Why this lab studies the speed of bug pee and other curiosities

This section introduces the overarching philosophy of Dr. Saad Bhamla, a bioengineer at the University of Colorado Boulder, who emphasizes curiosity and the joy of exploring natural phenomena. It discusses how his lab's diverse projects—from studying the hydrodynamics of insect pee to designing squid-like robots—are interconnected by a simple drive to uncover nature's secrets. The narrative highlights his approach of serendipitous exploration and the importance of asking interesting questions.

Here, the discussion delves into Dr. Bhamla’s fascinating research on the speed of droplets ejected by insects and the concept of 'super propulsion.' Using high-speed videos and physics principles, his team discovered that surface tension acts like a spring, storing energy and boosting droplet speed. This adaptation conserves energy for the insect that feeds on water-rich xylem, aiding its survival. The research exemplifies how biological systems optimize energy use through clever physicochemical mechanisms.

This section explores Bhamla's emerging research on music, particularly how playing compositions backward reveals differences in how our brains perceive harmony and melody. Using a vast database of music from different eras and cultures, his team analyzes how the laws of thermodynamics and statistical physics might explain universal patterns in music and neural appreciation. This interdisciplinary inquiry aims to understand if there are fundamental laws behind musical harmony and temporal encoding.

In this part, Bhamla discusses his rejection of traditional academic constraints and his belief in working across disciplines. He shares how self-permission, risk-taking, and curiosity are crucial for scientific discovery. He emphasizes that science should not be limited by rigid rules, and that following what excites and intrigues us leads to more meaningful insights, ultimately benefiting society and inspiring innovation.

Bhamla reflects on how losing his mother at a young age shaped his worldview, fostering a sense of wonder and appreciation for life's puzzles. His experiences in Madagascar, witnessing and participating in natural explorations, catalyzed his childlike curiosity into a professional pursuit. He advocates for embracing curiosity at any stage of life, highlighting how personal hardships can enhance one’s capacity to see the world anew.

This section provides insights into Bhamla’s criteria for choosing meaningful research questions. He likens good questions to art—poetry, painting, or music—that evoke deep emotional or intellectual reactions. A good scientific question, he explains, is one that sparks joy, curiosity, and a feeling of discovering something unique. It should inspire a continuing journey of exploration, where the scientist feels a sense of uncovering secrets that have never been revealed before.
