If you have been participating in Summer of Math Exposition voting, remember this is the last full day of voting for the phase-2 voting portion of the contest!

In recent years some voters have been increasingly unsatisfied with two-party systems in USA. In 2016, neither of the two party candidates could get a majority of votes of the American people. In 2000, one third party candidate ended up making a big difference in the total, because as in most voting systems, one can only vote for one person for each position.

SOME (Summer of Math Exposition) is happening again this year – a contest without a big prize, but of course the winner is everyone when we build some new math posts and videos for students learning…

If you live in Oregon you may have seen one of these research papers mailed to you along with a short letter promoting Noah Robinson for Oregon senate. Since this report is claimed on the campaign website to be “the most widely read scientific review article on “climate change,” which shows that human use of hydrocarbon fuels like gasoline is not changing the earth’s climate“, and the data in the charts ends at about the year 2000 for many charts as of its publishing, I decided to get some more recent data to research the most recent trends:

Green-screening a recursive green screen for a unique Pie-day effect
If you’ve seen any behind-the-scenes view of any movie you probably are familiar with the green-screen – generally a way to combine an actor with some prerecorded or computer generated background. There are some unique effects you can do with this yourself using OpenCV!

Last week it was announced that high flu cases are having effects on the health system in Jackson County, Oregon. A top recommendation on the OPB article says to get vaccinated for Flu – does this recommendation play out in the statistical data though?

Months ago you may have seen the new shape that does not periodically tile (repeat) like most other shapes, in the plane. However, that is assuming an infinite (x,y) plane… What if instead of that geometry, we try building out a periodic cylindrical tiling?

This year the Bay Area Maker Faire was back after years of postponement! This was an enormous fair compared to others I had attended and included some very interesting exhibits:
