Custom Better Posters bookplates

Bookplate saying "Ex libris", "With the gratitude of the author" and "Pelagic publishing".

Here’s one for the book nerds.

For people who ordered the physical copies of the Better Posters book, I have a little something for you. I have just ordered some custom bookplates for you!

Some of my friends told me they want signed copies of the book. I personally am not all that interested in packing up books and hauling them to the post office or where. But sticking bookplates in an envelope? That I can do!

These will probably arrive slightly after the book does. (Grading my classes kept me from being slightly more prompt about this. Sorry.)

If you want one, show “proof of life” (that is, a picture of your copy of the book) on social media (Twitter, Instagram, Facebook, or wherever). Email me the link at BetterPosters@gmail.com and include your mailing address. Pics of the book next to pets, in cool places, or by smiling faces are appreciated but not required.

While I freely admit that this is a bit of a marketing gimmick, the bigger thing I hope to get out of this is to see the book out in the world and in the hands of people who I hope will find it useful and enjoyable.

Never use a graph you can’t explain

 

Box plot on left, violin plot on right showing same data.
 

Irena Chelyseva asked if people preferred box plots or violin plots. She said, “I guess there is no right answer.”

I think there is, if not a right answer, a justifiable answer for why some people should use one or the other.

I can explain absolutely every element in my box plots. Usually, center line in the median, box is 50% of the data, whiskers are 95% of the data, and I have symbols for minimum and maximum. 

There is no accepted standard for box plot displays, however, particularly for the whiskers. People often fail to label the graph enough for me to interpret them.

So I frequently have to ask people, “What are the whiskers in your box plot showing?” (Or bar graph, but people are usually a bit better at labeling them.) And I am surprised by how often they can’t tell me. They’ve forgotten.

I recently asked, and the presenter said, “I think they’re quartiles.” But quartiles should include the entire range of data, and their plot had data points past the end of the whiskers.

This makes for an uncomfortable moment when you’re presenting a poster.

Getting back to the original question, this is why there is at least one good justification for preferring one chart over the other. 

I can’t explain what a violin plot shows. I know in principle that the curve shows and estimate of distribution. But I can’t tell you how the curve in a violin plot is calculated or derived. Because it’s an estimate, I suspect there are different methods of estimating distribution, and I don’t know how they differ.

I should use box plots instead of violin plots, regardless of the data, because I know how to explain what one shows but not the other.

It doesn’t matter if one graph shows something better in theory if I can’t communicate exactly what is being shown.

As goes Microsoft, so goes academia. At least in regard to design. 

For years, we’ve looked at a lot of posters and slide talks that looked kind of similar because they all used Calibri, because it is Microsoft’s default font in Office.

Calibri’s days as default are numbered. Microsoft has announced it will be retiring Calibri as their default Office font. Click to enlarge to see the candidates to replace it.

Chart comparing Calibri with teh five candidates to replace it: Skeena, Grandview, Bierstadt, Tenorite, and Seaford.

Skeena looks closest to Calibri. 

Bierstadt looks like a Helvetica imitator (and the name doesn’t exactly roll off the tongue). 

Grandview looks tiring for extended blocks of text because of its angles and high x-height. 

Tenorite’s geometry appeals to me in the way Futura does.

Seaford is my current favourite.

Variable fonts: A quick introduction

Variable fonts are here
 

Recently, I talked about type as a form of technology. I was more interested in the idea of the shapes of the letters and numbers and the amount of special symbols, so overlooked something kind of obvious. 

Fonts are technology, too. And more obviously so.

(Aside: Typefaces are styles and shapes of letters. The fonts are the way those style get implemented. Type is like a song, font is like the recording of a song.)

One of the biggest additions to type technology is the addition of variable fonts.

The issue that variable fonts can solve is that because of various optical effects, you can’t make a thin letter into a thick letter just by thickening the lines. Well, I suppose you can but it doesn’t look right. And two letters that should be the same point size no longer are the same height.


Thin letter "a" and thick letter "a"

Type creators go to great lengths to tweak letter forms so that thick and thin letters both “work.” In the example below, notice how the width of the lines making up the thin letter are uniform, but the lines making up the thick letter vary. It’s particularly noticeable where the bottom loop connects with the right vertical.

Thin letter "a" and black letter "a"

Here’s another way of comparing the light and black weights.

Thin "a" superimposed on black weight "a".

In the past, you were limited in your choices by the number of specific weights a type designer decided to create and release. If the designer made medium and black weights, too bad in you wanted a thin weight. If their “thin” was too thin and the next step up was too thick, you had no options.

