This document provides an overview of the concepts of pokeball throwing, Pikachu's Thunderbolt, and Charmander's Flamethrower from the physics perspective of the Pokémon universe. It first explains pokeball throwing as an example of projectile motion under gravity. It then analyzes Pikachu's Thunderbolt by comparing Pikachu to a storm cloud that generates lightning through charge polarization and stepped leaders. Finally, it depicts Charmander's Flamethrower by likening Charmander to a fire breather that expels flaming fuel from its mouth through an exothermic reaction. Word problems are also included for each concept.
Quality of light refers to the hue of light at different times of day. Twilight produces a bluish hue that is good for eerie photos, while dawn gives an orange hue and vibrant colors. Morning light is darker and cooler than sunrise, making it good for foggy scenes. Afternoon light is the brightest and most natural, creating dramatic shadows. Examples show how photos of the same subject look different at 2 PM, 4 PM, and 5 PM due to changing light quality.
The document discusses various physics concepts related to the wave-particle duality of light, including interference, diffraction, polarization, and the photoelectric effect. It provides examples of these concepts, such as thin film interference seen in soap bubbles and discusses experiments like the Michelson-Morley experiment and LIGO that study properties of light and gravity waves. The key point is that light must be understood as both a wave and particle based on experimental evidence.
The document summarizes key concepts about high mass stars and binary systems from sections 22.1, 22.2, and 23.5 of the textbook. It notes that high mass stars (>10 solar masses) end their lives as Type II supernovae, sometimes gamma-ray bursters. Binary systems produce novae, Type Ia supernovae, x-ray binaries, and x-ray bursters. All stars enrich the interstellar medium with heavier elements through their evolution and deaths. The goal is to answer fundamental questions about the universe and our origins.
Einstein originally introduced the cosmological constant to allow for a static universe, but its discovery that the universe is expanding led him to call it his "biggest blunder". Observations of type Ia supernovae revealed that the expansion of the universe is accelerating, suggesting a form of dark energy is driving acceleration. The cause of the cosmological constant and dark energy remains poorly understood and a major focus of research, with future satellite missions like SNAP seeking more data from distant supernovae to help explain the mysterious force accelerating cosmic expansion.
Light is a form of energy that is essential to life. It can be produced from other forms of energy or be reflected by objects. There are two types of light - luminous objects that produce their own light, and non-luminous objects that reflect light. Light travels as waves and particles and is part of the electromagnetic spectrum, which includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays. Light reflects off surfaces like mirrors according to the law of reflection.
This document discusses Einstein's theories of special and general relativity and how they relate to the concepts of time dilation, length contraction, and potential methods for time travel. It provides explanations of key ideas in relativity such as how mass curves spacetime according to general relativity and how the laws of physics are the same in any inertial frame under special relativity. Several hypothetical methods for time travel are also presented, including cosmic strings, wormholes, Hawking's train, and an Alcubierre drive.

This document discusses research being done by Robert Ehrlich on the possibility that neutrinos may be tachyons, or hypothetical particles that can travel faster than light. Ehrlich believes that neutrinos, specifically the electron neutrino, may have a mass that would be consistent with it being a tachyon. He summarizes 6 observations from particle physics, cosmology and cosmic ray data that are all consistent with the electron neutrino having the mass of a tachyon. Definitive proof could come from the Katrin experiment measuring tritium beta decay or from observing fine structure in supernova neutrino signals.

The document discusses concepts in quantum mechanics including wave-particle duality, the uncertainty principle, and quantum superposition. It argues that all possible physical universes are constructs of information resulting from internally consistent sets of mathematical forms. Space-time and the physical world are not fundamental but rather emerge from more basic informational structures described by quantum theory and relativity.

Title: Quantum Mechanics Dilemmas
Organized by the Knowledge Diffusion Network
Time: Tuesday, December 11th , 2007.
Location: Department of Physics, Sharif University of Technology, Tehran
The document discusses whether time is quantized in the same way that space is quantized in quantum mechanics. It notes that John Ashmead of the organization "Time and Quantum Mechanics" has raised this question. The document does not provide any conclusions but opens up the question of whether time could be treated similarly to space and be broken into discrete units or quanta in a theory that combines quantum mechanics and relativity.
Alice and Bob’s quest through the fascinating quantum mechanics world as a way to avoid archvilainess Eve eavesdropping. In 1994, Peter Shor showed that many of the cryptosystems used today can be broken using a quantum computer. This idea will be explained together with a short overview of qubit systems. Next, we will see how quantum computing gives rise to the possibility of quantum key distribution with unparalleled security. We will end with a brief discussion on post-quantum cryptography concepts.

