About This Presentation
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. A...

RANKING
Across the entire spectrum of physics,
Einstein liked General Relativity and
Thermodynamics best because they
are both derived from fundamental
considerations of how the universe
works; their completeness; and as
fundamentally emergent properties
of our observations over millennia
“A theoretical physicist who excelled in the art of
‘mind-experiments’ to the point of revolutionising
science, scientific thinking, and methodologies”

Exemplar Subject
The story of Thermodynamics is one scientific investigation and
application at its best. Not only was it conducted over a period
of >200 years, it enjoyed the highest levels of professionalism,
collaboration and technical thoroughness. It also saw new layers
of application, technology, methodology, techniques & practices
as they became available. In turn, these progressively enhanced
measurement and modelling accuracy to broaden our knowledge
at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a
primary tool of exploitation in the advance of applied science/
engineering/technology, spanning micro-tech, to aerospace and
cosmology. I can think of no better story to illustrate the
richness of science methodologies and the value of continuous
collaboration, corroboration and refinement!

•Universe is expanding faster than previously thought
•It is not homogenous but made up of large clusters
•Massive galaxies evolved earlier than predicted
•New and unexpected structures observed
•The ‘Hubble Model’ is now in question!
•New cosmology model may be required

There is considerable debate on our ‘model’ of the universe on almost
every aspect, but as to the total energy stasis: the weight of
opinion seems to be with energy loss as a part of the
expansion et al process. But this is not
certain, and was not an issue in
Boltzmann’s time and
earlier!

VOYAGER II
Living proof that Thermodynamics is alive and
working well on its tour of interstellar space
Launched on Aug 20 1977
Operational for 47 years to date!
Visited Jupiter (79), Saturn(81), Uranus (86), Neptune (89)
Today May 2024: 136.1 AU (20.4 Bn km) out
Reference 0: 136.1 AU (20.4 Bn km) ~0.022 light years
Reference 1: Limit of Milky Way is 6Bn AU (~95k light years)
Reference 2: Proxima Centauri 253kAU, Betelgeuse 30M AU
Reassurance: On the scale of what our species might
aspire to do or achieve, I think we can
safely assume that the theory and
foundation of thermodynamics
is safe and solid for some
considerable distance
into the future!

Universe
A concern/uncertainty on the scale of an
all embracing Thermodynamics model …
Expanding Universe: Sees energy decrease with time as matter and radiation is diluted.
Matter to Energy: Nuclear fusion in stars + accretion of matter into black holes, sees
matter converted into energy through radiation release and generation of high-energy
particles contributing to a gradual reduction in the overall energy content of the universe.
Dark energy: A property of space itself, contributing to the overall energy density.
Particle Physics: Decay of unstable particles and annihilation of particle-antiparticle pairs
etc al, sees energy conversion from one form to another, altering the total energy.
Conservation of Energy: Still applies within the universe with energy mutation from one
form to another (a consequence of the dynamic cosmos) but it cannot be created or
destroyed.

Universe
A ‘minor’ concern/uncertainty in the grand scale
of an all embracing assumption for a universal
Thermodynamics model …
An open system can exchange both energy and matter with its surroundings.
A stove top is a good example as heat and water vapour can be lost to the air.
A closed system, can only exchange energy (no matter) with its surroundings.
An electric motor, mobile, computer are good examples
A key assumption underlying all that follows.
Our universe is a closed system where energy and matter remain constant - nothing
enters and nothing leaves - nothing!
At this time we have working technology outside our solar system,
and indeed, beyond our galaxy, and this supports the closed
model ! Voyager 2 it is still sending images back to Earth….and
this ‘truism’ appears to hold.

A cosmological hypothesis that has yet
to be observed in reality. Today, such a
prospect is way beyond our technology
and engineering abilities to disprove or
prove, but does it matter?
What about
Wormholes?
“For now and way into the future we can
rest assured the assumptions and Laws of
Thermodynamics are secure for the further
use of many generations to come”

issue of where any ‘imbibed’ materials might go
beyond the singularity - and does it change anything?

reality in education, and the professions, sees serious
implications for the way we think, conceptualise, and gain

Mathematician Leonhard Euler and son Albert (1750s) experimented with/characterised waterwheels
Mathematician Jean-Victor Poncelet (1862) proposed inward-flowing radial turbine - modern turbine precursor
Engineer Samuel B. Howd (1838) patented enclosed vertical spindle & curved blades.
Hydraulic Engineer James B. Francis (1892) added guide vanes and shaped blades
Francis turbine still the most widely used for medium-high heads/pressure
Engineer James Thomson added pivoted curved guide vanes to optimise flow
NOTE: Non of these people were ‘single-topic’ (delta function) thinkers! They
had broad/deep educational backgrounds, and an interest in ‘everything’ - most

LAW 2: Full energy and state accounting
Celestial Ratchet - entropy of any isolated system always increases
Entropy can be thought of in terms of order and disorder
All systems tend toward a disordered state
Times Arrow - One way processes
We remember the past and not the future
Drop a cup and it smashes, but the reverse never happens
A battery always discharges it never decides to recharge itself
We live and then die and not the other way round - there are no zombies
The more energy is dispersed - the greater the entropy
Hot coffee in a mug is concentrated - but as the heat dissipates the
heat flow sees entropy fall in the mug and rise in the environment

GENERAL FORM
Derived from the kinetic theory of gases
Historically; Thermodynamics and nearly
all the early thinking emerged from
considerations of a number a number of
industrial problems related to heat
generation, flow and exploitation in the
transformation into motion
Development; It was soon realised and
shown that all the laws could be derived
from the study of molecular movement at
an individual and fundamental level - and
therefore, be based on a statistical model
concerned with the probabilities
associated with movement and location

ENTROPY FormulationS
Many formulation variants - some more convenient or easier to deal with than
others depending on educational background/mode of thinking distribution but
the outcome/form is always the same and so are all the conclusions. There are
no conflicts or exceptions created by the many different methodologies, particular
application, or discipline. This is a level of surety and confidence rarely achieved in
the majority of scientific endeavours!

In many practical cases a system’s thermodynamic micro-states are not equally
probable: eg, high energy states are less probable than low energy at a fixed
temperature
And so the equal probabilities assumption does not always obtain, but a well
established generalisation is given by Gibbs:

in engineering and information science…and there

EXCEPTION ALERT: New Dimensions ??
Our reality of 4 dimensions appears to be a fraction of an 11 dimensional universe.
But all of the above is based on millennia of evidential understanding of our 4D
‘reality’ and the Laws of Physics appear immutable. Though challenged and tested
continually they remain steadfast and the foundation of our understandings.
There is always room for new discoveries, but unless there is another reality of
different and/or more dimensions the Laws of Thermodynamics remains our
most complete model, at the core of our base understandings of the universe in
which we live.

“At the heart of science is an essential balance
between two seemingly contradictory attitudes — an
openness to new ideas, no matter how bizarre or
counterintuitive they may be, and the most ruthless
skeptical scrutiny of all ideas, old and new. This is
how deep truths are winnowed from deep nonsense."
