Economics/Business ... Science ... Technology ...

The cover story in the December, 2014 issue of Scientific American was about “World Changing Ideas, 10 Transformative Technologies”. I usually take articles like this, which predict the next big techno revolution, with a grain of salt (or less than a grain, since I’m trying to keep a low-sodium diet). Science magazines are good at tracking the latest interesting ideas coming out of the research labs and theoretical papers, but they aren’t all that sharp regarding market economics. And they often do not appreciate the engineering challenges and the skills that are needed to bridge the gap between an interesting new technology and the means to design, produce and successfully market a new gizmo (or gizmo system).

So, you see all sorts of interesting possibilities in magazines like Popular Science and SciAm (although really, SciAm should go back to its former focus on “pure science” and leave the inaccurate predictions about the impact of emerging discoveries in the real world to mags like Popular Science). But very seldom do you look actually look back 3 or 4 years later and say “hey, they were right about those thingies, which they said would soon be in use”.

One of the big-ten technologies that SciAm thinks will be a game changer is “wireless charging with sound waves”. The subtitle to the article sums it up: “An efficient way to beam electricity through the air”. In a nutshell, a young woman named Meredith Perry got interested  »  continue reading …

Brain / Mind ... Religion ... Zen ...

This is going to be one of those schizophrenic essays, where it is time to speak of many things: ships, shoes and sealing wax, walruses, etc. But actually, I want to start out with something about brain activity during meditation, and then talk about why I finally understand atheists (a little better, anyway). Just in time for the holidays! (Well, a little late for Hanukkah, admittedly . . . )

So, first off – meditation. There was an interesting article in the November 2014 issue of Scientific American about “The Mind of the Meditator”. The article was something of a puff-job about the many psycho-physical benefits of meditation. It cites all sorts of positive effects in the brain and with behavior; but despite the alleged focus of SciAm on hard science, the authors forgot to ponder which way the lines of causation were running here.

I.e., were these benefits the RESULT of the meditation practice, or did they help allow the meditator to meditate? The unsaid presumption behind the article seems to be that anyone can practice meditation and everyone should. But life is usually more complicated than  »  continue reading …

Art & Entertainment ... Current Affairs ... Foreign Relations/World Affairs ...

Here’s a quick “current affairs” P.S. to my reflections on Interstellar (posted 10 minutes ago). Speaking of movies, North Korea has turned a “middling” political comedy film into a potential blockbuster for Sony, its producer. Yes, I’m taking about “The Interview“. As you know, the film plot involves a fictional US CIA attempt to assassinate North Korean dictator Kim Jong-un by recruiting two unwitting journalists who arranged an interview with him. The film was supposed to be released on Christmas Day in theaters nationwide, but got pulled after government or military agents from North Korea hacked Sony’s computer system in retaliation for the movie’s “insult to the dignity of the great leader”.

I have no sympathy for Kim or his stooges. However, what does bother me about all this is that Sony and the theater industry picked Christmas as the release date. According one of the mini-reviews, this film “follows the hysterically violent misadventures of idiotic talk-show host Dave Skylark and his underachieving producer, Aaron”. Another review notes that the film contains “crude and sexual humor, nudity, some drug use and bloody violence”. Is that where our nation is right now? A violent film about a political assassination is considered to be a “Christmas film”? I mean, couldn’t they have waited until New Years in order to respect a major religion’s celebration of the birth of its “prince of peace”? Would Sony be so insensitive as to release a comedy about political violence in Saudi Arabia or Egypt at the start of Ramadan?

So, thanks Kim Jong-un and his hacking squad. I darn well know that they weren’t defending the sanctity of the Christ-child’s birth by taking down part of the Sony network, but you never know when an evil force might remind us that we are not entirely free from evil either.

Art & Entertainment ... Outer Space ... Science ...

I’ve read a lot lately about the movie “Interstellar”. I haven’t seen it, and I probably won’t see it anytime soon. But it sounds pretty interesting given that it uses some very heavy ideas from modern physics and cosmology to cobble a science-fiction / outer-space / dark-future story together. I’ve read that the producers enlisted a world-class physicist, Kip Thorne, to help them “keep it real”. But in the end, Hollywood is Hollywood and entertainment comes before accuracy. From what I’ve read, the whole thing turns into a hot scientific mess, with the hero-astronaut falling down into a black hole past the event-horizon “point of no return”, and yet somehow getting out intact.

