A Clean Calculus Joke
The change of position over time is velocity.
The change of velocity over time is acceleration.
The change of acceleration over time is jerk.
And the change of jerk over time is an election.d

To Save The Science Poster, Researchers Want To Kill It And Start Over
Professional conferences often feature poster sessions, and, more often than not, the poster is simply incomprehensible to somebody walking through the aisles.
So I enjoyed this article about an innovative way to bring scientific posters in the 21st century. The money quote:
“The current method is not effective in communicating research findings. For instance, in my field, we all want improvements in our life: vaccines for all diseases, easier delivery of vaccines, innovative way to finance vaccines, effective ways tackling vaccine hesitancy,” Suharlim says. “Experts are all coming to these conferences, and they have limited time to update their knowledge.”
The proof is definitely in the pudding:
Finally, here’s a YouTube video explaining the concept:

Another poorly written word problem (Part 11)
Another bonehead word problem. Notice the word “her”. While Usain Bolt holds the current 100-meter world record of 9.58 seconds, the women’s world record is currently 10.49 seconds.
