This does not affect the price you pay. By way of history, I started the Mind Your Decisions blog back in to share a bit of math, personal finance, personal thoughts, and game theory. It's been quite a journey!
I thank everyone that has shared my work, and I am very grateful for coverage in the press , including the Shorty Awards, The Telegraph, Freakonomics, and many other popular outlets. People often ask how I make the videos. Like many YouTubers I use popular software to prepare my videos. You can search for animation software tutorials on YouTube to learn how to make videos.
Be prepared--animation is time consuming and software can be expensive! Feel free to send me an email [email protected]. If you purchase through these links, I may be compensated for purchases made on Amazon. The Joy of Game Theory shows how you can use math to out-think your competition. The Irrationality Illusion: How To Make Smart Decisions And Overcome Bias is a handbook that explains the many ways we are biased about decision-making and offers techniques to make smart decisions.
The Best Mental Math Tricks teaches how you can look like a math genius by solving problems in your head rated 4. Multiply Numbers By Drawing Lines This book is a reference guide for my video that has over 1 million views on a geometric method to multiply numbers. Mind Your Puzzles is a collection of the three "Math Puzzles" books, volumes 1, 2, and 3. The puzzles topics include the mathematical subjects including geometry, probability, logic, and game theory. Math Puzzles Volume 1 features classic brain teasers and riddles with complete solutions for problems in counting, geometry, probability, and game theory.
Volume 1 is rated 4. Math Puzzles Volume 2 is a sequel book with more great problems. Math Puzzles Volume 3 is the third in the series. Teachers and students around the world often email me about the books.
Since education can have such a huge impact, I try to make the ebooks available as widely as possible at as low a price as possible. Currently you can read most of my ebooks through Amazon's "Kindle Unlimited" program.
Included in the subscription you will get access to millions of ebooks. I have compiled links to programs in some countries below. Please check your local Amazon website for availability and program terms.
Here are some guidelines for using PowerPoint. Tick the Snap objects to grid and the display grid on screen boxes. Select from the dropdown box a spacing of 1cm. The red and blue right-angled triangles can be made using the "Right Triangle" tool which can be found in the Home tab, in the Drawing group. The green and yellow shapes can be created by putting together a number of 1cm by 1cm squares. Upon completion of the shape drag over the shape to select all of the squares then select "Group" from the Format tab, Arrange group.
Turn the Snap To Grid option off an add custom animations to each of the shapes to make the first arrangement of shapes transform into the second. The images on this page are from the Wikimedia Commons. I think this throws the students off a possible thinking path.
If instead it referred to the shape less specifically, then students might more readily venture down this path. Transum, Good point David. The phrase 'right-angled triangles' has now been replaced with the word 'shapes' in the text above. Thanks very much for the suggestion. Tara, Brisbane Was trying to plan a good lesson for ratio. The four figures the yellow, red, blue and green shapes total 32 units of area, but the triangles are 13 wide and 5 tall, which equals The blue triangle has a ratio of , while the red triangle has the ratio , and these are not the same ratio.
So the apparent combined hypotenuse in each figure is actually bent. Ever since it has been known as Curry's paradox. The principle of a dissection paradox has however been known since the s. The integer dimensions of the parts of the puzzle 2, 3, 5, 8, 13 are successive Fibonacci numbers. Many other geometric dissection puzzles are based on a few simple properties of the famous Fibonacci sequence.
