Recommended: Heisenberg's Uncertainty Principle
The Heisenberg Uncertainty Principle is a fundamental concept in quantum mechanics that paved the road to understanding many uncertainties in the ability of an observer to measure more than one variable simultaneously. The Uncertainty Principle refers to the fact that the accuracy in one measurement, within some range of certainty, comes at the cost of accuracy in another measurement (Rohrlich 147-51). Not all experimental values are uncertain because we can determine “x” and “y” precisely, just not at the same time. It is, therefore, incorrect to summarize the Heisenberg Uncertainty Principle saying, “everything is uncertain.” It is wrong to summarize Heisenberg’s Uncertainty Principle by stating, “everything is uncertain” because accurate experimental measurements are possible, even at the sub-atomic level. For example, a particle’s position can be detected very precisely with light of a certain wavelength. Using shorter wavelengths improves the accuracy of the position measurement, but such waves carry more energy that will disturb the particle’s energy. This prevents us from establishing the particle’s momentum upon detection. The disturbance of the particle cannot be avoided with better experimental technique considering that any matter or energy based instrument will influence the particle being measured. One could argue, that the initial particle velocity could be back-calculated, so both parameters could be known simultaneously. Yet, this only determines past that are not useful for present conditions or future predictions. Thus, Heisenberg did not suggest that all measurements are uncertain, rather he demonstrated that making a measurement of one parameter fundamentally changes another property of the object such that... ... middle of paper ... ...r dreamlike illusion (Frenkel). In summary, it is incorrect to summary Heisenberg’s Uncertainty Principle as, “everything is uncertain” for several reasons. Heisenberg did not imply that all measurements are uncertain, rather he demonstrated that making a measurement of one parameter fundamentally changes another property of the object such that the two parameters can never be known at once. While many physical properties can only be described in terms of probabilities, this ever-present uncertainty is not a consequence of the Heisenberg’s Uncertainty Principle.

...hes. In Alice and Quantumland, the principles or concepts of quantum mechanics are compared with the macro world; one can find great similarities and even greater dissimilarities between the world wherein electrons rule, and the world wherein human beings live. The author, Robert Gilmore, creates an allegory based off the principles of quantum mechanics using the original story of Alice in Wonderland. Through Alice’s adventure in Quantumland she comes across some ideas or features that contradict real world ideas. These ideas are the following: Electrons have no distinguishing spin, the Pauli Exclusion Principle, Superposition, Heisenberg Uncertainty Principle, and . All of these features are comprised essentially of the same universal concept--that the quantum world does not require definity whereas the macro world uses it as a pillar of society and civilization.
In the second meditation of Descartes, he continues his topic about doubt and certainty. And he doubts that nothing is certain and wanted to use the Archimedes’s methods – “Demand just one firm and immovable point in order to shift the entire earth.” (Descartes, p394) - to make something certain. And the starting point is to find at least one thing that he can assure is “certain and unshakeable” (Descartes, p354).
The relationship between certainty and doubt has been a heavily debated topic throughout history and especially in the mid-1800s. For most people, having some doubt on one’s opinions is much more beneficial than having absolute certainty because doubt allows one to review his potential choice and leaves room for him to make improvements on his choice. Someone who lives with absolute certainty cannot weigh the pros and cons because he has the confidence that what he believes is the right decision for everyone; however, there are situations in one’s life where absolute certainty is necessary, such as in team sports. With the exception of competitions, however, it is more important for one to have doubt in his or her life because doubt allows

The author tells of how waves are effected by quantum mechanic. He also discusses the fact that electromagnetic radiation, or photons, are actually particles and waves. He continues to discuss how matter particles are also matter, but because of their h bar, is so small, the effects are not seen. Green concludes the quantum mechanics discussion by talking about the uncertainty principle.Chapter 5: The need for a New Theory: General Relativity vs.
This Essay is meant to shed light on a complex subject, quantum entanglement. Now, quantum entanglement is a part of much more complex subjects, such as classical mechanics, quantum theory, and quantum mechanics; these subjects will not be covered. The idea of quantum entanglement will be explained: What it is and when does it happen. After a little understanding of Entanglement, a discussion will follow on what it means for us from a technological standpoint and what can we accomplish in the near future. Pushing that idea further into the future looking at bigger possibilities in transportation, and what potential liabilities and moral dilemmas could ensue. It is my belief that quantum entanglement could accomplish many great things, but could
Determinism is the theory that everything is caused by antecedent conditions, and such things cannot be other than how they are. Though no theory concerning this issue has been entirely successful, many theories present alternatives as to how it can be approached. Two of the most basic metaphysical theories concerning freedom and determinism are soft determinism and hard determinism.
Certainty: The Certainty is defined as the state of being without doubt of one’s belief which can shape people thoughts, decisions, attitudes, and behaviors.
