Summary
Fundamental physical constants may have a biofriendly window, influenced by viscosity and diffusion crucial for life. This suggests life
Area of Science:
- Physics
- Biophysics
- Cosmology
Background:
- Understanding fundamental physical constants is key in physics, astronomy, and cosmology.
- The role of these constants in biological systems remains an area of exploration.
Purpose of the Study:
- To explore insights from condensed matter and liquid physics regarding fundamental physical constants.
- To investigate the concept of a 'biofriendly window' for these constants.
Main Methods:
- Analysis of fundamental constants within the context of condensed matter and liquid physics.
- Examination of biofriendly viscosity and diffusion parameters in cellular processes.
Main Results:
- Fundamental constants possess a biofriendly window constrained by viscosity and diffusion essential for life.
- Viscosity, diffusion, and velocity gradients can vary without altering the fine-structure constant or proton-to-electron mass ratio, and without impacting stellar nucleosynthesis.
Conclusions:

258
Newtonian fluids exhibit a constant viscosity, meaning their shear stress and shear strain rate are directly proportional. This property ensures a predictable and stable response to applied forces, maintaining a linear relationship between force and flow. Examples include water, air, and light oils, consistently demonstrating this proportional behavior regardless of external conditions.

5.9K
When water is poured into a glass, it falls freely and quickly, whereas if honey or maple syrup is poured over a pancake, it flows slowly and sticks to the surface of the container. This difference in the flow of different kinds of liquids arises due to the fluid friction between the liquid layers and the liquid and the surrounding material. This property of fluids is called fluid viscosity. In this example, water has a lower viscosity than honey and maple syrup.

01:19Viscosity of Fluid
460
Viscosity measures the resistance a fluid offers to flow and deformation. It results from internal friction between layers of fluid moving relative to one another. Dynamic viscosity, denoted by the Greek letter mu (μ), quantifies the force needed to move one fluid layer over another. For Newtonian fluids like water and air, the relationship between the shearing stress and the rate of shearing strain is linear, meaning their viscosity remains constant regardless of the applied stress.

Surface Tension
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

00:57Physiological Pharmacokinetic Models: Blood Flow-Limited Versus Diffusion-Limited Models
115
Physiological pharmacokinetic models, often called flow-limited or perfusion models, typically assume a swift drug distribution between tissue and venous blood, creating a rapid drug equilibrium. This premise is based on the idea that drug diffusion is extremely fast, and the cell membrane presents no barrier to drug permeation. In this scenario, where no drug binding occurs, the drug concentration in the tissue equals that of the venous blood leaving the tissue. This greatly simplifies the...

01:20Stokes' Law
1.4K
Viscous forces, like friction, are intermolecular forces that resist the relative motion of molecules over each other. When a solid body moves through a liquid, viscous forces drag it in the opposite direction. The force's magnitude depends on the solid's shape and size, as well as its speed and the liquid's coefficient of viscosity, density and temperature.
