Third Laptop: Lenovo ThinkPad P14s

My previous laptop was an ASUS UX331UN, and I wrote a post when I got it 6 years ago reviewing it [LINK]. It served me well, so I figured for a while that when it came time to replace it, I would most likely get another ASUS laptop. (Read more...)

Some Dangers of Confusing “Changing One’s Mind” with “Bayesian Updating”

Recent conversations with friends & colleagues about probability theory reminded me of conversations with a friend of mine in graduate school about the supposed virtues of making one's own reasoning in one's daily life more systematic through Bayesian inference. The basic idea, in rough qualitative terms, is that one's belief (Read more...)

Disability, History, Wilderness, Natural Parks, and Urban Spaces (Part 2)

This post is a follow-up to a post [LINK] about an essay by the environmental history professor William Cronon, which in turn was about the ultimately delusional, dishonest, or hypocritical (the particular adjective depending on one's viewpoint) way that many Americans & Europeans since the 19th century have (Read more...)

Disability, History, Wilderness, Natural Parks, and Urban Spaces (Part 1)

Over the 3 years that I physically lived in California (as I worked remotely for UC Davis remotely from Maryland for 1 year before that), I became progressively more ambivalent about the reverential attitudes that many people in California and more broadly in the western half of the contiguous US (Read more...)

Reflection: Leaving UC Davis

This week is my last week as a postdoctoral researcher at the UC Davis Institute of Transportation Studies (ITS-Davis). I am glad that I was able to transition from physics to transportation policy within the setting of academia and to particularly to so at ITS-Davis, which is renowned for having (Read more...)

Finite Determinants of Linear Operators in Continuous Vector Spaces

Recently, I wondered whether it is possible for a linear operator in a continuous (infinite-dimensional) vector space to have a finite determinant. By "continuous vector space", I mean that the identity operator can be resolved for a complete orthonormal basis \( |\phi(x) \rangle \) for all \( x \) such (Read more...)

Transitioning from microscopic to macroscopic and quantum to classical regimes

I recently read two things that were of interest to me having previously worked in physics. One was an article in The New Yorker magazine [LINK], in which the author does a good job of going over the successes of mathematical modeling in the physical sciences and contrasting (Read more...)
