PROFESSOR: Since z, that's straight up. And that is going to provide for you a cell that has the shape of a square prism. This would be a1. This would be a2. And this would be a3-- I'm sorry, this would be c. And if you took the choice for the third translation as 1/2 half of a1 plus 1/2 of a2 plus some amount z up above the base of the cell, and then redefined a T3 prime that would be equal to-- sorry. What am I doing here? Yeah. This is right. 1/2 of a1 1/2 of a2, and z straight up. Define a T3 prime as 2T3 minus a1 minus a2. And that will define for you, again, a cell in the shape of a square prism with a1 and a2. And now the translation that went up directly over the center of the base of the net below. Twice that minus a2 minus a1 brings you back to a third translation T3 prime that's normal to the base. So both cells have the same shape. This is a primitive. This is a body-centered tetragonal lattice. And the symbol that's used to represent the body-...

Since you're enrolled in this course, let's assume that you have decided on, or perhaps are already engaged in, a managerial or professional career. And that you are developing, or have already developed the knowledge and skills necessary to do the job. That's great, but don't stop there. Experts agree that it will take a special set of competencies to succeed in tomorrow's organizations, which will be even more globalized, digitized, collaborative, and agile than those we see today. Many have written on this topic. One of the best sources, we think, is a small monograph published by the Institute of the Future, titled, The Future of Work Skills 2020. Here is a brief synopsis of the 10 competencies that the Institute suggests will be essential for your career success and the years ahead. First, relating to globalization. The Institute stresses the need for cross-cultural competency, which has a couple of key components. One is the ability to work effec...
