## Fermi Friday: Galactic Spaghetti

Often in discussions about blackholes, the question arises of observer experience when falling into a blackhole. Due to the extreme tidal forces experienced along such a path, the observer would be stretched out - a process colloquially referred to as...

## Fermi Friday: Baseball Blackhole

The question of interest this week is:

If all baseballs ever used in an MLB game were compressed into a blackhole, how large would the blackhole be?

To estimate the blackhole radius $$r_{BH}$$, we'll need...

## Found This Week #1

As this is the inaugural issue of the found-this-week series, I'll briefly note my motivation and inspiration. The title of this series is an overt nod to the famous series This Week's Finds written by...

## Fermi Friday: A Different Manhattan Project

For this week's installment of Fermi estimation, the question of interest is:

How fast would the sun burn an amount of hydrogen equivalent to the above-ground mass of Manhattan?

To estimate the burn-time we'll need to guess at a few...

## Blog Reboot

After completing the first year of graduate school (post on the industry $$\to$$ grad school transition forthcoming), I've finally got time to reboot the blog, with more focus. I'll be posting on a $$\sim$$weekly basis...

I first encountered a diagram of algebraic structures at the end of Jeevanjee's second chapter, "Vector Spaces", which elegantly summarizes the high-level differences in structure between sets, vector spaces, and inner product spaces.

## Loading Gravitational Wave Data with PyCBC

This post is the first in a series of in-depth examples for analyzing gravitational wave data in Python, using the PyCBC package. There is also a notebook-version of this post, available here, in a repo of PyCBC...

## Quick Python Setup

#### Motivation

Python has increased in popularity to near ubiquity in the past five years. While the Python community (correctly) professes simplicity as a major accomplishment of the language, I still get a lot of questions about how to get a python...

## Gravity of a Photon

A friend, who focuses primarily on experimental particle physics, recently asked me an interesting question about gravity. Specifically, he asked how the presence of electromagnetic fields impacts the gravitational field. Applying some modern-physics reasoning, he proposed...
