The Springer created this short quiz (Which Springer GTM would you be?) for you to identify which math book you would be. I am Intro to Knot Theory. I don’t know what to say… If I were a Springer-Verlag Graduate Text in Mathematics, I would be W.B.R. Lickorish’s An Introduction to Knot Theory I am… Read More Which mathematical book are you?

After a little search I have found how to convert .dta from stata 13 to be used in stata 10-12. Note that if you are using stata 10.0 you will need first to update to stata 10.1 by runing “update all”. The update is free. You need to use command called use13 written by Sergiy… Read More Convert dta to stata 10-12

In general, I prefer to use the plot functions that comes in the basic packages in R to plot and display data. However, ggplot and lattice can be very handy for some tasks. I was visiting randomly some webpages on the internet this days and I came accross this blog. It compares lattice and ggplot.… Read More Comparing lattice and ggplot

Academic life and knowledge “you are not engaged so much in acquiring knowledge as in making mental efforts under criticism. A certain amount of knowledge you can indeed with average faculties acquire so as to retain; nor need you regret the hours that you have spent on much that is forgotten, for the shadow of… Read More Quotes

This is an example of how to plot GIS data using R. In this example, I will plot a map of Brazilian municipalities and the color of each city in the maps will be mapped to its GDP, proportion of votes of the winner president in the 2014 election, and proportion of families receiving the… Read More Plotting maps using R (example with Brazilian Municipal level data)

The title of the post is the title of an article written by Eugene Wigner in 1960 (you can find it here). I remember that article when I watched interestellar. I am amazed with the power of that artificial language that we call mathematics, its axiomatic method, the formal logic and the theory that lies… Read More The unreasonable effectiveness of mathematics in the natural sciences
