#lifeonmars #Astrobiology #Viking Edit: I accidentally swapped the labels for the x and y axes on the graph In this video I repeat the famous "labeled release (LR) experiment" conducted on Mars: https://en.wikipedia.org/wiki/Viking_... Instead of the radioactive C-14 isotope with which the nutrients were tagged and a Geiger counter, I am using a sensitive and true carbon dioxide sensor. The graph in the video shows the logistic function: https://en.wikipedia.org/wiki/Logisti... Verhulst derived his logistic equation to describe the self-limiting growth of a biological population. The equation was rediscovered in 1911 by A. G. McKendrick for the growth of bacteria in broth and experimentally tested using a technique for nonlinear parameter estimation. In his 1977 Christmas Lecture at the Royal Institution, Carl Sagan also demonstrated the experiment:    • Mars after Viking - Carl Sagan's 1977 Chri...   The experiment, as I conducted it, is very suitable as a science project for students.
