Math and Sciences, University of New Mexico, Gallup, NM, USA Florentin Smarandache In Neutrosophic Logic, a basic assertion is that there are variations of about everything that we can measure; the variations surround three parameters called T,I,F (truth, indeterminacy, falsehood) which can take a range of values. Similarly, in this paper we consider NL applications in physics constants. Those constants actually all have a window of plus and minus values, relative to the average value of the constant. For example, speed of light, c, can vary in a window up to +- 3000 ms. Therefore it should be written: 300000 kms +- 3 kms. We also discuss some implications of this new perspective of physics constants, including in gravitation physics etc.  2020 2020 14 18 10.54216/IJNS.010105
