I like Angela Collier’s videos about physics and I was delighted to discover this 18-minute one…

…because it’s a great continuation to the thread about the complexity of Microsoft Office I shared recently.

Collier talks about why physicists prefer LaTeX to Word. LaTeX is sort of a nerdy HTML that predates HTML. It looks like this…

…and given how nerdy HTML already is, you might imagine this is a power-user tool that’s chiefly about power and control. But Collier makes the argument that there are some things that LaTeX makes much easier:

• there is absolutely no need (or peer pressure) to spend time styling the document by choosing fonts, colors, etc.,
• there is no “live preview,” and making a PDF is a separate step similar to compilation in coding – which means it doesn’t constantly occupy your mind,
• GUIs can slow you down because the keyboard is faster than the mouse,
• LaTeX doesn’t give you a lot of control over positioning, which is better than giving you only a semblance of control over positioning (this is the TikTok meme Collier alluded to briefly).

This is really interesting because it goes right to the core of the uncomfortable truth: naïve design decisions meant to make things easier might achieve the opposite. I shared the ForkLift example where the team didn’t understand what made the previous version great, and more recently the animation that could slow people down.

(Of course, there is also the issue of typographical craft of LaTeX documents set in Computer Modern, but let’s save this for another time.)

Also, the video starts with Collier apologizing for potentially making the audience feel dumb in a prior video. I don’t think it’s a joke, and I found it thoughtful and refreshing.
