Fireworks are synonymous with celebration in the twenty-first century. But pyrotechnics—in the form of rockets, crackers, wheels, and bombs—have exploded in sparks and noise to delight audiences in Europe ever since the Renaissance. Here, Simon Werrett shows that, far from being only a means of entertainment, fireworks helped foster advances in natural philosophy, chemistry, mathematics, and many other branches of the sciences.
Fireworks brings to vibrant life the many artful practices of pyrotechnicians, as well as the elegant compositions of the architects, poets, painters, and musicians they inspired. At the same time, it uncovers the dynamic relationships that developed between the many artists and scientists who produced pyrotechnics. In so doing, the book demonstrates the critical role that pyrotechnics played in the development of physics, astronomy, chemistry and physiology, meteorology, and electrical science. Richly illustrated and drawing on a wide range of new sources, Fireworks takes readers back to a world where pyrotechnics were both divine and magical and reveals for the first time their vital contribution to the modernization of European ideas.
Nitro cold brew is bubbling up in coffee shops almost everywhere. The nitrogen-infused beverage became one of the hottest new offerings for coffee lovers looking for something different. The cold brew — made by steeping coffee grinds in cold water for multiple hours — is dispensed from a stout tap, similar to what you’d find at your local bar.

Howard Zinn taught at Boston University from 1964 to 1988. His intellectual legacy has not held up well among serious historians. Zinn presented American history as a simplistic morality play of evil elites versus virtuous “the people.” Scholars across the political spectrum, including left-leaning historians like Michael Kazin and Sam Wineburg, have criticized it as a “polemic disguised as history” and a Manichean fable rather than rigorous scholarship.
The book is filled with selective quoting, decontextualized facts, major omissions, and heavy reliance on secondary sources that support his Marxist-tinged narrative. Detailed critiques, such as Mary Grabar’s Debunking Howard Zinn, document numerous factual distortions regarding Columbus, the American Revolution, slavery, WWII, and more.
Zinn openly rejected “disinterested scholarship” in favor of activism, producing advocacy rather than balanced analysis. While influential in activist and popular circles, its methodological flaws and lack of nuance have kept it outside mainstream academic respect.
Discusses the collapse of Kendi’s Center for Antiracist Research at Boston University, alleging mismanagement of $55 million with minimal research output. Describes Kendi as a “symbol of the BLM era’s destructive passions” and notes his move to Howard University.

BU’s 2024 #GivingTuesday will support several programs, including several scholarship funds and campus resources, including BU’s Newbury Center, LGBTQIA+Student Resource Center, Undergraduate Research Opportunities Program (UROP), and more.
Municipalization refers to a local governmental unit purchasing a merchant utility; a practice gathering pace in university towns in recent years. It is a very large transaction. Best practice discovery and promulgation begins with an accumulation of case studies before any concepts stabilize into a “standard”. Today at the usual hour we examine a few representative case studies. Use the login credentials at the upper right of our home page.
Abstract: This guide identifies the mechanisms and an analytic approach for developing consistent rules, agreements, and/or methodologies for the evaluation and inter-entity cooperation managing pole attachments on utility infrastructure that can contain both electric supply as well as communications wireline and wireless facilities.
The common safety codes and accepted good industry practices for joint use are referenced, including items such as clearances and strength/loading requirements, appropriate work rules during installation, maintenance and restoration, and general guidelines. The considerations within this guide can be used to help perform a detailed assessment of attachment installations where communications antennas and related wireline and wireless equipment are to be co-located on joint use structures.
Scope: This guide provides recommendations for the development of consistent guides, agreements, and/or methodologies for the evaluation and inter-company cooperation on managing pole attachments on Electric Utility infrastructure.
Purpose: The Joint Use Guide documents consistent approaches, methodologies and rules for the sharing and co-location of equipment with electric Transmission & Distribution (T&D) facilities for communications such as antennae and/or cable. With the emergence of new communications networks and emerging technologies which depend on widely distributed communications {e.g. 5G and Internet of Things ( IoT)}, the needs of vertical real-estate for use in communications is expected to dramatically increase in the coming years. While electric T&D facilities provide an excellent platform to help meet these needs, there are significant safety and reliability issues associated with their use.
This title sets the standard of care for construction, operation and maintenance of power and telecommunication infrastructure on the supply side of the point of common coupling. It is the first title to contemplate when weather disasters happen; with most public utilities bound to its best practice assertions by statute. Pre-print of Change Proposals for changes to appear in 2028 Edition will be available by 1 July 2025; with 24 March 2026 as the close date for comments on proposed changes.
The standard of care for electrical safety at high and low voltage is set by both the NEC and the NESC. There are gaps, however (or, at best “gray areas”) — the result of two technical cultures: utility power culture and building fire safety culture. There is also tradition. Local system conditions and local adaptation of regulations vary. Where there is a gap; the more rigorous requirement should govern safety of the public and workers.
The 2023 National Electrical Safety Code (NESC)– an IEEE title often mistaken for NFPA’s National Electrical Code (NEC) — was released for public use about six months ago; its normal 5-year revision cycle interrupted by the circumstances of the pandemic. Compared with the copy cost of the NEC, the NESC is pricey, though appropriate for its target market — the electric utility industry. Because the 2023 revision has not been effectively “field tested” almost all of the available support literature is, effectively, “sell sheets” for pay-for seminars and written by authors presenting themselves as experts for the battalions of litigators supporting the US utility industry. Without the ability to sell the NESC to prospective “insiders” the NESC would not likely be commercial prospect for IEEE. As the lawsuits and violations and conformance interests make their mark in the fullness of time; we shall see the 2023 NESC “at work”.
Change Proposals are now being accepted from the public for revisions to the 2023 Edition of the National Electrical Safety Code® #NESC through 15 May 2024.
The new code goes into effect 1 February 2023, but is now available for access on IEEE Xplore! Produced exclusively by IEEE, the National Electrical Safety Code (NESC) specifies best practices for the safety of electric supply and communication utility systems at both public and private utilities. The bibliography is expanding rapidly:
The IEEE NESC technical committee has released a “fast track” review of proposed changes to fault-managed power system best practice:
CP5605 Provides a definition of new Fault Managed Power System (FMPS) circuits used for the powering of
communications equipment clearly defines what constitutes a FMPS circuit for the purposes of application of the NESC
Rules of 224 and 344 https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXtAAAAADhMnPs
CP5606 Provides new definitions of Communication Lines to help ensure that Fault Managed Power Systems (FMPS)
circuits used for the exclusive powering of communications equipment are clearly identified as communications lines
and makes an explicit connection to Rule 224B where the applicable rules for such powering circuits are found. https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXpAAAAAFfvWIs
CP5607 The addition of this exception permits cables containing Fault Managed Power System (FMPS) circuits used for
the exclusive powering of communications equipment to be installed without a shield. https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXuAAAAAEEt3p4
CP5608 The addition of this exception permits cables containing Fault Managed Power System (FMPS) circuits used for
the exclusive powering of communications equipment to be installed without a shield. https://ieee-sa.imeetcentral.com/p/eAAAAAAASPXvAAAAAGrzyeI
We refer them to the IEEE Education & Healthcare Facilities Committee for further action, if any.

