In 1931, Samuel Kistler created aerogel, the least dense solid in the world. Known for its ultra lightweight and incredible insulating ability, recent developments have shown aerogel’s potential in a wide variety of areas. Recently NASA for has used it to insulate Mars rovers and space suits. In addition to this, its extremely low density was utilized to catch dust particles in space, which would otherwise vaporize if they came in contact with solids at high speeds. Its insulating ability combined with its hygroscopic nature allow it to be very useful in both spacecraft and aircraft maintenance, as they keep ice from forming on the wings of the vehicle. Due to its incredible versatility and ultra lightweight, aerogel is a material of the future that will be utilized heavily in years to come. In the 1930’s Samuel Kistler removed all liquid from a silicon gel to produce an ultra-light material that functioned as an extremely efficient insulator, and named his discovery aerogel. It was initially marketed as an insulator, but due to developments in efficient insulation not being of priority in the 30’s, Aerogel development stalled. In the 1980’s, Aerogel development resumed as energy efficiency became a salient issue in America. (Aerogel Crystal Structure, 2005) Although it was deemed too costly for domestic use as insulation, the development of aerogels for commercial and military use has since taken off. Aerogel is produced by making a gel out of a desired material such as silicon, and replacing the liquid in a gel with a pure solvent. Then, the liquid in the gel is heated and pressurized so that it enters a supercritical state, where it can expand and compress like a gas, but has the density and thermal conductivity of a liquid. (H... ... greatly reduce the weight of planes and other military equipment. (DARPA Awards Aspen Aerogels, 2004) Due to their relatively high cost, the main consumers of aerogels are government agencies and large companies. The incredible capabilities and extreme versatility of aerogels provide a bright future for this technologically advanced material. As space exploration expands, lightweight insulation will be at a premium, and demand for aerogels will grow exponentially. In addition, its applications in the military and environmental uses will keep this material relevant for years to come. I believe that as research and development of aerogels continues, the cost of this material will decline to the point that it will become accessible to the average consumer, and could be used in protective gear or as originally conceived, as a cost efficient insulator for domestic uses.

