Acausal Sope-Area Relations: Drainage Basins on Random Topography
This document discusses slope-area relations on random topography. It begins by introducing the concept of slope-area relations and noting they are conventionally thought to arise from fluvial erosion. It then presents analytical results showing that for Gaussian random surfaces, plan curvature correlates inversely with slope. Specifically, gentle slopes typically have high convergence and steep slopes have low convergence. This geometric correlation between plan curvature and slope results in a slope-area relation on random surfaces without erosion. The document concludes that slope-area relations can arise from how rivers choose their paths on random topography, not just erosion, and that Gaussian surfaces provide a model for this behavior.
Pc chapter 7-3
The theory of plate tectonics states that the Earth's crust is divided into plates that move over the mantle. There are three types of boundaries where plates meet: divergent boundaries where plates pull apart and new crust is formed; convergent boundaries where plates push together resulting in subduction zones, volcanoes, or mountain building; and transform boundaries where plates slide past one another causing earthquakes. Convection currents in the mantle are believed to drive the motion of tectonic plates.
Slope stability
1. Soil slopes become unstable when the shear stress along a failure plane exceeds the shear strength of the soil. This can occur along distinct layers within a slope.
2. One defined failure plane is the interface between a sloping soil layer and an underlying impermeable layer. The overlying soil is prone to sliding failure along this interface.
3. Stability charts can be used to analyze slope failures in cohesive soils, accounting for soil cohesion, internal friction angle, and slope geometry.

The document discusses the effects of climate change and global warming, including the melting of glaciers causing sea level rise and changes to coastal environments. Pictures show the retreat of glaciers on Mount Hood in Oregon between 1984 and 2002 as an example. A graph shows measured changes in global sea level over time. Links are provided about the effects of sea level rise, melting glaciers, and earthquakes as examples of how the Earth's surface can be modified by natural forces.
Lateral earth pressure
This document discusses lateral earth pressure and provides details on Rankine's theory and graphical methods for determining active and passive earth pressures. It explains that lateral earth pressure is exerted by soil on retaining structures and depends on whether the structure is stationary or moving towards/away from the soil mass. Rankine's theory assumes dry, homogeneous soil and a vertical wall. Rebhann and Culmann's graphical methods can be used to locate the failure plane and determine the magnitude and direction of lateral earth pressures based on the soil's friction angle and the structure's orientation.

Topography let s_take_a_hike_ (1)
A topographic map uses contour lines to show elevation and terrain features. The document explains what contour lines are and how they represent points of equal elevation. It then uses examples of hiking up and down a hill to demonstrate how to read elevations on a topographic map using contour lines. Finally, it provides a topographic map example and questions to test the reader's understanding of reading elevations from the contour lines.
Notes chemical equations
The document discusses balancing chemical equations by following the law of conservation of mass. It explains that a chemical equation uses symbols to represent a chemical reaction, with reactants on the left side of the yield sign and products on the right. For the equation to be balanced, the number of atoms of each element must be equal on both sides after coefficients are added. This ensures the mass is also conserved, as required by the law of conservation of mass. An example demonstrates balancing the equation for the combustion of propane by adding coefficients to match the number of carbon, hydrogen and oxygen atoms on each side.
The periodic table
The periodic table arranges elements from left to right based on increasing atomic number. Elements in the same column or group have similar properties, while properties gradually change across each period or row from left to right as atoms get smaller but more massive. The periodic table was created by Russian chemist Dmitri Mendeleev and represents each element with a chemical symbol and atomic number to classify its identity and properties.
Are you rotating or revolving
The document discusses the difference between rotation and revolution as it relates to Earth and other celestial bodies. It explains that rotation is turning on an axis, like a figure skater or basketball, while revolution is moving around another object in an orbit, like a tetherball around a pole or Earth around the Sun. The document aims to teach students about how Earth's rotation causes day and night and its revolution causes changes in seasons, as outlined in several Texas Essential Knowledge and Skills science standards.
Physical vs chemical changes notes
Physical changes alter a substance's appearance or structure but do not change its chemical composition. Examples include melting, freezing, and dissolving. Chemical changes form new substances with different properties through rearrangement of atoms, as seen in rusting, burning, and cooking. Evidence of a chemical change may include production of a gas, change in temperature, formation of a precipitate, or color change. A chemical change can be confirmed if the products of a chemical equation are different from the reactants.
Topo and satellite views notes
Topographic maps and satellite views are used to interpret landforms and predict how erosion may change them over time. Cartographers create topographic maps using data from aerial photos and satellites, which photograph the Earth's surface. Topographic maps model the three-dimensional landscape using contour lines that connect points of equal elevation, with closer lines indicating steeper slopes. Contour lines never cross and show the shape and elevation of an area.
Classification of stars notes w questions
In the early 20th century, astronomers Henry Russell and Ejnar Hertzsprung constructed a diagram called the Hertzsprung-Russell diagram (HR diagram) that compares the luminosity and surface temperature of stars. The HR diagram serves as an important tool for astronomers to classify stars and reveal relationships between stars by showing them at different ages and stages of evolution. It classifies stars into groups based on their surface temperatures from hottest, blue-white group O stars to coolest, red group M stars.
Plate tectonics notes
Plate tectonics describes how the Earth's crust is divided into tectonic plates that move relative to each other. The movement of plates is caused by convection currents in the asthenosphere and results in major geological events at plate boundaries like earthquakes, volcanoes, and mountain building. There are three types of plate boundaries - divergent where plates move apart, transform where they slide past each other, and convergent where they push together.
Balancing chemical equations notes
This document discusses balancing chemical equations. It explains that a chemical equation uses symbols and formulas to represent a chemical reaction and must obey the law of conservation of mass. This law states that the number and type of atoms on the reactants side must equal the number and type on the products side. The document shows an example of an unbalanced equation and uses coefficients to balance the atoms, resulting in an equation that follows the law of conservation of mass.
Physical vs chemical changes notes
Physical changes alter a substance's appearance or structure but do not change its chemical composition. Examples include melting, freezing, and dissolving. Chemical changes form new substances with different chemical compositions through rearrangement of atoms, as evidenced by production of a gas, change in temperature, formation of a precipitate, or color change. Common chemical changes are rusting, tarnishing, burning, cooking, and digesting.
Galaxies nebulae stars notes
Within galaxies, star forming regions called nebulae contain clouds of dust, hydrogen and helium gases. Stars sometimes form within these nebulae as the gases and dust collapse under their own gravity. A nebula with protostars, or young stars that are still forming, is shown in the diagram. The document then goes on to describe the life cycle of stars like our Sun and the changes it will undergo as it evolves and eventually dies in approximately 5 billion years.
Notes chemical formulas
The document discusses chemical formulas and their use in representing substances. It explains that chemical formulas use symbols to show the elements present in a compound and subscripts to indicate the number of atoms if more than one atom is present. Coefficients are also used to show the number of molecules if more than one molecule makes up the total substance. Examples of common chemical formulas are provided along with the total number of atoms and molecules they represent.

