Sunday pot-pourri #1

Every Sunday I publish a pot-pourri of interesting things I came accross in the past week plus some suggested material.

  • Reading #1: Ever wondered why Roman concrete structures are still standing even when battered by sea waves for 2,000 years while modern constructions erode over few decades? It has been discovered recently that the secret lies in the incorporation of volcanic ash. But the original recipe remains unkown. Roman Concrete.
  • Reading #2: What is Data science? The Harvard Data Science Review aims at defining and shaping what it is or what it should be … by listing what it is not. Data Science: An Artificial Ecosystem.
  • Reading #3: The pre-Islamic history of Arabia is mysterious, fascinating, and … almost completely unknown. But things are changing fast. A New History of Arabia, Written in Stone.
  • Figure: The World fertility rate is expected to converge to about 2 (i.e., around a zero population growth rate) by 2100.
  • Video: An ode to design, architecture, and photograhy
