What I love about Colgate is that the institution is dedicated to giving all of us—faculty and students alike—opportunities to learn new things. For me, those opportunities have been in three main categories: teaching, research, and professional experiences and travel.

I arrived at Colgate in 1997 and promptly got to teach subjects that I had never studied, from Energy and Sustainability to Statistical Mechanics. (How I earned a physics undergraduate degree without statistical mechanics—in fact, with only one upper-level course in physics—is a story for another time!) It’s absolutely true that you learn best by teaching, and I encourage all our students to get involved in peer tutoring.

My initial research at Colgate used time-domain terahertz spectroscopy to study single-molecule magnets, and I’m currently using this technique to study GHz resonators made from carbon nanotubes. I’ve also had the chance to investigate many other problems that intrigued me. I have ongoing projects to quantify insulation in buildings, make solar trackers appropriate for developing nations, characterize a diffusion demonstration, and study air pollution in Uganda.

I’ve also had opportunities to visit and live in other areas of the world, taking students on two extended study trips to learn about renewable energy in Norway, twice leading semester-long trips to Cardiff, Wales, and spending a year as a Fulbright fellow in Mbarara, Uganda. (See an article I wrote for the Colgate Scene,On the Bright Side”) My new adventure is the position of editor-in-chief of the American Journal of Physics, which is the American Association of Physics Teachers’ journal focusing on university-level physics education.

p. 7 implies that the electrical force is 1038 times stronger than gravity.  For two protons, it’s 1036 times stronger, and for two electrons, it’s closer to 1042 times stronger.  The book is roughly correct for the force between a proton and an electron, such as in a hydrogen molecule.

p. 21 micrometers (mm = 10-6)  --  the unit “m” is missing

p. 38, Fourth line from the bottom of the page: The unit “meganewtons” should be written with a lowercase “m.”  The “M” is capitalized in the symbol “MN” but not when the prefix is spelled out.

p. 44, Section 2.7, first word: Double quotation marks should be used on both sides of “Energy.”

p. 44, Section 2.7, third paragraph. The second and third sentences of this paragraph are paraphrases of each other.

p. 49, Section 2.7. The first instance of the word “their” on the page should be “there.”

p. 58 Problem 2.10 should tell you that the dimensions of frequency are time^(-1). The units are s^(-1).

p. 59 Problem 2.16 can't really be solved without knowing the moment of inertia of the ball. As it rolls up the hill, some of its rotational kinetic energy is changed into translational kinetic energy, changing the final speed. If the ball were sliding on a frictionless surface, then we wouldn't have to worry about the rotational kinetic energy.

p. 70 In the paragraph in the middle of the page, the word “atom” is repeated in “atom of helium atom.”

p. 93 In the first line after Exercise 4, “Eq. 3” should be punctuated as an appositive.

p. 100 In the first sentence after the equation for kV, the word “the” is repeated.

p. 101 Exercise 15 includes its own answer.

p. 103 Exercise 18 should be punctuated as a question.

p. 110 There is a missing space between "are" and "N" on the 6th line up from the bottom of the page.

p. 115 The equation between (9) and (10) should have n_M x M_M on the left-hand side, not n_m x M_m.

p. 119 Equation 13 should have M_M in the denominator, not M.

p. 124 Example 5.5 says that when pressure is held constant, mean free path scales with the square root of T because volume scales as T and velocity scales as the square root of T. But of course, the velocity has nothing to do with the mean free path, so the answer should simply be that the mean free path scales with T.

p. 132 Section 5.5 is immediately followed by section 5.7, with no section 5.6.

p. 166 Problem 5.5(d)(e) ask about electric fields, which are not introduced until the next chapter.

p. 167 Problem 6.9c should refer to part b, not “part 0b.”

p. 179 In the paragraph following Eq. 10, joules are defined as N m s-2 rather than N m or kg m2 s-2.

p. 196 Problem 10 should state that the potential difference is 100 V.

p. 265 Problem 11b does not ask a question; it simply gives information that is needed for part (c).

p. 272 In Problem 26, the second paragraph should say “0.207 g” not “0.207 gm.”

p. 290 Exercise 4 should ask for a graph of the displacement vs. position along the length of the string, not vs. the length of the string.

p. 299 Exercise 13 should state that the displacement is a minimum at a time T/4 later.

p. 308 The next-to-last sentence of the first paragraph of section 10.4 is missing a period.

p. 327 Figure 10.21 refers to Problem 0a instead of Problem 5a.

p. 350 Second sentence under “How Motion Described in One Frame is Described in Another”: “tFo” should be “to”

p. 417 Problem 5b should ask why the current is not zero when V > 0, since in this plot, V represents the voltage applied to the cathode with respect to the anode.  When Vcathode > Vanode, the electrons are slowed down as they travel toward the anode, but some of them still get to the anode (the collector) as long as the voltage is less than Vstop

p. 436 Line 4: place à placed

p. 546 Problem 1a is asking you to draw an “energy level diagram,” not just a “level diagram.”

p. 579 Exercise 2 says “either and even number or a 3” when it should be “either an even number or a 3.”

p. 620: “Photons reflected from the beam splitter must be also be in the B state.”

p. 623: Problem 4b is missing the word "a" in "has a compensating plate."

p. 627: Problem 12b presents a table with impossible results, unless there is an eavesdropper. If the two photons are entangled with parallel polarizations, then when Alice's and Bob's polarizers have the same orientation, they must both make the same measurement (either transmitted or reflected).
