In the popular Japanese cartoon ‘Doraemon’, the Dokodemo doa (or everywhere door) can transfer any object instantly. We may think that this is absurd in reality because it violates Einstein’s theory of relativity – nothing can travel faster than light. Chinese physicists, however, discovered recently that quantum entanglement could lead to a breakthrough of this limitation1. They worked on experiments repeatedly and finally proved that quantum entangled particles are able to transfer physical states much faster than light1. Does it mean that travelling superluminally (i.e. faster than light) is possible? Does quantum entanglement break all existing physical laws? What is quantum entanglement? The term ‘quantum entanglement’ may sound highly …show more content…
Although theory suggests that particles remain entangled regardless of their distance, the flaws of instruments such as optical fibers make this impossible in reality3. Chinese physicists and engineers are tackling this obstacle. In 2012, physicists at the University of Science and Technology of China (Shanghai) smashed the quantum teleportation record when they created two separated entangled photons at a distance of 97km successfully3. Since the old record of 16km was also achieved by another group of Chinese physicists7, there is no doubt that the development of quantum teleportation in China will continue to out-perform other countries. Quantum entanglement is a scientific phenomenon that is changing how scientists view well-known existing physical laws. Although the interactions of entangled particles are mysterious, they could turn out to be the key to secure communications. Though it may be disappointing that we cannot travel faster than light using entanglement at the moment, physicists are discovering more and more new, strange physical laws and it is still possible that Einstein’s theory of relativity is ultimately wrong. So, who knows? Maybe we will be able to travel superluminally one day or even have our very own personal Dokodemo
For several years, proponents have spoken of optical storage as a near-future replacement for both hard drives in personal computers and tape backup in mass
Foreign Intelligence Surveillance Act allows U.S. intelligence agencies to acquire foreign intelligence information by monitoring foreign persons in the USA and abroad. This act ensures that intelligence agencies can respond in time to terminate a security threat. The most important part of this act, the Section 702 forbids deliberate monitoring of US citizens and their communication. Technically NSA has been violating this act ever since it has been enacted in 2008 because, as we know, they have been monitoring all US citizenry.
Nuclear energy has numerous world benefits that other forms of energy creation just don’t, and its pros are truly unprecedented by any other source of energy. Nuclear power plants are inexpensive to run, which means they can easily be maintained and sustained at a low cost. And while the reactors themselves may be expensive, with government grants the materials can be much more easily purchased and built. The most expensive part of the nuclear reactor process is the uranium, which again, isn’t hard to get as it’s used in few other applications and can be acquired through government programs. Additionally, the energy emitted from these power plants compared to their cost is immense and an extremely worthwhile investment for governments and private businesses.
The Equal Rights Amendment was passed to eliminate the discrimination on women and men to have equal rights throughout the United States. Political campaign and politicians were trying to go against voters from supporting the Equal Rights Amendment but Phyllis Schlafly attracted the attention of the nation and she points out that equality of rights under the law should not be denied by the United States or by any state because of gender. People agree with her because she believes equality of rights would eliminate laws that protected women and if the amendment became law they will lose preferential treatment in child custody, legally be subject to the draft and might get less pay from child support. Phyllis says, “why do we have to lower ourselves
One principle in particular that is being contradicted is the conservation of energy. If non-physical properties are capable of interacting with and having an impact on the physical world, that would mean that there was an external source of energy used to make the interactions occur. An additional source of energy would violate the law of conservation of energy in physical science, which states that energy cannot be created nor destroyed (Urone). I am aware of arguments that may arise from discussion of different physical laws, specifically conservation of energy, such as: Do Subjective things require energy to occur or is it only needed to create physical processes and objective things? Even though there is no satisfactory answer at this point in time, it is important to note that it is possible that the non-physical properties of physical processes may arise from a distribution of the objective material’s energy.
America is the only industrialized nation not using the metric system. There are only other two countries that still are not using the metric, which are Burma and Liberia. That means out of the 196 countries in the world, only 3 countries including the US are still using the Imperial system. Both Burma and Liberia are some of the poorest countries in the world and, are considered developing countries. While neither of these countries are officially declared metric, they use this as their majority.
However, it still didn’t explain how information was escaping from the black holes, as the information would remain whole even in the 2D world. Marolf, another person working with such concepts, showed that regardless of string theory, every model of quantum
The security is overriding to improve the nation, now day security is increasing to control the terrorism. NSA Surveillance one of the agencies that provide intelligent records to the American government. Although leaking out personal information making the American uncomfortable and people started getting freak out. “I am not trying to bring down the NSA, I am working to improve the NSA. I am still working for the NSA right now.
Entrapment is used by officers to persuade and lure suspicious civilians to commit a crime that they have not been proven guilty of. This article talks about entrapment and explains positives and negatives of they system. The article focuses on the holes and unclear frame work in the entrapment tactic. Entrapment is a useful tactic in catching suspicious criminals before they commit a crime that could possible hurt someone. This is a good and efficient tactic for officers, it keeps the innocent safe.
Introduction Psychological research and its findings have profound impact on people, relationships, and institutions in our society (Willig, 2013). However, as any other study, psychological researchers are faced with enormous limitations including inappropriate designs or methodologies due inadequacy of professionals (Wang, et al., 2015), geographical differences that impacts on generalizations (Smith, 2015), and time pressure that negatively affects the quality of a research (Punch, et al., 2014). Language barrier and lack of literature or poorly done review are other factors that affect psychological research (Willig, 2013). Limitations Limited number of professionals in the psychological research is one of the key limitations to this field of study. Psychological research depends on observations, experimentation, and evidence, hence the need for critical methodological designs (Shipman, 2014).
Cryptography is a technique or method to secure personal data from unauthorized user. In cryptography two types of operation are performed. (i) Encryption and (ii) Decryption. To encrypt and decrypt data a secret key is used. After encryption original data is converted into another format known as cyphertext, which is not easy to understand.
Socrates’s allegory of the cave in Plato’s Republic Book VII is an accurate depiction of how people can be blinded by what they are only allowed to see. The allegory does have relevance to our modern world. In fact, all of us as a species are still in the “cave” no matter how intelligent or enlightened we think we have become. In Plato’s Republic Book VII, Socrates depicts the scenario in a cave where there are prisoners who are fixed only being able to look at the shadows on the wall which are projections of things passing between them and the light source.
People claim that nowadays they are living in surveillance society because Big Brother in twenty first century is keeping a close eye on people’s daily life. If so what is the meaning of Big Brother? The word Big Brother first introduced in George Orwell’s book named 1984. He said that “Big Brother is Watching You. ”(George Orwell, published year).

Credibility: For my informative speech, I have conducted extensive research on the scientific contributions of Albert Einstein. e. Thesis Statement: People view Einstein work as just if he has only contributed a few things to sciences and physics, but he did a greater amount then the majority of people know. Preview of major points: In this speech, I will show you
Did you know that only happy people are allowed in space? It is because you cannot cry on space as your tears will never fall… Wait, there is more… Did you know that there is a huge reservoir of water that is floating and orbiting in space, and which is the equivalent to about 140 trillion times all the water in the earth’s oceans and seas? Did you know that in 1962, the United States blew up a Hydrogen Bomb in space that was close to hundred times stronger than the Atom Bomb they dropped in Hiroshima?
