In addition to the above limitations of science historical science is limited by the fragmentary nature of the artifacts it is able to find in effect the accuracy of ideas is limited by the assumptions chosen by the researchers kar dating is based on assumptions kar dating is not based on irrefutable data alone.
This essay is about the limitations of science as science does not provide answer to most of the questions this seems to be that science is limited this essay is also about when science is beyond the limits then it provides danger and threat to the world.
The principle limitation of the 40 ar 39 ar dating method is the presence of calcium in the sample which produces interfering argon isotopes during neutron irradiation the extent of interference on the potassiumargon age is primarily a function of the age and the calcium concentration.
The 40 ar 39 ar dating method can overcome these limitations of conventional kar dating and has the added advantage that potassium and argon are determined on the same sample and that only measurements of the isotopic ratios of argon are required the method is suitable for use with small and precious samples such as extraterrestrial materials.
Potassiumargon dating is accurate from 43 billion years the age of the earth to about 100000 years before the present at 100000 years only 00053 of the potassium40 in a rock would have decayed to argon40 pushing the limits of present detection devices.

science is powerful it has generated the knowledge that allows us to call a friend halfway around the world with a cell phone vaccinate a baby against polio build a skyscraper and drive a car.
The physical procedure for 40 ar39 ar dating is the same except for three differences before the mineral sample is put in the vacuum oven it is irradiated along with samples of standard materials by a.
