Norwegians in Michigan

Scholar Works: Clifford O. Davidson

The 1943 American bombing of the hydrogen plant at Rjukan Norway — so that the Germans could not make a heavy water hydrogen bomb — resembles the 2026 American bombing of Operation Epic Fury.  Inspired by Norwegian family immigration to the shores of Lake Michigan we collect stories of those families fleeing the economic hardship of their homeland before the discovery of North Sea oil.

Check Your Privilege

In the late 1960s, the discovery of massive North Sea oil reserves transformed Norway from a modest fishing, shipping, and hydroelectric economy into one of the world’s richest nations. Oil revenues funded an expansive welfare state and created the world’s largest sovereign wealth fund.  This “outsized good fortune” should temper any sense of moral or cultural superiority some Norwegians express toward America. Striking oil is no guarantee of success — see Venezuela or Nigeria. Norway also benefited from American technology, open markets, and capital.

The United States further provided critical security: liberating Norway in WWII and leading NATO during the Cold War, allowing Norway to focus on welfare rather than heavy defense.  No student debt!  Arrogance ignores contingency. Norway’s success rests on oil rents, a small homogeneous population, high trust, and luck — not inherent superiority. America’s innovations and security role helped create the global order that enabled such fortunes in Norway specifically and Western Europe generally. Recall the American role in the destruction of the German heavy water refinement plants in November 1943 (The Heroes of Telemark) which bears an uncanny resemblance to the present USA Operation Epic Fury in Iran.

Gratitude and humility suit these discussions better than condescension.

 

 

 

“Tea, Earl Grey, Hot”

The command issued by the character Captain Jean-Luc Picard in the television series “Star Trek: The Next Generation” finds its way into the archive of photographs of Nobel Laureates consorting with politicians at the University of Michigan and elsewhere.

…”There’s not good math explaining forget the physics of it.  Math explaining the behavior of complex systems yeah and that to me is both exciting and paralyzing like we’re at very early days of understanding you know how complicated and fascinating things emerge from simple rules…” — Peter Woit [1:16:00]

Coffee & Tea Standards

Since 1936 the Brown Jug has been the ancestral trough of generations of University of Michigan students and faculty — notably. Donald Glaser (inventor of the bubble chamber) and Samuel C. C. Ting (Nobel Laureate) whose offices at Randall Laboratory were a 2-minute walk around the corner from The Brown Jug.  As the lore goes, the inspiration happened whilst watching beer bubbles one ordinary TGIF Friday.

The Brown Jug is named after the Michigan vs Minnesota football trophy, which is the oldest in college football.

Food Safety

Overdoor, France, ca. 1825; | Smithsonian Design Museum

Education communities have significant food safety responsibilities.  Risk gets pushed around global food service counterparties; a drama in itself and one that requires coverage in a separate blog post.*

Since 2013 we have been following the development of food safety standards; among them ANSI/NSF 2: Food Equipment one of a constellation of NSF food safety titles whose provisions cover bakery, cafeteria, kitchen, and pantry units and other food handling and processing equipment such as tables and components, counters, hoods, shelves, and sinks.  The purpose of this Standard is to establish minimum food protection and sanitation requirements for the materials, design, fabrication, construction, and performance of food handling and processing equipment.

It is a relatively stable standard; developed to support conformance revenue for products.  A new landing page seems to have emerged in recent months:

Food and Beverage

You may be enlightened by the concepts running through this standard as can be seen on a past, pre-pandemic agenda:

NSF 2 Food Safety 2019 Meeting Packet – Final Draft

NSF 2 Food Safety 2019 Meeting Summary – August 21-22 Ann Arbor NSF Headquarters

NSF 2 Food Equipment Fabrication Agenda – FEF – TG – 2021-01-12

Not trivial agendas with concepts that cut across several disciplines involving product manufacture, installation, operation and maintenance.  We find a very strong influence of organizations such as Aramark and Sodexo.   More on that in a separate post.

This committee – along with several other joint committees –meets frequently online.  If you wish to participate, and receive access to documents that explain the scope and scale of NSF food safety standards, please contact Allan Rose, (734) 827-3817, arose@nsf.org.   NSF International welcomes guests/observers to nearly all of its standards-setting technical committees.   We expect another online meeting hosted by this committee any day now.

Keep in mind that all NSF International titles are on the standing agenda of our Nourriture (Food) colloquia; open to everyone.  See our CALENDAR for the next meeting.

Risk Assessment in Emergency Facilities

 

Critical Operations Power Systems: Improving Risk Assessment in Emergency Facilities with Reliability Engineering

University of Michigan | Ann Arbor, Michigan
HP Critical Facilities Services | Bethesda, Maryland
Mark Beirne

DLB Associates | Chicago, Illinois

Abstract. The key feature of this article is the application of quantitative method for evaluating risk and conveying the results into a power system design that is scaled according to hazards present in any given emergency management district. These methods employ classical lumped parameter modeling of power chain architectures and can be applied to any type of critical facility, whether it is a stand-alone structure, or a portion of stand-alone structure, such as a police station or government center. This article will provide a risk assessment roadmap for one of the most common critical facilities that should be designated as COPS per NEC 708-a 911 call center. The existing methods of reliability engineering will be used in the risk assessment.

History of the English Speaking Peoples

Michigan Central

Since so much of what we do in standards setting is built upon a foundation of a shared understanding and agreement of the meaning of words (no less so than in technical standard setting) that time is well spent reflecting upon the origin of the nouns and verbs of that we use every day.   Best practice cannot be discovered, much less promulgated, without its understanding secured with common language.

Tuscan Bean Soup

Standards Michigan Central | MHealthy Recipes*

Ribollita origin traces back to the Middle Ages in rural Tuscany, Italy, as an example of cucina povera (poor people’s cooking). Peasants and servants repurposed leftovers to avoid waste: after feudal lords ate meals served on large slices of bread (used as trenchers), the soaked, stale bread was collected and combined with vegetables, beans (especially cannellini), and greens like lacinato kale or cabbage. The mixture was boiled, often reboiled the next day with more bread added for thickness, improving flavor and heartiness. This thrifty habit of reheating and extending the dish gave it its name.
