🔖 Mapping Uncertainty on the Oregon Trail

Mapping Uncertainty on the Oregon Trail by Anelise H. Shrout
In the early 1840s the American West, though claimed by the United States, was considered by many white Americans to be untamed, wild, and possibly rife with unknown wealth. This was a West that existed largely in the American imagination. In fact, the area west of the Missouri was home to complex Native societies, was divided into political structures, and was intimately known, if not formally mapped. These two competing Wests - that imagined by many Americans and that inhabited by Souix, Pawnee, Snake and Nez Pierce tribes - were mapped both geographically and textually by John C. Frémont between 1842 and 1843. Frémont set out from St. Louis in the summer of 1842, and began to chronicle his journey west, in the wake of "emigrants" who were moving to the Oregon Territory - a route known as the "Oregon Trail." Frémont's first expedition covered the land between the Missouri River and the Rocky Mountains during the summer and fall of 1842. In the summer of 1843 he set out to write an account of the second half of the Oregon Trail, from the Rocky Mountains to the Columbia River in Oregon. The maps contained here are drawn from the Library of Congress's collection "Topographical map of the road from Missouri to Oregon, commencing at the mouth of the Kansas in the Missouri River and ending at the mouth of the Walla-Wallah in the Columbia." They were created using Frémont's journal, and cover his first and second expeditions. I have annotated the maps with accounts of the resting places, flora, fauna, and people Frémont's and his party encountered on their journey west.

You’ve played the game Oregon Trail via DOS (as a child), online, or via app but have you traced the actual trail taken by John C. Frémont between 1842 and 1843? Now you can with this daily interactive map with journal.

Thanks Anelise Shrout!

App.net archive

App.net archive by Manton Reece(manton.org)
Linkrot and the lack of permanence on the web is a recurring theme for this blog. In the final days as App.net was winding down, I wanted to put my money where my mouth was. I spun up a couple new servers and wrote a set of scripts to essentially download every post on App.net. It feels like a fragile archive, put together hastily, but I believe it’s mostly complete. I’ve also downloaded thumbnail versions of some of the public photos hosted on App.net.

Interesting to see that Manton Reece created an impromptu archive of all of App.net before it shut down.​​

A reply to Kimberly Hirsch: Doing my part to fix the internet

Doing my part to fix the internet by Kimberly Hirsh
I have put all the tech in place that I need to, I think, for my publishing to happen here at kimberlyhirsh.com, go out to my various social places, and then have responses come back here.

Kimberly, Congratulations and welcome to the #indieweb! Interestingly, I’m seeing your post via Superfeedr piped into an IRC channel on freenode rather than webmention to my own site (since upgrading to the most recent version of Webmention for WordPress, I apparently need to re-enable exotic webmentions to my homepage).

I’m amazed that such a short comment that I wrote on my site back in November (and syndicated manually to another’s) should not only crop up again, but that it could have had such an influence. Further, the fact that there’s now a method by which communication on the internet can let me know that any of it happened really warms my heart to no end. As a counter example, I feel sad that without an explicit manual ping, Vicki Boykis is left out of the conversation of knowing how influential her words have been.

Kimberly, I’m curious to know how difficult you found it to set things up? A group of us would love to know so we can continue to make the process of enabling indieweb functionality on WordPress easier for others in the future. (Feel free to call, email, text, comment below, or, since you’re able to now, write back on your own website–whichever is most convenient for you. My contact information is easily discovered on my homepage.)

If it helps to make mobile use easier for you, you might find Sharing from the #IndieWeb on Mobile (Android) with Apps an interesting template to follow. Though it was written for a different CMS, you should be able to substitute WordPress specific URLs in their place:

You might also find some useful functionality hiding at WordPress Bookmarklets for Desktop if you haven’t come across it yet.

As someone who works in academic circles and whose “professional and personal interests are intertwined, I choose not to separate the two” on my site either, to help people more easily subscribe to subsets of data from my site more easily, I did a few things I’ve documented here: RSS Feeds. Additionally, choosing what gets syndicated to other sites like Twitter and Facebook rounds out the rest.

There are a number of other folks including myself using their sites essentially as commonplace books–something you may appreciate. Some of us are also pushing the envelope in areas like hightlights, annotationsmarginalia, archiving, etc. Many of these have topic pages at Indieweb.org along with examples you might find useful to emulate or extend if you’d like to explore, add, or extend those functionalities.

