What do the “buzz” words “embedded systems” and “macrofab” refer to. Isn’t it all electronics and computer programming? Why do engineers come up with these words that only seem to intimidate and scare way learners?

They aren't there to scare anyone. They're just words, like the ones we use to communicate here.

Every field has its own "jargon - special words or expressions used by a profession or group that are difficult for others to understand." While difficult to understand for outsiders, it doesn't stop anyone from doing a little research. For example, if you feel intimidated by those words, why don't you look them up? They are, after all, 'buzz' words as you point out and so there is likely to be a lot of information there.

How do I apply math to electronics?

Is Ham radio dead?

It sounds like amateur radio operators know a lot about electronics.

The internet seems to be making radio and satellite technology obsolete.

not at all. Amateur radio will always be a key communications backup in emergencies. Additionally many amateur radio operators do it for the enjoyment of understanding and operating radio, and for the enjoyment of talking with people via equipment owned and operated only by each other.

My dad was an amateur radio operator. He certainly didn't do it for the lively conversation. Most of the folks he spoke to were unpleasant. If I had to guess why he did I'd say it was a compulsion to collect every DX cards (postcards you'd get from someone you talked to on radio as a sort of proof) from every country on Earth. Once he accomplished that his interest quickly waned.

I can tell you this... being an amateur radio operator in a suburban neighborhood is a great way to make enemies of all your neighbors. The entire neighborhood would complain that his radio was ruining tv reception. He'd say ohhhh you all just have to install RF chokes on the line from your rooftop aerial and folks would look at him as if he were speaking Swahili. I'm quite surprised the FCC never stepped in and enforced that his sidelobes were below interference levels.

Didn't make keeping friends very easy when everyone blamed you for lousy tv reception.

Is being able to code just as good as applying math to electronics?

My company is down-sizing their hardware groups because there’s no new hardware coming in, or plans to manufacture any.

And they’re moving hardware guys to the software teams to learn software and agile development?

What’s happening?

Is being able to write software and program just as good as, or better than, applying math to electronics?

It depends what you're doing, but it is a very useful skill. When I was studying for my PhD in physics, all of us at the department had to learn how to write computer programs because modern science pretty much requires it. If you're an electrical engineer, I would say you're probably in a similar situation.

Team reshuffles in companies happen from time to time, especially small companies. We all have to adapt to keep what we are doing relevant to our aims. In the case of companies, the aim is to make money and you can't do that without adapting to the markets or changing your practices so you can keep developing products that customers want to buy. Another aim could be that, as a company, managers want to improve the existing situation somehow, e.g. by having better teams, better productivity, higher quality outcomes, happier workforce, etc.

If a strategic decision has been made to focus more on software rather than hardware, then only time will tell if the decision pays off. People also get to learn new skills and start doing something different. Some people like that kind of thing (like me... I hate doing the same thing over and over again), some people don't (I know people who are happy doing what they are doing and don't want to change).

It's just a different skill which can be very useful, depending on what you are doing. I wouldn't be anxious about it. After all, mathematics is often calculated using computer programs.

I like to think of it a bit like this:


Problem -> Model -> Method/Solver -> Solution

- The problem is the thing you want to solve
- The model is the description of your problem in some specific, organised framework
- The method/solver is a technique that allows the problem to be solved
- The solution is the outcome of the problem


So... let's say your problem is "how to calculate the current at all points in a circuit".

Your model will be the circuit model... resistors, wires, batteries, etc. It will also describe their parameters (such as voltage, resistance, length of wire, etc.) and also the set of mathematics that links things together, like Kirchoff's laws. This is where most of your mathematics, engineering and physics knowledge comes in handy.

Your method/solver is the technique that solves the model. This involves, for example, solving sets of equations using linear algebra and/or other numerical methods. It could be done by hand, using pen and paper, a device (like a calculator) or a computer program. You could, for example, write a computer program that solves the set of linear equations described by Kirchoff's laws, using the Gaussian decomposition method or perhaps LU-decomposition and back-substitution method. There's all sorts of ways of calculating problems.

The solution is the result of your technique; numbers, diagrams, graphs or other outcomes. You might draw the diagrams by hand after looking at the numbers on a computer screen, import them into Excel and make tables, graphs and charts or write a computer program to post-process the data and generate tables and figures for publications.

I hope this helps!
