Beach Picture Craft Camp Update
Hello mathematicians, puzzlers, and other curious people! Meetings at the Day Job and the accompanying logistical matters have taken up so much time and energy that I\’m sorry to have to inform you I don\’t think I will have the next step in the picture (putting waves in the ocean) ready today. Please keep an…
Sun and Umbrellas: Beach Picture Craft Camp Video 3
Hello mathematicians, puzzlers, and other curious people! In this video, you can see how to add the sun and some umbrellas to your picture. Does anyone see how you could use the umbrellas to prove the same formula we proved with the seashells last time? Let me know if you figure it out! Calc You…
Seashells: Beach Picture Craft Camp Video 2
Hello mathematicians, puzzlers, and other curious people! This video shows the next step in assembling our beach pictures, putting some seashells in the sand. The next step will be up tomorrow, provided things go smoothly (or at least manageably). I\’ll also post a proof of that important fact about the inner angle sum of a…
Sand, Sea, and Sky: Beach Picture Craft Camp Video 1
Hello mathematicians, puzzlers, and other curious people! This video shows how to set up a background representing sand, sea, and sky so you can get started. Keep your eyes open, because the next step will be up soon. Calc You Later!
Beach Picture Update
Hello mathematicians, puzzlers, and other curious people! A video lag issue threw off my production schedule. Troubleshooting was eventually successful but it will be tomorrow before I can release a good version of the first beach picture how-to video. The project is delayed, not cancelled. I will post both of the first two steps tomorrow…
Number Code Puzzle
Hello mathematicians, puzzlers, and other curious people! For your entertainment, here\’s a puzzle that was posted in a math group on Facebook. (Wording adapted a little.) How many unique three-digit codes can be formed, using the digits 3, 4, 5, 6, 7, 8, and 9 following the rules below? code must be between 400 and…
Fractal Trees
Hello mathematicians, puzzlers, and other curious people! I\’ve learned a lot about making videos since this one, but I\’m posting it anyway in case anyone wants to draw some fractal trees to pass the time. I\’m looking for a good plugin for organizing a gallery for anyone who wants to contribute to it, but until…
Beach Picture Craft Camp: Supply List
Hello mathematicians, puzzlers, and other curious people! Under the circumstances, please do not make an extra trip to the store for any of this. I will make sure that there is an option to use free online technology for all of it. However, if you have to go to the store anyway, or you want…
GeoGebra: Dynamic Color
Hello mathematicians, puzzlers, and other curious people! In this video I show how to experiment with dynamic color in GeoGebra. I\’d really like to see some things folks come up with this way! Carefully take a screenshot and feel free to post it in the comments. Calc You Later!
Multiplying Square Numbers
Hello mathematicians, puzzlers, and other curious people! Following up this previous post on square numbers, in this video I take a look at what happens when two square numbers are multiplied. As you can see, when you think you\’ve found a number pattern, formulas can help with showing whether that pattern will always work or…
