Sun Light and Sun Atoms
*
All cannot live on the piazza,
but everyone may enjoy the sun.
- Italian proverb
*
Earthbound humans knew almost nothing about the sun until the early 19th century.Then, the German optician Joseph von Fraunhofer studied the solar spectrum and found it interrupted by some 600 dark lines.These represented colors that are missing from the sunlight Earth receives.
*
As scientists realized that these spectral lines were related to the presence of various types of atoms in the sun’s atmosphere, a window finally opened to real understanding of the sun’s nature.
*
In this chapter, you will look through that window—by considering how the sun produces light and how atoms interact with light to make spectral lines.
*
Once you understand that, you will know how astronomers have:Determined the chemical composition of the sunMeasured motions of gas on the sun’s surface and in its atmosphereDetected magnetic fields that drive the sun’s cycle of activity
*
The Sun—Basic CharacteristicsIn its general properties, the sun is very simple. It is a great ball of hot gas held together by its own gravity. The tremendously hot gas inside the sun has such a high pressure that it would explode were it not for its own confining gravity. The same gravity would make it collapse into a small, dense body were it not so hot inside.
*
Like a soap bubble, the sun is a simple structure balanced between opposing forces that, if unbalanced, would destroy it.
The Sun—Basic Characteristics
*
These dramatic statements are also true for other stars.So, you can study the sun for insight into the rest of the stars in the universe.
The Sun—Basic Characteristics
*
Another reason to study the sun is that life on Earth depends critically on the sun. Very small changes in the sun’s luminosity can alter Earth’s climate.A slightly larger change might make Earth uninhabitable.Nearly all of Earth’s energy comes from the sun—the energy in oil, gasoline, coal, and even wood is merely stored sunlight.
The Sun—Basic Characteristics
*
Furthermore, the sun’s atmosphere of very thin gas extends past Earth’s position.Changes in that atmosphere—such as eruptions or magnetic storms—can have a direct effect on Earth.
The Sun—Basic Characteristics
*
When you watch the sun set in the west, you see a glowing disk that is 150 million kilometers (93 million miles) from Earth and has a diameter 109 times Earth’s.How do you know this?
Distance and Size
*
You have learned that, thanks to the work of Johannes Kepler in the 17th century, the relative sizes of the orbits of the planets were already known in astronomical units.1 AU is equal to the average distance of the sun from Earth.
Distance and Size
*
Also, you have learned that the true distance of a nearby object can be calculated from the size of the apparent shift in its position relative to the background as seen from ...
Piezoelectric Materials and Applications
This presentation by Abhishek Dubey provides a very nice primer of Piezoelectric Materials and Applications.
14 lecture outline
The Sun shines through nuclear fusion in its core. The core is hot and dense enough for hydrogen to fuse into helium via the proton-proton chain reaction. This nuclear fusion releases energy that gradually makes its way to the surface and radiates into space, powering the Sun for billions of years. We know about the Sun's interior structure from mathematical models, observations of solar vibrations, and detections of solar neutrinos. Solar activity like sunspots and solar flares are caused by magnetic fields in the Sun. Bursts of particles from solar activity can disrupt power grids and satellites orbiting Earth. The 11-year solar cycle is due to changes in the Sun's magnetic field over time.
Let the Sunshine In! (Part 1)
This document provides information about the sun in the form of a classroom lesson on earth science. It begins with the day's learning goals which are the characteristics, composition, and phenomena of the sun. Several facts are then listed, such as the sun being 109 times the radius of Earth and having an average surface temperature of 5700°C. The interior and atmospheric layers of the sun are described along with features like sunspots. The document explains that the sun is made primarily of hydrogen and helium created through nuclear fusion, and discusses how spectroscopy is used to determine its composition. It concludes by addressing whether the sun will explode and engulf Earth.

Interstellar chemistry
The document discusses chemistry in the interstellar medium (ISM). It notes that chemistry in the ISM occurs under very different physical conditions than on Earth, including low pressure, extreme temperatures, and high-energy radiation. Quantum tunneling allows chemical reactions to occur even in these hostile environments by allowing particles to tunnel through energy barriers. The document provides examples of organic molecules and cosmic dust found in the ISM through astrochemical analysis.
Physics
This document summarizes key concepts in physics. It discusses how Kepler examined planetary motion data to show elliptical rather than circular orbits. It also describes the development of quantum mechanics to explain atomic phenomena, Rutherford's nuclear model of the atom, and Dirac's theoretical prediction of antimatter later confirmed by Anderson. The document defines physics as the study of natural laws and their manifestations, and discusses the fields of classical and modern physics including mechanics, electromagnetism, optics, and thermodynamics. It also outlines the four fundamental forces in nature and explores the nature of physical laws like conservation of energy.
Module 2 (Envi 11)MAURILLO C. .pdf
The document discusses the nature and organization of matter from the atomic to cellular level.

