On Thursday, January 29, 2015 the third installment of JMuse Café's series, Demystifying the Expert, took place. Through teaming up with physics professors Anca Constantin and Klebert Feitosa to present this series, JMuse Café  has been able to close the gap between scientists and the JMU public. This is done through back-and-forth guessing, joking, and discussion of the expert's expertise between our hosts (Constantin & Feitosa), the expert, and 4 members of JMU's only improv comedy group New & Improv.'d. As I mentioned in the post about the most recent event, the format for this series was borrowed from a Boston NPR show entitled You're the Expert.

Our expert this event was Jason Rosenhouse, a professor of Mathematics at JMU. As one of the hosts aptly pointed out at the beginning of the show, JMuse Café could easily run at least 4 events focused on Rosenhouse (further speculation has led me to believe that 4 events may still not be enough, considering his potential for both engaging and entertaining the public); unfortunately, we only had one. Before coming to JMU in 2003, he spent three years at Kansas State University after earning his Ph.D. in Mathematics from Dartmouth and his B.S. from Brown. In addition to a number of publications pertaining to his research, Rosenhouse has authored 3 award-winning books (all of which found their way into my Amazon shopping cart while I wrote this...).

Before giving away too much about our expert, it's important to acknowledge the panel of comedians whose job it was that evening to try to extract that information from him. Trevor Knickerbocker is a senior intelligence analysis major, currently enrolled in one of Dr. Feitosa's classes. Despite this, he still maintained that Feitosa didn't feed him any information about the expert. Amanda Anzalone is a junior media arts & design major double-minoring in  French and creative writing. She may have gotten answers wrong, but at least she could do so in two languages. Business major Mikail Faalasi came to this series with his knowledge of science limited to the science of making money. Lastly, Logan Brown is a junior theater major whose answers were both comedy (for the audience) and tragedy (for him).

Following the same outline as previous events in the series, the evening consisted of several games with time for discussion in between. To jumpstart an evening consisting primarily of the expert getting bombarded with questions, Rosenhouse was given the opportunity to ask the panelists a question: What is mathematics? While the panelists were technically correct in saying that math is "NUMBERS", "and some letters", "and some imaginary things", the correct answer was in fact, "a chick magnet."

In the first game, the panelists are given the opportunity to bombard the expert with 20-questions-style questions. During this time, the audience was able to gain long lists of things Rosenhouse does and does not do. On the former list are things like, theoretical math, getting cramps from writing theoretical math, graphs, solving equations, spending time inside, and escaping life. Of the latter, we learned that Rosenhouse does not apply his math to a "field" of study, because, as he mentioned earlier, he does not go outside.

What really sparked Rosenhouse's interest in math was a day in 6th grade when he was faced with the first theorem that was not obviously true to him: the Pythagorean theorem. He remarked that his teacher at the time just threw it up on the board without proving it, and this both impressed him and caused some skepticism. It was then that he saw that math is more than what most people think it is.

At this point, Rosenhouse surely made math-lovers out of anyone in the audience who was not one already; he pointed out that people who say they don't like math, simply don't like arithmetic, but the subject itself is,

    A combination of art and science and beauty - it's the exact opposite of memorizing rules - it's discovering them and proving them.

He went on to comment that people who think that math is fundamentally about calculating things have missed the point entirely; it's about observing the beauty of math. For mathematicians, the fact that math is useful is simply a bonus on top of everything else math is. Rosenhouse commented, "We can make money and go back to our little enclaves to do math!"


Throughout the evening, there were brief discussions of the three books Rosenhouse has authored. The first book he discussed was The Monty Hall Problem: The Remarkable Story of Math's Most Contentious Brain Teaser. The Monty Hall problem was inspired by a game show where contestants are faced with 3 doors, one of which has a prize behind it. After choosing one door, the host (aware of what lies behind each door) opens one of the doors that does not contain the prize, giving the contestant the opportunity to change his or her guess now that the odds of guessing correctly have changed. The "problem" behind the Monty Hall problem, is whether or not being able to change guesses actually makes a difference. In addition to the mathematical implications of the problem, there are also psychological aspects of it as well. Secondly, Rosenhouse discussed a book he co-authored with Laura Taalman, another professor of Math at JMU: Taking Sudoku Seriously: The Math Behind the World's Most Popular Pencil Puzzle. This book addresses the questions mathematicians have about sudoku puzzles (which,  contrary to popular belief, do require math to solve - just not arithmetic). On a topic not wholly unrelated to math, his third book, entitled Among the Creationists: Dispatches from the Anti-Evolutionist Front Line. On this topic, Rosenhouse said,