Millions of humans live near the major tectonic plate boundaries. The potential dangers of living on or near a plate boundary include earthquakes, volcanoes, and tsunamis. However, these natural hazards do little to discourage people f.
Review 8 landscapes_sc
This document contains a summary of key landscape regions in New York State and questions about the characteristics and formation of these regions. It discusses regions such as the Taconic Mountains, Adirondack Mountains, Hudson-Mohawk Lowlands, and others. The questions cover topics like the bedrock, elevation, and erosional features of different plateau, mountain, and lowland areas. Climate and glacial activity are identified as important factors that shaped the geology and terrain over time.
تکتونیک
The document discusses plate tectonics and describes the different types of plate boundaries including divergent boundaries, convergent boundaries, and transform boundaries. It provides examples of specific landforms created by different boundary types, such as rift valleys from divergent continental boundaries and island arcs and trenches from convergent oceanic boundaries. The driving force behind plate movements is convection currents in the mantle.
Earthquakes final
The document discusses dynamics of the Earth including evidence of crustal motions such as uplift and erosion that create mountains and sedimentary layers. It explains how marine fossils found in high elevations provide evidence of crustal movement over time. Earthquakes are described as being caused by the movement of tectonic plates and release of stress that builds in rocks, sending seismic waves that can be used to locate an earthquake's epicenter. The layers of the Earth are also outlined, with the crust varying in thickness and composition in different regions.

The document discusses key concepts about atoms including:
1) Atoms are made up of protons, neutrons, and electrons with protons being positively charged and electrons being negatively charged.
2) The periodic table organizes elements based on their number of protons (atomic number) and mass number.
3) Chemical equations show reactants yielding products while conserving mass according to the law of conservation of mass.
How astro gather info space
Astronomers gather information about space by detecting and analyzing electromagnetic radiation emitted or transmitted from celestial objects. Different types of electromagnetic radiation, including radio waves, visible light, and others, provide data about distances, properties, compositions and motions when collected by telescopes and studied. Spectroscopy techniques separate light into spectra that reveal characteristics of astronomical sources like temperature, density, and chemical makeup through unique spectral patterns.
Atom notesshort
The document discusses the structure of atoms. It explains that atoms are made up of a nucleus containing protons and neutrons, surrounded by electrons. The number of protons determines the element's identity and the number of neutrons plus protons determines the atom's mass number. Electrons occupy different energy levels surrounding the nucleus. The number of valence electrons in the outermost shell determines an element's chemical properties and reactivity.

The document discusses the structure of atoms. It explains that atoms are made up of a nucleus containing protons and neutrons, surrounded by electrons. The number of protons determines the element's identity and the number of neutrons is used to calculate atomic mass. Electrons occupy different energy levels surrounding the nucleus. Valence electrons, in the outermost shell, determine an element's chemical properties and reactivity.
Atom notes
- Atoms are made up of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit in energy levels around the nucleus.
- The number of protons determines the element and is equal to its atomic number. The total number of protons and neutrons determines the atomic mass of an element.
- Electrons occupy different energy levels based on their distance from the nucleus, with the first level holding up to 2 electrons and subsequent levels holding more. Valence electrons in the outermost level determine an element's reactivity.
Notes scientific investigation
Scientific investigations involve asking questions and collecting qualitative and quantitative data. There are three main types of investigations: descriptive investigations involve asking questions without hypotheses; comparative investigations compare objects or events under different conditions and include hypotheses; experimental investigations test manipulated variables and include hypotheses, controls, and independent and dependent variables.

Equivariant neural networks and representation theory
Or: Beyond linear.
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.

The cost of acquiring information by natural selection
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:

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
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.

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.