However, by making the assumption that all statements are universally either “true” or “false”, he dismisses perfectly logical scientific explanations which are merely outdated. Specifically, he is saying that explanations that were previously accepted by the scientific community but are no longer due to “ampler evidence now available...was not-and had never been-a correct explanation” (138). This is simply not true, as the “correctness” of an explanation is not binary; that is, there may exist some explanations which provide partial explanations which may be perfectly accurate in some contexts, but misleading or even wrong in others. I will refer to this as the context dependency of scientific laws. A good example of such a phenomenon with more than one correct explanation is how electricity is produced. Electricity can be explained as the motion of electrons, which are subatomic particles that circulate around the nucleus of an atom. The Bohr model gives this explanation, claiming that an atom looks akin to our solar system. Recently, more accurate models like the Schroedinger model have come through to state that the Bohr model is not entirely accurate, and that the existence of electrons around atoms in certain places is based on probabilistic models. Despite this new information, the Bohr model can still be used to explain electricity and the motion of
Since its inception, science relied on predictability and order. The true beauty of science was its uncanny ability to find patterns and regularity in seemingly random systems. For centuries the human mind as easily grasped and mastered the concepts of linearity. Physics illustrated the magnificent order to which the natural world obeyed. If there is a God he is indeed mathematical. Until the 19th century Physics explained the processes of the natural world successfully, for the most part. There were still many facets of the universe that were an enigma to physicists. Mathematicians could indeed illustrate patterns in nature but there were many aspects of Mother Nature that remained a mystery to Physicists and Mathematicians alike. Mathematics is an integral part of physics. It provides an order and a guide to thinking; it shows the relationship between many physical phenomenons. The error in mathematics until that point was linearity. “Clouds are not spheres, mountains are not cones, bark is not smooth, nor does lightning travel in a straight line.” - Benoit Mandlebrot. Was it not beyond reason that a process, which is dictated by that regularity, could master a world that shows almost no predictability whatsoever? A new science and a new kind of mathematics were developed that could show the universe’s idiosyncrasies. This new amalgam of mathematics and physics takes the order of linearity and shows how it relates to the unpredictability of the world around us. It is called Chaos Theory.
Of the many counter intuitive quirks of quantum mechanics, the strangest quirk is perhaps the notion of quantum entanglement. Very roughly, quantum entanglement a phenomenon where the state of a large system cannot be described by the state of the smaller systems that compose it. On the standard metaphysical interpretation of quantum entanglement, this is taken to show that there exists emergent properties1. If this standard interpretation is correct, it seems that physics paints a far different picture of the world then commonsense leads one to believe.
Moritz Schlick believed the all important attempts at establishing a theory of knowledge grow out of the doubt of the certainty of human knowledge. This problem originates in the wish for absolute certainty. A very important idea is the concept of "protocol statements", which are "...statements which express the facts with absolute simplicity, without any moulding, alteration, or addition, in whose elaboration every science consists, and which precede all knowing, every judgment regarding the world." (1) It makes no sense to speak of uncertain facts, only assertions and our knowledge can be uncertain. If we succeed therefore in expressing the raw facts in protocol statements without any contamination, these appear to be the absolutely indubitable starting points of all knowledge. They are again abandoned, but they constitute a firm basis "...to which all our cognitions owe whatever validity they may possess." (2) Math is stated indirectly into protocol statements which are resolved into definite protocol statements which one could formulate exactly, in principle, but with tremendous effort. Knowledge in life and science in some sense begins with confirmation of facts, and the protocol statements stand at the beginning of science. In the event that protocol statements would be distinguished by definite logical properties, structure, position in the system of science, and one would be confronted with the task of actually specifying these properties. We fin...
“How can we understand the world in which we find ourselves?” In The Grand Design, a 2010 book written by theoretical physicist Stephen Hawking and Leonard Mlodinow, two authors claim that they have found a philosophical approach – Model Dependent Realism (MDR) – as the solution to this fundamental question of philosophy. Combining the ideas raised from methodology of mathematics and Physics, MDR leads a possible path to reconcile the uncertain nature of modern science and the idealistic pursuit of absolute truth – perhaps the theory of everything (TOE).
The Merriam-Webster Dictionary definition for certainty is “known or proved to be true”. But can something ever truly be certain? . There is always something that could occur that could derail something from happening. However, there is sometimes a sense of certainty that one has, and this sense, whether true or false, can create a strong feeling of confidence in someone or something. An aspect of certainty that is commonly overlooked is that in certain situations, thinking something is certain can inspire hope in someone. This notion of having confidence can play a unique role on one’s mind and thought process. A feeling of certainty can inspire hope in someone, believing that something is set in stone, and this feeling acts as a driving force in the attitude of that one person. Another important way in which certainty can affect someone is through someone’s decision-making. When something, usually a situation, is seen as “certain”, this feeling can bring about a gargantuan deal of confidence, and confidence is also a very influential force. Confidence often kickstarts someone, lighting a fire beneath them, and driving them to reach their goal or