Assisted suicide Essay

Assisted Suicide In the 1990s, ‘Doctor Death’ Jack Kevorkian invented the first assisted suicide machine  in the world. He was then thrown into prison for 7 years (Pickert). This caught people’s attention  and made them question whether it should be legal to request physician assisted suicide, which is  when someone asks a physician to help him or her terminate his or her life. This topic became  one of the most popular discussions in recent years, but the truth is that it has actually been a  centuries- old debate. For both logical and humanitarian reasons, assisted suicide is not right and  should not be legalize. Is it right for a nation founded on Christianity to allow citizens to choose assisted  suicide? Can a decision that is made by a mentally ill person be treated as a rational decision? Is  the prevention of pain an acceptable circumstance in which to end a life? People still do not have  a widely accepted answer. It is not clear whether physician assisted suicide  is right or wrong. Assisted suicide should not be viewed solely as affecting one life, but should be viewed as a  decision that affects many.  The declaration of independence states that everyone has the right to pursue happiness  In whatever way they choose. Many argue that a decision to kill oneself is a private choice, that  society should not be, and has no right to be concerned. America believes that with its freedom,  people can do almost everything based on their own choices. Physician assisted suicide is also  one of the choices that they can decide. The common argument is that these people are adults  who can make rational and reasonable choices, however many people who request physician  assisted suicide are mentally ill. Of those who attempt suicide but were unsuccessful, less than 4  percent go on to kill themselves in the future, which means that most people changed their mind  after a period of recovery. Psychological evidence shows that those who ask for physician   assisted suicide in order to avoid pain are normally ambivalent, and they  usually attempt to end  their life for other reasons than a settled desire to die. Since assisted suicide has already become  a popular way to end suffering and pain, people who were in the status might feel it is necessary  for them to kill themselves since they have in their mind become a burden to their family and  society. Some would say it is wrong for such an impression to have the power to persuade a  personto end their life due to their weakness and disability. As a Christian nation, America wants a positive and happy image for the country.  American people value the meaning of life, and According to what most of the Christians  believe, God is the one who created life. Then how can people have the right to end something  that they did not even create in the first place? American society does not think assisted suicide  is good as a whole, because assisted suicide is still a self-caused death, which is equal to suicide.  Although there is always a vague line drawn between assisted suicide and attempted  murder. Assisted suicide is the opposite of happiness because it demonstrates  utter depression. It  is clear that American society sees assisted suicide as wrong, because there is a suicide watch  team among the police and counselors at schools who are trained to help and avert suicide. Asking for assisted suicide as a form of pain relief and signing a release form is not acceptable  either. People cannot solve problems by trying to get rid of them. People who stand against  physician-assisted suicide believe that suffering is just a stage of life. And lots of people who  were prevented from assisted suicide will tell you that they all passed that stage successfully,  and they are appreciative that they were stopped from asking for physician-assisted suicide. Assisted suicide also hurts the people who care about those who were asking for a  physician assisted suicide. Patients might get relived from their long suffering and pain but their  family will be hurt from one’s immature decision. The person only thought of their own  feelings and never considered others who are around them and how they feel. Families and loved  ones will be upset about their decision to take their lives in a selfish act. Other evidence that  shows assisted suicide is wrong is the fact that there are always suicide prevention billboards in  communities. This should show the government that people do not want those around them to  commit suicide. People who fight for the right to have physician-assisted suicide argue that assisted  suicide can bring benefits to both patients and society. They believe that people who  choose assisted suicide will die with dignity rather than suffer the pain of illness( O’Steen,  Burke). That they will not let their family and friends suffer anymore by showing their weakness  and sickness. By choosing assisted suicide, patients can also reduce a huge amount of medical  expenses that insurance does not cover. To benefit society, their organs can be donated to save  people’s lives (Humphrey). Doctors and nurses can spend more time on recovering patients  rather than waste time on patients who are assured death, and of course, they still think it is a part  of one’s freedom to be able to choose for himself whether to live or die. Whether it is one’s  rational decision to chose to end their life has always been the center of this debate. Because  with out arguing about one’s free right, those who favor assisted suicide will lose an important  statement. Although there is a ton of evidence showing that physician assisted suicide is not right,  it is a fact that so many people are still in favor to legalize assisted suicide. They believe that  rather than give people hope to live, telling them the truth and offering them an option is more  reasonable. They argued that in some ways, it is humane to give dying people assisted suicide;  society is okay with people helping a sick or dying animal yet people are not okay with letting a  sick and dying patient go. It was said that humans are too selfish to let their loved ones go, even  if death would be a comfort. People who think it is illegal for a physician to offer assisted suicide  are accused of wanting to control other people’s lives. People think that one has his/her own will  about their life that no one is suppose to tell them what they should do and should not do. Especially when their faith to live is completely gone. It was understood as a merciful behavior  for a physician to offer help to end one’s life. A new statement was also brought up to argue in  the favor of legalize assisted suicide. It is that if one can reject medical treatment to prolong life  then why can’t one request treatment to end it? Many people found this statement be reasonable  and useful to support the legalization of physician-assisted suicide.  After centuries’ debating, there is still no certain answer for those questions that are  brought up by the topic of assisted suicide. Two sides are still debating about the benefits and  negative effects of assisted suicide. Still to this day no one is able to convince the either group to  change their views on this topic. In 2006, the US Supreme Court ruled that legalizing assisted  suicide is to be the responsibility of each state respectively. No one can yet predict how long this   topic will still be an argumentative topic for debate, And no one can predict how this issue will  effect human life in the future. But overall, do people really possess the right to kill a life that  was not created by them? It is still a big question that no one has yet given an answer that can  satisfy everyone. Maybe one-day people will find out the right answer and that assisted suicide  will be a new thing that brings benefits to the world. Physician suicide should be banned due to  its negative cause and impaction to society. People who think assisted suicide should be  illegalized because of the value of life to a society is still the majority; ending a life is  not so simple that people should decide to do so on their own.

Chinua Achebe s Things Fall Apart - 883 Words

When we think about a European colonialist world view it is often based on judging a society by two major assumptions. These assumptions are the idea that other societies are filled with violent people without manners, and that their religious practices are a hedonistic affront to their own religion. These assumptions make it easy for European Colonialists to somewhat invade a land, and try to take it over. This practice of invading a foreign country is made even easier by the way European Colonialists dehumanize the native population and convince themselves that they are helping. Chinua Achebe’s book Things Fall Apart attempts to correct these misguided views of African societies by portraying a more complex culture that values peace, and the art of conversation. Achebe also tries to portray the idea that not all European people they come in contact with are aggressive, and misconstrued in their view of the African societies. Achebe tries to show us the value of his society t hrough repeated views into conversations, religious practices, and encounters between people.Ultimately Achebe tries to show us that Africa’s complex cultures deserve more credit than taking up a chapter or two in a European colonialist’s book. This attempt at showing Africa as a complex group of diverse cultures goes directly against everything that European colonizers are working for because it humanizes a society they want to dehumanize.
