Water is Diamagnetic: A simple experiment

-

Since water is diamagnetic(they are slightly repelled by magnetic fields ) when one brings a strong Neodymium magnet near its surface, it makes a slight dent on it.

In this video this is visualized by placing a striped pattern as the background. Without a magnet, the water surface is calm and the striped pattern appears as is.

But when a magnetic field is introduced, the water surface is no longer flat and  changes the way the light gets reflected off it.

 



 


 

An analogy


 

If you have had a dent on your car, then you might be able to relate to this phenomenon. Before the dent, the surface was smooth and  the car looked great, but after the dent light reflecting off it just makes the dent look more prominent.  

In our case we are making a forcibly making a dent in order to prove that the water is diamagnetic using a powerful magnet. The light reflecting off it just makes this dent look prominent.

  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' : { ...
