Karen Adelan presented on the topic of classical mechanics and energy. Some key points:
- Energy is a conserved quantity that can change forms but is never created or destroyed. It is useful for describing motion when Newton's laws are difficult to apply.
- Kinetic energy is the energy of motion and depends on an object's mass and speed. The work-kinetic energy theorem states that the net work done on an object equals the change in its kinetic energy.
- Potential energy is the energy an object possesses due to its position or state. The work done by a constant force equals the product of force, displacement, and the cosine of the angle between them.
This document discusses normal modes of vibration in a system. It begins by introducing normal modes as patterns of motion where all parts of a system move sinusoidally with the same frequency and fixed phase relation. It then covers normal coordinates and modes, describing them as linear combinations of displacements that decouple the equations of motion into independent oscillations. Symmetric modes involve in-phase motion, while antisymmetric modes involve out-of-phase motion. The document expresses kinetic and potential energies in terms of the normal coordinates, eliminating cross terms between coordinates.

This document discusses capillary action, including:
- Capillary action is the process by which liquids move through narrow spaces due to intermolecular forces. It occurs when a liquid rises in a narrow tube or is drawn into small openings.
- Capillary rise occurs when adhesive forces between a liquid and solid are greater than cohesive forces within the liquid, causing the liquid surface to curve upward. Capillary fall occurs in the opposite case.

The drop weight method specifically measures surface tension based on the weight and radius of drops detached from a tube under constant conditions. Factors affecting surface tension and applications are also discussed.
This document discusses surface tension and methods for measuring surface tension. It defines surface tension as the imbalance of intermolecular forces at a liquid-air interface.

Factors that influence surface tension such as temperature and presence of surfactants are also covered.
1. Rotational inertia is the tendency of a body to resist changes to its angular velocity, just as linear inertia resists changes to linear velocity.
2. Moment of inertia depends on how mass is distributed about an axis of rotation, and is a measure of the difficulty in changing the body's rotational motion. A greater moment of inertia means a greater torque is required to cause rotational acceleration.
3. For a rigid body rotating about an axis, its rotational kinetic energy is equal to half the product of its moment of inertia and the square of its angular velocity. Similarly, the torque on a body produces angular acceleration that is inversely proportional to the body's moment of inertia.
Germain Henri Hess was a Swiss chemist born in 1802 who studied heat in chemical reactions and laid the foundation for thermochemistry. Hess's law states that the heat evolved or absorbed in a chemical reaction depends only on the chemical identities of the initial and final substances and is independent of the pathway between them. Thermochemistry deals with the thermal changes that accompany physical and chemical transformations and aims to determine energy absorption or emission and develop methods to calculate these thermal changes experimentally, such as determining heats of formation, transition, and reaction.

It then explains the different areas and curves in the phase diagram of water, including that the liquid-vapor, ice-vapor, and ice-liquid curves represent univariant systems while the areas represent bivariant systems. It also notes the unique properties of the ice-liquid curve and the triple point where ice, liquid water, and vapor coexist in equilibrium.
Colligative properties are properties of solutions that depend on the ratio of solute particles to solvent particles and not the chemical identity of the solute. The four main colligative properties are lowering of vapor pressure, elevation of boiling point, depression of freezing point, and osmotic pressure. These properties can be used to determine various solution characteristics like concentration but are more commonly used to understand phenomena like osmosis and melting ice on sidewalks for safety.
Colloids are mixtures where one substance is microscopically dispersed throughout another. They consist of two phases - a dispersed phase made of very tiny particles 1nm to 1um in size suspended in a continuous dispersion medium. Common examples are milk, fog, and blood. Colloids can be classified based on the physical state of the phases and the interactions between them. Preparation methods include mechanical grinding, electrical dispersion, peptization of precipitates, and condensation by changes in conditions. The interactions between colloidal particles, such as excluded volume repulsion, electrostatic forces, van der Waals forces, and steric effects influence colloid stability and properties.

Thermal analysis techniques can be used to characterize materials based on physical and chemical changes like melting point. Polymorphism, which is the ability to exist in multiple crystal structures, is important for pharmaceuticals as different polymorphs can have different properties.
The document discusses colligative properties, which are properties of solutions that depend on the number of solute particles present.

