- THEY DON'T GET NO RESPECT
- by Kent Harker
-
- [Since its inception in 1948, UFOlogy has sought scientific
- respectability. It has gained some when its ranks have added names
- from the scientific community. Dr. James Harder, professor of
- engineering at UCB addressed BAS monthly meeting (please see
- Michael Sorens's article on page 5 for the details of that
- meeting).
-
- I sent Dr. Harder a copy of my article in early February and
- invited him to offer a rebuttal which would be published unedited
- in "BASIS". No response.]
-
- Dr. Harder is a respected, qualified member of the scientific
- "establishment" who finds himself in a minority. Of course, there
- is nothing disreputable in this, as Dr. Harder recognizes. He
- merely views himself as in the avant garde. He pointed out that new
- discoveries are usually opposed at first and cited examples.
-
- But there was a key statement by Dr. Harder that stopped me cold.
- He said, "Observation always supersedes theory." The implication
- is clear insofar as UFOs are concerned, and his dictum is correct
- as it applies to the scientific method. If theory states that a
- bird with a wing-area-to-body-weight ratio less than 2.33 CANNOT
- fly, observation of a hummingbird aloft with a ratio of 1.91
- supersedes the theory. It is a counter-example, and the theory must
- fall or be revised.
-
- As Dr. Harder applies this to the question of alien presence, he
- makes a couple of -- unwarranted, I think -- assumptions. One is
- that skeptics have some theory that there cannot be an alien
- presence. The most critical of UFOlogy (Robert Sheaffer, for
- example) do not take such a stance; Sheaffer could be persuaded and
- he will tell you the kinds of things it would take to change his
- mind.
-
- But the most crucial, and, I think, the most unreasonable of
- Harder's assumptions, is that UFO observations are reliable. In
- fact I found it astonishing that an individual of Dr. Harder's
- preparation and standing could so blithely allow the definition of
- "observation" in the strict scientific sense to be applied to what
- has been (and is) reported in UFOdom. SCIENTIFIC observation
- requires rigorous standards and controlled conditions.
-
- Let's see if that scientific standard is as carefully followed in
- UFOlogy as would be taught in Dr. Harder's classroom at UC
- Berkeley. How credible is the eye of a human observer -- an
- eyewitness -- when highly emotional phenomena are involved?
-
- At the dedication of the canonization of Saint Charbel, the first
- Lebanese Catholic to be sainted, there was eye-witness testimony
- that the arm of the memorial statue raised as if to bless the
- assembled thong. It was not one or two that attested to this
- miracle -- hundreds did so. Now, molecular theory states that the
- particles of matter, irrespective of how apparently rigid the
- nature of the material they compose, are constantly in random
- motion. It is essentially unthinkable that all those billions of
- billions of molecules just happened to have moved in the same
- direction all at the same time, resulting in the marble arm being
- elevated.
-
- So the Church would call it a miracle, and we would have to agree.
-
- If.
-
- If the observations were reliable. I have no doubt whatever that
- all those observers would pass a whole battery of lie-detector
- tests and that any hypnotized participants would "remember" that
- they, too, had witnessed the same event. I am certain that all of
- those witnesses believe what they alleged and just as certain Dr.
- Harder would not disagree with me.
-
- The reliability of eye-witness accounts is a subject of great
- psychological and legal concern. It is so easy to destroy the
- testimony of an eye witness in a criminal case that both
- prosecution and defense are very cautious about how it is done. A
- recent case comes to mind that was aired on "60 Minutes" in which
- a man was tried and convicted on eye-witness accounts. He was
- poorly defended (a public defender) and Safer and crew found proof
- that the man was not even near the scene of the crime at the time.
- The eye-witnesses were not lying. They were honest people --
- honestly mistaken when they positively identified the defendant.
-
- What about when the account is second-hand? Would this be
- acceptable under the evidential requirements of a science lab?
- Particularly when the admission of such observations might require
- a significant change in the scientific model? Are we ready to
- jettison some deeply-entrenched, well-tested physics that says
- large masses passing through the sound barrier must be accompanied
- by a sonic boom when a "competent observer" (an Air Force pilot)
- files such a report in which a UFO accelerates at an estimated 100
- Gs without a sound? Do we wish to ignore those same laws
- (Einsteinian physics) that require anything plastic to be quickly
- converted to mashed potatoes in such an acceleration?
