Cosmos: A Spacetime Odyssey
Cosmos: A Spacetime Odyssey [https://en.wikipedia.org/wiki/Cosmos:_A_Spacetime_Odyssey]

My family and I have thoroughly enjoyed watching "Cosmos: A Spacetime Odyssey", the recently concluded 13 episode science documentary TV series. A sincere thank you to Neil deGrasse Tyson, Seth MacFarlane, Ann Druyan, Fox, the National Geographic Channel, and the many who worked on Cosmos.

The show was thoroughly aligned with content my wife and I encourage for our kids. A sense of curiosity and wonder. Openness to different ideas and people. Awareness of the danger and responsibility of climate change: A climate change of a few degrees (or a few ppb of CO2) leads to an Ice Age or a Heat Age. The beauty and explanatory power of evolution. The importance of epistemology and the scientific method, and how it can stray.

I'll conclude with five simple rules that Neil mentioned in the last episode.

  1. Question authority. No idea is true just because someone says so, including me.
  2. Think for yourself. Question yourself.
  3. Don't believe anything just because you want to. Believing something doesn't make it so.
  4. Test ideas by the evidence gained from observation and experiment. If a favorite idea fails a well-designed test, it's wrong! Get over it. Follow the evidence, wherever it leads. If you have no evidence, reserve judgment.
  5. And perhaps the most important rule of all: Remember, you could be wrong.

Neil deGrasse Tyson explains why the new Cosmos matters so much
Neil deGrasse Tyson explains why the new Cosmos matters so much [http://io9.com/neil-degrasse-tyson-explains-why-the-new-cosmos-matters-1534876280]
We've been distracted by the stunning advances that information technology has brought us, to the exclusion of very deeply held needs that we have in society.

In college I could barely do chemical engineering because I was so distracted by computers! The Web wasn't even up then, so people have even more distractions now.

Cosmos has, as its mission statement, the effort to convey to you why science matters. That is a different motivating factor than "Here's all this science I want to teach you."

There is so much mind in science that people forget that it has so much heart in it too.

Notes on Meetup with Health Data Liberation

Last night I attended the inaugral meeting [http://www.meetup.com/Health-Data-Liberation/events/156222932/] of the Meetup group "Health Data Liberation" [http://www.meetup.com/Health-Data-Liberation/]. The meeting was run by Dr Rebecca Wurtz, an Epidemiologist at Northwestern. 2-3 dozen attended including doctors, folks in BI & analytics, several in the open data movement, a fellow from payers, etc. There was a vigorous and enthusiastic discussion, that was not dominated by any one individual.

There was much discussed, and I just want to hit on a few key points.

Issue: Trust. Different systems already have our data. But who do we trust to merge data? How can we trust them? The data merging entity would have to promise to be the end-of-line as far as identified data, if they want to share the merged data, then they could only share de-identified data. The entity would have to have strong security and impoorting arrangements. Each person would have the right to their own data and to pull out at any time.

Issue: De-identifying data. There was much involved in suspending disbelief that we could actually de-identify data --especially once a data set has been merged with other data sets. The HIPAA standard for de-identification (45 CFR 164.514) does not stop people from using their Sherlock skills to identify people in merged data sets without the name, gender, address, date of birth, etc.

Issue: Name. It also became apparent that since we want the data to be as wide and complete as possible. The term "health data" is too restrictive. Perhaps "life data"?

Issue: Falsified data. We may like the concept of the quantified self, but did you really do 1000 push ups in 30 minutes today? It seems that we need external parties to provide some degree of validation of the data.

Issue: Select which data sets to share. People may be OK sharing most health data but not genomic data or book purchases. The People should be able to choose which data set (hospital, pharmacy, payers, labs, medical & exercise devices, Google, Amazon, genome, banks, utilities, etc) they want merged into the open data set. They should be able to do this in batches or stream, scheduled or one-offs.