This document provides an introduction to sedimentology and stratigraphy. It discusses key concepts such as sedimentology focusing on accumulation under uniform conditions while stratigraphy records changes over time. Sedimentary rocks form through weathering, erosion, transport, deposition, lithification and diagenesis. Scientists study facies, depositional systems, and system tracts to interpret ancient environments. Stratigraphy reflects changes in the balance between space creation and filling in sedimentary basins. Correlating rock units across regions is important for stratigraphic research.
River erosion occurs through processes like abrasion and hydraulic action that wear away rock in the river bed and banks. This shapes the landscape, creating narrow V-shaped valleys through vertical erosion and lengthening rivers upstream through headward erosion. Lateral erosion widens the river channel and forms U-shaped valleys. River transportation involves moving eroded material downstream via traction, saltation, suspension, or solution based on the size and weight of the load.
Sedimentary bedding and structures provide information about depositional environments. Beds form layers and their thickness indicates the depositional process. Beds are often nested within each other. Bedding patterns include massive, tabular, wedge-shaped and lenticular beds. Bedforms like ripples, dunes and cross-bedding are produced by fluid flows and indicate flow conditions. Other structures provide evidence of channels, erosion and soft-sediment deformation. Together, these features preserve a record of Earth's surface history.
The document discusses river processes and landforms created by erosion, transportation, and deposition of sediment. Key points include:
- Rivers erode, transport, and deposit sediment through various processes including saltation, traction, suspension, and solution that create landforms such as potholes, rapids, waterfalls, deltas, and floodplains.
- The Hjulstrom curve shows the relationship between sediment size, erosion thresholds, and transportation/deposition based on water velocity.
- Meandering rivers create oxbow lakes through lateral erosion and cut-offs of meander loops over time.
Sediment is any particulate matter that can be transported by fluid flow and eventually deposited. There are four main categories of sediments based on size: gravel, sand, silt, and clay. Incipient motion, or the initial movement of sediment particles, is important to studying sediment transport and channel design. Two main approaches to modeling incipient motion are the shear stress approach and velocity approach. Shields developed a widely used diagram relating the critical shear stress needed to initiate motion to other dimensionless parameters like particle size, fluid properties, and sediment density. White's analysis also models critical shear stress as proportional to particle size. The velocity approach uses field surveys of permissible flow velocities before sediment starts moving in different channel materials.
The document discusses fluvial processes and landforms. It describes various types of erosion caused by water including surface erosion through splash and sheet erosion, and channel erosion through rills, gullies, and streams. It also discusses drainage basins and patterns, explaining how drainage patterns are influenced by geology and reflect the arrangement of river courses. Various landforms resulting from fluvial processes are also mentioned.
Stratigraphy is the study of temporal relationships in sedimentary rock layers and reflects changes in the balance between the rates of space production and filling. Stratigraphy records past geological events and adds a temporal dimension to sedimentology. It preserves details of major geologic events like mountain building, sea level changes, and climate fluctuations through principles such as superposition, original horizontality, lateral continuity, and crosscutting relationships.
This document discusses different sedimentary environments including terrestrial, marginal marine, and marine settings. Terrestrial environments include fluvial systems like braided rivers and meandering streams, alluvial fans, glacial deposits, lacustrine environments, and aeolian deposits in deserts. Marginal marine environments are located along the continental boundary and include beaches, barrier islands, lagoons, estuaries, and tidal flats. Marine environments discussed are coral reefs, continental shelf, continental slope, continental rise, and abyssal plain. Different sedimentary structures form in each environment providing clues to depositional conditions.

Thermodynamics is the branch of physics that deals with heat and other forms of energy. The first law of thermodynamics states that the total energy of a system remains constant, such that any increase in one form of energy (such as heat) results in an equal decrease in another form (such as work). The second law states that heat cannot spontaneously flow from a colder body to a hotter body without an input of work. The third law states that the entropy of a perfect crystal approaches zero as the temperature approaches absolute zero.

