Vandal Science News - October 2019

The Stillinger Herbarium

Research for the University of Idaho and beyond

Read Story

Dear College of Science Family,

Fall semester is well underway and the leaves are starting to change into the vibrant colors we associate with autumn in Moscow. We are lucky to live in such a beautiful area and to be associated with such a vibrant university community. I am proud to be a Vandal!

Welcome to New Faculty

The College of Science welcomed several new faculty at the university faculty meeting in September. Jim Bull, Professor of Biological Sciences, joins us from the University of Texas. Jim is a familiar face in the College of Science as he has many long-term collaborative research projects with our faculty. Jim is also a member of the prestigious National Academy of Sciences. He is the first academy member in the state of Idaho, and we are pleased that he is continuing his career in the College of Science. Jim is passionate about educating undergraduates, particularly students who are not science majors, in the practice of science, and we look forward to his new undergraduate course “Science for Non-scientists” in spring 2020.

While not new to the Department of Biological Sciences, JT Van Leuven and Jagdish Patel are newly appointed Research Assistant Professors. Both faculty members have vibrant research programs that are associated with the Institute for Modeling Collaboration and Innovation (IMCI, formerly CMCI) .

We also welcomed John Hiller, Professor and Chair of Physics. John joins us from the University of Minnesota, Duluth, as does Sophia Chabysheva, Clinical Assistant Professor, who is a researcher and instructor in the upper division physics program. John and Sophia are theoretical physicists and add to our nationally-renowned group in this research area.

Alina Andrasi is a new Instructor in our lower division Chemistry program. We are excited to have a new full-time faculty member to guide our students through their introductory chemistry courses.

This Month’s News Features

I became a scientist because I love learning about the natural world and the processes that underlie it at both the macroscopic and microscopic level. Research-based learning is certainly at the heart of our mission at the University of Idaho and in the College of Science.

To fit with our fall theme, this month we are featuring the ongoing work of a vibrant university research facility, the Stillinger Herbarium. David Tank, Associate Professor of Biological Sciences, serves as Director of the facility. The Stillinger Herbarium houses an ever-growing collection of plant and fungal specimens from across Idaho and the Pacific Northwest. It is an important local resource for U of I faculty and students from many disciplines, including biology, anthropology, history, and natural resources, as well as researchers from across the region and U.S. The herbarium collections and research activities recently moved to a newly-renovated space in the first floor of the Mines building in an effort to consolidate its work under one roof. The college is proud to host such an important and unique facility.

I hope you enjoy learning about the faculty, students and alumni who are engaged in herbarium research.

Puzzler

We’ll go to Physics for this issue’s puzzler. A rock is dropped (initial velocity zero) from the top of a tall building, and at the same instant a similar rock is thrown upward from the base of the building with an initial velocity of 50 feet per second. Remarkably, the two rocks hit the ground at the exact same instant. How tall is the building?

To solve this, remember the formula from elementary Physics: if an object is thrown upward from an initial height of H feet and with an initial velocity of V feet per second, its height (in feet) after t seconds will be given by the function

h(t) = H + Vt - 16t2

(Actually this equation disregards air resistance and assumes we are at sea level -- but it's a pretty good approximation in many cases.)


Solution to the Sept. 2019 Puzzler

There are 10 possibilities for painting the cubes. The easiest approach is simply to consider cases:

  • There is only one way to paint the cube if all six faces are going to be red.
  • Likewise, there is just one way to paint the cube if five faces are red and one is blue.
  • There are two ways to paint the cube with four red faces and two blue faces: the two blue faces are either opposite each other or they touch each other.
  • Likewise, there are two ways to paint the cube with three red faces and three blue faces: the blue either includes two opposite faces or the three blue faces must all surround one corner of the cube.
  • The remaining cases (four, five, or six red faces) simply duplicate the first three cases we examined above, with the colors reversed, so these account for 2+1+1 more possibilities.

Adding these up gives us our total of 10.

There are much more difficult variations on this problem. For instance, suppose we want to paint the 12 faces of a dodecahedron so that five are red, five are blue, and two are black. How many distinguishable patterns are there in this case? It turns out the answer is 278, but you’d not likely succeed in finding it just by counting cases as we did above. Fortunately, there are more sophisticated tools available! If you’re interested in the subject, try reading up on Burnside's Lemma.
