Unit 7 the solar system and beyond-the physics of the universeRicca Ramos
This document provides an overview of physics concepts related to the solar system and universe, including:
- Albert Einstein's theory of relativity from 1905, which proposed that the speed of light is a universal constant and that mass and energy are equivalent.
- Einstein later developed the general theory of relativity in 1907, proposing a new model of gravity as a consequence of objects warping the dimension of spacetime.
- If an object becomes massive enough, it can warp spacetime such that it collapses in on itself to form a black hole.
- The special theory of relativity also predicts length contraction and time dilation for objects moving at relativistic speeds. It established that the speed of light is the ultimate speed limit in
At the subatomic scale, quantum mechanics describes reality in terms of probabilities and measurements that alter the object being measured. Any measurement of a quantum object's position or velocity introduces uncertainty and changes the system's state. The double-slit experiment demonstrates that particles like photons exhibit wave-like behavior such as interference and diffraction.
Schrodinger’s cat describes a paradox in which a cat is located in a sealed black box with a poison sealed capsule inside it. Radioactive source decays and emits radiation, which activates a Geiger counter, The Geiger counter generates a signal to release poison from the capsule and kill the cat. Since the decay of a radioactive source is a random sub atomic event, based on quantum mechanics we can only derive a probability-based assumption on the exact time that the decay of the radioactive atom will occur. The Copenhagen interpretation says that until an observer opens the box, the entire system is in superposition and the cat is both dead and alive. In this paper, I will show that we can extrapolate this superposition paradox also to the time domain and the entropy level of the system.
Introduction – Schrodinger’s cat in the time domain
Let us reconstruct the same thought experiment (figure 1) where a newly born kitten is located in a rocket, orbiting far away from the black hole gravitational influence (orbit A). As the radioactive atom (which is located in the sealed rocket) decays randomly, it radiates, and the Geiger counter detects the radiation and generates an electric signal that activates the rocket engine, which sends the rocket with the cat inside it to circle near the black hole’s event horizon (orbit B). Assuming that near the event horizon time nearly stops due to the strong gravitational time dilation, the age of the cat (or the entropy of the system), becomes a function of a random quantum effect due to the radioactive atom decay.
Summary
There seems to be a dependency between the cat’s age (the entire systems entropy) and the quantum mechanical random effect of the radioactive atom decay.
If the entire macro system (rocket, orbit A, orbit B and the cat ) are in a sealed unmeasurable region ,based on the Copenhagen interpretation , until the observation (the collapse of the Schrodinger’s wave equation) ,the cat age is a superposition of all the possible ages from a newly born kitten to an old or even deceased cat. The location of the rocket is a superposition of orbit A, orbit B and the space between them. This Copenhagen interpretation leads to a disturbing conclusion, which requires that the macro system, Schrodinger wave function, will collapse when measured, in both the space and the time domain. The second law in thermo- dynamics requires that the system entropy will increase in time. In our thought experiment, the entropy level of the entire macro system is dependent only on a single radioactive atom that radiates spontaneously totally disregarding the second law of thermo-dynamics.

A introduction paper to some quantum concepts that steer us to the future of bio-functions, some quantum mathematical computations to consider. written August 2012, more to come...
1) Entropy is a property of a system that quantifies how energy is dispersed within the system, with higher entropy corresponding to a more disordered, dispersed state.
2) The concept of entropy can be explained using statistical mechanics principles of macrostates, microstates, and their multiplicities. More probable macrostates have higher multiplicities.
3) For large physical systems like a cubic centimeter of air, the most probable macrostate approximates the total multiplicity, allowing entropy to be defined as the natural log of the total multiplicity multiplied by the Boltzmann constant. Higher total multiplicity thus corresponds to higher entropy and more disorder.
- Moore's law, which states that computer processing power doubles every 18 months, will slow down in the next 10-20 years as transistors become too small to miniaturize further due to physical limitations. This will usher in a post-silicon era using molecular-scale quantum computers.
- Advances in brain scanning technology like fMRI will allow decoding people's thoughts from brain activity patterns and could enable controlling external devices with the mind. Developing room-temperature superconductors may enable moving objects with the mind via electromagnetic fields.
- Reaching artificial general intelligence will be extremely challenging and requires either perfectly programming intelligence or replicating the brain's learning abilities at the neural level through massive computer simulations or electron microscopy
Quantum entanglement occurs when particles interact and their quantum states cannot be described independently, even when separated by large distances. Schrodinger's cat experiment shows that quantum systems exist in superpositions of states until observed, demonstrating wavefunction collapse is not driven just by consciousness. Quantum computing uses quantum mechanics to solve complex problems, representing information using quantum bits that can be placed in superpositions and entangled states leveraged by algorithms.

