I rather think that you overstate your case about the conditions
regarding research into flight in 1900. Almost any biography of the
Wright brothers will leave you hanging on your seat, wondering if
they will really get there first. From the point of view of the
informed observer in 1900-1903, it was not obvious that the Wright
brothers were on the inside track. Langley was working hard to build
a flying machine, and had he been a better engineer, he might have
succeeded. After all, he had the full resources of the Smithsonian
Institution behind him as well as the not inconsiderable prestige of
Alexander Graham Bell. Had not Chanute been killed in a glider
accident, he might have been a contender, or an ally of the Wrights
and helped them to make it even earlier than they did. Had someone
else redone Cayley's wind tunnel experiments before the Wrights
realized that those results were flawed, they might have gotten there
first.
Yes, members of the public certainly saw their aircraft. The public even
wrote numbers of letters to the local Dayton newspapers, and the
newspapers' response was to complain about all of the time that their
people had to waste in opening all these letters from crazy people who
were seeing impossible things. Those newspapers refused to send a
reporter to check out the Wright's claims. After this experience, the
Wrights packed up and moved to Paris.
This isn't too surprising. Although they didn't try to keep their
efforts in Dayton a secret, they didn't make a huge effort to create
a public sensation, either.
And the people who they kept inviting to
visit them were probably the least likely to do so. Few people in the
army at the time could have envisioned any practical use for one of
these "flying machines," and there were very few scientists who had
any particular interest in what they were doing, and if they did,
such as Langley, they were interested in doing their own flying
projects. Why should the give free publicity to the Wrights?
Business
people would not be interested if they couldn't see a potential
profit in it, and the press is notorious for ignoring important
stories until they are forced to by events.
Heavier-than-air flying machines are impossible." - Lord Kelvin,
president, Royal Society, 1895.
"The demonstration that no possible combination of known substances,
known forms of machinery, and known forms of force can be united in a
practicable machine by which men shall fly for long distances through
the air, seems to the writer as complete as it is possible for the
demonstration of any physical fact to be." - astronomer S. Newcomb,
1906
The history of science is replete with silly quotations by experts
and others about various phenomena that the speaker didn't think was
possible or had happened.
Going back further, Jefferson is said to have remarked scornfully
about the reports of "rocks falling from the sky," shortly before
they were finally verified by reports that were considered more
reliable than any previous ones.
I can't remember the quotation but
it had to do with what he would be willing to believe before he would
believe in the rocks from the sky.
And the alternative was something
we still think to be pretty unlikely. But the fact is that, once
reports were received that the relevant people considered reliable,
the phenomenon was quickly accepted and hypotheses developed and
tested to account for it.
And what about cold fusion? Is that dismissed by most scientists out
of pathological disbelief?
I seriously doubt it. The potential for
this technology, should it be true, it simply too great to dismiss it
out of hand, and, if you recall, it wasn't. In fact many people tried
to replicate Pons & Fleishman's experiments.
It was only after it
became clear that they couldn't be reproduced, and P&F became more
and more secretive about their methods, that skepticism overtook
optimism, and the idea was dismissed.
This, moreover, is typical when
some major new claim is made about nature. If the experiments are
easily reproduced, as were P&F's, the initial reports are positive,
but as time goes on the positive reports become fewer and farther
between and negative reports become more common, eventually becoming
nearly universal. Provided the inital reports are a false alarm. If
the phenomenon is real, then positive reports keep coming in, as well
as reports of new related phenomena.
This was the case with high
temperature superconductivity, which has now become mainstream
science, although its original discoverers were reportedly told by
their superiors to stop this line of research because it was proving
fruitless. They continued clandestinely, and the rest is history.
I don't believe that most scientists fall into the category of
"pathologically skeptical," although I hope that they can be counted
as "rationally skeptical."
It is important to remember that when new
and amazing things are reported, that the burden of proof rests on
the reporter and that "extraordinary claims require extraordinary
evidence." It may take a while, as it did with Wegener's hypothesis
of continental drift, but if it is valid, it will eventually be shown
to be true.
There are areas of science that are so well developed that it is not
unreasonable to reject challenges to them out of hand; for example,
the laws of thermodynamics.
During several hundred years of
searching, no violations have been discovered. Similarly, in the case
of the so-called "paranormal phenomena," in a similar time scale no
credible evidence for their existence has been found. It is not
"pathological skepticism" to reject such claims in the absence of
convincing evidence.
Sorry for running on. This is a favorite topic of mine.
