1859 CE and beyond: Some reflections
The yuga between 1800 CE and 1900 CE saw a remarkable change in our understanding of the world at many levels. It is not that some of these ideas did not exist long before that time but they came together … Continue reading

Pattern formation in coupled map lattices with the circle map, tanh map, and Chebyshev map
The coupled map lattices (CMLs), first defined by Kunihiko Kaneko around the same time Wolfram was beginning to explore cellular automata, combine features of cellular automata with chaotic maps. The simplest CMLs are defined on a one dimensional lattice with … Continue reading

The upper story in a few pictures
We have always held that there is no substitute to the knowledge gained from handling real data. It is always superior to one gained from mere reading without reproducing or selfinvestigation. Hence, we have endeavored to play with various objects … Continue reading

Some elementary lessons from iterative fractal maps
The famous Sierpinski gasket was one of the first fractals we wrote code for when we got access to a computer. It impressed us enormously that an intricate object with selfsimilarity over all scales could be generated by a rather … Continue reading

Tyrannosaurs of the south redux: megaraptorans as tyrannosaurs?
Shortly after we had reached the mlechChaland we read an abstract of a presentation in a meeting on vertebrate paleontology where Argentinian scientists reported the discovery of a large theropod (~6m long) with huge claws. At that point those claws … Continue reading
A brief note on haramiyidans and the Mesozoic radiation of the mammals
Mammals have a longer history in the “age of the dinosaurs” (Mesozoic) than in the “age of the mammals” (Cenozoic). However, much of the Mesozoic history of the mammals remains obscure, not in small part due to the fact that … Continue reading
