新西兰留学生论文代写:建立事实的条件

理论也是建立事实的必要条件。一个例子是,理论家们已经预测了希格斯玻色子的存在,而希格斯玻色子是50多年前粒子物理学标准模型中的一种粒子,它鼓励实验物理学家们去寻找希格斯粒子。现在希格斯玻色子的存在已经成为事实。另一个例子是,引力理论早在宇宙飞船和宇航员证实月球和其他行星活动之前就预测了它们的行为。在前两个例子中,这些理论帮助缩小了从广泛的实验和研究中发现的事实范围,使之缩小到提供很少的简单规则来总结数百个观察结果的范围。这些规则使得科学家们有一个研究的重点。几个世纪以来,一些理论一直被人们所认可和接受,这些理论对新的有说服力的理论产生了巨大的影响。以数学为例,推导一个理论并不需要从我们周围的环境中收集任何客观的事实来证明它是正确的。从某种意义上说,数学是真实的,不涉及现实。纯粹的分析陈述可以被先验地证明。定理的证明不能用实验或其他观察到的证据来支持科学理论。在前两个例子中,理论中的变量是可以直接观察到的,这使得理论对未来做出了明确的预测。

新西兰留学生论文代写:建立事实的条件

Theories are also necessary for facts to be established. An example of this is that theorists had predicted the existence of the Higgs boson which is a particle in the Standard Model of particle physics for more than five decades ago[4], which then encouraged the experimental physicists to search for the Higgs. And now the existence of the Higgs has been established as a fact. Another example is that the theory of gravitation predicted the behavior of objects on the moon and other planets long before the activities of spacecraft and astronauts confirmed them. In the previous two examples, the theories helped narrow facts that are found from a wide range of experiment and researches to a narrower scope providing few simple rules that summarize hundreds of observations. These rules make scientists have a focused area of research to examine.Some theories that have been regarded and accepted for centuries had a great impact on the new compelling theories supported by facts but can a theory supersede and replace the need for data and testing? Deducing a theory in mathematics for example does not require any objective facts gathered from our surroundings in order for it to be true. In a sense, Mathematics is true without reference to reality. Purely analytic statements can be demonstrated a priori. A proof of a theorem cannot involve experiments or other observed evidence in the same way such evidence is used to support scientific theories. In the previous two examples, the variables in the theories were directly observable which led to the theories making specific, clear predictions about the future.
