AI, or Artificial Intelligence

Mary Shelley’s Frankenstein story was not created out of thin air.  Indeed, her novel’s subtitle is The Modern Prometheus.  Prometheus, a Titan of Greek mythology, brought fire to humanity and enraged the gods who knew that humans would eventually challenge their supremacy.  Dr. Frankenstein creates a creature from human body parts, and the creature demands his right to be treated as a human.  In Blade Runner (1982), replicants (bioengineered humanoids) demand their rights to be treated as humans.  In Short Circuit (1986), a military robot convinces the film’s humans that he has human consciousness (or a soul) when he laughs at a joke.  We have always thought that consciousness was a peculiarly human trait not shared by our animal cousins (despite the fact that science has no clear and agreed upon definition of “consciousness”); we have wised up lately.  Lest I forget, the origin story of all these stories is Genesis’s Garden of Eden, where our ancestors are told not to eat of the Tree of Knowledge of Good and Evil, “For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil” (KJV, Genesis 3:5).

Opinions

I would love this to be the last time I write about “opinions,” but I am sure it will not be considering the American obsession with “I have a right to my opinion” and “my opinion is as good as anyone else’s opinion.”

The most famous quip ever about opinions belongs to NY Senator Daniel Patrick Moynihan (1927 - 2003).  It goes, “Everyone is entitled to his own opinion, but not his own facts.”  Opinions look like facts, like declarations of the truth (“This statement is true”); but unlike factual statements, opinions are never provably true or false.  Indeed, not all factual statements are true, some are statements that are false.  But opinions are statements that are never demonstrably true or false.  BELIEFS and POINTS OF VIEW, on the other hand, may consist of opinions and/or factual statements.

UFO’s


This article (here is his TED talk if you prefer videos to reading) prompted me to think about UFO’s.  And it’s a small leap from thinking to writing.

I have been fascinated by the idea of superior alien intelligences since as long as I can remember, most probably for the same psychological reasons as everyone else who has ever been obsessed by them.  I recall the name of Donald Keyhoe as an author whose books I consumed; his writings go way back to 1950.

From the Earth to the Moon

Exactly five decades ago, on July 20th, 1969 at 02:56 UTC, Commander Neil Armstrong, Jr. set foot on the Moon, the first human being ever to plant his feet solidly on another planet or planet-like object. This event was set in motion eight years before, on May 25th, 1961, when President John F Kennedy spoke these words: “I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth.” 

The Space Race (between the USSR and the USA) began the day that Americans heard the radio beeps of an unmanned space vehicle called Sputnik on October 4th, 1957. Less than a year later, July 29th, 1958, President Eisenhower established NASA to compete head to head with our Cold War adversary. Soviet Cosmonaut Yuri Gagarin made man’s first flight into space on April 12th, 1961, Kennedy spoke his stirring words a few weeks after Gagarin’s flight, and the second stage of the Space Race was on – the race to the Moon! NASA responded immediately with the Apollo program, dedicated to putting men on the Moon before the decade was out. Apollo’s brightest moment occurred on July 20th, 1969, fifty years ago today.

Mars or Bust


In an address to Congress on May 25th, 1961, President John F Kennedy spoke these words: “I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth.”  He meant it, we did it, and his words still resonate today.

On July 4th, 2019, President Donald J Trump asserted: “Someday soon, we will plant the American flag on Mars.  It’s happening.”  Whether anyone will remember his words fifty years from now, we cannot know.  But let’s assume he meant what he said, even if “someday soon” is not as definite a commitment as “in this decade.”  Let’s assume we intend to step foot on Mars someday.

HIPPO

I called the second essay in the Appendix of my book, To My Countrymen, "Gaian Issues" (Gaia is the ancient Greek goddess of the Earth). The essay laments the fact that Americans place Gaian (environmental) issues at the bottom of the heap of political issues that are important to them. And it lists the ten most significant Gaian issues (Global Warming / Climate Change is only one of them). Here is the list: 
  • Global Warming
  • Peak Oil
  • Rain Forests & Coral Reefs
  • Deforestation
  • Endangered Species – the Sixth Extinction – the Loss of Biodiversity
  • Over-fishing, over-hunting
  • GMO
  • Waste
  • Water
  • Human Population Growth

The Human Species

“We humans are a special species, we are at the top of the evolutionary pyramid, we are what God aimed at when he set evolution in motion.” 