            The evolution debate is where scientific ignorance has consequences – the earth isn’t 6,000 years old. These people don’t know what they’re talking about. They reference math and science and they whip out equations, but if you know anything, you know they’re wrong. Yet, they’ll say it with confidence. You have extreme insularity – that’s the problem. People will tell them what they want to hear as if it validates their opinions.

Throughout the following games, the audience and panelists gained further insight into the specific work Rosenhouse does concerning Kayley graphs, sexy primes, and the Cheeger constant. They also got to know a lot about the expert as a person. His favorite plant is the rhododendron, and he may well be the only person who thinks clowns are funny, not creepy.  But beyond that, he quite possibly one of the most quotable people we've seen in this series. When asked what he believed the meaning of life to be, he promptly replied,

    Find something you enjoy doing and leave your little corner of the world better for having done so.

As evidenced by last Thursday's evening of comedy and mathematical discussion, it is obvious that he certainly has accomplished that and probably more. If you were unable to attend this past event (as well as the two before that) you have truly missed out. But there is still one more chance, so be sure to join us in the flex space of Rose Library at 6:30 pm on February 26, 2015 as we bring this series to a close!

2 Physics & Astronomy Faculty Proposals Selected!

This year JMU organized a new way to fund faculty initiatives through the MADISON TRUST INNOVATION GRANT.  The call for proposals was sent out in August 2014; 55 responses were received, and 12 proposers were called to present their project to the Madison Trust Principal Investors on Friday, November 14, 2014 in the President’s Board Room.  Of the 12 presenters, two of them came from the Department of Physics & Astronomy! Shanil Virani, Director of the John C. Wells Planetarium, and Dr. Giovanna Scarel.  Mr. Virani presented a project entitled “STARRY NIGHTS JMU: What do we lose when we lose the night” (in collaboration with Dr. Paul Bogard in the Dept. of English), while Dr. Scarel presented “From JMU to the World: embracing the need of new energy sources”.  Both Projects received funding!

The presentation of Dr. Scarel describes the work she and her students do at the Department of Physics and Astronomy, in investigating a new method of harvesting radiation to be transformed into usable electricity.  It is called Infrared Power Generation.  The Group has published various papers with the JMU students as as first authors.  The work has attracted the attention of a research group in Finland headed by Prof. Maarit Karppinen at Aalto University that asked to collaborate.  The Group has engaged research with the Center for Nano-phase Materials Sciences at the Oak Ridge National Laboratory (TN) where the students traveled twice with Dr. Scarel in 2014.  Recently the U.S. Office of Naval Research funded one of the Group’s research projects on Infrared Power Generation.  As part of the activities of this project, the group is planning a Workshop entitled “Infrared radiation, thermoelectricity and chaos”.  The Workshop will take place at JMU on June 17, 2015.  This event will contribute to giving to JMU international visibility in research on energy-related topics.  Two of the invited speakers are from California, one from Mexico, and one from Italy.  The students, as well as the JMU 4-VA Consortium, and the JMU Office of Research and Innovation, will be part of this event.

We just don’t see a dark, starry night the way Americans 2 generations ago would have seen. In fact, it is estimated that 98% of Americans will never see the Milky Way Galaxy, our home in the Universe. Does it matter? What do we lose when we lose the night? “Starry Nights JMU” is a dynamic a new program that will make James Madison University the leader not only in Virginia but across the country in energy-efficient lighting that improves student and citizen safety, preserves human and environmental health, and brings back the beauty of the night.

