The document discusses the development of scientific theories and experiments regarding atoms, light, and quantum mechanics. It describes early experiments and observations that led to discoveries such as the planetary model of the atom, the particle nature of light, and wave-particle duality. Later, quantum mechanics was developed to explain the intrinsic unpredictability of atomic behaviors and experiments such as the double slit experiment.
1. The document discusses whether science will ever be able to fully explain everything through its predictive testing methodology.
2. While science has made tremendous advances in explaining various natural phenomena, every new discovery leads to new questions, and science may be inherently limited in answering fundamental questions about meaning and purpose.
3. Some mysteries like "magic numbers" that appear throughout nature and the simplicity of laws governing the universe cannot be fully explained by science alone. Science may not have the tools to answer all questions.
The document discusses several topics related to science education including:
- GEIS students visiting school laboratories to conduct experiments on properties of liquids, forces and flight, and chemicals. The students were observed to be enthusiastic learners who work well independently and in groups.
- The historical image of scientists as eccentric versus how science is actually everywhere in our daily lives.
- The early challenges in detecting neutrinos from the Sun due to the difficulty of the experiment and need for careful experimental design to control variables.

The document discusses the trend of "omni-colleagues," where companies are re-integrating human employees into digital interfaces and customer experiences. It notes that while companies had been moving towards more automated and robotic customer service, replacing human interactions was not working. Specifically:
- Companies are emphasizing their employees as "colleagues" rather than "staff" to build camaraderie between employees and customers. Some services now rate and review individual employees.
- Companies are providing digital tools to employees but also training them in social skills to have more meaningful interactions with customers.
- Moving forward, companies will look to equip employees to take meaningful actions for users through digital tools, making employees "omni-

The concept of 'time' - (Modern literature)bhavnabaraiya
This document summarizes key elements and themes from Samuel Beckett's play Waiting for Godot. It discusses how:
1) The play presents a logical problem as the two main characters do not remember what they did the day before and fail to recognize their surroundings.
2) Nothing new happens in Act II as scenes repeat themselves and the characters suffer from memory loss, unaware of the repetition.
3) The tramps try to stay occupied by engaging in trivial activities and conversations to pass the time but ultimately remain in the same place.
4) They are codependent on each other for company to endure their meaningless existence.
5) The play emphasizes how waiting is a universal human experience

The document discusses the structure of atoms and the periodic table. It describes subatomic particles like protons, neutrons, and electrons. Atoms are made up of a nucleus containing protons and neutrons, surrounded by electrons. The periodic table organizes elements based on their atomic structure, including the number of protons and electrons. Elements are grouped according to their chemical properties, which depend on the number of electrons in their outer shell. The periodic table illustrates recurring trends in how elements behave and has helped explain atomic structure.
Shamit Kachru on "Extra dimensions" at a LASERpiero scaruffi
The document discusses the idea in theoretical physics that there may be more than three spatial dimensions. Many physicists now believe this could help explain and unify fundamental forces and particles. Originally proposed in the 1920s, theories with extra dimensions beyond our everyday experience could give rise to forces like electromagnetism from higher-dimensional gravity. Modern string theory also requires the existence of 6 or 7 additional dimensions. If extra dimensions exist, they would have to be small enough to have avoided detection so far. Finding evidence of extra dimensions could help geometrize our understanding of physics.

The cosmic gorilla effect or the problem of undetected non terrestrial intell...Sérgio Sacani
This document discusses how human psychology and neurophysiology may be unintentionally biasing the search for non-terrestrial intelligence (NTI). It points out that focusing only on radio signals and known physics limits our perspective, and that more advanced civilizations could exploit dark matter or exist in other dimensions. It also suggests that focusing attention narrowly could cause us to miss obvious signs of NTI, similar to the "invisible gorilla" experiment on inattentional blindness. Broadening our concepts of what NTI may look and expanding our search across the electromagnetic spectrum and beyond known physics may improve our chances of detection.
The document summarizes a book titled "The Cosmic Century: A History of Astrophysics and Cosmology" by Malcolm S. Longair. It discusses how the book charts the development of our understanding of astronomical objects from astronomy to modern astrophysics and cosmology over the past century. It describes how new observational techniques and the application of modern physics led to advances. The review argues the historical approach taken in the book is useful, as it provides context for the struggles and discoveries in the field and allows readers to understand plausible theories that did not end up being correct. However, it notes the book could have emphasized two specific contributors' roles more. The review concludes the book will be appreciated for providing a sound overview of the history and
El Británico Roger Penrose por sus desarrollos teóricos sobre agujeros negros. La Estadounidense Andrea Ghez y el Alemán Reinhald Genzel por el hallazgo de un objeto súper masivo y compacto en el centro de nuestra galaxia.

