Data Analysis of Gender in Film Dialog

The data set used in this analysis would be really cool to explore (perhaps in combination with movie networks).

The Onion Wins Again: Roger Ailes Edition

The Onion wins yet again! This one is really funny.

An Excellent Straw Man

This SMBC is awesome! I am highly amused.

This may be my favorite ever straw man.

Blessing Computers with Holy Water

On Facebook, Jean Bellissard shared the following rather amusing article. Besides laughing, an immediate thing to do was to do a Google search and see if this was fake. That led me to this article, which notes among other things that a picture being circulated widely now is from 2013. However, the following quote also appears in the article:

"Apparently, it’s a common practice in Russia for Orthodox priests to bless server rooms and other technology equipment. So, it won’t be wrong to assume that priests might be really called in upcoming days to bless the computers once again. I just hope that priests would be careful enough to not get the water inside the PCs; I’m sure that computer suppliers won’t be enthusiastic to replace damage due to water."

I am amused.

Also, our printers could use some holy water.

Map of Literature's Epic American Road Trips

This visualization of epic American road trips from literature is very cool!

You have walks on networks, you have different ones that you can compare to each other, and you also have descriptions from the authors of these different places.

A Big Pile of ... Linear Algebra

That's right. In many cases, machine learning is a big pile of ... linear algebra.

"Quasi-Centralized Limit Order Books"

One of my papers got assigned its final journal coordinates today. (It came out a few months ago in advanced access.) Here are the details.

Title: Quasi-Centralized Limit Order Books

Authors: Martin D. Gould, Mason A. Porter, and Sam D. Howison

Abstract: A quasi-centralized limit order book (QCLOB) is a limit order book (LOB) in which financial institutions can only access the trading opportunities offered by counterpartieswithwhomthey possess sufficient bilateral credit. In this paper, we perform an empirical analysis of a recent, high-quality data set from a large electronic trading platform that utilizes QCLOBs to facilitate trade. We argue that the quote-relative framework often used to study other LOBs is not a sensible reference frame for QCLOBs, so we instead introduce an alternative, trade-relative framework, which we use to study the statistical properties of order flow and LOB state in our data. We also uncover an empirical universality: although the distributions that describe order flow and LOB state vary considerably across days, a simple, linear rescaling causes them to collapse onto a single curve. Motivated by this finding, we propose a semi-parametric model of order flow and LOB state for a single trading day. Our model provides similar performance to that of parametric curve-fitting techniques but is simpler to compute and faster to implement.

Why I Joined the American Physical Society

The American Physical Society (APS) e-mailed its 2016 Fellows to ask them to write a sentence or two about why they joined the APS.

They wrote: "If you can tell us in a sentence or two why you chose to be a member of APS, and we use your quote in the APS membership brochure, we will send you one item of your choice from the APS store."

Here is what I decided to write: I chose to join APS because my research as an applied mathematician also interfaces with numerous areas of physics (and I publish much of my work in physics journals), and I wanted to make sure that I am also part of the physics community. I was already playing ultimate frisbee with physicists in grad school, and this was the natural next step.

Do you think they'll use my quote?

Patent Application (from 2012): "Devices and Implements for Deterring Monsters, Specters, Demons, and the Like"

This patent application, filed in 2012, is called "Devices and implements for deterring monsters, specters, demons, and the like".

Here is a choice excerpt: Devices and implements for staving off monsters, specters, demons and the like as imagined by a child at bedtime. A hand-held controller unit is provided having a user interface, which is capable of being used by the child under the bed covers of a bed. The hand-held controller unit may include any of a walkie-talkie capability, a flashlight capability, a nightlight capability, the capability to activate an external device, and other capabilities. At least one external device may be provided which is capable of being placed beneath the bed and is configured to be activated by the hand-held controller unit. At least one substantially hollow air-through member may be provided which is configured to facilitate airflow between underneath the bed covers of the bed and above the bed covers of the bed. A supplemental bed cover may be provided that is configured to be placed on the bed.

Personally, I am most afraid of "the like".

Also, the Google Patent listing says the patent was granted.

Museum Notice of the Day

Wow! This is spectacular!

Congratulations to Sandy Patel!

Support staff member Sandy Patel of University of Oxford's Mathematical Institute won the Oxford University Students Union award for best support staff. Congratulations!

Credit where it is due on two counts:

(1) Sandy is a very good member of support staff! I have interacted with support staff at many places, and good ones versus bad ones make a huge difference in academic experience. Sandy always stood out during my time at Oxford as one of the really good ones. The number of times I have told my students to 'Go ask Sandy Patel." (and similar) is very numerous indeed.

(2) And credit to my former employer (the Oxford Mathematical Institute) for publishing Sandy's award on their website and circulating it on Twitter. This type of recognition is almost always in the background and it shouldn't be. (I learned this from grad school, where we had the awesome Dolores Pendell, versus nearly everywhere else I have been.) We spend a lot of time bragging about the scientific accomplishments of faculty (and occasionally also their teaching accomplishments, though not enough), but we almost never publicize things when our support staff are excellent (though we do complain loudly when they're not), and we should!

Classic Typewriter Exhibit at San Fransisco International Airport

This is really cool!

The typewriter in the picture below is part of a current exhibit in terminal 2 of SFO airport.



Among the things I enjoyed when on sabbatical at Stanford were the really cool exhibitions at SFO. Among other things, this included one of classic boardgames.

Harry McCracken also posted pictures of several other typewriters from the exhibit on his Twitter feed. Take a look at this one, this one, this one, this one, and this one. This should be all of the typewriter pictures that he posted as part of this thread.
