What is science? (Can There Be a Science of Mind?) (Updated August 2010)Aaron Sloman
This presentation gives an introduction to philosophy of science, though a rather idiosyncratic one, stressing science as the search for powerful new ontologies rather than merely laws. You can't express a law unless you have
an ontology including the items referred to in the law (e.g. pressure, volume, temperature). The talk raises a
number of questions about the aims and methods of science, about the differences between the physical sciences and
the science of information-processing systems (e.g. organisms, minds, computers), whether there is a unique truth
or final answers to be found by science, whether scientists ever prove anything (no -- at most they show that some
theory is better than any currently available rival theory), and why science does not require faith (though
obstinacy can be useful). The slides end with a section on whether a science of mind is possible, answering yes, and explaining how.
The document discusses the history of the author's views on physics. As a high school student, they disliked physics due to not understanding equations. Their view changed after taking undergraduate physics classes, which they found fascinating. During their time at a physics institute, they conducted original research, discovering a new solution to the Yang-Baxter equation through taking limits of an elliptic beta integral. Conducting research was a new experience that required sustained effort over weeks before achieving success, which gave them an ecstatic feeling of discovery.
This chapter introduces the key concepts of physics, including the fundamental aspects of describing the universe, understanding natural laws, and deducing and applying these laws. It discusses the development of scientific knowledge through models, evidence, analysis, and theories tested by experiments. Finally, it outlines several objectives for students to describe physics inquiry and applications across career fields like engineering, medicine, business and other sciences.

This document discusses Kepler's laws of planetary motion and Newton's formulation of universal gravitation. It provides context on Kepler's empirical derivation of his three laws from observations, and how Newton was able to prove Kepler's laws mathematically using his laws of motion and the inverse square law. The document also examines what constitutes a scientific law and how Kepler's laws and Newton's laws can be considered laws of nature given their ability to describe and predict planetary motions through mathematical formulations.
The document provides an overview of the development of physics and chemistry from ancient times through the 18th century. It discusses Aristotle's theories of motion and causation and how teleological reasoning was later rejected. Key figures discussed include Galileo, Copernicus, Kepler, Newton, Boyle, Priestley, Lavoisier, and Dalton. Major topics covered include the discovery of gases like oxygen and hydrogen, developments in astronomy, formulations of gravity, gas laws, and the kinetic theory of gases.
The essential strength of the science of physics lies in the depth of its conceptual schemes, in the relatively few principles that to unify a broad range of knowledge about the physical universe.
One foundation of this knowledge comes from Isaac Newton and those on whom he based his work. These scientists not only solved an important problem in the field of dynamics, they laid the groundwork for the thought processes involved in solving these problems.

The Physical World as a Virtual Reality

Not only is the universe stranger than we imagine, it is stranger than we can imagine
Sir Arthur Eddington
Abstract
This paper explores the idea that the universe is a virtual reality created by information
processing, and relates this strange idea to the findings of modern physics about the physical
world. The virtual reality concept is familiar to us from online worlds, but our world as a virtual
reality is usually a subject for science fiction rather than science. Yet logically the world could be
an information simulation running on a multi-dimensional space-time screen. Indeed, if the
essence of the universe is information, matter, charge, energy and movement could be aspects of
information, and the many conservation laws could be a single law of information conservation.
If the universe were a virtual reality, its creation at the big bang would no longer be paradoxical,
as every virtual system must be booted up. It is suggested that whether the world is an objective
reality or a virtual reality is a matter for science to resolve. Modern information science can
suggest how core physical properties like space, time, light, matter and movement could derive
from information processing. Such an approach could reconcile relativity and quantum theories,
with the former being how information processing creates space-time, and the latter how it
creates energy and matter.
Key words: Digital physics, virtual reality, information theory
Modern online games show that information processing can create virtual “worlds”, with their
own time, space, entities and objects, e.g. “The Sims”. However that our physical world is a
virtual reality (VR) is normally considered a topic of science fiction, religion or philosophy, not a
theory of physics. Yet the reader is asked to keep an open mind, as one should at least consider a
theory before rejecting it. This paper asks if a world that behaves just like the world we live in
could arise from a VR simulation. It first defines what VR theory entails, asks if it is logically
possible, then considers if it explains known facts better than other theories.
Strange Physics
While virtual reality theory seems strange, so do other current theories of physics, e.g. the many-
worlds view of quantum physics proposes that each quantum choice divides the universe into
parallel universes [1], so everything that can happen does in fact happen somewhere, in an
inconceivable “multi-verse’ of parallel universes. This is a minority view but surprisingly
popular. Even relatively main-stream physics theories are quite strange. Guth’s inflationary model
suggests that our universe is just one of many “bubble universes” produced by the big bang [2].

