    The Substance of Soil

    Location: 

    Hunnewell Building, Arnold Arboretum, 125 Arborway, Boston

    Soil is the basis of survival. Without soil, humans and most other living beings could not exist. Conor Guidarelli, who has dug deep into the soils of the Arnold Arboretum will present an overview of soil, from its formation and components to its properties. He will discuss ways to analyze soil quality and health to determine whether or not amendments are needed based on the soil outcome or use desired.

    Participants are encouraged to bring a pint glass jar with about a cup of soil in it to class.

    Cost: $20 for members; $30 for nonmembers.

    Film Screening: Lobster War: The Fight Over the World's Richest Fishing Grounds

    Location: 

    Geological Lecture Hall, 24 Oxford St., Cambridge

    Lobster War is an award-winning documentary film about a conflict between the United States and Canada over waters that both countries have claimed since the end of the Revolutionary War. The disputed 277 square miles of sea known as the Gray Zone were traditionally fished by U.S. lobstermen. But as the Gulf of Maine has warmed faster than nearly any other body of water on the planet, the area’s previously modest lobster population has surged. As a result, Canadians have begun to assert their sovereignty, warring with the Americans to claim the bounty.

    Introduction to Bonsai

    Location: 

    Hunnewell Building, Arnold Arboretum, 125 Arborway, Jamaica Plain, MA 02130

    The Undiscovered

    Location: 

    Radcliffe Institute for Advanced Study, Knafel Center, 10 Garden Street, Cambridge, MA

    To paraphrase Louis Pasteur, sometimes luck favors the prepared mind, as when Alexander Fleming discovered penicillin by noticing that mold growing accidentally in his lab seemed to kill bacteria. This 2018 Radcliffe Institute science symposium will focus on how scientists explore realities they cannot anticipate. Speakers from across the disciplines of modern science will present personal experiences and discuss how to train scientists, educators, and funders to foster the expertise and open-mindedness needed to reveal undiscovered aspects of the world around us.

    Small Trees for Small Spaces

    Location: 

    Hunnewell Building and Landscape, Arnold Arboretum, 125 Arborway, Jamaica Plain, MA 02130

    Urban and suburban planting spaces are often constrained, often not ideal for accommodating a large oak, linden, or maple tree. But there are many smaller tree species that will thrive in a smaller space and won’t overwhelm the area. Some trees are cultivars that have been selected for their smaller size or narrow characteristics, while others are naturally genetically petite. Guided by the “right plant, right place” philosophy, Laura Mele...

    Quantum Tools to Explore the Universe…and Help Life on Earth

    Location: 

    60 Garden Street, Phillips Auditorium, 60 Garden St, Cambridge, MA 02138

    At the Center for Astrophysics, we exploit quantum physics to advance the state-of-the-art in measurement and imaging, and then apply these tools to search for Earth-like planets around other stars and probe the nature, history, and fate of the Universe. Sometimes, these quantum tools can also be applied to down-to-Earth problems — ranging from health to navigation.
