This is the third followup of the blog article: “A perfect storm in a cup of salt water?”I woke up last night with a perfect explanation for the mysterious temperature gradient observed in a saturated salt solution. It is the recrystallization of salt …
This is the second followup of an earlier blog article “A perfect storm in a cup of salt water?”I did an experiment to investigate the relationship of the salt concentration with the mysterious temperature gradient in a cup of salt water. The experimen…
This is the first followup of the blog article last week “A perfect storm in a cup of salt water?”.Several people including Bob Tinker, John Loosmann, and Einar Berg suggested that it was the evaporation of water that drives the observed persisting tem…
Andy Zucker’s article, “Transforming Schools with Technology,” was featured in Independent School magazine. The special issue, focused on the theme of Teaching in a 2.0 World, won an award from the Association of Educational Publishers as the best single-theme issue of an education publication.
The new issue of @Concord includes articles on formative assessments in electronics, a new simulation for teaching and learning heat transfer, nanoscience and genetics education, and more.