The document summarizes the scientific method process used by two engineers, James Czarnowski and Michael Triantafyllou, to improve ship propulsion systems. (1) The engineers observed that ships use a lot of fuel and penguins are efficient swimmers. (2) They hypothesized that a propulsion system imitating a penguin's wing movements would be more efficient than propellers. (3) To test their hypothesis, they conducted experiments comparing propeller-driven boats to designs with movable panels resembling penguin wings.

We usually credit the beginning of modern science to Galileo, while the work of Newton helped to describe gravity and the causes of planetary motions. Newton formulated some of the fundamental laws of physics and his work not only helped us understand the force of gravity, but also sparked the technological developments of the Industrial Revolution. In the 20th century, Albert Einstein changed our understanding of such basic concepts as space, time, and mass, refining Newton’s laws to make them applicable to the vast regions and exotic objects that we find in a universe much larger and more wondrous than the one that Newton envisioned.
Over time, scientists continued to describe in more and more detail ideas and thoughts about gravitational force. Use information from the textbook and the internet to provide a summary of each development of the understanding of gravitational force.

Summary: Big Bang theory is the most widely accepted cosmological model. It has been widely claimed that it is well supported by evidence. However it is found that it is only a convenient explanation for several observations but the assumptions underlying Big Bang theory are neither supported by independent evidence nor meet the test of plausibility. Big Bang theory and observations explained by it are the only evidence in support of assumptions underlying Big Bang theory. Moreover alternative explanations to the same observations do exist but they have not been duly considered so far.
Author: Dr Mahesh C. Jain is a practicing medical doctor has written the book “Encounter of Science with Philosophy – A synthetic view”. The book begins with first chapter devoted to scientifically valid concept of God and then explains cosmic phenomena right from origin of nature and universe up to origin of life and evolution of man. The book includes several chapters devoted to auxiliary concepts and social sciences as corollaries to the concept of God. Consciousness is one of the aspects of and had to precede origin of universe. This is the only book which deals with origin of nature and universe from null or Zero or nothing.

This document provides an overview of astronomy and the scientific method. It discusses:
1) Astronomy as the study of objects beyond Earth and how they interact, with the goal of organizing our understanding of the universe's history.
2) The scientific method as a process of making observations, developing hypotheses, and testing them through experiments or further observations. Hypotheses must be falsifiable to be scientific.
3) Scientific laws as consistent rules that describe natural phenomena, allowing our understanding to be applied universally throughout the universe. Laws are subject to revision with new evidence.
Respiration and circulation are vital body systems. The respiratory system brings oxygen into the body and removes carbon dioxide through breathing and the circulatory system transports these gases throughout the body using the heart, blood and blood vessels. Together these systems work to provide oxygen and remove wastes to keep cells functioning properly.

We usually credit the beginning of modern science to Galileo, while the work of Newton helped to describe gravity and the causes of planetary motions. Newton formulated some of the fundamental laws of physics and his work not only helped us understand the force of gravity, but also sparked the technological developments of the Industrial Revolution. In the 20th century, Albert Einstein changed our understanding of such basic concepts as space, time, and mass, refining Newton’s laws to make them applicable to the vast regions and exotic objects that we find in a universe much larger and more wondrous than the one that Newton envisioned.
Over time, scientists continued to describe in more and more detail ideas and thoughts about gravitational force. Use information from the textbook and the internet to provide a summary of each development of the understanding of gravitational force.