-
- We can question the theory or we can question the observation. As
- long as the observations are made in less-than-controlled
- circumstances, the laws of parsimony require suspicion of the
- latter before we set about turning things upside down.
-
- Dr. Harder's stance seems to rest upon two kinds of observation:
- Typical eye-witness reports and hypnotic recall. It is my
- contention that Dr. Harder is not expert in either of these areas,
- and that he is liable to heavy errors because of that lack of
- expertise. (I have no doubt that he may be an expert hypnotist, but
- this is not what I mean. I refer to the domain of psychology, brain
- physiology, and related bio-psychological fields.)
-
- The problems of eye-witness accounts are then exacerbated by the
- problems of recall. The public has a notion that the mind is like
- a tape recorder, and if one can successfully (via hypnosis, for
- example) rewind the tape, what comes out when it is played back is
- 100% accurate. How does observation of the I-saw-it-with-my-own-
- eyes variety stack up? Here is a tiny sample of the documented
- cases in which (1) the reality was known, and (2) the observational
- accounts of the event have been carefully recorded:
-
- The planet Venus has been cleared to land at some major airports,
- shot at, and mistaken for a freight train.
-
- On March 12, 1978 (Sheaffer, 1981) thousands witnessed a "fleet of
- UFOs" with a mother ship (or two, three or four mother ships,
- depending upon which witness) about the size of a 747 was headed
- on a collision course with a Brazilian military base. The UFO
- armada leveled off at 2,000 feet (or 500 feet according to some)
- and then disappeared. It was reported so low that one observer, a
- pilot, saw portholes in the cigar-shaped vessel.
-
- Astronomers very quickly documented that it was a large and
- brilliant fireball meteor.
-
- Night-flying advertising aircraft are often mistaken as UFOs and
- usually described as saucer-shaped, enormous sized, and emitting
- a flood of brilliant, continuous light, and moving slowly, or
- hovering, without sound.
-
- Weather balloons, flying at altitudes in excess of 60,000 feet are
- reported to be enormous UFOs hovering at 1,000 feet in every color
- imaginable.
-
- An important hoax conducted on March 28, 1970 ("SI", 1980) at
- Cradle Hill, England, a popular gathering place for UFO observers,
- showed the extent of eye-witness unreliability. This case is
- important in that the circumstances were carefully controlled.
-
- At 11 p.m., a 12-volt, high-intensity purple spotlight was directed
- at Cradle Hill from 0.75 miles away. It was stationary, and turned
- on 5 sec., off for 5 sec., and on again for 25 sec. At Cradle Hill
- a collaborator switched on a phony magnetic-field sensor (many UFO
- enthusiasts expect a strong magnetic field as a secondary
- confirmation of UFOs) at a predetermined time to synchronize with
- the light, and the field-detection buzzer was activated so that the
- group of about 30 UFO observers thought a strong field was present.
-
- The collaborator then took two exposures of the light over two
- previously exposed frames, each containing a fake UFO and then took
- two real, time-lapse pictures. There were street lights and several
- other reference point in all exposures. Negatives and prints were
- turned over to various UFO groups throughout the world.
-
- The first two photos showed the fake UFO in two different positions
- far to the right of the spotlight (recorded by the second exposure)
- with a much higher light intensity than the stationary purple beam.
- All of the eye-witness accounts corroborated the photographic
- evidence, stating that they observed the object moving, that it was
- very bright, and that it was visible for one to one-and-a-half
- minutes.
-
- The perpetrators kept the hoax secret for two years, during which
- time the photographs were extensively analyzed and declared to be
- authentic. One specialist, Pierre Guerin from the Astrophysical
- Institute in France, declared, "In my opinion there is no question
- of the object photographed being in any possible way the result of
- faking.
-
- The history of UFOlogy is one in which these same scenes are
- repeated with dreary regularity.
-
- So what about the other side of Dr. Harder's observations, the
- hypnotically-recalled experiences of UFO abductees?
-
- The literature on the validity of hypnotic recall is usually in
- professional journals; those not in the trades, as it were, would
- have to exert special effort to follow the work that has been done.
