Translucent Spot: Why and Is it Related to Adsorption?

Thread starter Harmony
Start date Aug 28, 2006

AI Thread Summary

Translucent spots appear when lipid-containing food is rubbed against paper due to the scattering of light by fat molecules. This phenomenon is linked to adsorption, where fat molecules interact with the paper's surface. The light is absorbed and re-emitted internally, allowing some light to pass through. The exact mechanism of this interaction remains unclear. Understanding this process could provide insights into the behavior of lipids on various surfaces.

It means that the light rays are scattered by the fat molecules and can be absorbed and re-emitted internally thereby transmitting some light to the other side. But I do not know how the mechanism actually works.

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks

Thread 'Fundamental Probability'

If the universe is fundamentally probabilistic, and all possible outcomes are realized in some branch of the multiverse, does that invalidate the concept of scientific inquiry? If knowledge is merely a description of one particular branch of reality, does it have any inherent value?