Tres investigadores han sido galardonados con el premio Nobel de Física de este año por sus descubrimientos sobre estos fenómenos supermasivos. Roger Penrose por demostrar su existencia según la teoría de la relatividad general y Reinhard Genzel y Andrea Ghez por demostrar que los agujeros negros son capaces de interferir en las órbitas de estrellas cercanas.
Los astrónomos Roger Penrose, Reinhard Genzel y Andrea Ghez se han hecho con el premio Nobel de Física de 2020. El primero de los científicos ha obtenido la mitad del galardón por la demostración fáctica de la existencia de los agujeros negros, siguiendo los preceptos de la teoría de la relatividad de Einstein. Los otros dos investigadores han sido distinguidos por el descubrimiento de un objeto supermasivo en el centro de la Vía Láctea, a unos 26.000 años luz de nuestro planeta.
Reinhard Genzel y Andrea Ghez descubrieron un agujero negro en el centro de la Vía Láctea comprobando la velocidad de las órbitas de sus estrellas circundantes.
“Los descubrimientos de los galardonados de este año han abierto nuevos caminos en el estudio de objetos compactos y supermasivos. Pero estos objetos exóticos todavía plantean muchas preguntas que piden respuestas y plantean nuevos retos de investigación en el futuro, no solo sobre la estructura interna de estos objetos masivos, sino también sobre cómo usar la teoría de la relatividad general en condiciones extremas”, ha declarado David Haviland, presidente del Comité Nobel de Física.
A preponderance of scientific evidence over the last hundred years tells us that our galaxy is filled with an unknown substance called dark matter. In fact, there is five times as much dark matter in the universe than there is ordinary matter: we are swimming in an ocean of dark matter and we have no firm idea what it is. We suspect that dark matter is composed of undiscovered elementary particles whose properties may, in turn, unlock some of the most pressing open questions in fundamental physics. So why haven't we figured out how to study dark matter in the lab, and why should we be optimistic that we may make progress in the coming decades?
Proceedings of a talk given at the American Translators Association's 53rd conference.
Abstract:
Recently, the news outlets were buzzing with excitement about the possible discovery of a new particle at the Large Hadron Collider (LHC). The LHC at CERN is not only the world's largest machine and fridge, but also home of the world’s largest international scientific collaborations, with several thousand scientists from over 100 different nations. As such, the underlying science may be of interest to linguists. This paper presents a basic overview over our current knowledge of the universe and aims at explaining the big fuss about the search for the Higgs (also known as the “God particle”) and its possible connection to dark matter. No knowledge of advanced mathematics or physics is required to read this paper. For readers who want to know more, some references and recommendations for further reading are included at the end.
1. The document discusses whether science will ever be able to fully explain everything through its predictive testing methodology.
2. While science has made tremendous advances in explaining various natural phenomena, every new discovery leads to new questions, and science may be inherently limited in answering fundamental questions about meaning and purpose.
3. Some mysteries like "magic numbers" that appear throughout nature and the simplicity of laws governing the universe cannot be fully explained by science alone. Science may not have the tools to answer all questions.
Black holes are regions of space with immense gravitational pull that not even light can escape. They have a boundary called an event horizon inside of which matter becomes infinitely dense. Stephen Hawking theorized that black holes transform what enters them and eject it when they evaporate, while a 2012 doomsday theory claimed a black hole would destroy Earth. Scientists search for black holes by looking for areas with large concentrated mass that emit no light.
This document discusses the history of discoveries related to dark matter and dark energy. It describes how observations over the past 100 years have shown that normal matter only accounts for about 4% of the matter in the universe. The other 96% is believed to be dark matter and dark energy. Evidence from galaxy rotations, gravitational lensing, and galaxy cluster dynamics provides strong evidence for the existence of dark matter, which is believed to be some non-baryonic, non-luminous particle that interacts only through gravity and the weak force.
Black holes were first proposed in the 18th century based on known laws of gravity. They form when massive stars over 20 times the sun's mass undergo gravitational collapse. A black hole is a region of space where gravity is so strong that nothing, not even light, can escape. Theories about black holes include that they are areas where space and time are infinitely curved and density is infinite at the singularity. Scientists continue researching to discover more black holes and learn about their properties.