- The information that has come out for public consumption appears
- in the context of court cases because the judiciary has had to
- decide if such testimony is admissible. The verdict is that there
- is so much subjectivity that serious errors may be introduced, so
- hypnotic recall is inadmissible in a court of law. Why Dr. Harder
- allows it in a science laboratory is something that needs to be
- explained.
-
- Some of the best analyses for public consumption have been done in
- the latest issue of the "Skeptical Inquirer", and the reader is
- urged to study the full account of the neuro-psychological problems
- involved with hypnotic regression in that publication.
-
- A great summation is embodied in the statement from U. of Kentucky
- psychologist Robert A. Baker's article ("SI",1988) "The Aliens
- Among Us: Hypnotic Regression Revisited" in which he said,
- "...hypnosis is a situation in which people set aside critical
- judgment (without abandoning it entirely) and engage in make-
- believe and fantasy; that is, they use their imagination." Baker
- goes on to point out that if the hypnotist is sympathetic and
- supportive, the suggestible patient will (unconsciously) provide
- whatever he or she perceives the hypnotist wants.
-
- Dr. Harder might counter with a case he reported in which a mother
- and daughter related the same abduction incident in great detail
- under hypnosis. The women had no memory of any abduction in their
- conscious state, so they could not have collaborated in any way,
- according to Harder. He offers that the close agreement on the
- details tends to rule out a prosaic explanation. I agree with
- Michael Sorens when he suggests we leave it to "BASIS" readers to
- see if a UFO abduction is the only other possibility.
-
- Alas, UFOlogy has not advanced very much since the first flying
- saucers were observed wafting through our atmosphere in 1948. J.
- Allen Hynek, astronomer and pre-eminent UFOlogist, died without
- seeing a realization of his prediction that UFOlogy would soon
- achieve scientific respectability, and UFOlogy is in about the same
- state as it was when he became a believer. The supermarket tabloids
- and specialty groups generally remain the principal repository of
- UFOmania.

- The widow and kids of Carl Stevens get top honors. The "Mercury"
- took the story from the AP wire about the Stevens family. Carl, you
- see, has not been alive since 1979. But his corpse was kept in the
- upstairs bedroom of the home nevertheless. Each day Mrs. Stevens
- faithfully changed his clothes and bedding. Friends and relatives
- were told Carl was sick, and they were never allowed to see him
- because "they had a black soul" (which would presumably interrupt
- the healing process). Carl's two children appeared to be well-
- adjusted teens, both of them honor students.
-
- When the sheriff finally got a court order to enter the home, they
- found Carl neatly tucked in his fresh clothes and bedding a mere
- skeleton with a thin covering of skin. (There were no details about
- any severe B.O. Mrs. Stevens might have noticed on hubby.) The
- Sheriff, never one to overstate the facts, observed, "Let's just
- say they have abnormal belief in the power of healing."

-
- MATH PRODIGIES?
-
- Skeptic Dr. Philip Rice sent an article from the "Chron." that
- caught his eye. We have all heard of or witnessed the wonders of
- the so-called lightning human calculators -- those whizzes who can
- compute faster then their electronic counterparts. There is nothing
- paranormal about this ability -- but. But, within limits. Philip
- wondered if there were something "rotten in Denmark," as he put it,
- to the whole thing when he read that the Institute of Noetic
- Science (INS) was working with some of these remarkable people, so
- he sent the article to "BASIS".
-
- The article documented an Indian woman, a Ms. Devi, who performed
- some prodigious mathematical feats: "The cube of 121? `One seven
- seven one five six one,' she replied instantly." This is not really
- very spectacular if one knows a few tricks. 121 is 11 squared, so
- it is the same as 11 raised to the sixth power. There are short-
- cuts to do multiples of eleven.
-
- Devi was asked if she could only work with whole numbers and so she
- asked for a fraction. She was given the task of extracting of the
- third root of 12,812.904. "`That,' she said without hesitation,
- `is the third power of 23.4."
-
- As a former mathematics instructor, this editor was astounded at
- the number and its third root.
