I really should post my timelapse one of these days :)
“So is this little flyer supposed to tell me something?”
On the sofa, reading that month’s Bulletin of Crime Scene Study, Sherlock remained mute.
About an hour later John said, “Well I do quite like the chelsea, monk strap, and wing tip styles.”
Sherlock just smiled.
Neil deGrasse Tyson words to live by.
People are entitled to their own opinions, but not their own facts. Do not hesitate to remind them of this.
You know, politely.
Thank you, Jane Henson <3
My short ode to development, inspired by the image above, (via biocanvas):
Epithelial cells line surfaces and cavities throughout the body, forming skin, glands, and tracts. This mouse embryo has been genetically engineered to allow for the visualization of epithelial cells, showing the pattern of whisker placement on the face.

The dance of biological development tops our best ballet or even our most magnificent marches. And it is truly a dance, as this video of a developing fruit fly embryo makes beautifully clear:
Those cells, darting to and fro! They are pulled in and out of furrows, sensing the position and identity of their neighbors, migrating and multiplying at the whim of invisibly overlapping chemical gradients. It’s a journey in both space and time, the emergence of greater form from a horde of interconnected individuals.
The whisker patterns of the mouse above are just one of the many awe-inspiring end results of developmental organization. While only a few of those nodes will sprout whiskers, the larger pattern drawn by development can be seen radiating outward toward the tail like rays from the sun.
These relics of organization often remain invisible in adult animals, although sometimes they do show through (like when humans have “stripes”). Jason Silva has said that “to understand is to perceive patterns.” I offer this as an accompanying idea: To exist at all is to emerge from the sum of patterns.
I *will* learn crochet to do this!
a little nudibranch i crochet and later turned into a bracelet :)
Col. Chris Hadfield returns to Earth tomorrow after nearly five months in command of the International Space Station. Here are his touching personal reflections on the mission.
His stay on the ISS has captured the imagination and the curiosity of millions of people on Earth, thanks to this wonderfully interconnected world we call social media. Not only do we have the technology to send men to space for months at a time, but they can share that experience so richly with all of us.
I am truly grateful for his hard work, the hard work of people like his son Evan (who managed his dad’s Tumblr and much of his other social media) and the hard work of those who continue to support the mission. He went to space so we could ALL go to space.
Celebrate with the ten best videos from Commander Hadfield’s time aboard the ISS. I know what my favorite was (also in GIF form).
