How well scientists and engineers present their work affects whether their ideas are accepted. In turn, these presentations affect the careers of these science and engineering presenters. Sadly, many scientists and engineers follow the weak defaults of Microsoft PowerPoint and build their presentations on topic-phrase headlines supported by bulleted lists. This web-site advocates an assertion-evidence approach (AE approach), which builds presentations on messages and supports those messages with visual evidence. This AE approach leads to presentations that are better comprehended, remembered, and believed.