If you need help to get yourself logged into the indieweb wiki or finding ways to interact with the growing community of incredibly helpful and generous indeweb people, I am (and many others are) happy to help in any way we can. We’d love to hear your voice.

🔖 What is good mathematics? | Terry Tao

What is good mathematics? by Terence Tao(arxiv.org)
Some personal thoughts and opinions on what ``good quality mathematics'' is, and whether one should try to define this term rigorously. As a case study, the story of Szemer\'edi's theorem is presented.

This looks like a cool little paper.

Update 3/17/17

Some thoughts after reading

And indeed it was. The opening has lovely long (though possibly incomplete) list of aspects of good mathematics toward which mathematicians should strive. The second section contains an interesting example which looks at the history of a theorem and it’s effect on several different areas. To me most of the value is in thinking about the first several pages. I highly recommend this to all young budding mathematicians.

In particular, as a society, we need to be careful of early students in elementary and high school as well as college as the pedagogy of mathematics at these lower levels tends to weed out potential mathematicians of many of these stripes. Students often get discouraged from pursuing mathematics because it’s “too hard” often because they don’t have the right resources or support. These students, may in fact be those who add to the well-roundedness of the subject which help to push it forward.

I believe that this diverse and multifaceted nature of “good mathematics” is very healthy for mathematics as a whole, as it it allows us to pursue many different approaches to the subject, and exploit many different types of mathematical talent, towards our common goal of greater mathematical progress and understanding. While each one of the above attributes is generally accepted to be a desirable trait to have in mathematics, it can become detrimental to a field to pursue only one or two of them at the expense of all the others.

As I look at his list of scenarios, it also reminds me of how areas within the humanities can become quickly stymied. The trouble in some of those areas of study is that they’re not as rigorously underpinned, as systematic, or as brutally clear as mathematics can be, so the fact that they’ve become stuck may not be noticed until a dreadfully much later date. These facts also make it much easier and clearer in some of these fields to notice the true stars.

As a reminder for later, I’ll include these scenarios about research fields:

  • A field which becomes increasingly ornate and baroque, in which individual
    results are generalised and refined for their own sake, but the subject as a
    whole drifts aimlessly without any definite direction or sense of progress;
  • A field which becomes filled with many astounding conjectures, but with no
    hope of rigorous progress on any of them;
  • A field which now consists primarily of using ad hoc methods to solve a collection
    of unrelated problems, which have no unifying theme, connections, or purpose;
  • A field which has become overly dry and theoretical, continually recasting and
    unifying previous results in increasingly technical formal frameworks, but not
    generating any exciting new breakthroughs as a consequence; or
  • A field which reveres classical results, and continually presents shorter, simpler,
    and more elegant proofs of these results, but which does not generate any truly
    original and new results beyond the classical literature.

UCLA Mathematical Sciences Building

I’ll bet I had a better Pi Day than you did today. I got to sit through three hours of a fascinating lecture on complex analysis covering Bernoulli numbers, Reimann’s Zeta Function, the Gamma Function, Euler’s Function, the duplication formula, the symmetrical form of the zeta functional equation, and Reimann’s Hypothesis. All replete with references to pi! Take that nerds!

The best part of daylight savings time? I get to see the sun set on the Mathematical Sciences Building.

Study debunks old concept of how anesthesia works | Phys.Org

Study debunks old concept of how anesthesia works by Alyssa Sunkin-Strube(phys.org)
Anesthesia induces unconsciousness by changing the function of proteins that reside on the surface of a thin membrane that forms a barrier around all cells, according to new research from Weill Cornell Medicine scientists. The findings challenge a century-old concept of how anesthetics work and may help guide the development of new agents associated with fewer side effects.

🔖 How to Have a Good Day: Harness the Power of Behavioral Science to Transform Your Working Life by Caroline Webb

How to Have a Good Day: Harness the Power of Behavioral Science to Transform Your Working Life by Caroline Webb(Crown Business, February 2, 2016)
In How to Have a Good Day, economist and former McKinsey partner Caroline Webb shows readers how to use recent findings from behavioral economics, psychology, and neuroscience to transform our approach to everyday working life.

Advances in these behavioral sciences are giving us ever better understanding of how our brains work, why we make the choices we do, and what it takes for us to be at our best. But it has not always been easy to see how to apply these insights in the real world – until now.

