Semantics and the lowest common denominator

I have been interested in books, TV shows and lately Podcasts about supernatural, paranormal, extraterrestrial and other such stuff for a long time. Lately I have been listening to lots (lots) of Podcasts dealing with all sorts of topics somewhat from the fringe. Sometimes the host(s) of the show and the guest are very careful how they talk about a subject. Often, though, words (or memes) such as reincarnation, near-death-experience, ghost, alien, UFO, etc, are dropped as if they (and we, the listener) know exactly what that is. The guest sometimes talks about the afterlife in such specific ways as if they had just finished a college course on it. Of course that kind of language usage and specific words and terms dominate our daily life. Terms, such as food, sleep, super market are spoken and used in written form and usually they are understood close to what they were intended to mean.

Quickly, though, we come to more dubious words that are used in everyday language by a large number of people and on the surface we go: “Sure, I know what a conservative (or liberal, or progressive) is.” Except, that you have two different people trying to explain it and their understanding will most likely not overlap much. How about the word god? How about the phrase “I believe in god?” What does that mean? This could conceivably take a lifetime to explain – and the explanation would again contain usage of terms that are assumed to convey clear, unambiguous information but in turn require more explanation.

In a way, isn’t this what the working body of science has tried to mend? When ‘normal’ people talk about a theory they usually mean something they think is an explanation – not necessarily backed by any evidence or any logical or rational path of reasoning. In science the word theory has a very specific meaning and is clearly defined. It seems science strives to implement very strict definitions of the language and terminology it uses. That means, ideally, that those who have studied specific scientific fields can communicate in very precise and unambiguous terms. While this is the ideal situation, more often than not it has turned out that established scientific fact (along with the terminology) was simply wrong. Luckily, science can admit errors and correct them

Now we get to the fringey stuff, where two folks talk about reincarnation or ghosts as if they both knew exactly what is being talked about, assuming that they are also talking about the same thing, and (before I forget) that those things actually exist. Can there even be a meaningful discussion under such circumstances? Again: the thing that is being discussed is most likely not the same for each party, often one or both of the parties have not experienced anything like a ghost personally but get their information from other sources, who also use terms and words which are not defined but are taken as truth. This is how huge pyramids of fringe theories are built on hot air.

You could claim that much of the scientific body of work and knowledge is equally built on hot air. Perhaps it is, I don’t care, but the rigorous definition of terms and relationships plus a high internal consistency amounts to something and has changed material reality. It’s akin to a bunch of musicians knowing the same tune in the same key, agreeing on how to start, when to modulate to where and how to end. It may all be made up from hot air, but it works. While you put a bunch of people together, some who may not know how to hold their instrument, you tell them to play a tune that everybody should know from listening to the radio, nobody counts off, nobody knows the key (or even what a key is). What you’ll hear could be very adventurous, maybe interesting but probably won’t resemble the song they were supposed to play. And if they try it again it will sound totally different.

I guess here comes the clincher. Is it possible that nothing has any meaning unless it is given meaning by what or who consciously experiences it? And then that experience will be incredibly deep, valuable and detailed until the experiencer tries to explain it to someone who hasn’t experienced exactly the same thing – at which point the experiencer will start accepting the verbalized, official version him or herself. Makes you wish for something like telepathy, where an experiencer could transmit the experience directly to somebody else….

Some podcasts I really like (warts and all):

Skeptiko

Mysterious Universe

Paranormal Podcast

The Paracast

and on the skeptical side:

The Skeptics Guide to the Universe

Geologic Podcast

Big Picture Science

Skepticality

There are of course a lot more but the day is only so long….

Rebooting Reality, part 1

I have often wondered what would happen if we could start over with something. For example language. Let’s say we wind back time to the beginning of the development of language – assuming, for the moment, there is such a thing as a starting point. If we let it run again from that moment how would it develop? Would it develop pretty much along the same lines? Totally different?

