When it comes to giving talks, academics would do well to apply some of the thinking behind them to improve their output by observing how it deviates from the desired one, and making changes to adjust it. I’ve been to a number of conferences lately that had a … Continue reading Feedback Loops for Better Talks

April 29, 2015
By

Wayne Lytle created this video about the Viz-O-Matic that provides lots of tools to make visualization glitzier.
