Radiation Oncology/Radiation Physics

 * Radiation is energy in movement. Electromagnetic radiation (EMR) refers to energy that travels in the form of waves. Another way of thinking about EMR is as a matterless bundle of energy called a photon. The photon is the “package” of energy that carries the energy through space. The other type of radiation is particulate, in which small particles (electrons, alpha particles) carry the energy. Particulate radiation can emanate from radioactive materials and linear accelerators. Particulate radiation is not effective for imaging due to low penetration of matter.

 * X-rays are produced from electric energy in the form of electrons flowing into the x-ray tube. Electrons are minute particles that possess a negative electric charge. The potential energy of an electron depends on its position in an electric circuit or on its energy level in an atom (electron shell). Within an electric circuit, electrons act as a conduit to transport energy. At the “source” (eg, electric socket), electrons possess a high potential energy that is then lost as the energy is converted into different forms when the electrons reach the “load” (eg, the x-ray tube).

 * All forms of energy used in medical imaging, with the exception of ultrasound, are a type of radiation. Radiation interacts with the human body in a way that creates information. The trajectory of radiation is straight until it interacts with matter. Matter both absorbs and scatters radiation. A fundamental principle of physics is that energy can neither be created nor destroyed, only converted from one form to another. When x-rays are used to image the human body, electric energy from a source is converted into x-rays and subsequently transformed into light, heat, and chemical energy.

 * The four main types of imaging modalities are x-rays (including computed tomography and fluoroscopy), ultrasound, magnetic resonance imaging, and nuclear medicine (including positron emission tomography [PET]).

Wikijunior:Biology/Science and theory of evolution

Science and theory of evolution
The aim of science is to understand the world better (knowledge) and to produce new technology (innovation). Scientists develop mental models (theories) and functional models (such as an engine). Then they test these models through thought and experimentation. Appropriate models are presented to the public. Scientists change these models and test them again. For scientists, models are not the truth. They are therefore always looking for improvements. Good theories are understandable and thoroughly tested.

Development of the theory of evolution
For centuries, scientists have repeatedly suspected that today's creatures had common ancestors. They knew that breeders of crops and livestock can change the characteristics of living beings. So, the pumpkin growers used only the seeds of the best pumpkins for the next seed. In some regions, growers propagated red gourds, in other regions green ones. This is how different shapes came about. However, the scientists could not explain how breeding without a breeder could work. Charles Darwin recognized that natural selection is possible without a breeder. For example, if the food is encased in a thick shell, a bird must be able to crack it to survive. A thick beak makes this possible. The problems in the habitat of living beings determines the goals. A narrow-pointed beak helps to capture insects. He realized this through observations on a trip to the Galapagos Islands.

Evolution as natural selection
The genes are located in the cells of living beings. The genes contain the building and operating instructions of the living being. These are made up of DNA.

DNA can be altered by naturally occurring radioactive radiation. This leads to changes in the offspring. As a result, children, such as Darwin finch chicks, have different characteristics. They are called variations.
 * Mutation

Some chicks die, others survive. Creatures that are better adapted to the environment have a better chance of surviving. Chicks with a feeding beak are more likely to survive.
 * Selection

The survivors can have children.
 * Propagation

Evolution as a scientific process
Evolution and scientific work are based on a comparable process:

Science: Scientists modify existing models. Evolution: Radiation changes DNA.
 * Mutation

Science: Scientists test the models in experiments. Evolution: The realities of nature are a severe test for all living beings.
 * Selection

Science: Through a publication, other scientists learn about the model. Evolution: Living beings have children.
 * Propagation

The theory of evolution describes a scientific knowledge and innovation process. Evolution produces innovations and insights

Direction and destination
A breeder strives for goals, the evolutionary process of nature does not. But the mechanism of evolution has one direction: best possible adaptation to the environment in order to survive. For example, being able to fly is very useful. Many innovations were needed before the physical and mental abilities were available for birds to fly and find their way back home after a migration.

