#RandomExperimentSundays : I was curious if char-rnn (https://github.com/karpathy/char-rnn) can generate new, fun and plausible baby names. So I got a dataset of 8,000 baby names from an NLP repo (http://www.cs.cmu.edu/afs/cs/project/ai-repository/ai/areas/nlp/corpora/names/), trained a 2-layer LSTM and generated some.

To my amusement many fun unique names come out and 90% of them are not found in the training data. Here are 100 example samples that do not occur in training data:

Rudi

Levette

Berice

Lussa

Hany

Mareanne

Chrestina

Carissy

Marylen

Hammine

Janye

Marlise

Jacacrie

Hendred

Romand

Charienna

Here is a much bigger sample: http://cs.stanford.edu/people/karpathy/namesGenUnique.txt

Some of my favorites include "Baby" (haha), "Killie", "Char", "R", "More", "Mars", "Hi", "Saddie", "With" and "Ahbort". Well that was fun.

This is what I mainly been working on over the last year and a half.

**Pixar in a Box - Explore The Math & Science Behind Pixar's Film in These Exciting Online Courses For Kids, Teens & The Curious-Minded**

Pixar, in partnership with Khan Academy, have launched an exciting educational program geared towards kids and teens (or the curious-minded) to learn about the math and science that helps bring their films to life called, Pixar in a Box . The series of free...

A rope is supported at its ends. What shape do you think it assumes? Galileo though parabola, in red. Wrong! The right answer, so called catenary, is very close.

The curve described by a uniform chain hanging from two supports in a uniform gravitational field is called a catenary, a name apparently coined by Thomas Jefferson. If the sag is mall, so that the weight is about uniformly distributed, the curve is close to a parabola, a quadratic curve, but the catenary is a hyperbolic cosine curve, y = a cosh(x/a), where x is measured from the lowest point. The tension in the chain increases from that at the lowest point toward the points of support. Because all the load is vertical, the horizontal component of the tension is constant. A uniform cable also hangs in a catenary; the essential thing is that there is negligible transverse stiffness.

The curve can be inverted to form an arch, in which the tension becomes a compression, least at the highest point and increasing downward. If the arch is uniform, the compressive stress will follow the catenary curve and there will be no tendency to buckle. If the load is horizontally uniform, the curve will be a parabola. The St. Louis Gateway Arch is an example. Since the arch is smaller in cross section at the top, the curve is a flattened catenary.

When I first saw Ad Reinhardt's picture I thought it was another ridiculous modern art piece, but I was won over by the description of how it was made in this video:

I made my own tribute to it (which can be made easier to see) here:
