...Questions and Answers for Conceptual Physical Science Practical 1. How many rolls did it take for the number of each colored cube to be reduced by half? These are your half-life readings One-side color: 8 throws Two-side color: 5 throws Three-side color: 3 throws 2. The half-life of a decaying substance is measured in units of time. What is the unit of half-life used in this simulation? Remaining per throw 3. In each case, how many rolls did it take to remove all the cubes? One-side color: 24 throws Two side color: 19 throws Three-side color: 17 throws 4. In which of these hypothetical substance would be the most radioactive? The substance that will decay much faster is the third substance represented by black on the three sides of the cube. According to my tabulation, the curve for the third substance appeared much steeper and at the seventeen throw no cubes were remaining. 5. How might you simulate the radioactive decay of a substance that decays into second substance that also decays? First, the substance always decays because the initial stage is not stable. Lack of stability forces the substance to decay into a second substance with a loss of either an electron, energy or a proton. If the second substance is not stable, it will disintegrate into the third substance. This process might continue until the substance gain stability. 6. Is it possible to estimate the half-life of a substance in a single throw? How accurate might this estimate be? Yes, this is...

...Is Science the only sure path to Truth? Physics is “the branch of science concerned with the nature and properties of matter and energy. The subject matter of physics includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms” (Oxford Dictionaries). Till the first half of the eighteenth century, physics was a branch of natural philosophy. It “became widely used in its modern sense (i.e., excluding the life sciences, geology, and chemistry) during the second half of the eighteenth century” (Olson, 2002, p. 301). Olson (2002) explains how physics is divided into two main categories. He states that topics treated before the middle of the last decade of the nineteenth century are said to be parts of classical physics. On the other hand a group of topics that emerged after about 1895 is said to make up modern physics. Since physics is a broad area, in this essay, I specifically focus on one topic from modern physics, namely quantum physics. I will evaluate whether quantum physics can lead us to ‘Truth’. In this paper, ‘Truth’ refers to quantum events. First, I will portray how quantum events are filled with uncertainties; I will then list three answers given by physicists to explain why uncertainties are present. I will then move on to show how quantum physics offers conceptual parallels to ideas in religion. I will mainly discuss the role of holism character in quantum systems. Finally I will evaluate whether god is the reason...

...Isac Newton was born on on January 4, 1643, in Woolsthorpe, England. Newton attended King’s School in England. Once he completed his primary education he moved on to Cambridge. As he studied there he became fascinated with physics and read up on many philosophers. After graduation he went on to his own research before attaining a masters later in his life. Possibly the most important theory Newton ever came up with was gravity. It is commonly believed that Isaac Newton begin to think about gravity and its properties after an apple fell on his head, or simply by observing falling apples. Wether this is true or not, we may never know. The point is that Isaac Newton was a brilliant minded physicist before he even began to thing about calculus....

...Mechanical Philosophy During the sixteenth and seventeenth centuries, natural philosophers were starting to reject Aristotelianism and began finding other forms of natural philosophy to study and believe in. One of the popular philosophies in the seventeenth century was mechanical philosophy. “Mechanical Philosophy sought to explain all natural phenomena in the terms of matter and motion without recourse to any kind of action at a distance (cause and effect without any physical contact) (Mechanical Philosophy).” This paper will go into detail about the mechanical philosophy’s background, advocates of the philosophy and later developments. The mechanical philosophy was foreshadowed in Galileo and Kepler. As the seventeenth century was coming to an end, the general public agreed that the universe was made up of small solid corpuscles, which moved and changed in direction as they were bumped by each other. The material atom was in favor of the mechanical philosophy. This philosophy originated from the views of the Greek philosopher Epicurus. He always looked for the main key for a good life. “Epicurus believed that the greatest sources of human unhappiness, apart from bodily pain, are fear of the gods and anxiety about punishment after death (“Mechanical Philosophy”).” His version of atomism is how the conclusion of a human soul is material, composed of atoms that are very small came up in science. Soon after Epicurus claimed this was true he exposed that the gods’...

