How to Follow or Subscribe to Updates on Terence Tao's "What's new" Blog

The most reliable way to keep up with Terence Tao's "What's new" blog is to subscribe to its feed, which the site lists directly in its navigation. If you prefer not to use a feed reader, you can also check the homepage, where posts appear in reverse-chronological order, or follow Tao on Mastodon, which is linked from the site's menu. The blog is a personal research and exposition site rather than a newsletter service, so there is no indication of an email subscription or paid tier — the feed is the primary built-in mechanism for staying current.

Subscribe via the site's feed

The blog's navigation includes a "Subscribe to feed" link, which is the intended way to receive new posts automatically.

1. Open the blog's homepage.
2. Locate the "Subscribe to feed" link in the top navigation menu.
3. Add that feed URL to your feed reader (for example, Feedly, Inoreader, NetNewsWire, or a self-hosted reader).
4. Your reader will then surface new posts as they are published, without you needing to revisit the site.

Expected result: new entries appear in your reader shortly after Tao publishes them. Common snag: if the feed URL doesn't load in your reader, try pasting it into a browser first to confirm it returns feed content rather than an error page.

Follow by browsing the homepage

If you'd rather not use a feed reader, the homepage itself works as a manual update check. Posts are listed newest-first, each with a date, category, and tags.

• Date tells you how recent a post is (for example, "4 October, 2026").
• Category and tags (such as expository, math.AP, Euler equations) let you judge relevance before reading.
• Author line distinguishes Tao's own posts from guest posts, which are labeled as such.

This is the simplest option if you only want to check in occasionally, but it requires you to remember to visit.

Follow via Mastodon

The site's menu links to Tao's Mastodon presence alongside "Home," "About," "Career advice," "On writing," and "Books." Following there can surface announcements and discussion in a social feed rather than a chronological blog list. This is a complement to the feed, not a replacement — not every blog post is guaranteed to be mirrored there.

Engage through comments

Comments are enabled on posts, so if your goal is not just to read but to discuss, you can follow a specific thread after reading. Note that individual posts may have comment activity that is more current than the post itself, which matters for fast-moving topics like the recent Euler and Navier–Stokes discussions.

Choosing between the options

If your priority is completeness, use the feed. If your priority is low friction, bookmark the homepage and check the date on the top post. If you want discussion, combine the feed with comment threads on the posts you care about.

What you'll be following

Knowing the blog's scope helps you decide how closely to track it. Recent homepage entries include expository and research posts such as "On classical solutions and singularity formation in incompressible fluids" (tagged expository, math.AP), course notes like "247A, Notes 2: The Hardy–Littlewood maximal function and applications," opinion and guest posts such as "What does the advent of powerful AI models mean for mathematicians like me?", and site news like "arXiv updates its rate limiting policy." The mix means updates arrive at irregular intervals and span research, teaching, and commentary — so a feed reader that lets you filter by tag is more useful than one that only shows a flat list.