-
- Cubing 121 is no big deal. Knowledge of a few mental tricks, some
- studied practice and most can perform arithmetic operations very
- rapidly. Going the other direction is another matter, i.e.,
- extracting higher roots. The thing that is more remarkable than
- Devi's alleged power to perform such feats is the choice of a non-
- integral number with rational roots. (Integers are positive and
- negative counting numbers, and rational numbers are those that can
- be expressed as a ratio of integers. The square root of three, for
- example is irrational, i.e., it cannot be expressed as a ratio of
- integers.) In fact, the probability of a RANDOMLY-CHOSEN, non-
- integral number whose cube root is rational is effectively zero.
- The "selected" number is virtually certain to have been a plant.
-
- Tricksters hope we won't look in from the back end, but that's
- exactly what Dr. Rice did in his comments to "BASIS". He thought
- it a little strange that the root is sequential, i.e., 2-3-4. Take
- .234, 2.34, 23.4, or 234, cube it and then feed the answer in
- reverse through a plant. Mnemonics are the most likely explanation
- here, not phenomenal ability. Philip showed how easily the same
- scheme can be worked with other three-digit sequences.
-
- "BASIS" then wrote to the "Chronicle" with these analyses and
- called the INS to see if they would be interested in tests under
- controlled conditions. We don't expect any of our counter to this
- nonsense to appear, and, as we further expected, the INS will not
- return any calls. After the fourth call in as many days, their
- answering machines were off and we were able to talk to a human.
- Her only comment was that remote viewing had been scientifically
- demonstrated under controlled conditions and ESP was an established
- fact. She seemed genuinely astonished that there were any people
- who disbelieved.
-
- Our thanks to Dr. Rice and the rest of our alert readers. The media
- will continue hearing from us on things like this, and we think
- they will begin listening if we keep up the heat. Keep sending in
- the nonsense, and continue writing the newspapers.

- LUCKY FOLLOW-UP
- by Richard Cleverly
-
- After my article on the psychic who offered, in full-page ads,
- lucky numbers for only $1 (P&H), I saw the ad again on the back
- page of the family supplement insert of the Sunday paper. Same
- lady, a Madame Daudet. -- all good psychics are Madame, with an
- "e", or Reverend.
-
- Her ad promised "lucky numbers" that would bring untold wealth for
- only a buck. What do I have to lose? Well, a dollar. But that's
- only for P&H. In my first article I reasoned a sophisticated
- scheme, so I decided to check things out by sending THREE letters
- to the good Madame, and lest she track me with duplicate addresses,
- one was from my P. O. box, another from my home, and a third from
- my office.
-
- I was unprepared for what I got.
-
- The $1 was for P&H all right -- a bulk-mail envelope with cursive
- writing on it stating, "Here is the personal and confidential
- information you recently requested." I wondered if the carrier
- thought I might be into porn. It was so full of personal and
- confidential information I couldn't find the number she promised
- me. I spent almost thirty minutes (I know, I wasted the dollar, and
- now I'm throwing good after bad by spending time actually expecting
- to find what she promised, but this is a Cause, you know) before
- I found it.
-
- In what looked like a hand-written note addressed "Dear Friend,"
- she said she hoped she could call me her dear friend because as
- soon as she received my inquiry she began researching my aspects
- and had found some truly remarkable things. Deeper in the packet
- was a titillating sample of the Secrets of the Ages, prepared "Just
- for you" (but addressed "Dear Seeker of Happiness and Good
- Fortune"). If this had cost me more I would not share the intimate
- things she gave me with the rest of you raving skeptics. What I am
- about to reveal is at great peril to my good fortune. Ah, the
- sacrifices for the cause of Truth.
-
- "Your letter to me was one of special communication. As soon as I
- held it in my hand, I felt a sense of urgency, which made me
- consider your case on a priority basis." she continued.
-
- Just go to your bank, put a crisp dollar bill on the counter,
- informing the teller you would like to make a deposit, and see if
- you get that kind of respect. Come to think of it, it did take her
- about three months to respond. Then again, it takes time to do that
- kind of specialized research on my aspects, the kind you would only
- do for a dear friend. Well, Mme. Daudet promised she would soon
- reveal my special number that "shines with particular brilliance
- in Your [she even capitalized my personal pronoun, thank you]
- astral heaven."
-
- Now this is where I am violating a sacred trust she placed upon me.
- She said, "Part of your most important number is 2, and its
- complementary 3." In fact it is so personal and confidential that
- "it must never be revealed to anyone else, and if you do, you run
- the risk of losing part of its power."
