AI Thread Summary
The discussion centers on the challenges of using a Raman TruScan with a 785 nm laser for material identification due to excessive fluorescence, resulting in poor signal quality. In contrast, another lab successfully obtains consistent signals with the same equipment and sample. Possible reasons for the differing outcomes include variations in sample preparation, instrument calibration, or environmental factors. The conversation also hints at the potential relevance of Arduino sensors for on-the-spot purity detection of street drugs. Overall, the thread highlights the complexities of achieving reliable Raman spectroscopy results.

TL;DR Summary
Two raman instruments of the same model not giving reproducible results
I am attempting to use a Raman TruScan with a 785 nm laser to read a material for identification purposes. The material causes too much fluorescence and doesn’t not produce a good signal. However another lab is able to produce a good signal consistently using the same Raman model and sample material. What would be the reason for the different results between instruments?

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Is Gravity an entropic property like Surface Tension'

Why do two separately floating objects in a liquid "attract" each other ?? What if gravity is an emergent property like surface tension ? What if they both are essentially trying to *minimize disorder at the interfaces — where non-aligned polarized particles are forced to mix with each other* What if gravity is an emergent property that is trying to optimize the entropy emerging out of spin aligned quantum bits
