David Hu, head of the 2015 Ig Nobel Prize-winning urination-duration-research team, has a new animated video explaining that research:
The 2015 Ig Nobel Prize for physics was awarded to Patricia Yang, David Hu, Jonathan Pham, and Jerome Choo, for testing the biological principle that nearly all mammals empty their bladders in about 21 seconds (plus or minus 13 seconds).
They explain that research in detail, in the study “Duration of Urination Does Not Change With Body Size,” Patricia J. Yang, Jonathan Pham, Jerome Choo, and David L. Hu, Proceedings of the National Academy of Sciences, vol. 111 no. 33, August 19, 2014, pp. 11932–11937.
Patricia Yang and David Hu, together with additional colleagues, were awarded a second Ig Nobel Prize four years later. The 2019 Ig Nobel Prize for physics was awarded to Patricia Yang, Alexander Lee, Miles Chan, Alynn Martin, Ashley Edwards, Scott Carver, and David Hu, for studying how, and why, wombats make cube-shaped poo.
They explain that research in detail, in the study “How Do Wombats Make Cubed Poo?” Patricia J. Yang, Miles Chan, Scott Carver, and David L. Hu, paper presented at the 71st Annual Meeting of the APS Division of Fluid Dynamics, Abstract: E19.0000, November 18–20, 2018.
