It has been reported that physics researchers located at the University of Adelaide, in Australia, have created a thermometer which is able to pinpoint room temperatures to nearly 30 billionths of a degree. Professor Andre Luiten, who is the chief researcher on the study and also works as a physics professor at Adelaide states that he and his team think the thermometer they have created, is the finest measurement ever made that takes room temperature. Dr. Luiten explained that to make even more detailed measurements might be possible at particularly low temperatures, approaching complete zero with other instruments but it would take more time and research before they would be able to do that.
The scientist explained that to record such microscopic measurements, the thermometer makes use of two different tinted lights. One was the color green and the other was red. They each were injected into an extremely polished crystalline diskette. The temperature of the crystal disturbs the rates at which each of the two lights move, and so the scientists were able to determine the adjacent temperature by watching the transformation in travel time.
He added that by making the light to circulate thousands of times around the edge of the disk in the same way sound concentrates and strengthens itself into a sort of curve in a phenomena which is called a “whispering gallery”, such is seen at St. Paul’s Cathedral in England, then the group of scientists will be able to measure this infinitesimal difference in speed with the greatest of precision.
Professor Luiten stated that when he and his team heated up the crystal they found that the red light starts to slow down by a small quantity with respect to the green light. The research study technology information has been laid out in detail in the most recent edition of the science journal Physical Review Letters.
The scientist and his group at the university’s Institute for Photonics and Advanced Sensing believe that comparable techniques might be able to be achieved to record other radically sensitive measurements such as humidity, air pressure, force or even certain levels of various trace elements.
Dr. Luiten declared that being able to measure numerous different aspects of the environment with such an amazing degree of accuracy, using instruments that are tiny enough to carry around, has the capacity to revolutionize all different sorts of technologies used for a variation of medical and industrial applications where discovery of trace amounts has extreme importance.
