Fire has been known to humans for nearly 500,000 years and was one of the earliest inventions, allowing early humans to cook food. Fire results from a chemical reaction that occurs when molecules meet and exchange electrons, transforming both molecules and releasing heat or light. Some of the earliest fires were stars in the sky.

Aztec mythology
The Aztecs worshipped many gods and deities that were central to their culture and mythology. Some of the major gods included Huitzilopochtli, the god of war and patron of Tenochtitlan; Tlaloc, the god of water, fertility, and rain; and Quetzalcoatl, the feathered serpent deity associated with knowledge and the arts. Other important gods were Tezcatlipoca, the god associated with night, hurricanes, and war; Tlazolteotl, the goddess of purification and childbirth; and Mictlantecuhtli, the god of the dead and king of the underworld. Each deity played a unique role in the
Thermal and electrical conductivity of metals
The document describes procedures to determine the heat capacity of a calorimeter, measure the heating of water due to ambient temperature, and estimate the thermal and electrical conductivity of copper and aluminum.
To measure thermal conductivity, the experiment determines the heat flow through metal rods using temperature measurements and Fourier's law of heat conduction. Electrical conductivity is estimated by recording current-voltage characteristics and calculating resistivity from Ohm's law. Results are found to be close to literature values. The Wiedemann-Franz law relating thermal and electrical conductivity is also discussed.
Holi sencillo
Holi is a Hindu festival celebrated in March that originated in north India. It celebrates the coming of spring and gives thanks for the harvested crops. People celebrate Holi by dancing, singing at parties, and throwing colored paint and water in the streets. Bonfires are also lit to mark the end of winter and the coming of warmth.

Telegraph—The Most Important Invention Of The 19th Century
The telegraph was the most important invention of the 19th century. Invented by Samuel Morse in 1832, it allowed messages to be conveyed electrically over long distances, replacing the need to physically deliver messages by horse. In 1844, Morse successfully transmitted the first message "What Hath God Wrought" from Baltimore to Washington D.C., demonstrating the telegraph's ability to communicate instantly across distances.

CISC vs RISC Processor Architecture
The document discusses the differences between CISC and RISC instruction set architectures. CISC aims to reduce storage usage and support compatibility, while making compilation easier and allowing complex assembly programming. RISC philosophy is to execute one instruction per clock cycle, use fixed-size instructions, only allow load/store instructions to access memory, and support high-level languages. While CISC was originally more common, the conclusion is that RISC provides more design simplicity, better pipelining, and is now preferable given cheaper memory.
Early humans ppt
Hominids first appeared around 3 million years ago in Africa. Early humans like Lucy were small hominids that walked upright unlike apes. Later groups like Homo habilis could make stone tools. Homo erectus controlled fire which allowed them to cook food and expand their range out of Africa. Neanderthals and Cro-Magnon man were skilled hunters and tool makers that populated Europe and beyond. Cro-Magnon man are notable for their cave paintings found in places like Lascaux, France, though the purpose of these paintings remains a mystery.

Fire ppt
Fire is caused by an oxidation reaction called combustion, which requires fuel, heat, oxygen, and a chain reaction. These four components make up the fire tetrahedron. To start a fire, the fuel and oxygen must be present and heated to their kindling temperatures to start the chain reaction. Once started, a fire can be extinguished by removing any part of the tetrahedron, or intensified by adding a catalyst to increase the combustion reaction rate. While fire can be dangerous, it also provides benefits like light, heat, and uses in certain ecosystems.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
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.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

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.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

For me the best invention is fire
- 1. For me The best invention is Fire For Diana Trujillo
- 2. History The Fire The fire was known to man almost 500,000 years before Christ. People have been using fire to cook their food for almost as long as there have been people on earth. African people invented on -purpose cooking fires probable about one million years ago.
- 3. What is fire? When two molecules meet under the right circumstances, they may exchange electrons in ways that change both molecules into new kinds of molecules. While they're doing that - reacting to each other - they may also release some electrical energy in the form of heat or ligth. This is what happens whenever there is a fire. The earliest fires were stars
