10 STEM TikTokers to follow in 2023

Short-form video content is a great way to discover new science and technical topics. Check out these STEM influencers on TikTok.

Short-form videos have topped the popularity charts. These videos are snackable content -- short, snappy and easily accessible with minimal production costs.

Short-form videos have many uses, including marketing, live-streaming, tutorials or just for fun. And they're found on many social media platforms, including Facebook, Instagram and YouTube. But the most popular social channel is TikTok.

TikTok -- owned by ByteDance -- was launched in China in September 2016. Since then, it has grown exponentially and currently has more than 1.677 billion users, according a Demand Sage report. TikTok offers its users the opportunity to create and engage with short-form video content. These bite-sized videos can range from 10 seconds to three minutes in length.

But TikTok isn't all marketing and comedy sketches -- it is also a tool for education. TikTok created a new feed specifically dedicated to science, technology, engineering and mathematics (STEM) in 2023, giving users the opportunity to refine their feed in a granular way. To date, STEM-related hashtags have received more than 110 billion views. Here are some of the top STEM TikTokers to follow.
