Who is the REAL star of “Friends”?

23-friends-cover-story-lede.w1200.h630

A data scientist studied the transcripts for every episode of the hit TV show Friends to try and determine who the real “star” of the show is.  Which Friend is the show really about? Read the article to find out more.

BADGING:

Assuming you are familiar with the show Friends (why are you doing this badge otherwise?!  There are plenty of others that might interest you more!), write a short paragraph explaining which Friend you think is the main character of the show.  Explain your reasons for making that choice.

Then read the article linked above.

In a second paragraph, explain the data scientist’s reasoning for making his choice.  Include the five categories (graph headings) that he studied and how they helped him to arrive at his conclusion.

Then, in a final paragraph, state a data point that you think the data scientist should have also included to help make his decision.  What other information do you think could help decide who the most important character is on Friends?  Do you think including this information would change the results of the study?

Women are better than men at free throws

18delledonneweb1-articlelarge

The results of a 30-year study show that women NCAA basketball players shoot free throws more consistently than male NCAA basketball players.  See the findings here.

BADGING:

Before reading the article, make at least three hypotheses that you think might be the reason women tend to be “better” at free throws than men in the NCAA.

Then read the article linked above.

Below your hypotheses, write a paragraph explaining what the study found.  What appears to be the major factor in the women’s free throw consistency?  Compare this finding to your hypotheses.

Write a second paragraph stating another athletic comparison that you would like to see studied (for example, “Who makes free throws more consistently, left-handers or right-handers?”).  It doesn’t have to be a basketball comparison.  Explain why you think this comparison could be valuable to athletes and coaches.

W.E.B. DuBois at the World’s Fair

W.E.B. DuBois, the first African American to earn a doctorate from Harvard University, attended the World’s Fair in 1900 in Paris with some amazingly beautiful graphs (“Data Visualizations”) that showed what life was like for black folks in America at the end of the 1800’s.  Read about them and see the striking images by clicking here.

BADGING:

Read the article linked above.

Pick any three of the graphs from below the article that DuBois displayed at the World’s Fair.  For each of the three graphs you choose, answer these questions:

  1. What is the title of the graph?
  2. What aesthetic or artistic choices (colors, layout, design, etc.) did DuBois make in creating this graph?
  3. How did those choices from the previous question add to the visual appeal of the data?  Why is this graph more effective than just listing the data as a table or a list of numbers?

Then, write a single paragraph that summarizes what you learned about what life was like for African Americans in the USA at the end of the 1800s (especially in the South).  What was DuBois trying to show the world by bringing these graphs to the World Fair?

The Mathematics of the Black Panther

Shuri

As part of Chalkdust Magazine‘s celebration of Black Mathematician Month 2018, Dr. Nira Chamberlain discusses one of Shuri’s creations in Marvel’s Black Panther movie; T’challa’s suit, which supposedly disperses energy from impact blows and absorbs the shock to minimize damage.  Is this mathematically possible?  Read on to find out!

BADGING:

Read the article linked above.

In a paragraph, describe what would have to be true about a suit that disperses kinetic energy in the way that Black Panther’s suit does in the movie.  A suit like that hasn’t been invented yet, but a mathematical model has been made.  Describe in your own words what characteristics that suit would have in order to make the energy dispersal possible.

In a second paragraph, think of some movie tech that doesn’t yet exist (choose a favorite movie that contains some sci-fi or futuristic element to it).  If you were to make a theoretical model of that tech, what type of mathematical and scientific questions would you have to address before attempting to build a prototype?  For T’challa’s suit, mathematicians had to determine how to disperse the shock of impact.  What would have to be mathematically feasible for different movie tech?  Be sure to tell me what movie and what tech you’re discussing!

All You Need Is…Math?

UPDATE:  This video has been removed.  This badge is unavailable for now.  Will update later if it becomes available somewhere else.

The Beatles famously shared songwriting credits for all of their songs; throughout history, it’s been gradually revealed whether or not John Lennon or Paul McCartney wrote each famous Beatles song.  However, there’s one song that they were never able to agree on.  Hear how mathematicians have determined who actually wrote The Beatles’ hit “In My Life”.

BADGING:

Listen to the song above.  Then you should read this NPR article and/or listen to the interview (top left of page).

Write a brief paragraph summary explaining in your own words how mathematicians determined the authorship of “In My Life”.  Write a second paragraph hypothesizing:  Where else might this statistical method be used?  Think not just in music, but in the written word as well.  How might historians and archaeologists use this method in other instances?

Finally check out this post, wherein the author used a technique similar to “Bags of Words” to see if a machine could read recipes and create new ones.  The results are…interesting.
