Research Experiment to Determine the Speed of Sound - Abstract/Introduction: Sound is the sensation that our brain interprets when vibrations carried to our ears stimulate the auditory nerves. It is produced by the compression and rarefaction of matter. The speed of sound depends on the properties of the medium such as bulk modulus, density and the temperature though which it travels. It does not depend on the source of the sound. Sound travels faster in air which is less dense and in air with a higher temperature. Hence, more density and heat = faster speed of sound....   [tags: physics, Physics Experiment] 1972 words

Comparing Views on Stanley Milgram's Experiment on Obedience - In 1963 a psychologist named Stanley Milgram conducted one of the greatest controversial experiments of all time. Milgram tested students from Yale to discover the obedience of people to an authoritative figure. The subjects, whom did not know the shocks would not hurt, had to shock a “learner” when the “learner” answered questions incorrectly. Milgram came under fire for this experiment, which many proclaimed was unethical. This experiment of Milgram’s stimulated the creation of several responsive articles....   [tags: Ethics, Article Comparison]

An Experiment with an Air Pump - An Experiment with an Air Pump Is it ethical or even helpful to try to impose order on a haphazard existence. Is it right to play God, to steal the limelight from the cosmos. Man used to ponder existence, but with the increasing possibilities of science, we now ponder our power over existence. In “An Experiment with an Air Pump,” Shelagh Stephenson uses symbolism associated with Isobel as a voice of foreboding in a society “enraptured by the possibilities of science” (3). Stephenson associates Isobel with a bird, a pile of bones, and a sheep to reveal the dark side of the “light,” the scientific revolution....   [tags: Shelagh Stephenson Science Technology Essays] 908 words

Experiment to Show the Rate of Photosynthesis - Experiment to Show the Rate of Photosynthesis Aim: Experiment to show the rate of photosynthesis when pondweed is under different life intensities. Prediction: I predict that the closer the light is to the pondweed the (or the higher the light intensity) the more oxygen will be produced until a certain point where the temperature or carbon dioxide levels will be the limiting factor. The further away the light, the slower the oxygen bubbles will be produced so the less light the less photosynthesis will occur which is needed for the plant to make food....   [tags: Papers] 648 words

The Cartesian Doubt Experiment and Mathematics - The Cartesian Doubt Experiment and Mathematics ABSTRACT: The view that Descartes called mathematical propositions into doubt as he impugned all beliefs concerning common-sense ontology by assuming that all beliefs derive from perception seems to rest on the presupposition that the Cartesian problem of doubt concerning mathematics is an instance of the problem of doubt concerning existence of substances. I argue that the problem is not 'whether I am counting actual objects or empty images,' but 'whether I am counting what I count correctly.' Considering Descartes's early works, it is possible to see that for him, the proposition '2+3=5' and the argument 'I think, therefore I am,' were equal...   [tags: Mathematics Math Mathematical Papers] 3426 words