Science and truth
In philosophy, there have been arguments about truth for centuries. Since each side was convinced that they had the (absolute) truth at their disposal, an agreement was impossible. Science has solved the problem: on the one hand, science dispenses with absolute statements. All statements are preliminary and can always be improved. On the other hand, scientists have developed methods to check the quality of models. Scientific statements are not true or untrue, but of high or low quality. That doesn't mean scientists aren't confident in their theories. However, good scientists are generally willing to revise their own convictions.

Is the theory of evolution a good theory?

 * The theory of evolution is understandable. It is clear that well-adapted creatures are more likely to survive.

 * The theory of evolution is logical. It is based on the laws of mathematics (statistics).

 * The theory of evolution is often tested. It has been verified by computer simulations, experiments and observations in nature.

 * The theory of evolution is helpful. It explains many properties of living things and processes in nature that would otherwise be incomprehensible.

The theory of evolution is a high-quality theory.

In particular, questions of speciation, the Cambrian Explosion and the origin of life are currently under discussion.

Digitial Media & Information in Society: The ClassWikiBook
This book is a collaborative book written by students enrolled in COM 216: Digital Media & Information in Society at SUNY Polytechnic Institute during the Fall 2023 semester, and the Wikibooks community.

The book will be structured around 12-15 topic coinciding with one of my classes (the "Monday" classes, probably). Each will be introduced by an essay/slides or slide show which will contain a reference list of sources referred to in the text/slides, and may be accompanied (after the class has occurred) by a video of a lecture/discussion of me presenting the essay/slide show (?)

Participants will be invited to add additional pages to each topic, branching off into either suggested threads (perhaps by links to future pages? [New Sandbox Page]...as well as to ask questions in the talk page, or of course to edit the main page as well (I guess? can that be turned off without violating the spirit of the Wikibook? Do I need to find another place to host this --> perhaps wikiversity?)

Tagalog/Verbs

Transitive verbs in Tagalog are conjugated according to the focus and tense of the sentence. A transitive verb can either be "subject-focused" or "object-focused." In English, the same conjugation is used for the following sentences: "I eat chicken" and "I eat the chicken." The verb in both sentences is "eat." In Tagalog, however, different conjugations of "eat" must be used. The first sentence in Tagalog would utilize a "subject-focused" verb and the second sentence an "object-focused" verb.

Example:

 * Kumakáin ako ng manók. (I eat chicken.)

 * Kinakáin ko ang manók. (I eat the chicken.)

In both sentences, "kumakain" and "kinakain" translates to the word "eat." The distinction between when to use a subject-focused verb and when to use an object-focused verb will develop over time.

Subject-focused verbs fall under two families: the "um" family or the "nag" family. Some root words of verbs whose subject-focused conjugation fall under the "um" family are the following.

 * káin (eat)
 * súlat (write)
 * sayáw (dance)
 * kantá (sing)
 * píla (to fall in line)
 * inóm (drink)
 * áyos (arrange)

Before enumerating verbs in the "nag" family, a discussion of tenses of the "um" verbs are in order. An example will be displayed here and then a discussion will follow thereafter.

Example:

 * PAST: Kumáin akó ng ságing. (I ate a banana.)
 * PRESENT: Kumakáin akó ng ságing. (I am eating / eat a banana.)
 * FUTURE: Kakáin akó ng ságing. (I will eat a banana.)

Discussion:

For subject-focus verb that fall under the "um" family and begin with a consonant, the rules are contained here. For the past tense, an "um" is inserted between the first consonant and vowel of the verb. So, the corresponding past tense for "kain" is "k-um-ain." (For this reason, "kain" falls under the "um" family.) Similarly, the past tense for "sulat" is "s-um-ulat."

A similar rule follows for the present tense of an "um" verb. Simply insert an "um" between the first consonant and vowel, but also immediately insert the first syllable before preceding with the rest of the word. So, the present tense of "kain" is "k-um-a-KA-in." Notice that the syllable "ka" has been inserted, since this is the first syllable that makes up the word "kain." The present tense of the verb "sulat" is "s-um-u-SU-lat." Furthermore, the present tense of "pila" is "p-um-i-Pɪ-la." Thus, the format of the present tense of this conjugation is:  Indeed, mastering Tagalog conjugation is no simple feat!

