Nantucket Maria Mitchell Association Welcomes Tanveer Karim Featured Guest for July Science Speaker Series

June 26, 2023

NANTUCKET, MA—The Nantucket Maria Mitchell Association (MMA) announces that it will host Tanveer Karim as a featured presenter for its Science Speaker Series. His presentation, “Measuring the Growth of the Universe with Multiple Datasets,” will take place on July 5 at 7pm. It will be presented in-person at the MMA Research Center at 2 Vestal Street and via Zoom. This event is free to all.


How the largest structures in the Universe grew from the beginning of time to what we see today is a major puzzle in understanding the evolution of our Universe. Recent studies that measure the growth of structure in our Universe appear to disagree with each other depending on whether the data was obtained from the very early Universe or the more recent Universe. In this talk, Tanveer Karim will contextualize this emerging and exciting, yet puzzling, anomaly seen in cosmological datasets and what it may suggest about our Universe. Additionally, Karim will share a new measurement that hopes to shed light into this anomaly using multiple datasets. Finally, he will expand on how the ongoing and future cosmological surveys can potentially resolve this anomaly and paint a comprehensive picture of the evolution of the Universe.


A 2016 Maria Mitchell Association (MMA) National Science Foundation Research Experience for Undergraduates intern in the MMA Astronomy Department, Tanveer Karim is currently a visiting postdoctoral fellow at the Center for Astrophysics | Harvard & Smithsonian and will be starting as a Faculty of Arts & Sciences Fellow and a Dunlap Fellow at the University of Toronto in the fall of 2023. He recently defended his Ph.D. from Harvard University and prior to that obtained his B.S. in Physics and Astronomy from the University of Rochester. His area of specialization is Observational Cosmology, and he has been involved with the Dark Energy Spectroscopic Instrument (DESI) collaboration since the beginning of his graduate school career. Outside of research, he enjoys the outdoors, reading, and learning languages.


The Maria Mitchell Association was founded in 1902 to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. After she discovered a comet in 1847, Mitchell’s international fame led to many achievements and awards, including an appointment as the first female professor of astronomy at Vassar College. Maria Mitchell believed in “learning by doing” and today that philosophy is reflected in the MMA’s mission statement, programs, research projects, and other activities. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages.

I have posted this during Women’s History Month before but because it is March and again Women’s History Month, I think it’s worth repeating. It’s clever and helps to tell an important story in women’s history while giving it a bit of a 21 st century twist. It comes via the National Women’s History Project. JNLF

NANTUCKET, MA—The Maria Mitchell Association (MMA) invites the community to take part in an important conversation on owl preservation. The MMA will host a free virtual panel bringing together specialists in wildlife conservation to discuss the challenges these remarkable birds face today on Nantucket and beyond. This free presentation will take place Wednesday, March 18 from 6 – 7pm on Zoom. Owls are an essential part of Nantucket’s delicate island ecosystem. As natural predators, they help keep rodent populations in balance and serve as important indicators of environmental health. In recent years, however, growing threats—including the spread of Avian Influenza and the widespread use of rodenticides— have raised serious concerns for local owl populations and the broader bird community. This timely discussion will explore how these issues are affecting owls across the region and what they may mean for Nantucket’s wildlife and landscape. Panelists will share current research, discuss conservation efforts, and offer practical ways the community can help protect these iconic nocturnal hunters. By bringing together scientists, conservationists, and community members, the event aims to foster awareness and collaboration around protecting Nantucket’s natural heritage. Residents, nature enthusiasts, and anyone interested in the island’s wildlife are encouraged to join the conversation. The discussion will feature acclaimed naturalist and author, Scott Weidensaul, a Pulitzer Prize finalist for his book, Living on the Wind. He is also the author of A World on the Wing. A contributing editor to National Audubon and a longtime columnist for Bird Watcher's Digest, Weidensaul is a Fellow of the American Ornithological Society and co-founder of Project SNOWstorm, which tracks snowy owl movements through satellite telemetry. Joining Weidensaul will be Susan Baker of the Chicago Ornithological Society and the Chicago Bird Alliance Rodenticide Committee; Meaghan Q. Sinclair, a Mass Audubon Certified Field Naturalist, wildlife photographer, co-founder of Save Concord Wildlife, and member of the Mass Audubon Governance Council; Heather Packard, Community Organizer with Mass Audubon’s Policy & Advocacy team and manager of Climate and Nature Champions; Gwen Shipley, a Council Co-Leader and Climate and Nature Champion with Mass Audubon; and Ginger Andrews, the MMA’s Field Ornithologist. Together, these distinguished experts bring deep scientific expertise, conservation leadership, and extensive field experience to a timely and engaging discussion. This event will be held via Zoom. Pre-registration is required.

It’s sort of funny what Mother Nature does. Granted, in this case, she had a little help by shovel or plow. But as I made my way up Vestal Street a week ago or so, after the first round of eight inches of snow or so, I noticed this ice shape on the front stoop of the Mitchell House. To me, it looks like a whale with its tail up in the air! I think it’s sort of appropriate for this front stoop so I decided to share! JNLF
