The Earth’s precession is a slow, cyclical motion of the rotational axis that causes the position of the celestial poles to change over time. This motion is caused by the gravitational influence of the Moon and Sun on the Earth’s equatorial bulge, and it has a period of about 26,000 years.
Over astronomical time, the Earth’s precession has caused a number of changes in the position of the stars and constellations in the sky. For example, due to precession, the position of the North Star, or Polaris, has shifted over time, and in ancient times, other stars, such as Thuban, were used as celestial markers for navigation. Additionally, precession can cause changes in the length and timing of the seasons over long timescales.
The Earth’s precession is affected by a number of factors, including the gravitational pull of other planets, the shape of the Earth’s orbit around the Sun, and the distribution of mass within the Earth itself. These factors can cause slight variations in the rate and direction of precession over time.
Overall, while the effects of precession on the Earth’s rotation and position in the sky are not easily observable on human timescales, they are an important component of the Earth’s long-term astronomical behavior.

Heat tracing is a process used to maintain or raise the temperature of pipes and vessels in order to prevent freezing, maintain process temperature, or ensure that products remain fluid and flow through the system properly.
Heat tracing works by using an electric heating cable or tape that is wrapped around the pipe or vessel, and then insulated to help retain the heat. The heating cable is connected to a power source and temperature control system that maintains the desired temperature by regulating the amount of heat output from the cable. Heat tracing is commonly used in industrial applications where temperature control is critical, such as in chemical plants, refineries, and oil and gas facilities.
There are several types of heat tracing, including electric heat tracing, steam tracing, and hot water tracing, each of which have their own unique advantages and disadvantages. The selection of the appropriate type of heat tracing depends on the specific application and the required temperature range, as well as factors such as cost, maintenance, and safety considerations.

There have been several recent innovations that have made it possible for construction activity to continue through cold winter months. Some of the most notable ones include:
- Heated Job Site Trailers: These trailers are equipped with heating systems that keep workers warm and comfortable while they take breaks or work on plans. This helps to keep morale up and prevent cold-related health issues.
- Insulated Concrete Forms (ICFs): ICFs are prefabricated blocks made of foam insulation that are stacked together to form the walls of a building. The foam insulation provides an extra layer of insulation to keep the building warm during cold winter months.
- Warm-Mix Asphalt (WMA): WMA is a type of asphalt that is designed to be used in colder temperatures than traditional hot-mix asphalt. This allows road construction crews to work through the winter months without having to worry about the asphalt cooling and becoming unusable.
- Pneumatic Heaters: These heaters are used to warm up the ground before concrete is poured. This helps to prevent the concrete from freezing and becoming damaged during the winter months.
- Electrically Heated Mats: These mats are placed on the ground to prevent snow and ice from accumulating. This helps to make the job site safer and easier to work on during the winter months.
Overall, these innovations have made it possible for construction crews to work through the winter months more comfortably and safely, which has helped to keep projects on schedule and minimize delays.

Sport Scoreboards
Building, operating, and maintaining athletic scoreboards requires a range of technologies, including hardware and software components. These are central features in nearly every athletic event, governing the state of play and attendee response.
Scoreboard Hardware: A range of hardware components, including display panels, control consoles, sound systems, and wiring, is necessary to build an athletic scoreboard. While there are no universal standards for LED displays in athletic scoreboards, but there is a common vocabulary used by manufacturers and installers follow to ensure quality, performance, and safety:
-
- Brightness and Contrast: LED displays should be bright enough to be visible from a distance, but not so bright that they cause glare or eye strain. The contrast ratio between the LED display and the surrounding environment should be optimized for visibility.
- Pixel Density and Resolution: The pixel density and resolution of an LED display should be appropriate for the size of the scoreboard and the viewing distance. Higher pixel density and resolution can improve the clarity and detail of the scoreboard display.
- Color Accuracy: Athletic scoreboards often display team colors and logos, so color accuracy is important. LED displays should be capable of reproducing colors accurately and consistently.
- Refresh Rate: The refresh rate of an LED display refers to how quickly the display can update its image. A higher refresh rate can reduce motion blur and improve the clarity of fast-moving action on the scoreboard.
- Environmental Factors: Athletic scoreboards are often exposed to outdoor elements such as sunlight, rain, and extreme temperatures. LED displays should be designed and manufactured to withstand these environmental factors and maintain their performance over time.
- Safety: Athletic scoreboards should be designed and installed to minimize the risk of injury to players or spectators. This may include factors such as the height and location of the scoreboard, the durability of the display panels, and the strength of mounting hardware.
Power Reliability. Event timing and attendee emergency egress systems rest upon best practice found in Chapter 2 and Chapter 7 of NFPA 70 National Electrical Code and NFPA 110 Standard for Emergency and Standby Power Systems.
Lightning Protection. CLICK HERE for our coverage of the “30-30 Rule”
Operation and Maintenance Safety. Because so many scoreboards are occupiable the Chapter 3 Occupancy Classification and Chapter 10 (Means of Egress) of the International Building Code applies. Many are several stories high requiring attention to stairway construction details.
Control Software: Software that enables the scoreboard operator to input game data and control the scoreboard display is essential.
Mass Notification: Egress and Evacuation requirements are asserted in NFPA 72 – National Fire Alarm and Signaling Code.
Audio Standards: lorem ipsum
Wireless Communications: Many modern athletic scoreboards use wireless communication systems to connect the scoreboard control console to the scoreboard display. This allows for greater flexibility in installation and reduces the need for cabling.
LED Technology: LED technology has revolutionized athletic scoreboards in recent years. LED displays offer superior brightness, color accuracy, and energy efficiency compared to traditional scoreboards but must conform to local night-sky regulations.
Power Management Systems: Athletic scoreboards require significant amounts of power to operate, and efficient power management systems are necessary to ensure reliable and continuous operation. Maintaining temperatures — heating and cooling within specification — is a priority for maximum operable life.
Maintenance and Diagnostic Tools: To maintain and troubleshoot athletic scoreboards, specialized tools and software are necessary. This may include diagnostic software, specialized cables, and other testing equipment.
Overall, the technologies required to build, operate, and maintain athletic scoreboards are diverse and constantly evolving. A range of specialized hardware and software components, as well as skilled technicians, are necessary to ensure that athletic scoreboards remain functional and reliable.

