Hello, World

This is a first post on a freshly rebuilt site. It exists mostly to test the typographic features of Tufte CSS, and partly because starting a blog without a first post feels like hanging an empty picture frame.

Sidenotes and margin notes #

The beauty of Tufte’s layout is its generous margins.(1) (1)Sidenotes like this one are numbered and appear in the margin. On mobile, they collapse to inline toggles. Margin notes work similarly but without numbers.⊕ This is a margin note — no number, just a quiet aside.

The idea is simple: supporting information belongs in the periphery, not in the body text. Footnotes force the reader to bounce to the bottom of the page; sidenotes keep everything in view.

Figures #

The Tufte layout supports figures in the margin and at full width. Here is a regular figure:

⊕ Cumulative heading direction of a larval zebrafish over 10 seconds of free swimming. The monotonic increase suggests a slow, persistent turn.

Code #

Here is a block of Python, since that is what I write most:

import numpy as np

def heading_direction(velocities):
    """Integrate heading from angular velocities."""
    return np.cumsum(velocities) % (2 * np.pi)

What to expect #

I plan to write about data science, neuroscience, Python tooling, and the occasional stray thought. No schedule, no promises. Just writing when something feels worth sharing.
