Allen ★ Posted August 5, 2020 Share #1 Posted August 5, 2020 Does anyone here have the mental capacity to wrap their head around higher math? I’m trying to wrap my head around Maxwell’s equations and holy crap it’s hard. Link to comment Share on other sites More sharing options...

Dottleshead ★ Posted August 5, 2020 Share #4 Posted August 5, 2020 Maxwell's equations are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, and electric circuits. ... Maxwell first used the equations to propose that light is an electromagnetic phenomenon. Link to comment Share on other sites More sharing options...

Dottleshead ★ Posted August 5, 2020 Share #6 Posted August 5, 2020 Remember math is just symbols (variables) that represent something measurable. As daunting as they look, most algebra can be solved following the order of operands. The calculus portions are really just the summations of measurements over time (usually).

Dottleshead ★ Posted August 5, 2020 Share #7 Posted August 5, 2020 It looks to me the only calculus portions are the bottom two equations. And they both measure the change of something over time. Link to comment Share on other sites More sharing options...

Dottleshead ★ Posted August 5, 2020 Share #10 Posted August 5, 2020 This is helpful to understand what these differential equations are. In mathematics, a differential equation is an equation that relates one or more functions and their derivatives. In applications, the functions generally represent physical quantities, the derivatives represent their rates of change, and the differential equation defines a relationship between the two. So in short, a differential equation is the relationship of the rate of change (usually with respect to time) between two or more entities. In other words, how does the rate of change in something effect the rate of change in something else? For example, I get an erection at an increased rate when my wife is naked in the tub based on a few conditions. How does that rate effect the rate of desire in my wife? Is this relationship directly proportional (I wish) to her interests or indirectly proportional (typical -- run for the exits)? 1 Link to comment Share on other sites More sharing options...

I had a training session with my wife just so she didn't squirm on just seeing symbols and gobbledgook. Hmmmm...

12string Posted August 5, 2020 Share #18 Posted August 5, 2020 My daughter has a masters in theoretical math. My son is a computer/electrical engineer who innately understands math better than his sister. His wife has a PhD in physical Chemistry. The 3 of them occasionally will go off on a little discussion about math stuff, and they could be speaking Remulak for all any of the rest of us know. They get all excited, talk about math books they're reading for fun. weird kids. 1 1 1 Link to comment Share on other sites More sharing options...

I’m trying to wrap my head around Maxwell’s equations and holy crap it’s hard. I had to use them a lot when I was taking 200 & 300 level college calculus-based Physics classes and some in upper level (300-600) chemistry classes. I remember that in some instances, you can get away with converting the partial derivatives in the equations into ordinary deltas (changes in), but its been a long time since I had to do anything more complicated with electromagnetism than the right hand solenoid rule to determine which end of the bar is magnetic North.