Shanil Virani, Director of the John C. Wells Planetarium

“Starry Nights JMU” is designed to address the many serious—and, for the most part, unnecessary—consequences of light pollution. Defined as the overuse and misuse of artificial light at night, light pollution wastes energy and money, negatively impacts human and environmental health, and reduces our safety at night. For example, we waste more than $110 billion worldwide, and increasing numbers of studies show a link between light at night and cancers of the breast and prostrate. All of us benefit from light at night, and the question isn’t if we will use it but how. “Starry Nights JMU” exists to raise awareness that light pollution is well within our ability to solve. And now is the time. After a century of electric lighting, our society is moving toward electronic (LED) lighting. By acting now, we can recognize the energy-saving benefits of this new technology, rather than see the problems caused by light pollution grow worse. A Madison Trust Grant would allow us to act by taking following steps:
  1. campus-wide lighting assessment.
  2. retrofitting lights on campus and in the Edith J. Carrier Arboretum.
  3. establish demonstration plot of LED lights on campus.
  4. expansion of “Starry Nights” events in 2015.

JMU Ladies Represent Women in Physics

Over the weekend of January 16th-18th, @JMU #Physics was represented at the 10th annual Conference for Undergraduate Women in Physics (#CUWiP) at Duke University in Durham, North Carolina. The ladies joined women from all over the region at the research triangle, where they attended talks and presented research in all areas of physics.

From the left, Hannah McFarland, Nicole Creange, Alexandra Iuga, Catherine Witherspoon, and Keely Criddle.

As pictured above, undergraduate women from physics (Alexander Iuga, Catherine Witherspoon, Nicole Creange, and Keely Criddle) and biology (Hannah McFarland) attended and presented their research at the conference this weekend in the subject areas of condensed matter physics, astronomy, biophysics, and soft condensed matter. This was a great opportunity for the women of the JMU Department of Physics and Astronomy to meet and talk with women from all over the region about the careers in physics in academics and industry.

Keely presented a talk on her soft condensed matter research with Dr. Feitosa on the mechanical properties of hydrogel beads. We have no picture of this because Keely's talk was so awesome and they forgot to take one.

Nicole (below) presented at poster on her computational condensed matter research with Dr. Haraldsen and Dr. C. Constantin on understanding the optical properties of Ga-doped graphene.

Rebecca Kamen: Combining Art & Science

Photo from The Breeze
Kamen's piece "Fluid"
It's the week before finals, and as we prepare for the end of the semester, the stress can be overwhelming. If you're looking for a more cultural way than Netflix to escape the struggle of last-minute final preparations, I implore you to visit the Duke Hall Gallery and see the Rebecca Kamen Exhibit. Kamen's work aims to explore the connection between art, philosophy and spirituality, and a wide range of sciences, including chemistry, physics, and cosmology.   The exhibit will be open to the public until Friday, December 5 at 5:00 PM.

If you can't make the time to visit the exhibit, be sure to check out her website or the post about her on the JMU page. There you can find pictures of her work (although I strongly recommend seeing them in person!). For further information at current and future exhibits at the Duke Hall Gallery, visit their Facebook page.