-
- A 2 and a 3. Two? Twenty-three? Thirty-two? 3,322?
-
- I don't suppose I should feel hurt if everyone else on the block
- got those same numbers. I mean what with only 10 digits it surely
- wouldn't mean there is anything impersonal that we millions happen
- to share the same miracle numbers. Just, please, share your lottery
- prize if you win it with my numbers. But these aren't my ONLY lucky
- numbers. She has more for me. I remember now that she didn't say
- in her original ads she would give me ALL my lucky numbers for the
- $1.
-
- She was so taken with my case that she was "inspired to continue
- studying your personal case, and I have found that my first
- instincts have been confirmed: You are entering a truly excellent
- period of your life, a solar period, a period of warmth and
- brilliance."
-
- To get the rest of the numbers that go along with my two lucky
- numbers, and to get a complete numerological horoscope to help me
- take full advantage of the opportunities that await me in the truly
- excellent period, I need to RUSH the enclosed validation card to
- her together with my check for $35. Of course, she will accept
- Visa. Whaddaya expect for a buck? Bon Dieu! I almost forgot. I get
- a special surprise if I respond within 10 days: "A miraculous
- Lourdes Medal from the sacred shrine at Lourdes, France."
-
- Well, I passed.
-
- One week later. My box is full of mail from astrologers, psychics,
- and spiritualists. Norvell, "the greatest Astrologer of our time"
- promises -- guarantees -- he will give me lucky numbers. (The guy's
- sharp. He just guarantees he'll give me the numbers, not that they
- will be lucky.) The Lottery Research Center in New York sends a
- package that has so much printing on the envelope I wonder if there
- is anything left to say on the inside. "This privileged information
- is being released to you immediately: (Remove Contents)."
-
- I was glad they reminded me to remove the contents in case I had
- forgotten he had more to say.
-
- I don't know what Norvell would think about it, but in the same
- delivery was Lynne Palmer's solicitation and it says SHE is the
- "world's most successful astrologer." Since she doesn't use upper
- case on her title, maybe that's how she and Norvell sort it out.
- She MUST be better, because she has more writing on her envelope.
- Lynne is the clear winner in the writing-on-the-outside category.
- (I wonder if there might be some law that says the importance of
- the material on the inside is in inverse proportion to the amount
- of writing on the outside.) There are about six postcards from
- numerologists in the Minor Leagues -- they don't have the budget
- for the big mailings.
-
- This is the ultimate indignity. The Gaul tart had the gaul to sell
- my name on mailing lists. Probably helped her cover her losses for
- the measly dollar I sent her. Come to think of it, it was three
- dollars, and I never did hear on the other two. Her data base must
- sort on name, because I used the same name and birthday to see if
- she would give the same computer printout for the same birthdays.
-
- Why I ever thought there would be anything as sophisticated as I
- suggested in my first article is beyond me now. Sorry.
-
- Madame Daudet has the lucky numbers, all right. She's got mine and
- all the rest of we suckers that mailed in our $1. Au revoir, money.

- JANUARY MEETING
- by Michael Sorens
-
- At the January 26th meeting, held at the El Cerrito Library, we had
- the pleasure of hearing Dr. James Harder give a most eloquent
- presentation on UFOs. A professor of engineering at UC Berkeley,
- and a Fellow of the American Association for the Advancement of
- Science (AAAS), Dr. Harder proclaimed himself a skeptic, while at
- the same time espousing the belief that UFOs do, in fact, exist.
-
- He began his talk by reminding us that there were skeptics as late
- as 1902 who refused to believe the Earth was round. And that there
- were skeptics, led by the pre-eminent physicist Robert Miliken in
- 1946, who declared that rocket travel to the Moon was impossible.
- he hoped that we, his audience, were not those kinds of skeptics.
- Dr. Harder indicated that he himself was the kind of skeptic that
- required evidence to support a theory.
-
- Citing a comparison he made to astrologers, it would be a straight-
- forward task to test whether the "cosmic twin" theory holds any
- water (i.e., two people born at the same time, same latitude, etc.,
- and hence under the same sign will turn out similarly). One has
- merely to examine birth records of a certain area from 15 or so
- years ago to locate potential cosmic twins, then examine the
- current school records, criminal records, etc., of those same
- people today. This type of study will provide a small, and perhaps
- significant, amount of evidence relating to astrology.
