Ep. 5: Students endure a boring quantum theory lecture before investigating the Computer Club's low-tech festival project.
Aired on November 1, 2014

During a school lecture on quantum theory and Schrödinger's cat, the students struggle to stay awake. After classes conclude, members of the Astronomy Club investigate the Computer Club's contribution to the school festival. They discover that the project appears unusually low-tech compared to the club's usual high-tech reputation. The group works together to understand the reasoning behind this simple approach and uncover the true nature of the project. This investigation highlights the contrast between the complex scientific concepts discussed in class and the practical, hands-on activities undertaken by the students outside of school hours.