This document contains an astronomy homework assignment with multiple choice questions about the phases of the Moon and the scale of planetary orbits. It includes diagrams of the Moon at different positions in its orbit around Earth and asks the student to rank the Moon's appearance in terms of the illuminated area visible from Earth. The homework aims to test the student's understanding of the relative positions of Earth, the Sun and Moon and how this determines what lunar phase we see from Earth.
1) The document describes a ranking task that orders major events in the history of the universe from longest ago to most recent. It then provides context about the "cosmic calendar" that compresses the 14 billion year history of the universe into a single calendar year.
2) On the cosmic calendar, the Big Bang occurred at the start of the year on January 1st, approximately 14 billion years ago.
3) Earth formed in early September on the calendar, around 4.5 billion years ago.
The document discusses the moon's orbit around Earth and how it became synchronous. Originally, the moon rotated faster than it revolved around Earth, so different sides were visible from Earth over time. However, now the moon's rotation is synchronized exactly with its orbital period, so the same face always points towards Earth. We can only see the far side of the moon from photographs taken by spacecraft that have traveled to the other side.
This document provides an overview of celestial motions as seen from Earth. It defines key celestial concepts like the celestial sphere, zenith, horizon, and celestial poles. It describes how the apparent motions of celestial objects differ depending on an observer's latitude on Earth. The Sun's annual path against the background stars is called the ecliptic. The document aims to explain how humans developed an understanding of Earth's place in the universe by observing celestial motions.
This document does not contain any text to summarize. It appears to contain only repeated images without any context or explanation. The document consists solely of images without any accompanying text or context to understand the purpose or meaning of the images.
- Ancient astronomers initially constructed a model that placed Earth at the center of the universe, with all other objects orbiting around it. This was known as the geocentric model.
- Over time, as better instruments allowed for more detailed observations, this model could no longer explain all the observed facts about planetary motion.
- A new heliocentric model, placing the Sun at the center, was proposed and eventually accepted because it fit the experimental evidence better. This shows how scientific models evolve as new evidence is obtained through observation.
This document provides an overview of astronomy and the scientific method. It discusses:
1) Astronomy as the study of objects beyond Earth and how they interact, with the goal of organizing our understanding of the universe's history.
2) The scientific method as a process of making observations, developing hypotheses, and testing them through experiments or further observations. Hypotheses must be falsifiable to be scientific.
3) Scientific laws as consistent rules that describe natural phenomena, allowing our understanding to be applied universally throughout the universe. Laws are subject to revision with new evidence.
5Page43 how to classify stars parkslope heard from Annie.pdfDr Robert Craig PhD
This document discusses the spectral classification of stars. It explains that the advent of the spectroscope in the 1800s allowed astronomers to classify stars according to their spectral similarities. Originally there were 26 classes, but now there are 7 major classes - O, B, A, F, G, K, M - representing decreasing temperatures from 30,000 K to 3,000 K. Three problems are presented: 1) sorting 5 stellar spectra by closest match to standard spectra, 2) noting how spectral lines change with temperature, and 3) identifying which spectral types are missing from the sample.
This lab involves graphing the motion of people moving between positions. Students will record the time it takes a teacher or classmate to reach cones spaced 20 meters apart on a 100-meter track. They will create a position vs. time graph and calculate average velocities for each track segment. Students will then record each other performing different motions (walking, jogging, etc.) between the same positions and create their own position vs. time graphs to analyze and compare.
The document is a worksheet containing problems involving calculating average rates of change of functions over given intervals and finding equations of secant lines between two given points on functions. It includes 13 problems - the first 8 involve average rates of change, the next 4 involve secant lines, and the final problem is a critical thinking question about using two photos as evidence of speeding.
Johannes Kepler was a German mathematician and astronomer in the late 16th and early 17th centuries. He is most famous for discovering the three laws of planetary motion, which describe how planets move around the sun in elliptical orbits. Kepler also made important contributions to optics, geometry, and astronomy through his calculations of astronomical tables and discoveries in other areas of mathematics and science. He is considered a key figure in the scientific revolution.
Galileo Galilei's observations of Venus, Jupiter, and the Moon provided strong evidence supporting Copernicus' heliocentric model of the solar system. Galileo observed phases of Venus similar to Earth's Moon, proving that Venus orbits the Sun. He also discovered four moons orbiting Jupiter, showing that other celestial bodies can orbit something other than Earth.
This document provides an overview of topics to be covered in an astronomy course, including instructions and study questions. It discusses the celestial sphere model used by ancient Greeks to visualize the night sky, and how the apparent motions of celestial objects are caused by the rotation of Earth on its axis. Key points covered include the north and south celestial poles, celestial equator, constellations, and how the view of the night sky depends on the observer's latitude on Earth.
- Galileo Galilei was the first to use the telescope astronomically in 1609, observing sunspots on the Sun and features on the Moon like seas. His observations of Jupiter's moons provided evidence that bodies can orbit something other than Earth. His observations of Venus' phases provided evidence that Venus orbits the Sun.
- Kepler developed his three laws of planetary motion based on Brahe's astronomical measurements. His laws improved the Copernican model by showing planets orbit in ellipses rather than perfect circles.
This document provides materials for a lesson on how latitude affects the seasonal path of the sun. It includes an overview, objectives, preparation needed, and a procedure for an activity using hemisphere models. Students will study the sun's path above the Arctic Circle and compare it to locations at 42°N and the equator. They will explain how latitude impacts the duration of sunlight throughout the year. The activity aims to help students understand concepts like celestial motions, seasons, and how the sun's path varies with latitude.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