Mathematical Formulation of Quantum Mechanics rbmaitri123
This document discusses the mathematical formulation of quantum mechanics. It describes how quantum systems are represented using linear algebra concepts such as Hilbert spaces and operators. Physical states are represented by unit vectors in a Hilbert space. Observables are represented by Hermitian operators whose eigenvalues correspond to possible measurement outcomes. Dynamics are governed by Schrodinger's equation, which describes how states evolve over time.
Experimental demonstration of continuous variable quantum key distribution ov...wtyru1989
This document discusses the practical limitations of quantum key distribution (QKD) including speed, distance, security, and deployment challenges. It presents two QKD technologies - discrete variable and continuous variable - and focuses on improving the performance of continuous variable QKD through techniques like multidimensional reconciliation codes, virtual channel analysis, and accounting for finite key sizes in security proofs. Experimental results demonstrate a continuous variable QKD system over 80km of fiber with key rates of over 100 bits/second.
Presentation used to defend the PhD thesis: "Lie systems and applications to Quantum Mechanics", held in Zaragoza Spain on 23th October 2009.
Atoms, quanta,and qubits: Atomism in quantum mechanics and informationVasil Penchev
The original conception of atomism suggests “atoms”, which cannot be divided more into composing parts. However, the name “atom” in physics is reserved for entities, which can be divided into electrons, protons, neutrons and other “elementary particles”, some of which are in turn compounded by other, “more elementary” ones. Instead of this, quantum mechanics is grounded on the actually indivisible quanta of action limited by the fundamental Planck constant. It resolves the problem of how both discrete and continuous (even smooth) to be described uniformly and invariantly in thus. Quantum mechanics can be interpreted in terms of quantum information. Qubit is the indivisible unit (“atom”) of quantum information. The imagery of atomism in modern physics moves from atoms of matter (or energy) via “atoms” (quanta) of action to “atoms” (qubits) of quantum information. This is a conceptual shift in the cognition of reality to terms of information, choice, and time.
Charge Quantization and Magnetic MonopolesArpan Saha
This talk, given as a part of the Annual Seminar Weekend 2011, IIT Bombay, dealt with a homotopy-based
variant of the argument Dirac provided to show that the existence of a single magnetic monopole in the Universe
is a sufficient condition for the quantization of electric charge.
This document discusses magnetic monopoles and solitons in field theory. It summarizes that solitons are finite-energy, non-dissipative solutions to classical wave equations that arise in non-linear theories. Magnetic monopoles can be constructed from potentials that have Dirac string singularities, requiring the Dirac quantization condition where magnetic charge is quantized. Several models are described where magnetic monopoles arise, including the 't Hooft-Polyakov model in 3+1 dimensions, where the mass of monopoles is related to the gauge boson mass. To date, no magnetic monopoles have been observed experimentally.
Dark matter and dark energy make up 95% of the universe. Dark matter is an undetected form of matter that exerts gravitational pull but does not emit or interact with light. Its existence is inferred from its gravitational effects, such as the rotation speeds of galaxies. Dark energy is driving the accelerating expansion of the universe according to Hubble's law, contradicting the expected eventual gravitational collapse. While their effects can be observed, the true nature of dark matter and dark energy remain mysterious, as they have not been directly detected, and may hold potential future applications in spacecraft propulsion if their properties can be better understood.
1. The document summarizes research on quantum effects in nanomagnetism, including single domain particles, molecular magnets, and superconductors.
2. It discusses quantum tunneling of magnetization in single domain particles and molecular magnets, where the spin can tunnel through an anisotropy barrier.
3. Resonant spin tunneling is observed in molecular magnets at certain magnetic field values where spin energy levels are degenerate, allowing quantum superposition and tunneling.
4. Other topics covered include quantum magnetic deflagration, superradiance, magnetic vortices, and quantum effects in type-I superconductors such as topological hysteresis and flux penetration/expulsion patterns
The document discusses quantum numbers and their role in describing quantum states of electrons in atoms. It provides details on the principal quantum number n, the azimuthal quantum number l, the magnetic quantum number m, and the spin quantum number s. It also discusses the scientists who contributed to the development of these concepts, including Otto Stern, Walther Gerlach, and their Stern-Gerlach experiment demonstrating spin, as well as Wolfgang Pauli and his formulation of the Pauli exclusion principle.
The document provides an overview of the EPR paradox proposed by Einstein, Podolsky and Rosen in 1935. The key points are:
1) The EPR paradox uses a thought experiment involving two entangled particles to argue that quantum mechanics provides an incomplete description of physical reality.
2) By measuring properties of one particle, corresponding properties of the distant entangled particle can be known instantaneously, appearing to violate relativistic constraints on information transfer.
3) While Einstein believed there were "hidden variables" not accounted for in quantum mechanics, experiments have verified quantum mechanics and shown that measurements do not reveal pre-existing states.
120519 ITS: Copenhagen interpretation in quantum mechanicsHyunjung Kim
The Copenhagen interpretation in quantum mechanics discusses the wave probability interpretation, Schrodinger's cat paradox, the EPR paradox and Bell's inequality, and quantum tic tac toe. It addresses how the wave probability interpretation describes the likelihood of finding a particle's location, and explores paradoxes that question the completeness of quantum mechanics like Schrodinger's cat and the EPR paradox tested by Bell's inequality.
The Quantum Internet: Hype or the Next StepJohn Ashmead
What do we mean by the quantum internet? Why do we need more than just quantum computing? What are quantum cryptography, quantum key distribution, quantum sensors? How are these concepts entangled? What are the advantages of the quantum internet? key problems? Who will get to use it? And do we have just a bunch of interesting technologies that all have quantum in their name or can the whole be more than the sum of its parts?

