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

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 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. 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 See also
Symbaloo World Population Clock: 7.4 Billion People (2016) World Population: Past, Present, and Future (move and expand the bar at the bottom of the chart to navigate through time) The chart above illustrates how world population has changed throughout history. View the full tabulated data. At the dawn of agriculture, about 8000 B.C., the population of the world was approximately 5 million. A tremendous change occurred with the industrial revolution: whereas it had taken all of human history until around 1800 for world population to reach one billion, the second billion was achieved in only 130 years (1930), the third billion in 30 years (1960), the fourth billion in 15 years (1974), and the fifth billion in only 13 years (1987). During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion. Wonder how big was the world's population when you were born? Growth Rate Yearly Growth Rate (%) Annual growth rate reached its peak in the late 1960s, when it was at around 2%. World Population (2019 and historical) Jews
The Many Faces of Global Migration Description: The Many Faces of Global Migration report is an introduction to what Gallup has unearthed by asking migrants and potential migrants worldwide about their lives. The data presented in this report are based on Gallup’s ongoing World Poll surveys in more than 150 countries, territories and regions and more than 750,000 interviews since 2005. As such, these findings provide an unprecedented look at the different push-and-pull factors that influence migration, the experiences of those who desire to migrate to other countries permanently or temporarily for work, those who are planning to go, those who are preparing to go, those who have already left, and those who have returned home – and what this means for governments, intergovernmental and non-governmental organizations, and other stakeholders.
