It just has multiple theories, and then one eventually corresponds to the regularities of nature, and that is how science acquires empirically successful theories. All the other theories, that turn out to be empirically inadequate, simply do not survive. So although there is no miracle involved in science’s empirical success, truth is not is not the sole assistant either. He is substantially saying that science has at its disposal many different theories, and upon testing their empirically adequacy, they conclude if it is true or not. That would entail that the aim of science is empirical success first, and truth
Purpose This lab was designed to mirror elite scientists who design objects that can survive the forces of Mars or the Moon. This goal allowed us to design a contraption involving a raw egg that would be dropped from 2 meters, the condition of the raw egg after contact would be paramount to the overall success of the project. The proper procedures taken in this controlled experiment is similar to the regulations scientists in NASA must be weary of. Background As learned in class, momentum is the quantity of motion1. Momentum plays a crucial role in this experiment since the greatest difference in other designs will be in momentum along with mass, we have also learned that mass is the quantity of matter in a body.
It was devised by German-American mathematician Max Munk and further refined by British aerodynamicist Hermann Glauert and others in the 1920s. The theory idealizes the flow around an airfoil as two dimensional flows around a thin airfoil. It can be imagined as addressing an airfoil of zero thickness and infinite wingspan. Thin airfoil theory was particularly notable in its day because it provided a sound theoretical basis for the following important properties of airfoils in two-dimensional Flow: (1) On a symmetric airfoil, the center of pressure and Aerodynamic center lies exactly one quarter of the chord Behind the leading edge (2) On a cambered airfoil, the aerodynamic center lies exactly One quarter of the chord behind the leading edge (3) The slope of the lift coefficient versus angle of attack Line is 2π units per
Humanity is fragile and mysterious and not always subject to the laws of the universe. Crisis is also not subject to these laws and thus does not need to be met with prescribed solutions. Sir Isaac Newton gave us incredible insights into the scientific world and his findings shaped our history, however when it comes to crisis management we need to throw away laws, boundaries and expectations. This is because these laws relate to the physical world and crisis is not always physical, rather it can occur on an intellectual or emotional level. We need to find and use our own confidence and listen to our instincts.
Polyurethane are also commonly used as constituents of paints, varnishes, adhesives, and foams. Memory foam was initially referred as the “slow spring back foam” It is created by inserting and feeding gas into a polymer matrix. The foam has an open-cell solid structure that when pressure is pressed against it, it stays in that state and slowly springs back to its original shape. It is also made from a substance called viscoelastic. Memory foam was developed in 1966 under a contract by NASA's Ames Research Center, the intended problem that this technology was suppose to solve was to improve the safety of aircraft cushions.
He claims that his doubt is reasonable on the theoretical level, and his radical doubt will not impede him from practical life, since he is only consider the question of epistemology. In other words, his skeptical method does not concern local issues or physical matters in the external world, but only with abstract, general truths, whose validity is not dependent upon “whether they are actually existent or not” (Descartes, trans. Haldane I-7). Indeed, Descartes’ method of doubt is revolutionary in the sense that the uses doubt as a tool to search for a general, firm, and universal principle that serves as the basis of knowledge and an antidote for skepticism. The method he invented — the radical and methodical doubt —is a reproducible model for demarcation between subjective opinions and objective truths.
Also, while the humans understand that they were the ones to have created him, it is mentioned that “[t]hey [...] knew, of course, that Hal was hearing every word, but they could not help these polite circumlocutions. Hal was their colleague, and they did not wish to embarrass him” (Clarke 18). Here, it is clear that Hal is not deemed a mere machine, but a peer. The problem lies herein that Hal was created by imperfect creatures, humans, and therefore is not a perfect example of true artificial intelligence. He was programmed to abide to a set of rules that had come from a human mind, which caused them to be inherently flawed.
Also the error bars on the time distance are present but they are so small it is not a significant enough number to show on the graph. The error bars are the same as the uncertainty on the instruments. The data points on the graph show that the line of best fit includes all the data within the error bars and so the data is moderately precise and the results are reliable. The limitations of the experiment were that the exact measurement of the distance and time were both done by hand and so there is human error involved. Also we can see that because the data was taken at a certain time the results will not work for all times of the day.
(Russell 2014) Conclusion: Despite controversy Milgram’s experiment was ground breaking. It remains relevant today and is frequently cited in demonstrating the perils of obedience. Milgram himself concluded how easily ordinary people ‘can become agents in a terrible destructive process. Moreover, even when the destructive effects of their work become patently clear, and they are asked to carry out actions incompatible with fundamental standards of morality, relatively few people have the resources needed to resist authority". (Milgram 1974) As this report has highlighted the research is not without controversy with many questioning to what extent Milgram’s experiment is true to real life and has been criticized for not highlighting further situational variables in determining obedience to authority.
Drag coefficients are found to increase quadratically with increasing angle of attack. Both lift and drag coefficients are found to increase with increasing camber. Experimental results for finite wingspan airfoils are compared to published section data for infinite wingspan airfoils, revealing significant differences. Using wind tunnel data, the NACA 1408 is chosen as the optimal airfoil for aircraft landing and racecar spoiler applications, while the NACA 2412 is chosen for an aircraft at cruise conditions.
Analysis - To initially get the position vs time graph, the whiteboard ramped was marked every half meter and four time trials were done going to every mark. the times were then averaged and plotted on a graph. With each average time a velocity was calculated by distance/time and those were averaged to find the velocity (because the buggy was a constant speed there is only need for one velocity). With this, it turned out the slope of the position time graph was the velocity. If there was a non constant velocity, the derivative of the position time graph would yield the velocity for the specific time.
The fighters would now have the guns mounted in the wings, making the need for the interrupter gear obsolete. The first class fights of Brittan, Germany, and the United States required powerful aero engines suitable for compact low drag installation. The only exception to this was the Japanese Mitsubishi A6M, known as the zero. The Zero was so strong and light that it achieved first class performance with a second class engine. The aircraft of WW2 were now heavily armed.
Humanity can’t fully realize how bad they are or what it is that is so bad about them without experiencing or being able imaginatively to represent what they’re like to us. In other words, is not relevant knowledge when we only know about evil but haven’t felt it or experience it. In comparison to Eden there were no evil. So Adam and Eve according to the traditional story did not have the relevant experience that would have given them the kind of full-body knowledge that would have permitted them to be fully responsible for what they did. Therefore, her conclusion is that classical appeals to free will to solve the problem of evil are not effective without further supplementation.
