NISE Sea Ice Coasters

As part of my job, I see a lot of Earth science data, some of which is delivered to my email inbox daily.  Even though I’m not a geoscientist by training, I often find myself thinking of things to do with our data in my free time.  One such project was to make some coasters displaying the Near Real Time Ice and Snow Extent (NISE) imagery.

The details about how I prototyped and created these coasters after the jump. Continue reading NISE Sea Ice Coasters

That thing that just happened

Doesn’t happen very often – I got sick; with the high fever and everything, so, naturally, getting some updated content didn’t happen here.  Regularly scheduled blog posts will start again tomorrow – apologies for that.

P.S. remind me to get a funny gif of sickness or something for the next time this happens.  If I’m clever I’ll set it to a dead-man’s switch or something so that if I don’t blog it automatically shows up.

Taking a Week Off

Hey all – I have no backlog, and I’ve been doing so much writing for work that I’m a little burned out at the moment.  I’m taking the week to build up a backlog and enjoy the writing I’m doing rather than jumping off the bus on Tuesdays and Thursdays to post something to my blog.  Until next week…

…Have Fun!

Linearly Related Units and Significant Digits

Last week, I made the claim that the significant digits of a measurement are not dependent on the units that you use to measure.  Today, I want to look at this from the point of view of units that are linearly related to each other, and I’m going to start with even more specificity and look only at units that are multiplicatively related (for example, this class excludes Fahrenheit to Celsius conversion) using the rules of significant digits. Continue reading Linearly Related Units and Significant Digits

Are Significant Digits Unit Dependent?

A while back, I had a discussion with our development team about significant figures.  Specifically, the discussion centered around where they were going to go to lunch and when they were going to leave.  Someone piped in with, “Right here, right now,” while another countered, “I wonder how many significant digits you should take for that to actually be true…”  The first dev then stated, “First, you would need some units,” at which point I jumped into the conversation claiming, “Actually, I’m not sure that you do.  Whether you are using AU or attometers, the number of significant digits should be the same.” Continue reading Are Significant Digits Unit Dependent?