4. The formation of the Earth from a large dust cloud approximately 4.54 billion years ago and how its interior structure developed over time, including the magnetic field that protects it.
PS-Week-1-Origin-of-the-Universe-Part-1.pptx
This document discusses elements, atoms, and the Big Bang theory of the origin of the universe. It describes how cosmology studies the origin and evolution of the universe. According to the Big Bang theory, the universe began as a singularity around 13.7 billion years ago and has been expanding ever since. The early universe formed light elements through nucleosynthesis, then heavier elements as stars formed and exploded in supernovae. Evidence for the Big Bang includes the redshift of distant galaxies and the cosmic microwave background radiation.
Energy types
Here are the steps to solve the roller coaster energy problems:
1. PE at point A = mgh = (20 kg)(10 m/s^2)(250 m) = 50,000 J
2. KE at point A = 0 J (velocity is 0 m/s at the top)
3. ME at point A = PE + KE = 50,000 J + 0 J = 50,000 J
4. KE at point B = 1/2mv^2 = 1/2(20 kg)(200 m/s)^2 = 40,000 J
5. ME at point C = ME is conserved. ME at point A was 50,000 J.

Ch14
The document discusses the life cycles of stars from birth to death. It explains that stars are born from collapsing nebulae and spend most of their lives on the main sequence fusing hydrogen into helium through nuclear fusion reactions in their cores. Eventually a star's nuclear fuel will be depleted, causing it to leave the main sequence and expand into a red giant. The fate of a star depends on its mass, with smaller stars becoming white dwarfs and larger stars ending their lives in supernova explosions, leaving behind neutron stars or black holes.
Radioactivity.pptx
radioactivity is the act of emitting radiation spontaneously. This is done by an atomic nucleus that, for some reason, is unstable; it "wants" to give up some energy in order to shift to a more stable configuration.
02 Matter Is Atoms That Move After Class
1. The document discusses various topics in physics including Brownian motion, atoms, and scanning tunneling microscopy.
2. Brownian motion provides evidence for the existence of atoms by showing microscopic particles jiggling in liquid.
3. Scanning tunneling microscopy allows viewing and manipulating individual atoms by measuring electron tunneling current.
Physical Geography Lecture 04.5 - Earth's Atmosphere 101016
The document discusses key concepts about Earth's atmosphere including:
1. The atmosphere is composed primarily of nitrogen and oxygen gases. It also contains variable amounts of gases like carbon dioxide and ozone that influence climate.
2. Solar radiation is processed as it passes through the atmosphere, being scattered, absorbed, or transmitted. Particulates play an important role by reflecting or absorbing sunlight.
3. Temperature varies with altitude, decreasing in the troposphere due to conduction and the environmental lapse rate, and increasing in the stratosphere due to ozone absorption of UV light.
Physics in our lives
This document provides an introduction to physics and highlights some of its key concepts and applications. It begins by discussing how humans developed advanced brains and the vision to explore the mysteries of nature, leading to the emergence of physics. Physics has solved mysteries and improved lifestyle through concepts like mechanics, electricity, magnetism, waves, and modern physics. It gives examples of physics principles at work in everyday objects and phenomena like speakers, lightning rods, and the woo-woo sound of boiling water.
Electronics 10.pptx
This document provides an introduction to electron theory and electricity. It explains that electricity is caused by the flow of electrons and defines electrons as negatively charged particles that orbit the nucleus of atoms. The document discusses how electrons can become free or bound, and how atoms become ions through gaining or losing electrons via ionization. It also briefly introduces static electricity and how rubbing certain materials can cause the transfer of electrons, resulting in an attraction between objects. The overall purpose is to explain the fundamentals of electricity by describing the structure of atoms and the role of electrons.
Light em&bigbang
The document discusses the electromagnetic spectrum and the Big Bang theory. It explains that electromagnetic radiation consists of photons with different wavelengths and energies. The farther away objects are observed, the farther back in time we see them due to the finite speed of light. Measurements of the cosmic microwave background radiation provide evidence that the universe began in a hot, dense state around 13.7 billion years ago and has been expanding and cooling ever since, as predicted by the Big Bang theory.

An improved modulation technique suitable for a three level flying capacitor ...
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

This document serves as a comprehensive step-by-step guide on how to effectively use PyCharm for remote debugging of the Windows Subsystem for Linux (WSL) on a local Windows machine. It meticulously outlines several critical steps in the process, starting with the crucial task of enabling permissions, followed by the installation and configuration of WSL.
The guide then proceeds to explain how to set up the SSH service within the WSL environment, an integral part of the process. Alongside this, it also provides detailed instructions on how to modify the inbound rules of the Windows firewall to facilitate the process, ensuring that there are no connectivity issues that could potentially hinder the debugging process.
The document further emphasizes on the importance of checking the connection between the Windows and WSL environments, providing instructions on how to ensure that the connection is optimal and ready for remote debugging.
It also offers an in-depth guide on how to configure the WSL interpreter and files within the PyCharm environment. This is essential for ensuring that the debugging process is set up correctly and that the program can be run effectively within the WSL terminal.
Additionally, the document provides guidance on how to set up breakpoints for debugging, a fundamental aspect of the debugging process which allows the developer to stop the execution of their code at certain points and inspect their program at those stages.
Finally, the document concludes by providing a link to a reference blog. This blog offers additional information and guidance on configuring the remote Python interpreter in PyCharm, providing the reader with a well-rounded understanding of the process.
Redefining brain tumor segmentation: a cutting-edge convolutional neural netw...
Medical image analysis has witnessed significant advancements with deep learning techniques. In the domain of brain tumor segmentation, the ability to
precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.
Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
