Visualizing Covid-19 cases in San Diego by zip code using Bokeh

Energy band diagrams are used to visulize the electron and hole transport in Solar cells and LED research. I want to quickly draw them and came up with a python module.

Here's an example on how to use this code.

Found two ways to do it. Thanks to stack overflow posts.

Method 1 (as mentioned here):

This is …

Coupled dipole approximation (CDA) method is a numerical method to calculate the optical properties (scattering and absorption) of interacting dipoles. This method is used in discrete dipole approximation method (like in DDSCAT software), where a big particle (also known as target) is broken into lot of interacting dipoles arranged in …

Sometimes you have to show positive, zero and negative number in log scale. However you cannot take log of negative numbers and zero. But one could approximate it with a log transform modulus as stated here.

I keep needing a python code to generate the dielectric functions of plasmonic materials such as Au, Ag, Pd, and Pt. So I wrote a python version of LD.m.

LD.m is a matlab file written by Bora Ung that produces dielectric functions of metals either for Lortenz and …

DC power supplies are very handy for electronic projects. They help to apply bias/voltage to a device. Controlling it by a computer by a program is helpful in advanced projects where timing and accurate control is an issue.

I got my hands on a RIGOL DP832 which is three …

I have been interested in monitoring and keep track of my weight. In the past, I have used different phone apps to track my weight. They work reasonably well, but I was thinking of reading weight data directly from my weighing scale and upload the data to an online database …

I am playing with Python for the first time. The syntax seems to be so natural. So many modules (numpy, scipy and matplotlib) for researchers/scientists. Cannot see any shortcoming at this point. Perhaps need more testing and implementation.
