Star Math – Time, Part 2

Everything is constantly in motion, even at the smallest level. The world rotates and revolves, and time marches on, whether we’re watching or not. And usually, we’re not. The best way to start paying attention to time, is by observing the sun. Please don’t stare directly into the sun, that’s an A+ Bad Idea. If …

Star Math – Introduction to Time

What does time have to do with anything? I keep talking about time and speed, without actually tackling what significance they have. Time itself, and how a person experiences time is a HUGE topic that I won’t dive all the way into. It gets very philosophical. For our purposes, we’re interested more in timekeeping. How …

Star Math – A Sense of Direction

“That does it! Now, I’m going to take your sense of duty, your sense of proportion, and especially your sense of direction!” – Senses Taker, The Phantom Tollbooth (movie, 1970) You know, I have always understood that compasses point generally Northward, or that East is in the direction of sunrise, but… I never really knew …

Star Math – North

Hello. If you’re new to Star Math, welcome! We’ve just been chatting about finding your way around this big, beautiful world of ours. And it’s not just about finding your way, but about feeling secure in where you are, and the journey you’re going on. Last time we explored the direction circle, or what degrees …

Star Math – Where Am I?

If you’ve never read Norton Juster’s The Phantom Tollbooth, it’s full of unexpected life truths. Essentially, Milo, a little boy bored with life, blithely embarks on an adventure where he meets extraordinary people and creatures. At one point, he encounters Alec, a boy that was born in the air and grows from his adult height …

New mini-series! Star Math

Due to a mysterious construction project, I am unable to get out to the site I’ve been mapping. So I decided to kick off a small navigation series in the meantime! I will be focusing on celestial navigation, a topic that I will be learning right along with you, as well as exploring some natural …

Mapping the Reserve, Day 4

Conditions have not been great for conducting a survey, heat smoke, and now the local peoples are carrying out some sort of construction project. But it’s been a great time to get some practice in, sighting horizontal distances! There’s some math involved, but it’s actually very simple and requires only one formula. Using an astrolabe …

Mapping the Reserve, Day 3

That’s right! One of the reasons why maps looked so wild in the medieval era, is that science was sort of on pause. The gaps in knowledge were often filled with reports from sailors or whatever the cartographer could imagine a place would look like. Even toward the end of the century, when measurement tools …

The Math

I know. I’m supposed to be making a new astrolabe. And I will! I may not need it just yet, if I can grab some bamboo poles… but we’ll get back to that next time. I was running calculations though, and wondered… what was running calculations like in the 15th century? This was the end …

Mapping the Reserve, Day 2

Day 2 became days 3, 4, 5… I’ve learned a lot about this tiny patch of green over the past few weeks! There seems to be a weird Bermuda Triangle situation going on with part of the trail. All of my compasses go wacky, and I have to start over. Furthermore, since I can’t pin …
