Four good women

Alexandra Ocasio-Cortez, Rashida Tlaib, Ayanna Pressley, and Ilhan Omar stand in human history as the four good representatives in the U.S. Congress.

AOC and her colleagues traveled to the border and saw firsthand the cruel and unsanitary conditions people were being held in ICE Detention Centers near the U.S.-Mexican border.

No clean clothes. Insufficient food. No soap, diapers, or toothbrushes.

If you’re gonna build a wall, be prepared for the day it falls.

Lesson #9: Major Chord Variations

Here are some major chord variations, given that these are real Root 5/6 shaped chord variations:

Root 5 E-shaped Major chord variations

Root 6 A-shaped Major chord variations

Root 6 D-shaped Major chord variations

Root 5 D-shaped Major chord variations

Root 6 B-shaped Major chord variations

Root 5 B-shaped Major chord variations

Root 6 E-shaped Major chord variations

Mathematics #8: Radio

On June 15th 2019 I completed my work in Mathematics Research with a very naïve claim that GNOME Internet Radio Locator beats Turing’s test in Artificial Intelligence with a Gettier counter-example argument, since there is no way to know if the radio streaming is broadcasting recorded or live.

My conclusion: The only way to gain new recommendations from a human being is to meet new people, expand your Social Graph, like I wrote in or listen to radio for new ideas.

I choose to meet new people.

Mathematics #7: Haversine

In August 2015 I went to Berkeley, California and wrote a paper on a new web site called Piperpal. You can read about my work on the web site at

Given two geographical coordinates P(glat,glon) and Q(latpoint,longpoint), you can calculate the distance r between P and Q in meters with the following Haversine formula:

111.045*DEGREES(ACOS(COS(RADIANS(latpoint))COS(RADIANS(glat))COS(RADIANS(longpoint)-RA DIANS(glon))+SIN(RADIANS(latpoint))SIN(RADIANS(glat))))

Check with other sources before you implement Haversine distance in your computer program.
