Finding the Pattern.

I love graphs, plots and charts. There is something almost magical about their ability to ask a question, analyze it and make a point all in one place.

I think that's why I love to visualize data. I love how powerful the perfect graph can be by allowing you to quickly and deeply grasp a concept (especially for large data sets) by telling a story and using the eye to draw your attention to the right places. Our minds are great at seeing trends and patterns in data when it is visualized.

Effect of Room Correction on Home Theater Performance.

Introduction
Is room correction worth it? Additional processing introduces new artifacts. But it also corrects others caused by room modes and reflections. I think a (somewhat) quantitative look at the numbers will help answer this question.

So what does room correction address?

  • Amplitude response over frequency (frequency response) caused by room modes and speaker/system defects
  • Transient response caused by room reflections or phase distortion in drive electronics and speakers

And what does it introduce?

Similarities.

I am almost all the way through Ken Burn's "Vietnam". I've watched every episode twice and I am blown away at how visceral, gritty and real it feels from my couch. And it has changed me.

Big Bang Reality Check.

I was reflecting on some recent ideas about the "human centric" understanding of our universe. Our minds and bodies are naturally designed to work within a certain size of objects, quantities, spaces and within human perception. And for everything outside that space we scale things to fit our understanding.

Calculus: Differential Equations (Part 5 of 5)

Preface
This series is aimed at providing tools for an electrical engineer to analyze data and solve problems in design. The focus is on applying calculus to equations or physical systems.

Introduction
This article will cover differential equations using Laplace Transforms.

There is no reference book for this entry.

This also assumes you are familiar with Python or can stumble your way through it.

Calculus: Integrals (Part 4 of 5)

Preface
This series is aimed at providing tools for an electrical engineer to analyze data and solve problems in design. The focus is on applying calculus to equations or physical systems.

Introduction
This article will cover integrals.

There are many calculus references, the one I like to use is Calculus by Larson, Edwards and Hostetler.

This also assumes you are familiar with Python or can stumble your way through it.

Multi Party System

The American 2 party system is long due for a replacement. Something that allows voice, change and something other than the words "Democrat" and "Republican" which essentially have become fairly vague and meaningless.

But I love enjoy the drama and the process of electing US Presidents. I don't consider it a handicap that we have a long time to get to know the candidates.

But I have thought of a system that would fix our election system while keeping the best parts. As it turns out it is almost exactly like the European systems I've seen:
