Module Nine - Space Race - Arms Race
The Space Race and nuclear arms race were heated competitions between the United States and Soviet Union during the Cold War. The Space Race began with the Soviet launch of Sputnik and involved satellites, manned spaceflight, and landing on the moon. The US and USSR engaged in a massive nuclear arms buildup, developing more powerful bombs like hydrogen bombs, and delivery systems like ICBMs that could span continents, in a quest to achieve military supremacy. Both sides developed large nuclear arsenals and second-strike capabilities, resulting in a balance of terror known as Mutually Assured Destruction that prevented direct military conflict but fueled a costly arms buildup throughout the Cold War.

Nuclear arms race:space race
The document discusses several key aspects of the nuclear arms race between the US and Soviet Union during the Cold War. It begins with the US dropping atomic bombs on Hiroshima and Nagasaki in 1945. The Soviets then developed their own atomic bomb in 1949, marking the start of the arms race. Both sides developed powerful new weapons like hydrogen bombs and intercontinental ballistic missiles capable of delivering nuclear payloads globally. Tensions escalated during events like the US announcing a policy of massive retaliation and the Cuban Missile Crisis, bringing the two superpowers closest to nuclear war.
Rutherfordium
Rutherfordium is an artificially produced radioactive transuranic element with atomic number 104. In 1964, Soviet scientists at the Joint Institute for Nuclear Research in Russia discovered element 104 and named it kurchatovium after Igor Kurchatov. In 1969, American researchers at the University of California, Berkeley identified different isotopes of the element and proposed the name rutherfordium in honor of Ernest Rutherford.
Scientific events 1945 1968
In 1953, Francis Crick and James Watson discovered the double-helix structure of DNA, publishing their findings in Nature. In 1955, Louis Essen invented the first accurate atomic clock based on the caesium-133 atom. In 1957, the Soviet Union launched Sputnik 1, the first artificial satellite, demonstrating their capability to launch objects into space.

Space race by alaa
The document discusses the Space Race between the US and USSR during the Cold War from 1957-1975. The two superpowers competed to achieve firsts in space exploration, such as launching satellites, sending humans into space, and landing on the Moon, which were seen as demonstrations of technological and ideological superiority. The Space Race began with the Soviet Union's launch of Sputnik 1 in 1957 and concluded with the US landing astronauts on the Moon in 1969, achieving President Kennedy's goal. The Space Race had long-term effects on education in the US by inspiring greater emphasis on STEM subjects in schools.
Activities
The document provides instructions for group activities related to medieval England. Students will: 1) research social life, kings, battles and Saint Thomas Beckett's connection to Canterbury from a historic period; 2) listen to Geoffrey Chaucer's biography and create a timeline of important life events; 3) watch videos of stories from The Canterbury Tales, choose one, and summarize the characters, plot and moral lesson.
Apollo xiii 2014
Apollo 13 was a 1970 Apollo space mission to the moon that suffered a critical failure en route. The three astronauts aboard - James Lovell, Jack Swigert, and Fred Haise - worked with mission control to return safely after an oxygen tank exploded, endangering the spacecraft and crew's survival. The explosion forced the crew to abort their lunar landing and return to Earth earlier than planned, making emergency repairs and using the lunar module as a "lifeboat" to keep the command module's systems functioning well enough for reentry.

The nuclear arms race by vibeesh
The document discusses the development of nuclear weapons by the United States and Russia during the Cold War. It notes that the US was the first to develop nuclear weapons and used them against Japan, shocking the world. Russia then began developing its own nuclear weapons to compete with the US in the arms race. Both countries massively increased their nuclear stockpiles throughout the 1950s and developed more powerful weapons like the hydrogen bomb. This arms buildup continued into the 1960s and led to a theory of mutual assured destruction if either country initiated a nuclear attack.
Space Race Presentation With Works Cited[1]
The document discusses the early history of rocketry pioneers Konstantin Tsiolkovsky, Robert Goddard, and Hermann Oberth, who conducted experiments in the late 19th and early 20th centuries. It then covers the Space Race between the US and USSR during the Cold War, which began with the Soviet Union's launch of Sputnik in 1957 and ended with the US landing on the moon in 1969. The Space Race accelerated technological advances and helped launch the modern space age, but also increased fears and paranoia that contributed to UFO conspiracy theories and sci-fi culture.

