Static Electricity:
Everything in our world is made up of atoms and an atom consists of three parts. In the
The stories Conducting Solutions, Energy Story, and the video Hands-On Science with Squishy Circuits have all helped me learn a lot more about electricity. The purpose of these sources were to help the reader to understand and inform the reader about how electricity is made. It also showed how easy it is to make electricity. These three sources have many differences and similarities but they all serve the same purpose.…
He mentions the examples such as the anecdote of Richard Feynman, who believed the writings on paper are actually part of his thought process(Thompson, 348). From those examples, Thompson proofs the modern technologies, similar to paper and printing press, are merely extensions, rather than replacement, of our thinking. In order to illustrate such concept in terms that are close to readers, Clive Thompson writes how was he influenced by modern technologies in the process of writing this article(351). In conclusion of his personal experience, he suggests modern technologies contribute to our thought process with better information and connection (Thompson, 352). In the end of this article, Clive Thompson goes back to the subject of chess.…
Lab 2 Summary In this lab, the purpose was to understand how to use a DMM to measure different things like resistances, current, and voltages as well as how to successfully comprehend the electrostatic relationship between various objects. In the first part of our lab we learned how to use a Digital Multimeter by using a simulator to draw diagrams of circuits. This helped give us a basic understanding that when dealing with a circuit and tools like a DMM, you have to connect wires to certain places and make sure the positive is touching the positive side. In the second portion of the experiment, we learned how to use the equipment that will be used for the other labs.…
The invention of Gutenberg’s printing press is one of the most significant…
Originating from cosmic events such as supernovas, chemical elements are the foundation of all life. Billions of years ago, a violent explosion known as the Big Bang produced helium, hydrogen, and all of the matter and energy in the universe. Generated in the cores of stars, nuclei combined to form atoms which constitute the basic unit of all chemical elements. The extensive expansion of the universe induced the birth and demise of more stars and consequently the creation of more elements.…
2.5 – Nuclear Physics What was initially known about the model of the atom before Thomson and Rutherford conducted their experiments? The first model of the atom is thought to have come from two Greek philosophers - Democritus and Leucippus – in the fifth century BC. These two philosophers believed that everything was made up of matter, and that you could half a given portion of matter (and keep halving the product) and eventually be left with something that couldn’t be halved again: the atom. They believed that all atoms were imperishable and could not be split apart.…
People find out new things about the world every day. Scientific findings are almost never final. Experiments can verify or shatter what we perceive as facts of life. Atoms are an example of this. Thinkers and scientists from throughout time have been theorizing and experimenting to find out what an atom is made of.…
Chemical changes are everywhere from everyday things such as baking to scientific things such as changing one gas into another. Physical changes are changes that can be observed with senses and change a certain property or properties to a substance but it still remains chemically the same. This can include changes in the state of matter, size and shape. Chemical changes are when the substance is changed chemically with its properties changing with it. The substance with change from one substance to another.…
Scientists believe that stars are made of mostly gas, and this gas is made up of many atoms. In the star, the atoms in the gas bang into each other and give off different light depending on the type of atoms. This light from stars enables scientists to figure out the type and amount of atoms they are made of. Knowing the composition of the stars, we can guess how they were formed. Therefore we can see that stars are just atoms (hydrogen) hitting each other producing light.…
The movie Flubber and 9th grade physical science discussed at lot some of the same topics. They both talked about polymers, physical properties, states of matter, catalyst and different types of energy. In this essay I will explain the movie Flubber, while still making the connections to this year's physical science class.…
The death penalty has been in the United States since the first settlements were built. In that time an estimated 16,000 criminals have been put to death since the first recorded execution, back in 1608 (Ford). A amount of those criminals had killed at least one person, and good portion of them would not stop killing until they were stopped. Luckily, the criminals that were planning on never stopping, or were not able to stop, were caught and brought to justice. When the criminal is convicted, the family can feel some measure of relief about what has happened and that justice has been served knowing the criminal is off the streets.…
Tesla and Edison During the late 1890s the inventions of two great minds, Nikola Tesla and Thomas Edison, helped turn electricity from a scientific concept into a household amenity. In this paper, I will review both of these men’s lives, give an overview of their accomplishments, and go over how these accomplishments still have an impact today. Nikola Tesla was born July 10, 1856 in Smiljan, Croatia. A bright child with an almost photographic memory and an aptitude for problem-solving, Tesla was inventing as early as 5 (Cheney 7) and in school he excelled in both mathematics and languages, including German, English, and French (Cheney 14).…
Throughout history there have been many changes, discoveries and invention around the world. One of the more important inventions that changed the world completely was Johannes Gutenberg’s printing press. It’s many great consequences reshaped the world. The printing press was an amazing invention that became so extraordinary that it was used to print almost anything such as religious books, advertisements, and even literary works…
Atomic Theory The atom is the smallest unit of an element. It is composed of two main parts. The nucleus is the central point of an atom. Compacted in that small space are neutrons and protons that constantly jiggle.…
An atom is a basic unit of an element. For thousands of years, people have been questioning about these tiny particles and have came up with many theories based around it. Though many people believe atomic theories started with John Dalton around the late 1700s or early 1800s. This is not true as the atomic theories started sometime during 300 or 400 B.C. with the philosopher, Democritus, being one of the first to come up with a theory about atoms. Democritus’ theory gave the basics of an atom; but his theory was rejected by many during his time as fellow philosophers, Aristotle and Plato, rejected his theory ("The History of the Atom").…
