Is the universe a fractal?

For decades, cosmologists have wondered if the large-scale structure of the universe is a fractal: if it looks the same no matter the scale. And the answer is: no, not really. But in some ways, yes. Look, it's complicated.

Quasiperiodicity changes the ground-state properties of 1D narrow-band moiré systems, study demonstrates

Moiré materials, such as twisted bilayer graphene, are materials generally formed by stacking two or more layers of 2D materials on top of each other with a small lattice mismatch. This slight mismatch creates a unique pattern ...

New research analyzes 'Finnegans Wake' for novel spacing between punctuation marks

Statistical analysis of classic literature has shown that the way punctuation breaks up text obeys certain universal mathematical relationships. James Joyce's tome "Finnegans Wake," however, famously breaks the rules of normal ...
