In this episode Dave talks to three science communicators with YouTube Channels. Jacklyn Duff's videos focus on science and technology on her SciJoy channel. Jade Tan-Holmes is an Australian whose Up and Atom videos focus on physics, math and computer science. Sheryl Hosler, aka The Roving Naturalist, loves to share her passion for environmental science. All three came to the same conclusion — that communicating their passion for science was a stronger calling than the traditional research pathway. And they may become regular contributors as special correspondents on future episodes as Blue Dot widens its horizons.
