...Unit 16-Astronomy and Space Science B2 Electromagnetic Spectrum Telescopes A telescope uses a curved lens or mirror to collect light from distant objects and to focus that light to an image. A bigger objective lens or mirror collects more light therefore it creates a brighter and much sharper image. The focused image, which is formed by the objective lens of a telescope, is magnified by a smaller second lens called an eyepiece. As visual observers, we look into the eyepiece to see the bright magnified image from the objective. But an eyepiece used with a small lens or mirror simply magnifies a dim and fuzzy image. Reflecting Telescopes When light hits a surface that it can't travel through, it bounces back. If the surface is smooth, like...

...some key concepts were hard to understand, Thus this version was released. Its aim is to make the difficult scientific theory's more accessible to the general public. The book is an attempt to explain everything we know, or think we know about the universe and cosmology. The first few chapters of the book are aimed at explaining the basics of physics and how it has progressed over time, It goes on to talk about Newton's laws and explain what a scientific theory is. This is a great move by the authors because it helps to explain the complex material by first going through the foundations of physics, this in turn makes the book far more accessible to the public . This is perfect as the book is aimed at ordinary people with an interest in science. The language used in the book is fairly technical but has been simplified to make the book easier to understand, this has been done well because they haven't made it patronising. The style of explanation really opens up the theory's to everyone, for example they have used cleaver metaphors such as ping pong balls and trains, this is topped off with interesting and sometimes humours pictures to help you visualise what is being described, this also helps to break up the chapters so you aren't drowned in theory's and technical terms....

...help to study and manipulate the universe: Russian, Chinese and American. Perelman and American scientist Hamilton made the main thing – they found a way to comprehend the shape of our universe. The film is about the knowledge of the universe and people who learn it. It is also about the ethical "standards" in science and scientists forced conformism ... Fragments of an interview c G.Y.Perelman: «I’m able to calculate interstices» - Grigori Yakovlevich, you presented the USSR in the mathematical competition in Budapest as far back as you were schoolboy. Then you took the gold medal … - While we were preparing to the competition, we tried to solve the problem, where the ability to think abstractly was an indispensable condition. That abstraction from mathematical logic was the whole point of our daily training. It is necessary to imagine the «small piece of the world» to find the proper solution. - Isn’t it difficult to schoolboys? - If we talk about the conditioned and unconditioned reflexes, the infant learns the world from birth. If you can train arms and legs, why can’t you train the brain? Thanks to our teachers, we are already well studied topology - science that allows us to understand...

It was designed for residential accommodations. Commercial spaces and lodging rooms can be located on the ground floor of the building. Apartments can be seen on the second floor while rooms for bed spacers are on the third floor. One of the researchers is a client of Pet Pars found out that Pet Pars are currently encountering problems on monitoring their rooms every month and their clients every now and then. They do the monitoring on their rooms and clients manually which is too much of a hassle and time consuming, which can also be a hindrance for business' upgrade. Today’s generation is bombarded with many high technology materials or gadgets which they are using in their daily activities in lives. Therefore, the researchers are thinking on what system will they use to lessen the time that can be consumed during monitoring and how to make monitoring hassle-free and how can they help this business grow especially now that there are...

...In physics and mathematics, the dimension of a space or object is informally defined as the minimum number ofcoordinates needed to specify any point within it.[1][2] Thus a line has a dimension of one because only one coordinate is needed to specify a point on it (for example, the point at 5 on a number line). A surface such as a plane or the surface of acylinder or sphere has a dimension of two because two coordinates are needed to specify a point on it (for example, to locate a point on the surface of a sphere you need both its latitude and its longitude). The inside of a cube, a cylinder or a sphere is three-dimensional because three coordinates are needed to locate a point within these spaces. In physical terms, dimension refers to the constituent structure of all space (cf. volume) and its position in time (perceived as a scalar dimension along the t-axis), as well as the spatial constitution of objects within—structures that correlate with both particle and field conceptions, interact according to relative properties of mass—and are fundamentally mathematical in description. These, or other axes, may be referenced to uniquely identify a point or structure in its attitude and relationship to other objects and occurrences. Physical theories that incorporate time, such as general relativity, are said to work in 4-dimensional "spacetime", (defined as a Minkowski space). Modern theories tend to be "higher-dimensional" including quantum field and string theories. The state-space of quantum mechanics is...

...Science is not extraordinary, nor is its contemporary indication the aftereffect of inexplicable conception. In the event that we remain in amazement of Science, we remain in stunning of ourselves. The historical backdrop of science is not just an argumentative improvement of a relationship of individuals with nature, additionally of researchers with their hypotheses, and researchers with society. We can summarize three interrelated qualities: 1. The relationship between metaphysics and science. Early science was supernatural and bound up with religious convictions about nature and the universe. 2. The social position of science. This involves various attributes. The main is the division of investigative movement and regular action. The second is the relationship in the middle of science and society, in which the character or force of one has been a developmental impact upon the other. The third trademark is the force of science can be used or force: tested from society. 3. The cognitive development of human beings. The learning limit and thinking capacity of researchers has created and expanded incrementally through the historical backdrop of science. The subjective capacities of researchers at every phase of science have been an essential trademark and at times constraining element. Science in the twentieth century It is ordinary these days for researchers and science journalists to grumble about the absence of general society comprehension of science. In any case...