Summary: Big Bang theory is the most widely accepted cosmological model. It has been widely claimed that it is well supported by evidence. However it is found that it is only a convenient explanation for several observations but the assumptions underlying Big Bang theory are neither supported by independent evidence nor meet the test of plausibility. Big Bang theory and observations explained by it are the only evidence in support of assumptions underlying Big Bang theory. Moreover alternative explanations to the same observations do exist but they have not been duly considered so far.
Author: Dr Mahesh C. Jain is a practicing medical doctor has written the book “Encounter of Science with Philosophy – A synthetic view”. The book begins with first chapter devoted to scientifically valid concept of God and then explains cosmic phenomena right from origin of nature and universe up to origin of life and evolution of man. The book includes several chapters devoted to auxiliary concepts and social sciences as corollaries to the concept of God. Consciousness is one of the aspects of and had to precede origin of universe. This is the only book which deals with origin of nature and universe from null or Zero or nothing.

It also explains how resistance and resistivity change with temperature and the formulas for calculating equivalent resistance when resistors are combined in series or parallel.
This document summarizes a physics lecture on rotational motion. It discusses rotational kinetic energy, moment of inertia, torque, and Newton's second law for rotational motion. Key concepts covered include:
- Rotational kinetic energy depends on the moment of inertia and angular speed.
- Moment of inertia depends on the mass and how it is distributed relative to the axis of rotation.
- Torque is a measure of the ability of a force to cause rotational motion and depends on the magnitude and direction of the applied force relative to the axis of rotation.
- Newton's second law for rotational motion states that torque is equal to the moment of inertia times angular acceleration.
The document discusses transistors and transistor amplifiers. It describes the basics of NPN and PNP transistors, including their symbols and how current flows. It then explains common base and common emitter configurations, showing the transistor characteristics and how they function as amplifiers in each configuration. The key gains of current, voltage, and power are also defined for common base amplifiers.
Respiration is the process of oxidizing organic compounds to release energy. In plants, gas exchange occurs through stomata, while in animals it occurs through a specialized respiratory system. The lungs are the main organs of respiration in humans. They are located in the thoracic cavity and have an elastic structure with alveoli that maximize surface area for gas exchange. Oxygen and carbon dioxide diffuse between the alveoli and blood based on partial pressure gradients, with oxygen moving into the blood and carbon dioxide moving out.

This slide deck provides the outline for the semester-long course. Each week’s lecture topics, with key
points to be covered, are highlighted in two slides, which also list writing prompts, problem-solving
exercises, and labs. We have envisioned this course to assess students with a large set of low-stakes,
real-time assignments. Perhaps most usefully, we have curated a list of high-quality online video
resources that students (and instructors) should use to help them learn (and teach) physics ideas and
concepts using demonstrations, animations, and humor. Many of those videos are parts of larger series
and programs, created by some of the most skilled and popular online presenters in the world; that means
some of their content is commercially sponsored, but all the content is free to users like you and me.
We expect the suite of materials for this Physics For Everyone OER to grow over time as the course is
taught and its history lengthens. We look forward to sharing all of it with you, and thank you in advance for
helping us increase and improve it all in the weeks and months to come.

5. 1.1 What’s physics?
* Physics is the scientific study of the structure,
content, and activity in and of the universe
* Physics describes how space, time, matter,
and energy interact to produce all that exists
* Physics is the fundamental science – it's at
the core of astronomy, biology, chemistry,
engineering, geology, and medicine
* Physics is the bedrock of our technological
modern society – just about everything in our
daily lives has come about because of physics
Keywords: science, non-science, pseudoscience,
fact, law, hypothesis, theory, Aristotle, Alhazen,
Bacon