The future tense of subject-focus verbs under the "um" family that start with a consonant is simpler than their counterparts: reiterate the first syllable at the beggining of the word. Thus, the future tenses of the words "kain," "sulat," and "pila" are "KA-kain," "SU-sulat," and "PI-pila," respectively.

The rules for verbs that start with vowels are very similar but deserving of their own treatment. For the past tense, add "um" at the beginning of the word. Hence, the past tenses for "inom" and "ayos" are "um-inom" and "um-ayos." For the present tense, add "um" and then the first vowel (which is the first syllable) at the beginning of the word. Thus, the present tenses of "inom" and "ayos" are "um-i-inom" and "um-a-ayos." Finally, the future tense needs only a reiteration of the first vowel/syllable at the beginning of the word. So, the future tenses of "inom" and "ayos" are "i-inom" and "a-ayos."

Further Examples (using "sagót" and "ulán"):

 * Sumagót siyá. (He/she replied.)
 * Sumasagót siyá. (He/she is replying.)
 * Sasagót siyá. (He/she will reply.)
 * Umulán kanína. (It rained earlier.)
 * Umuulan ngayon. (It's raining now.)
 * Uulan bukas. (It will rain tomorrow.)

Supplementary mathematics/Law of total probability

The law of total probability, which is also known as Bayes' law of probability, is a rule of law in the field of statistics and probability that divides probability calculations into a separate, detailed and advanced part, that is, for example, you have no relative knowledge of the probability of the occurrence of an expression B, and for Finding the probability of an event B that we know, we can use to find the probability of the event B.

Multivariate Law of Total Probability
According to this pattern B1,..., Bn and an event called set A, the probability of event A can be calculated as a quantitative or weighted average in which the pattern B1,..., Bn plays a role to find the calculation of its occurrence. According to each occurrence in the partition pattern with the probability of the occurrence of partitioning in terms of quantity, this formula can be used:

$$ \Rho (\Alpha)=\Rho (\Alpha|\Beta _{1 })\Rho(\Beta _{1 })+.....+\Rho (\Alpha|\Beta _{n})\Rho(\Beta _{n})$$

The same idea can be applied and calculated for random vectors. In this way, it is possible to obtain a

For the marginal distribution, we pooled other variables from the joint distribution:

$$f (\Chi)\Chi _{1 }= \int\limits _{x_2 }^{ }  ...\int f \Chi_1 \Chi_2 (x_1, x_2)dx_2$$

The law of total probability is both an independent event and the probability of evil, and it is a general law for these two topics. From the definition of conditional probability, we know that

Chadian grilled fish is a popular dish in Chad known for its simplicity and flavorful taste. Fresh fish is marinated with local spices, then grilled to perfection, resulting in a delicious and aromatic meal. It is often served with a side of rice or millet for a complete and satisfying experience.

Ingredients

 * 2 tablespoons vegetable oil
 * 1 teaspoon ground paprika
 * 1 teaspoon ground ginger
 * 1 teaspoon ground garlic
 * 1 teaspoon ground cumin
 * 1 teaspoon ground coriander
 * Salt
 * Freshly ground black pepper, to taste
 * 2 whole fresh fish (such as tilapia or catfish), cleaned and scaled
 * Lemon wedges, for serving

Equipment

 * Grill
 * Mixing bowl
 * Basting brush
 * Tongs or spatula
 * Aluminum foil (optional)
 * Paper towels

