One of the world's most sensitive thermometer: precision up to 30 billion points at one time

According to the daily mail, at present, the scientists of the latest development of the world's most sensitive thermometer, it can measure 3/100000000 change the subtle difference. The device is called & other; Nano kelvin thermometer & throughout; Three times than before, the most accurate precision thermometer. It is very accurate, scientists say, this kind of thermometer can measure atomic structure when the target object motion when the temperature changes. Andre - at the university of Adelaide, Australia Lu teng ( AndreLuiten) Professor is project director, he said: & other; We think that this is so far the best room temperature environment temperature measuring device, in order to highlight the accuracy of the thermometer, we tested the temperature of the object, found that it's always in a state of temperature fluctuations. ” If you close observation, will find any material all the atoms in the total under vibration, we see the real numerical fluctuation on the thermometer, also confirmed the micro world always in a state of motion. The new study published in the journal physical review letters, & other; Nano kelvin thermometer & throughout; Are red and green light thousands of loops on the edge of the disk crystal. Based on the crystal temperature difference, both the speed of light is slightly different.