...What is time ? Time is our universe's fourth dimension. It is something that is relative from an observer to another. Time is measured in physics by the speed of light. The speed of light in a vacuum, is constant for all observers. It is 30,000 KM/Sec. But as time is the fouth dimension in our universe, we should ask, what is a dimension ? A dimension, is a measurment required to define the characteristics of an object. There are some theories, that explain dimensions as a measurment created by the brain. What does that mean ? These theories, state that all dimensions exist within our universe. But our brain does'nt the ability to observe all the dimensions at once. What i mean is that the universe has only one dimension, but it is our brain perception that divide this dimension into many other dimensions. Let's have an example according to this theory: This theory says, that all events occur in the same time, or to be more specified, there is no time. But our brain does'nt have the ability to percieve all these information at the same time, so it created the dimension of time to put the events into series. Only less than 10% of our brain is active. And the more the technological advancment develops, the more this brain activity decreases. So, to support that theory, we have an example that explains a lot. Sometimes when we sleep, we dream of some events, and they really occur when we wake up. There are two explanations for that phenomena. First one: Some people...

...Jose Amaro Phys-202 Extra Credit LSST Astronomy has been growing more and more everyday, new discoveries, enhanced telescopes, new stars, galaxies and more have been found and discovered. Everything about the world we live in, space, and the entire universe is fascinating. The only problem is it takes such a long time to learn even more about more planets, maybe even life somewhere in the universe that we don’t know of, or to learn more about other galaxies and stars. The technology we have today takes years and years to just retrieve data and sometimes a lifetime. Although, there has been a new invention, located in South America, that can answer many important questions asked about the universe, space, and where we will. The invention and facility that will answer many question and enhance astronomy is called the Large Synoptic Survey Telescope or LSST. This telescope is has all new technology that is going be used for wide spread use, such as a camera that is 3200 megapixels which is the largest digital camera in the world, data management that takes 30 terabytes of data nightly and instant alerts on any object that change in position or in brightness, and a telescope that has two aspherical optical surfaces, this is also an ground telescope. Its also located in Cerro Pachon, Chile, but why? Its because location of the LSST had to be done by a international site election committee. To place this telescope light pollution, high altitudes, and dry climates came into...

...This term was coined by Edward T. Hall in 1962. He made numerous interviews/studies, in which, he concluded that there are certain spatial distances in which human beings react differently. Hall proceeded to define the personal spaces that surround individuals, as follows: “Intimate space—the closest "bubble" of space surrounding a person. Entry into this space is acceptable only for the closest friends and intimates. Social and consultative spaces—the spaces in which people feel comfortable conducting routine social interactions with acquaintances as well as strangers. Public space—the area of space beyond which people will perceive interactions as impersonal and relatively anonymous” (Brown, n.d., para. 3). Criminal investigators are aware of this technique and also apply proxemics during interview/interrogation process. “Interviews probably start off in the social space; asking the suspect simple information” (“Interrogation Techniques using Proxemics”, 2011, para. 1). Beginning the interview in the social space allows the investigator to ask general questions, however when interrogating the suspect it is advisable to move in closer to the suspect. As the investigator continues with the interview, moving in on the suspect’s intimate space will make it uncomfortable for the suspect to be dishonest. Another technique that investigators/interviewers also use is open-ended and closed-ended questioning during their interview process. “Alternating between the two encourages...

...culture and a discipline of social science, has sustained a growing interest in confronting the underlying heteronormative rules that constrain much of its design.” (Ingram, Bouthilette, and Retter.) In architectures implementation of a heteronormative social construct I wish to explore the capacity for the residual space, public realm to push back. Architecture, as the design of human activity and not simply a function and form has been able to contribute to the creation of safe space and I will be attempting this exploration by looking into how it has underwritten ideas of masculinity in hip-hop culture. I am doing so through visuals to see if and how over the years, environments for expression have offered...