Procedure

 * 1) Preheat your grill or barbecue to medium-high heat.
 * 2) In a mixing bowl, combine the vegetable oil, paprika, ginger, garlic, cumin, coriander, salt, and black pepper. Mix well to form a smooth marinade.
 * 3) Pat dry the fish with paper towels and place them on a plate or tray. Using a basting brush, generously coat both sides of the fish with the marinade. Make sure to cover the fish thoroughly for maximum flavor.
 * 4) If desired, you can let the fish marinate in the refrigerator for about 30 minutes to allow the flavors to penetrate. However, this step is optional, and you can proceed directly to grilling if you're short on time.
 * 5) Once the grill is heated, lightly oil the grates to prevent sticking. You use a folded paper towel soaked in vegetable oil and held with tongs to do so.
 * 6) Carefully place the marinated fish on the grill and close the lid. Cook for about 4–5 minutes per side, depending on the thickness of the fish, or until the flesh is opaque and easily flakes with a fork. While grilling, you can baste the fish with any remaining marinade using a basting brush for added flavor and moisture.
 * 7) Once the fish is cooked through and nicely charred, remove from the grill using tongs or a spatula. Be careful not to break the delicate flesh.
 * 8) Serve hot with lemon wedges on the side for squeezing over the fish. It pairs well with a side of rice or millet and can be accompanied by a fresh salad or steamed vegetables.

Notes, tips, and variations

 * Cooking times may vary depending on the size and thickness of the fish, as well as the heat of your grill. Adjust accordingly to ensure the fish is cooked to your desired doneness.
 * If desired, you can place the fish on a sheet of aluminum foil on the grill to prevent direct contact with the grates and facilitate easier flipping.

A-level Physics/Health Physics/Transport Phenomena

Transport phenomena refer to the processes by which mass, momentum, energy, and other physical quantities are transported through a medium. These phenomena are fundamental to understanding the behavior of fluids, gases, and solids in various engineering, scientific, and everyday situations. Transport phenomena are governed by principles of conservation laws and fluid mechanics and are crucial in fields such as chemical engineering, mechanical engineering, materials science, and environmental science.

The three main types of transport phenomena are:

 * Mass Transport: Mass transport involves the movement of substances from one location to another due to differences in concentration. This can occur through diffusion, where molecules move from areas of high concentration to areas of low concentration, as well as convection, where bulk fluid movement carries substances along with it. Examples include the diffusion of gases in the atmosphere and the transport of nutrients in biological systems.

 * Momentum Transport: Momentum transport relates to the movement of momentum (mass multiplied by velocity) within a fluid or solid. It is responsible for the flow of fluids, such as liquids and gases. Momentum transport is characterized by fluid flow patterns and is essential in understanding fluid dynamics, such as the flow of water in pipes or the motion of air around an aircraft wing.

 * Energy Transport: Energy transport involves the transfer of heat between regions of different temperatures. This can occur through conduction (direct transfer of heat within a solid), convection (heat transfer through a moving fluid), and radiation (transfer of heat through electromagnetic waves). Energy transport is crucial in understanding processes like heat exchange in industrial systems and the thermal behavior of materials.

Key concepts and aspects of transport phenomena include:

 * Transport Equations: Transport phenomena are described by mathematical equations, often based on principles of conservation of mass, momentum, and energy. These equations, such as the Navier-Stokes equations for fluid flow and the heat conduction equation for energy transfer, help model and predict the behavior of transport processes.

 * Boundary Conditions: The behavior of transport phenomena at boundaries (such as walls or interfaces between materials) is determined by boundary conditions. These conditions specify how quantities like mass, momentum, and energy are exchanged between the system and its surroundings.

 * Transport Coefficients: Transport phenomena are characterized by transport coefficients, such as diffusion coefficients, viscosity, and thermal conductivity. These coefficients represent the effectiveness of the medium in transporting different quantities and play a crucial role in the mathematical description of transport processes.

 * Dimensionless Numbers: Dimensionless numbers, such as the Reynolds number (characterizing fluid flow) and the Péclet number (characterizing mass transfer), provide insights into the relative importance of different transport mechanisms in a given system.

 * Transport in Biological Systems: Transport phenomena are also vital in biological systems, such as the transport of nutrients and gases within cells and the circulation of blood in the human body.

Understanding transport phenomena is essential for designing efficient industrial processes, optimizing material properties, predicting fluid behavior, and solving a wide range of engineering and scientific problems involving the movement of mass, momentum, and energy.

Mass Transport
Mass transport, also known as mass transfer, refers to the movement of substances (particles, molecules, or ions) from one location to another within a medium, such as a gas or a liquid. Mass transport can occur due to concentration gradients, pressure differences, or other driving forces. This phenomenon is important in various scientific and engineering disciplines, including chemistry, biology, environmental science, and chemical engineering.

