We all interact with electromagnetism on a daily basis.  Life would be rather difficult without it.


The unification of electric and magnetic phenomena in a complete mathematical theory was the achievement of the Scottish physicist Maxwell (1850's). In a set of four elegant equations, Maxwell formalized the relationship between electric and magnetic fields. In addition, he showed that a linear magnetic and electric field can be self-reinforcing and must move at a particular velocity, the speed of light. Thus, he concluded that light is energy carried in the form of opposite but supporting electric and magnetic fields in the shape of waves, i.e. self-propagating electromagnetic waves.


  • Maxwell's new theory provides a new description of light, as electromagnetic waves
  • electromagnetism represents a sharp change in the way Nature is described, i.e. the use of invisible fields and understanding that can only be communicated with mathematics
[size=-1]In doing this, Maxwell moved physics to a new realm of understanding. By using field theory as the core to electromagnetism, we have moved beyond a Newtonian worldview where objects change by direct contact and into a theory that uses invisible fields. This introduces a type of understanding which can only be described with a type of mathematics that cannot be directly translated into language. In other words, scientists where restricted in talking about electromagnetic phenomenon strictly through the use of a new type of language, one of pure math.[/size]

Maxwell's Equations
Integral form in the absence of magnetic or polarizable media:
I. Gauss' law for electricity
Gauss' law for electricity


II. Gauss' law for magnetism
Gauss' law for magnetism
III. Faraday's law of induction
Faraday's law of induction
IV. Ampere's law
Ampere's law

Those are the four allegedly "elegant" equations.  I can recall getting a few headaches from them back in the day.

I don't trust electromagnetism, no sirree.  Just good ol' flame for me.
I'm kinda with you, but along the same lines I think typical home range burners are just too wimpy. 
I want a badass gas range with an integrated wok burner. Something that can put out serious BTUs. 
And whether they're gas or electric (don't care), a double oven. 
In my dream kitchen, it's going to more resemble a restaurant kitchen than a home kitchen. But probably less stainless steel--gotta keep the Mrs happy ;-)

I just want a 10 min pizza oven.  I'd end up putting all sorts of rubbish through it to see what worked well and what didn't.  Maybe some bacon grilled cheese or something.  Hot anything in 10 min.  Yes, please, and thank you...and it would keep the house warm.

I'm using a Wolf now. That thing kicks some serious ass.

https://www.finecooking.com/article/how-an-induction-cooktop-works

 Thus, on an induction cooktop, the heat is coming not from the burner, but the pan itself.  This can make for more efficient cooking–a pot of water will come to a boil on an induction stove in almost half the time of a standard gas stove. You’re also less likely to have hot spots in your pan, where food gets scorched because it has more contact with the heat source below. And, once you remove the pan, an induction cooktop cools off faster than a conventional burner, because it was only hot from contact with the pan.

Dude... Cincy... I love you man. But...

I have a degree in electrical engineering and was a practicing engineer for over a decade. I'm pretty familiar with electromagnetism...

my wimpy electric range top gets plenty hot enough to burn almost anything edible

and I'm a patient man, waiting a few minutes for water to boil doesn't bother me

Wolf is a great product. I think the best high end ranges are from Dacor, personally. Viking is nice looking but quality is garbage. Miele and Gaggenau are great German products- but good luck getting those serviced. If I had 100K to blow on a rage, I'd get a top of the line La Cornue just for the freaking looks. Those babies are GORGEOUS.

Standard ovens you buy for the home are terrible for pizza making. If you want to make real pizza you need to get a Stefano Ferrara oven from Italy.

In my dream kitchen.....
as long as we're dreaming I won't be doing any of the cooking.It'll be made nightly by the ATK crew and I'll be served by a good looking Michigan Grad - I know there's a few out there.I'll be living in an airy Roman-Greco Villa with a mountain spring on one side from which Oktoberfest will be made from all year long.And on the other side will be a volcanic mineral hot springs.I will have a round American wife and she will raise rabbits for our culinary delight

Most gas ranges they sell at Home Depot or Lowes or Best Buy are kinda garbage. Not exactly the best. Hard to find quality when you are buying a gas range for $900. Most of the high end luxury appliance maker ranges are every bit as good as the commercial ones that restaurants buy- the drawback- they are expensive as hell.
