Here is a beautiful website by Grant Sanderson. 3blue1brown So many exciting insightful mathematics presentations. The craft and artistry are as impressive as the mathematical concepts. Take a look — even if you think you know the material — you will see a few new gems (I bet).

Raspberry Pi with Sunfounder Sensor Kit
The video shows the LCD Display connected to the Raspberry Pi. Easy setup Easy programming
What’s on the Pythonista menu? Yep, sliders! Side dish of booleans, integers and floats
I built this app and am running this app on my iPad. Credit to: mikaelho / pythonista – gestures tdamdouni / Pythonista Pythonista / slider / SliderWithLabel_danrcook.py The video shows an app with 8 inputs — 2 integer, 4 float, 2 boolean. Numeric input is tedious — at best; slider input is easier and offers positive feedback. In this […]

ASCE 7-16 Ice Loading using Pythonista 10/2018
The Pythonista UI makes development easy — almost fun See video link. I built this app and am running this app on my iPhone. I also built a version for my iPad — simple to accommodate. User can: Filter and select from ~2000 standard AISC shapes Calculate ice weight for any type of AISC shape at […]
AISC C Coefficient for Bolt Groups using Azure Jupyter Notebook 10/2018
I decided to try out Jupyter using Microsoft Azure (currently free). I’ve invested a couple days on this project including learning new notebook extensions and Interact widgets. And so far, so good. Pros Easy to use Well-documented Relatively trouble-free Cons Could have faster response times

get_next, get_prev, in Python OrderedDict 08/2018
I provide an example class based on an OrderedDict — with an adjunct dictionary to index to the next and prev OrderedDict entry. In my case, I have a rather static OrderedDict: it is a dictionary of AISC shape objects. The function set_prev_next() must be called after each operation that modifies OrderedDict. class MyClass(coll.OrderedDict): mynpdict […]
A single star orbiting the black hole in the center of the Milky Way 07/2018
https://www.sciencenews.org/article/star-orbiting-black-hole-einstein-gravity-general-relativity In a paper published July 26 in Astronomy & Astrophysics, a team of researchers reports the observation of a hallmark of general relativity known as gravitational redshift. The measurement is the first time general relativity has been confirmed in the region near a supermassive black hole. As light escapes a region with a strong gravitational field, […]
