Forest without trees

Kelp forests like this in the Monterey Bay National Marine Sanctuary are the first thing I think of when I think about diving. This is #home.

Posted by @noaasanctuaries on Instagram in honor of #ArborDay.

“Happy #ArborDay! Our underwater marine sanctuaries may not have #trees, but they do have forests. #Kelpforests, like the ones found in Monterey Bay…”

Thanks +Andrea Chen! I've been diving at Lover's Point many times. The kelp becomes much more fun when you are swimming through the "forest" below the surface instead of negotiating the thick canopy at the surface :)

Wonderful brief animations of mechanical linkages at work. Some are quite complex and some are simpler, but all solve a problem of converting one motion to another, and many are brilliant.

I think my favorites are
Persian joint: http://youtu.be/mFoiSRWdW5E
Archimedean drive: http://youtu.be/r0AO8t-z3SI
Keeping direction unchanged during rotation: http://youtu.be/P-BaJiRCg68
 
Prepare to lose the rest of your day watching these animated diagrams of mechanical linkages. http://ow.ly/LSqqH

You probably know octopus can learn to unscrew jar lids to get to food inside. Here is the view from inside the jar, via +California Academy of Sciences's Steinhart Aquarium (which apparently only made the video available via their Facebook page)

Check out a view from the inside of a jar that one of our octopus opens to get its lunch. This kind of behavior keeps the octopus enriched and engaged in...

Swearing and pain tolerance

From the abstract:
This article presents further evidence that, for many people, swearing (cursing) provides readily available and effective relief from pain. However, overuse of swearing in everyday situations lessens its effectiveness as a short-term intervention to reduce pain.

The obvious next question: does the increase in pain tolerance scale with the saltiness of the language? The authors' idea that the mechanism is emotion-mediated suggests the answer would be "yes."
 
Swearing infrequently increases its efficacy as a pain reducer. #Seriously.

http://www.ncbi.nlm.nih.gov/pubmed/22078790 

the higher the daily swearing frequency, the less was the benefit for pain tolerance when swearing, compared with when not swearing
J Pain. 2011 Dec;12(12):1274-81. doi: 10.1016/j.jpain.2011.09.004. Epub 2011 Nov 11.

+Norka Patricia Sandi - what you say may largely be true, but the point of this research and other work (eg see http://en.m.wikipedia.org/wiki/Profanity) is that swearing can serve a function, especially when not casually overused.

The Most Übermensch Man in the World

The universe repeats itself eternally, just to witness his life again and again
This comic is a mash-up of Nietzsche's ideas of the Ubermensch, and the "Most Interesting Man in the World" advertisements. Of course, Nietzsche's Ubermensch isn't exactly the hyper-masculine ideal that is presented in the ads, but rather someone who is able to "overcome" his humanity and strive ...

Why academic freedom is not an excuse for Columbia to keep Dr. Oz on its faculty
 
Dr. Oz is under fire again, this time from a group of 10 physicians who wrote a letter to Columbia medical school reporting their dismay that he remains on faculty. Columbia came back with the expe...

Columbia probably can't actually fire him, because tenure rules (which I support) protect faculty expressing even idiotic ideas, but Oz should definitely be removed from his administrative position at Columbia, since it gives him additional influence and status beyond his faculty position.

+Peter Schmidt - that may sound like a contradiction, but it is not, and it is a quite reasonable part of science in action. There is nothing wrong with having strong confidence in some conclusions from a model while acknowledging other uncertainties. From the linked article:
"Although climate scientists agree on the basics — for example, climate change is primarily the result of human activity — large uncertainties persist in ‘climate sensitivity’, the increase in average global temperature caused by a given rise in the concentration of carbon dioxide."

Contours: straight lines projected onto curved surfaces
 
Curved Light
While cleaning I noticed the light from the blinds in the living room cast lovely curved in a composition all the way down to the large stack of art paper setting on the bookcase.  The original iPhone 6 Plus photo shows the detail of the sheer curtain over the blinds in the full size.  Black and white filter added in Lightroom 5.5.
