Physics of Data Flow

Welcome new subscribers!

Last week the Construction Specifications Institute (CSI) Northern Virginia Chapter (CSI NOVA) welcomed scientists from the NIST Fire Research Lab to give a talk about fire simulations and the new test facility.

NIST’s Fire Dynamics Simulator (FDS)

A couple simulations were of just the fires themselves rather than walls, furniture, elevator shafts and other elements that might influence where a fire would move next in a building. The NIST Fire Research lab studies both the effects and relationships of different building materials with fire, and the physics of fire by itself. The physics of fire by itself has some known properties, such as maximum temperatures, and the short SHORT flashover point. The space around a fire is not always needed for better understanding of what a fire is likely to do next.

Today we have a lot of data moving around the Internet. Behaviors and patterns in the physics of data flow may have properties like maximum temperatures or flashover points in fires.

However it seems like most of these studies only look at the data, rarely the space around. As if the way different areas of the Internet were built, or the composition of various user communities, could influence where data are likely to go next and whether they are likely to spread quickly or slowly smolder. Below is an image about the flow of physics data from CERN, but who is studying the physics of data flow? Or more importantly, structural details about spaces around data, or how more precise configurations might help push relevant information into specific areas that are most conducive to those particular ideas catching on, spreading, and growing… Until at some point, inevitably, even the most gigantic ideas, like fires, will eventually die out. We are still learning about the physics of fire today, the physics of data flow and a better understanding of the life cycle of ideas and information may take many MANY generations of study until the statistics and calculations are relatively accurate, or at least aligned with the unpredictable real world.



In architectural construction documents, elements may appear many times in the drawings but are only specified in one location in the project manual. To assure consistency and to know where to look for information, the American Institute of Architects (AIA) and Engineers Joint Contract Document Committee (EJCDC) established a Uniform Location of Subject Matter published in AIA Document A521/EJCDC 1910-16. Uniform subject matter locations for contracting and building the semantic world needs to be defined also.

What would be the most functional layout to show a full spectrum of information use in semantic space?

But how to accommodate and show various digital materials being transmitted, for example images, text, video, sound recordings etc. It may be better to establish a lay out similar to the electromagnetic spectrum as shown by the Division of Chemistry Education at Purdue University.

What about the pace information is exchanged? Perhaps quantum mechanics diagrams like this one by Alyssa A. Goodman at the Harvard-Smithsonian Center for Astrophysics would work.