1) The talk discusses the origin of structure in the universe, from the small density fluctuations after the Big Bang to the galaxies, stars and planets we see today.
2) It explains how quantum fluctuations during an early period of exponential expansion called inflation were stretched to cosmological scales by inflation, seeding these initial density fluctuations.
3) The talk outlines how measurements of the cosmic microwave background have revealed correlations in the fluctuations that can only be explained by a period of inflation in the early universe that was faster than the speed of light.
The document discusses superconductors and their potential impacts on society. It describes how superconductors could revolutionize electronics and energy systems by allowing electricity to flow with no resistance. Superconductors have the potential to advance fields like medicine, transportation, and energy. For example, superconductors are already used in MRI machines and could enable new transportation technologies like maglev trains. However, more research is needed to discover superconductors that work at higher temperatures, like room temperature, which could vastly improve their applications. The document argues that governments and private organizations should increase funding for superconductor research that could solve energy and sustainability issues.

It was one of the costliest natural disasters in US history.
Molecular dynamics (MD) is a computer simulation technique that uses Newton's laws of motion to model molecular systems. MD allows studying kinetics and thermodynamic properties by simulating molecular motions over time. The key components of an MD simulation include force fields, integration algorithms, boundary conditions like periodic boundary conditions, and ensembles like NVE, NVT, NPT. Limitations include the approximations in force fields and sampling limitations. Enhanced sampling techniques help address some limitations. MD has many applications and continues to provide insights into molecular behavior.
1. The document discusses the imbalance between matter and antimatter in the universe. It proposes that matter is more abundant than antimatter because matter produces antimatter, similar to how bank deposits fund advances.
2. It presents a model treating the universe like a bank's general ledger, with the creation and destruction of particles analogous to financial transactions. This framework aims to explain the conservation of energy despite particles appearing and disappearing.
3. Sophisticated particle experiments study subtle differences between how matter and antimatter decay, which provides evidence these are not perfect mirror images and could explain the matter/antimatter imbalance in the early universe.
The book is designed for a one-semester graduate course in quantum mechanics for electrical engineers. It can also be used for teaching quantum mechanics to graduate students in materials science and engineering departments as well as to applied physicists. The selection of topics in the book is based on their relevance to engineering applications. The book provides the theoretical foundation for graduate courses in quantum optics and lasers, semiconductor electronics, applied superconductivity and quantum computing. It covers (along with traditional subjects) the following topics: resonant and Josephson tunneling; Landau levels and their relation to the integer quantum Hall effect; effective mass Schrodinger equation and semi-classical transport; quantum transitions in two-level systems; Berry phase and Berry curvature; density matrix and optical Bloch equation for two-level systems; Wigner function and quantum transport; exchange interaction and spintronic.
This document discusses zero point energy and its relationship to quantum physics, spirituality, and the manifestation of matter through vibrational frequencies. It suggests that zero point energy is the lowest possible energy state of a quantum system, and remains even at absolute zero temperature. Meditation is presented as a way to access this energy and direct it with intention. Sacred geometry patterns in nature are explained as resulting from the cymatic waveforms created by vibrational frequencies organizing tetrahedron molecules.
This document discusses a formula that governs the particle interchange process in our solar system. The formula is currently out of balance due to two main factors: electricity and radioactive particle production. Evidence of this imbalance includes worsening ozone holes, increasing storms, earthquakes and volcanic eruptions. The imbalance is affecting the governing molecular structure and environmental conditions on Earth. The document argues that electricity is the primary cause of ozone depletion and that increased geological activity results from the Earth trying to regain magnetic balance from human disruptions to its energy grid.

