Recent Activity
Atomistics is a branch of science that has grown out of the application of quantum mechanics to molecular and condensed matter systems. For much of the past five or so decades, these two sciences have progressed along parallel tracks, yet recently these tracks have started to intersect and intertwine. Traditionally...

Today our men's ministry group from New Beginnings organized and sponsored a Father's Day weekend rocket launch at Overlook Park. As to be expected, the event was a blast, and got me thinking, what's so difficult about rocket science? After all, even today kids were putting snap together kits, dads... Continue reading

After a dry spell in the wilderness of parenting and an early career I turned again to one of the guilty pleasures of my life - science fiction. Recommended by our local kids' librarian I signed up on NetGalley and trolled through the Angry Robot catalog, settling on a fun-looking... Continue reading

Coarse-graining can be an effective way to increase the length and time-scale of a molecular dynamics (MD) simulation. Most of my MD work has been performed using ab initio methods, like density functional theory (DFT), and I am lucky if I can breached picoseconds in most of my simulations. Coarse-grained...

But should phd's not receive, and expect to receive, some kind of renumeration as the end goal, a healthy job that is in some way reflective of the hard work that has been achieved? Certainly there are many niche positions that reward phds in this way. Continue reading

Today's seminar speaker was J. S. Langer (emeritus, UCSB) and he spoke about a thermodynamic model for strain hardening in materials, where increasing strain-rates can lead to stronger effective moduli in the material. Continue reading

The search for universal laws and relations is one of the grand themes of science. Scientists love searching through reams of data, looking for patterns and hidden relationships, postulating theories as to why such and such correspondences may exist, and taking a perverse delight in discovering exceptions to those rules. Continue reading

...if the ambitious claim made on the website to make it possible for "atomistic simulations that will enable any interatomic model to work with any simulation code" is met, huge doorways will be opened up into the world of materials science modeling and simulation, and the technologies of tomorrow will be the primary beneficiaries. Continue reading

For small molecules, we can, conceivably, incorporate enough physical effects to describe the electronic ground-state to desirable numerical precision. But, for most of reality, we cannot: approximations must be made. Continue reading

The rules in chemistry were based on intuition, the elements had complex 'personalities', 'families' and periodic 'trends', and for every rule there were a handful or more of mystifying exceptions (for example, see the 18-electron rule in inorganic chemistry -- organic chemistry, on the other hand, seemed relatively well-tamed and, therefore, bland). Quantum mechanics (QM) provided the framework that seemed to explain all of these relations, and their exceptions, not only of the elements themselves, but their laws of combination, reaction, thermodynamics and self-assembly (I later discovered that statistical mechanics (SM) provided another important piece).
