Food in … SPACE!

history, Technology

By John Dreyer

When I was in my early teens I bought Mr. Scott’s Guide to the Enterprise. This book was just a technical manual for Star Trek and, as a young fan, I was pretty happy. One aspect the authors addressed was eating on board a future starship using a replicator. Essentially a 3D food printer, the replicator could make anything you desired. The author even included a menu of choice dishes. This book is only one place where food in science fiction is addressed. From the cornbread in Aliens to the generic-looking dinner in 2001: A Space Odyssey that David Bowmen grabs while it’s still too hot, food has had a place in storytelling.

But what about real space exploration? Do astronauts get Yankee Pot Roast? Space food has had a long developmental arc, often supplemented by industry, that seeks to put nutritious and tasty food at the fingertips of astronauts and, later, consumers.

The first food in space was carried by Yuri Gagarin. His meal was two tubes of pureed meat and a tube of chocolate sauce. For the designers of the meal, there was a question if he could actually eat and digest in zero gravity. In his first American orbital flight, John Glenn consumed a tube of applesauce, which he claimed to have enjoyed. Tube foods are not exactly appetizing, and nutrition in space was still in its infancy. There were also questions of taste and texture. As NASA began to work towards Apollo and the moon landing, it was realized that better food was necessary.

High-Tech Spirits and Ghost Tours

Events, history, horror

By Laura Kremmel

The 2020 film Host (dir. Rob Savage) was recently crowned the scariest horror movie according to a scientific study that measured the heart rates of 250 viewers watching 40 different films. As someone who watches a lot of horror and is usually not affected by it, I had to turn on all the lights in my house after watching it alone on a tablet. Why is it so scary? It’s all in the technology.

The film is about a séance held by five friends and a medium, all in different locations and connected to each other not only through the medium leading them or their shared concentration but also through Zoom, a program we’ve all come to rely on to make us feel connected to each other. As the trailer asks, what if it connects us with something else?

National Hispanic Heritage Month: Celebrating Hispanic Scientists

history, race, Representation

By Christy Tidwell

National Hispanic Heritage Month spans September 15 to October 15 and is a time to, as the official Library of Congress website says, celebrate “the histories, cultures and contributions of American citizens whose ancestors came from Spain, Mexico, the Caribbean and Central and South America.” This includes important historical and contemporary contributions to STEM fields, despite the ongoing underrepresentation of Hispanic people within those fields.

Is it Hispanic or Latino or…?

The language used to refer to people “whose ancestors came from Spain, Mexico, the Caribbean and Central and South America” is complicated. Not all people included in this list would call themselves Hispanic, despite the name given to the month. Some prefer Latinx (or Latino/a or Latine), some prefer Chicano (or Chicana or Chicanx), and some prefer a more specific reference to their families’ nationality (e.g., Mexican American, Cuban American). And none of this addresses the question of indigeneity and the distinctions between histories of Indigenous peoples and colonizers in these regions. Nevertheless, given the lack of a consistent umbrella term and the name of the month, I will use the term Hispanic generally and will use other terms for individuals if they identify themselves in another way. (For more on this issue, see Vanessa Romo’s NPR piece “Yes, We’re Calling It Hispanic Heritage Month And We Know It Makes Some of You Cringe.”)

Running the Numbers

South Dakota Mines’ Hispanic student population has hovered around 5% of the total student population for the last 5 years, meaning that there have been approximately 120-140 Hispanic students enrolled in each of those years. This is not a high proportion of the overall student body, but Hispanic students still represent the largest group of students of color at Mines.

“The Oldest Profession”: Sex Work through the Lenses of History, Feminism, and Sociology

history, Sociology

By Kayla Pritchard

Prostitution (i.e., the sale/purchase of sexual services) existed in Deadwood, South Dakota, from 1876 until 1980, when the last brothel was raided by the FBI. Many of the citizens fought (unsuccessfully) to keep the brothels, seeing them as an important part of their history and the women as a valuable part of the community. Thus, 124 years of technically illegal prostitution ended in Deadwood, a town that today highly values its “wild west” past. In the fall of 2020, the Deadwood Historical Society opened The Brothel – Deadwood, a museum offering tours and interpretation, in one of the original brothels. Given my academic background, I was consulted to comment on prostitution when the museum was being constructed. Parts of my interview play on loop, along with the interviews of others, in an alcove in the museum.