...on What is the Relation between Science and Religion William Lane Craig Examines several ways in which science and theology relate to each other. Back in 1896 the president of Cornell University Andrew Dickson White published a book entitled A History of the Warfare of Science with Theology in Christendom. Under White’s influence, the metaphor of “warfare” to describe the relations between science and the Christian faith became very widespread during the first half of the 20th century. The culturally dominant view in the West—even among Christians—came to be that science and Christianity are not allies in the search for truth, but adversaries. To illustrate, several years ago I had a debate with a philosopher of science at Simon Fraser University in Vancouver , Canada, on the question “Are Science and Religion Mutually Irrelevant?” When I walked onto the campus, I saw that the Christian students sponsoring the debate had advertised it with large banners and posters proclaiming “Science vs. Christianity.” The students were perpetuating the same sort of warfare mentality that Andrew Dickson White proclaimed over a hundred years ago. What has happened, however, in the second half of this century is that historians and philosophers of science have come to realize that this supposed history of warfare is a myth. As Thaxton and Pearcey point out in their recent book The Soul of Science, for over 300 years between the rise of modern science in the 1500’s and the late 1800s the relationship...

...Hawking contra Philosophy Christopher Norris presents a case for the defence. Stephen Hawking recently fluttered the academic dovecotes by writing in his new book The Grand Design – and repeating to an eager company of interviewers and journalists – that philosophy as practised nowadays is a waste of time and philosophers a waste of space. More precisely, he wrote that philosophy is ‘dead’ since it hasn’t kept up with the latest developments in science, especially theoretical physics. In earlier times – Hawking conceded – philosophers not only tried to keep up but sometimes made significant scientific contributions of their own. However they were now, in so far as they had any influence at all, just an obstacle to progress through their endless going-on about the same old issues of truth, knowledge, the problem of induction, and so forth. Had philosophers just paid a bit more attention to the scientific literature they would have gathered that these were no longer live issues for anyone remotely au fait with the latest thinking. Then their options would be either to shut up shop and cease the charade called ‘philosophy of science’ or else to carry on and invite further ridicule for their head-in-the-sand attitude. Predictably enough the journalists went off to find themselves media-friendly philosophers – not hard to do nowadays – who would argue the contrary case in a suitably vigorous way. On the whole the responses, or those that I came across, seemed overly anxious to strike...

... GE 253 Physics Albert Einstein’s Contribution to Quantum Mechanics Albert Einstein was one of the greatest minds in world history. Einstein is known as a brilliant physicist who contributed more to the scientific world than any other person. His theories on relativity paved the way for how science currently views time, space, energy, and gravity. Einstein was so advanced in his thinking that his studies and work set the standards for the control of scientific energy and space explorations currently being studied in the field of astrophysics. Albert Einstein's most noted contribution to the world is his theory of relativity. By 1902, Einstein was working on combining time and space, matter and energy. In 1905 when he was only 26 years old, he published a paper on relativity. This paper showed mathematically that the speed of light is constant and not relative to its source or to the viewer. Einstein had actually written an essay when he was only 16 years old on relativity, which became the basis for his published paper. The greatest result of relativistic physics was Einstein's famous relation, E=mc2. In this, he was able to prove that any increase in the energy, E, of a body must lead to a corresponding increase in its mass, m, these increases being related by a factor c2 , where c represents the velocity of light squared. In conclusion, Albert Einstein ranks as one of the greatest people for his contributions towards physics and his part...

...Physics is all around us. It is what causes the lights to buzz with electricity, the car on the streets to go from point A to point B, and our televisions to run so we can watch our favorite shows. According to Webster dictionary, physics is the science of matter and energy and of interactions between the two. In all physics consists of energy, kinetic energy, potential energy, velocity, acceleration, mass, force, and gravity. Without physics many things would not be possible. In fact, when a person is driving their car they are suing momentum (the quantity of motion of a moving object) and acceleration. Over time our general understanding of physics has helped us develop greater technology than society thought possible. For example, many years ago society believed that flight was impossible until two brothers, the Wright brothers, invented the aircraft. Now of course that was with many trial and errors. According to Bernoulli principle an increase of a flow results in a decrease of pressure. When air hits the leading edge the airflow above the wing travels faster than the flow below the wing. So therefore, the pressure below the wing will be higher than the air pressure above the wing. Because of this difference in pressure, lift is created, and pushes the wings upward. Be that as it may, this is not the only physics principle at work One must also apply Newton’s 1st (every body remains in a state of rest or uniform motion unless it is acted upon by an external unbalanced...

