The Riddle of the Four Squares
Description
Can every positive integer be expressed as the sum of at most four square numbers? The Four-Square Mystery introduces Lagrange's famous mathematical theorem, exploring how the deep connection between arithmetic and geometry allows us to decompose ordinary numbers into the sums of perfect squares.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