How Small is a Nanometer?
The meter (m) is the basic unit of length in the metric system, and a nanometer is one
billionth of a meter. It's easy for us to visualize a meter; that’s about 3 feet. But a
billionth of that? It’s a scale so different from what we're used to that it's difficult to
imagine.
What Are Common Size Units, and Where is the Nanoscale Relative to Them?

Nanoscience is the study and development of materials and structures in the range of 1
nm (10-9 m) to 100 nanometers (100 x 10-9 = 10-7 m) and the unique properties that arise
at that scale. That is small! At the nanoscale, we are manipulating objects that are more
than one-millionth the size of the period at the end of this sentence.
What if We Measured the Size of Various Objects in Terms of Nanometers?
A typical atom is anywhere from 0.1 to 0.5 nanometers in diameter. DNA molecules are
about 2.5 nanometers wide. Most proteins are about 10 nanometers wide, and a typical
virus is about 100 nanometers wide. A bacterium is about 1000 nanometers. Human
cells, such as red blood cells, are about 10,000 nanometers across. At 100,000
nanometers, the width of a human hair seems gigantic. The head of a pin is about a
million nanometers wide. An adult man who is 2 meters tall (6 feet 5 inches) is about 2
billion nanometers tall!

No, smallness alone doesn’t account for all the interest in the nanoscale. Nanoscale
structures push the envelope of physics, moving into the strange world of quantum

the Brownian motion of these particles now becomes important. Nanosized particles of

The document discusses methods for studying quantum dynamics, localization, and quantum machine learning. It is divided into four parts. Part I develops numerical and analytical methods for studying complex quantum systems and their dynamics. Part II explores scenarios where dynamics is slow and information is localized, focusing on disorder-induced and kinetically constrained localization. Part III designs thermodynamic protocols to speed up thermalization while keeping dissipated work constant. Part IV examines intersections between tensor network methods and machine learning, applying techniques like neural network quantum states and tensor networks to problems in machine learning and approximating probability distributions.
ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Nanoscience is the study and development of materials and structures in the range of 1
nm (10-9 m) to 100 nanometers (100 x 10-9 = 10-7 m) and the unique properties that arise
at that scale. That is small! At the nanoscale, we are manipulating objects that are more
than one-millionth the size of the period at the end of this sentence.
What if We Measured the Size of Various Objects in Terms of Nanometers?
A typical atom is anywhere from 0.1 to 0.5 nanometers in diameter. DNA molecules are
about 2.5 nanometers wide. Most proteins are about 10 nanometers wide, and a typical
virus is about 100 nanometers wide. A bacterium is about 1000 nanometers. Human
cells, such as red blood cells, are about 10,000 nanometers across. At 100,000
nanometers, the width of a human hair seems gigantic. The head of a pin is about a
million nanometers wide. An adult man who is 2 meters tall (6 feet 5 inches) is about 2
billion nanometers tall!

So is That What Nanoscience is All About––Smallness?
No, smallness alone doesn’t account for all the interest in the nanoscale. Nanoscale
structures push the envelope of physics, moving into the strange world of quantum
mechanics. For nanoparticles, gravity hardly matters due to their small mass. However,
the Brownian motion of these particles now becomes important. Nanosized particles of
any given substance exhibit differen ...
The document discusses methods for studying quantum dynamics, localization, and quantum machine learning. It is divided into four parts. Part I develops numerical and analytical methods for studying complex quantum systems and their dynamics. Part II explores scenarios where dynamics is slow and information is localized, focusing on disorder-induced and kinetically constrained localization. Part III designs thermodynamic protocols to speed up thermalization while keeping dissipated work constant. Part IV examines intersections between tensor network methods and machine learning, applying techniques like neural network quantum states and tensor networks to problems in machine learning and approximating probability distributions.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
The cost of acquiring information by natural selectionCarl Bergstrom
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
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. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.