There are two main types of mass transport: diffusion and convection.

 * Diffusion: Diffusion is the process by which particles move from an area of high concentration to an area of low concentration, driven by the random thermal motion of particles. This movement aims to achieve a state of equilibrium, where concentrations are uniform throughout the medium. Diffusion is a passive process that occurs even in the absence of external forces.

 * Convection: Convection involves the bulk movement of fluid, which carries particles along with it. It can be further categorized into natural convection (caused by density differences in a fluid due to temperature variations) and forced convection (induced by external forces, such as fans or pumps). Convection enhances mass transport by introducing fluid motion that helps distribute particles more quickly and efficiently.

Applications of mass transport include:

 * Chemical Reactions: In chemical reactions, reactants need to come into contact with each other to react. Mass transport ensures that reactants are transported to the reaction sites, increasing the chances of reaction.

 * Cellular Processes: In biological systems, mass transport plays a role in processes like nutrient absorption in cells, waste removal, and gas exchange.

 * Membrane Separation: Techniques like dialysis, reverse osmosis, and membrane filtration rely on mass transport to separate different substances based on their size and concentration gradients.

 * Environmental Remediation: Mass transport is crucial in processes like groundwater remediation, where contaminants are transported through soil and water by diffusion and advection.

 * Heat and Mass Transfer: In heat exchangers, mass transport is involved in the transfer of heat as well as the exchange of substances between fluid streams.

 * Food Industry: Mass transport is important in processes such as drying, where moisture is removed from food products to extend shelf life.

 * Pharmaceuticals: Mass transport is considered in drug delivery systems to ensure that drugs are released at the intended rate and location within the body.

 * Pollutant Dispersion: Understanding mass transport helps in modeling the dispersion of pollutants in air and water, aiding in environmental impact assessments.

 * Material Processing: In metallurgy and materials science, mass transport affects processes like diffusion bonding, where atoms migrate across the material interface to form strong bonds.

 * Chemical Engineering: Mass transport principles are central to designing reactors, separators, and other equipment in chemical engineering processes.

Understanding mass transport is essential for optimizing processes, predicting behavior in various systems, and designing efficient systems in numerous scientific and engineering applications.

Momentum Transport
Momentum transport, also known as momentum transfer or fluid momentum transport, refers to the movement or transfer of momentum within a fluid (liquid or gas). Momentum is a vector quantity that represents the motion of an object and is defined as the product of mass and velocity. In fluid dynamics, momentum transport plays a crucial role in understanding how fluids flow, interact with surfaces, and transfer forces.

There are several key concepts and mechanisms associated with momentum transport:

 * Viscosity: Viscosity is a property of fluids that describes their resistance to shear or deformation. When a fluid flows, layers of the fluid may slide over each other. Viscosity causes internal friction and resists this relative motion, leading to momentum transfer. High-viscosity fluids, like honey, resist flow more than low-viscosity fluids, like water.

 * Navier-Stokes Equations: These partial differential equations describe the behavior of fluid flow, including the conservation of momentum. Solving the Navier-Stokes equations for a given fluid flow scenario provides insights into how momentum is transferred within the fluid.

 * Reynolds Number: The Reynolds number is a dimensionless quantity that characterizes the relative importance of inertial forces to viscous forces in a fluid flow. It helps predict flow patterns, such as laminar or turbulent flow, and influences momentum transport.

 * Boundary Layers: When a fluid flows over a surface, a thin layer called the boundary layer forms near the surface due to viscosity. This layer experiences velocity changes, and momentum transport within the boundary layer affects the overall fluid motion.

 * Impulse and Momentum Change: The change in momentum of a fluid element is related to the force acting on it over time. This concept is known as impulse and momentum change, and it's crucial in understanding how forces influence fluid motion.

 * Bernoulli's Principle: Bernoulli's principle relates the pressure, velocity, and elevation of a fluid in a steady flow. It illustrates the balance between pressure and kinetic energy and helps explain the conservation of momentum in fluid systems.