Demystifying the Expert - Chris Hughes

From left to right: Hosts Klebert Feitosa & Anca Constantin, Expert Chris Hughes, Panelists Trevor Knickerbocker, Keri DeTullio, Alan Chen, & Shelby Imes
On Thursday, November 6, 2014 JMuseCafé held the event of the semester. In case you hadn’t noticed, this year’s JMuse Café events have a bit of a new format with the recent collaboration with JMU Physics & Astronomy professors Anca Constantin and Klebert Feitosa. If you attended either of the events (or read my post about the first one) you would know them as the hosts of the Demystifying the Expert series: four events intended to bridge the gap between the science faculty and the JMU/Harrisonburg community. Each event is comprised of the hosts, an expert, and a panel of four comedians from New & Improv.’d working together to figure out what the expert’s expertise is through a series of games and discussions. Though this new format came with the new hosts, they can’t take all of the credit   - the series is based on a Boston NPR radio show entitled You’re the Expert.
Our Expert of the Evening, Chris Hughes
For the event on November 6, our expert was Chris Hughes, a professor in the Physics & Astronomy department and the director of the center for Material Science at JMU. In the following sentences I’ll iterate the only background information our panel was given before trying to discern Hughes’s expertise. He received his Bachelor’s in Science from Davidson College and his Ph.D. from UNC – Chapel Hill. He did some post-doctoral work at NC State University before coming to JMU in 1997 (making him the second most senior member of the department’s faculty). He has served as a council member for the Council on Undergraduate Research (CUR), spending one term on the board as the chair of the physics and astronomy division. He has received two CSM awards: the Distinguished Teacher award in 2008 and the Distinguished Service Award in 2013. While not a dancer himself, Hughes has taught three semesters of the Physics of Dance as a GSCI 104 class as well as countless semesters of GSCI 121. His enthusiasm for teaching the Physics of Dance comes from his wife (who was a dance major in college) and his two daughters who have taken many dance classes. Donning a baseball-themed tie and having brought a bag full of baseball bats, the panel knew baseball would inevitably be a topic throughout the evening. However, Hughes can’t really play baseball. Despite this, he has been on the board of the Harrisonburg Little League Association for the past five years.
As I said earlier, the panel of comedians comes from New & Improv.’d – JMU’s only improvisational comedy troupe, bringing laughs to JMU since 1998. You can see them perform at TDU, for other JMU events, and around town at local venues. On the panel for this event we had Trevor Knickerbocker (a senior Intelligence Analysis major who mistakenly took a Quantum Physics class for fun), Keri DeTullio (a senior Media Arts & Design major who does things wholly unrelated to science), Alan Chen (a sophomore Physics major who hoped his major would be more helpful this time around), and Shelby Imes (a freshman who was so proud of finding the event that she couldn’t care less about anything else). While not on the panel, the audience was joined by two other members of New & Improv.’d, Amanda Anzalone and Macy Pniewski.
Before jumping into the first game, the expert was given the opportunity to ask the panelists a question. Hughes opted to go with, “I can’t dance; can you?” Keri responded by saying that she danced for 13 years, but she doesn’t dance anymore. Trevor prefers to dance as though no one were watching.  Repeating the sentiment of Men Without Hats, Shelby responded with, “you can dance if you want to,” before revealing that she danced for 12 years, but only because her parents wanted her to keep busy in high school.
Our Wonderful hosts intently listening to Hughes
(and definitely keeping track of points)
As Game 1 (a quick series of yes-or-no questions) began, the point system was introduced. Not unlike the TV show Whose Line is it Anyway?, these points would eventually be meaningless, but the competition aspect did add an interesting element to the games. In order to start strong, Alan decided to keep things simple, making sure the Hughes’s shirt was, in fact, blue. Trevor asked if he does steroids since he’s into baseball – to which Hughes sarcastically (?) said yes. Digging deeper, Shelby asked if, in his field, he would be able to make steroid, rendering another no. In the following series of questions, the audience learned that no costumes are involved in his work, he doesn’t have to touch gross things, and his research has nothing to do with sports or sports injuries. They also learned, that if unleashed upon society, his work wouldn’t be harmful to anyone despite it involving chemicals and combining physics and biology. Rather than hone in on correct answers, the panel seemed to be getting stumped. As this portion of the questions came to an end we learned that Hughes neither makes nor prescribes pills and the closest guess anyone had made pertained to making plastics and had something to do with gold. To help the panel get closer, the rules were changed, allowing for any questions to be asked (not just yes-or-no ones). It was during this portion that we learned that if his work were to become a product, doctors or police officers, etc would most likely use it and he makes microchips (but not the people-tracking kind). The audience also learned that he utilizes plastic and gold because the former is cheap and the latter is a good conductor that reflects infrared light very well.
After being asked if he intends to put gold inside people, Hughes gave the audience his three-minute-elevator-speech that efficiently outlines exactly what it is that he does when’s at work and not teaching. He’s making chips with channels roughly the size of a human hair, intended to carry very small amounts of fluids throughout them. Such a chip could be used for DNA sequencing, or moving biological samples around more easily. The gold is used to heat up the fluid; this is done by shining infrared light through one layer of gold and having it reflect off of the second layer of gold so it is trapped within the channels. As one of the panelists put it – he makes DNA ramen. With the panelists having gained a slight understanding of his work, a few more questions followed. Alan asked how much gold is used in each piece. Hughes explained that the amount of gold used is about a few thousand atoms thick, and a few million across; he is able to do this via a vacuum deposition process that requires him to suit up in what he referred to as a “bunny suit”. He explained further that one of the biggest challenges with this work was to get plastic and gold (two materials that don’t like to stick to things) to stick to each other. Completely by accident, a summer research student of his visiting from High Point University and then a JMU student working in his lab the following semester were able to use chloroform to make this happen.
Comedians from New & Improv.'d
As the first game came to a close, each of the hosts had a question for the expert. Tying the events together, Constantin mentioned that the last event had an astronomer (Shanil Virani) for an expert. She then asked if there were any questions Hughes would ask as a material scientist that an astronomer would never ask. Hughes replied that an astronomer would never ask, “How can I make this out of something else?” This is one of the core questions of material science – is there a better material out there and can the material of something be changed? Following up Constantin’s questions, Feitosa asked how Hughes became interested in material science and how it fits in with his hobbies. He said he simply really likes baseball and dance although they’re completely separate from his research. The enthusiasm for material science stemmed from working in his family’s machine shop growing up. He would be able to end the day having made something that hadn’t existed when the day began. Material science interested him because he was able to make things. He began his work as a material scientist doing work with microfabrication.
At this point, we moved on to the second game: Jargon & Acronyms. During this portion of the evening, the panelists were given a handful of phrases or acronyms Hughes encounters in his work with novel nanocomposite polymers and fabrication of microfluidic devices. It is then up to the panelists to figure out (or at least guess) what these phrases mean. Starting lightly, the audience learned that “nano” refers to an iPod Trevor used to have in addition to being the prefix that stands for 10-9. Hughes explains that many of the things he works with are nanometers in size. Next, the audience learned that a Reynolds number is used to describe fluid flow, with large values describing very turbulent flow. In his research, Hughes looks to work with fluids that have very low Reynolds numbers. They then learned that MOCVD stands for metal organic chemical vapor deposition and EOF means electro-osmotic flow. The latter is how fluid flows through the tiny channels mentioned above; by applying a voltage, the ions in the fluid are pulled, causing flow. This is necessary when dealing with fluids that have such low Reynolds numbers.
The last jargon/acronym questions dealt with Hughes’s hobbies instead of his research. First, the audience learned that the Froude number has nothing to do with pirouettes (despite dealing with dance) and isn’t 42, but rather a ratio involving the length of the leg and the force of gravity. Lastly, he explained what a Magnus force is. When you have a rotating projectile whose rotational axis is not parallel to the direction of motion (for instance, a baseball), the velocity of air with respect to the projectile is different for either side of the projectile. This difference in velocities surround the projectile causes its path to curve – like a curveball.
Overhead view of the panel and audience
In the last game, the panelists get to ask a series of random rapid-fire questions so the audience can get to know the expert better. It was during this portion that the audience learned that Hughes was born in Lexington, Kentucky and his favorite animal is the otter. His favorite ice cream flavor is chocolate and if he weren’t a physicist he would probably be a journalist. His favorite subject in school was history and clowns are definitely creepy (not funny). In order to work in his labs, students should be nanometer-sized and he has a profound love of Diet Coke (he actually smuggled one into the event). His college nickname was doc (or when his friends wanted to annoy him Chief Jackie) and his best friend is his wife.
Following the last game, we went to the audience for questions. One audience member asked how doctors, police officers, etc could use Hughes’s research. He explained that the idea behind the work is that it will help people process DNA more efficiently and on-site rather than sending it off to a lab and waiting. Lastly, he was asked what the best science joke to pull out at parties is. This question stumped Hughes because there are so many good ones. Constantin, however, was able to chime in with a classic: 2 atoms are hanging out. One has lost and electron and is very sad, lamenting, “I’ve lost an electron,” to which the other atom asks, “are you sure?!” and he replies, “I’m positive.”After the questions, the evening came to a close and the panelists spoke of all the wisdom they had gained throughout the evening such as, “Keep chloroform for those spontaneous moments.”

