The wisdom of knowing what to ask

By PAUL ERICSON, Editor, Rochester Business Journal, January 29, 2016

Here’s a question for you:

“What is information and where does it ultimately originate?”

And another:

“Is the universe a great mechanism, a great computation, a great symmetry, a great accident or a great thought?”


The first question was posed by the physicist and writer Paul Davies, the second by John Barrow, a cosmologist, theoretical physicist and mathematician. Both were posted online nearly two decades ago at Edge.org, then a fledgling website created by John Brockman, an author and literary agent for science writers.

Writing back then about Edge and its World Question Center, I concluded: “If a few of those questions don’t get the wheels in the brain spinning, sending some thoughts flying out of the box, nothing will.”

Not long ago I returned to Edge after a few years’ absence and was happy to find it alive and well. The site’s mission remains unchanged: “To arrive at the edge of the world’s knowledge, seek out the most complex and sophisticated minds, put them in a room together, and have them ask each other the questions they are asking themselves.”

One of the site’s top recurring features is the Annual Question. Over the years, scientists and thinkers in a range of disciplines have responded to queries such as these: “What is the most important invention of the last 2,000 years?” (1999); “What questions have disappeared?” (2001); “What do you believe is true even though you cannot prove it?” (2005); “What should we be worried about?” (2013); and “What do you think about machines that think?” (2015).

The question for 2016—“What do you consider the most interesting recent (scientific) news? What makes it important?”—already has drawn nearly 200 responses from contributors ranging from 2004 Nobel Prize-winning physicist Frank Wilczek to musician Peter Gabriel.

Among the others posting thoughts on this year’s question is Lisa Randall, a theoretical physicist at Harvard University and author of several books. As it happens, I just started reading her latest book, “Dark Matter and the Dinosaurs: The Astounding Interconnectedness of the Universe.” Among the last year’s news she cites are the discovery of a new species of human and more accurate data of species loss that could mean the Earth is on a path toward a sixth extinction. But Randall adds that some of the most important new knowledge likely is not yet apparent. Revolutionary discoveries are the result of many years’ work and “the headlines of any given year are not necessarily representative of what is most significant.”

OK, you might be wondering how these esoteric musings are relevant to you or me. And in fact, if you want solutions to key problems, Edge probably isn’t the place to look. Its pursuit is not answers but questions—in particular, which are the most important ones to be asking.

Randall in her book notes that much of what we know about the 13.8 billion-year-old universe has been discovered only in the last century. Take dark matter, so named because it doesn’t interact with light; it accounts for roughly 85 percent of the matter in the universe—a fact not known until the last several decades.

I’d wager that this breakthrough and others like it originated with scientists asking questions that at the time sounded offbeat or even ridiculous. But discoveries happen only when someone, asking why not, scales the walls of conventional wisdom.

Unlike science, politics these days is awash in certitude. Candidates who admit to any uncertainty or who don’t know all the answers stand little chance of getting elected. Hubris also ruled in the run-up to the financial crisis; we all know how badly that ended.

It’s not wrong to want elected officials who can get things done; those who are paralyzed by indecision ought to find another line of work. But curiosity, imagination and a strong desire to truly understand the nature of things—along with a good measure of humility—are traits that should be rewarded, not belittled.

What will it take for that to happen? Good question.

         The question that serves your inner spirit best is the first one presented, the one by Paul Davis two decades ago.

“What is information and where does it ultimately originate?”

         This is a question you have seen before, more than once, over the years. You used to use some of Davis’ essays in your classes from time to time to have students read, think and write in that order. – Amorella

         1510 hours. The first question I have presently is defining ‘information’. For instance, in context with the greater question I have to say is that the nature of humankind is the only real we ask the question, so, in a sense, the ‘information’ originates with our species. Otherwise, --

information – noun

1 facts provided or learned about something or someone: a vital piece of information.

Law a formal criminal charge lodged with a court or magistrate by a prosecutor without the aid of a grand jury: the tenant may lay an information against his landlord.

2 what is conveyed or represented by a particular arrangement or sequence of things: genetically transmitted information.

Computing data as processed, stored, or transmitted by a computer.
• (in information theory) a mathematical quantity expressing the probability of occurrence of a particular sequence of symbols, impulses, etc., as contrasted with that of alternative sequences.

ORIGIN

Late Middle English (also in the sense ‘formation of the mind, teaching’), via Old French from Latin informatio(n-), from the verb informer.

Information (shortened as info) is that which informs. In other words, it is the answer to a question of some kind. It is also that from which data and knowledge can be derived, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts. As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.

At its most fundamental, information is any propagation of cause and effect within a system. Information is conveyed either as the content of a message or through direct or indirect observation of some thing. That which is perceived can be construed as a message in its own right, and in that sense, information is always conveyed as the content of a message.

Information can be encoded into various forms for transmission and interpretation (for example, information may be encoded into a sequence of signs, or transmitted via a sequence of signals). It can also be encrypted for safe storage and communication.
Information resolves uncertainty. The uncertainty of an event is measured by its probability of occurrence and is inversely proportional to that. The more uncertain an event, the more information is required to resolve uncertainty of that event. The bit is a typical unit of information, but other units such as the nat may be used. Example: information in one "fair" coin flip: log2(2/1) = 1 bit, and in two fair coin flips is log2(4/1) = 2 bits.

The concept that information is the message has different meanings in different contexts. Thus the concept of information becomes closely related to notions of constraint, communication, control, data, form, education, knowledge, meaning, understanding, mental stimuli, pattern, perception, representation, and entropy . . ..

One has to have a definition first, even if you are the Paul Davis. To avoid ridicule I often keep my mouth shut. I blame it on innate arrogance. [This was quite bothersome on tests from high school through the GRE in college.]

         Information encloses in your books. This complicates the world to you because the novels are mostly based on fiction. – Amorella

         1604 hours. As such I have come to the conclusion quite some time ago that the whole world if also based on fiction, how much so, I have no idea but my dark humor innately suggests the world is more fiction than we might like to think. I also feel that once dead and gone, so to speak, we are more likely to realize this. Once we no longer have to survive physically our eyes remain open to see anew.


         Everyone is entitled to an opinion even if it is read as a statement. Post. - Amorella
