Tangential and radial components of acceleration using complex numbers

-

 If unit vectors always scared you for some reason, this neat little trick  from The story of i by Paul Nahin involving complex numbers is bound to be a solace.

It allows you find the tangential and radial components of acceleration through simple differentiation. How about that! 

r = r(t),  θ =  θ(t)

  Imagine if mathematicians were tasked with with teaching Cinderella you know you could imagine that we just say theorem -- Cinderella lived happily ever after every be done with it  you know and that totally misses the point. I mean nobody cares about the happily ever after you know they care about the story. Checkout Jim Fowler's courses on YouTube . They are truly one of a kind.  -- The humanity of calculus | Jim Fowler | TEDxColumbus

Communicating and downloading data from the James Webb Space Telescope

-
We use the DSN ([Deep Space Network](https://www.jpl.nasa.gov/missions/dsn)) to communicate with the observatory. We receive data when we have a contact with Webb using a DSN antenna The DSN has three sites around the world, each positioned 120 degrees apart. There are antennas in Goldstone, California; Canberra, Australia; and Madrid, Spain. This allows us to communicate with Webb at any time of day Each of the [DSN complexes](https://www.nasa.gov/directorates/heo/scan/services/networks/deep_space_network/complexes) has different types of antennas, including 70-meter (230-foot in diameter), 34-meter (111-foot in diameter), and 26-meter (85-foot in diameter) antennas. The DSN complexes use the 34-meter antennas to talk with Webb with the 70-meter antennas as a backup. The DSN supports different radio frequency allocations, such as the S-band and Ka-band frequencies that Webb uses. -band has a lower bandwidth, and we use that to send commands to the spacecraft (e.g., start recorder play...

beautifyPlot: A simple matplotlib wrapper to avoid writing ‘plt.’ statements on many lines

-
I made a wrapper to avoid writing ‘plt.’ statements on many lines. This method also lets me save the arguments passed to matplotlib in a file for later use. GitHub repo: https://github.com/kvgc/beautifyPlot Example: matplotlib code: import numpy as np import matplotlib . pyplot as plt x = np . arange ( 0 , 100 , 1 ) y = x ** 3 plt . plot ( x , y , label = 'y=f(x)' ) plt . title ( "test plot" ) plt . xlim ([ 0 , 10 ]) plt . ylim ([ 0 , 1000 ]) plt . legend ( fontsize = 15 ) plt . tight_layout ()   Using beautifyPlot module: from beautifyPlot . bplt import beautifyPlot import numpy as np x = np . arange ( 0 , 100 , 1 ) y = x ** 3 plt . plot ( x , y , label = 'y=f(x)' ) plotArgs = { 'title' : [ 'test plot' ], ## Use list to pass a set of arguments to the function 'xlim' : [ 0 , 10 ], 'ylim' : [ 0 , 1000 ], 'legend' : { ...