...Name Professor Course Date Isaac Newton the Last Magician Biography This is a one hour movie documentary narrated by Helen McCrory trying to give an insight to the life of Isaac newton and how he changed our understanding about how the universe works. The documentary asks question to experts of the history surrounding Isaac newton. In the documentary Isaac newton is brought out as a pessimist as he would enjoy his own company, his life revolved around research and a lot of studying in the laboratory in religious activities like heretical, alchemy and also the study if the hidden. Newton did not believe anything that he read, this was evident when he was the age of twenty one by declining to agree with scientific research which was more than two millennia old and decided to come up with his own through conclusion and to do this he had to perform a number of experiments. We get the notion that he was a skeptic and anything could be questioned of its legitimacy. Newton had a secretive life that came to light two hundred years after his death, this was his passion for cultic behavior where he considered himself a scientific Christ who was sent to save the world from scientific fiction, this is ironic as he was also born on Christmas morning just like Jesus the messiah in the bible. He is called the last magician because after his death there has not been any other iconic person like he was that has made a fraction of the changes in science that he did. His discoveries...

He wanted to represent his country at the United Nations. Even though he was still in high school, he formulated a plan to achieve this goal of representing the Netherlands in the United Nations. He decided to get a law degree. After receiving the maximum highest points possible in the following areas: mathematics, chemistry, biology and physics on his final examine. Everyone starting with his loving and supportive parents to his very motivational teachers convinced Edsger that a career in the field of science would be an outstanding career move for him. So, Edsger Dijkstra headed on to the University of Leyden. There at the University of Leyden Edsger Dijkstra decided that he would major in Theoretical Physics. To develop a good, strong and firm foundation in Theoretical Physics Dijkstra began his studies in mathematics and physics. Douwe Wybe Dijkstra being the loving and supportive father that Edsger needed him to be, was always searching for great opportunities to encourage his son in the field of study that he had chosen. Well, as the story has it, Douwe, (Edsger father) was reading a paper and just happened to come a cross an advertisement for a computer programming course that would be held at Cambridge University in England. The computer programming course was three weeks long. The three week course was to start...

...German-born American theoretical physicist, Albert Einstein, often regarded as the father of modern physics, had exceptional intellectual ability and unprecedented insight. Many believed him to be one of the most influential people in both science and mathematics, and quite possibly the most famous scientist of the 20th century (Severance, 1999). As cited by Fingon and Fingon, Einstein was well known for being a brilliant physicist and abstract thinker, applying his creativity and imagination in his scientific thought process (Parker, 2003). He received the 1921 Nobel Prize for his contribution to the study of physics, namely his special (1905) and general (1916) theories of relativity. The name “Einstein” is often thought of as being synonymous with the word genius. Einstein was not always thought of as a genius, however. His unique intellectual abilities as a young boy created challenges for him in his everyday home and school life, but his sense of wonder paired with persistence and determination led him to be the successful prodigy people know him as today. Abraham Maslow’s humanistic approach of self-actualization provides significant explanation for Einstein’s behaviors and achievements throughout his life. Heredity and environment played vital roles in Einstein’s psychological development. Einstein’s parents and teachers observed his early childhood developmental delays and had doubts regarding his intelligence. His parents worried about his intellectual development...

...Albert Einstein is regarded as the father of modern physics. He was born on march 14 1879 Ulm, in the Kingdom of Wurttemberg in the German Empire. In his early life he studied calculus and philosophy and discovered different formulas which basically changed this world. He was basically German born theoretical physicist who developed the general theory of relativity. As a result of this achievement he is regarded as the father of modern physics and the most influential physicist of the 20th century. Albert Einstein in fact changed the scientific world with his achievement when he gave the idea of E=mc2. In this formula that clearly described that the energy and mass (the ability to do work and the stuff to do work with) were absolutely the same thing. When Newton said that time and space are absolute which means that time flowed in a constant manner. Time is independent of location and remain same for everyone. This idea of Newton was remained unchallenged until Einstein came along. He decided to do experimentation with that and then he theorized that time and space were relative, and in this way he proved that Newton was wrong. With his theory of relativity,Einstein tore apart the idea of time as a constant. I would like to mention there that Einstein published more than 300 scientific papers along with this 150 non-scientific works. He was so intelligent that he made the word "Einstein" synonymous with genius. At the end I would like to mention that Albert Einstein, once...