We will look at Model-View-Controller architecture; what tools you need to get started; how to work with the online tutorials; what kind of workflow to use; and which tasks to let Ruby-on-Rails handle versus which are better done by PostgreSQL.

Time dispersion in quantum mechanics -- Philcon 2019 versionJohn Ashmead
We know from quantum mechanics that space is fuzzy, that particles don’t have a well-defined position in space. And we know from special relativity that time and space are interchangeable. But if they are interchangeable, shouldn’t time be fuzzy as well? Shouldn’t the rules of quantum mechanics apply — along the time dimension? Bohr and Einstein — who disagreed on so much — nevertheless agreed on this.
Is time fuzzy? In quantum mechanics space is fuzzy. And in special relativity time and space are interchangeable. But if time and space are interchangeable, shouldnt time be fuzzy as well? Shouldnt quantum mechanics apply -- to time? Thanks to recent technical advances we can put this to the test. We ask: How do you get a clock in a box? How do you interfere with time? When is one slit better than two? And what happens at the intersection of time and quantum mechanics?
Why do we want to go? How do we get there? How do we live there? What might we find? What are the dangers: radiation, low gravity, dust, our fellow humans? Is there life on Mars now? Was there once? and did our own evolution actually start on Mars?
Practical Telepathy: The Science & Engineering of Mind-ReadingJohn Ashmead
The document discusses the history and future of telepathy and mind reading. It covers early concepts of mentalism and ESP, scientific studies by Rhine and modern brain imaging techniques like fMRI. The document also discusses emerging technologies that could enable two-way mind-to-mind communication through brain interfaces and issues around privacy and control of one's thoughts. It presents both opportunities like helping disabled people and risks of not fully understanding the complex human mind.
From Startup to Mature Company: PostgreSQL Tips and techniquesJohn Ashmead
This talk is for people relatively new to PostgreSQL who are wondering:
How do I get going with PostgreSQL -- in a way that won’t create problems later on!
We’ll go over best practice in:
Table design
Indexing
PostgreSQL types
Stored procedures -- when & how to use, when not
Triggers
How to work with a web framework (i.e. Ruby-on-Rails): what works belongs in the framework, what should be done in the database
Error & exception management
Doing the right amount of planning
Why you might want to build the help system first, and use it to help build the rest.
Nistica has its ownership in Japan, engineering in New Jersey, & manufacturing in Vietnam so we’ll take a special look at:
Handling different languages & character sets
Timestamps & time zones
How to sync data from one part of the world to another without letting data fall on the floor or creating infinite loopiness.
Nistica has gone from startup to world player in the manufacture of optical switches. It has run its manufacturing on PostgreSQL from the start, using PostgreSQL to drive every step from assembly to quality assurance & tracking all part data in the database.
Going from the ad hoc procedures appropriate for a startup to the disciplined approaches required by the world market has taught us a lot about how to get the best out of PostgreSQL.
We’ve learned a lot from the PostgreSQL community; now we’d like to share some of what we’ve learned from our experience.
Practical Telepathy: The Science & Engineering of Mind-ReadingJohn Ashmead
From van Vogt's Slan to Willis's Crosstalk, telepathy has been a staple of science fiction. But what are the real world chances of reading another person's mind? With MRI & PET scans we can see what images a person is thinking of, with brain implants we can help the blind to see, and -- the way the science is going -- we are only a half-step away from direct mind-to-mind communication. Nothing to worry about here!
What are StarGates? Why & wither wormholes? Dangers of sphaghettification. How to build a wormhole? Negative energy & vortices. At the edge of testable. Today, a bridge of birds, tomorrow the cell phone: nearly impossible today, but tomorrow?
Call them Stargates, Jumpgates, Fargates, Hypergates or just an invitation to every unwanted pest from the far reaches of the Galaxy to visit, they're absolutely necessary if we're to have the glorious Science Fiction action we desperately need. Could they actually be built? Modern physics may permit: how to glue black holes together to build a wormhole, how to avoid the dangers of spaghettification, radiation poisoning and paradox noise, and just what would it take to build one in practice.
Quantum dots (QD) are semiconductors made via several possible routes. John Ashmead discusses how they are made, their properties and their applications in research.
Call them Stargates, Jumpgates, Fargates, Hypertubes or just an invitation to every unwanted pest from the far reaches of the Galaxy to visit, they are absolutely necessary if we are to have the glorious Science Fiction action we desperately need. But could they actually be built? We look at what modern physics has to say: how to glue black holes together to build a wormhole, how to avoid the dangers of spaghettification, radiation poisoning, and paradox noise, and just what it would take to build one in practice.
The document discusses three stories that involve time travel: The Anubis Gates, about a steampunk time machine; 3 Days to Never, about a bicycle-based time machine and a girl transported through time; and Burning Gates of Anubis, a sequel to The Anubis Gates. It provides summaries of the time travel plots and devices in each story.
We look at the history of the multiverse, the big bang theory, the problem of fine-tuning, how it is solved by the anthropic principle, how the combination of eternal inflation & string theory might create many universes, and a bit of discussion as to the odds of the multiverse being true.
We review the double slit experiment, the "central mystery" of quantum mechanics as Feynman put it. We included a number of animations, including some from Larry Latham specially done for this presentation! Unfortunately the animations don't seem to post correctly to slideshare, alas.
How to convert from MySQL to PostgreSQL: discuss history of each, current status, when you might wish to convert, what might motivate you to convert, & how to do so. With references.
The document describes 7 stories from the author's career as a programmer. Each story highlights a different challenge solved through creative technical solutions: 1) Automating stored procedure generation. 2) Generating joins by reading metadata. 3) Mapping fonts to work around software limitations. 4) Creating an easy-to-use program for a coworker with disabilities. 5) Writing a file checking utility in a day. 6) Creating a color-coded report to identify issues across departments. 7) Monitoring remote switches and troubleshooting connection issues.

