Richard Feynman: Theres Plenty of Room at the Bottom

Richard Feynman: Theres Plenty of Room at the Bottom Describe his perspectives, its major points and its implications. The physicist Richard Feynman given a lecture at American Physical Society on December 29, 1959 named Theres Plenty of Room at the Bottom. This article was very different from the other commonly written topics on physics at that time. These days this lecture is commonly mentioned due to its extraordinary imaginative power. In this article Feynman predicted nanotechnology as an entire innovative field and explained the prosperity of innovatory technology advancements and applications such as very high density data storage media and very tiny mechanical devices would be practicable, with many improvements until ultimately essential physical limits at the atomic scale become applicable (Breitfelder). Feynman asked in his lecture to envisage a smallness contest in which we manage to write on a pinhead. Also he stated the techniques to read and write on pinhead. Feynman also talked about miniaturization of computers which is what exactly happening today; at the time of his lecture compute rs were very big. Feynman measured the opportunity of direct management of individualatomsas an extra powerful form of artificialchemistrythan those used at the time. Feynman considered very interesting implications of a general ability to control substance on an atomic scale. He was mainly concerned in the potential of smallcomputers andmicroscopeswhich could see things very small than is likely withscanning electron microscopes. Before Feynman given this speech there was very limited information of nanotechnology exists as he stated there is lot more research and experiments need to be done. However, he described various aspects of this technology and some practical examples of how to achieve large things at small scale. It includes writing very small text (for example the complete 24 volumes of the Encyclopaedia Britannica on the top of a pin), small computers (such as wire) and swallow the surgeon (very tiny robot which can go inside a person and examine him internally). In this article, Feynman asked some questions (like how do wewritesmall?) and he presented the answers for these questions in very significant manner. As he described there was no standard technique to write on such a small scale but it is not impossible. The article also explained the solution of small scale writing using techniques available to engineers in 1959.It was to turn round the lenses of the electron microscope in order to shrink and to enlarge the particular text. If the source of ions sent through the reverse microscope lenses it could focus to a very tiny dot. He further stated that it’s possible to write with that spot such as we write in a TV cathode ray oscilloscope by leaving diagonally in lines, and doing an adjustment which decides the quantity of material we are going to put as we scan in lines. He further assumed that every bit of the information in all books in a library could hypothetically be transformed to digital information and can be stored like bi ts consisting of elements which can have only a few atoms each. These can be two different shapes to represent 0s and 1s. This would bundle much more information into a smaller space, and according to Feynman the complete contents of the worlds large libraries could fit in somewhat the size of a dust nit. The author also presented the very different opportunity (which is the idea of his friend and graduate studentAlbert Hibbs) of swallowing the doctor,†. This idea involved building a little, swallow able surgical robot. This tiny robot goes inside the blood vessel of a person and can examine the internal problem and do the surgery by itself. One tinier machine can be designed to put permanently inside the body which can assist the poorly functioning of organs. Feynman further discussed how to design such a tiny robot with giving the example of atomic energy plants. The author’s imagination about the computers is very interesting as on one side he wanted to add more functionality to the existing computers, on another point he wanted them to be very small. Feynman stated that if we want to add more abilities to these existing large computers (which are of the size of the room) those new computers could be bigger than the pentagon’s building and some other disadvantages includes power consumption, heat generation, slow speed and too much material required. If speed of computers has to be faster, computers have to be smaller. The author recommended that very small computers could be prepared by fabricating all the required wires and components using chemical techniques, to form a little block consisting all the compulsory electronics. Feynman also said that building useful things could be done at the atomic level, by manipulating individual atoms to arrange them however the engineer or scientist wanted .However, he discussed the problems associated with these changes such as the gravity for these little things is not appreciable. If the sizes go smaller, some of the tools would also require redesigning due to the change in the relative strength of various forces. Even ifgravitywould become inconsequential, surface tension would turn out to be more important. At the end of this article, Feynman gave two challenges and offered a prize of $1000 for the person who can accept and solve it first. These challenges involved the construction of atiny electric motor no larger than 1/64th of an inch square and the second challenge involved the opportunity of making size of letters adequately small so that the entireEncyclopaedia Britannica can be written on the top of a pin. The information from a book page could be written on a surface 1/25,000 smaller in linear scale. In November 1960 William McLellan of Caltech, a meticulous craftsman, achieved the solution of first challenge with a device made by hand using conventional tools and claimed the prize. These days this tiny motor is placed in the corridors of Caltech. The book challenge took longer time; it was achieved just three years before Feynmans death in 1985 by Tom Newman, a graduate student at Stanford University, US, using electron-beam lithography. He scaled down the first paragraph ofâ€Å"A Tale of Two Cities†by 1/25,000, and calmed the second prize from Feynman (Feynman’s fancy†). The field has seen remarkable achievements since then, indeed, most notably the reduction of the area of transistors in microelectronic circuits by more than a factor of 107, or of the space required to store 1 bit of information on a magnetic surface by ≈108. Nanomechanical devices have seen tremendous progress, too, through impressive advances in scanning probe microscopy (Feynman’s fancy†). Works Cited Breitfelder, Kim.

