SURF Applications Open

Published
By

Cloud Chamber 201510230011Applications for 2017 Summer Undergraduate Research Fellowships are now open. Fellowship recipients will spend the summer on an individual research project under the guidance of a Michigan Tech faculty mentor. SURFs are open to all Tech undergraduates who have at least one semester remaining after the summer term. Awards are up to $4,000. Applications are due by 4 p.m. Jan. 27.

A workshop on writing effective SURF proposals is scheduled for 6 p.m. Monday, Dec. 5 in Fisher 132.

For more information, access to the application materials and instructions, visit the webpage or contact the SURF coordinator, Will Cantrell.

Teresa Wilson’s monthly series “This Month in Astronomical History” has released its November publication “Launch of Sputnik 2”. Each month, as part of this new series from the Historical Astronomy Division of the AAS, an important discovery or memorable event in the history of astronomy will be highlighted. This month, we look as the Soviet Union’s launch of Sputnik 2. You can read the compete article here or on aas.org.

Jaszczak Leads Discovery of New Mineral

Published

image144299-persA team led by a physicist from Michigan Tech has discovered a new mineral, named for the region in Tanzania where it comes from.

John Jaszczak knew that something was very unusual about the mineral specimen he was examining under the microscope of a Raman spectrometer in the basement of Fisher Hall.

On a hunch, Jaszczak decided to look into it further. The diagnostic studies with Raman spectrometry and scanning electron microscopy showed a layered structure rich in molybdenum, lead and sulfur that may be a new mineral. Now, Jaszczak and the team he pulled together can confirm that gut feeling. The tiny, silvery, cylindrical whiskers are indeed a new mineral—merelaniite. The journal Minerals published the team’s findings last week.

Detailed chemical and physical analyses of merelaniite—a member of the cylindrite group—revealed a neatly stacked layered structure with sheets rolled in scrolls like tobacco in a cigar. These tiny whiskers, which to the naked eye look like very fine hairs on other larger crystals, have probably been regularly cleaned off their host rocks containing other more recognizable minerals that occur at the famous gem mines near Merelani, Tanzania.

Screen Shot 2016-11-01 at 8.39.44 AM“Minerals have a natural wow factor, and while we use many of them daily without thinking twice, some specimens are truly art,” Jaszczak says, adding that minerals like the gems tanzanite (a blue/purple variety of zoisite) and tsavorite (a green variety of grossular garnet), which come from the same mines as merelaniite, can be more eye-catching. But it doesn’t negate the value of less showy minerals.

A Metacognitive Moment

Published
By

We’re beyond the halfway point in most classes, and it may be a good time to take just a (metacognitive) moment to review progress and map the road ahead.

In my physics class, I ask students each day as part of their class preparation to attempt an explanation of a real or simulated physics result. The question is based on material to which they’ve just had their first exposure, by reading or video lecture. It’s challenging, and initially not well liked. But it’s definitely something at which students improve with practice. They become not only more willing to “guess,” but they begin to support their answers with evidence, independent research and/or mathematical analysis far more often.

When I recently told my students that I had begun seeing that progress, a number of them spontaneously reflected and then shared agreement that this was getting more comfortable. It’s easy to lose track, in mid-semester, of how far you’ve come already. And it can be highly motivating to students when they see progress. In a similar way, looking backward momentarily can sometimes help put what remains in perspective.

As a physics student, when I first learned about rotational motion, I missed the idea that every rotational quantity had a linear analog. I struggled mightily as I tried to learn rotational kinematics in about a week, and the pace seemed completely unreasonable to me given that we’d spent about seven weeks learning the same concepts for linear motion.

This week, as I teach the same material, I explicitly connect each new rotational quantity back to the linear one. This seems to help students not only absorb the new material but reinforces the old and makes the pace more reasonable. A look backward could be an open-ended reflection on progress, or an explicit challenge to make comparisons to, connections with, or predictions about what’s coming. It could be done as a formal assignment, an in-class exercise, as a “minute paper” reflection near the end of a class or through a Canvas survey or quiz.

If you’re looking for other instructional strategies (and don’t want to wait for next week), stop into or contact the Jackson Center for Teaching and Learning.
