What Is A Diagram?

This question comes up in search queries for my blog often. Most readers will already know the answer to this, but since so many do not, I am going to answer it in an extra post. I am also going to refer you to other posts connected to it.

In case you wound up on this post without reading the title, the question is: "What is a diagram?" A diagram is a simple picture that helps to understand ideas more easily. That is my own definition of a diagram. I am going to give you a link to a dictionary definition of it also. I hope that you will be able to look up any words you don't understand after you read this. I have posts on how to use the internet to look things up. You might want to read those also.

Here is a dictionary definition in red:

[dahy-uh-gram] Show IPA noun, verb, di·a·gramed or di·a·grammed, di·a·gram·ing or di·a·gram·ming.
a figure, usually consisting of a line drawing, made to accompany and illustrate a geometrical theorem, mathematical demonstration, etc.
a drawing or plan that outlines and explains the parts, operation, etc., of something: a diagram of an engine.
a chart, plan, or scheme.
verb (used with object)
to represent by a diagram; make a diagram of.

1610–20;  < Latin diagramma  < Greek:  that which is marked out by lines. See dia-, -gram1

The definition above comes from this link:

You can use the dictionary or others online to look up other words you don't know. You can type the word you want to find out about into your search engine or browser with "def" after it (short for definition) and you will usually get a lot of different dictionaries with their version of the definition. I think it is good to try different dictionaries to see which ones you like the best.

I believe that the most important diagram among my posts on this blog is about what happens when a nuclear bomb explodes. My diagram is not that great, but it gives you some idea of what happens when a nuclear weapon explodes and makes it easier for readers to think about it. This makes it possible to make a plan to live through a nuclear war. I do not care what side anyone is on who reads this information. I think it will be hard to keep enough people alive to save the human race after a nuclear war starts, so the more people who live, the better.

Any survivors will be so busy trying to stay alive, that continuing a nuclear war will not be a priority. I think we will need all of the genetic diversity we can get. We certainly won't have enough people left to kill off more after a nuclear war. I hope that a few more people will do emergency preparedness, including for nuclear war because of my blog.

I have other diagrams on my blog for things like a cheap, easy-to-make solar oven and for a rocket stove that is basically a fancy hole in the ground, but takes very little fuel. If you look at these diagrams and study them a little, you will be able to take the ideas and make your own versions of a solar oven or a rocket stove with the materials you have available. I put lots of links into my posts to help you understand and use the information in my posts.

I started this blog as a public service to as much of the world as possible, to help more people live and thrive in spite of the damage that humans have done to the Earth. 

I believe that people are capable of behaving much better than we have so far and hope that this blog and all of its posts will help us to become better humans. First, we have to stay alive.
