Be as competent as Einstein!
Challenge for today
Firstly, let’s deep into the past
Sir Isaac Newton
He described how "normal" liquids or fluids behave. Observed that their viscosity only changes with variations in temperature or pressure.

Guess, what these liquids have in common ?
Newtonian fluids
ketchup
asphalt
'normal' liquids
paint
blood
non-Newtonian fluids
lava
toothpaste

Challenge for today
Definitely not mine...
Non-Newtonian fluids
These are anomalous liquids that do not obey the laws of Newtonian fluids. These liquids change their density and viscosity under the influence of physical forces: mechanical, sound and electromagnetic. They take on the properties of solid bodies.
The connection
between molecules increases
with increasing influence.
The liquid becomes solid!
