Bonfire

“The prettiest sight I know,

Worth all your roses and snow,

Is the blaze of light on a Saturday night”

The Princeton Bonfire (a cherished campus tradition celebrating a sweep of football victories over Big Three rivals Harvard and Yale) has not yet occurred in 2025, as it depends on the outcomes of those games. The relevant schedule is:

vs. Harvard: October 25, 2025 (home game at Princeton Stadium)
vs. Yale: November 15, 2025 (home game at Princeton Stadium)

If Princeton wins both (securing the “Big Three” title), the bonfire is traditionally lit on the Sunday evening immediately following the Yale game—that is, November 16, 2025, around 7 p.m. on Cannon Green. It would feature student-built stacks of wood, speeches, the Princeton University Band, and communal festivities.

History of Western Civilization Told Through the Acoustics of its Worship Spaces

Abstract. Insights into the history and future of western civilization are found by applying information theory to the acoustical communication channel (ACC) of its worship spaces. Properties of the ACC have both influenced and reflected the choice of message coding (e.g., speech or music) at various times. Speech coding is efficient for acoustically dry ACCs, but hopeless for highly time-dispersive ACCs. Music coding is appropriate for time dispersive (reverberant) ACCs. The ACCs of synagogues, early Christian house churches, and many Protestant churches are relatively acoustically “dry” and thus well suited to spoken liturgies.

The spoken liturgy, dominant in synagogues, was carried over to early Christian churches, but became unworkable in Constantinian cathedrals and was largely replaced with a musical liturgy. After a millennium, the cathedral acoustic was altered to suit the doctrinal needs of reformation churches with its renewed emphasis on the spoken word. Worship forms continue to change, and the changes are reflected in the properties of the ACC. The pulpits of electronic churches may be evolving into radio and television performance spaces and naves into worshipers’ living rooms.

Tyme

“Tyme” was used in Middle English and earlier forms of the language, and it was commonly found in historical texts, poetry, and manuscripts of that time. It was used to refer to the passage of time, an era, or a specific moment in history.

Today at 16:00 UTC we refresh our understanding of the technical standards for the timing-systems that maintain the temporal framework for daily life in education communities. The campus clock continues as a monument of beauty and structure even though digitization of everything has rendered the central community clock redundant.

Most leading practice discovery (and innovation) is happening with the Network Time Protocols (NTP) that synchronize the time stamps of widely separated data centers. In operation since before 1985, NTP is one of the oldest Internet protocols in current use and underlies the Internet of Things build out. NTP is particularly important in maintaining accurate time stamps for safety system coordination and for time stamps on email log messages.

Outdoor Deicing & Snow Melting

Electrical Safety

“Snow at Argenteuil” | Claude Monet (1875)

Today our focus turns to outdoor electric deicing and snow melting wiring systems identified as suitable for the environment and installed in accordance with the manufacturer’s instructions. They work silently to keep snow load from caving in roofs and icicles falling from gutters onto pedestrian pathways.

While the voltage and ampere requirement of the product itself is a known characteristic, the characteristic 0f the wiring pathway — voltage, ampere, grounding, short circuit, disconnect and control — is relatively more complicated and worthy of our attention. Articles 426-427 of the National Electrical Code is the relevant part of the NEC

Free Access 2023 National Electrical Code

Insight into the ideas running through technical committee deliberations is provided by a review of Panel 17 transcripts:

2023 NEC Panel 17 Public Input Report (633 pages)

2023 NEC Panel 17 Public Comment Report (190 pages)

We hold Articles 427 in the middle of our priority ranking for the 2023 NEC. We find that the more difficult issues for this technology is the determination of which trade specifies these systems — architectural, electrical, or mechanical; covered in previous posts. Instead, most of our time will be spent getting IEEE consensus products in step with it, specifically ANSI/IEEE 515 and IEEE 844/CSA 293.

Comments on the Second Draft of the 2026 NEC will be received until April 18th.

We collaborate with the IEEE Education & Healthcare Facility Committee which meets online 4 times per month in European and American time zones. Since a great deal of the technical basis for the NEC originates with the IEEE we will also collaborate with IEEE Standards Coordinating Committee 18 whose members are charged by the IEEE Standards Association to coordinate NFPA and IEEE consensus products.
