How to Read STEM and Math-Heavy Papers on Screen
Figures, tables and equations are what make STEM papers hard on screen. Read them in layers and hear notation spoken correctly.
STEM papers are hard to read on a screen for three reasons that have nothing to do with the science: the layout (two columns, tiny type), the visuals (figures and tables far from the text that explains them), and the notation (equations, units and symbols that stop you mid-sentence). Fix those three and the content becomes much easier to follow. This guide covers how to do that, and how to use a reader that was built to handle all three.
What Makes STEM Papers So Hard on Screen
The layout is built for print. Two narrow columns, 9 point type and footnotes in the middle of your line of sight. On a laptop you scroll up and down inside one page, and your place disappears every time you look at a figure.
The visuals are separated from the argument. Figure 3 is on page 6, and the paragraph that explains it is on page 4. You flip back and forth and lose the thread.
The notation interrupts reading. A sentence like "R² = 0.98 ± 0.02 for n = 12 (p < 0.05)" is quick for an expert and a brick wall if you are new to the field. Reading it aloud in your head is how many people parse it, and that is where most text-to-speech falls apart.
Citations clutter the prose. Bracketed references and superscript markers sit in the middle of sentences, so the grammar is hard to hear.
Step 1: Get the Paper Into a Format You Can Control
The first step is to stop reading the PDF as a picture of a printed page. In Nook, you import the PDF (or EPUB) and it becomes clean reflowable text with the figures, tables and equations in place. Scanned papers go through OCR on import, so old journal scans become real text too.
Once it is in, you control the font, spacing, size and background. A calm cream or dark page and a readable font like Lexend or Atkinson Hyperlegible Next reduce the visual load of dense text so your attention goes to the content. Try a few backgrounds on this page:
Step 2: Read the Visuals First
Before the body, look at every figure and table with its caption. In a STEM paper the figures often carry the whole argument. Ask what each axis is, what is being compared, and what the main trend is. Then read the paragraph that discusses it.
In Nook, figures keep their captions and tables stay tables, so you are not trying to parse a table from a block of text. Highlight the result you think is the main one and attach a note, so it is easy to find again when you write about it.
Step 3: Work Through the Equations in Layers
You do not need to check every derivation on the first read.
1. First pass: note which symbols the paper uses and what they stand for. Skip the algebra.
2. Second pass: follow the logic of each equation, asking what it says in words.
3. Third pass: verify the steps that matter for your purpose.
Use Explain on anything that does not make sense. Select the passage and ask for an explanation instead of opening a search tab. Select a single word to get its definition. You stay in the paper and keep your place.
Keep a note on each symbol that confuses you. By the end you have a short glossary attached to the paper.
Step 4: Listen to the Parts You Keep Rereading
Reading aloud is a good way to parse a dense sentence, and hearing it spoken correctly makes a real difference. Nook's Listen was built to speak scientific text the way a person would:
| On the page | Spoken |
|---|---|
| R² = 0.98 ± 0.02 for n = 12 | "R squared equals 0.98 plus or minus 0.02 for n equals 12" |
| p < 0.05 | "p less than 0.05" |
| y = mx + c | "y equals m x plus c" |
| 120 °C, 5 wt% | "120 degrees Celsius", "5 weight percent" |
| Fig. 2 | "Figure 2" |
| TGA, SEM, FTIR | "T G A", "S E M", "F T I R" |
| Bracketed citations, footnote marks | Skipped |
Greek letters, operators, units and chemistry notation are handled in context, so the same superscript is spoken one way when it is a power and another way when it is a charge. Tables are read with the headers once, then each row. Words highlight as they are spoken, so you can follow along with your eyes.
It does not replace looking at a figure or working through a displayed derivation, since audio cannot describe a chart. It stops the notation from derailing the sentence around it. For the full explanation, see text to speech that reads equations and technical terms.
Press play to hear a sentence with an equation, a p-value, an abbreviation, a figure reference and a citation marker:
Step 5: Stay in the Paper for 25 Minutes at a Time
STEM papers punish divided attention. If you open a tab to look up one thing, you lose the thread of the derivation.
Nook has a Pomodoro timer built in. Set a read length and a break length, and a clock sits on the toolbar. Add YouTube, X or anything else that usually wins to the block list, and those sites stay blocked during the read phase and return when the break starts. The block list needs the Nook extension. See our guide to using a Pomodoro timer for reading and studying.
Here is what a blocked site looks like during the read phase:
Step 6: Keep What You Learned
At the end, write three sentences: what was the question, what was the result, what does it change for you. Check them against the Summaries panel, which lists the takeaways and lets you jump to the passage each one came from. Put the paper in a folder for the project it belongs to, and bookmark the passages you will need to cite.
Try it on a paper you need to read this week. The trial is 3 days with everything included, then $5/month or $39/year.
What to Expect, and What Not To
STEM papers with figures, tables and equations are a strength of the reader. A few honest limits:
- Audio will not describe a figure. Pause Listen, look at the figure, then resume.
- Heavily designed textbooks are different. Pages with callout boxes, sidebars and text in shaded panels lose those boxes in OCR. Papers, theses, reading packs and plain textbooks are fine. See can you study from a PDF textbook.
- Nook is not a citation manager. Use Zotero for bibliographies.
Frequently Asked Questions
Can Nook handle papers with equations and figures?
Yes. Papers with figures, tables and equations are a strength. Import the PDF and the figures, tables and equations stay in place. Scans go through OCR on import.
Does text to speech read equations correctly?
Inline notation, yes. Listen speaks symbols like R², ±, p < 0.05, Greek letters, units such as degrees Celsius, and chemistry notation as words, and skips citation markers. A displayed derivation or a figure still needs your eyes.
How do I read a math-heavy paper without getting lost?
Read in layers: abstract and conclusion first, then figures and tables, then the body. On the first pass note the symbols and skip the algebra, follow the logic on the second, and verify the steps that matter on the third.
What if I do not understand a passage?
Select it and use Explain to get an explanation, or select a single word for its definition. If the paper is simply too far from what you know, find a review article first.
Can I read STEM papers on my phone?
Nook is a web app that works on any device, so papers you import are available on your phone or tablet too.
