Did you know that the ancient Japanese art of paper folding (origami) is mathematical in nature? Did you know that NASA actually uses origami when designing spacecrafts? Watch the video above to learn more!
Watch the video above. In a short paragraph, summarize how NASA uses origami when designing spacecrafts. Then, visit THIS PAGE of origami instructions to create any flower of your choice (if you don’t have suitable origami paper, Mr. Bezaire has some you can borrow). Include a picture of this origami creation in your Badge Google Doc. Then, write a second paragraph that describes different mathematical properties/ideas/concepts that you saw and experienced while making your origami creation.
Many people’s home computers sit idly during the day when homeowners are away at work or school. Did you know that some organizations allow you to connect your computer to a mainframe so that they can “borrow” bits of your operating power to work on difficult problems? The Charity Engine is one, and it helped to solve one of history’s great unsolved math problems.
Watch the the first 5 minutes of the Numberphile video embedded above, and then read this brief Popular Mechanics article.
Answer the following questions in a few sentences each:
- Describe the “sum of three cubes” problem (aka a “Diophantine equation”).
- Explain why some numbers (like 4 or 5) will never be written as a sum of three cubes. What mathematical property do these numbers share that makes them unwritable in this way?
- Why are 33 and 42 “special cases” when it comes to Diophantine equations?
- Explain how long it took computers to finally find a Diophantine solution to 33 and 42.
- Find any two Diophantine solutions/equations that weren’t shared in the video or the article.
Thanks to Mr. Victoria for sharing this article as a badging opportunity!
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.
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:
- What is the title of the graph?
- What aesthetic or artistic choices (colors, layout, design, etc.) did DuBois make in creating this graph?
- 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?
Thanks to Jason Kissel via Chris Nho for suggesting this badging opportunity!
“Can you believe what 56 did? It’s just so…odious!”
“Oh I know. And 43 is so lucky, I can’t even stand it.”
You probably know a lot of properties of numbers like “even”, “odd”, “prime”, “square”…but there are so many more that you might have never heard of! Head on over to Number Gossip to get the scoop!
Pick a favorite or interesting whole number. It might be your uniform/jersey number for a sport you play, or your home address, or your lucky number, or something else entirely. Enter it into the search field at Number Gossip.
- List all of the “common properties” of your number that Number Gossip lists. If any of those properties are unfamiliar to you, you should be able to click for an explanation. Explain in a sentence next to each property why your number belongs to that property (Where applicable, give a specific reason for *your* number, not just a definition of the property).
- Pick one “rare property” (if your number has one; not all do) and do the same thing as in step 1.
- Pick one “unique property” (if your number has one; not all do) and do the same thing as in step 1.
- Search Number Gossip for the whole number directly before and after the number you chose. How are the search results different? How are they similar? Write a few sentences comparing and contrasting, as well as your thoughts as to why they compare the way they do.
Certain schools on the Yucatan Peninsula in Mexico are teaching native students the mathematics that was done by their ancient ancestors in the Mayan civilization. Check it out in the video above.
Watch the video and pay attention to how the Mayans write their numbers and conduct simple arithmetic. Answer the following questions.
- How would you express the number 19 using the Mayan notation?
- In the video, the news reporter shows how to do the arithmetic 16 + 7. Replicate that arithmetic using drawings.
- Now create a drawing/notation using the Mayan method to conduct the arithmetic 18 + 6.
- Explain at least three reasons why it is important for these children to be taught this method of arithmetic alongside the “typical” methods (like the way you learned to do addition, for example).
The last time we saw Dr. Eugenia Cheng, she was on The Colbert Show cooking up some fun mathematical recipes.
This time, she’s on PBS talking about how the usefulness is math is…a burden? What could she possibly mean?
Visit the video to hear what she’s talking about.
Watch the video linked above (less than 4 minutes). Answer the following questions in a couple of paragraphs.
- Why does Dr. Cheng feel that we should let go of the idea that math is “useful”?
- What are some adjectives Dr. Cheng uses instead of “useful”?
- Dr. Cheng gives a number of examples of math that wasn’t “useful” until centuries after it was discovered. Describe a couple of those examples (internet cryptography, viruses, soccer balls, etc.).
- How does Dr. Cheng suggest we “break the cycle” of how students (particularly elementary students) view mathematics?
You may have heard that there’s a Presidential Election this year?
As this is one of the most hotly contested and emotional political races in recent memory, every facet of the election is going to be under scrutiny. One such facet is the Electoral College.
Mathematician John Allen Paulos wrote an opinion piece back before the 2012 Presidential Election for ABC News criticizing the Electoral College system. He posits that a candidate could conceivably lose the popular election 70,000,000 to 11 but still win the presidency.
Is that possible? Does this carry even more weight in 2016 than it did in 2012? Read on and see: http://abcnews.go.com/Technology/mitt-romney-barack-obama-win-eleven-votes-electoral/story?id=16470327
Read the article. Explain how a candidate could logically receive only 11 votes but still win the presidency. Write a paragraph explaining your feelings on the Electoral College (Do you think it is fair? Should we do it differently?). Then research one other free, democratic country and determine how their national leader is elected. (Example: Prime Minister of Britain, Japan, Canada, Australia, etc.)
Many people know that mathematicians have used their knowledge of numbers as an advantage when gambling (For example: http://www.sonypictures.com/movies/21/)
What we might not know is that a LOT of new mathematical knowledge was developed as a result of gambling or “games of chance”.
Check out the Guardian article here: https://www.theguardian.com/science/alexs-adventures-in-numberland/2016/may/05/seven-lucky-ways-that-gambling-changed-maths
Read the above article. Each of the 7 bullet points lists a mathematician (or two) that contributed to this new knowledge. Pick any three of the mathematicians listed. Summarize (from the article) what they did to promote a new mathematical understanding based on their “hobby” of gambling. Then research each mathematician online (Wikipedia is fine) and add a sentence or two (per mathematician) about what else they are known for (in mathematics or outside of mathematics).
Whoa: 538 (ESPN) has published a huge analytics piece on Sumo wrestling. Hakuho, a modern great yokozuna in the world of sumo wrestling has drawn comparisons to the historically great Raiden (a great wrestler from the 1700’s — centuries ago!). They analyze the careers of both wrestlers and try to determine who is the “greatest sumo wrestler of all time”
Check out the article here: http://fivethirtyeight.com/features/the-sumo-matchup-centuries-in-the-making/
Or dive deep into the data yourself here: http://projects.fivethirtyeight.com/sumo/
Read the article (first link above). Write a paragraph making the case for each wrestler (Hakuho and Raiden) being the greatest of all time (two paragraphs total). Find another all-time great wrestler (use a name from the article, or another sumo wrestler you may be familiar with for some inexplicable reason), research his career online, and estimate their place on all 6 graphs in the second link (screenshot each of the six graphs by using SHIFT-COMMAND-4, import them into your Word or a Google Doc that contains the above paragraphs and use a picture tool to place a mark where you think your wrestler “belongs” on each graph). Write a sentence that explains your wrestlers place in sumo history (average, below average, all time great, etc.)
Scientific American recently published an article celebrating three great and influential female mathematicians. Think all famous mathematicians are guys? Think again.
Check out the article here: http://blogs.scientificamerican.com/guest-blog/3-revolutionary-women-of-mathematics/
Read the article linked above. Pick out one of the three mathematicians and do further research on her online. Write a two-paragraph biography of her mathematical and other life accomplishments and include at least two interesting facts not included in the article that is linked above. Include a quote either by or about the mathematician you chose.
