  • Technological Advances Greater Understanding

    ... it does not interfere with our understanding of our being and essence. We could to easily get caught up in our devises and let them rule our lives. Heidegger feels it would be a supreme danger for them to define our being. The saving power would be our understanding of our being and using those gadgets only as means to their end. I think Heidegger would not respond favorably to our technology of mass media and electronic communications. Our society seems to see our technological advances as ...

  • Sheet Of Paper Focal Length
    1,152 words
    Aim: To examine characteristics of a converging lens and the images they create. Also to examine the focal length and how the focus point may be found and developing rules for locating an image via ray drawings and the intersection of rays. Chromatic aberration will also be explored and why it happens. Theory: Both lenses and mirrors have a principle axis, yet a lens has two focal points as opposed to a mirror that has only one. When considering converging lenses, the primary focal point (PF) ca...

    ter>Sam Vaknin's Psychology, Philosophy, Economics and Foreign Affairs Web Sites In 1936 an American (Alonzo Church) and a Briton (Alan M. Turing) published independently (as is often the coincidence in science) the basics of a new branch in Mathematics (and logic): computability or recursive functions (later to be developed into Automata Theory). The authors confined themselves to dealing with computations which involved effective or mechanical methods for finding...

    The Soviet Union was a global superpower, possessing the largest armed forces on the planet with military bases from Angola in Africa, to Vietnam in South-East Asia, to Cuba in the Americas. When Mikhail Gorbachev succeeded Konstantin Chernenko as General Secretary of the Central Committee of the Communist Party of the Soviet Union in March 1985, nobody expected than in less than seven years the USSR would disintegrate into fifteen separate states.

    ... also found 'resistance' again, usually in the more experimental pieces, including, famously, Madonna videos (see Fiske 1989 for an example of how Madonna fans have used Madonna videos to develop their own empowering versions of femininity). Again, much of this needs researching further and in a more recent framework. I have suggested that work in media studies offers a basic kind of approach to all elements of popular culture -- you could look at the representations and narratives in adverti...

  • Hydrogen Peroxide Degrees Celsius
    539 words
    Catalase Which Is Found In The Liver' Introduction: Enzymes are biological catalysts. They speed up the chemical reactions which go on inside living things. Without them the reactions would be so slow that life would grind to a halt. Enzymes work by when a substrate molecule bumps into a molecule of the right enzyme, it fits into a depression on the surface of the enzyme molecule. This depression is called the active site. The reaction then takes place and the molecules of product leave the acti...

  • Objective Reality Existential Mode
    1,646 words
    Discuss Bauman (1) Since the end of WWII, many people become disillusioned with the traditional view of history as the process of continuous progress. The positivism, as philosophical method, began to lose its appeal even before this. It was becoming obvious for many philosophers that human behavior cannot simply be defined by economical factors, as Marxism suggests, and neither can we think of such behavior as being exclusively motivated by ethical considerations. This coincided with the emerge...

  • Acute Law

    Introduction This group experiment was to investigate Boyle´ s Law. It was named Boyle´ s Law, after Robert Boyle, who made the discovery. The experiment involved compressing a certain amount of air molecules into a smaller space. The way to do this is to trap the air in between the top end of a glass tube and a very thick layer of oil. Below, is a picture of how we had to set out the apparatus. Apparatus Volume scale Air pump Glass tube Pressure gauge Oil Method and Prediction Using...

    It is impossible for me to say whether or not I agree completely with Ian Hacking's work, not having read Kuhn's work, Foucaults work or even Hacking's work in its entirety, however by examining Hacking's claims individually, it may be possible to draw conclusions through the analy zation of his arguments. Ian Hacking's most prevalent claim seems to be that we make up people in a stronger sense than we make up the world. By proving this, hacking is attempting to show why Kuhn was unsuccessful in...

  • Hearing Loss Paying Attention
    1,121 words
    The ear is the organ of hearing and balance in vertebrates. The ear converts sound waves in the air, to nerve impulses which are sent to the brain, where the brain interprets them as sounds instead of vibrations. The innermost part of the ear maintains equilibrium or balance. The vestibular apparatus contains semicircular canals which in turn balance you. Any movement by the head, and this apparatus sends a signal to the brain so that your reflex action is to move your foot to balance you. The e...

  • Bunsen Burner Hydrochloric Acid
    762 words
    The Problem: I am going to find out how temperature can affect the rate of reaction. Background information: Factors that change the rates of reactions are: ? Temperature? an increase in temperature will make the reaction occur faster. This happens because the particles of that substance move faster when it is heated. Because the particles move faster, they would collide more, making the reaction rate faster. ? Concentration? the increase in concentration, the greater and faster the reaction. Th...

    Parallel Plate Capacitor and Dielectrics Different materials were placed in between the plates of a parallel plate capacitor and the change in capacitance for each of the materials was tested using a galvanometer. The results were studied to determine the dielectric constant for each of the dielectric materials and to determine the permittivity of air. By its self, results show that the parallel plate capacitor? s capacitance is inversely proportional to the distance between the plates. This rel...

    ABSTRACT Ohms Law and Kirchhoff's rules is fundamental for the understanding of dc circuit. This experiment proves and show how these rules can be applied to so simple dc circuits. INTRODUCTION In the theory of Ohms Law, voltage is simply proportional to current as illustrated in the proportionality, V = RI. As shown in this relation, V represent voltage which is the potential difference across the two ends of a electrical conductor and between which an electric current, I, will flow. The consta...
