(d^2x/dy^2) much less simple than 'it oozes', of which it is the mathematical statement. The physicist reverses this judgment, and his statement ...
