The Cassandra Dispatch is newsletter and blog. The simple idea is that I send selected videos of extraordinary science communicators like Carl Sagan, Richard Dawkins, Stephen Fry, Richard Feynman and others to you, my subscriber. Currently, I try to send a new issue twice a month. The Cassandra Dispatch is free of charge.


Today, a basic understanding of natural sciences is important. It’s required to better grasp major issues like climate change. If people have a good sense for science, they can make better decisions in their daily lives, how they vote, and how they spend their money. Luckily, there are amazing science communicators like Carl Sagan, Richard Feynman or Richard Dawkins out there. My goal with The Cassandra Dispatch is to share this knowledge more broadly. In the hope, of course, that this will get more people excited about and interested in natural sciences.

Who is Cassandra?

In Greek mythology, Cassandra was a Trojan priestess damned by the god Apollo with the power to tell true prophecies but to be never believed. Many public science communicators use science to foresee important events such as anthropogenic climate change, but like Cassandra, they are often not believed by many people.

Who am I?

My name is Can Olcer, and I’m a software engineer. I’m not a scientist, but I’m very interested in science and spend hours each week reading and watching heroes of mine such as Carl Sagan. I want to share my joy for science with as many people as possible. You can find me on Twitter and Mastodon, or just email me at canolcer@hey.com.
