Today would be the 100th birthday of legendary Hungarian mathematician Paul Erdős. Among his many accomplishments, Erdős is perhaps best known for being the most published mathematician of all time (1500+ papers), and his extensive collaborations with other mathematicians, which is reflected in the establishment of the Erdős number.
[He] was an influential mathematician, who spent a large portion of his later life living out of a suitcase and writing papers with those of his colleagues willing to give him room and board. He published more papers during his life (at least 1,525) than any other mathematician in history.
The idea of the Erdős number was created by the mathematician’s friends as a humorous tribute to his enormous output as one of the most prolific modern writers of mathematical papers. The Erdős number has become well known in scientific circles as a tongue-in-cheek measurement of mathematical prominence.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