Applications of momentum transport include:

 * Fluid Flow Analysis: Engineers and scientists use momentum transport principles to analyze fluid flow in pipes, channels, and various industrial systems.

 * Aerodynamics: Momentum transport is central to the study of air and gas flow over aircraft wings, vehicles, and other structures.

 * Hydrodynamics: In the study of water flow in rivers, oceans, and water distribution systems, understanding momentum transport helps predict water movement and erosion patterns.

 * Heat Exchangers: In heat exchangers, fluids exchange thermal energy while also exchanging momentum. Understanding momentum transport helps optimize the efficiency of heat transfer.

 * Wind and Water Turbines: The design and efficiency of wind turbines and water turbines depend on momentum transport principles, as they involve the conversion of fluid kinetic energy into mechanical energy.

 * Blood Flow: In medical applications, momentum transport principles are applied to understand blood flow patterns in arteries and veins, aiding in diagnosing cardiovascular conditions.

Heat Transfer
Heat transfer is the process of energy exchange between objects or regions due to temperature differences. It occurs in various ways, including conduction, convection, and radiation. Heat transfer is a fundamental concept in physics and engineering, as it influences a wide range of natural and technological processes.

Here are the three primary modes of heat transfer:

 * Conduction: Conduction is the transfer of heat through a solid material without any movement of the material itself. In this process, heat energy is transferred from higher-temperature regions to lower-temperature regions within the material. This transfer occurs due to the vibration and collision of particles (atoms or molecules) within the material. Metals, for example, are good conductors of heat due to their high thermal conductivity.

 * Convection: Convection is the transfer of heat through a fluid (liquid or gas) due to the movement of the fluid itself. This movement can be caused by differences in density and temperature. When a fluid is heated, it becomes less dense and rises, while cooler fluid sinks. This creates a circulation pattern known as a convection current. Natural convection occurs without external forces, while forced convection involves the use of external means, such as fans or pumps, to enhance fluid movement.

 * Radiation: Radiation is the transfer of heat through electromagnetic waves, such as infrared radiation. Unlike conduction and convection, radiation can occur in a vacuum and does not require a medium to propagate. All objects emit thermal radiation, with the amount and wavelength of radiation emitted depending on their temperature. This mode of heat transfer is responsible for the transfer of heat from the Sun to Earth and for the emission of heat from various objects.

Heat transfer plays a crucial role in various applications, including:

 * Thermal Comfort and HVAC Systems: Understanding heat transfer is essential for designing heating, ventilation, and air conditioning (HVAC) systems to maintain comfortable indoor environments.

 * Energy Generation: Heat transfer is central to energy generation processes, including power plants that use steam turbines and heat engines.

Radiative transfer refers to the process by which electromagnetic radiation (such as light) interacts with and is transmitted through a medium, such as gases, liquids, or solids. It is a fundamental concept in various scientific fields, including physics, astronomy, atmospheric science, and remote sensing. The concept of radiative transfer is used to describe how radiation propagates, scatters, absorbs, and is emitted by materials in different environments.

Here are some key points related to radiative transfer:

 * Absorption: When electromagnetic radiation passes through a medium, it can be absorbed by the atoms, molecules, or particles within that medium. The absorbed energy can lead to changes in the energy state of the absorbing material.

 * Scattering: Scattering occurs when radiation interacts with particles or molecules in the medium, changing the direction of its propagation. Depending on the size of the scattering particles relative to the wavelength of the radiation, different types of scattering, such as Rayleigh or Mie scattering, can occur.

 * Emission: Emission involves the release of electromagnetic radiation from a material. When a material is heated or excited, it may emit radiation across a range of wavelengths. This process is fundamental to understanding thermal radiation, such as blackbody radiation.

 * Reflection and Transmission: Radiation can be reflected or transmitted when it encounters the surface of a material. Reflection involves the bouncing of radiation off the surface, while transmission involves the passage of radiation through the material.

Radiative Transfer Equation: The radiative transfer equation is a mathematical framework used to describe the interactions of radiation within a medium. It considers parameters such as absorption, scattering, emission, and the geometry of the medium. Solving this equation for specific scenarios provides insights into how radiation behaves in various environments.