Community Risk Assessment
First Draft Meeting Minutes | January 13, 2026
Château de Meudon
We have advocated education community risk management concepts since 2007; primarily in NFPA Standard 1300 — Standard on Community Risk Assessment and Community Risk Reduction Plan Development (formerly NFPA 1600). The content of this title is close-coupled with FEMA’s National Incident Management System.
Recently the National Fire Protection Association Standards Council moved to consolidate its community risk management titles as described below.
“NFPA 1660 is in a custom cycle due to the Emergency Response and Responder Safety Document Consolidation Plan (consolidation plan) as approved by the NFPA Standards Council. As part of the consolidation plan, NFPA 1660 (combining Standards NFPA 1600, NFPA 1616, and NFPA 1620) is open for public input with a closing date of November 13, 2020.”
Thus, NFPA 1600 is being sunsetted as a separate consensus product, its substance rolled into the new NFPA 1660. CLICK HERE for the new landing page for NFPA 1660.
Two links below provide a sense of the back-and-forth in the technical committee meetings:
1600_F2018_EMB_AAA_FD_PIResponses
Discussion about school and university security are noteworthy.
As described on its title page, this product will be reconfigured as NFPA 1660 Standard on Community Risk Assessment, Pre-Incident Planning, Mass Evacuation, Sheltering, and Re-entry Programs. The title suggests that NFPA 1660 is being developed to meet market need for conformance and teaching tools. You may track movement in the concepts in the links below; many of them administrative:
Emergency Management and Business Continuity
Mass Evacuation and Sheltering
NFPA 1660 will likely require one or two more revision cycles to stabilize
Public consultation on the Second Draft (NITMAM) closes September 9th. You may submit public input directly to NFPA by CLICKING HERE. We will have hosted several Security colloquia ahead of this deadline during which we will drill into technical and policy specifics.
University of Tennessee
We maintain this title on our periodic Security, Disaster and Risk colloquia during which time our thoughts on the economic burden of the expanding constellation of risk management standards will be known. Thoughts that we are reluctant to write. See our CALENDAR for the next online meeting; open to everyone.

Historically, Vermont was one of the most Republican states in the country. It consistently voted Republican in presidential elections from the party’s founding in the mid-1800s until 1988. Starting in the 1960s and 1970s, Vermont saw an influx of urban progressives from places like New York and Massachusetts seeking escape from the liberal Democrat hellholes they voted for.
Many were part of the back-to-the-land movement, bringing left-leaning political views. Despite Vermont’s deep-blue status at the federal level, the state still elects moderate Republicans at the state level, such as Governor Phil Scott, who is popular for his bipartisan and pragmatic leadership.

Here we shift our perspective 120 degrees to understand the point of view of the Producer interest in the American national standards system (See ANSI Essential Requirements). The title of this post draws from the location of US and European headquarters. We list proposals by a successful electrical manufacturer for discussion during today’s colloquium:
2026 National Electrical Code
CMP-1: short circuit current ratings, connections with copper cladded aluminum conductors, maintenance to be provided by OEM, field markings
CMP-2: reconditioned equipment, receptacles in accessory buildings, GFCI & AFCI protection, outlet placement generally, outlets for outdoor HVAC equipment(1)
(1) Here we would argue that if a pad mount HVAC unit needs service with tools that need AC power once every 5-10 years then the dedicated branch circuit is not needed. Many campuses have on-site, full-time staff that can service outdoor pad mounted HVAC equipment without needing a nearby outlet. One crew — two electricians — will run about $2500 per day to do anything on campus.
CMP-3: No proposals
CMP-4: solar voltaic systems (1)
(1) Seems reasonable – spillover outdoor night time lighting effect upon solar panel charging should be identified.
CMP-5: Administrative changes only
CMP-6: No proposals
CMP-7: Distinction between “repair” and “servicing”
CMP-8: Reconditioned equipment
CMP-9: Reconditioned equipment
CMP-10: Short circuit ratings, service disconnect, disconnect for meters, transformer secondary conductor, secondary conductor taps, surge protective devices, disconnecting means generally, spliced and tap conductors, more metering safety, 1200 ampere threshold for arc reduction technology, reconditioned surge equipment shall not be permitted, switchboard short circuit ratings
