This document is the preface to a book titled "Motion Mountain - The Adventure of Physics" which is available free online. The preface outlines the author's goals for the book, which are to present the basics of physics in a way that is simple, up-to-date, and vivid. It aims to foster readers' innate curiosity about how the world works by guiding them on an exploration of physics from atoms to stars without limitations. Key concepts are prioritized over complex mathematics. The book also includes the most recent developments in fields like quantum gravity and string theory. Provocative surprises on each page aim to startle readers into thinking more deeply.
1. The document discusses light and its mysterious nature, noting that light has no mass, charge, or time and always travels at the same speed.
2. It describes the principle of least action, where light always takes the path that arrives at its destination in the shortest time. Some scientists saw this as evidence of a "higher reason" or purpose governing nature.
3. The author argues that purpose is found in the whole or quanta of action, not in its individual parts of mass, length, and time. Planck's discovery that action comes in discrete quanta supports the idea of light as a first cause or purpose in the universe.
- The document discusses quantum physics and wave-particle duality. It explains that quantum physics views matter and light as exhibiting both wave and particle properties, unlike classical physics. It describes how Schrodinger and Heisenberg developed complementary theories and interpretations of quantum mechanics. The document also summarizes applications of quantum theory including lasers, transistors, and medical imaging. It notes that wave-particle duality remains an ongoing mystery in physics.

The standard model of particle physics attempts to describe the fundamental interactions of nature. It classifies all known elementary particles and their interactions via gauge bosons that mediate four fundamental forces. While successful, it is limited and does not account for gravity, dark matter, neutrino masses, inflation, or the asymmetry of matter and antimatter in the universe. Many theories beyond the standard model have been proposed to address its limitations, such as supersymmetry, grand unification, string theory, and others.
The document discusses the three main types of radioactive decay - alpha, beta, and gamma decay. It describes the particles emitted in each type of decay and how they affect the atom. It provides examples of specific radioactive isotopes, their decay processes, and half-lives. It also outlines some medical, industrial, and research applications that make use of different radioactive emitters.
The document discusses various types of nuclear decay:
- Alpha decay involves emitting an alpha particle (helium nucleus), decreasing the atomic number by 2 and mass number by 4.
- Beta decay involves changing a neutron to a proton and emitting an electron, increasing the atomic number by 1 while keeping the same mass number.
- Electron capture involves capturing an electron by a proton to form a neutron, decreasing the atomic number by 1 while keeping the same mass number.
- Positron emission involves changing a proton to a neutron and emitting a positron, decreasing the atomic number by 1 while keeping the same mass number.
- Gamma decay involves emitting high energy gamma rays without changing mass or atomic number.

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].

1) Stephen Hawking summarized his 1980 lecture where he discussed the progress made in theoretical physics over the previous century and questioned if a complete unified theory could be found by the end of the 20th century.
2) In the 1960s, four fundamental forces were known - gravity, electromagnetism, and the strong and weak nuclear forces. Developments in the 1960s and 1970s unified electromagnetism and the weak force, though gravity remained separate.
3) Hawking proposes that like maps of the Earth's curved surface, there may be multiple overlapping theories needed to describe physics in all situations, rather than one single unified theory, though progress continues to be made theoretically through proposals
An approach to understanding psychotronicsClifford Stone
This document proposes a new approach to understanding psychotronics by advancing a "fourth law of logic, the age-old identity of opposites." It presents a model incorporating this fourth law of logic along with Everett's many-worlds interpretation of quantum mechanics. This provides a framework to relate both physics and metaphysics through a cluster of orthogonal spatial frames sharing a single time axis. The model can explain phenomena such as life, death, psi abilities, consciousness, UFOs, and allows materialization of thought forms called "tulpas." It is suggested that some UFO phenomena may be explained as tulpas tuned in from human hyperspatial mindworlds.
This document provides information about physics and notable physicists. It discusses the definition and branches of science and physics. The two main branches of physics are described as classical physics, including mechanics, thermodynamics, electromagnetism, acoustics, optics, electricity, electrostatics, and hydrodynamics. Modern physics is also outlined along with its branches like atomic physics, nuclear physics, quantum physics, solid state physics, and plasma physics. The contributions of notable physicists like Ibn al-Haitham, al-Beruni, Muhammad ibn Musa al-Khwarizmi, and Abdus Salam are highlighted in brief.
String theory proposes that fundamental particles are not point-like but are tiny vibrating strings. It aims to unify quantum mechanics and general relativity by incorporating gravity into a theory of everything at very small scales. String theory predicts that spacetime has 10 dimensions rather than the observed 4 dimensions, with the extra 6 dimensions being curled up too small to detect directly. While strings have never been observed, string theory remains a promising area of research as the only known way to reconcile quantum mechanics and general relativity.
The document discusses the current understanding of what the universe is made of according to the Standard Model of particle physics. It explains that all matter is made up of fundamental particles like quarks and electrons, which in turn are made up of even smaller particles. The document then introduces string theory as a promising candidate for a unified theory that could provide a quantum description of gravity and a "Theory of Everything". String theory proposes that all fundamental particles are actually different vibrational states of tiny loops of string. While string theory derives the Standard Model, there is currently no direct experimental evidence to confirm it is the correct description of nature.

19. First Part
Fall, Flow and Heat
In our quest to learn how things move,
the experience of hiking and other motion
leads us to introduce the concepts of
velocity, time, length, mass and temperature,
and to use them to measure change.
We discover how to float in free space,
why we have legs instead of wheels,
why disorder can never be eliminated,
and why one of the most difficult open issues
in science is the flow of water through a tube.