Northern NGOs

In this research paper we look at the involvement of Northern NGOs with the developing countries. They are prime donors of most developing countries programs which are geared towards alleviating the welfare of the masses such as improve health and living condition.Local NGOs have been involved as intermediaries between government and the people.The northern NGOs serve their specific agenda and mandate contrary to what the poor rural urban expect.NORTHERN NGOSNorthern NGOs represented international organizations who are donors to developing countries that are are donors such as World Bank and private agencies. Their relation with the south makes it the subject of this research paper. The relationship with governments and nongovernmental organization with them plays a critical role in understanding their mandates and objectives in helping the population in the rural and urban regions.The urban and rural populace has diverse needs ranging from health, unemployment, education, poverty an d access to other services. In this respect governments have been unable to provide these services to their community in an effective and wider coverage manner. For instance, in South Africa, 30 % of the population are unemployed and for the 20% of the poorest households, 53% ere unemployed (Adato & Haddad 2001, p.1).It is also reported that there is need for job creation in all regions inhabited by the poorest households i.e. urban, metropolitan and rural. Based on these facts the governments of countries in the developing world have focused their programs to alleviate these problems e.g. the welfare of the masses, improve living condition, health and service provision (Li 2005).The programs have achieved different success margins and limitations. Most of government programs are constrained in reaching the people because of bureaucracy, authoritarian rule and high cost of implementation. Since most of the programs are financed by international community (Northern NGOs) and governme nts.For instance, in Indonesia the World Bank has developed social development programs to help them achieve their mandate and objectives. In order to do these, they have used analysis of the needs of the regions to come up with the plan. Due to constraints in working with the government directly they have supported and strengthened the local NGOs and civil society organizations (CSOs) to advance their objectives (Li 2005).The rationale use includes improving transparency in village planning level, conflict resolution and step sponsorship of NGOs. However NGOs have their own limitations such as the leaders use as a vehicle for reformation of social and political life. The World Bank has used neo-liberal system to ensure ‘good governance’ by instituting a competitive process based on administrative and decentralized structures (Li 2005).More so in order for the region to be eligible for support from World Bank it had to proof that it is pro-poor and is supervised by the World Bank team. According to Arya (1999) he explains the role in which NGOs have worked with their government under the funding of donors (government agencies, private agencies and governments). The common objectives for the collaboration include; access to technical resources, gain legitimacy or recognition from the people, obtain appropriate solution and developmental problems, enhance people’s participation and provide   better accountability, transparency and public reform system (Arya   1999).Donors view NGOs as intermediaries or transitory to government links to people and use them to as instruments of improved service delivery and outreach to the government. The donors see their task as completed when NGOs are involved in the project programs with the government. Most private donors do not support or supervise the selection criterion even when there is resistance from the government. However, they can play a key role in establishing mechanism to bring NGOs so that they have a beneficial effect on service delivery, participation and decentralization (Arya 1999).Northern NGOs for the past decade have increased funding to southern NGOs with due to limitation effectiveness of delivery, reforms, cost efficiency, sustainability and participation from the government. DeGabriele (2002), when studying about improvement of community based management projects. He previewed the World Health Organization commitment to provide access to safe and clean water.But from the experiences gathered two challenges emerged; water accessibility could not be achieved with the rate of population growth and the intended improvements to health were not realized within 1980 – 1990 decade. This becomes the redefinition of the concept of community management within water sector. It was realized that water accessibility could only be achieved with participatory role implemented (DeGabriele 2002).AED (1998) elaborates on the participatory approach used to i.e. the par ticipatory learning and Action approach which involves communities to analyze their needs, identify possible solutions and develop, implement and evaluate the plan of action. In contrast NGOs can have negative implication to the poor because they can use them to legitimize their existence, solicit funds and raise their profile for the disadvantage of the poor. Changes in their positive attitude will go way to bring positive results (AED 1998, Kaiser 2000, p. 6).CONCLUSIONNorthern NGOs play critical role in financing development programs to developing countries. They have been involved directly or indirectly with government depending on the nature and intensity of the resources used and the origin of the donor. Most private agencies finance the local NGOs who are viewed as intermediaries or transitory link between the government and people. The donors have used them to enhance their agenda and mandate to ensure good governance of project- programs they agree with the government.

