Listen to Quanta Magazine
Turn any quantamagazine.org article into audio. Open the piece in Chrome, click CastReader, and listen from the dek through the last paragraph — with paragraph highlighting. Quanta is 100% free, so every article is fully listenable.
Why Listen to Quanta with CastReader?
Quanta publishes the clearest explanations of modern mathematics and physics anywhere. Audio + highlighting makes them followable.
Full Article
Dek, Byline, Body
CastReader reads the dek (Quanta's italic intro), the byline, and the full article body in order. Section subheads are read as brief orienting landmarks. Your audio starts with 'By [Author]' and ends at the last paragraph.
No Paywall
Every Quanta Article Is Free
Quanta is funded by the Simons Foundation and runs no paywall. Every article has full text in the DOM. CastReader reads all of it — from any article, start to end, no 'subscribe to continue' ever cuts the audio short.
Clean Audio
Skips Newsletter and 'Related' Rails
Quanta's sidebar has a newsletter signup and a 'related articles' strip. CastReader reads only the article body and stops at the last paragraph — not at the newsletter sell.
100% Free
Math and Physics for Commutes
No signup, no quota. A Quanta feature is 20–35 minutes at 1.5x — perfect for a commute or a walk. Paragraph highlighting means when a definition arrives you can see it, which matters for math.
Frequently Asked Questions
Everything about listening to Quanta Magazine with CastReader
How do I listen to a Quanta article?
Open the piece on quantamagazine.org in Chrome (URLs look like /the-article-title-20260424/). Click the CastReader icon. It reads dek, byline, and full body.
Is Quanta really fully free?
Yes. Quanta is a nonprofit publication of the Simons Foundation. Every article is free to read in full — and every article is fully listenable with CastReader. No paywall, no metered access.
Does it handle mathematical notation?
Quanta is unusually good at writing math without equations — the articles use prose to convey what's mathematically happening. CastReader reads the prose. When the page does contain inline math (rare on Quanta compared to a journal), it reads the math as it appears in the HTML, which may be imperfect for complex LaTeX.
What about figures and animations?
Figures and animated visualizations are skipped because audio can't represent them. Quanta often opens an article with an illustrated scene — you'll hear the article text, and when a specific illustration matters to the argument, the surrounding paragraphs describe it explicitly.
Does it work on the Quanta podcast (The Joy of Why)?
The Joy of Why is audio already — podcast apps handle that. CastReader is for reading Quanta's written articles. Each Joy of Why episode page does include a written introduction; CastReader reads that.
What gets skipped?
Newsletter signup prompts, 'More from Quanta' rails, Simons Foundation logos and footer chrome. Only the article itself reads.
Can I adjust reading speed?
Yes. 0.5x through 3x. Math articles often want 1.3x–1.5x — slow enough to let definitions land, fast enough to move.
Is it free? Any limits?
Completely free with no page or character limits. No account needed. CastReader is a free browser extension for Chrome and Edge.