-
- Dr. Harder challenged that theory is useful, but observation and
- experiment take precedence. In the well-known Trindade case, a UFO
- was observed by approximately one hundred witnesses who were on a
- boat in Brazilian waters. Photographs were taken, quickly
- developed, and shown to the eyewitnesses, who generally agreed
- that, yes, that was what they had seen.
-
- Dr. Harder conceded that it may not have been a UFO; perhaps, he
- suggests, it was mass hysteria. But why, he contends, did it affect
- the film as well as peoples' minds? It is somewhat harder to
- dismiss his notion that just because the photographer was a
- specialist in trick photography is no reason to assume that trick
- photography had been used. (This strikes me as akin to going back
- to a used car dealer to purchase an additional car, after your
- mechanic informed you that the seller must have been aware of major
- problems with the first vehicle you purchased from him.)
-
- There have, in fact, been alternate explanations about what
- occurred: Prominent skeptic Robert Sheaffer cited a version of the
- story that purported that only the photographer and a friend saw
- the UFO. They drew the attention of bystanders, but the craft had
- flown off. Going off to a darkroom, they later emerged with their
- pictures. This does tend to leave just a bit of room for skepticism
- in this particular case. Dr. Harder later agreed that eyewitnesses
- are not the best form of evidence, but in this case he suggested
- that the eyewitness reports did constitute sufficient proof.
-
- A member of the audience contended, however, that extraordinary
- claims require extraordinary proof, a statement with which Dr.
- Harder agreed. He went further though, to inquire whether this kind
- if evidence should at least make the case worthy of further study.
-
- Another person brought out how his grandson, Eric Tejeda, was able
- to prove that UFOs have not visited us, bringing along a clipping
- from the "San Francisco Examiner" showing his grandson in front of
- his eighth-grade class while presenting his proof.
-
- Assuming an average speed of 200 miles per second, it would take
- over 18,000 years for a visitor from the nearest star to reach
- Earth. Such a generation-ship might encounter many problems such
- as raising young, having the knowledge to educate children, genetic
- problems of interbreeding, food supplies, and energy resources.
- These problems, Eric concluded, would make the possibility of alien
- visitation so unlikely that it could be considered impossible.
-
- Professor Harder conjectured that perhaps an alien technology could
- find the means to get to Earth, and if they were that advanced,
- they would probably be smart enough to learn English. And,
- perhaps, they would have good reasons for not wanting themselves
- to be seen, either because they were benevolent and wished to let
- us develop on our own, or because they were evil and were secretly
- plotting the invasion of our planet. Several in the audience
- countered that the aliens weren't doing a very good job of hiding
- if we are to believe the thousands of sightings annually.
-
- As one case study, Harder presented the following case: One of the
- designers of the P51 fighter aircraft claims to have observed a UFO
- in broad daylight, while riding as a passenger in an automobile on
- a country road. After watching it for several minutes, he observed
- it accelerate and disappear through the clouds; his later
- calculations indicated that it was accelerating at approximately
- 100 Gs and reached a velocity of 9,000 to 11,000 mph by the time
- it reached the cloud cover.
-
- Astonishingly, the craft was utterly silent. Astronomer Norm
- Sperling raised the objection to Prof. Harder that physics dictates
- that there must be a sonic boom if such an event occurred. Dr.
- Harder asked, "Is your theory better than his observation?" This
- question is left as an exercise for the reader. (Keep in mind that
- the observer had no special instruments, was riding around in a
- car, and may or may not have had a notebook. Show your work.)
-
- Dr. Harder presented a number of other interesting cases, though
- it was at times questionable whether he was making a case for or
- against the existence of extraterrestrials. Is it so unusual, for
- example, that under hypnosis two people will relate a similar tale
- about an alleged UFO incident, when they did not recollect anything
- before the hypnosis? Perhaps.
-
- If, as in this case, the two people in question were mother and
- daughter? One can hardly wonder. Harder's estimate of a 0.2%
- probability of this happening by chance alone raised red flags to
- ardent skeptic and magician Bob Steiner, along with others in the
- audience -- Harder appeared unconcerned that such a precise
- numerical figure should have some basis in calculation using common
- statistical techniques.
