...which has reference #14 has Sen listed as the author of another article (can't find direct link), here's #14 though: Sen, C. K. & Ghatak, S. miRNA control of tissue repair and regeneration. Am. J. Pathol. 185, 2629–2640 (2015).

I practice taijiquan, a martial art. My teacher often describes concepts that I can relate to basic mechanics. When I do, it feels like I understand, but as my teacher says -- until you can actually express it with your body, you don't really understand.

For example, a lever seems conceptually simple, but to create a lever in the body is extraordinarily hard. The joints have to be solidly connected and free to open or close. The direction must be precise and rotation must not wobble. There are so many things that can err and lots of places for force to leak out.

I thought Michael Moore's reasons were pretty on point: http://michaelmoore.com/trumpwillwin/

Michigan, Ohio, Pennsylvania and Wisconsin were indeed critical to the election, though it was by a hair that Trump won.

The liberal vote was not very enthusiastic, whereas Trump pulled in people that were die-hard fans.

Wow, this is eerily prescient and the best explanation I've seen so far of the Trump phenomenon. Great read for someone like me who like so many others, didn't know a single person voting for Trump.

I only use the search when I know what app I'm looking for. Wouldn't that would drive up the numbers artificially -- as I had the intention of downloading the app before I began searching.

Exactly, the statistic you need is "how many downloads came through keyword searches that weren't the app name".

I wouldn't think so, not if they're saying a percentage of all downloads come from search, as opposed to a percentage of all searches lead to a download.

But searching is the only way (sane) people find anything on the App Store. When was the last time you browsed the store until you found the cool new app you just read about?

Whenever I use the App store, I'm on a mission. But it's also a mission to get free stuff, so maybe I'm not even part of the equation.

I agree. Whenever I download an app it's because I read or heard about it somewhere else. Open the app store, head to search, type name, tap install.

I don't think I've casually browsed around the app store since I got my first iPhone (first smartphone), around 2009 or 10.

Me too. But I am skeptical of free stuff and almost always look for a paid version.

It's also how muscles work, isn't it? A ton of tiny myosin heads pulling in parallel.

Show me a society that is pure anything. Capitalism is an idea among many ideas that influence society -- pure capitalism doesn't exist in the real world.

Funny story I have with Dropbox:

I was setting up my new desktop to dual boot Debian and Windows. In the interest of saving space, I tried to have Dropbox in both systems target the same directory to sync. I'm not precisely sure what happened - I think the folder hadn't finished pulling in all the files before I logged out - but it somehow trashed everything in my lab's shared directory. Thank god for their API and their automatic file versioning, or I would never have gotten out of that pickle.

Being able to read English is a different skill from being able to write it. A lot of the Chinese students I know can understand it mostly fine but have trouble writing coherently for an English reader.