JMU students at the International American Vacuum Society (AVS) Symposium

On November 11th 2014, Harkirat Mann and Brian Lang presented at the AVS 61st International Symposium and Exhibition their research on "Infrared and thermoelectric power generation in thin ALD thermoelectric films" in collaboration with Janne Niemelä and M aarit Karppinen of Aalto University (Finland).  The section in which the students presented for was Atomic Layer Deposition (ALD) for emerging applications.  Before the presentation, the students got to hear a lot of great talks given by graduate students from all over the world, and see the startling size of the crowd...  After they finished presenting, they went to the main hall to see the exhibitions.  This was their favorite part of the trip, because of all sorts of amazing vacuum technology they could see, as well as get a massage! Brian commented; "This was a great experience to practice presenting in front of a large crowd, and a very educational experience hearing about the different technologies"

Sharon Koh - JMU Physics Alumnus of the Year

 
    On Friday, October 31 we were visited by the JMU Physics Alumnus of the Year, Sharon Koh. She spent the afternoon with faculty members, touring the department, and then she gave a seminar talk to the junior and senior physics majors discussing the work she’s done since graduating from JMU. After her talk, I was fortunate enough to sit with her for a few m
inutes and ask her a few questions to share with our readers. Below is a transcription of our conversation:



Can you start by giving us a brief outline from the time of your work at JMU until the present?