Now, take something like Mathematics. Push the RESET button. Do we expect the exact science of Mathematics to develop the same way it did? Maybe it will develop along different ways but still end up with the same formulas, constants, rules, etc. One would expect the latter if Mathematics is as universal as it is usually made out to be. Wouldn’t we feel utterly betrayed if somehow these RESET mathematicians came up with a consistent, workable and applicable system that is totally different from ours?

Think of a house. Over its lifetime the owner will put on a new roof. Floors might be ripped out, walls torn down. Additions might be built. A second floor added on. When you get to the thought of adding passive and active energy savings measures such as insulation, windows that reflect the sunlight at just the right time of the year and let the light through at other times, solar panels? geothermal heating & cooling? – you get the idea – one might find that the original dwelling was built at a very odd angle to the sun that doesn’t allow easy usage of sunlight. You might find out that there is not enough room to run the water pipes from a roof installation of solar hot water panels – the rafters might be too weak to carry the weight anyhow. There comes a point when the owner realizes that if she really wants go ahead with all the upgrades it would be much more efficient to start over. Tear the old house down and build a new one – doing it right this time.

Another interesting target for such speculations is the wide field of Physics. Especially Theoretical Physics. This is a field which interests me tremendously yet I must admit my actual understanding of the whole thing is pitiful. I tend to read these really cool articles in Scientific American and various other magazines. While I read I go “Yeah, right. I get it this time. Makes total sense.” But as soon as I am supposed to tell somebody else in my own words what the article was about I can’t put it back together. What is probably the most outlandish aspect of it is that it’s all so small. Not only can’t we see any of the quarks, leptons, let alone force carriers such as photons. Somehow all of that seems so removed and irrelevant to our everyday lives. And yet the interactions between all these different forces and particles produce our reality. What if we press RESET for Theoretical Physics? One would imagine that while we don’t know how, when and by whom various effects would be discovered and what language would be used to express this knowledge there still would be someone to figure out the theory behind electromagnetism (James Clerk Maxwell did it in our reality). You would think that somebody would eventually uncover E=mc squared although we don’t know what mathematics she would use to describe it. Could it be that the building of Theoretical Physics might be constructed in a different order and thereby would actually come out differently? Impossible, you say, physics describes the underlying rules of reality but maybe our physics only describe the tip of a huge iceberg. RESET physics and another tip of the iceberg might be sticking out of the water.

One subject of interest to me is music. How could music develop differently after a total RESET? (Assuming of course that music would actually develop in the first place.) Since music is a subject I have a bit more expertise I want to offer an idea I have been elaborating on for a few years now. Assuming a piece of music – for the moment this could be one of the simpler, shorter and clearly structured compositions of J. S. Bach – we know what theoretical background it comes from. We know the key, the meter, how the melody relates to the bass notes, how the notes in between create a harmonic movement. We know how, through the circle of fifths, the major and minor keys relate to each other. Seemingly the composition of the piece is more or less an application of general rules mixed with personal preferences on the musical raw material which has been fine-tuned and formalized over hundreds of years. So, now assume that some alien digs out a recording of that piece. No other materials are found. No reference points to what culture that music came from. The piece of music clearly has structure. It clearly works according to certain rules. But which rules? Can the alien figure out by that piece of music alone what the underlying system of rules and customs that led to its composition were? Could it actually be that this alien might come up with a totally different underlying system for the creation of the piece? I guess if these aliens find more music they will develop a better and better handle on what concepts it’s based upon. Or really? Maybe after a piece of music has been composed or created in some way it’s roots are best forgotten. On the other hand I wonder if it could stand all by itself, apart from the culture that brought it forth.

