Part of what we are going to do this week is to be sure we understand measurement and scale. This will help when we are looking at fractal dimension.
For some inspiration, we have
- One of my favorite educational videos of all time, Powers of Ten, by Charles and Ray Eames.
- And since I can’t resist Vi Hart, we have this video of Vi and Sal of Khan Academy talking about how we think of scale.
Tools for working with measurement and scaling:
- This calculator will let you scale up or scale down. It works with conversions of the form, e.g. 2:3. The “scale down” converter will allow you to take real life measurements and convert them to measurements in drawings. The “scale up” converter will do the opposite — let you go from a drawing to real life. If you know, for instance, that you need a 3/4 scale, then you can enter this as 3:4. Then if you are going from the larger version to the smaller use the “scale up” (or use scale down if going from smaller to larger).
- SpectraRuler is an iPhone app that lets you do measurements of height and width, even of objects you cannot reach.
- The Human Proportion Calculator can help you find accurate proportions for drawings of a variety of body measurements. You can enter age, gender, and type of units you want to use.
- I’ll post more as I find them!
