Measuring viscosity dates back to as early as the 19th century. French physicist Jean Poiseuille discovered the concept of measuring viscosity by formulating the "mathematical expression for the flow rate for the laminar flow of fluids in circular tubes." Later on, this formulation was discovered by a German hydraulic engineer Gotthilf Hagen, which came to be known as the Hagen-Poiseuille equation (Britannica). Early measurements of viscosity focused primarily on the flow of blood. Measurements were conducted using the hemodynamometer that incorporated narrow tubes & glass capillaries in effort to measure the pressures in the arteries of horses and dogs (Sutera).
Recently we received our first order from Saudi Arabia. The order is from the leading university in Saudi Arabia and they order an m-VROC® with multiple chips.
We have all read this click bait title many times over.
Yes, we are at the dawn of the autonomous revolution and ultimately, some jobs will be replaced by robots. The good news is that this revolution is going to accelerate science and technology at a rapid pace. The companies and individuals who invest and embrace automation will have a large competitive advantage over those who stick to traditional techniques.
Ok, here’s the scene...An explorer is traipsing through the jungle, visibility is low due to the dense vegetation, he’s chopping away at the vines and plants when suddenly he enters to clearing.

What do we talk about when we talk about viscosity? A series stories of viscosity in life.
Story One - Cosmos and Cosmetics
As marijuana use becomes more mainstream, the use of vaporizer pens or vape pens as a delivery system for THC is steadily increasing in popularity. Vape pens are not your classic bongs as seen in some old school Cheech and Chong movies, but are in fact a high-tech device; a high-tech device where precision and accuracy are critical to performance.
First of all, the question is-- can there be a coffee or liquid with zero viscosity coffee? We know that there is negative viscosity. Is having zero viscosity similar?
Viscosity is the resistance of a fluid to flow and it comes from the friction of molecules as they move against each other within the fluid. All fluids have at least some resistance to flow – except super fluids.
Researchers from UC San Diego have come up with a radically different solution for severe blood loss treatment. In their study, fluids with much higher salt content than conventional saline are combined with viscosity enhancers with the purpose of thickening blood.
Creation of foods and beverages has been researched and been developed into its own science. Did you know that the viscosity of the foods that you eat also affects the taste? Just as texture, the thickness of a sauce, the ooey-gooey melted cheese, and even your saliva as you read this sentence all has a viscosity.
I tried my own combination for Mac & Cheese, what do you think?
Oobleck, a common name for the final product of mixing corn starch with water. Not only is it named after the mysterious materials falling from the sky in the Dr Seus's story, "Bartholomew & the Oobleck," this combination of materials is a great example of non-Newtonian fluid. (What is a non-Newtonian Fluid? What is Newtonian?)
