Martin Luther King Essay Essays - Community Organizing, Free Essays All people should be treated equally no matter what color skin they have, people deserve to have a chance of a bright future in a world that treats people equally. The importance of the I Have a Dream' speech by Rev. Dr. Martin Luther King, Jr. is that this speech portrayed the importance of equality between people and a man's passion of building a better world for the future generations. This essay shows that through passion and dedication you can accomplish anything. The I have a Dream' speech by Rev. Dr. Martin Luther King, Jr. changed the government into what we now live in. It changed so that segregation ended and people where equal. People weren't insulted by the color of their skin but on the personality of the person. It showed the government that all men had rights of life, liberty, and the pursuit of happiness. Rev. Dr. Martin Luther King, Jr. wanted to be granted civil rights for African Americans in a peaceful manner than through physical violence. Through this dedication and passion people are now treated with the same chance at success in life within a society who accepts them all equally. Rev. Dr. Martin Luther King, Jr.'s speech is important today because without those civil rights many people wouldn't have jobs because of the color of their skin. People wouldn't have the same opportunities as those with civil rights. African Americans wouldn't be able to contribute to society and help make the world a better place. We wouldn't have our first African American president. African Americans wouldn't be able to describe on character because of their skin color. African Americans wouldn't be able to be associated with white people. Everyone deserves to be treated with equal respect and rights. This is important in my life because we do have an African American president. African Americans have contributed to society and have been given the opportunity to make the world a better place. I have African American friends who are outstanding people who are dedicated hard workers. In the future I will be able to work with African Americans and be treated with equal rights. It proves that through the dedication of a few it can affect the future of many. Life is about rights and being treated equally. People are able to have the same opportunities as others and they show society that the government has done the right thin in providing them with civil rights in order to allow everyone a fair chance of success in life. In conclusion, the world is treating everyone with equal respect and dignity no matter what race or skin color they have society accepts everyone. No matter what people say it is within he rights of the government that all people should be treated equally and fairly between each other in a society who will accept them for who they are no matter what their skin color is. That is the importance of the I Have a Dream' Speech.

Facts about the Importance of Graphene

Facts about the Importance of Graphene Graphene is a two-dimensional honeycomb arrangement of carbon atoms that is revolutionizing technology. Its discovery was so significant that it earned Russian scientists Andre Geim and Konstantin Novoselov 2010 Nobel Prize in Physics. Here are some reasons why graphene is important. It Is a Two-Dimensional Material. Nearly every material that we encounter is three-dimensional. We are only just beginning to understand how the properties of a material are changed when it is made into a two-dimensional array. The characteristics of graphene are very different from those of graphite, which is the corresponding three-dimensional arrangement of carbon. Studying graphene helps us to predict how other materials might behave in two-dimensional form. Graphene Has the Best Electrical Conductivity of Any Material. Electricity flows very quickly through the simple honeycomb sheet. Most conductors we encounter are metals, yet graphene is based on carbon, a nonmetal. This allows for the  development of electricity to flow under conditions where we might not want a metal. What conditions would those be? We are only just beginning to answer that question! Graphene Can Be Used to Make Very Small Devices. Graphene conducts so much electricity in so small a space that it may be used to develop miniaturized super-fast computers and transistors. These devices should require a minuscule amount of power to support them. Graphene is flexible, strong and transparent, too. Opens Research into Relativistic Quantum Mechanics. Graphene can be used to test the predictions of quantum electrodynamics. This is a new area of research  since it hasnt been easy to find a material that displays Dirac particles. The best part is, graphene isnt some exotic material. Its something anyone can make! Graphene Facts The word graphene refers to a single-layer sheet of hexagonally-arranged carbon atoms. If the graphene is in another arrangement, its usually specified. For example, bilayer graphene and multilayer graphene are other forms the material can take.Just like diamond or graphite, graphene is an allotrope of carbon. Specifically, it is made of  sp2 bonded carbon atoms that have a molecule bond length of 0.142 nm between atoms.Three of graphenes most useful properties are that it is extremely strong (100 to 300 times stronger than steel), its conductive (best-known conductor of heat at room temperature, with an electrical current density 6 order of magnitude higher than copper), and its flexible.Graphene is the thinnest and lightest material known. A 1-square-meter sheet of graphene weighs a mere 0.0077 grams, yet is capable of supporting up to four kilograms of weight.A sheet of graphene is naturally transparent. Potential Uses of Graphene Scientists are only just beginning to explore the many possible uses of graphene. Some of the technology under development includes: Ultra-fast charging of batteries.Collection of radioactive waste for easier clean-up.Faster flash memory.Stronger and better-balanced tools and sporting equipment, such as  tennis racquets.Ultra-thin touchscreens  that can be pasted onto a non-breakable material.Graphene-based e-paper that can update with new information.Quick and efficient biosensor devices 200, to measure blood glucose, cholesterol, and possibly your DNAHeadphones with  phenomenal frequency response.Supercapacitors  that essentially make batteries obsolete.Novel waterproof coatings.Bendable batteries.Stronger and lighter aircraft and armor.Aiding tissue regeneration.Purifying salt water into drinking water.Bionic devices that can connect directly to your bodys neurons.
