So no one responded to this one, so just wanted to give the answer.

In big-o notation you drop all the terms except for the one of the highest order (the term with the highest exponent).. you do this because the notation is about how things scale to infinity, and as you scale towards infinite only the largest term is significant.

This is the same thing that happens with near and far fields in RF.. the equation that describes the field doesnt make any distinction, its just a long polynomial.. but at close distances (near field) all the terms are significant, so the lower exponent terms are valid, so the near field decays at the rate at which the highest exponent becomes dominant and the lower exponents become insignificant... so near field decays at 1/r^6 while the far-field decays at 1/r^2

@LWFlouisa Havent seen you in years, figured you left the fediverse.. Its wonderful to see you again!

So I was thinking a bit and want to get some input... As you all know QOTO is for anyone in STEM as a professional or with a passion for the topic.

I just had an idea of starting a sister-server, one based on the same principle as QOTO but oriented specifically for students and amateurs as seperate from QOTO, which will remain open to everyone.

This separation can have a few advantages. For starters a new server that will have a new reputation in the fediverse so will have much larger initial reach . But more importantly we can use the main server as sort of a source for mentorship for those on the younger server. I'd like to setup extracurricular servers that might be good to facilitate this and provide learning resources as well as publish more advanced content. Maybe even start a scientific journal or organize a shared blog where all our members can post to as a collective...

I'd love some thoughts.

I offer free tutoring in most college level #STEM courses. Can be online, just random questions, video chat, or even in person.

If anyone needs help learning any STEM topic (even you arent in school), please reach out to me I am always happy to help. If I dont know the subject I can also maybe connect you with someone who does, but I am well versed on most of the basics like #Math, #Biology #statistics #BigData #programming #Chemistry #Medicine #ElectricalEngineering and #RF design.

I want to code #haskell so bad, but even now as I contemplate a green field project I just cant convince myself its a pragmatic decision...

I really need to find siome way to use this amazingly gun language!

Understanding big-O notation is what gave me the revelation to understand why RF far-fields and near-fields exist. Specifically why one occurs over short distances and the other over long.

Anyone can guess what the connection between the two were for me?

I have been told I give some of the most technically challenging interviews most people have ever experienced.. once a lady couldnt answer any of my questions, even the easy ones, and just started crying.. little did she know she got the job because im not looking for people who know the answers, I'm looking for people who ask the right questions to arrive at and understand the answers.

It is weird the things you miss when you are away from home for multiple years... friends aside its really nice to have my handy Fluke 289 DMM back in my hand.

Remember kids, when you post about a subject and someone wants to discuss the nuance of your stance, that is a nazi dog whistle... block them immediately!