We collaborate closely with the IEEE Education & Healthcare Facilities Committee (IEEE E&H) to negotiate the standard of care for power security on the #SmartCampus since many campus power systems are larger than publicly regulated utilities. Even when they are smaller, the guidance in building the premise wiring system — whether the premise is within a building, outside the building (in which the entire geography of the campus footprint is the premise), is inspired by IEEE Standards Association administrated technical committees.

Today we begin a list of noteworthy changes to be understood in the next few Power colloquia. See our CALENDAR for the next online meeting.
New rules 190 through 195 cover photovoltaic generating stations. Rule 116c adds an exception for short lengths of insulated power cables and short-circuit protection if the situation involves fewer than 1,000 volts.
Rule 320B has been revised to clarify separations that apply to communications and supply in different conduit systems.
Table 410-4 is based on the latest arc flash testing on live-front transformers.
Rule 092A adds an exception allowing protection, control, and safety battery systems to not be grounded.
Rules 234 B1, C1, D1 were revised to better present vertical and horizontal wind clearances, and to coordinate requirements with the new Table 234-7.
Rule 120A was revised to provide correction factors for clearances on higher elevations.
Table 253-1 has been revised to reduce the load factor for fiber-reinforced polymer components under wire tension—including dead ends—for Grade C construction.
Rule 410A now requires a specific radio-frequency safety program for employees who might be exposed.
In the Clearances section, as well as in the specification of the Grade of Construction in Table 242-1, the Code further clarifies the use of non-hazardous fiber optic cables as telecom providers continue to expand their networks.
Revisions in the Strength & Loading sections include modified Rule 250C, which addresses extreme wind loading for overhead lines. Two wind maps are now provided instead of the previous single one. A map for Grade B, the highest grade of construction, with a Mean Recurrence Interval (MRI) of 100 years (corresponding to a one percent annual probability of occurrence) is provided in place of the previous 50–90-year MRI map. For Grade C construction, a separate 50-year MRI (two percent annual probability of occurrence) map is now provided. In the previous Code, a factor was applied to the 50–90-year MRI map for application to Grade C.
Changes were also made to the method of determining the corresponding wind loads, consistent with the latest engineering practices as an example of a Code revision focused on public safety, the ground end of all anchor guys adjacent to regularly traveled pedestrian thoroughfares, such as sidewalks, and similar places where people can be found must include a substantial and conspicuous marker to help prevent accidents. The previous Code did not require the marking of every such anchor guy.
Significant revisions were made in Section 14 covering batteries. Previous editions of the code were based on lead-acid technology and batteries only used for backup power. The 2023 Code incorporates the new battery technologies and addresses energy storage and backup power.
A new Section 19 of the code covers photovoltaic generating stations, with sections addressing general codes, location, grounding configurations, vegetation management, DC overcurrent protection, and DC conductors. These new rules accommodate large-scale solar power projects.
In the Clearances section, all rules for wireless antenna structures have been consolidated in the equipment section (Rule 238 and 239), which makes the Code more user-friendly.
A new subcommittee was created focusing on generating stations, with the original subcommittee continuing to address substations.
A working group is investigating Fault Managed Power Systems (FMPS) cables as the technology may be used for 5G networks. The team is looking at possible impacts, including clearances and work rules.
Several proposals recommending improvements to the 2017 National Electrical Safety Code (NESC) were submitted to the IEEE subcommittees drafting the 2022 revision of the NESC. Some of the proposals deal with coordination with the National Electrical Code — which is now in its 2023 revision cycle. Keep in mind that that NESC is revised every 5 years at the moment; the NEC is revised every 3 years.
The original University of Michigan standards advocacy enterprise has been active in writing the NESC since the 2012 edition and set up a workspace for use by electrical professionals in the education industry. We will be using this workspace as the 2022 NESC continues along its developmental path:
