In a world that appears riven by social media, ill-informed opinion, rumour, and conspiracy theories in preference to facts and established truths, it can be alarming to see scientists, doctors, and engineers challenged by vacuous statements that often hold sway over the hard-won truths of science. Moreover, large numbers of people do not understand the ‘scientific method’ and what makes it so powerful.
Paradoxically, those challenging science and scientists based on their belief systems do so using technologies that can only be furnished by scientific methodologies. For sure; no religion, belief system, great political mind, anarchist, professional protester, or social commentator will produce a TV set, mobile phone, laptop, tablet, supercomputer, MRI Scanner, AI system, or vaccine! But they will criticise, challenge, and be abusive based on their ignorance and inability.
So, this is the world that now influences the minds of young aspiring students, and this presentation is designed to go beyond the simple exposition and statement of the scientific principles and method, to provide an ancient, modern, and forward-looking perspective. It also includes a complex ‘worked example’ to highlight the rigour that must be applied to establish any truth!

A recording and sharing revolution
Johannus Guttenberg 1440
William Caxton 1450
Books remained expensive &
hard to sell at first but soon
went from the limited reach
of the church & royalty down
to the rich of society
A transition from Vellum to
Parchment to Paper reduced
costs as did other advances
The biggest initial impact was
a precursor to newspapers -
news sheets: London had >60
All this saw the rapid spread
o f d i s c o v e r i e s , i n v e n t i o n s ,
ideas and new facts
This grew to become a primary

Are we alone & special in the cosmos ?
The scientific method applied
t o o n e o f t h e b i g g e s t
questions for humanity
We start by reversing the question as a workable hypothesis
open to many forms of investigation.
Hypothesis: There are thousands of inhabited worlds!
Observation 1: All the planets and every life form are made from the
same stardust - they share the same chemistry and
molecular structures at a fundamental level
Observation 2: Not all life forms require light & oxygen; but carbon, in
contrast, may be an essential - but it is also available
throughout the cosmos as a highly stable molecule
Proof: This is a complex and challenging problem requiring more
than one method by more than one team
38. D r a k e s E q u at i o n

40. Scanning the sky
Search for ExtraTerrestrial Intelligence
Searching for intelligible radio
s i g n a l s f r o m d i s t a n t s o l a r
system is a big challenge
The latest technical advance is the Allen [Paul Allen Founder of
Microsoft] Array - the
fi
rst radio telescope designed exclusively for
SETI searches - scans 1 - 15GHz from Hat Creek-Cascades 450km
North of San Francisco. A large number of relatively small dishes
extending over 1 km to provide a high-quality beam shape to minimise
unwanted terrestrial noise/interference/terrestrial signals/spoof events
.
The search software [SonATA -SETI] is implemented with enterprise
servers donated by Dell and Intel.
The SETI Institute is a not-for-pro
fi
t research organisation (incorporated 1984) for the discovery/sharing knowledge as
scienti
fi
c ambassadors to the public, the press, and the government in the "search for extraterrestrial intelligence".
Over a 36 year period there have been many false alarms but no conclusive results so far. Drakes equation indicates
that civilisations are very rare events scattered over space and time - and the heavens are vast, signals are weak - henc
e
automation is vital! 2020 represents a new era in this search effort with many new technologies and techniques…
Proof: If and when intelligible signals are detected it will be ‘interesting'-but not proof
until corroborated by many others and a communication channel is established!
41. Spectral Scanning
Search for chemical signs of life/intelligence
A planet’s atmosphere flags
the activities on the surface
/biological/life possibilities
Proof: If and when a promising spectral are detected it can tell us if life might be
sustained, and may be present, and if it is highly intelligent we might detect the
pollutants - it creates - BUT this is not proof ! It is but an indicator suggesting it as a
target identified by SETI and a good reason for fly-by and/or some form of visitation.
42. Sending invitations
Active SETI - multimode connection attempts
Who, what, where requires
s o m e R S V P m e s s a g e o r
physical visitation !
Active SETI Russia et al send radio signals/
messages to intelligent extraterrestrial lif
e
Passive SETI ALL broadcast radio/TV +
satellite signals eta + random space junk
NASAVoyager and the Pioneer plaque
represents a physical invitation to connect
Proof: A visitation would be the ultimate proof !