Variable fonts let you change the weight of letters as little or as much as you want. Instead of buying half a dozen separate fonts, you can buy one and scale it to your needs.

In the examples above, the letter “a” came from “Thin” and “Black” weights. But a single variable font lets me go all the way from one to the other.

In CorelDraw, variable fonts are controlled by a simple sliding bar that appears when a variable font is selected.

For this particular font (Goldman Sans VF), the “Weight” goes from 200 to 900. I do not know what those numbers signify. They vary from font to font.

But wait! It gets even better! Some variable fonts allow you to control the width, too!

The word "Thinner" with descreasing width and weight with each letter

Again, the numbers presented as options have seemingly arbitrary high and low points. Width for this font, Bahnschrift, vary from 75 to 100. I think those numbers are set by the type designer.

But wait! There’s more! Some variable fonts allow you to control the slant, too! I don’t have an example myself, but it is mentioned in the description for Sharpe Variable

Photoshop, Illustrator, and Indesign: Powerful variable font technology. Use sliders to set any weight and slant

The price for variable fonts is, not surprisingly, higher than individual fonts. But you have to realize that a single variable font can take the place of two, three, or more fonts and give you finer control over the letters.

I happen to have used a couple of fairly conservative sans serif fonts here, but more and more variable fonts are being released. Some new, elaborate, beautiful script and display fonts are coming out. Some old classics like Univers have been upgraded with variable fonts. You can filter Google Fonts to show only variable fonts.

The font names usually specifically say, “Variable” in them. So searching for that word in a font shop will usually bring up fonts with that option.

Having said all this, you probably would not need to use variable fonts on a poster very often. Usually I’m telling people to pull back on the variation in their text, not add even more. But it is always nice to know what your options are.

Posters from before they were famous: A dream project

 Recognize the woman below? (It might be easier if you’re American.)

Alexandria Ocasio-Cortez with her Intel 2007 science fair project.

Alexandria Ocasio-Cortez with her Intel 2007 science fair project and Yorktown high school teacher Michael Bluegrass.

Alexandria explaining her project to Craig Barrett, retired Chief Executive Officer/Chairman of the Board, Intel Corporation and Society Board of Trustees member.

It’s federal politician Alexandria Ocasio-Cortez, eleven years before she was elected to the American House of Representatives in 2018. When she was in high school, Ocasio-Cortez was a second place finisher in her category in the 2007 International Science and Engineer Fair.

Yes, technically she is not presenting a poster, she is presenting a tri-fold. But I will let it go to make my point.

Lots of people present posters at conferences. Some of them go on to become better known than the average student. 

Ocasio-Cortez is unusual but not alone in being a politcian in her science background. German Chancellor Angela Merkel had a scientific career. Before that, Margaret Thatcher did an undergraduate chemistry dissertation.

I once spotted a poster co-authored by filmmaker James Cameron (whose interest in deep sea exploration is well known; pretty sure he only contributed samples and was not involved in making the poster).

Many well-known scientists have probably given posters at some point in their careers, too. Nobel prize winners have given posters. Science communicators who write books and appear on late-night talk shows have given posters. You know, the “rock star” scientists.

I wonder if Carl Sagan ever gave a poster.

I would love a project that showed these people with their posters. I would love to hear them talk about their poster session experiences. I would love to show students, “Look, what you’re doing is something that even science ‘celebrities’ did. They made posters, too.”

Sunday scraps: Third book cover draft

 We went through a few iterations of the “icon” cover that I showed last week.

I asked to see a few colour variations and got them.

The red was my favourite.

Some subtleties that I appreciated: 

The crayfish / lobster icon, a nod to my own area of biological research.

The flow of icons from top to bottom sort of follow the poster making process. The things you observe as a scientist are up at the top. The tools that you use to make a poster are down at the bottom.

The cover designer went back more to the concept of “make the cover a poster” is a less literal way than I had first tinkered with.

Conference posters books: the numbers

Scientist’s Guide to Poster Presentations: 128 pages. Academic & Scientific Poster Presentation: 170 pages. Better Posters: 305 pages.

As far as I know, there have only been three books specifically about conference posters ever. I wondered how they compared.

Title Author Year Pages Figures
Scientist’s Guide to Poster Presentations Peter J. Gosling 1999 128 ?
Academic & Scientific Poster Presentation: A Modern Comprehensive Guide Nicholas Rowe 2017 170 26
Better Posters: Plan, Design, and Present an Academic Poster Zen Faulkes 2021 305 153

I’m not saying mine is the best. But it it is the biggest to date.