scientific law and a scientific theory?
6. 1.2 What's physics – and why do we care?
* If we want to live in comfort, build wealth, cure
disease, and improve our quality of life, we must
understand and use physics to do it
* If we want to live in safety, maintain good
health, protect our homes, and make the world a
better place for ourselves and those we care
about, we must know enough about physics to
harness its power in our best interests
* Don't buy into the myth that physics is too
“hard” or “useless” or “scary” - physics is
fascinating, far-reaching, and fun!
* Reading 1: College Physics, Ch.1.1
(Physics: An Introduction)
* Writing 1: Read Karl Popper’s1963 essay
Science as Falsification, widely available online
(e.g., staff.washington.edu/lynnhank/Popper-1.pdf).
Write down three sentences that encapsulate
the “big ideas” of this essay to you. Then read
two other Internet essays written about this
essay. Give their authors and URLs, whether
they agreed or disagreed with you, and why.
* PS 1: Do astrologers predict the future better
than you do? Let’s find out!
7. 2.1 Motion: inertia, momentum, and force
* Galileo Galilei, considered by many to be
history’s first “physicist,” articulated inertia – that
objects in motion tend to stay in motion. His life
was marked by conflict with established norms,
always pushing against non-scientific authority.
* Isaac Newton inextricably tied science with
math and quantitative reasoning, explaining that
objects move following predictable equations. His
efforts helped make physics the basis of society,
bringing Galileo’s efforts to meaningful fruition.
* Rotation, like motion in a straight line, is also
fundamental to how objects move.
Keywords: Galileo, experiment, Newton, action,
reaction, angular momentum, torque
* Reading 2: College Physics, Ch.4.1 – 4.4
(Newton’s Laws of Motion)
* Writing 2: Watch several scenes of The Life
of Galileo as performed in 2009 by the Asolo
Repertory Theatre. Choose one scene that
connects with you; explain how and why –
characters, dialogue, themes, science are just
some of the ways it could do so.
* PS 2: Throw a ball. How fast does it fall?
8. 2.2 Motion: inertia, momentum, and force
* Law of Inertia: Objects that are in motion tend
to stay in motion at constant speed in a straight
line unless acted upon by an outside force.
(Conservation of momentum)
* Law of Force: The force exerted on an object is
equal to the object’s mass multiplied by the
amount the object is accelerated.
* Law of Reaction: For every action there is an
equal and opposite reaction.
* For rotation, “momentum” is replaced by
“angular momentum” and “force” is replaced by
“torque.”
* Mini-lab 2: How Do They Drop? If you push
pennies off a table, do they fall faster than
dimes? Or if they’re pushed harder?

9. 3.1 Motion: gravity, work, and energy
* Johannes Kepler used decades of data to
deduce three laws of orbital motion.
* Isaac Newton extended his laws of motion to
cosmic objects, and was able to explain the laws
of orbital motion by positing the existence of a
force called gravity.
* Gravity, reasoned Newton, acts between two
objects at a distance, is directly proportional to
the mass of the objects, and follows an inverse
square law with respect to distance. He was
mostly correct – and we still use his mathematical
formulations today in almost all cases.
Keywords: Kepler, orbit, Halley, Bernoulli,
rocket equation, weightlessness, space travel
and exploration
* Reading 3: One Universe, “Motion”
* Writing 3: What would it take for humans to
set foot on the Moon again? Should we try?
* PS 3: Will that asteroid hit Earth? If it does,
how much will it hurt?
* Mini-lab 3: Follow the bouncing ball – can
you send an object into a suborbital trajectory?
10. 3.2 Motion: gravity, work, and energy
* Edmund Halley helped complete the elevation
of Newton’s laws to a confirmed scientific theory.
Halley’s Comet – and the solar system today
* Flight: Bernoulli, lift, the Wright brothers
* Rockets: Tsiolkovsky, Esnault-Pelterie, Goddard
and the rocket equation

11. 4.1 Energy: potential, kinetic, and heat
* The conservation of energy may be the most
fundamental property of the physical universe –
not to be confused, though, with “conserving”
energy in our daily lives, which also matters!
* James Joule devoted his life to figuring out the
relationship between work and energy. Nicolas
Léonard Sadi Carnot gave further clarity to how
heat and energy are related, and how heat can
be used to do work.
* Entropy – in disorder, energy is stored. The
laws of thermodynamics explain it all: you can’t
win, you can’t break even, and you can’t get out
of the game.
Keywords: Joule, heat engine, Carnot,
conservation laws, heat capacity, greenhouse
effect
* Reading 4: One Universe, “Energy”
* Writing 4: What sorts of fuels would you like
to use to power our future civilization?
* PS 4: How much heat is in a hurricane?
How much is that compared to an atomic bomb
– or the heat needed to cause a one-degree
increase in global temperature?
12. 4.2 Energy: potential, kinetic, and heat
* Matter retains heat and moves heat around –
heat capacity, conduction, convection, radiation
* Machines help get work done; engines are real-
world work-energy conversion devices with some
inefficiency and a major waste product: heat
* When heat is retained in complex systems,
what can result? For Earth, it can mean floods or
droughts, hurricanes or blizzards, and lots of fire

