Owing to the proposal deadline at 5 PM EST today’s Open Office Hours will not be hosted online as usual. We are busy writing proposals. You may, however, call the office at 888-748-3670 for any question. Normal sessions resume tomorrow.
Until the Public Consultation period closes on Wednesday, June 4th EST, we will examine transcripts of previous revisions where we have an interest and prepare fresh proposals to advance our safety and sustainability agenda for educational settlements. Topmost: NFPA 70E, NFPA 72, NFPA 78, NFPA 110&111 and 1078. Complete titles are expanded in the link below.

The Temple of Zeus is a popular café located in the Groos Family Atrium of Klarman Hall at Cornell University in Ithaca, New York. Established in 1964, it began as a modest coffee and donut operation in a basement storage room in Goldwin Smith Hall, designed as a neutral space for students and faculty to meet. The café’s name comes from plaster casts of statues from the Temple of Zeus in Olympia, purchased by Andrew Dickson White in 1881, some of which still decorate the Arts & Sciences Career Development Center and Klarman Hall atrium.
Since moving to Klarman Hall in 2016, the café has grown significantly, serving nearly 900 customers daily. It offers a menu focused on healthy, locally sourced food, including creative soups (like Choklay’s Lentil, Tomato Garlic, and Curried Cauliflower), made-to-order sandwiches, salads, and baked goods. Beverages include locally roasted Copper Horse Coffee and Gimme Coffee, with a discount for bringing your own mug. The café is known for its vegetarian and vegan options, yogurt from Ithaca Milk, and seasonal fruit from local growers.
The current space is bright and spacious with 170 seats, a stark contrast to its original dingy basement setting with recycled Navy ROTC furniture. It’s a vibrant hub for students and faculty, fostering a communal atmosphere. The café employs four full-time staff, two student managers, and 50 student workers, and is managed by Keith Mercovich, who emphasizes high-quality, healthy food. It operates Monday through Friday, 8:00 AM to 3:00 PM, and is closed on weekends.
Historically, it was a gathering spot for notable faculty like Archie Ammons and Roald Hoffmann, and it remains a cherished part of Cornell’s campus culture, with a 2017 petition ensuring its name remained unchanged despite rumors of a potential rename. The café also faced a temporary closure in 2020 but reopened with a simplified menu focusing on classics like soups and scones.
For these two Cornellians, sustainable travel is in the “bag.”

Fibonacci numbers reflect standardization in nature through their consistent appearance in growth patterns and structures, embodying efficient, repeatable designs. These numbers (0, 1, 1, 2, 3, 5, 8, …) govern the arrangement of natural forms, such as the spiral patterns in sunflowers, pinecones, and seashells, where seed or scale counts often match Fibonacci numbers.
This standardization optimizes space and resource distribution, ensuring maximum efficiency—e.g., sunflower seeds pack tightly without gaps. Leaf and branch arrangements (phyllotaxis) follow Fibonacci angles to standardize light exposure and growth. The sequence’s recursive nature mirrors nature’s iterative processes, like branching in trees or cell division, providing a universal template for scalable, stable structures.
The golden ratio, derived from Fibonacci numbers, further standardizes proportions in natural forms, from nautilus shells to galaxy spirals, revealing a mathematical blueprint that unifies diverse biological and physical systems.
Fibonacci used a hypothetical rabbit population to illustrate his famous sequence in his 1202 book Liber Abaci. He posed a problem: starting with one pair of rabbits that produces another pair each month, with each new pair becoming reproductive after one month, how many pairs are there after n months? This leads to the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, …), where each number is the sum of the two preceding ones. The rabbit scenario was a simplified model to demonstrate the sequence, not a literal study of rabbit breeding. Fibonacci’s work focused on mathematical patterns, not biological theorems.
Fibonacci numbers find applications in electrical power engineering through their mathematical properties, which can optimize design, analysis, and operation. Here are five applications:
Power System Network Analysis: Fibonacci sequences can be used in graph theory to model electrical networks. The recursive nature of Fibonacci numbers helps in analyzing hierarchical or layered network structures, such as transmission and distribution grids, to optimize load flow or fault tolerance.
Transformer Winding Design: The golden ratio, derived from Fibonacci numbers, can guide the geometric arrangement of transformer windings. This helps minimize electromagnetic interference and optimize the efficiency of power transfer by balancing inductance and capacitance.
Signal Processing for Power Quality: Fibonacci-based algorithms, such as those using the golden section search, are applied in digital signal processing to analyze power quality issues like harmonics or transients. These methods efficiently identify optimal frequency components in noisy power signals.
Renewable Energy System Optimization: In solar panel or wind turbine array layouts, Fibonacci-inspired spiral patterns (like the golden spiral) can optimize land use and reduce mutual shading or turbulence, improving energy capture efficiency in power generation systems.
Control System Tuning: Fibonacci numbers can inform the design of control algorithms for power systems, such as in PID controller tuning. The sequence’s recursive properties help in iteratively adjusting parameters to achieve stable and efficient grid operation under varying loads.
These applications leverage the mathematical elegance of Fibonacci numbers to solve practical engineering challenges in power systems.
