NOVEMBER 2022 I DESIGN007 MAGAZINE 9 way" when learning the laws of physics. Next, Happy Holden describes his brief interaction with Maxwell's equations in college—avoid- ing them, primarily. We have a great article by Douglas Brooks and Johannes Adam that uses physics to help illustrate why vias don't get hot. Columnist Martyn Gaudion discusses how analysis and measurements can help you out of a jam when the laws of physics don't seem to apply. Finally, Tamara Jovanovic brings us an update on today's curriculum, fresh from the halls of academia as she pursues her master's in electrical engineering. We have columns from our regular contribu- tors Barry Olney, Stephen Chavez, Matt Ste- venson, Beth Massey, and Tim Haag, as well as an interview with Joe Clark and Mark Gallant. We also have another article by Anaya Vardya in his DFM101 series. ere's a lot happening in our segment of the industry, with four months of conferences and trade shows coming up. We'll be there, bring- ing you the news you need to know. See you next month. DESIGN007 Andy Shaughnessy is managing editor of Design007 Magazine. He has been covering PCB design for 23 years.

Physics is just one more tool in your toolbox. It can help you understand fields and the properties of the materials, as well as concepts such as how fields affect inductance. Over the past few months, we noticed some- thing: Physics can involve a lot of heavy math, such as Maxwell's equations. But as Eric Boga- tin, who majored in physics, says, designers can learn the fundamentals of physics without necessarily mastering all the math. It might sound counterintuitive, but don't let the math keep you from studying physics. is issue is a great place to start. Here, you will learn why you can't ignore the physics of PCB design, especially as features continue to shrink. Our experts will discuss how the laws of physics (field theory, thermal effects, etc.) relate to solid PCB design practices. We also raise awareness of the need for greater understanding of the laws of physics and dis- cuss a variety of resources related to physics and PCB design. Our interview with Eric Bogatin leads this "ready to rumble" issue. He explains how a knowledge of physics can help designers mas- ter electrical engineering concepts, how these disciplines work together, and why it's so important to avoid letting the math "get in the
