So I decided to wear my favorite pink dress (Malala Yousafzai) After reading the diary of a Pakistani schoolgirl and Malala’s history, there is no doubt of being in front […]Two model theory meetingshttp://www.mathblogging.org/post/1018812014-10-20T01:15:47-04:00andrescaicedoJosé Iovino has asked me to help advertise the following: At the 2015 Joint mathematics meetings (JMM), January 10-13, in San Antonio, TX, there will be two special sessions on model theory. The first is Beyond First Order Model Theory, a special session of the ASL and the AMS.

I think the easiest answer is to have kids using the laptops for watching videos, looking upThe myth of a data-driven Netflixhttp://www.mathblogging.org/post/1018792014-10-20T00:30:00-04:00MarkThere's been a lot of talk about Netflix stock this week (usually with words like "plummet"), but a big part of the story has largely gone unnoticed, probably in part because it involves statistics.<br /><br />As mentioned before, some aspects of the Netflix narrative such as the company building and HBO type content library, are simply, factually incorrect. Others, while not blatantly wrong, are difficult to reconcile with the facts.<br /><br />One of the accepted truths of the Netflix narrative is that CEO Reed […]Sudoku Matroids and Graph Colouring Verificationhttp://www.mathblogging.org/post/1018872014-10-20T00:01:11-04:00Tony HuynhAs this is my first post, I feel obliged to say the obligatory Hello World!.

Can you distinguish the scientific from the non-scientific or the pseudoscientific? If you can then how?

The idea is to generate forecasts for all series at all levels of aggregation without imposing the aggregation constraints, and then to reconcile the forecasts so they satisfy the aggregation constraints. (An introduction to reconciling hierarchical and grouped time series is […]Launching Free Live Chat Supporthttp://www.mathblogging.org/post/1018702014-10-19T21:55:42-04:00Dan langToday!

Here is some useful information that I’ve created about the basics of trigonometry as well as the graphs. Part 2 is out. You can find it here.
All graphs come from Wolfram Alpha (very cool resource).<br/>
Degrees & Radians; Six Trig Functions
Coterminal Angles, Arc Length, and Signs
The All Important Unit Circle (sorry, it’s a bit hard to see)
Those Pesky Trig Graphs
I have to know more graphs???
I hope this has helped you get closer to being a master at trig. More

No, it's really sad. <br /><br />I started Fall Break with grand plans. I was going to tackle my to do list. I was going to catch up in life. Oh, life happened. That's for sure. But, I'm not sure I feel any more ahead than I did five days ago. <br /><br />I marked a few things off of my to do list. I read a book on approaching life with bravery and courage. And, I did some things that I wouldn't have had the courage to do a year ago or […]Discount and Percentagehttp://www.mathblogging.org/post/1018672014-10-19T20:42:56-04:00Dan langIn this article, you will be able to practice problems about discounts and percentage.

Are the learning targets clear and explicit? What are important check points and questions to guide the community to know if learning is occurring? Is there a plan for actions needed when we learn we must pivot?

rate of changehttp://www.mathblogging.org/post/1018542014-10-19T18:22:45-04:00rdkpickleI’ve been a bit worried, lately, that resolved anxiety has led to mild amounts of complacency and boredom. The issue is not that I am under any kind of delusion that I have no more growing to do as a teacher. (Please.) It’s that – absent the novice teacher’s quest for a comfortable teaching identity, the sizable […]Shravan Vasishth at Bayes in Paris this weekhttp://www.mathblogging.org/post/1018532014-10-19T18:14:25-04:00xi'anTaking advantage of his visit to Paris this month, Shravan Vasishth, from University of Postdam, Germany, will give a talk at 10.30am, next Friday, October 24, at ENSAE on: Using Bayesian Linear Mixed Models in Psycholinguistics: Some open issues With the arrival of the probabilistic programming language Stan (and JAGS), it has become relatively easy […]Reflective writing in mathhttp://www.mathblogging.org/post/1018562014-10-19T17:51:06-04:00Mary DoomsSomehow there’s a disconnect between my writing expectations in math and what’s being turned in.