The NESC is a standing item on the 4-times monthly teleconferences of the IEEE Education & Healthcare Facilities committee. The next online meeting is shown on the top menu of the IEEE E&H website:
We have a copy of the first draft of the 2023 NESC and welcome anyone to join us for an online examination during any of Power & ICT teleconferences. See our CALENDAR for the next online meeting.
Business unit leaders, facility managers and electrical engineers working in the education facilities industry may be interested in the campus power system reliability database. Forced outages on large research campuses, for example, can have enterprise interruption cost of $100,000 to $1,000,000 per minute. The campus power system forced outage database discriminates between forced outages attributed to public utility interruptions and forced outages attributed to the university-owned power system. The E&H committee will convey some of the discipline applied by the IEEE 1366 technical committee into its study of campus power systems and, ultimately, setting a benchmark for the standard of care for large university power systems.
* The IEEE changed the nominal date of the next edition; likely owed to pandemic-related slowdown typical for most standards developing organizations.

Spoon University, a prominent online food publication for college students, was founded in 2012 by Northwestern University students Sarah Adler and Mackenzie Barth. As juniors living off-campus, they struggled to cook and navigate the food scene, noticing a lack of youth-focused culinary media. This inspired them to launch a blog combining journalism and food, initially for Northwestern students.
The platform quickly grew, engaging 100 students at Northwestern to create recipes, restaurant reviews, and food-related content. Its success led to expansion, with students from other universities requesting chapters. By 2014, Spoon University had spread to over 100 campuses globally, amassing thousands of contributors. Supported by the Techstars accelerator and later acquired by Scripps Networks Interactive in 2017 for approximately $10 million, Spoon University became a key voice in the food movement, empowering young creators

Today at the usual hour we review a selection of global building codes and standards that guide best practice for safety, accessibility, and functionality for day care facilities; with special interest in the possibilities for co-locating square footage into the (typically) lavish unused space in higher education facilities.
Use the login credentials at the upper right of our home page.
Today we break down the stack of regulations, codes, standards and open-source literature governing the safety and sustainability of university-affiliated medical research and healthcare delivery facilities. Because of the complexity of the topic we break down our coverage:
Health 200. Survey of all relevant codes, standards, guidelines and recommended practices for healthcare settings.
Health 400. All of the above with special consideration needed for obstetrics, gynecological and neonatal clinical practice and research.
We limit our interest to systems — water, power, telecommunication and security; for example — that are unique to campus-configured, city-within-city risk aggregations. Electrotechnologies (voltage stability, static electricity control, radio-interference, etc.) in these enterprises are subtle, complex and high risk. Sample titles from legacy best practice literature in this domain are listed below:
Since our interest lies in the habitable spaces for these enterprises we usually start with a scan of the following titles:
International Building Code Section 407 (Institutional Group I-2) identifies requirements specific to healthcare settings, covering aspects such as fire safety, means of egress, and smoke compartments. Maternity and obstetric facilities within hospitals fall under this classification.
A relatively new publisher of related standards is the Facility Guidelines Institute. We are monitoring its catalog and its processes. The healthcare facility industry is likely large enough for another non-profit but we have yet to see meaningful leading practice discovery and promulgation that is unrelated to the literature that is already out there.
International Conference on Harmonization: The ICH guidelines provide guidance on the development of pharmaceuticals and related substances, including clinical trials, drug safety, and efficacy.
Good Laboratory Practice: GLP is a set of principles that ensure the quality and integrity of non-clinical laboratory studies. It ensures that data generated from non-clinical laboratory studies are reliable, valid, and accurate.
