物理学家关注的自然现象范围非常广泛，从基本粒子的亚微观世界到宇宙的广阔范围以及宇宙的起源，从最简单的日常活动到最极端的物质行为。能量，温度，距离和时间。物理的定义特征是对基本逻辑的追求-统一并解释我们实验研究的所有不同现象的理论结构。实验本身和同时进行的理论工作都主要是出于这一追求。作为这一追求的副产品，物理学家开创了现代技术赖以生存的许多基本思想。晶体管，激光器以及也许有一天的聚变能等发展都直接来自于物理研究。学生在各个领域都有实习机会，包括在约翰·霍普金斯大学应用物理实验室，NASA，微软，波音，库克
Physicists are concerned with an extremely broad range of natural phenomena, extending from the submicroscopic world of elementary particles to the vast reaches of the cosmos and the origins of the universe, from the simplest of everyday activities to the behavior of matter at the furthest extremes in energy, temperature, distance and time. The defining characteristic of physics is the quest for the underlying logicthe theoretical structure that unifies and explains all the different phenomena that we study experimentally. Both the experiments themselves and the theoretical work that goes on at the same time are motivated primarily by this quest. As a by-product of this quest, physicists have pioneered many of the basic ideas on which our modern technology rests. Such developments as transistors, lasers and perhaps someday fusion energy all come directly from research in physics. Students have internship opportunities in various fields, including at Johns-Hopkins Applied Physics Lab, NASA, Microsoft, Boeing, Cook Nuclear Plant, Fermilab, Jet Propulsion Lab, SETI Institute and Air Force bases.