Issue: Sharing data. I'm guessing that this will probably go the Semantic Web route with RDF, but in the meantime we have to deal with HL7 v2, HL7 v3, HL7 FHIR, EDI 837s, XDS, etc, etc. And that's not even talking about the non-health data sources.

Issue: Analysis. Open life data is in the twilight zone between collecting data and analyzing it. While systems already collect and analyze internal & proprietary data, no one is up to sharing the data for de-identification and open analysis yet. We didn't discuss the kinds of open analysis that could be done, but perhaps that would need to be a separate discussion because the other issues overshadow this one.

Issue: Starting. My guess is we'd have to start with small set of people who volunteer to make their life data open (but de-identified!) at some site X. Then they can choose which data sets to share their identified data with X. Site X would merge different identified data set but only share a de-identified data set to anyone. If successful, then there will probably be ways to incentivize people to participate in the data liberation.

Find beauty with the mind and heart, as well as the eyes, mouth, and ears.

This morning I walked by a building where some parts were covered with with windows and other parts with embedded stones. I saw people with window-washing scaffolding on the stone parts, so I assume that they were not window-washing but stone-washing.

An image popped into my mind of mountain water running over mountain stones. An image of water cleaning stones year after year, scrubbing stones down molecules at a time. I found it to be a beautiful concept. It was natural, clean, out of the city. It was redemption of mind, a renewal of spirit. The concept of it was more beautiful than the image.

Find beauty with the mind and heart, as well as the eyes, mouth, and ears.

Memory: What is it like to have a photographic (eidetic) memory?
Memory: What is it like to have a photographic (eidetic) memory? [http://www.quora.com/Memory/What-is-it-like-to-have-a-photographic-eidetic-memory]

An eidetic memory, open books, the Web, and Google help, but it's still mostly about problem solving. We start with solving simple problems often enough to integrate the solutions as the basics. Then we use the basics to solve more complex "level 2" problems. If you solve level 2 problems often enough, then you start building a repertoire of level 2 basics.

I can't stand memorizing and working, but I do like integrating and playing. Developing a repertoire of ever higher level basics sounds like work. If I trick myself into thinking of it as play, then I can do it. If I become conscious that I am tricking myself, then it becomes work again. The solution is that it can't be a trick -- it has to be earnest play. Or the problem has to be so important, so tantalizing, that you practically need to build the repertoire that allows you to progress on solving the problem.

Gmail Categories

Gmail had Labels and Filters. Then it added Smartlabels (Bulk, Notification, and Forum) in Labs (and is still in Labs). Then it added Categories as Tabs and Labels (Primary, Social, Promotions, Updates, Forums) not through labs (possibly because it's the "graduate" version of Smartlabels).

I've been using Gmail's tabbed Categories for a few weeks now and I have been fairly satisfied. It has convinced me to get rid of a few labels and filters that I had before. For example: I used to have a Label and Filter I called "ADMIN", but it effectively functioned like "Notification" in Smartlabels, which in effectively functioned like the "Updates" Category.

However, there's always something. Here are three minor issues I have Categories so far:

1. Occasionally a new message will appear in the west for a Category Label, but will not appear in the Category Inbox Tab. Odd and a little annoying. Possibly just an asynchronous issue.

2. My guess that Gmail starts with what it thinks should go in each Category. Gmail probably starts by pre-identifying known social sources (like Facebook, Twitter, and Google Plus), promotional sources (like Amazon, Microsoft Store, and GrubHub), and update sources (like banks, Mint, and credit cards). Then Gmail probably learns which sources should go in which Category after you drag them into another Category several times. HOWEVER, I have been dragging emails from one Category Inbox Tab to another, but Gmail seems to be slow on learning my preferences.

3. When you have an email open in one Category Inbox Tab and switch to another, Gmail keeps that email open. Some people may like that, but I think it's a bit confusing to step away from Gmail for (gasp!) a few minutes, and then come back to find some email open that is not part of the currently selected Category Inbox Tab.

Over all, Categories automatically gives lots of people functionality that was only available to "power users" that tweaked their Gmail account.
