Although it does an excellent job of presenting the essentialelements of each topic, it seems that it had been “written by committee.” Notation is inconsistent(“h” stands for either enthalpy or film coefficient, “Q” represents volumetric flow rate or heat,etc.). There are several topics for which the text does not provide the desired coverage(turbomachinery, numerical methods, Reynolds transport theorem, combustion, etc.); since thethree texts used previously were issued by the same publisher as the TFSE text, permission wasobtained for specific chapters from the three texts to be used in conjunction with the newcurriculum.

field which resulted in this. By seeing both the manifestation of a specified vector fieldand its associated equation, students were able to gain greater insight into the relationshipbetween the equations, operations, and manifestations of the fields they had been studying.Electromagnetics One daunting task for most students is to take an equation for a phenomenon and tellwhat it “means” or what it “does.” This is especially true in the area of electromagnetics, whereMaxwell’s equations have befuddled generations of students. Take for instance the equation forthe electrostatic field due to a point charge: r r r r q r -r

transfer coefficient for a horizontal fin. This estimatedvalue is in close agreement with values of the average heat transfer coefficient that have been foundfrom the experimental temperatures.Despite the relatively simple analytical model proposed, the actual physical situation is rather com-plicated. Effects such as (1) currents in the air which indicate forced (or mixed) convection, (2) aninteraction between the flow around the mounting plate and the fin, and (3) radiative heat transferbetween the mounting plate and the fin warrant additional consideration.References 1.

WinIQSIM does not provide flexibility to add additional modules to theblock diagram (as does Simulink and SystemView); but the real advantage to instruction is thatconcepts can be readily demonstrated without students having to perform any programming. Assuch, the author views this package as extremely powerful for undergraduate instruction.WinIQSIM is available as a free download through the Rohde & Schwarz website8.

then present two ways ofconsidering capacitors. First, we present the physical model as a device that stores charge, anddraw the corresponding analogy from hydraulics (water stored in a tank or bucket). We then givea more abstract definition that a capacitor is a device that obeys the equation V = qC, and drawthe parallel to Ohm's law, (i.e., the R in Ohm’s law is replaced by C, and I by its integral q).Next the students construct a simple low-pass filter. Each team uses different RC time constants,and all teams use the function generator and oscilloscope to find the 3 dB point and the generalshape of the response curve of the circuit. Again, the teams swap data and plot the performanceof the circuits. The process is repeated for the high-pass

time required the students to understand and apply (through exercise problems), anempirical densification rate equation to the literature data.Further analysis of the data of Fig. 1 would be useful for students majoring in Materials scienceand engineering. For example, the role of thermal activation during sintering can be revealedmore clearly in an Arrhenius plot of the experimental data as natural logarithm of the densityversus inverse temperature (Fig. 3). Two distinct linear regimes, each consistent with a formalArrhenius-type relationship (i.e., d = d0.exp [-Q/RT], with d and d0 being the density at atemperature T and at room temperature, respectively) can be identified in Fig. 3 over differenttemperature ranges.

Of math educators, she asks: “that we encourage our students to look for hidden assumptions and make them explicit…[w]e must teach them to expect a standpoint in any scientific statement and include it as part of their observations…[i]n mathematics, we should include more open- ended problems that require one to make assumptions in order to solve them.
