Philosophy ... Religion ...

I read an interesting article on the RealClearReligion web site entitled “The Decline of Philosophy“. Hmmm, so someone else thinks that philosophy today ain’t what it used to be. I am presently listening to a CD course from the Teaching Company on philosophical metaphysics, and I too have some reservations about what modern philosophy is concerning itself with. The course is taught by Dr. David K. Johnson, a young philosophy professor at Kings College in Pennsylvania. Professor Johnson goes out of his way to make ontology relevant to the masses, and specializes in integrating pop cultural into his lectures, especially movies (he also repeatedly mentions his love for the sweet potato fries at Johnny Rocket’s).

And yet, so much of Dr. Johnson’s discussion and argument just seem irrelevant to me (despite my penchant for “deeper meanings” to things). Johnson’s lectures mostly boil down to a word games and battles between philosophers as to how cleverly they can apply the rules of logic. I get the impression from Johnson that he and his fellow modern philosophers certainly are very clever, but they don’t convey much that gives a better understanding of our selves, our lives and the environment and universe around us. Johnson has a very excitable lecturing style, and his enthusiasm almost bubbles over whenever he leaves us in a tangle of contradictory propositions and unanswerable questions. Ummmm . . . whatever happened to the old Greek philosophical notion that philosophy is to help us understand deeper truths? If Johnson’s course is any indication, philosophers today seem to be saying “there is no truth”.

The RCR article was written by a Catholic priest named Robert Barron (who is President of Mundelein Seminary near Chicago). Fr. Barron hasn’t taken notice of David Johnson, but he does open up his article by zeroing in on Dr. Daniel Dennett, who is one of the more outspoken proponents of “the new Atheism“. Barron believes that Dennett  »  continue reading …

Current Affairs ... Economics/Business ...

As 2014 came to an end, a variety of “year in review” articles cited French economist Thomas Piketty’s “Capital in the 21st Century” as perhaps the most important book in the business and economics field in quite some time. Piketty’s book has stirred up a lot of discussion and controversy about the problem of inequality in industrialized society. It’s well known that income inequality is inherent to any capitalistic economy; arguably, income inequality is needed in a system that progresses through competitive economic incentives. The apologist for capitalism basically argues that even though some people don’t do as well as others, and many remain poor, everyone is still better off because of the dynamic growth caused by capitalism. Even the lowest on the income ladder eventually do better than the poor in less dynamic economic systems.

Piketty changed the focus somewhat as to include wealth; it follows that if income is unequal, then wealth, what people manage to accumulate or save up over their lifetimes, is probably also going to be unequal. What Piketty has done, however, is to show (purportedly) that modern trends in wealth accumulation are reaching something of a “runaway” point, whereby the income and opportunities gap becomes so wide that hard work, good ideas and other talents (and also good luck, quite frankly) no longer rule the day. The situation is now reaching the point, according to Piketty, where economic elites have formed amidst the populace, elites that are increasingly restricted by parentage and location, such that if you’re not born with the right parents in the right place, your opportunities for a decent income and reasonable wealth (i.e., the good life of the “middle class”) aren’t very good. And they are getting worse with every new year.

So, Piketty has added fuel to the fire regarding the increasingly popular notion that the rich really are getting much richer, the poor much poorer, and the middle class  »  continue reading …

Weather ...

In December, 2012, there was an article in Scientific American (called “Winters of Our Discontent” by Charles Greene) saying that global warming was causing the Arctic ice cap to melt, and that such melting would mess up the usual Arctic air oscillation patterns. As a result, the eastern half of the USA would allegedly experience very cold winters starting in 2012-13. So, SciAm was warning us to expect a cold winter in return for the sins of our carbon-based civilization. But it didn’t happen that year; the winter of 2012-13 was mostly normal here in the east, temperature-wise. However, we did get socked the next year (last winter); the polar vortex kept on dipping downward from Canada and everyone east of the Mississippi did a fair amount of shivering, especially in February and early March. (And yes, I acknowledge that the shivering is relative; we coastal people who are used to 25 degree winters were really suffering at 10; but you inland people had to get down below zero before you started noticing it).

So, does this prove that global warming is here, clear for everyone to see in the eastern USA to see? (Not to mention the far West, with its extended heat and drought). The experts are arguing both ways on that idea. Recall that since 2000, we’ve had a very active hurricane pattern in the Atlantic; according to Weather Underground, 2003, 2005, 2008, 2010, 2011 and 2012 were on the top 10 list of hurricane seasons since 1851. These years gave us famous storms like Katrina, Wilma and Sandy. Various articles appeared attributing this trend to global warming. However, some studies go the other way on this. Since 2012, the Atlantic basin seems to have quieted down; 2014 was one of the least active years for hurricanes on record. IMHO, it’s still too soon to conclude that bigger and more frequent hurricanes are going to become a way of life because of CO2.

But what about those cold waves here in the east? We are in one right now,  »  continue reading …

Economics/Business ... Politics ...

There’s an interesting little debate going on in the “energy sector” these days about something called Enhanced Oil Recovery. It’s one of those boring things that could some day make a big difference in how our world works, but for now it’s mostly under the radar, save for a handful of researchers, energy industry planners, and environmentalists (including green energy developers who could be affected by it). The people who favor EOR (as they call it) are mostly Republicans; but with just a bit of political imagination, the Democrats could make a lot of good use of this idea. If only they had the wits to do so.

In its most boring, generic format, Enhanced Oil Recovery is the use of pressurized carbon dioxide gas to push petroleum out of oil wells that otherwise are considered “depleted”. Most depleted wells still have plenty of oil down in them, but getting to that oil and pumping it out costs more than the stuff is worth. If you could obtain reasonably priced carbon dioxide, you could pump this otherwise abandoned oil out cheaply enough to sell it and make some profit (well, perhaps not in today’s $50 a barrel oil market, but the current oil glut and price crash may be a temporary market over-shoot that will resolve itself, with oil eventually settling around $75 per barrel, about half-way between the current lows and the previous plateau of around $100 per barrel).

That’s the plain-vanilla version; there is now a maximum-strength EOR proposal, however, that environmentalists and green energy advocates will probably say comes right from the devil himself. In a recent article on the conservative Weekly Standard web site,  »  continue reading …

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 …