-
- In conclusion, I must applaud Dr. Harder for his eloquent manner
- and his ability to lead a lively discussion with unruffled
- feathers, but I must challenge him to present more rigorous
- evidence for his claims. Furthermore, science demands that a theory
- not be discarded wantonly in the face of weak evidence to the
- contrary; either much stronger evidence or a better theory must be
- offered in exchange.

- TALK IT UP
- by John Taube
-
- In a recent KGO talk show with Bill Wattenburg as host, a lady
- called, and the conversation went like this:
-
- Lady: A year ago I was told that I had cancer and I had only six
- months to live. With prayer, positive thinking, and a strong will
- to live, I cured myself.
-
- Wattenburg: I am going to cut you off right there. What you are
- saying is demeaning to the thousands of people who have died from
- that fatal disease. It is scientifically established that for a
- thousand cancer patients given a determined period of time to live,
- a small percent will enjoy remission. What accounts for a small
- percentage to be lucky had not been determined at this time. There
- is not one shred of evidence, however, that prayer, positive
- thinking, will to live, or laying-on-of-hands plays any part in
- remission. So I am going to cut you off and thank you for calling.
-
- John: I am sure that Bill would agree that when one is diagnosed
- as having a fatal disease, that person should not be discouraged
- to pray or do anything else that makes him or her feel better. But
- it must be put in perspective: Prayer, positive thinking, etc.,
- have no significant therapeutic value, but they may at least help
- the person feel better.
-
- But, some misguided pseudo-practitioners do irrevocable harm to
- people who have serious, non-fatal diseases by discouraging them
- from following the advice of their physicians. When these
- practitioners resort to faith-healing, for example, in many cases
- they make a non-fatal disease a fatal one.

- SECOND LAW VS. CREATIONISM
- by Jim Ardini, (Diablo Valley College)
- and Dick Kidd, (S. F. Community College)
-
- As physics teachers, we often encounter the assertion that the 2nd
- Law of thermodynamics precludes evolution, and, therefore forces
- acceptance of special creation. This has happened so often that we
- have written the following, which is distributed to students when
- we study thermodynamics. Scientific creationists claim the 2nd Law
- denies the possibility that a closed system can spontaneously
- become more "organized."
-
- Since life forms on earth are more highly organized than their
- inanimate precursors, it could not have arisen without divine
- intervention, they say.
-
- The 2nd Law states that "the entropy of an ISOLATED system always
- remains the same or increases." Creationists such as Dr. Gerald
- Aardsma, physicist at the Institute of Creation Science in Santee,
- CA, state it as "the entropy of a closed system always remains the
- same or increases." (See Discover, Oct. '87.) However, a closed
- system is not the same as an isolated system. To clarify this we
- begin by defining a "system." It is any collection of objects
- around which a real or imaginary boundary is placed.
-
- If we are given three objects, a cat, a dog, and a hydrant, we
- could create a system of the cat and dog, the dog and the hydrant,
- or of all three. Next we distinguish between an isolated system and
- a closed system. An isolated system is one across whose boundary
- nothing can pass, i.e., energy, matter, or force. The closed system
- to which the creationists refer is one across whose boundary matter
- cannot pass, only energy such as light or heat. It is important to
- realize that the 2nd Law refers only to isolated systems and not
- to closed systems.
-
- Next, two loose, but popular descriptions of entropy will be used:
- Entropy is a measure of the "disorder" of a system, or the
- "unavailability of energy to do work." Thus, when the available
- energy or order of a system decreases, its entropy will increase,
- and when the order exhibited by a system increases its entropy
- decreases.
-
- Imagine a room with a refrigerator which is internally at room
- temperature and which has a tray of tepid water in the freezer. We
- shut the door of the refrigerator and start the compressor by
- plugging it into a battery. Next the room in which the fridge and
- battery are located is insulated and sealed so that it is an
- essentially isolated system. The temperature of the water in the
- freezer will drop and the heat removed from the water will be
- pumped into the room. Soon the water freezes into ice. The water
- molecules in the ice are more highly organized than they were as
- liquid water; because their organization will be greater, the
- entropy of the water is less.
-
- However, as this happens, some of the energy in the battery will
- no longer be available. Therefore, the entropy of the battery will
- increase. Since the room becomes warmer, the molecules of the air
- will crash about more turbulently, in a more disorganized fashion.
