Author of Think Bayes & Think Python

Bio: I am a Professor of Computer Science at Olin College in Needham MA, and the author of Think Python, Think Bayes, Think Stats and several other books related to computer science and data science. Previously I taught at Wellesley College and Colby College, and in 2009 I was a Visiting Scientist at Google, Inc. I have a Ph.D. from U.C. Berkeley and B.S. and M.S. degrees from MIT. Here is my CV. I write a blog about Bayesian statistics and related topics called Probably Overthinking It. Several of my books are published by O’Reilly Media and all are available under free licenses from Green Tea Press.

Generational changes in support for gun laws

Generational changes in support for gun laws

This is the fourth article in a series about changes in support for gun control laws over the last 50 years. In the first article I looked at data from the General Social Survey and found that young adults are less likely than previous generations to support gun control. In the second article I looked at data from the […]

Support for gun control is decreasing in all age groups

Support for gun control is decreasing in all age groups

This is the third article in a series about changes in support for gun control over the last 50 years. In the first article I looked at data from the General Social Survey and found that young adults are less likely than previous generations to support gun control. In the second article I looked at data from the CIRP […]

Post-Columbine students do not support gun control

Post-Columbine students do not support gun control

In their coverage of the Parkland school shooting, The Economist writes: Though polling suggests that young people are only slightly more in favour of gun-control measures than their elders, those surveys focus on those aged 18 and above. There may be a pre- and post-Columbine divide within that group. Based on my analysis of data from the […]

Support for gun control is lower among young adults

Support for gun control is lower among young adults

In current discussions of gun policies, many advocates of gun control talk as if time is on their side; that is, they assume that young people are more likely than old people to support gun control. This letter to the editor of the Economist summarizes the argument: It is unlikely that a generation raised on lockdown drills, […]

The Six Stages of Computational Science

The Six Stages of Computational Science

This is the second in a series of articles related to computational science and education.  The first article is here. The Six Stages of Computational Science When I was in grad school, I collaborated with a research group working on computational fluid dynamics.  They had accumulated a large, complex code base, and it was starting to […]

The retreat from religion is accelerating

The retreat from religion is accelerating

This is an extended version of my article in the Scientific American blog. The data I used and all of my code are available in this Jupyter notebook. Secularization in the Unites States For more than a century religion in the the United States has defied gravity.  According to the Theory of Secularization, as societies become more modern, […]

Last batch of notebooks for Think Stats

Last batch of notebooks for Think Stats

Getting ready to teach Data Science in the spring, I am going back through Think Stats and updating the Jupyter notebooks.  Each chapter has a notebook that shows the examples from the book along with some small exercises, with more substantial exercises at the end. If you are reading the book, you can get the notebooks by cloning this […]

Another batch of Think Stats notebooks

Another batch of Think Stats notebooks

Getting ready to teach Data Science in the spring, I am going back through Think Stats and updating the Jupyter notebooks.  When I am done, each chapter will have a notebook that shows the examples from the book along with some small exercises, with more substantial exercises at the end. If you are reading the […]

Third batch of notebooks for Think Stats

Third batch of notebooks for Think Stats

As I mentioned in the previous post and the one before that, I am getting ready to teach Data Science in the spring, so I am going back through Think Stats and updating the Jupyter notebooks.  I am done with Chapters 1 through 9 now. If you are reading the book, you can get the notebooks by cloning this repository on […]
