Tell me, which side of the earth does this nose come from? Ha! (ALF) Reading about strange attractors I came across with this book, where I discovered a way to generate two dimensional chaotic maps. The generic equation is pretty simple: I used it to generate these chaotic galaxies: Changing ...

La luna sale a caminar siguiendo tus pupilas (Ojos color sol, Calle 13) This is a 5×5 1-matrix: And this is a 20×20 1-matrix visualized: Maybe in some other galaxy, aliens represent matrix in this way.

Just keep swimming (Dory in Finding Nemo) Inspired by this post, I decided to create gummy worms like this: Or these: When I was young I used to eat them. Do you want to try? This is the code:

I said, “Wait a minute, Chester, you know I’m a peaceful man”, He said, “That’s okay, boy, won’t you feed him when you can” (The Weight, The Band) It is quite easy to calculate the probability of obtaining the same number of heads and tails when tossing ...

If there is a God, he’s a great mathematician (Paul Dirac) Imagine you toss a coin 12 times and you count how many heads and tails you are obtaining after each throwing (the coin is equilibrated so the probability of head or tail is the same). At some point, it ...

I believe in the truth of fairy-tales more than I believe in the truth in the newspaper (Lotte Reiniger) In my opinion, this graph is a visual demonstration that we live in a male very chauvinist world. In this experiment I download the members of ten top orchestras of the ...

In the whole history of the world there is but one thing that money can not buy… to wit the wag of a dog’s tail (Josh Billings) In this post I combine several things: Simple webscraping to read the list of companion dogs from Wikipedia. I love rvest package ...

The world is full of wonderful things, like sunflowers (Machanguito, my islander friend) Sunflower seeds are arranged following a mathematical pattern where golden ratio plays a starring role. There are tons of web sites explaining this amazing fact. In general, the arrangement of leaves on a plant stem are ruled ...

It is a capital mistake to theorize before one has data (Sherlock Holmes, A Scandal in Bohemia) One of my favorite entertainments is drawing things: crazy curves, imaginary flowers, celestial bodies, fractalic acacias … but sometimes I wonder myself if these drawings result interesting to whom arrive to my blog. One ...

When I grow up I want to be a dancer (Carmen, my beautiful daughter) The presence of women in positions of responsibility inside Big Data companies is quite far of parity: while approximately 5o% of world population are women, only 7% of CEOs of Top 100 Big Data Companies are. Like it ...

So rock me mama like a wagon wheel, rock me mama anyway you feel (Wagon Wheel, Old Crow Medicine Show) This is the third iteration of Hilbert curve. I placed points in its corners. Since the curve has beginning and ending, I labeled each vertex with the order it occupies:...

It seemed that everything is in ruins, and that all the basic mathematical concepts have lost their meaning (Naum Vilenkin, Russian mathematician, regarding to the discovery of Peano’s curve) Giuseppe Peano found in 1890 a way to draw a curve in the plane that filled the entire space: just a ...

I am an absolute beginner, but I am absolutely sane (Absolute Beginners, David Bowie) Some time ago I wrote this post, where I predicted correctly the winner of the Spanish Football League several months before its ending.

Mmm. Lost a planet, Master Obi-Wan has. How embarrassing (Yoda, Attack Of The Clones) Some time ago I published this post in KDnuggets in which I analyze historical temperatures to show how we are gradually heading toward a warmer planet. Simple data science to obtain a simple (and increasingly accepted) ...

Antonio, you don’t know what empathy is! (Cecilia, my beautiful wife) Spirals are nice. In the wake of my previous post I have done a Shiny app to explore patterns generated by changing angle, shape and number of points of Fermat’s spiral equation. You can obtain an almost ...