Stephen Hawking was a renowned theoretical physicist and applied mathematician known for his contributions to general relativity and quantum gravity. Some of his many honors and awards included the Eddington Medal, Albert Einstein Medal, and Presidential Medal of Freedom. He warned of existential risks to humanity from threats like nuclear war or engineered pandemics and advocated for human space exploration. Al Capone was a notorious American gangster and crime boss during the Prohibition era in the 1920s who controlled organized crime in Chicago. Though infamous, he believed he was only supplying a demand and that fear was key to his criminal organization's power.
R. Hechter: Chasing Aurora: Using authentic context for STEM
This document outlines plans to develop a STEM curriculum focused on studying the aurora borealis. It discusses using the aurora as an authentic context to teach science, technology, engineering, art and math concepts. The curriculum would involve students learning fundamentals at home and then communicating in real-time with researchers in Manitoba, who are working to capture photos and study the aurora. Future plans include revising the companion curriculum, partnering with schools worldwide on an "overhead view" experiment, and visiting Churchill multiple times per year to continue developing the project.
Chadwick
James Chadwick was a British physicist born in 1891 who is known for discovering the neutron. He received several honors for his work, including the Nobel Prize in Physics in 1935. Chadwick served in World War I and was a prisoner of war. He also participated in the Manhattan Project during World War II. Chadwick's model of the atom focused on neutrons, differing from Niels Bohr's model which depicted electrons in rings. Both models showed the structure of the atom but represented it differently.

Two burial chambers located within 25 meters of each other were found in the mound during excavations in 1847. Artifacts from the Early Christian period and animal bones were uncovered. The mound contains two tombs facing west surrounded by an estimated 115 surrounding stones. One tomb is smaller with a short passageway and circular chamber. The larger tomb's passageway divides into a cruciform chamber with three side recesses and annexes containing additional chambers.
Unexplained artifacts
Mysterious metal spheres measuring about an inch in diameter have been found in South Africa in rock dated to 2.8 billion years old, and some are etched with three parallel grooves. Fossils that seem out of place have also been found, including a human handprint in limestone estimated at 110 million years old and a possible human footprint from 300-600 million years ago. In 1938 in China, an expedition discovered a cave containing hundreds of stone disks approximately nine inches in diameter with a central circle and spiral groove etched with tiny hieroglyphs telling a story about a crashed spacecraft and its pilots called the Dropa.

TUNGUSKA EVENT
The document summarizes a scientific report on the Tunguska event of 1908, in which an extraterrestrial object exploded in the atmosphere over Siberia. Witnesses observed a fireball and heard a loud bang, which felled around 80 million trees over 2,150 square kilometers. Though no crater was found, evidence points to an asteroid or comet exploding 5-10 kilometers above the surface. The event generated energy equivalent to 185 Hiroshima bombs but caused no casualties due to the remote location. Scientists still debate whether it was an asteroid or comet and investigate the risks of future impacts.
The wilkes land crater
The Wilkes Land Crater is the largest impact crater ever discovered on Earth, located in East Antarctica. It was formed approximately 250 million years ago by a meteorite that was 50 kilometers wide. At 483 kilometers wide, it is larger and older than the Chicxulub crater associated with the extinction of the dinosaurs. The Wilkes Land Crater was discovered in 2006 using NASA gravity radar and would have caused massive damage when it impacted due to its enormous size. It may have contributed to the largest mass extinction event on Earth, the Great Dying in the Permian period.
Tunguska Event by group6
The document summarizes theories about the cause of the 1908 Tunguska event in Siberia, in which an explosion leveled 800 square miles of forest. Early expeditions in the 1920s found no crater or meteorite fragments, but subsequent hypotheses proposed a meteorite impact. Later studies in the 1990s suggested an exploding alien spacecraft caused the blast. In 2007, Italian researchers claimed to have discovered an impact crater under Lake Cheko near the explosion site.
The earth’s interior
This document provides an overview of the internal structure of the Earth. It describes the three main layers - crust, mantle, and core. The crust is the outermost layer and is divided into continental and oceanic crust. Beneath the crust is the mantle, which makes up most of the Earth's volume. The core is at the center and has a solid inner core and liquid outer core. Seismic waves and magnetic reversals provide evidence about the composition and movement of materials in the Earth's interior.
Psyche 16 Asteroid Research of NASA
Psyche 16 is a large metallic asteroid that orbits between Mars and Jupiter. It is composed primarily of iron and nickel, unlike most other asteroids which contain silicate minerals. Due to its high metal content, Psyche 16 is estimated to have a value of $700 quintillion. NASA is planning a mission to explore Psyche 16 which could provide insights into the early formation of planets in the solar system, as Psyche 16 may be the exposed core of an early planet. The Psyche mission could launch in 2022 and arrive at the asteroid in 2026 to study it from orbit for 21 months.

