Inventor of the World's Fastest Computer

Dr. Philip Emeagwali, who has been called the "Bill Gates of Africa," was born in Nigeria in 1954. Like many African schoolchildren, he dropped out of school at age 14 because his father could not continue paying his school fees. However, his father continued teaching him at home, and every day, Emeagwali performed mental exercises such as solving 100 math problems in one hour. His father taught him until Philip "knew more than he did."

Growing up in a country torn by civil war, Emeagwali lived in a building crumbled by rocket shells. He believed his intellect was a way out of the line of fire, so he studied hard and eventually received a scholarship to Oregon State University when he was 17, where he obtained a BS in mathematics. He also earned three other degrees—a Ph.D. in scientific computing from the University of Michigan and two Master's degrees from George Washington University.

The noted black inventor received acclaim based, at least in part, on his study of nature, specifically bees. Emeagwali saw an inherent efficiency in the way bees construct and work with honeycombs and determined computers that emulate this process could be the most efficient and powerful. In 1989, emulating the bees' honeycomb construction, Emeagwali used 65,000 processors to invent the world's fastest computer, which performs computations at 3.1 billion calculations per second.

Dr. Philip Emeagwali's resume is loaded with many other such feats, including ways of making oil fields more productive – which has resulted in the United States saving hundreds of millions of dollars each year. As one of the most famous African-American inventors of the 20th century, Dr. Emeagwali also won the Gordon Bell Prize – the Nobel Prize for computation. His computers are currently being used to forecast the weather and to predict the likelihood and effects of future global warming.

The 'Green Book' Was a Travel Guide Just for Black Motorists, Danielle Moodie-Mills, NBCBLK, October 11, 2016

The meaning of SANKOFA, Sankofa.org/about

Happy Black History Month (tomorrow), for what it's worth at the moment.

The Green Book: Guide to Freedom is a documentary about the emergence of the Black middle class in the 1940s and 1950s. The documentary explores the dangerous journeys Black people took outside their cities and the book that helped guide them.

The book, The Negro Motorist Green Book, was a guide for Black people to find places to eat, drink, shop, and stay overnight. The book was no longer needed after the Civil Rights Act of 1964 outlawed the racial discrimination that made it necessary. Google AI

The Google AI stated that it's "not available on Hulu," which was news to me, as I had just watched it on Hulu (probably because I saved it in my "favorites" and the Hulu streaming gods left me alone - they get paid monthly).

The Negro Motorist Green Book, popularly known as the Green Book, was a travel guide intended to help African American motorists avoid social obstacles prevalent during the period of racial segregation, commonly referred to as Jim Crow.  The Green Book listed businesses that would accept African American customers.

The book was the vision of Victor Green, an African American US postal employee from Harlem, New York.  The first guide focused on Metropolitan New York.  The next year, in 1937, Green expanded listings to other locations.  His book would eventually include every state and several international destinations before ceasing publication in 1964.  Before its demise, the book was the most popular of several tourist guides created specifically for an African American audience.

These types of travel guides were necessary during the Jim Crow era because African Americans were subject to acts of discrimination and occasional intimidation as many businesses refused to accept them as customers.  African American motorists, for example, were warned to avoid sundown towns which required minorities to be outside the city limits before sundown, hence the name.  African American travel could be fraught with risk and guides like the Green Book were an important resource.

One of the unintended consequences of the success of the Civil Rights Movement is a lot of businesses that sprang up in reaction to segregation now had to compete with larger corporations during "integration" that could offer more services. Many businesses that advertised in the Green Book no longer exist, boarded up, and condemned, many are not even memorialized with a historical designation in the cities they were located. The FW Woolworth International Civil Rights Museum is a noted exception and the Magnolia House (listed in The Green Book), both in Greensboro, North Carolina.

Tabitha Brown and Melissa Butler have sounded the alarm on the unintended consequences of boycotting businesses that have removed their DEI initiatives. Like the black-owned businesses post-Green Book, they might not survive, and it took years to get their products placed in the "big box" stores. Their sales dropping would mean they would be removed from the shelves they fought so long to occupy, in favor of the products the corporation would promote over theirs. Again, going into spaces that took considerable effort to sell products in gives our (as of 2019) 910 billion dollars, projected to be 1.7 trillion in 2030 consumer impact, it would seem that we lack both focus and vision: that buying power impacts Target and similar businesses giving our dollars on the altar of corporate indifference. We seem to justify finding our own backdoors.

