My Oct. 13 National Fossil Day public lecture, “Lost Giants of the Jurassic”, for the Museums of Western Colorado – Dinosaur Journey is now up on their YouTube channel. First 48 minutes are talk, last 36 minutes are Q&A with audience, moderated by Dr. Julia McHugh. New stuff from the 2021 field season — about which I’ll have more to say in the future — starts at about the 37-minute mark.

Last time, we looked at the difference between cost, value and price, and applied those concepts to simple markets like the one for chairs, and the complex market that is scholarly publication. We finished with the observation that the price our community pays for the publication of a paper (about $3,333 on average) is about 3–7 times as much as its costs to publish ($500-$1000)? How is this possible?

We have a tendency to be sloppy about language in everyday usage, so that words like “cost”, “value” and “price” are used more or less interchangeably. But economists will tell you that the words have distinct meanings, and picking them apart is crucial to understand economic transaction. Suppose I am a carpenter and I make chairs: The cost of the chair is what it costs me to make it: raw materials, overheads, my own time, etc.

How does Underworld scale on a HPC? In this post we showcase how Underworld 2.11 scales across two of Australia's premiere HPC systems. Gadi - https://nci.org.au/our-systems/hpc-systems Magnus - https://pawsey.org.au/systems/magnus/ The reference model chosen for this scaling showcase is a extended 3D stokes flow: Analytic Solution SolDB3D . Q1P0 elements were used and a fixed solver iteration count for solving the saddle point problem.

“Existing metadata are an exciting learning set for discerning patterns that can be used to streamline the metadata creation process. We want to ensure that data are being submitted to the best fit repository with the right metadata.

Last week's Woods Point earthquake in Victoria was a quite a surprise for most Australians outside the geophysical community and even among Earth scientists, an event of this magnitude was unexpected.

On the morning of September 22, a magnitude-5.9 earthquake struck approximately 130 km northeast of Melbourne. Seismic waves were felt in Melbourne, Canberra, Sydney and Adelaide, and as far south as Tasmania.
