Built by a teacher who got tired of wasting students' time
I am P.S. Davis, a New Zealand-born author and physics teacher. I have been teaching for more than twenty years, and it never gets easier. Physics is already challenging enough without students having to wrestle with awkward formatting, clumsy equation editors, or the same constants copied out again and again.
That is why I started Pangram World. I wanted a place where students, teachers, writers, and generally curious humans could grab equations, calculate outcomes, manipulate symbols, and make useful text quickly. If you need a constant, you should be able to click once and paste it. If you want a clean equation for a document or a stunning PowerPoint, you should not have to fight the software first.
Even fiddly things like nuclide notation can be made in moments. Put in the numbers, copy the result, and move on with your life.
Why this site exists
Pangram World exists because too many useful things are still more annoying than they should be. Equation editors can be slow. Special characters can be buried under layers of menus. A simple bit of notation can take far longer than the thinking behind it.
I wanted tools that remove that friction. Less hunting. Less formatting. More getting on with the actual work.
What you can do on this site
Font and style generators
Add your own text and generate Unicode styles that work well in documents, social media posts, and email.
Symbols and icons
Mathematical, chemical, and decorative symbols are ready to click and paste. Handy for posts, messages, worksheets, and presentations.
LaTeX render tool
Produce crisp equation images with a little LaTeX know-how. You can also grab an equation from the physics pages and turn it into something ready for slides or documents in a couple of clicks.
Pangram generator
Generate pangrams of many different lengths. It is not limited to "the quick brown fox jumps over the lazy dog", and with a huge word pool the results can get gloriously unhinged. Be patient with it, though. It runs on JavaScript.
Roman numeral generator
Convert Roman numerals into standard numbers, or turn standard numbers into Roman numerals just as quickly.
Alphabets and letters
This section gives you quick access to a wide range of characters. It is not exhaustive, and not every section is technically an alphabet, but the labels are kept simple for clarity. Click a character and paste it where you need it.
Physics equations
Equations are drawn from the IB and other useful curricula, with some extra additions. They are available as clickable images, LaTeX, and plain text so they can slot neatly into documents, email, or social posts.
Calculators
The calculators work through the physics equations for any known variable, so you can test values, explore outcomes, and push things right up toward the speed of light without breaking out a separate app.
Click, copy, done
A lot of this site comes down to one idea: useful things should be easy to grab. Click once, paste once, carry on.
Free means free
I do all of this for free. You do not pay, you do not subscribe, and you are not being followed around the site by tracking cookies.
The aim is simple: make genuinely useful tools available without turning the place into a data-harvesting circus.
Why the book links are here
You will see book links throughout the site. I would love you to click them, share them, and read them. My hope is that one day writing becomes my full-time work in retirement.
Or before. I am not fussy.
Thanks for being here
Take your time, explore the tools, make your physics life easier, and if you fancy a trip into the world of Teloshka, the books are waiting.
