The big Monday night science lectures at Centennial Hall aren’t the only accessible scholarship in Tucson.

You could fill every day and evening this week with food for thought — not to mention actual food, like pizza and beer.

From the genetic diversity of mountain lions to 100 years of anthropology to the science of love (on Valentine’s Day), University of Arizona researchers have important knowledge to impart — and it’s easily digestible.

Here are some tidbits from the smorgasbord of science, and links to even more upcoming events.

Today

Just in time for Tucson’s Gem, Mineral and Fossil Showcase, the Flandrau Science Center kicks off a special exhibit called “Meet the Trilobites — Arizona’s First Inhabitants.”

It features an array of the fossilized arthropods, which swam in the seas that covered the planet 250 million to 520 million years ago.

This is the only event listed here that involves a cover charge.

Monday

Before Brian Enquist’s talk on “Life in the Universe” (see related story), you can check out the exhibit of astronomical photography at the UA’s Center For Creative Photography, which is open until 5 p.m. on weekdays.

Astronomy and photography have been intimately linked from the beginnings of both. Photography made it possible to record and study astronomical phenomena; astronomy developed many photographic techniques and technologies.

The exhibit, “Astronomical: Photographs of Our Solar System and Beyond,” runs through May 17. Details at creativephotography.org

Tuesday

Take a hike, or a shuttle, halfway up Tumamoc Hill for a 6 p.m. talk by wildlife researcher Melanie Culver in Tumamoc’s historic library building.

In “Genetic Connectivity for Southwestern Puma Populations,” Culver will relate her recent research on the impact of the built environment on mountain lion populations.

The talk is free, but you’ll need to make a reservation. Email cynthiaanson@email.arizona.edu or call 629-9455.

Wednesday

You may have to make a choice: beer and Martian craters or a full bar and augmented reality.

The UA’s Confluencenter for Creative Inquiry brings the augmented-reality experience to the Playground Bar & Lounge, 278 E. Congress St., from 6 p.m. to 7:30 p.m.

You can “walk” the streets of Paris with a study-abroad class, “When African-Americans Came To Paris and Berlin,” taught by Bryan Carter, assistant professor of Africana studies.

The presentation “Walking the Spirit: Augmenting the Paris Experience,” will show the film the students produced and explain how it was created with specialized software and mobile devices.

Over at Borderlands Brewing, 119 E. Toole Ave., researchers with the UA Lunar and Planetary Lab’s HiRISE camera team will bring cool pictures of Martian craters along with pizza to go with the beer.

The 30-minute talk by Ali Bramson and Donna Viola is titled “Crazy Craters: Windows into Martian Ice.” It starts at 7:30 p.m., so you could make both events if you really tried. More info on the “Space Drafts” series: www.lpl.arizona.edu

Thursday

At 6 p.m., the UA’s Institute for the Environment presents “Can Money Grow on Trees: Exploring Guatemala’s Forestry Incentive Programs” at Borderlands Brewing, 119 E. Toole Ave.

Graduate student Niki vonHedemann, one of the institute’s Carson Scholars, will talk about how financial incentives are used as conservation tools.

The UA’s Special Collections Library opens “Celebrating Excellence: 100 Years of UA Anthropology” on Monday and will hold an opening reception and talk Thursday.

The exhibit includes historical documents, photos, articles and books about the school and its famous archaeologists and anthropologists.

The reception — from 6 p.m. to 7:30 p.m. — includes a talk by Diane Austin, director of the school, titled “University of Arizona Anthropology: A Century of Continuity amid Change.”

Saturday

Celebrate Valentine’s Day with music and psychology, because, really, what’s more romantic than deconstructing the emotion of love?

One of a series of monthly Creative Collaborations put on by pianist Paula Fan at the UA’s main book store, it blends music with scholarly research.

This time, psychology researcher David Sbarra will speak on “the science and psychology behind Cupid’s arrow,” and Fan will play “love” songs.

It’s at 11 a.m. to noon at the book store, 1209 E. University Blvd.
