Where do we get our mathematical symbols from? Why is the set of integers called ℤ ? When was the equals sign first used? How about zero? Good notation tends to catch on quickly, whereas bad notation can obscure beautiful theory.
The lecture explores how the introduction of new notation has paved the way for new leaps in understanding, and considers some mathematical quirks of language, such as what the number 4 in English has in common with the number 11 in Russian.

Spiral Dynamics Integral Theory is a Human Developmental model that encompasses all of human development and consciousness into 8 stages. The model was created by Don E. Beck and Christopher C. Cowan, and is based off the work Clare W. Graves had started. The 8 stages are: Beige, Purple, Red, Blue, Orange, Green, Yellow, and Turquoise. Each stage represents a type of worldview, thought structure, and an overall rationale for decisions being made. Basically, each stage represents a sort of track that consciousness runs through. As one moves up the spiral, they gradually take on a position of higher perspective, and gradually showcase a higher level of concern for all sentient beings. This model is important for one to learn as it represents a sort of roadmap that one follows as they self-develop. If you are into spirituality, improving yourself, improving this world, and raising your awareness, this model is absolutely crucial to learn.

About me
Hello everyone, my name is Wyeth and I originally created this channel to share some insights about life and the universe that I had on psychedelics, and how they can be used to change one’s life for the better. Now, this has evolved into me seeking to dedicate my life to understanding the truth about the nature of reality, the self, and consciousness at the deepest level. Because these subjects deal with the fundamental nature of who we are, I believe knowledge from these fields can be used to help one live a more wholesome and authentic life in all aspects.
I pride myself in taking an anti-dogma approach in my inquiry, therefore I will examine all topics of interest through a variety of lenses. If this of interest to you, I highly suggest you become a Curious Mind by subscribing.
If you wish to get in touch with me, you can send me a DM on Instagram (where I post a lot more content about this stuff), or you can email me.

Yvan Sagnet from Cameroon is battling modern slavery in Italy's agricultural sector. Sagnet once worked as a low-wage farmhand. Now he is fighting for the rights of seasonal farmworkers, taking criminal recruiters, or gangmasters, to court.
Yvan Sagnet calls them slaves: the hundreds of thousands of seasonal farmworkers from Africa and eastern Europe on Italy's fields. Without their labor the country would have no tomato, orange or olive harvest. But the workers are exploited and often forced to live under inhumane conditions in ruins or shanty towns called ghettos. In 2011 Sagnet himself briefly picked tomatoes on the fields near the southern Italian town of Nardò. For four days he labored to fill the 350-kilogram crates. He earned 14 euros a day, ten of which he had to hand over to the gangmaster, or Caporale, for transport and water. Caporale is the term for the criminal recruiters who control and exploit the workers. After a 14-hour day working under the blazing sun and even being beaten, Sagnet took home only four euros. He helped to organize the first strike among the farmhands. It was a success, and since then he has been an activist for the rights of the farmworkers and against the gangmasters. Despite death threats, he has set up an organization called NoCap, a label to certify produce farmed under ethically acceptable conditions. And he has taken his fight against exploitation and slavery to the courts. So far, the Italian justice system has responded slowly. It's a fight that will take a long time to win.
