I have worked in two industries that hire a lot of ex-military with essentially a high school level of education.

The first is nuclear power. A lot of the people working in the control rooms are from the military, and it is a very high paying and comfy job for someone without a college degree. The other is high skill technician and assemblers in manufacturing.

The things these jobs have in common is they need a strict adherence to rules and procedures, which is something military training makes people well suited to.

I work in high frequency RF (10s to 100s of GHz). You can use mixers[0] to down convert higher frequency signals and make measurements at lower frequencies.

Macronutirent. Basically it means one of either fat, protein or carbohydrate. Many diets will have you set a calorie goal, and then suggest a guideline what percentage of your calorie intake should come from each macronutrient group.

Another great and well sourced guide is 4chans /fit/ sticky[0].

>Thus we loop over each item in the class dict and only append them to the list if they are not callable (i.e. not methods). Pretty slick and it doesn’t require any imports! But there’s an even easier way!

Actually, objects can be callable by implementing the __call__ method. The inspect.ismethod() is the better solution

This looks like a great service that i didn't know about before. Definitely going to be getting one more user. I wish we could use something like this at work.

Since most of this is rather new to me, are there any other great organizational/ basic life services out there? I would be curious to see what other people are using.

Usually you are trying to catch neutrons in a lithium blanket, and using the fission products to extract energy. At least that is what they are doing at ITER. The electromagnetic energy goes back into the plasma and helps with keeping things hot. The energy extraction is one of the biggest challenges with sustained fusion.

For more math oriented challenges (more project euler like), check out the monthly IBM 'I ponder this'. These are usually quite challenging, but the problems are interesting and solutions are posted at the end of the month. http://domino.research.ibm.com/Comm/wwwr_ponder.nsf/pages/in...

Plasma breakdown. The voltage across the gas eventually accelerates electrons fast enough that they can ionize atoms when they collide, and an avalanche occurs creating a plasma and light. Same effect as a neon lamp

Im going to let someone give a better response for some of these, but i will touch on a few.

2) The dot product can be thought of the projection of one vector onto another, or: If i shine a light directly at one vector with the 2nd vector in between, how long will the shadow of the 2nd vector in the system be? Do an image search for dot product to see this, and it will become clear (if you know basic trig) why the equation is ABcos(theta).

The cross product is defined as having a magnitude equal to the area of the parallelogram that the vectors create. So have both vectors start at the same point, and then mirror them to make a parallelogram (see wiki on parallelogram).

4) How are the different? If you take 1-0.9999.... = x, what is x exactly? You can't tell me the difference. This is essentially how limits work.