Introduction of Cybersecurity with OSS at Code Europe 2024Hiroshi SHIBATA
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
HCL Notes and Domino License Cost Reduction in the World of DLAUpanagenda
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered
- Reducing license cost by finding and fixing misconfigurations and superfluous accounts
- How do CCB and CCX licenses really work?
- Understanding the DLAU tool and how to best utilize it
- Tips for common problem areas, like team mailboxes, functional/test users, etc
- Practical examples and best practices to implement right away

The warp drive: hyper-fast travel within general
relativity
Sunday, November 29, 2009
36. Krasnikov TUBE
If the Alcubierre space warp moves faster than the velocity of light, it
cannot be controlled from inside. Per Krasnikov, at superluminal speeds the
interior of the bubble is causally isolated from its surface and exterior.
Photons cannot pass from the inside to the outside. Therefore, there would be
no way of controlling the space warp—of stopping, starting or steering.
Krasnikov's alternative is to create a space warp behind the space ship as
it travels at near lightspeed to some distant star system, and then use the
"tube" thus created for the return trip. This distortion of space has an
interesting property for the return trip: it gets you back home shortly
after you left, no matter how far you go.

37. Warp Drive: A New Approach
Richard K Obousy and Gerald Cleaver∗
Baylor University, Waco, Texas, 76706, USA
(Dated: February 11, 2008)
Certain classes of higher dimensional models suggest that the Casimir
effect is a candidate for the cosmological constant. In this paper we
demonstrate that a sufficiently advanced civilization could, in principal,
manipulate the radius of the extra dimension to locally adjust the value of
the cosmological constant. This adjustment could be tuned to generate an
expansion/contraction of spacetime around a spacecraft creating an
exotic form of field-propulsion. Due to the fact that spacetime expansion
itself is not restricted by relativity, a faster-than-light ‘warp drive’ could
be created. Calculations of the energy requirements of such a drive are
performed and an ‘ultimate’ speed limit, based on the Planckian limits on
the size of the extra dimensions is found.

"Warp drive" spacetimes are useful as
"gedanken-experiments" that force us to

In this war it wasn't remarkable to have

Base that occurred every day. And it wasn't
unusual to have news from the future. In fact,
sending messages to command posts back in the
past was a deliberate combat tactic. The flow of
information from future to past wasn't perfect;
it all depended on complicated geometries of
trajectories and FTL leaps.