...CAN PAST TALK TO US INTRODUCTION 1. A few years back a movie titled ‘Jurassic Park’ was released and soon became box office hit. When I saw the movie I was astonished and impressed by the on screen appearance of the huge creatures, the dinosaurs, of different variety. The object of appreciation was, of course, the computer generated graphics and animation. But more than that, I was really amazed by the knowledge the people had about these wild monsters, who are the species extinct for almost 65 million years. How do these people come to know how did these creatures look like, what were their food habits, how did they live and how did they evolve? A question came to my mind, ‘CAN PAST TALK TO US?’ . 2. A few years later another movie was released, ‘The Mummy’. This time it was the Egyptian culture that was depicted. Incidentally this culture has also been extinct for thousands of years. It is believed that this culture was in existence some 4500 years ago. Where did the knowledge of the life style of the ancient Egyptians, their religious practices, their culture, their language and their houses, clothes and weapons come from? Could the past possibly have talked to the producers? 3. I am sure these questions must have surfaced in your minds also. If I was to answer these questions, I would say, yes, the past can talk to us. But only through an interpreter. This interpreter is called an ‘ARCHAEOLOGIST’. 4. Good morning lady and gentlemen, today...

...Heckathorn using materials from a program called Operation Physics and includes materials developed by him. The original OPERATION PHYSICS activity sequence to improve physics teaching and learning in upper elementary and middle schools was funded by the National Science Foundation. Original Material Copyright 1992 by American Institute of Physics Materials edited and photoduplicated with permission. FORCES & MOTION INTRODUCTION WORKSHOP LEADER’S TOPIC INFORMATION INTRODUCTION TO FORCES & MOTION An understanding of force and motion is fundamental to the study of almost all other physics-related topics. Yet it is a topic often overlooked or only cursorily introduced in elementary and middle school science, even though it is a topic typically identified for inclusion in the curriculum for these grades. A primary reason for this is that many teachers do not feel comfortable about their own understanding of the topic. Consequently, this may be the most needed of all of the OPERATION PHYSICS workshops. This workshop leader’s notebook is divided into two parts: PART ONE Motion Part One begins by introducing participants to the concepts of space and time. These concepts are then used in describing simple types of motion. These motions are then classified as accelerated and not accelerated (constant velocity). Emphasis is placed on distinguishing between speed and velocity, between average and instantaneous values and on accelerated...

...The Effect of Time and Temperature on Storage of Fresh Pechay I.Introduction A. Objectives The study is performed to discuss the effect of time and temperature on the storage of fresh pechay. It is also done to explain the difference of low and high temperature on the storage fresh pechay. Lastly, to explain other factors related to time and temperature that may affect the storage. Through conducting this study, the proper storage conditions of food items will be determined. B. Significance of the Study The study aims to show the effect of time and temperature in the storage of fresh pechay. This will determine whether the fresh pechay will react positively or negatively towards the conditions of its storage. This study will be using two set-ups which will be observed three times. One of the set-ups will be placed in a place with room temperature only, around 30º C. The other set-up will be placed inside the refrigerator, about 48º F. The effectivity of the two different set-ups will be indicated by the resulting qualities of the pechay bunches. This will be helpful in determining the proper storage techniques that will maintain the physical and nutritional qualities of food items. This experiment is done in the Bio-assay Laboratory, Institute of Human Nutrition and Food, College of Human Ecology, UPLB. II.Review of Literature Pechay, scientifically known as Brassica rapa chinensis, is considered as one of the popular vegetables here in the Philippines...

...been discussed by a variety of scholarly voices. Among the most prominent is Michel Foucault, who described the various ways that consumer markets circumscribe public spaces, placing important distinctions between class members. In particular, Foucault discusses heterotopia – the public space which carries both physical and psychological gravity. For Foucault, public spaces are characterized by existing without truly existing. The heterotopia serves as a metaphor for a larger context while having the appearance and characteristics of other everyday spaces. Tyndall takes this notion a step further by developing social rules that are attached to consumer places, such as malls and shopping districts (Tyndall, 2009). This version of consumer-driven rules – culled from qualitative research and personal interviews – depicts a new notion of public-ness that is less egalitarian than ever before. It is a version of public space that is not entirely open to the public. Baker adds to this perspective by historicizing the commercialization of public space, dating the use widespread use of public space for advertising purposes to before the dawn of the 20th century (Baker, 2007). This argument inextricably links the notion of “culture” with “consumerism”, and sets the stage for the potential for access to public spaces to be consumed, or purchased. Finally, Klingle underscores this spatial history of consumption, placing the transaction of consumer power contexts as diverse as Thoreau’s...

In order to cure is father from his suicidal tendencies, Edgar used imaginary place to cure him. Rhetorical skills, it can be seen on the stage because it’s a bare stage and it was invented by Edgar to fool him. He plays with the fact his father is blind. The main passage is on paradoxes. The madman leads the blind man. Dramatic irony= when you know more than the character -> different from tragic irony= when a character do an action without knowing that it’ll have a tragic consequences.

Space is not static it’s very dynamic it’s following the falling of someone from the edge of a cliff -> vertical traject. Describe in a metonymic way => metonymy= a figure of speech which use a part to describe the whole or the whole to designate the part. It appeals to motion it’s a downward movement, a change of perspective. It anticipates on the movement of the fall and it’s also strategic as Edgar considers it.
