QUELQUES RÉFLEXIONS SUR LE CAS OVNI D’UBATUBA EN 1957
SOME THOUGHTS ON THE UBATUBA 1957 UFO CASE
by Jean Bastide
To simplify the matter, a simple exercise in order to understand the percentages of the three earthly Magnesium isotopes:
Magnesium 24 has a percent abundance of
78.99%, Magnesium 25 has 10%. What is the percent abundance of Magnesium
26 ? Assuming we have no other isotopes, the total must be 100%, and we have: %
of Mg24 + % of Mg25 + % of Mg26 = 100. Therefore, we obtain a percent abundance
of Mg 26 = 100 – (78,99 +10)= 11,01% .
In the Ubatuba sample, the result obtained shows a percent
abundance of Mg 26 equal to 14,3 % ( it
appears that –as it was not quite clear and even rather unclear in the article,
the left page giving the value of 14.3- that concerning the Ubatuba sample, it
turns out that the sample’s percent abundance was effectively of the exact
value –see right page-of (0.4085x100 /
2.842)= 14.37368 ) plus or minus 0,7%, value which is statistically significant
and indicative of the existence of a sample notably different from the earthly
one. Strangely enough, neither Dr Craig nor the Colorado project did take this
into account, writing “it should be
noted that the statistical counting error (0,7%) does not include other
analytical errors such as relative counting geometry or neutron thermalization
due to the relative sample sizes. It is felt
therefore that the abundance of the Mg26 in sample 4527 is in reasonable
agreement with the Mg26 abundances shown in the literature”.
Some biased judgment thanks to the “other analytical
errors”(sic)? Why? Asking the question is giving the answer, as recognizing the
true nature of Ubatuba sample would have been an implicit recognition, an
implied acceptance of the strangeness of
this sample, of its unearthly origin to say it bluntly. Note the fast neutron
thermalization implies a slowing down of the neutrons becoming slow
neutrons when the sample size is big
enough, according to the fact that the neutron energy distribution is a
Maxwellian distribution (Maxwell-Boltzmann molecular speed distribution ) like a thermal motion.