Finally, for part 1 of this train of thought, think how science actually developed over thousands of years from mythology, religion, superstition, etc. People wanted to know. What knowledge they didn’t have they filled in – by connecting the visible dots, consequently ignoring countless little details in between. Obviously nowadays we know much more about the details in between the dots. And much of it actually seems to be correct since we can use the theories we came up with and reliably predict how certain things in reality will behave. We use these theories to work out what will happen if we put together two chemicals in specific quantities We use them to calculate how to construct rockets to deliver satellites into space and figure out where to put them so they appear to stay over the same geographical location all the time. We use them to program the algorithms that let our GPS navigation systems use these satellites to guide us through big city jungles of one-way streets. So the theories we have work on various chunks of reality. None so far seems to pull it all together. There are still dots hidden and one wonders if in a RESET reality other dots might be found first.

UFOs have landed – and they are….WTF?

After listening to the 11/23/2008 episode of Tim Harold’s  Paranormal Podcast featuring an interview with Stanton T. Friedman I had some more thoughts about the relationship of the UFO phenomenon with Science.

I want to say upfront that while I more often than not highly disagree with Tim Harold’s guests he is an excellent interviewer who somehow manages to keep a straight face (or tone of voice) while his guests tell the most outlandish stuff. I have heard Mr. Friedman interviewed on other shows before, I have checked out his website and viewed some of his video material on youtube. While I actually agree with him and many other ‘fringe’ or paranormal people that there might be more to a certain phenomenon than current scientific knowledge can explain I find the way they on one hand condemn scientists, universities and research in many fields when it contradicts their ideas while on the other hand eagerly striving to be scientific themselves to be a little inconsistent. Alright, I think I understand where they are coming from. People like Stanton Friedman used to work in a scientific field. They believe the stuff they research now is for real, too. What struck me with that particular interview was that Mr. Friedman spent a whole hour telling how close-minded scientists are when the subject of UFOs comes up. He specifically mentioned Brian Dunning, who produces the excellent Skeptoid podcast. I have listened to every episode of Skeptoid. I find them well reasoned, thoroughly researched and occasionally disturbing (I am a vegetarian and the episode about organically grown food didn’t go down easy.) Mr. Friedman also mentioned Seth Shostak from the SETI Institute who produces a podcast called ‘Are we alone’. The SETI Institute listens for intelligent signals from outer space (remember the movie ‘Contact’?) The podcast deals with scientific topics around that. I have learned much about robotics, astrobiology, physics, etc. listening to that show. Stanton Friedman called the search for extraterrestrial life a ‘religion’.

When I found out about podcasting I was surprised how many science shows there were. Scientific American offers two podcasts. Groks Science Radio Show is a great podcast with different guests each week. Not to forget The Skeptics’ Guide to the Universe, Skepticality, Geologic Podcast, Quirks and Quarks. There are many more but they don’t all fit on my iPod. The days are too short to catch them all. All of them have one thing in common: I actually learn something from them. And they actually talk about real things, or sometimes hypothetical things. It’s about stuff that has something to do with my reality. The people on these shows are not whining about not being accepted by the general science community (probably because their research has passed the peer review process?) Funny, too, when they talk about the fringe stuff (at least they do on the skeptics’ shows) the consensus is that if there was a real flying saucer or compelling evidence for ESP or life after death scientists wouldn’t hesitate to probe the subject in depth. Anyway, to make it short: podcasts or TV documentaries, books or magazine articles dealing with UFOs have often been about how serious scientists ignore the evidence for alien visitation accompanied by a few blurry or inconclusive photos, and the demand that more research needs to be done (and that the US government must release all the secret documents pertaining the Roswell incident.) I haven’t really learned anything new or conclusive from the UFO guys. And it’s not that anybody prevents people like Stanton Friedman from producing their own weekly podcast. I might actually tune in, in search for new information but for some reason I think it might be a bit repetitive after a few episodes when the reality I live in somehow turns out to have no relationship with what they talk about on the show. It just doesn’t hold much water to see a light in the sky and to extrapolate from that observation that grey aliens and reptilians are at war, etc. I know it’s oversimplified but my call goes out to the UFO folks: If you have real things to report about then produce your own podcast and convince me with compelling evidence.

