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:

A Quick Message to the UNT College of Science Class of 2020

We interrupt our regular programming for this quick message to the University of North Texas College of Science Class of 2020, whose graduation we had planned to celebrate this weekend.

250,000 page views

I’m taking a break from my usual posts on mathematics and mathematics education to note a symbolic milestone: meangreenmath.com has had more than 250,000 total page views since its inception in June 2013. Many thanks to the followers of this blog, and I hope that you’ll continue to find this blog to be a useful resource to you.

If I’m still here at that time, I’ll make a summary post like this again when this blog has over 500,000 page views.

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.

Trigonometry for the heavens

Codes and Ciphers Teaching Resources Website

Somehow I found this fun website with various teaching resources using different coding and decoding methods: http://www.cimt.org.uk/resources/codes/?fbclid=IwAR2yX_yDK0UAmLB2acIgbk15wJMy_QXFJSuKaQOj3q-SlrFkuuuxpsEXoyI

Slightly Incorrect Ugly Mathematical Christmas T-Shirts: Part 3

Here’s another T-shirt that I found in my quest for the perfect ugly mathematical Christmas sweater: https://www.amazon.com/Fibonacci-Christmas-Tree-Holiday-Shirt/dp/B07KCF1F6D/

Unlike the shirt in my previous post, this one actually gets the first ten rows of Pascal’s triangle correct. So that’s a good thing.

There’s one small error: while the Fibonacci numbers can be found by adding along shallow diagonals of Pascal’s triangle, this really shouldn’t be called a “Fibonacci Christmas Tree.”

Oops.

The Professor vs. the NSA

I didn’t know this interesting bit of internet history:

“It’s July 1977,” Hellman tells the audience. “Whit and I are involved in a major fight with NSA over the data encryption standard.”

American law banned the unlicensed export of weapons. Makes sense: the government doesn’t want civilians wandering into Moscow with a trenchcoat full of fighter jet parts. The question is: Does this law apply to abstract mathematical ideas? By developing new approaches to cryptography, are Hellman, Diffie, and their collaborators de facto arms traffickers? If so, Hellman says, “then by publishing our papers in international journals, we are in some sense exporting plans for implements of war.”

“I think the penalty,” Hellman recalls, “was something like five years in jail.”
