Why do so many powers of 2 start with “1”?

1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384 …

If you liked math in middle school, odds are that maybe you memorized the powers of two. But did you ever think about the fact that so many of them start with the digit “1”? Is there a reason for it? How would you go about stating the problem in more formal mathematical terms?

Dmitry Kleinbock from the Brandeis Math department explains in this Numberphile video:

Be sure to watch the extra content (below) for a slightly more technical, but still completely approachable, additional explanation, where the problem reduces to the so-called equidistribution property of irrational rotations of the unit circle.

Are there other numbers more likely to start with the digit “1”?  It’s pretty easy to convince yourself that there are.

IGERT Summer Institute – July 27 to August 7, 2015

IGERTBrandeis is hosting a two-week summer institute for graduate students in the mathematical sciences from July 27-August 7.  This will combine the annual summer institute of Brandeis’ Geometry and Dynamics IGERT program, with a sequel to the US-India Advanced Studies Institute on thermalization, held two years ago in Bangalore.


  • Large deviation theory
  • Statistics of extreme events
  • The large N expansion in statistical and quantum physics
  • Statistical fluid dynamics
  • Quantum information and quantum gravity
  • Thermalization in Quantum Systems

3 Division of Science Undergrads Win 2015 Giumette Academic Achievement Awards

lab_imageThree of five Guimette Academic Achievement Awards were recently given to Division of Science sophomores, according to Meredith Monaghan, Academic Services.  Each award is worth $5000 per semester for the remaining four terms of study.  In order to qualify for consideration, applicants must be sophomores with at least a 3.50 GPA who are not already receiving other merit awards. All 2015 recipients have been named to the Dean’s list in every semester.

The Giumette Academic Achievement Award began in the 2004-05 academic year to recognize currently enrolled sophomores who have distinguished themselves by their outstanding scholarship and academic achievements at Brandeis. The Academic Achievement Awards have been re-named after Peter Giumette, in honor of his twenty years of service to Brandeis as the head of Student Financial Services.

The Division of Science Giumette recipients are:

Zoe Brown ’17 is double majoring in Neuroscience and Psychology and has worked as a research assistant in Professor Arthur Wingfield’s Memory and Cognition Lab. This experience led Zoe to an internship at McLean hospital, where she works in the Bipolar and Schizophrenia division. Zoe will be a Bauer Foundation Summer Undergraduate Research Fellow in the Wingfield lab this summer. After graduating from Brandeis, Zoe plans to enter a Ph.D. program in either neuroscience or psychology and hopes to work in clinical neuropsychology, research, or teaching.

Kahlil Oppenheimer ’17 is double majoring in Computer Science and Mathematics. He serves as both a Teaching Assistant and an Undergraduate Department Representative for the Computer Science department. He has worked as an intern for both Draper Laboratories and HP Vertica, where he has utilized his academic knowledge in a real-world setting. Kahlil will be a software engineering intern at Kayak this summer and hopes to continue to explore both applied and abstract mathematics.

Leah Shapiro ’17 is majoring in both Biological Physics and Mathematics. Leah has been conducting independent research with Professors Jané Kondev (Physics) and Jeff Gelles (Biochemistry), on an interdisciplinary project investigating gene regulation and expression.  This summer Leah will be participating in research at the Yang Laboratory at the University of Michigan.

John Wardle Named Division of Science Head

John Wardle, Division of ScienceSusan Birren, Dean of Arts and Sciences, has announced that John Wardle, Professor of Physics, will be the new Head of the Division of Science.

The following is Susan’s email:

“I am pleased to announce that John Wardle will be the new Head of the Division of Science.  John is an astrophysicist and Professor of Physics and is a former chair of the Physics department.  In his new role he will oversee science-wide programs and initiatives, including the summer undergraduate research program and will work with Division of Science faculty and staff to identify new directions for the division.  I am delighted that he has agreed to take on this role and I hope that you will join with me in welcoming him.

We all owe a debt of gratitude to Eve Marder who, as the first Head of the Division, created and steered many of the priorities of the Division.  During her time as Head, Eve ably represented the Sciences at Brandeis and beyond, worked to make the Summer Undergraduate Science Program a flourishing success, changed the way we trained students and postdocs in the ethical conduct of research, and worked tirelessly to secure funding and recognition for the Sciences.  Thank you Eve!”