Science for the non-scientist

I am a frustrated, castrated, suppressed mathematician, physicist, rocket engineer. I was born in 1960. Ok, Sputnik, was three years earlier. But when in 1968 Apollo 8 traveled around the Moon my granddad had already started giving me science books for birthdays and Christmas. The books about the U.S. space program were my favorites. From that time I have kept many notepads full of childish doodles of spaceships and astronauts.

When, on July 20 1969, just three days before my ninth birthday, Neil Armstrong set foot on the Moon I was the only one in my family who staid up late to watch the live broadcast on German TV.  Consequently, I learned all I could about the US space program. I knew all the Astronauts by name and had see-through drawings of the Saturn V internalized. There was no doubt in my mind (and my parents’) that I would become an Astronaut, a rocket engineer or at least a pilot of some sort.

At one point in my teens puberty set in, the last two Apollo missions were canceled and surplus materials used in Skylab and somehow all talk of going to Mars next, or setting up a permanent moon base had gone away. Not only did the first girl I fell in love with not care for me but I was old enough to be asked “So, do you know what you want to be when you grow up?” At that time I started to realize that this question was somehow linked with money. While I had always been interested in Physics, Chemistry and Mathematics I just wasn’t able to get good grades in these subjects.

Around age 14, by sheer coincidence, I started playing guitar and just a few months later I played my first gig and got paid for it. Not much but enough to encourage me to pursue music. My interest in science and engineering never went away, With proper guidance I might have finished Gymnasium and gone on to study – University was free in Germany, for crying out loud! But I went the artistic way. I kept some sort of contact with my scientific interests by subscribing to various magazines. TV shows about technology were still my favorites and I developed an appetite for the literature called ‘Science Fiction’. In the course of my late teens and early twenties I drifted away from pure science – while my ex-classmates became doctors, chemists and biologists – and was consuming SF pretty much exclusively. While I actually started supporting myself by teaching guitar lessons and playing gigs and recording sessions every once in while the old science connection stirred in me. But there just didn’t seem to be a way to change professions (in retrospect of course I can see many junctures at which it would have been easy to switch, old people can be so much wiser.)

In 1983 I had my first practical exposure to a real computer. A Commodore 64, when I started to work part time at a friend’s computer store. There the old passion surfaced again. Learning programming, first Basic then Assembly, was such a blast. Again, I could have easily switched careers. At that time computer knowledge was in demand. Again I missed the boat and struggled on as a mediocre musician. At least computers became a big part of my everyday life and that kept the old interest in science and technology alive.

In the mid 80s I started to become interested in more, shall we say, esoteric topics. I had discovered books about past-life regression, reincarnation, UFOs. While I don’t know if I ever really believed any of this I still consumed large quantities of books dealing with these subjects. This phase lasted roughly about 10 years until after I had relocated to the US. Out of a melange of SF books and metaphysical literature I had been reading in that decade came the strange realization that:
#1, somehow there wasn’t much of a difference between the Science Fiction and the books about reincarnation, conspiracies, etc,
#2, the metaphysics books had vastly different and conflicting views from each other about reality and I started wondering where exactly these authors had their information from
#3, I had been an Atheist for most of my life and slowly I came to the conclusion that believing in UFOs and many other ‘unproven’  supernatural claims actually falls in the same category as Religion: You believe because you have faith and not because there is evidence

Within a short few years I started reading pure science books again and started a subscription to Scientific American. And now, as I am working the exercises from the ‘Idiot’s Guide to Geometry’ and am learning about the Scientific Method I realize that I still want to be a Scientist, engineer or something like that.

And that finally brings me to the point of this blather: How can someone who is not a PH.D. contribute to Science? How can you help building a base on the Moon and landing a man on Mars without working for NASA? Ok, I can always contribute money to the Planetary Society or the Mars Society. But that’s not really what I mean (although I am a member). How can I contribute, without being a physicist, an engineer or a billionaire? Are there more people like me out there. People who were very interested in Science for a while and then the needs of a job and family forced them unto a different path?

It now seems to me that one of the biggest things would be a community for people like me. Not quite geniuses and not quite idiots.
