Abstract: Empirical formulas are proposed for the superdirectivities of broadside linear and square arrays. The formulas are derived based on a large amount of numerical results of optimum directivity ...

Malanga root is rich in B vitamins, potassium, and complex carbohydrates. Malanga should not be eaten raw because it contains oxalic acid. People with high potassium levels should avoid malanga root.

This video explores one of Leonhard Euler’s most elegant ideas, showing how factorials can be used to connect π, square roots, and one-half in a surprising and beautiful way. Through clear ...
