A fascinating insight into why NASA's Jet Propulsion Laboratory only uses pi to the 15th decimal place (3.141592653589793). I like the second example the most:
We can bring this down to home with our planet Earth. It is 7,926 miles in diameter at the equator. The circumference then is 24,900 miles. That's how far you would travel if you circumnavigated the globe (and didn't worry about hills, valleys, obstacles like buildings, rest stops, waves on the ocean, etc.). How far off would your odometer be if you used the limited version of pi above? It would be off by the size of a molecule. There are many different kinds of molecules, of course, so they span a wide range of sizes, but I hope this gives you an idea. Another way to view this is that your error by not using more digits of pi would be 10,000 times thinner than a hair!
Given this perspective, it makes you wonder why things like this exist. ("Because we can!" Uh huh.) #
This was such a touching story, and I loved listening to it. What an open and inviting heart Mr. Rogers always displayed to all of us. It's only years after the fact that I've come to appreciate how different his approach was to life. What a good man to emulate in many ways. #
My boys aren't anywhere near the age of needing to build one (or have me build one, and them act like it was theirs). Regardless, I found this to be pretty interesting, and I love how it's possible to make a great car, in a relatively short amount of time. It feels like it leaves more time for the kids to make the car what they want... even though winning isn't everything (but it sure is nice). #
I really like DKNG's work, and own multiple prints from them. I also have a soft spot for patches (though, admittedly, I never do anything with them, apart from put them in a little "happy box", and look at them every now and then). As it is, the venn diagram represented by this new patch essentially guaranteed I would buy it. $6? Done. #
I was in the middle of doing the exact same thing as this guy (copying all of my movies to my computer so they would be accessible via AppleTV... instead of having my kids scratch the discs), and I got to a movie he mentioned - Lord of the Rings (and Dances with Wolves... though my kids don't watch either of those movies). I love named chapters in movies, and wanted to have both a combined file, and have chapters. Simple walk-through right here. The added bonus is him pointing the way to iDentify, since MetaX has become abandonware. #
Because you never know when you'll need a high quality photo of an awesome person/character. It shows here as square, but the original is gorgeous. Awesomeness. #
Just to prove how long I've kept some tabs open in my browser, this one dates back to June of 2014. Every now and then, I re-watch this looping gif, and love how the ball ends up in so many different places, with (seemingly) the exact same beginning. As a Dodgers fan, I love watching Clayton Kershaw pitch. #
Although I prefer the awesomeness of SpriteStitch.com, and the endless supply of patterns (not to mention helpful people), NERDpillo has made it one step closer to being done, by gathering all the supplies you'll need to actually make one of those awesome video game map cross-stitches. #
This Firefox Add-on came in really handy when Mozilla decided to remove one of my favorite features ((tab groups, RIP)[https://support.mozilla.org/en-US/kb/tab-groups-removal]). It, very effectively, will export all of your open tabs - exactly what I needed to grab my dozens of tabs across my handful of different tab groups (one tab group for the different way I was using my web browser at the time - super handy). So, long Firefox - I've had enough of you, and have been using Safari instead - it works perfectly between all of my devices, and doesn't feel like bloatware. #
Dealing with REST APIs can be a funky process, but the folks at LuckyMarmot have made this gorgeous-looking, really intuitive client for breaking down those barriers. #
