However, some experiments have taken longer than people think. For example, Bell Experiment started from Oxford University in England, and charged two batteries with a metal clock with opposite charges. It has been running until now, thus winning the Guinness World Record for "the most durable battery".
The next experiment, not only boring, but also seemingly meaningless, lasted for a hundred years and two professors died. This is an asphalt dripping experiment. What is it trying to prove?
If you have a chance to go to the laboratory of the School of Physics, University of Queensland, Australia, you may see a funnel covered by a glass cover. The black objects in the funnel are slowly descending into the beaker through the tip of the funnel. Although the liquid seems to be dripping at any time, it is still unbreakable.
As for the occurrence of such a story, I'm afraid it can be traced back to parnell, a physics professor at the University of Queensland, who gave students a question to discuss freely. Is asphalt solid or liquid? In order to prove this conclusion, parnell had a whim. He stuffed some asphalt into a closed funnel and let it settle completely. Three years later, parnell opened the funnel, put it in a beaker, let the asphalt flow slowly, and recorded and observed its daily appearance.
Surprisingly, although asphalt showed signs of decline in the first few years, it took a long time to wait until the first drop of asphalt dripped out. Until one morning when parnell went to the laboratory, he was surprised to find solid asphalt dripping in the beaker. It's a pity that he didn't witness this moment in person. Parnell decided to continue the experiment.
As for the second drop of asphalt, it hasn't dropped yet. At this point, the second world war has been from the outbreak to the end, the third drop of asphalt dripped out, and the fourth drop of asphalt dripped out. ...
Professor parnell used this experiment to prove to students that asphalt is neither a solid nor a liquid, but a complex mixture with extremely high viscosity.
However, Professor parnell didn't get a chance to see more asphalt dripping in the end, and he finally died in the second half. Another physicist, parnell's colleague, John Maynes, took the baton of observation.
