物理学是对自然界的系统研究，特别是物质与能量之间的相互作用。这是一门试图通过精确应用观察与逻辑和理性相结合来量化现实的学科。为了利用这样的学科，你必须首先了解某些基本原理。只有通过学习物理基础知识，你才能在此基础上进一步深入了解这一科学领域。无论您是从事物理学的职业生涯还是仅仅对其研究结果感兴趣，了解它当然是非常有趣的。要开始物理学的研究，首先必须了解物理学的实际意义。了解属于物理领域的内容 – 以及什么不是 – 有助于集中研究领域，以便您可以制定有意义的物理问题。物理学中的每个问题背后都有四个非常重要的术语：假设，模型，理论和法律。物理学可以是实验的也可以是理论的在实验物理学中，物理学家使用诸如科学方法之类的技术来解决科学问题，以试图证明一个假设。理论物理学通常更具概念性，因为物理学家专注于发展科学定律，例如量子力学理论。这两种形式的物理学相互关联，并与其他形式的科学研究相关联。通常，实验物理学将测试理论物理学的假设。物理学家自身可以专注于各种领域，从天文学和天体物理学到数学物理学和纳米技术。物理学也在其他科学领域发挥作用，如化学和生物学。物理学的目标是开发物理现实的精确模型。最好的情况是制定一系列非常基本的规则来描述这些模型的运作方式。这些规则在成功使用多年后经常被称为“法律”。物理学很复杂，但它确实从根本上依赖于许多公认的自然法则。有些是科学领域的历史性和开创性发现。这些包括艾萨克·牛顿爵士的重力法以及他的三个运动定律。阿尔伯特爱因斯坦的相对论和热力学定律也属于这一类。现代物理学正在建立那些巨大的真理来研究诸如探索无形宇宙的量子物理学之类的东西。同样，粒子物理学试图理解宇宙中物质的最小部分。在这个领域，像夸克，玻色子，强子和轻子这样的奇怪词语进入了今天成为头条新闻的科学对话。
Physics is a systematic study of the natural world, particularly the interaction between matter and energy. It is a discipline that attempts to quantify reality through a precise application of observation coupled with logic and reason. In order to make use of such a discipline, you must first understand certain fundamentals. Only by learning the basics of physics can you build upon it and dive deeper into this field of science. Whether you are pursuing a career in physics or merely interested in its findings, it certainly is fascinating to learn about. To begin the study of physics, you must first understand what physics actually means. Understanding what falls within the realm of physics—and what does not—helps focus the field of study so you can formulate meaningful physics questions. Behind every question in physics lies four very important terms you will want to understand: hypothesis, model, theory and law. Physics can be either experimental or theoretical. In experimental physics, physicists address a scientific problem using techniques such as the scientific method in an attempt to prove a hypothesis. Theoretical physics is often more conceptual in that physicists are focused on developing scientific laws, such as the theory of quantum mechanics. These two forms of physics are related to each other and connected to other forms of scientific study. Quite often, experimental physics will test the hypotheses of theoretical physics. Physicists themselves can specialize in a variety of fields, from astronomy and astrophysics to mathematical physics and nanotechnology. Physics also plays a role in other fields of science, such as chemistry and biology. The goal of physics is to develop precise models of physical reality. The best case scenario is to develop a series of very fundamental rules to describe how these models function. These rules are frequently called “laws” after they have been used successfully for many years. Physics is complicated, but it does fundamentally rely on a number of accepted laws of nature. Some are historical and groundbreaking discoveries in science. These include Sir Isaac Newton’s Law of Gravity as well as his Three Laws of Motion. Albert Einstein’s Theory of Relativity and the laws of thermodynamics also fall into this category. Modern physics is building off those monumental truths to study things such as quantum physics which explores the invisible universe. Similarly, particle physics seeks to understand the smallest bits of matter in the universe. This is the field where strange words like quarks, bosons, hadrons, and leptons enter the scientific dialogue that makes headlines today.
