I just happened to have stumbled upon this YT channel the other day, and wound up spending nearly 3 hours on it. Obviously, I enjoy it. Since today is Pi Day (3.14), thought I'd share this one. But there's loads more interesting things to be seen on the channel, including nine more videos about Pi itself, and Dragon Curves, and base 12, and lots of other fun math-y things. Even if you're not a math geek, it's more fun than you probably think it sounds.

Andrew 's description from his Vimeo post:
"A moving infrared timelapse movie.
This is a personal project culminated from years of shooting IR stills and never really being satisfied with the results. Shot primarily in Albemarle County, Virginia, the movie was captured using a Canon 5D mark II converted with a 720nm IR filter over the sensor. The sensor filter allows normal camera operation but shoots only IR images. I used a rail from Dynamic Perception to create the moving images and processed everything in Adode Premiere/After Effects.
Check out my website andrewshurtleff.com to see some cool IR stills under the fine arts section. Thanks for watching."

According to Dr Lykken, via BBC News:
"It turns out there's a calculation you can do in our Standard Model of particle physics, once you know the mass of the Higgs boson," - "If you use all the physics we know now, and you do this straightforward calculation - it's bad news." - "What happens is you get just a quantum fluctuation that makes a tiny bubble of the vacuum the Universe really wants to be in. And because it's a lower-energy state, this bubble will then expand, basically at the speed of light, and sweep everything before it,"
As best as I understand all of this. One of the debated physical properties of the universe in which we all live, is that the vacuum in which said universe exists, is not as stable as it could be. The notion that this instability is one of the physical properties of our current universe, isn't a new one. But determining weather or not this theory is true, is all based on a calculation involving the frequency of the higgs' own mass, versus that of the top quark's pole mass, amongst other things. If our current understandings of those measurements and calculations hold true, then it's possible that at some point in the distant future - as in, an incomprehensibly long time from now- a fluctuation within the field which maintains said vacuum, could cause it to re-align itself into a more stable state. Meaning; The universe in which we currently live, will be no more. Which sounds bad. But, again, you're gonna be dead anyway. So don't worry too much about that. Besides which, the calculations described by DR. Lykken also bring with them another possibility: What if the end, is really just the beginning?
"It's much easier to explain a lot of things if what we see is a cycle. If I were to bet my own money on it, I'd bet the cyclic idea is right," - Dr.Joseph Lykken [BBC]
