Student Colloquium: Bubbles and Beyond: The Hidden Physics in Soap and Water, v/ Arkan Tariku Tadesse
Supervisor: Brian Julsgaard
Bubbles and Beyond: The Hidden Physics in Soap and Water” explores the captivating world of soap bubbles through the lens of fundamental physics. This presentation delves into the science behind why bubbles form and take their characteristic spherical shape, showcasing how surface tension and the properties of soap molecules contribute to their creation. Attendees will also learn about the vibrant, ever-changing colors of bubbles, explained through the concept of thin-film interference. The session further investigates the factors leading to bubble bursts, the role of the Marangoni effect, and how bubble lifespans can be extended. Real-world applications of bubbles in science and technology, such as bubble rafts in atomic structure studies and innovations in microfluidics, will highlight the practical importance of these phenomena. By the end, participants will appreciate how everyday bubbles reveal profound scientific principles, turning simple observations into moments of discovery.