13. 5.1 Matter: atomic and subatomic
* The smallest piece of any matter that retains its
identity – what is it? From the ancient Greeks to
today, it’s been called an atom – what are they
made of, though?
* The “Bohr atom” with electrons orbiting a
nucleus, first presented by Danish physicist Niels
Bohr (also New Zealand-born Ernest Rutherford)
is the basic model taught in schools today
* Rutherford’s gold foil experiment confirmed that
nuclei were tiny compared to the atom as a whole
(exceptions: electron degenerate and neutron
degenerate matter – white dwarfs and neutron
stars – not found anywhere on Earth)

15. 6.1 Matter: solids and fluids
* What makes solids solid? Crystals sound
solid, for example – but you’ve heard of liquid
crystal displays (LCDs), right?
* Solidity doesn’t mean density – the difference
between solid and fluid is not how far apart the
molecules are.
* Solids have elasticity, and physical systems
with many connected solid pieces move
differently from single pieces of material. Fluids
have viscosity (water vs. molasses) that
dissipates energy, often as heat
Keywords: crystal, glass, liquid, gas, pressure,
temperature, ideal gas law, elasticity, viscosity
* Reading 6: One Universe, “Matter”
* Writing 6: The search for life on Mars – why
solid, liquid, and gas all matter
* PS 6: How hot is your pressure cooker?
* Mini-Lab 6: What’s the best way to warm our
fingers, rubbing or blowing or something else?
16. 6.2 Matter: solids and fluids
* Fluids can be incompressible (typically known
as liquid) or compressible (gas). Fluid mechanics
and hydrodynamics are, generally speaking, the
physics of huge numbers of tiny particles
affecting their surroundings as an ensemble.
* The ideal gas law (PV = NRT or P = nkT)
explains the relation between temperature and
pressure – for air, it’s “close” to exactly accurate
* What’s not exactly accurate about it?
Collisions, mixtures, solutions, precipitates, and
more – and that’s a good thing.

17. 7.1 Matter: condensed, in phases
* Solid, liquid, and gas are three states of matter
with which we are familiar. When a substance
(like H2O) changes states (like from ice to water
to vapor) temperature and pressure are involved.
* Phase changes are not always visible to the
eye. Deep and significant physical changes can
happen even if the state of a substance stays the
same.
* Entropy change is key to phase change. A
phase diagram describes the boundaries in
temperature and pressure that require adding or
removing heat (of vaporization or solidification,
for example) to cross.
Keywords: phase diagram, absolute zero,
superconductivity, Bose-Einstein condensate
* Reading 7: College Physics, Ch. 14.1 – 14.4
(Heat and heat transfer)
* Writing 7: What does it mean to you in your
life when something is hot or cold? How about
superhot or supercold?
* PS 7: How powerful is a superconducting
magnet?
18. 7.2 Matter: condensed, in phases
* Bose-Einstein condensate is a phase of matter
very close to absolute zero in temperature.
* Superconductivity is a fascinating phase - see
nationalmaglab.org/education/magnet-academy/learn-the-
basics/stories/superconductivity-101
(National High Magnetic Field Laboratory)

19. 8.1 Waves: sound, light, and radiation
* How can energy be transferred from place to
place without actual contact? Waves.
* Longitudinal waves: acoustic waves traveling
through a medium, for example. Decibels are a
way to measure the power carried in a sound
wave.
* Transverse waves: ripples in a pond, for
example, where the water moves vertically (up
and down) while the energy moves horizontally
(outward).

