Editor’s Selections: Fat Rectangles, Big Halos, and Estimating Time and Numbers

Editor's Selections 10 Comments
By Sarah Kendrew

Sarah Kendrew Sarah Kendrew selects interesting and notable ResearchBlogging.org posts in the physical sciences, chemistry, engineering, computer science, geosciences and mathematics. She blogs about astronomy at One Small Step.

On NanoExplanations, Aaron Sterling talks at length about the problem of rectangulation of orthogonal polygons, or: calculating fat rectangles, and why we should care. I’m pleased to report that I learnt something new today – thanks Aaron.

Galaxies that are actively forming stars, report astrophysicists, are surrounded by more substantial and oxygen-rich halos. Charles Daney gives a nice discussion of this work on Today’s Science.

Our level of maths wizardry is apparently linked to how good we are at estimating times. On Inkfish, Elizabeth describes a very interesting study that shows a correlation between the two skills.

Thanks for the great writing this week, and I’ll be back next Monday with more selections!
