Different use of air laser and new battery Abstract: This report included the compare and contrast of two new technology in the Assessment Event 2. It started as the definition of human progress, which is a development of the society. By comparing and contrasting the ultra-low-power digital memory and air laser, it is hypothesized that the ultra-low-power digital memory is more important than air laser. Finally, because it could stimulate the develop of economy, help the invention of other fittings and solve the environmental problem, so the ultra-low-power digital memory is better than air laser. Introduction: The human progress is an indefinite development that pushed forward by technology, biology and sociology. Every important invention or finding found by human, the human progress pushed forward. In general, if human behavior was changed, such as when the airplane was introduced to people for a new transportation which saved their time, it is said that this kind of invention led to human progress. Thus, it is defined that human progress is the development of the society, including the economy, political, scientific advance and form of living. With the time goes by, the development of science could not follow the needs of human for their daily use, and new technology appear quickly in current situation. This study included two of them: the ultra-low-power digital memory, and the air laser. These technologies are being applied by scientists for modern devices. Thus, it helped human progress move forward. It is hypothesized that the ultra-low-power digital memory is more important than air laser, because it could affect human progress deeper in peoples daily life by saving energy, helping growth of economy and improving more inventions on other fields. Methods: The purpose of this study is to find out which of the new technology benefits the human progress most. 1. Give the definition of the human progress. 2. Pick up two cases in the Assessment Event 2. 3. Compare and contrast these two cases and list them in the given chart. 4. According to the characteristics of two cases, form a hypothesis to which one benefits the human progress in a deeper way. 5. Research the advantages online for the one to support the hypothesis. 6. Using the resources to write the report, including the result, discussion and conclusion. Results: The first case examined is a new technology that could help for an extension for the battery of mobile devises. Its scientific advance is that the batteries will be extended longer, which means there will have an economic way for human to use batteries. And this technique could address the huge consumption of power, especially electricity. It addresses the problem by using ultra-low-power digital memory, because it uses less energy. The report talked about this new technology published by the team, which was led by Professor Eric Pop, in University of Illinois in 2011. In the current situation, people use a memory that is similar to ultra-low-power digital memory, but it consumes 100 times more energy than the new. This invention could benefit things that use battery for power supply. The second case examined is the advance about laser, which could stimulate the oxygen atoms in the air to high energy level. Its scientific advance is that the laser could detect bomb for human. And it addresses the problem of the flaw that old remote laser-sensing method just can reflect or scatter outgoing beam. It addresses problem by letting the oxygen in the air be excited to high energy level, then fall the atoms then back with infrared light to stimulate more atoms fall. This was discovered by Arthur Dogariu and other engineers in Princeton University in 2011. The current technique is remote laser-sensing method. In the future, this could detect not only the bombs, but also the contaminations, and it might be used with radar to detect remote things. Figure 1: The diagram shows the differences and similarities between Ultra-low-Power digital memory and air laser. Although they belong to the same field in science, they have many differ about their applications to human life. Ultra-low-Power digital memory is supported by the nanoscale, which could help it to eliminate energy consumption. Air laser enables the transformation of remote laser-sensing methods, and it provides greater