I got my Bachelor’s from JMU in 2002. I double majored in Chemistry and Physics and I double minored in Material Science and Mathematics. I went to Northwestern for grad school and finished that in 2007. My PhD was in Chemistry with a focus on materials chemistry; I worked with Tobin Marks and Mark Ratner. From there I went to Milliken and worked 6 years in industry, and now I’m at the Naval Research Laboratory as an ASEE postdoctoral fellow.

What would you say is your favorite project that you worked on?

That’s kind of a difficult question. Nobody’s asked me that before. When I was at Northwestern, probably the most interesting thing to me was the band structure stuff that I did just because nobody had ever done it before. So it was a good challenge that actually panned out. When we initially did it, we saw flat bands and we thought, “Okay, this isn’t interesting, we can’t publish this.” But then we were able to digress from there and, because we were creative enough and came up with different areas and reciprocal space to study, we actually were able to make the band structures turn into something that was useful and productive.
At Milliken, the carpet-printing project was probably the most interesting project because I was project manager, but I was involved in some of the science even though I wasn’t the engineer. I was doing manual work with the rest of the guys, putting those bars up in the plant when we went to commercialize, so we basically took it all the way from a prototype that was 1.5 inches all the way to 168 inches in a year and a half. They originally wanted us to do it in less than that; they’d given us 8 months originally. We could have done it, but there would have been a lot of flaws. We finally convinced them that we needed a little extra time. After we converted that broad loom machine I moved on to my other projects, but the rest of the engineers stayed on and ended up converting some tile machines over because they were so happy with the results, so it was a good success story. Also, because of that, we bought some equipment for the machine shop as well that they hadn’t had before, and because it was such a success on the broad loom, they ended up upgrading that machine to something bigger that could do more, which was a good capability for the company.

How long have you been at the Naval Research Laboratory and what have you been working on?

I’ve been there since December, so almost a year. I’m looking at decomposition of energetic materials; specifically we’re looking at nitromines and RDX materials. In the literature for the last 30-40-50 years, it’s been a known compound, but still, people don’t know how it works, because it’s so dangerous and the nature of how something like that detonates is so quick, it’s hard to have instrumentation to capture what’s going on. Experimentally is sometimes the best way to capture things, but if you can’t capture it experimentally, you have to develop models to better understand them. So that’s what we’re working on.

What was it like to go from carpets to explosives?


It was very different – it was interesting to read about them though. It is definitely interesting literature. Always when you start a new research project, what you end up doing is reading. Because you’re in a new area, you have to understand what’s already been done; you don’t want to start blindly, and so you end up reading a lot of papers, especially the first two weeks you’re on any new project. It was definitely interesting to see what other people had said about these energetic materials, and what’s even kind of scary is how all over the board the literature is about these materials. There’ve been so many studies out there, and almost everything gets published because nobody really knows what goes on, and that’s scary. I think now it’s starting to get to the point where people are starting to understand a little better and they’re starting to narrow down what gets published, so we’ll see what we can contribute to that.

Demystifying the Expert: The 1st Event in Images

   With the first event 3 weeks behind us and the second one only 2 weeks away,  it's time to start getting excited about the JMuse Café Demystifying the Expert series again! In case you've missed the previous post and the advertisements around campus, this series of events serves as a means by which to connect the scientific community of JMU with the general public in a unique and fun way through improv comedy. Each event consists of a panel of comedians from JMU's only improv group, New and Improv'd, and an expert whose expertise is unknown to both the panel and the audience at the beginning of the event. Throughout the evening the expert is demystified through games, discussions, and brief Q&A sessions. As we prepare for the event on November 6 with our expert  Chris Hughes, we've put together several pictures from the first event for those of you who weren't fortunate enough to attend:
