tensor

This term carries a heavy technical weight, appearing almost exclusively in physics, engineering, and computer science. It evokes a sense of multi-dimensional geometry where data is not just a list or a grid, but a complex structure that remains consistent regardless of the coordinate system used to measure it. In modern contexts, especially regarding artificial intelligence, the word has shifted from pure theoretical physics into the realm of data processing. It now represents the primary building block of neural networks, where massive arrays of numbers are transformed through linear algebra to recognize patterns in images or text.