20. 8.2 Waves: sound, light, and radiation
* Waves in matter can rip apart solid ground,
roads, bridges, and more.
* Superposition of waves – music and colors
* Electromagnetic radiation is light – gamma
rays, X-rays, ultraviolet, visible, infrared,
microwave, radio waves

21. 9.1 Electromagnetism
* How powerful is electromagnetism? Think
about a balloon defying Earth’s gravity just with a
little static electricity on it.
* Coulombs measure the amount of charge.
Electric force has the same inverse square law
as gravity – so it can extend far into space.
* Ohm’s Law (V = IR) and the electric power
formula (P = IV) describes how electricity works –
and how electricity drives modern civilization
Keywords: Coulomb, Ohm, Ampere, Watt,
Faraday, dynamo, alternating current, Tesla,
transformer, power grid

* Electric vehicles – the past, present, and future
(did you know that the first electric car was built
before the first gasoline-powered car?) of any car
is about function, convenience, and cost. What
will that mean for us as technology advances?
* Electromagnetism is one of four fundamental
forces in the universe, along with gravity and the
two nuclear forces. This matters at the most
basic level of physics as well as in everyday life.

23. 10.1 Quantum Mechanics
* Thermal radiation (called blackbody radiation)
experiments late in the 1800s led Max Planck to
deduce light quanta.
* The photoelectric effect led Albert Einstein to
deduce the same thing from another direction.
* The famous Solvay conference photo is a
snapshot of the history of “modern physics.”
* A few decades later – including Curie with
radioactivity, de Broglie with wave-particle duality,
Pauli with matrix mechanics, Schrodinger with a
wave equation, and Heisenberg with uncertainty
– quantum mechanics was established.
Keywords: Planck, quantization, deBroglie,
uncertainty, Schrodinger, energy level,

25. 11.1 Nuclear fission and fusion
* The first atomic bombs used nuclear fission.
So does every nuclear power plant operating in
the world – they provide about one-fifth of the
world’s (including the USA’s) electric power.
* Human-produced nuclear fission comes from
slowing down neutrons. Fuel for nuclear fission
must either be enriched (U-235) or manufactured
(Pu-239) and how to do those things – and how
to assemble them into bombs – is well
understood. What does that mean when it
comes to the proliferation of nuclear weapons?
* Nuclear fusion of hydrogen into helium powers
the Sun, and will do so for billions more years.
Keywords: E = mc2, Fermi, Heisenberg, atomic
bomb, Oppenheimer, hydrogen bomb, nuclear
power, Pu-238

* nobelprize.org/prizes/themes/how-the-sun-
shines-2/ (John Bahcall explaining nuclear fusion

* Fusion bombs are also well understood, albeit
much harder to construct and test – they also
usually need a fission bomb to start the process
* There are no controlled fusion reactors yet,
after half a century of trying – are they still worth
the effort to design and build them?
* Nuclear fusion in the universe – called
nucleosynthesis – is the process that built the
elements that in turn have built us all!

27. 12.1 Relativity, space, and time
* In 1905, Albert Einstein explained the apparent
constant measurement of the speed of a light
beam by every observer. The special theory of
relativity was confirmed decades later. (How?)
* The general theory of relatively was developed
by Einstein about a decade later. Then: Arthur
Eddington, the first world war, the influenza
pandemic and the total solar eclipse confirmation.
Decades later: gravitational lensing.
* How do you use general relativity every day?
Mapping and location services via GPS.

29. 13.1 Cosmology and the Universe
* Starting with Einstein’s general theory of
relativity, evidence of the motion (expansion of
space), matter (nucleosynthesis), and energy
(cosmic background radiation) confirms that the
universe started with a Big Bang 13.8 billion
years ago.
* Radiometric dating, meteorite and Moon rock
data, and astronomical observations confirm that
the solar system was created 4.6 billion years
ago, and Earth and the Moon soon thereafter.
* Inflationary universe – did solving the horizon
and flatness problems create an eternally

30. 13.2 Cosmology and the Universe
* Dark matter: more than 80% of the material in
the universe is totally unknown to science. How
do we even know it’s there? Only by its gravity.
* Dark energy: more than two-thirds of all the
energy in the universe is equally unknown to
science. How do we even know it’s there? The
acceleration of common expansion.
* Extraterrestrial life: we’re looking for it. What
have we found so far? Warmth, water, and
SPONCH – but nothing alive. Yet.
