作为一门实验科学，物理学利用科学的方法来制定和检验基于观察自然世界的假设。物理学的目标是利用这些实验的结果来制定科学定律，通常用数学语言来表达，然后可以用来预测其他现象。当你谈论理论物理时，你指的是物理学领域，它专注于发展这些定律，并利用它们来推断出新的预测。理论物理学家的这些预测随后产生了新的问题，实验物理学家随后开发实验来测试。这样，物理学（和一般科学）的理论和实验组成部分相互影响，相互推动，发展新的知识领域。物理学在其他科学领域中的作用，从更广泛的意义上说，物理学是自然科学中最基本的。例如，化学可以看作是物理学的复杂应用，因为它着重于化学系统中能量和物质的相互作用。我们也知道，生物学的核心是化学性质在生物上的应用，这意味着它最终也是受物理定律支配的。当然，我们不认为这些其他领域是物理学的一部分。当我们科学地研究某件事情时，我们会在最合适的尺度上寻找模式。虽然每个生物的行为方式基本上是由其组成粒子所驱动的，但是试图用基本粒子的行为来解释整个生态系统，将陷入无益的细节层次。甚至在研究液体的行为时，我们通常通过流体动力学来研究流体的整体特性，而不是特别注意单个颗粒的行为。因为物理学涵盖了如此多的领域，所以它被分成几个特定的研究领域，例如电子学、量子物理学、天文学和生物物理学。物理学包括天文学研究，在很多方面，天文学是人类第一个有组织的科学领域。古人看了看星星，认出了星星的图案，然后开始利用数学的精确度根据这些图案来预测天堂会发生什么。无论这些具体的预测有什么缺陷，试图理解未知的方法都是值得的。试图了解未知仍然是人类生活中的一个中心问题。尽管我们在科学技术上有所进步，做人意味着你能够理解一些事情，也有一些事情你不能理解。科学教给你一种方法去接近未知事物，并且问一些问题去了解未知事物的核心以及如何让未知事物为人所知。物理学，尤其是关注于我们的物理宇宙的一些最基本的问题。基本上，唯一可以问的更基本的问题属于“形而上学”的哲学范畴（字面意思是“超越物理学”），但问题是，这些问题太基础了，以至于形而上学领域的许多问题甚至历经几个世纪或几千年的历史，大多数历史上最伟大的思想。另一方面，物理学已经解决了许多基本问题，尽管这些解决方法倾向于提出全新的问题。更多关于这个问题，看看我们的文章“为什么学习物理？”以及“科学的伟大理念”（经许可，改编自《为什么科学》一书？James Trefil）
澳大利亚莫纳什大学物理学Essay代写:实验科学
As an experimental science, physics uses scientific methods to formulate and test hypotheses based on observing the natural world. The goal of physics is to use the results of these experiments to formulate scientific laws, usually expressed in mathematical language, which can then be used to predict other phenomena. When you talk about theoretical physics, you mean the field of physics, which focuses on developing these laws and using them to infer new predictions. These predictions by theoretical physicists subsequently created new problems, and experimental physicists subsequently developed experiments to test them. In this way, the theoretical and experimental components of physics (and general science) interact and promote each other to develop new areas of knowledge. The Role of Physics in Other Sciences. In a broader sense, physics is the most basic in natural science. For example, chemistry can be regarded as a complex application of physics, because it focuses on the interaction between energy and matter in chemical systems. We also know that the core of biology is the application of chemical properties in biology, which means that it is ultimately governed by the laws of physics. Of course, we don’t think these other fields are part of physics. When we study something scientifically, we look for patterns on the most appropriate scale. Although the behavior of each organism is basically driven by its constituent particles, trying to explain the whole ecosystem with the behavior of basic particles will fall into useless levels of detail. Even when we study the behavior of liquids, we usually study the overall characteristics of fluids through hydrodynamics, rather than paying special attention to the behavior of individual particles. Because physics covers so many fields, it is divided into several specific research fields, such as electronics, quantum physics, astronomy and biophysics. Physics includes astronomy. In many ways, astronomy is the first organized field of science. The ancients looked at the stars, recognized their patterns, and then began to use mathematical accuracy to predict what would happen in heaven. Whatever the flaws of these specific predictions, it is worthwhile to try to understand the unknown. Trying to understand the unknown is still a central issue in human life. Although we have made some progress in science and technology, being human means that you can understand some things, but there are also some things you can not understand. Science teaches you a way to approach the unknown, and asks questions about the core of the unknown and how to make the unknown known known known. Physics, in particular, focuses on some of the most fundamental problems of our physical universe. Basically, the only more basic questions that can be asked belong to the philosophical category of “metaphysics” (literally “beyond physics”), but the problem is that these questions are so basic that many questions in the field of metaphysics have even gone through centuries or thousands of years of history, and most of the greatest thoughts in history. Think. On the other hand, physics has solved many basic problems, although these solutions tend to raise new ones.
