George Nissen and the Trampoline

Posted on by Amanda Bartel

George Nissen was born in Blairstown, Iowa in 1914 and moved to Cedar Rapids as a child. It was at the local YMCA that he would learn both tumbling and diving. In 1930, 16 year-old Nissen attended a circus performance where he saw acrobats falling onto safety nets, finishing their descents with somersaults. Nissen considered the opportunities for gymnasts like him using a similar apparatus. Over the next few years, he would create a few prototypes using materials he could find, including iron from the local scrapyard and his own bed.

Nissen brought his athletic and academic skills to Iowa City as a student here at the University. He graduated in 1937 with a degree in Business Studies. During his time at school, he was an active member of the Pi Kappa Alpha fraternity, a three-time NCAA gymnastics champion, and participated in the annual Dolphin Shows – aquatic showcases that featured divers and acrobatics. Upon graduation, Nissen and two of his friends joined forces as a traveling acrobatic group, utilizing the Nissen’s trampoline as part of their act. The Three Leonardo’s, as they were known, ended their touring when Nissen joined the Navy to fight in World War II. 

Nissen would receive the patent for his “Tumbling Device” on March 6, 1945, for which he would later register the trademark “trampoline,” inspired by “el trampolin,” Spanish for “diving board.” He then got to work using the knowledge from his Business Studies degree to market his invention. Some of his first buyers were the United States Military and NASA, who used it as a tool to train pilots and astronauts to quickly adapt to changing orientations. Working with Scott Carpenter, a pilot who would later become an astronaut, Nissen created a game called “Spaceball.” Check out this short video to see this fun sport that combines elements of volleyball, basketball, tumbling, and other sports.

The trampoline’s popularity would soon explode, and soon they were both exercise and play equipment. In the 1960’s, trampoline parks began to spring up, similar to those that have gained popularity in the past few years. However, these quickly gained a reputation for being dangerous, which Nissen blamed on poor training of the users, staff, and owners, and discouraged this kind of use. In 1962 the International Gymnastics Federation recognized trampolining as an official sport, but it wouldn’t be until the Sydney Olympic Games in 2000 that it would become an Olympic sport. Nissen, 86, was present to see the sport he had created bounce onto the largest stage imaginable, and was even invited to jump on the Olympic trampoline. 

Nissen passed away in 2010 at the age of 96. He had spent his entire life advocating for his invention and building a company rooted in passion. Today trampolines are as popular as ever, both in the backyard and the gym.

Snowflake Photography

Posted on by Amanda Bartel

Snowflakes are tiny works of art, and the science of snowflake photography gives us a unique insight to that world. The man who developed snowflake photography was Wilson Alwyn Bentley, known in his later years as Snowflake Bentley. Born in 1865 in Jericho, Vermont, Bentley’s research of snow and weather patterns started as a teenager, studying snowflakes under a microscope on his parents’ farm. He drew sketch after sketch of his snowflakes, but when he stumbled upon information of microscope photography, he convinced his father, who was practical to a fault, to purchase a camera with the appropriate equipment for his next endeavor. 

Snowflake Bentley photographing snow crystals. He worked quickly in a cold room or outside to keep the snowflakes from melting before he could get the photomicrograph.

It would take Bentley more than a year to find success. The ice crystals would melt quickly, and the photo developing process took a lot of time and effort, especially considering that Bentley was a newcomer to photography. After much trial and error, Bentley had success on February 15, 1885 when he got his first clear image, also known as a photomicrograph. He is quoted as saying “The day that I developed the first negative made by this method, and found it good, I felt almost like falling on my knees beside that apparatus and worshiping it! It was the greatest moment of my life.” Because of his lack of education, Bentley felt his contributions were unworthy of note. Eventually, he met a local professor, who convinced him to submit his first article “A Study of Snow Crystals,” which was published in 1898 in Popular Scientific Monthly.  This opened to floodgates, and soon he was publishing articles and traveling the country to give presentations. 

Even living in snowy New England, he couldn’t work with snowflakes year-round. He eventually expanded his studies to include other precipitation, including rainfall, mist, and dew, but snow remained his passion. In 1931, he published his life’s work Snow Crystals. This book included almost 2,500 photomicrographs of snowflakes. If you’re interested in seeing Bentley’s work, you can see some of his photomicrographs through the Smithsonian’s online collections, or you find a copy of Snow Crystals at the Science Library. Later that year, Bentley caught pneumonia and passed away at home on December 23rd, 1931. 