In How to Have a Good Day, Webb explains exactly how to apply this science to our daily tasks and routines. She translates three big scientific ideas into step-by-step guidance that shows us how to set better priorities, make our time go further, ace every interaction, be our smartest selves, strengthen our personal impact, be resilient to setbacks, and boost our energy and enjoyment. Through it all, Webb teaches us how to navigate the typical challenges of modern workplaces—from conflict with colleagues to dull meetings and overflowing inboxes—with skill and ease.

Filled with stories of people who have used Webb’s insights to boost their job satisfaction and performance at work, How to Have a Good Day is the book so many people wanted when they finished Nudge, Blink and Thinking Fast and Slow and were looking for practical ways to apply this fascinating science to their own lives and careers.

A remarkable and much-needed book, How to Have a Good Day gives us the tools we need to have a lifetime of good days.

🔖 Pre-Suasion: A Revolutionary Way to Influence and Persuade by Robert Cialdini

Pre-Suasion: A Revolutionary Way to Influence and Persuade by Robert Cialdini(Simon & Schuster, September 6, 2016)
The author of the legendary bestseller Influence, social psychologist Robert Cialdini shines a light on effective persuasion and reveals that the secret doesn’t lie in the message itself, but in the key moment before that message is delivered.

What separates effective communicators from truly successful persuaders? Using the same combination of rigorous scientific research and accessibility that made his Influence an iconic bestseller, Robert Cialdini explains how to capitalize on the essential window of time before you deliver an important message. This “privileged moment for change” prepares people to be receptive to a message before they experience it. Optimal persuasion is achieved only through optimal pre-suasion. In other words, to change “minds” a pre-suader must also change “states of mind.”

His first solo work in over thirty years, Cialdini’s Pre-Suasion draws on his extensive experience as the most cited social psychologist of our time and explains the techniques a person should implement to become a master persuader. Altering a listener’s attitudes, beliefs, or experiences isn’t necessary, says Cialdini—all that’s required is for a communicator to redirect the audience’s focus of attention before a relevant action.

From studies on advertising imagery to treating opiate addiction, from the annual letters of Berkshire Hathaway to the annals of history, Cialdini draws on an array of studies and narratives to outline the specific techniques you can use on online marketing campaigns and even effective wartime propaganda. He illustrates how the artful diversion of attention leads to successful pre-suasion and gets your targeted audience primed and ready to say, “Yes.”

🔖 Confessions of the Pricing Man: How Price Affects Everything by Hermann Simon

Confessions of the Pricing Man: How Price Affects Everything by Hermann Simon(Springer, 2015)
The world’s foremost expert on pricing strategy shows how this mysterious process works and how to maximize value through pricing to company and customer.

In all walks of life, we constantly make decisions about whether something is worth our money or our time, or try to convince others to part with their money or their time. Price is the place where value and money meet. From the global release of the latest electronic gadget to the bewildering gyrations of oil futures to markdowns at the bargain store, price is the most powerful and pervasive economic force in our day-to-day lives and one of the least understood.

The recipe for successful pricing often sounds like an exotic cocktail, with equal parts psychology, economics, strategy, tools and incentives stirred up together, usually with just enough math to sour the taste. That leads managers to water down the drink with hunches and rules of thumb, or leave out the parts with which they don’t feel comfortable. While this makes for a sweeter drink, it often lacks the punch to have an impact on the customer or on the business.

It doesn’t have to be that way, though, as Hermann Simon illustrates through dozens of stories collected over four decades in the trenches and behind the scenes. A world-renowned speaker on pricing and a trusted advisor to Fortune 500 executives, Simon’s lifelong journey has taken him from rural farmers’ markets, to a distinguished academic career, to a long second career as an entrepreneur and management consultant to companies large and small throughout the world. Along the way, he has learned from Nobel Prize winners and leading management gurus, and helped countless managers and executives use pricing as a way to create new markets, grow their businesses and gain a sustained competitive advantage. He also learned some tough personal lessons about value, how people perceive it, and how people profit from it.

In this engaging and practical narrative, Simon leaves nothing out of the pricing cocktail, but still makes it go down smoothly and leaves you wanting to learn more and do more―as a consumer or as a business person. You will never look at pricing the same way again.
