Galileo Galilei is one of the most well known and popular scientist beside Albert Einstein. At the very basis of what he did‚ Galileo changed how people looked at the world around them especially the solar system. Eventually the church held a trial against Galileo on the act of heresy and attack on the Aristotelian idea of the universe as the church and many others believed that the earth was at the center of the solar system not the sun. He also had many inventions which helped future scientists

and it keeps you alert for survival. Although‚ it can be detrimental in the sense that it can cause paranoia‚ obsessions‚ and can cloud rational thought. The best examples of this are the main characters in “The Tell-Tale Heart”‚ “The Pit and The Pendulum”‚ and “The Masque of Red Death”. In the stated narratives Edgar Allan Poe shows us how he uses symbolism‚ irony‚ and imagery so he can illustrate how it distorts minds‚ causes fear‚ and the repercussions of the fear. In “The Tell-Tale Heart”

earliest dates are less certain. Some authors‚ however‚ claim that water clocks appeared in China as early as 4000 BC.[2] Some modern timepieces are called "water clocks" but work differently than the ancient ones. Their timekeeping is governed by a pendulum‚ but they use water for other purposes‚ such as providing the power needed to drive the clock by using a water wheel or something similar‚ or by having water in their displays. The Greeks and Romans advanced water clock design to include the inflow

er 3) Physics of roller coasters | | Simply speaking‚ a roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track.[1] This combination of gravity and inertia‚ along with G-forces and centripetal acceleration give the body certain sensations as the coaster moves up‚ down‚ and around the track. The forces experienced by the rider are constantly changing‚ leading to feelings of joy in some riders and nausea in others. The basic principles

presumed the floor the ergometer was placed on was level. A subject was placed on the bike and the “0” mark on the scale was adjusted with the screw in order to correspond with the mark on the pendulum. The forward attachment of the belt was removed from the pendulum. A known weight was attached to the pendulum using a string and the scale reading was recorded. The process was repeated with 3 other known weights and each scale reading was recorded. The data points were summarized in a table and graphed

“I am almost ashamed to own --that the terror and horror with which the animal inspired me” Edgar Allen Poe uses many gothic techniques in his stories‚ but only a handful of those actually give the story character and feeling. Unreliable narrators add a sense of character to the narrator‚ Grotesque gives the story its unique setting‚ and guilt further develops the characters. Unreliable narrators give the reader an outstanding view of the story as it is being told through an unstable person. In

5.2 Energy conversion and conservation 1. A change from one form of energy to another is called an energy conversion. 2. Is the following sentence true or false? Most forms of energy can be converted into other forms. True 3. Describe the conservation of chemical energy to mechanical energy in your body. Your body changes chemical energy which was in your food through the system of digestion. Once the energy is released‚ it turns to mechanical energy to move your muscles 4. When you throw

took the same amount of time to swing back and forth‚ no matter how far it was swinging. When he returned home‚ he set up two pendulums of equal length and swung one with a large sweep and the other with a small sweep and found that they kept time together. It was not until Christian Huygens almost one hundred years later‚ however‚ that the resonant nature of a swinging pendulum was used to create an accurate timepiece. To this point‚ he had deliberately been kept away from mathematics (since a physician

Completion Problems (Elasticity) 1. A steel wire of length 4.7m and cross-sectional area 3×10-5m2 stretches by the same amount as a copper wire of length 3.5m and cross-sectional area of 4×10–5m2 under a given load. What is the ratio of the Young’s modulus of steel to that of copper? For Steel l1= 4.7 m‚ a1 = 3.0 x 10-5 m2 Y1= Fl1/a1∆l Y1= (F x 4.7m)/ (3.0 x 10-5 x ∆l) For Copper L2=3.5 m‚ a2 = 4.0 x 10-5 m2 Y2= (F x 3.5m)/ (4.0 x 10-5 x ∆l) Dividing Steel by Copper Y1/ Y2

The way he describes the torture chamber in “The Pit and the Pendulum” is a good example of Enargia. He does this when he writes “I now observed-with what horror it is needless to say-that its nether extremity was formed of a crescent of glittering steel‚ about a food in length from horn to horn; the horns upward‚ and the under edge evidently as keen as that of a razor...appended to a weighty rod of brass…” (The Pit and the Pendulum). This makes the reader to feel as though they too are in the torture
