Learning in many ways
There are a couple of sayings Jake uses in Thermo — “Once you know entropy, it’s irreversible.” “The irony of entropy is that there are so many ways of understanding it.”
In this section we’ve included links to the course materials in many of his classes. But that’s just the beginning. We came to a research university not for the classes, but to apply those classes through real hands-on research. The learning curve to get involved in HYPER research is steep. So we’ve included a lot of the information and trainings here.
There is so much to be learned from HYPER and our lab members. From thermodynamics to research tips and tricks, cryogenics to rocket design, and much more, we love to share with you what we have learned.
You had an idea! Now what?
It’s awesome when it happens. A new concept or idea for something to solve a problem for yourself or someone else just popped into your head (more on that here). For me the hair stands up on my neck and I want to run to the nearest person and tell them the idea and why it’s important. Evidently I have a crazy look on my face when this happens because it’s scared people before. Here’s the deal — excitement like this is contagious, and unless you’re careful to get your ducks in a row, it could lead to false hope/promises and unmet expectations.

Visualizing density changes with a DSLR Camera
“Tell me what this image is.” I peered closer at the amazing image Jake was showing me. “Displacement?” I guessed nervously, glancing furtively at the inquisitor. “Not quite. Density,” Jake said. This was my interview, to which I had been 15 minutes late and in which I was already sweating profusely. I was in the deep end. Here is the image he showed me:
I was hired to the HYPER Lab despite my blunder, and worked on the Core Team (previously the General Team). By the time this project opportunity surfaced, nearly 6 months had passed since my interview, and the concept of Schlieren … » More …Read Story
How to Procure Parts Easily and Efficiently – The HYPER Way
Have you ever had a $45,000 piece of equipment show up in your facility, and thought: “I don’t remember what this is for…”? Well, I had this exact thing happen to me. I was fortunate in that the 900 pounds of equipment sitting in the shipping bay was a simple mix-up with the company delivering our equipment. Crisis averted! However, in many instances mistakes like this can lead to the loss of funds, and sometimes even jobs. The responsibility often falls to project managers to have a crystal-clear picture of the flow of parts and equipment coming in for their systems.<p style="text-align: ... » More … Read Story
How to make cryogenic Multi-Layer Insulation (MLI) shields
The Multi-Layer Insulation (MLI) Shield (aka thermal radiation blanket) is very important in cryogenic systems. MLI shields insulate components from thermal energy transferred via light on rockets, satellites, and cryogenic experiments. The shield consists of 10s of alternating layers of polymer mesh and reflective mylar (metalized nylon) film. To understand how MLI blankets work, consider an equation approximating the resistance to radiative heat transfer:
R_rad= 1/(A_s σϵ4(T_s^2+T_sur^2)(T_s^2+T_sur))
where As = radiating surface area, σ = Stefan-Boltzmann constant, ϵ= emissivity, Ts = the absolute surface temperature, Tsur = absolute surroundings temperature. Or more generally: q” = σϵ(T_sur^4-T_s^4) assuming the surface is at lower temperature … » More …Read Story
Getting Back to Work…At Work (The HYPER Guide to Returning to the Lab Safely)
A new semester has begun, and research is kicking into high gear…but we are not operating under normal conditions. The pandemic has laid new challenges at our feet which has completely changed how we approach even the simplest of tasks. It is important, now more than ever, to band together as a lab community and apply HYPER ethics to tackle these obstacles.
As quarantine restrictions loosen in our state and we can begin returning to work, we have created a plan for returning to work that will help us to stay on track with our research goals while maintaining high safety standards to prevent the … » More …Read Story
How we made (and remade) the HYPER community website
It took 10 years for me to start calling the HYPER laboratory a community. In one month we’ll have had a website for six of those ten years. In many ways those first six years were much like the six year tenure process we follow as faculty. While we’ve continually added content (>300 posts and >75 pages) within our core themes of Research, Teaching, and Service, we’ve never really sat back and thought about how to make the site truly great. This post tells the story of how the site evolved, from starting as one of the ‘guinea pig’ sites my neighbor friends (Steve Locker … » More …Read Story