- This results in an overall entropy increase in the room. Thus, the
- water* (and air) in the refrigerator will have a decrease of
- entropy while the battery and air in the room will suffer an
- increase of entropy.
-
- According to the 2nd Law, the entropy of the sealed, room -- an
- isolated system -- must increase or remain the same. However, when
- real processes are considered, the entropy will not remain the same
- it will always increase. Hence, the entropy of the battery and air
- of the room will increase more than the entropy of the water will
- decrease.
-
- The 2nd Law allows the entropy of a real, closed subsystem to
- decrease as long as the total entropy of the isolated system
- containing it increases. The phrase "essentially isolated" was used
- because there is no real system which is ideally isolated. However,
- the "essentially isolated" system is one in which any slight
- residual interactions of the system with the outside will not
- significantly affect the numerical value of the entropy compared
- to the system's net change of entropy.
-
- The earth's surface has never been an isolated system because it
- has always received energy from the sun. Therefore, there can be
- local decreases in entropy at the earth's surface while, at the
- same time, the entropy of the sun-earth system essentially an
- isolated system, increases. The evolution of living things is
- simply a local decrease of entropy and is not a violation of the
- 2nd Law.
-
- An important experiment inspired by publications of A. I. Oparin
- in the 20s and 30s was carried out by Stanley Miller in the 50s.
- He produced, from simple precursors in a closed system, complex
- organic molecules required by life forms, rudely violating the
- "creationist's law of entropy."
-
- Into a closed but not isolated system -- a sealed glass bulb
- containing a soup of raw chemicals -- he introduced ultraviolet
- light and high-voltage electricity, conditions that were believed
- to duplicate the early earth's surface. In short order complex
- organic molecules were produced -- a lowering of the closed
- system's entropy. Among these compounds were several amino acids,
- essential ingredients in the chemistry of life.
-
- Already more than six-dozen varieties of organic molecules have
- been detected in comets, meteorites, and both galactic and
- extragalactic dust clouds. These latter are examples of entropy
- decreases on a cosmic scale. (A summary of much of this evidence
- is given in the March 88 issue of "Discover".
-
- The creationists and their fellow ultra-fundamentalists, having a
- corner on the truth, realize that scientific principles can be
- correct only if they are congruent with their version of Revealed
- Truth. Thus, they must alter or deny any principles that conflict
- with that Truth. Galileo fell before the fanatical onslaught of
- their seventeenth-century counterparts. A terrifying intellectual
- chill gripped southern Europe after his trial, and the
- Enlightenment was almost savaged in gestation.
-
- Here, in twentieth-century America, these zealots are succeeding
- in banning many great literary classics from Shakespeare to
- Steinbeck. But, worst of all, is their attempt to force the
- oxymoronic "scientific creationism" into the nation's science
- classrooms and the minds of youth. This is a perversion of the
- content and methods of science, and we must resist.
-
- *Since change of entropy equals the heat transferred to a system
- divided by the temperature of the system, the entropy change of the
- water is negative since heat leaving the water is negative by
- convention. This should prevent arguments that the change of
- entropy of the water should actually be positive because there will
- be less available (heat) energy in the water -- a problem created
- by conflicting applications of the two popular definitions of
- entropy.

- UNDERWATER ARCHAEOLOGY: GOODBYE COLUMBUS
-
- Marco Maniketti, underwater archaeologist, will be the featured
- speaker at the April BAS meeting.
-
- In 1985, underwater archaeologists were searching for the wreckage
- of Columbus's last two ships. The project was offered "help" from
- the Mobius Society, a group capable of "remote sensing". The
- members of this clan alleged that they could use their psychic
- abilities to locate the sunken remains. They were encouraged to
- submit their information, and, in time, they claimed a 75% success
- rate even though the wreckage was never found! Mr. Maniketti
- witnessed the whole experiment and the attempts to justify their
- failures.
-
- Marco will make his presentation complete with photographic slide
- details of this experiment, showing how remote viewing "works", and
- why people continue to believe in it.
-
- Remote viewing, pioneered largely by Bay Area physicists Targ and
- Puthoff, has been something of a mainstay of psi, so Marco's
- observations are an important contribution to skeptical
- understanding.