A photomicrograph taken by Bentley

Bentley created his photomicrographs by capturing the snowflakes on white velvet, then scratching the emulsion off the plate to create the back background. This allowed Bentley to edit out non-symmetrical parts, which contributed to the myth that all snowflakes are completely symmetrical. Our current technology allows for more accurate images of snowflakes. With a willingness to stand outside and a DSLR camera (which you can check out from our tool library), and a macro lens, you too can take your own stunning snowflake photographs! If you follow photographer Craig Goodwin’s advice, the process of snowflake photography hasn’t changed much from Bentley’s time. If you want to read more about Goodwin’s process, you can find his blog post here. If you’re not a photographer, or aren’t interested in sitting outside to catch snowflakes, you can see some great flakes in The Art of the Snowflake: a photograph album by Kenneth Libbrecht, available here at the Engineering Library.

Snow Engineering

Posted on by Amanda Bartel

Now that we have entered the snowy time in the year, we might as well embrace the snow. Although we may not see snow as a positive thing, there are many cultures that take advantage of its unique properties. The Inuit peoples of North America and Greenland use snow to create igloos, also spelled “iglu.” This form of shelter is also sometimes known as an aputiak. These temporary buildings are built entirely of snow, and are usually used as hunting lodges.

 

Inuit Village, Oopungnewing, near Frobisher Bay on Baffin Island in the Mid-19th century

 

While a structure made out of snow may seem like a chilly prospect, but they Inuit hunters could stay in their igloos for entire winters quite comfortably. Not only does the igloo block cold wind, the densely packed snow acts as an insulator to keep those inside warm. In fact, the longer an igloo is used, the more durable it becomes! As people move around inside the structure, the snow melts but refreezes as temperatures drop, creating thin layers of ice. In fact, a well built igloo can support the weight of an entire person. 

But how are igloos built? The main component needed is packed snow. Most snow that falls from the sky in Iowa isn’t going to be dense enough. If you want the appropriate building material you’ll either have to move north – at least to Northern Minnesota. If you find a snow bank that has been packed by wind, you may be able to cut it out and use it, but you will likely need to put in some extra work to pack snow to make blocks. 

Once you choose how large you would like your structure to be, you can begin building. These blocks should not be completely square, but wedge-shaped. This, combined with building in a spiral allows for a self-supported dome. If your dome is completely semi-circular, not all of the blocks share compressive forces, making it more likely to fall. Instead, build your igloo to be a parabolic or catenary arch, more egg-shaped than the dome on the Old Capitol. If you want all the ins and outs of the project, come in and check out How to Build an Igloo and Other Snow Shelters by Norbert E. Yankielun.

If you don’t think you can make your own igloo from scratch, you don’t have to be completely kept out of the fun. A Canadian company called PlaySnow makes igloo-shaped support structures that can be covered in snow to make a structure that is sturdy and safe from collapse. They are designed for children, so take that into consideration before you purchase one for your wintertime fun, since a too-small igloo is uncomfortable.

Coast into Winter Fun

Posted on by Amanda Bartel

You’re almost done with the semester, and soon you’ll have time to go outside and enjoy the snow. Have you ever thought about the history of sleds? 

Sled race, anyone?

Sleds have a very long history, helping us to work and play. You may have spent your snow days gliding downhill on a plastic saucer or an innertube style sled. The story of the Flexible Flyer is one of engineering, redesigning, and risk.

The Flexible Flyer

Samuel Leeds Allen loved winter activities. From “coasting” (the term used for downhill sledding in the Victorian  era), to ice skating, it was difficult to keep him inside during the Philadelphia winter. During his childhood, toboggans were the most common version of a sled. Having no runners or brakes, riders had to dig a heel into the snow to turn or stop. He was also a tinkerer from a young age. His mother was quoted as saying “I never saw anyone with such perseverance. He never seemed to give up on an idea.” Allen’s teachers believed him to be lazy because he didn’t engage well with the lessons, preferring experiential learning over rote learning. 

