The holy grail of coffee physics is predicting Total Dissolved Solids (TDS) as a function of time. This is governed by a simplified version of the for coffee solubles:
Aris became possessed. He built a filter rig from a Zeeman-split electromagnet and sheets of graphene oxide. His lab assistant, a cynical undergrad named Maya, watched him calibrate a laser interferometer to measure the "entanglement angle" of two conically shaped coffee beds.

Higher temperatures increase the kinetic energy of molecules. The holy grail of coffee physics is predicting
Another study published in 2020 in the Journal of Food Science (a leading journal in food science and technology) explored the effects of coffee bean particle size on filter coffee brewing. The researchers used a combination of experiments and simulations to investigate how particle size affects the extraction of solutes during brewing. His lab assistant, a cynical undergrad named Maya,
