The ultimate aim is to give students a thorough understanding of the basic concepts of physics in all its aspects, from mechanics to modern physics. A second objective is to show students how useful physics is in their own everyday lives and in their future professions by means of interesting applications to biology, medicine, architecture, and more.
1. MCQs are there at the end of each Chapter. They are not the usual type. These are
called MisConceptual Questions because the responses (a, b, c, d, etc.) are intended to
include common student misconceptions.
2. Search and Learn Problems at the very end of each Chapter, after the other Problems.
Some are pretty hard, others are fairly easy. They are intended to encourage students to
go back and reread some part or parts of the text, and in this search for an answer they
will hopefully learn moreif only because they have to read some material again.
3. Chapter-Opening Questions (COQ) that start each Chapter, a sort of stimulant. Each is
multiple choice, with responses including common misconceptionsto get
preconceived notions out on the table right at the start.
4. Digital. Biggest of all. Crucial new applications. Today we are surrounded by digital
electronics. How does it work? If you try to find out, say on the Internet, you wont find
much physics: you may find shallow hand-waving with no real content, or some heavy
jargon whose basis might take months or years to understand. So, for the first time,
tried to explain:
The basis of digital in bits and bytes, how analog gets transformed into digital,
sampling rate, bit depth, quantization error, compression, noise (Section 1710).
How digital TV works, including how each pixel is addressed for each frame, data
stream, refresh rate (Section 1711).
Semiconductor computer memory, DRAM, and flash (Section 218).
Digital cameras and sensorsrevised and expanded Section 251.
New semiconductor physics, some of which is used in digital devices, including LED
and OLEDhow they work and what their uses areplus more on transistors
(MOSFET), chips, and technology generation as in 22-nm technology (Sections 299,
5. New topics, new applications, principal revisions.
You can measure the Earths radius (Section 17).
Improved graphical analysis of linear motion (Section 28).
Planets (how first seen), heliocentric, geocentric (Section 58).
The Moons orbit around the Earth: its phases and periods with diagram (Section 59).
Explanation of lake level change when large rock thrown from boat (Example 1011).
Biology and medicine, including:
Blood measurements (flow, sugar)Chapters 10, 12, 14, 19, 20, 21;
Trees help offset CO2 buildupChapter 15;
Pulse oximeterChapter 29;
Proton therapyChapter 31;
Radon exposure calculationChapter 31;
Cell phone use and brainChapter 31.
Colors as seen underwater (Section 244).
Soap film sequence of colors explained (Section 248).
Solar sails (Section 226).
Lots on sports.
Symmetrymore emphasis and using italics or boldface to make visible.
Flat screens (Sections 1711, 2411).
Free-electron theory of metals, Fermi gas, Fermi level. New Section 296.
Semiconductor devicesnew details on diodes, LEDs, OLEDs, solar cells, compound
semiconductors, diode lasers, MOSFET transistors, chips, 22-nm technology (Sections
299, 10, 11).
Cross section (Chapter 31).
11. This Book is Shorter than other complete full-service books at this level. Shorter
explanations are easier to understand and more likely to be read.
12. Cosmological Revolution:With generous help from top experts in the field, readers
have the latest results.