After leaving school, Allen moved to live with a relative on a farm in New Jersey. It was there that he started making improvements to farming implements. Eventually he created his own company, S.L. Allen & Co., which made seeders, hoes, plows, harrows, corn shellers, feed grinders, and lawn mowers, among other things. He worked hard to cultivate relationships with buyers, and utilized advertisements in existing publications as well as creating his own. Allen also thrived because of patents and the protection of intellectual property they provided. 

While enjoying sledding with his daughters, Allen’s mind turned to improving the experience. His daughter remembers having to sled down hills again and again and reporting every thought about the ride. Eventually, he would patent his first sled in 1887 called the “Fairy Coaster.” It was large enough to hold three riders on its padded seat, and was steerable with a braking system. However, at $50, the price point was out of reach for most consumers. It was an absolute failure. 

Patent 408,681, the Flexible Flyer

Allen learned from this episode, and worked to improve his design. In 1889 he would be awarded his second patent, this time known as the Flexible Flyer. Again, it looked like the product would be a failure. For several years, Allen’s sled would again fail to sell significant numbers. It wasn’t until people started getting more free time in the mid 1890’s that they had time to enjoy sledding. By 1910, the Flexible Flyer would become the most popular brand, with distinctive branding and features. You can even get your own Flexible Flyer today! 

Sledding on Sand

Maybe your winter plans include more tropical climates – you can still sled! Did you know that some of the first sleds were used on wet sand? There is evidence that the Ancient Egyptians used sleds to efficiently move large blocks of stone. I’m sure you could also take a snow saucer down a sand dune.

The native peoples of Hawaii also have their own version of sledding, called hee holua, or “sled riding.” 12-foot long wooden sleds are ridden down a kahua holua (sledding course), which is made out of lava-gravel. Riders usually ride the sled lying down face first, standing up, or kneeling. Speeds can reach 50-80 miles per hour! 

Sledding on Flat Land

Sleds are also helpful tools to move across flat snow-covered land, but you’ll need some extra power. Dogsledding is one method, utilizing special breeds of dogs who have strong legs and thick coats. Today most of us are most familiar with the Iditarod, a race between Anchorage to Nome, a distance of 938 miles that typically takes 8 to 15 days. This race commemorates the “Great Race of Mercy,” a rush to get diphtheria antitoxin to an ice-bound Nome in the winter of 1925. The serum was transported by relay, and most of the dogs in the original effort ran an average of 31 miles. 

Balto was the lead dog when his owner Leonhard Seppala delivered the serum to Nome

If you don’t have a team of dogs, you can simply kick yourself to your destination. Resembling dogsleds, kicksleds are found in Northern Europe, and work exactly how you think they would. The user stands on the back, and simply kicks to create forward momentum. They were most popular in the mid-2oth century, but you may see some around if you visit during kicksledding weather. Because the runners are very narrow (think ice-skates), they work best on ice or very hard snow.

This model looks like she’s getting some real speed using her kicksled.

What do you think now? Will you be sledding this winter? Share your tips and tricks with us below!

Gingerbread Engineering

Posted on by Amanda Bartel

Snow will soon be here and it’s time for wintertime traditions – which includes gingerbread creations! National Gingerbread House Day is December 12th. Early history of the recipe is hazy, and may range to as far back as Ancient Greece in 2400 BCE to France in 992 AD. Early on, gingerbread was used in religious ceremonies or as a digestive aid. Gingerbread cookies as we now usually enjoy them, in fun shapes with decorations is usually credited to Queen Elizabeth I, who asked for cookies to be made in the shapes of visiting dignitaries. Gingerbread was incredibly popular across medieval Europe, and there were even Gingerbread Fairs to attend where you could enjoy gingerbread shaped according to the season – flowers for springtime, and birds in the fall. Because of tall of the spices required in the recipe, gingerbread was considered very high class, and those rich enough to have it in their own homes would sometimes decorate it with gold leaf. 

