Pianist and composer Nahre Sol attempts to play “Happy Birthday” in 16 levels of complexity. Nahre starts playing the iconic tune with just one finger and adds more and more layers until she’s playing it with extended harmonies, elongated melodies and staggered leaps. Watch and see how it all comes together!

16 Levels of Piano Composition: Easy to Complex
How to Stroke a Cat, According to Science
via Phys.org
This social shift in the human-cat relationship is thought to have occurred around 4,000 years ago—a little later than “man’s best friend” –- the domestic dog. Although this might seem like a sufficient amount of time for a species to fully adjust to increased social demands, this is unlikely to be the case for your feline friend. Domestic cats also display relatively modest genetic divergence from their ancestors, meaning their brains are probably still wired to think like a wildcat’s.
Wildcats live solitary lives and invest considerable time and effort communicating indirectly—via visual and chemical messages—just to avoid having to see each other. So it’s unlikely that domestic cats inherited many complex social skillsfrom their relatives.
20 Years Later, The Blair Witch Project is Still Creepy
How many of you remember people thinking this was real footage? No matter how you feel about the film, you have to admit it served as inspiration for movies like Paranormal Activity, The Witch, Cloverfield, and The Village. The Blair Witch Project is one of the most fascinating horror films of all time, even 20 years later.

In one of the most intense filmmaking experiences imaginable, actors Heather Donahue, Joshua Leonard, and Michael C. Williams played fictionalized versions of themselves, heading out to the Maryland woods to film a documentary about the legend of the Blair Witch. Part of what made The Blair Witch Project so groundbreaking is that you never see the actual Blair Witch, and the filmmakers didn’t use special effects to scare audiences; instead they had genuine reactions from a cast that didn’t know what awaited them in the woods. The film managed to do so much with so little, and it also introduced one of the first viral marketing campaigns, gaining a following before it even hit theaters. The Blair Witch Project turns 20 this week, so we spoke to the cast and crew to look back at the making one of the most legendary horror films of all time.

Brainpad adds robotics blocks to MakeCode #MakeCode #Robotics @brainpadboard @MSMakeCode
Brainpad has a wonderful education board which you can program using Microsoft MakeCode. In looking to support robotics, they look to build some standardized blocks that anyone might comfortably use:
Ever noticed how most beginner robots have the same purpose? Why not make a standard for blocks.
It is amazing to have so many robot options to choose from. More choices mean you can find what best suits your needs. Most beginner smart robot cars have 2 motors, same HC_SR04 distance sensor, 2 line sensors on the sides of the front wheel and some type of RGB lighting.
We decided that it would be nice to have a general code block set for these objects. So we went ahead and made it. Any robot we make in the future will follow this format.
See their post for more details.

How Fireflies Glow and What Signals They’re Sending
via Phys.org
You might not really be sure you saw what you think you saw when the first one shows up. But you stare in the direction of the flicker of light and there it is again—the first firefly of the evening. If you are in good firefly habitat, soon there are dozens, or even hundreds, of the insects flying about, flashing their mysterious signals.
Fireflies—alternatively known as lightning bugs in much of the United States—are neither flies nor bugs. They’re soft-winged beetles, related to click beetles and others. The most dramatic aspect of their biology is that they can produce light; this ability in a living organism, called bioluminescence, is relatively rare.
Amazing Photos Reveal the Hidden Light of Undersea Life
This is absolutely beautiful.

As I descend into dark waters, my blue flashlights reveal a spectacular display of fluorescent colors shining out from some of the corals and marine creatures below. Normally hard to detect with the naked eye, this secret, colorful light show gleams as brightly as an ’80s disco within the beam of my lights.
Fluorescence on the reef occurs as shorter wavelength blue light is absorbed by special proteins in tissues and is reemitted as longer wavelength greens, reds, oranges and yellows. While the ocean naturally filters light, leaving the underwater world cast predominantly in blue below 15 meters or so, the addition of concentrated blue light from the flashlights and flashguns attached to my camera rig stimulates the strongest response from the fluorescing proteins. Yellow filters on my lenses and dive mask block the stimulating blue light, enabling me to see and capture the full extent of the psychedelic spectacle.
