All questionsHow can abstract mathematics help describe the world?
Move between structures, spaces and applications without assuming that every useful connection is the same kind of explanation.How do we find what we cannot see?
From gravitational waves to distant worlds, follow the steps between a signal and its interpretation.How does life store and use information?
Follow a sequence from DNA to a working cell, then ask how variation changes the picture.Immerse

Why do odd numbers make squares?
1 + 3 + 5 + 7 + 9 = 5²
Each new layer adds the next odd number. The square grows by one row and one column.