The Germans began building gingerbread houses in the 16th century, and the practice became more widespread after the Grimm Brothers popularized Hansel and Gretel in 1812. Since then, gingerbread projects have turned into feats of engineering. The current world record holder for the largest gingerbread house was created by the Traditions Golf Club in Bryan Texas. This house covered 2,500 square feet, required 1,800 pounds of butter, and 1,080 ounces of ginger. It was so large that it required a building permit! If you don’t have the space to try your hand at breaking this record, maybe you can try breaking Jon Lovitch’s record for the largest gingerbread village. Lovitch’s latest record-holding village (he has held the world record 4 times) contained 1,251 structures. If you try to break a record, be careful! The rules are very specific. One recent attempt was disqualified because it contained non-edible components. 

Want to make your own gingerbread house to celebrate National Gingerbread House Day? Here are some tips:

  • Use a European recipe for your cookies. American gingerbread recipes tend to be softer, which is great for cookies, but not very helpful structurally. You can learn more about the chemistry of baking in Cooking For Geeks, which can be found in our collection. Check it out here!
  • Use a thick royal icing as your mortar. Finding the right consistency can be difficult, as it needs to be runny enough to easily spread, but thick enough to stay put. 
  • Don’t be afraid to use support! While using an internal support will disqualify you from earning any world records, but you can use a can of beans to help prop up your walls while the icing dries can ensure that the icing is able to dry in the correct position and free up your hands to move onto the next part of your project.
  • Plan ahead! Use your engineering skills to set yourself up for success. 
  • Get Creative. You don’t have to make a candy-covered cottage. Search online for fun ideas. Add lights, or try a different shape. See below for some examples:
Elevate things with a gingerbread treehouse

 

Recreate your favorite famous buildings in cookie form

 

A geodesic home would be a fun and challenging build

 

No need for your house to stay in one place. A gingerbread camper is a great idea!

Personally, I want to see Kinnick Stadium made out of Gingerbread. Are you up to the challenge? If you build a gingerbread creation, show us!  You can send it to us on any of our social media channels @uienglib on Facebook, Instagram, or Twitter.

Happy Native American Heritage Month!

Posted on by Amanda Bartel

November is Native American Heritage Month, so let’s celebrate some Native American Engineers!

Ely S. Parker (1828-1895)

Ely S. Parker (1828-1895) – Seneca, Civil and Military Engineer

Born in 1828 on the Tonawanda Indian Reservation, Ely S. Parker lived up to his Seneca name of Do-ne-ho-ga-wa, which means “Open Door.” When doors were closed to him because of his background, he found ways to open them. After unsuccessfully lobbying for the rights of his people to stay on their reservation, Parker began to study law in the hopes of advocating for the Seneca. However, when he applied for admission to the bar, he was denied because he was Seneca, and was therefore not considered a citizen in the eyes of New York State law (a law that would stand until the Indian Citizenship Act was passed in 1924). 

Never one to wait for an opportunity, Parker began to study civil engineering at the Rensselaer Polytechnic Institute in Troy, NY. This gave him the skills to work on maintenance work for the Erie Canal, and eventually move to Galena, IL to work for the Treasury Department building a custom house and marine hospital. It was there that he became friends with Ulysses S. Grant. When the Civil War began, Parker gathered a group of Iroquois volunteers for the Union, but they were turned away by the Governor of New York, Edwin Morgan. Parker then attempted to enlist by himself as an engineer, but was again denied because of his race. Finally, Parker reached out to his friend Grant, who brought Parker onto his staff in 1963. He would go on to make major contributions at several battles, including Vicksburg, Chattanooga, and Petersburg, and would help in drafting the surrender documents at the Appomattox Court House in 1965. 

After his military service, Parker became the first Native American to hold the office of Commissioner of Indian Affairs from 1869 to 1871. He would eventually return to engineering with a position in the New York City Police Department, where he served until 1895.

Mary Golda Ross (1908-2008)

Mary Golda Ross (1908-2008) – Cherokee, Aerospace Engineer

Mary Golda Ross was born in 1908 and grew up in Park Hill, OK. A member of the Cherokee Nation, Ross grew up in a tradition that prized equal education for both boys and girls. Because of this, she was not intimidated by her surroundings when she entered male-dominated fields. She started college at the age of 16 at Northeastern State Teacher’s College in Tahlequah, OK where she studied mathematics. Following graduation, she would spend several years teaching math and science in rural Oklahoma, using her summers to attend classes at Colorado State College of Teaching where she was earned a master’s degree in mathematics in 1938.

