About the Pitch Drop Experiment While the School of Mathematics and Physics at The University of Queensland has an international reputation for cutting-edge research and innovative teaching in the disciplines of Mathematics, Physics and Statistics, it is also home to the famous Pitch Drop Experiment. The experiment is listed in the Guinness Book of World Records as the world's longest-running laboratory experiment. The first Professor of Physics at UQ, Professor Thomas Parnell, began an experiment in 1927 to illustrate that everyday materials can exhibit quite surprising properties. The experiment demonstrates the fluidity and high viscosity of pitch, a derivative of tar once used for waterproofing boats. Live view of the Pitch Drop Experiment More information
OCR it :) It is WORKING Pitch drop experiment The University of Queensland pitch drop experiment, featuring its then current custodian, Professor John Mainstone (taken in 1990, two years after the seventh drop and 10 years before the eighth drop fell). University of Queensland experiment[edit] The eighth drop fell on 28 November 2000, allowing experimenters to calculate that the pitch has a viscosity approximately 230 billion (2.3×1011) times that of water.[2] This is recorded in Guinness World Records as the world's longest continuously running laboratory experiment, and it is expected that there is enough pitch in the funnel to allow it to continue for at least another hundred years. This experiment is predated by two other still-active scientific devices, the Oxford Electric Bell (1840) and the Beverly Clock (1864), but each of these have experienced brief interruptions since 1937. Professor Mainstone subsequently commented: Professor John Mainstone died on 23 August 2013 following a stroke. Timeline[edit] See also[edit]

Introduction: This interactive infographic from Number Sleuth accurately illustrates the scale of over 100 items within the observable universe ranging from galaxies to insects, nebulae and stars to molecules and atoms. While other sites have tried to magnify the universe, no one else has done so with real photographs and 3D renderings. How To Use: Credits:
Mozilla Thimble ღ Liquid breathing Perfluorochemical (perfluorocarbon) molecules have very different structures that impart different physical properties such as respiratory gas solubility, density, viscosity, vapor pressure, and lipid solubility.[1] Thus, it is critical to select the appropriate PFC for a specific biomedical application, such as liquid ventilation, drug delivery or blood substitutes. The physical properties of PFC liquids vary substantially; however, the one common property is their high solubility for respiratory gases. In fact, these liquids carry more oxygen and carbon dioxide than blood.[2] In theory, liquid breathing could assist in the treatment of patients with severe pulmonary or cardiac trauma, especially in pediatric cases. Approaches[edit] Computer models of three perfluorochemical molecules used for biomedical applications and for liquid ventilation studies: a) FC-75, b) perflubron, and c) perfluorodecalin. Total liquid ventilation[edit] Partial liquid ventilation[edit] PFC vapor[edit]
Home Page 11 Free Tools to Teach Human Anatomy in 3D The following are some good resources to help students explore the human body through interactive imaging, games, exercises and more. Build-a Body: This is a great website that allows students to build the human body using interactive elements system by system. Each system has descriptions and provides some facts about diseases. Students will only drag and drop the parts of body such as bones, organs,..ect. BioDigital Human This is a great resource for anatomy. Medical Animations The university of Pennsylvania Health System has a great website offering medical animations, explanations of several medical problems, resources on anatomy, physiology, and the human body. InnerBody This is a website where students can learn about human anatomy and physiology. Zygote Body This is the the substitute of Google Body. Virtual Eye Dissection and Eye Anatomy As its name suggests, this website lets users view photos from an actual eye dissection, and perform virtual dissection on the eye.
