DIY Camera Tag Captures Sperm Whales Communicating in the Deep
Engineer Eric Stackpole’s TED talk argues that exploration often advances through improvised tools built for a specific question, not through polished equipment alone. He recounts how a fragile suction-cup camera tag, assembled from ordinary components in the Azores, recorded a sperm whale’s deep dive, hunting clicks and apparent communication with a second whale. For Stackpole, the footage is evidence that discovery depends on curiosity as much as technology, and that exploration matters for what it lets people experience as well as measure.
