this post explores the importance of getting little details right, consideration of the audience in the inclusion of such details, and the role of science in, well, science fiction.
Self-Assembly and Repair for In-Situ Resource Utilization
This review will address the state of the art in self-assembly and self-repair technologies and understanding, with an emphasis on applicability to a durable space presence and space resource extraction and utilization.
Galileo’s Notes on Ptolemy
Copernicus and Galileo, who are credited (perhaps in slightly overstated fashion) with entirely recontextualizing our place in the universe, are thought of in this way, but the reality is that most seemingly revolutionary thinkers were less people who ran in a different direction from everyone else, and more people who saw the trail ahead more clearly and could take the next few steps for us.
Continuously Quantum Reality
In a recent essay from Quanta Magazine, “Are the Mysteries of Quantum Mechanics Beginning to Dissolve,” Ball argues for a resolution to these seeming contradictions proposed by Zurek in a recent book called Decoherence and Quantum Darwinism.
Comment Opportunity – NASA Technology Shortfalls
NASA is working on updating the shortfalls list, and they’ve changed the format in a way that maintains the detail while eliminating some of the overlaps and providing a higher-level basis for the ranking of shortfalls against each other.
Linguistics, LLMs, and Empiricism’s Dangers
This word “understanding” is being used to examine a broader, more philosophical question of motivation, of trying to parse why the LLMs respond to queries in the ways they do, but today’s, and the foreseeable future’s worth of tomorrow’s, LLMs don’t have motivation in the human sense.
Regolith as a Material Resource Priority
Structural materials like regolith should be prioritized, followed by water from which both propellant and life support can be derived.
An Interstellar Interloper
Any spacecraft wishing to rendezvous with 3I/ATLAS will need to match its velocity, and hyperbolic interstellar trajectories are fast. I did some quick, back-of-the-envelope calculations to find just how fast.
Computational Engineering – Engineering from First Principles
At its core, computational engineering is engineering from first principles. Rather than the engineer's job being to develop geometry, in computational engineering the engineer's job is to determine the specifications and parameters which will drive geometry and provide them to the computer.
Funding for Fundamentals
If the conversation is not had, if there are only sides, statements, and declarations, more will be lost than a few years of erratic funding.
