Physics 2048C: A Short IntroductionPhysics 2048C: A Short Introduction

This will be followed by an This will be followed by an introduction to wave motion and introduction to wave motion and thermodynamicsthermodynamics

Newton's laws:Newton's laws:From the Gatorade ad:A. "What makes bodies in motion remain in motion?" B. "What makes what goes up, stay up?" C. "What makes what goes down, get back up?"

One of these statements may be attributed to Newton**The answer is A**

Newton's first law (Law of inertia): A body at rest remains at rest, and a body in motion will remain in motion at a constant velocity unless acted upon by an external force.

Standing the test of timeStanding the test of time•The classical laws of physics, including mechanics and thermodynamics, have been rigorously studied through centuries of experiment.

•This is the so-called "scientific method."•During this course, we will explore many (though by no means all**) of the classical laws of physics using controlled experimental demonstrations.

•We will compare the results with simple mathematically based theoretical principles.

•We will then use these theoretical principles to solve a wide range of problems.

**PHY2049 will introduce you to more of these laws.

What do physicists do?What do physicists do?At the end of the 19th century, A. A. Michelson (very famous physicist) stated that "all of the grand underlying physical principles had been firmly established."Then came two revolutions:•Relativity

concepts of space and time change at large relative velocities

•Quantum mechanicsconcept of matter changes on small length scales

•Classical laws of mechanics break down in these limits, and much remains to be discoveredThese are the things physicists study today through experiment and theory, just as physicists have done through the ages.

Physics, the 21st century, & youPhysics, the 21st century, & youA technological revolutionA technological revolution•20th century microelectronics & the computer revolution•Now we have "nanoscience“ (and molecular sciences)

Devices/molecules which are made up from just a few atoms1 nanometer = 1 meter / 1,000,000,0001 millionth of the diameter of a grain of rice

•Nanoscience is revolutionizing electronic and mechanical engineering, biology, chemistry and medicine

•Physics is playing a larger and larger role in all of these fieldsHowever, before you can tackle these modern subjects, you have to have a fundamental grasp of the underlying classical laws of physics
