A TedX event in Arlington this fall will feature nine speakers, including a transgender teen, an 11-year-old YouTube vlogger and the founder of a local nonprofit.

TedXArlington is scheduled from 9 a.m. to 5 p.m. on Oct. 3 at the Rosslyn Spectrum Theatre (1611 N. Kent Street), and tickets are $75. The theme of this year’s conference is “Connectedness.”

“Connectedness means building community through connections and networks. At TEDxArlington, we will explore connectedness from different layered perspectives including family, neighbors, community — even strangers — and from the lens of science, nature, art, technology, culture, history, athletics, work and more,” according to the TedXArlington website.

Each speaker will give a talk or presentation about different topics that all have to do with connectedness.