“Well, that is a lovely thought, but it is not really true. Every individual creature that is alive today – humans, primates, mammals, dolphins – are as highly evolved as are you and me. They are all products of 450 million years of uninterrupted evolutionary success, just like you and me. No predator ever made a meal out of any of them before they had children. None of our ancestors, no matter how distant, ever died of an accident or a disease before they had children, more ancestors” 

“But we are surely superior to them all, to all non-human creatures, aren’t we?”

Plan B: Mars

The Space Between Us is a 2017 movie that I do NOT recommend as it is heartbreakingly depressing.

It’s the story of a boy who is born and raised on Mars whose heart (larger) and muscles (weaker) are adjusted to life on Mars but not on Earth.  He takes a trip to Earth to find his father and the girl he has fallen in love with via cyber chat.  But he can’t survive for long on the Earth, and in the end, he has to return to Mars.   “Home Sweet Home” say the boy and his father overlooking the barren red Martian landscape at movie’s end.  The sentiment is fake and it is obvious.

But the premise of the movie is stupid.  “If we had to, mankind could make a fresh start {on Mars}.  We’re in trouble and it’s our fault.  … Mars is a planet ripe and ready for life.”  We have made such a mess here on Earth that we need a backup plan, a Plan B, and Mars is it.  So, they begin to colonize Mars, 6-8 Earthlings at a time.

An Open Letter to American Creationists

To my Creationist friends – Young Earth Creationists (who believe that the Earth and the universe are only thousands of years old, not because the Bible told them so but because James Ussher, Church of Ireland Archbishop of Armagh and Primate of All Ireland declared in 1654 that creation took place at nightfall on 22 October 4004BC, some 6021 years ago), “plain old” Creationists (who believe that the physical universe must have been the creation of a supernatural deity) and Intelligent Designers (plain old Creationists who understand that they have to strip religion and God out of the equation in order to pass Constitutional muster).

How long have you wanted to have YOUR story respected?  Surely since only a few years after Charles Darwin published his On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life (1859) and The Descent of Man, and Selection in Relation to Sex (1871).  Surely since the awful Scopes Trial (1925), where the Christian prosecution prevailed, but not really.  We have been fighting Culture Wars (between fundamentalist Christians and seculars) for as long as we can remember.  And only one of the issues is the teaching of Darwinian Evolution in our public schools.  And wanting to challenge it on its own turf with the Biblical Creation story.  And being most recently slapped down by conservative Judge John E. Jones III, a George W Bush appointee, in Kitzmiller v. Dover Area School District (2005).

Getting Real about Global Warming

Before we begin, I need you to perform an experiment.  First, write down your estimate of the temperature of the water that you wash dishes (manually) with.  Next, write down your estimate of the temperature of the water that you bathe in (shower or bath).  In both cases, the hottest that you can tolerate without burning yourself.  After you write these numbers down, I want you to find your kitchen thermometer and measure how hot the water really was under both conditions.  When you have these four numbers, click below where it says “Read more »” and continue reading.

The Cosmos

These are all Galaxies in a piece of sky smaller than the Moon
This essay was written by a friend; I like it so much that I am posting it on my blog.  It’s not about politics or governance but it IS about perspective and we both agree on the importance of perspective, in politics and everywhere else.

The Cosmos

Cosmos is Greek for the world of the Heavens, the starry world.  That is: everything out there.  Everything that we can see or grasp or imagine.  All the big things (that, ironically, appear to us so infinitely tiny).
Most humans don't think cosmically.  Most humans' view of “the world” is their local "world," frequently not more than a 20-mile radius world.  Many affluent First-World citizens have a different perspective of "everything," perhaps the world itself, the planet Earth, or at least vacation spots in far-away places.  But for the most part, most First-Worlders do not ever think about the Earth proper; it is too vast to imagine except in very limited discussions.  For the most part, our “world” is our neighborhood, and we rarely think outside THAT box.