This is where the filmmakers obviously told Kip to stay away. (Although, Dr. Thorne is known for some pretty wacky ideas, including the very unlikely idea of using a portable wormhole as an escape hatch from the gravity time dilation effect, thus allowing a person subject to relativistic time slow-down to live in both his or her past, and in his or her present!) Under the laws of physics as we know them, you can’t venture past an event horizon and get out. There are various theories as to how the information about you or anything else that would fall through an event horizon can get out (although you wouldn’t know how to reconstruct and interpret it), and how eventually over many billions of years, perhaps everything in a black hole gets out via some sort of quantum evaporation process. But you can’t send a probe down get any sort of an immediate and usable signal back from it, not even a “gravity wave” signal (which currently cannot be detected anyway for being so faint).

And then there’s the spaghetti-ification factor, the fact that as you approach the core of the black hole, tidal gravitational forces would stretch you into a thin string of matter. Oh, and as if that’s not enough, now there’s the firewall paradox, the possibility that  »  continue reading …

Personal Reflections ... Psychology ...

Here’s a quick blog thought for when you’re feeling blue — perhaps the December blues, when “the holiday season” is getting on your nerves and the cold and early darkness is starting to bring you down.

Or let’s say that your life seems disappointing, because the great dreams and promises of your youth just didn’t come to pass . . . There’s an article in this months Atlantic about the “U” shaped curve of life satisfaction. According to various studies and interpretations of those studies, we are generally pretty happy with our lives as children and in our early adulthood, then things go downhill until bottoming out in our mid to late 40s. We hit bottom, but things start seeming better to us in our 50s and better still in our 60s and 70s.

So maybe you’re now 46 years old and don’t feel very optimistic, maybe you are fighting off a mid-life crisis. Or maybe you’re like me, having gotten thru my 40s,  »  continue reading …

Current Affairs ...

I decided to wait a bit until offering any comments on the Grand Jury decision not to criminally indict Ferguson, MO Police Officer Darren Wilson for shooting and killing Michael Brown this past August 9. I’m not qualified to offer any grand observations about the current state of race relations in America, nor am I about to go into why the criminal justice system seems to unfairly treat so many African American people.

I am, however, impliedly saying this much: I do not think the “police problem” is reducible to one or two simple factors, such as the notion that the overall law enforcement system is controlled by “white America” (not sure if that means non-Latin Euro-Americans only, or also includes Asian Americans and Latinos having largely Euro and non-native blood) and is designed to keep “people of color” under their control. I’m not saying that this notion is entirely untrue; but it’s far from the whole story either, I suspect. However, at the moment, the whole story is beyond my ability to grasp and intelligently comment on.

I will offer comments on two more immediate issues, based on what I’ve read and seen on the news sites about the evidence that the Grand Jury considered (along with the background info on Michael Brown and Darren Wilson that the press has dug up over time). The first thing that strikes me is that both of these men had clean records. As far as I can tell from what the press has reported, you wouldn’t have suspected that either one of them  »  continue reading …

Art & Entertainment ... Society ... Technology ...

In updating my web site pages about the modern academic interest regarding the physics and metaphysics of human consciousness, I made reference more than once to a popular movie that had some interesting things to say about consciousness. i.e., the 1999 sci-fi classic “The Matrix”. I don’t believe that there are very many Americans out there who haven’t at least heard about, if not seen The Matrix . . . and many have seen it more than once, including the two sequels (Matrix Reloaded and Matrix Revolutions, which like all sequels, just weren’t as brilliant as the original).

Well, obviously I am rather familiar with The Matrix . . . but let me admit it, I never sat down to watch it. Thus, I finally decided to get with it, 15 years later. I don’t pay for cable and I don’t have a good streaming connection, but you can pick up a used Matrix DVD for $3 or less these days on eBay, so I am finally “Matricized”.

How did I like it? Well, the acting was good and the characters were compelling. The cinema work was quite good, and the techno-creepy aspects to it were about on par with some of the wackier X-Files episodes. But as to the plot . . . well, the overall “big idea” that we are all living in world that’s not really real, that what lies beneath our conscious experiences is different  »  continue reading …