The document reflects on the author's changing views of physics over time. As a student, they disliked physics classes in 9th and 10th grade because they struggled to understand the equations. However, their view changed when taking undergraduate physics courses over the summer between 10th and 11th grade. They learned new techniques and enjoyed researching problems that did not have immediate solutions. The author also enjoyed helping other students with physics and mathematics, which led them to become a teaching assistant.
2012 was a year of scientific discoveries that revolutionized understanding of the universe. Researchers decoded light from the early universe using sophisticated tools, revealing stars and galaxies from billions of years ago. Finding the Higgs boson particle confirmed theoretical predictions and opened doors to further questions about dark matter and other phenomena. While expanding knowledge, these discoveries also showed the limitations of scientific models and pointed to greater spiritual truths about the universe.
A Deep and Wide Twilight Survey for Asteroids Interior to Earth and VenusSérgio Sacani
This document describes a survey to discover asteroids interior to Earth's and Venus' orbits using the Dark Energy Camera on the Blanco 4m telescope in Chile. The survey has discovered three new asteroids so far, including two rare Atira asteroids completely interior to Earth and one Apollo asteroid crossing Earth's orbit. Two discoveries are estimated to be over 1 km in diameter. The survey has covered 624 square degrees near and interior to Venus' orbit, detecting about 15% of all known Atira asteroids. The survey aims to better understand asteroid populations in the inner solar system to improve models of near-Earth object populations and impact risks.
(1) The document discusses the concepts of emergence and reduction in physics, specifically arguing that they pose a false dichotomy as they are logically independent.
(2) It provides examples where emergence occurs alongside reduction, such as the emergence of classical behavior from quantum mechanics in certain limits, and the emergence of thermodynamic laws and properties from statistical mechanics.
(3) The key point is that reduction, viewed as deduction, allows for novelty through the choices made in taking limits, such as which symmetries to break or states to keep. So emergence and reduction can be compatible.
Talk given at Oxford Philosophy of Physics, LSE's Sigma Club, the Munich Center for Mathematical Philosophy, Carlo Rovelli's 60th birthday conference.
I construe dualities in physics as particular cases of theoretical equivalence. The question then naturally arises whether duality is compatible with emergence. For the the focus of emergence is on novelty rather than on equivalence.
In the first part of the talk, I review recent work dealing with this question. I exhibit two ways in which duality and equivalence can be made compatible, and I give an example of emergence in gauge/gravity dualities: dualities between a theory of gravity in (d+1) dimensions and a quantum field theory (QFT) in d dimensions.
In the second part of the talk, I present new results on the question whether diffeomorphisms in gravity theories emerge from QFTs. I critically assess the following idea, taken from the physics literature: given that (a) the QFT is not a diffeomorphism invariant theory, and that (b) there is a duality between the QFT and the gravity theory, are we entitled to (c) conclude that the diffeomorphisms of the gravity theory emerge from the QFT?
I argue that one must distinguish different kinds of diffeomorphisms: some diffeomorphisms are ‘invisible’ to the QFT: all of the QFT’s quantities are invariant under them, therefore the QFT does not ‘see’ them. But other diffeomorphisms are ‘visible’ to the QFT. The invisible diffeomorphisms prompt a ‘Bulk Argument’, in analogy with the Hole Argument. The analysis of emergence is different for these different kinds of diffeomorphisms, and I discuss the way in which we can speak of emergence of diffeomorphisms in gauge/gravity dualities.
Pittsburgh talk on Emergence and in Gauge/Gravity DualitiesSebastian De Haro
This document discusses emergence and duality in gauge/gravity dualities. It begins by introducing gauge/gravity dualities, which relate a theory of gravity in (d+1) dimensions to a quantum field theory without gravity in d dimensions. The document then discusses two ways in which emergence can occur in theories related by duality: 1) the duality map breaks down at some level of fine-graining, and 2) an approximation scheme is applied to each side of the duality, only holding the duality approximately. Even if gauge/gravity duality is exact, emergence can occur through the second way by approximating the full string theory with a semiclassical gravity theory, where the radial direction corresponds to energy scale
Berlin Slides Dualities and Emergence of Space-Time and GravitySebastian De Haro
Holographic relations between theories have become an important theme in quantum gravity research. These relations entail that a theory without gravity is equivalent to a gravitational theory with an extra spatial dimension. The idea of holography was first proposed in 1993 by ‘t Hooft on the basis of his studies of evaporating black holes. Soon afterwards the holographic AdS/CFT duality was introduced, which since has been intensively studied in the string theory community and beyond. Recently, Verlinde has proposed that Newton’s law of gravitation can be related holographically to the ‘thermodynamics of information’ on screens. I discuss the last two scenarios, with special attention to the status of the holographic relation in them and to the question of whether they make gravity and spacetime emergent. I conclude that only Verlinde’s scheme instantiates emergence in a clear and uncontroversial way. I suggest that a reinterpretation of AdS/CFT may create room for the emergence of spacetime and gravity there as well.