Two Trillion Galaxies

I have a friend who has a very nerdy geeky friend.  In short, he likes numbers.  It seems that whenever a new factoid with a number gets into the news, this fellow likes to play with it.  So, I decided to ask him to write up his reaction to the latest numbers news.  So, here it is, with some slight editing to make it easier to understand.
A few weeks ago, astronomers announced that our (observable) universe contains ten to twenty times as many galaxies as they thought it had (a galaxy is a collection of stars held together by the center of gravity of the galaxy.  Our own galaxy, called the “Milky Way,” contains some 200 billion star systems (a star system is the star at the core, all its planets, asteroids, comets and other junk that is held in place by the star’s gravity)).  And our galaxy is an average galaxy.  Galaxies are HUGE affairs (the Milky Way is some six hundred quadrillion (600,000,000,000,000,000 = 6 * 1017) miles in diameter), and each galaxy is mostly empty interstellar (between stars) space.  Just weeks ago, astronomers believed that the count of galaxies within the observable universe was some 200 billion (200,000,000,000 = 1011) galaxies, roughly the same number as the number of stars in the Milky Way.  Now they believe that the universe contains 2 trillion galaxies, ten times as many.

Greenhouse gas benchmark reached

I am not a climate scientist, not even a garden-variety generic scientist, so what I am about to say is all speculative horseshit.

NOAA (the National Oceanic and Atmospheric Administration) said today (May 6th, 2015): “Global carbon dioxide concentrations surpass 400 parts per million for the first month since measurements began.”

SETI – The Search for Extra-Terrestrial Intelligence

OK, this short blog post is a reality check.  “Are we really alone?”  Is Earth-based humanity the only intelligent species in the whole universe?  OK, we are pretty sure that we will find life – elemental life, single-celled life – pretty nearby and soon, on Mars, on one or more of Jupiter's or Saturn's moons.  But how about intelligent life, more intelligent than us – from whom we might learn SO much that would solve SO many human problems – how about really intelligent life?

A Modest Proposal

The genus Homo appeared on planet Earth about 2.5 million years ago, the species Homo Sapiens appeared roughly 800,000 years ago, and the subspecies Homo Sapiens Sapiens (double-wise?  Hah!) (that’s US, modern humans) about 200,000 years ago (as I am no paleoanthropologist, I can be excused for mis-stating the dates, but that does not affect my argument).  We modern humans traded hunting and gathering for the domestication of animals and agriculture a mere 12,000 years ago.  The Industrial Revolution (beginning with steam power) began less than 300 years ago, and the wide-spread use of electricity took place over decades from the late 1880’s through the Great Depression (still on-going in many places in the world).  Before that transformative transition, all of your ancestors knew what the Milky Way* was (they could see it, even if they didn't know what it was!) and they could see it every night.  And the stars that they could see with the naked eye!  Not hundreds, not thousands, more like 100,000 - uncountable.  The advent of Cell Phone technology in the 1990’s and of “Smart Phones” (Blackberry, iPhone and Android) in the last fifteen years signified the last nail in the coffin of our being able to differentiate work from play and rest, and our entire dependency on Industry, Electricity and Technology.  When you go on vacation today, even if you spend it on Tahiti; do you really go on vacation, are you really isolated in any real sense from your workaday world?  Even there, a real night sky overhead, do you ever look UP?  What is the difference between you and a robot that mimics you?  Today, we "know" the difference, but the tomorrow when we won't see the difference is not that far in the future.

Is Ebola the Coming Plague?

I am not a trained physician, I do not work in the health profession, and I am not a student of biology.  So, what I am about to write may be a small pile of shit.  Nonetheless.

The “Black Death” (the second outbreak of the bubonic plague, ca. 1340 – 1400) took 1/5 to 1/3 of the population of the entire world at the time (some 75 to 200 million souls).  The 1918 flu pandemic took 20 to 100 million souls worldwide.  These figures compare frighteningly well against the casualties of our most horrific wars.