Just down the road in Rapid City, I gave a talk on prostitution on August 17th for STEAM Café (that’s science, technology, engineering, arts, and math), a series that represents a partnership between South Dakota Mines and Hay Camp Brewing, offering a talk on the third Thursday of each month. Prostitution and, more broadly, sex work are often viewed as unsavory, immoral, and only something that women do out of desperation. These stereotypes are culturally pervasive, offering an overly simplified view of sex work and sex workers. Furthermore, narratives painting sex work as either empowering or exploitative also miss the point about larger systemic forces at work in the “choice” whether or not to engage in sex work. Ultimately what is missing is a sociological lens that challenges us to look beyond individuals and focus on the structures and systems around them.

Technology and Bluegrass: More Than Just the Electric Banjo

history, music, Technology

By Christy Tidwell and Matthew Bumbach

After Matthew Bumbach’s recent Brown Bag presentation on the history of bluegrass, I found myself thinking about the role of technology in the genre. I’ve long listened to bluegrass myself but have largely taken the technologies involved for granted. I wondered what we can learn about technology by thinking about its role in the arts and also what we can learn about bluegrass specifically by paying attention to its relationship to technology. To find out more, I invited him to discuss the topic.

Christy Tidwell: For any readers who may not be familiar with bluegrass, let’s quickly provide some basic information. How would you define bluegrass in just a couple of sentences? And what is the basic history of the genre?

Matthew Bumbach: Bluegrass music emerged from old time music and hillbilly string bands from the historically isolated region of Appalachia. The primary instruments in the genre are fiddle, mandolin, banjo, guitar, upright bass, and singers. Bluegrass emerged, as a genre, during the 1940s and 1950s and owes a lot of its character to the unique playing and singing of Bill Monroe, Lester Flatt, and Earl Scruggs.

CT: With that established, I’d like to focus more specifically on the relationship between bluegrass and technology. People often tend to think about technology as high-tech or futuristic, and bluegrass is not seen as either of those things. Historically speaking, what technologies were important for the creation and dissemination of bluegrass music?

MB: That is an excellent question and one that we don’t often discuss when we talk about this genre. Bluegrass could not have developed the way it did without the microphone. In the early days of bluegrass, the entire band would gather around a single microphone in both recording and live performance applications. They would create blend and balance through the use of proximity to the microphone.

The microphone was first invented and introduced to the public in 1877 by Emile Berliner, but it would be decades before we had a microphone that was effective enough to do what the pioneers of bluegrass needed. E.C. Wente invented the condenser microphone (or capacitor microphone) in 1916, a much more sensitive microphone than the earliest moving coil mics from the previous century. It took several more decades for condenser microphones to be study and cheap enough for use by the general public.

I mention the microphone as an indispensable technological advancement in the development of bluegrass music because bluegrass was professional music played by professional musicians. Unlike old time and hillbilly music that was played in churches, porches, and barns, bluegrass music developed in part because it could be played live for large audiences. Virtuosic professional musicians toured the country spreading these new sounds. Furthermore, bluegrass spread through recordings and radio. None of this could have happened without the microphone.

Who Is Earth Day For?

Environment, history

By Frank Van Nuys

In 1976 my eighth-grade science teacher gave us an assignment that seems as if it possibly aligned with that year’s Earth Day activities. I recall this primarily because of its embarrassing results. We were told to dig up some soil from our family’s yard and bring it to school to develop our own little in-door plot for growing some plant or other. Being part of the only family in southwestern Ohio not possessed of an old coffee can or some other suitable container, I dutifully filled a black plastic lawn bag with what seemed like a lot of dirt and stuffed that in a gym bag. Managing to lug my Earth Day “earth” on to the school bus, I stuffed the gym bag in my locker. When the time came for science class, I opened the locker and discovered that the plastic bag had ruptured. I suppose I somehow wrestled my embarrassingly overflowing bag of dirt into class and eventually grew something, but that sickening demoralization of middle-school level humiliation was all that really stuck with me.

My hapless effort at dirt transplantation offers a metaphor of sorts for the Earth Day phenomenon. Well-intentioned individual efforts on behalf of noble aspirations to better the planet, even if more successful than mine, amount to relatively small achievements. The first Earth Day on April 22, 1970, was certainly a masterstroke in terms of generating citizen engagement and marketing an increasingly popular sentiment into a mass movement spectacle. It can even be argued that bipartisan passage of significant federal environmental legislation, such as the Clean Air Act of 1970, the Clean Water Act of 1972, and the Endangered Species Act of 1973, fed on momentum provided by Earth Day. Additional impacts included a surge in environmental organization memberships during the 1970s and growing influence of such organizations in legal actions against corporations and government agencies.