Florence Duality Talk: Reduction and Emergence in Holographic Scenarios for G...Sebastian De Haro
Philosophical talk about the status of dualities and the emergence of gravity in two holographic scenarios: 1) AdS/CFT and 2) Verlinde's scenario of emergent gravity.
Based on recent work on quantum gravity and the holographic principle I argue that, instead of thinking of the universe as a 'bubble out of nothing', we should think of space, time, and gravity as emerging 'out of information'.
The document summarizes a presentation given on January 14, 2012 for AUC Open Day. The presentation covered topics including the first quantum cryptography bank transfer between Vienna City Hall and a bank branch using entangled photons, the wave-particle duality of light and quantum mechanics, Bell's theorem and experiments violating local realism, and applications of quantum cryptography including secure communication using entangled photons. The presentation aimed to explain some counterintuitive aspects of quantum physics.
The document discusses black holes and their implications for physics. It begins by summarizing classical black hole properties, then discusses how quantum mechanics challenges ideas about information loss in black holes. Hawking originally argued black holes destroy information, but later conceded after the discovery of holography and developments in string theory suggested information is preserved at the black hole boundary. The document examines how black holes helped unify relativity and quantum mechanics through concepts like complementarity and the holographic principle.
This document summarizes a talk on recent advances in topological quantum field theory. It discusses holographic duality between gravity theories in (d+1)-dimensional anti-de Sitter space and conformal field theories on the d-dimensional boundary. It describes how boundary conditions in the bulk correspond to sources and expectation values of operators in the boundary CFT. It also discusses techniques for holographic renormalization to regulate divergences and compute finite correlation functions. Finally, it proposes investigating the dynamics of boundary gravitons and gravitational instanton solutions as a way to understand coupling the CFT to dynamical gravity.

Temple of Asclepius in Thrace. Excavation resultsKrassimira Luka
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).

philosophy is dead. Philosophy has not kept up
with modern developments in science, particularly
physics. Scientists have become the bearers
of the torch of discovery in our quest for
knowledge. The purpose of this book is to give the
answers that are suggested by recent discoveries
and theoretical advances. They lead us to a new
picture of the universe and our place in it that is very
different from the traditional one, and
different even from the picture we might have
painted just a decade or two ago. Still, the first
sketches of the new concept can be traced back
almost a century.” (The Grand Design).

board argued that we should not give the
impression that we think that elementary
particle physics is more fundamental than other
fields, because it just tended to enrage our
friends in other areas of physics. The reason we
give the impression that we think that
elementary particle physics is more fundamental
than other branches of physics is because it is. I
do not know how to defend the amounts being

about this.”

which is fundamental to most attempts to unify Einstein's
General Relativity with Quantum Theory. This would be
confirmed by the discovery of super partners to the
particles that we already know. The Superconducting
Super Collider (the SSC) was being built in Texas and
would have reached the energies at which super partners
were expected. However, the United States went
through a fit of feeling poor and canceled the project
half way. At the risk of causing embarrassment, I have
to say I think this was a very short sighted decision. I
hope that the US, and other governments will do better in
the next millennium. (Stephen Hawking, Millennium

54. There is no baby universe branching off, as I once thought. The
information remains firmly in our universe. I’m sorry to disappoint
science fiction fans, but if information is preserved, there is no
possibility of using black holes to travel to other universes. If you
jump into a black hole, your energy will be returned to our universe
but in a mangled form which contains the information about what
you were like but in a state where it can not be easily recognized. It
is like burning an encyclopedia. Information is not lost, if one keeps
the smoke and the ashes. But it is difficult to read. In 1997, Kip
Thorne and I, bet John Preskill that information was lost in black
holes. The loser(s) of the bet were to provide the winner(s) with an
encyclopedia of their own choice, from which information can be
recovered with ease. I gave John an encyclopedia of baseball, but
maybe I should just have given him the ashes.