In 1942 she was hired at Lockheed Aircraft Corporation as a computer where she completed complicated mathematical equations using only a pencil, paper, and slide rule, and was assigned to the team that designed the P-38 Lightning. After the war, many of the female computers were laid off and returned to their traditional roles. Ross had drawn special attention for her ambition and abilities, and as a result was kept on and began to take courses at the UCLA to earn her professional certification in engineering. This course included classes in math, engineering, and aeronautics. During peacetime, the Advanced Development Projects team with whom Ross worked, turned to loftier goals. Also known as Skunk Works, many of this team’s projects are classified even today. Ross was a founding engineer of this team, as well as the only woman besides the team’s secretary, and the only Native American. It is known that during this time Ross worked on the Space Race, developing preliminary requirements for spacecraft, which laid the groundwork for the Apollo program. While Ross always had a fascination with space and was an advocate for female astronauts she had little interest in being one herself. She said “I’d rather stay down here and analyze the data.” 

Ross retired from Lockheed at the age of 65, but would work for many years to encourage women and Native Americans to enter STEM fields. In 2004 she was honored at the opening of the Smithsonian’s National Museum of the American Indian, which she attended wearing a traditional Cherokee dress that was made for her by her niece. She died in 2008, just three months shy of her 100th birthday.

New Sound Recordings Exhibit in the Library!

Posted on by Amanda Bartel

This week’s blog is from Keegan Hockett, who curated this exhibit. Keegan Hockett is a graduate music student pursuing his Doctor of Musical Arts degree in Bassoon Performance and Pedagogy with a secondary area in musicology. He also works as a research assistant for the Office of Community Engagement, finding opportunities for UI students who wish to engage with their local communities.  

Listening to recorded music in our day and age is a simple process that is easy to take for granted. For many of us, it looks something like this: 

 

Step 1: Choose your preferred device 

Step 2: Open your music library or favorite streaming service 

Step 4: Search for a band, song, genre, etc. 

Step 5. Hit Play 

 

Digital audio formats allow music to be at our fingertips, but this ease of access has been a long journey in the making – sound could be recorded and reproduced as early as 1877! Early recordings were made using an analog, mechanical process, but these “records” had many limitations. Sound quality, storage capacity, and longevity have all improved through engineering innovations, whether they be electrical, chemical, or mechanical. Some recordings formats were short-lived and have been largely forgotten but others remain ubiquitous in contemporary culture. Vinyl records, cassette tapes, and CDs are made of different materials, have different forms, and work in different ways, but each are capable of holding sounds captured from a moment in time. To learn more about how these formats work, check out the Lichtenberger Engineering Library’s newest exhibit on recording technologies! Additional resources on acoustics and sound engineering are available in our stacks downstairs.

Open Education Resources and the 5 R’s

Posted on by Amanda Bartel

One of the best kept secrets of education are Open Educational Resources. The University of Iowa’s adopted definition is: “Open Educational Resources (OER) are teaching, learning, and research resources that are free of cost and access barriers, and which also carry legal permission for open use. Generally, this permission is granted by use of an open license (for example, Creative Commons licenses)” These can be videos, images, and audio recordings that can be used to enhance your teaching. You may already be using them – like TED Talks, or images from Flickr! 

OER make teaching accessible, but you aren’t limited to using resources in the way they are found. Because of their public domain or creative copyright licenses, users are able to use them for the 5 R’s: Retain, Reuse, Revise, Remix, and Redistribute. From the UI LibGuide on OER these are defined as:

  1. Retain – the right to make, own, and control copies of the content (e.g., download, duplicate, store, and manage)
  2. Reuse – the right to use the content in a wide range of ways (e.g., in a class, in a study group, on a website, in a video)
  3. Revise – the right to adapt, adjust, modify, or alter the content itself (e.g., translate the content into another language)
  4. Remix – the right to combine the original or revised content with other material to create something new (e.g., incorporate the content into a mashup)
  5. Redistribute – the right to share copies of the original content, your revisions, or your remixes with others (e.g., give a copy of the content to a friend)

By contributing your remixed work to OER resources, you can help further the cycle of Open Access. What are some ways you have used OER? Let us know in the comments below!
