Every Non-Newtonian Fluid Explained
What Is a Non-Newtonian Fluid? Time-Independent Non-Newtonian Fluids Time-Dependent Non-Newtonian Fluids The Mathematical Challenge Rheological Models Real-World Applications and Open Problems What Is a Non-Newtonian Fluid? A non-Newtonian fluid is one whose viscosity does not remain constant under different rates of deformation. Unlike Newtonian fluids such as water or air, where the relationship between shear… read more

Every Proof that √2 is Irrational but they get increasingly more complex
Four Proofs That √2 Is Irrational Proof by Contradiction Prime Factorization Proof Infinite Descent Proof Reciprocal Proof Four Proofs That √2 Is Irrational The square root of 2, or 2^(1/2), is irrational. That is, it’s a real number that cannot be expressed as the ratio of two integers. Its decimal expansion is non-terminating and non-repeating.… read more