The Benefits of Physical Activity Essay - 920 Words

Studies have shown that one who is physically active has higher chances of living longer. Del Sanden writes in his article on Exercise Statistics, People who engage in physical for 7 hours per week have a 40 percent lower chance of dying early than people who are active for less than 30 minutes a week. This statement is one of the many statements in his article proving the importance of fitness; it has the ability to enhance quality of life. Regular exercise can lower the risk of many diseases, improve the function of the physical body, as well as psychological health. Fitness by definition is the condition of being physically fit and healthy. It does not necessarily mean gym workouts, it means being active. When one is active, the†¦show more content†¦Another disease that is commonly found in the US, but can be prevented by physical activity is Diabetes. Diabetes is a disease when the body does not produce enough insulin making sugar levels very high. However, when muscles are in action they can take the sugar/glucose from the blood without the help of insulin. The amount of physical activity necessary for prevention is minimum and does not take up much time. Research suggests that 2 1/2 hours per week of even leisurely physical activity—like brisk walking—is enough to significantly improve glucose tolerance. By going walking instead of sitting by a television screen, one can prevent a disease like diabetes which requires constant medication. Decisions like taking steps instead of elevator can make a huge difference to ones health. Besides for the aforementioned, being active strengthens the body, making it more reliable. Activity works the bones and muscles, making them able to handle more. Bones are living tissue. Weight-bearing physical activity causes new bone tissue to form, and this makes bones stronger. This kind of physical activity also makes muscles stronger. Bones and muscles both become stronger when muscles push and tug against bones during physical activity. This build up enables the body to carry its own weight, making standing on the feet an effortless activity. Stronger bones helps for better balanceShow MoreRelatedPhysical And Emotional Benefits Of Physical Activity1222 Words   |  5 PagesDespite the physical and emotional benefits of moderate physical activity, most Americans are not getting enough exercise to sustain healthy behavior and reduce their risks of illness.

Autobiographical Literature of the Holocaust - 1641 Words

Jpz777 03/11/2013 Order # 2087935 Literature has always been mankinds greatest medium with which to express the spectrum of human emotion and experience, from the anguish of love lost to the joy of discovery, but the evocative power of the written word can also be used to capture the horrors that men are capable of inflicting on one another. During the Holocaust of World War II, during which the Nazi regime of Germany occupied much of continental Europe and murdered more than 6 million Jews in an industrialized genocide, the personal stories of countless victims were lost forever as entire family lines were obliterated on the order of Adolf Hitler and those pursuing his Final Solution. With a megalomaniacal dictator intent on rewriting the history of the Germanic people, while expunging all evidence of Jewish existence under his dominion, Hitlers Holocaust was designed to inflict not only the physical punishment of torture and death, but also the psychological torment of complete annihilation. In the decade following the fall of the Nazi party, with the world still struggling to comprehend the sheer scope of the atrocities committed behind the walls of Hitlers concentration camps, ghettos, and gas chambers, a pair of Holocaust survivors penned intensely moving autobiographical accounts of their persecution.