Harry Coumnas’ Description about the Eclipse of Ash Clouds
Thirty years ago, the people of Russia thought that they were witnessing an eclipse and the strange darkness was just the beginning. Many heavy storms in the area opened graves and even boats navigated the streets, where floods destroyed many villages. Within a few years, it entered into a mini Ice Age. Harry Coumnas, a famous geologist in Russia found out that this disruptive weather came from a historic volcanic eruption. Harry Coumnas told that it was so epic that the ash clouds blanketed the world and even blocked the sun’s warmth.
Australia's ancient past
There are two main sources that can provide information about Australia's ancient past: oral accounts from Aboriginal and Torres Strait Islander peoples, and archaeological evidence. Oral accounts include stories passed down for generations about origins, customs, and laws.

Enceladus has jets of water vapor and organic molecules erupting from its
Meteorites
There are three basic types of meteorites: stony, iron, and stony-iron. Stony meteorites are the most common type, making up 90% of meteorite falls. The value of a meteorite depends on its chemical composition and abundance - rare meteorites from Mars or the Moon can be worth $2,500-$3,000 per gram. Meteorite hunters search known strewn fields using metal detectors and magnets to locate scattered fragments, sometimes following eyewitness accounts of meteorite falls.
How far is thr road to the moon
This document summarizes the history of space exploration, beginning with early experiments with rockets and satellites in the 20th century. It discusses key events like the launch of Sputnik 1, the founding of NASA, and the first missions that sent animals (dogs) into space to test the viability of life support systems before human spaceflight. The overall goal of space exploration is discussed - to answer fundamental questions about what exists in space and how resources there could benefit life on Earth, while better understanding our planet and solar system through observation and research beyond our atmosphere.
12. Meteoroids and Comets (Trexia).pptx
Meteoroids are small rocky bodies that travel through space. When they enter Earth's atmosphere, they are called meteors and if they survive entry and hit the ground, they are called meteorites. Meteoroids come from asteroids and comets. Meteors are commonly called shooting stars. Meteor showers occur when Earth passes through streams of debris left by comets. Comets originate from the Kuiper Belt beyond Neptune or farther out in the Oort Cloud, and are composed of ice and dust. When comets approach the sun, their tails always point away from the sun due to the pressure of the solar wind.
The Gameplay called Moon Voyage and the truth behind it
The document discusses skepticism around the moon landings and proposes an alternative theory. It questions how the astronauts could have survived the conditions on the moon given its lack of atmosphere and extreme temperatures. It also raises doubts about how the landings were filmed without advanced satellites. The author believes the moon voyages have coincided with conflicts harming Muslim populations, suggesting they may have been orchestrated to provoke such events.
Asteroids
Asteroids are small rocky or metallic bodies that orbit the sun and range in size from meters to over 500 km wide. They are found predominantly in the main asteroid belt between Mars and Jupiter. Ceres is the largest asteroid at 940 km in diameter. Asteroids are classified according to their composition, with C-type asteroids being the most common at 75% and consisting of carbon and dust. It is believed that an asteroid impact was responsible for the extinction of dinosaurs 65 million years ago.

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.
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.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Nucleophilic Addition of carbonyl compounds.pptx
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.
Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
