Imagine discovering an ancient treasure chest sealed with a complex dual-lock mechanism, requiring two keys that must work together in a precise way. A matrix—a rectangular array of numbers—is like a locked chest holding valuable information that helps us understand the world around us. Matrices need keys like decompositions, which break them down into simpler components while preserving their essential properties, to help us understand them better. At times, special kinds of decompositions are required to have a deeper understanding of matrices.

Dr. Jose Maria L. Escaner IV, also known as Dr. Joma of the University of the Philippines – Diliman College of Science’s Institute of Mathematics (UPD-CS IM), sadly entered into eternal rest at the beginning of February 2025. His warmth and kindness will be deeply remembered by his students, colleagues, and the rest of the UP Diliman community whom he truly inspired.

Institutions around the globe are working toward creating scientific innovations to address the challenges faced by humanity. Likewise, Filipino scientists are striving to find solutions to the Philippines' concerns.
