On this day in physics: 28 March 1946- Happy Birthday to Wubbo Ockels, a Dutch astronaut who would have turned 70 today. He was the first Dutch citizen in space and did so aboard the American Space Shuttle.

Word of the Day- A Matrix is a square or rectangular array of numbers. A matrix is defined by how many rows and columns it has. For example, a matrix with 2 rows and 3 columns is referred to as a "2 by 3" matrix. The plural of matrix is matrices. Matrices are very useful for describing quantities which may exist in multiple dimensions, such as vector quantities or tensor quantities. They make very complicated numerical situations very easy to manipulate and are used in almost every facet of physics and mathematics. If you have ever computed a cross product, you have essentially dealt with matrices before, even if you didn't know it.

Keywords: Matrix, Space Shuttle.