“If you can control a man's thinking you do not have to worry about his action. When you determine what a man shall think you do not have to concern yourself about what he will do. If you make a man feel that he is inferior, you do not have to compel him to accept an inferior status, for he will seek it himself. If you make a man think that he is justly an outcast, you do not have to order him to the back door. He will go without being told; and if there is no back door, his very nature will demand one.”
― Carter Godwin Woodson, The Mis-Education of the Negro

"Who taught you to hate yourself? Who taught you to hate the color of your skin? To such an extent you bleach, to get like the white man. Who taught you to hate the shape of your nose and the shape of your lips? Who taught you to hate yourself from the top of your head to the soles of your feet? Who taught you to hate your own kind? Who taught you to hate the race that you belong to so much so that you don't want to be around each other?"

Who Taught You to Hate Yourself? Malcolm X, May 5, 1962, Genius dot com

Sixty-three years ago, Malcolm called the motives of the Antioch High School shooter. He posted anti-black, antisemitic tropes online. Who taught him to hate himself?

Boycotts are the knee-jerk, go-to tactic we gravitate to without an understanding of the mathematics of the Montgomery Bus Boycott: 30,000 - 40,000 African Americans participated, 90% of the black residents participated, and they comprised 75% of the bus company's customers. Therefore, unless the clientele of Target and Walmart match Montgomery's numbers, any thought of a boycott will only hurt these black businesses.

The irony of these dark times is this blatant white supremacy should drive us closer together. In our 0.9 to 1.7 trillion dollar demographic, only two cents gets to the African American community:

An NAACP study found that a dollar circulates in Asian communities for 30 days, as opposed to six hours in Black communities. It found that only two cents of every dollar African Americans spend goes to Black-owned businesses. One researcher estimated that if Black consumers spent at least one dollar out of every ten with Black businesses, it could generate one million jobs for African Americans. Minority buying power can do far more than purchase; it can become an investment in stronger, local communities.

One dollar out of every ten is ten cents per dollar of the 0.9 to eventually 1.7 trillion dollars we freely give to this economy for continued disrespect, disheartening policy decisions, and abject hatred of our contributions to this nation. A tithe, and we don't have to ask anyone's permission to do so. This cooperation is beyond reflexive boycotts without clear goals and the will to be uncomfortable for long terms: the Montgomery boycott lasted over a year.

Wakanda and its superhero ruler, T'Challa/The Black Panther, is a fantasy comic book product (the first black superhero) developed by Stan Lee and Jack Kirby, for Marvel.

Mansa Musa ruled the Mali Empire, and unlike the fictional wealth of the nonexistent element, Vibranium, his wealth was from the conventional element of gold and the mineral salt. He was said to have been the richest person who has ever lived.

This present darkness may be the thing we need to come together again. Ten cents won't get us the Mali Empire, or Wakanda, but it might get us independence, freedom, a sense of control of our own destinies, and peace of mind. It will be as long, or longer than a boycott, but we would have to work together towards a common goal. It would be the last thing they would expect us to do. The dominant society is counting on it that we won't. We will also have to be willing to literally fight for it because as history has shown in Tulsa, Oklahoma, and Rosewood, Florida, success attracts the jealousy of psychopaths.

For thousands of years, ancient societies all around the world erected massive stone circles, aligning them with the sun and stars to mark the seasons. These early calendars foretold the coming of spring, summer, fall, and winter, helping civilizations track when to plant and harvest crops. They also served as ceremonial sites, both for celebration and sacrifice.

These megaliths — large, prehistoric monuments made of stone — may seem mysterious in our modern era, when many people lack a connection with, or even view of, the stars. Some even hold them up as supernatural or divined by aliens. But many ancient societies kept time by tracking which constellations rose at sunset, like reading a giant, celestial clock. And others pinpointed the sun’s location in the sky on the summer and winter solstice, the longest and shortest days of the year, or the spring and fall equinox.

Europe alone holds some 35,000 megaliths, including many astronomically-aligned stone circles, as well as tombs (or cromlechs) and other standing stones. These structures were mostly built between 6,500 and 4,500 years ago, largely along the Atlantic and Mediterranean coasts.

The most famous of these sites is Stonehenge, a monument in England that’s thought to be around 5,000 years old. Though still old, at that age, Stonehenge may have been one of the youngest such stone structures to be built in Europe.

The chronology and extreme similarities between these widespread European sites lead some researchers to think the regional tradition of constructing megaliths first emerged along the coast of France. It was then passed across the region, eventually reaching Great Britain.

But even these primitive sites are at least centuries younger than the world’s oldest known stone circle: Nabta Playa.

Located in Africa, Nabta Playa stands some 700 miles south of the Great Pyramid of Giza in Egypt. It was built more than 7,000 years ago, making Nabta Playa the oldest stone circle in the world — and possibly Earth’s oldest astronomical observatory. It was constructed by a cattle worshiping cult of nomadic people to mark the summer solstice and the arrival of the monsoons.

“Here is human beings’ first attempt to make some serious connection with the heavens," says J. McKim Malville, a professor emeritus at the University of Colorado and archeoastronomy expert.
