The practice of using the letters x, y, and z to represent unknown quantities in mathematical equations can be attributed to the French mathematician René Descartes. Descartes introduced this notation in his work "La Géométrie" (Geometry), which was published in 1637.
In this book, he used letters from the end of the alphabet (x, y, z) to represent unknowns in algebraic equations, while letters from the beginning of the alphabet (a, b, c) were used for known quantities. Descartes' introduction of this symbolic notation was a significant development in the history of algebra, as it provided a standardized way to express mathematical relationships and equations. This notation is still widely used in mathematics today.

BREAKING: Horror story hits the news as a toddler, mother, and grandmother are hauled off to an immigration detention center by Trump's goons because they were speaking Spanish — even though they're American citizens.
This is the worst case scenario...
According to a report from Telemundo Puerto Rico, the three innocent Americans were detained in Milwaukee and dragged off by U.S. officials.
A member of their family stated that they were minding their own business, shopping at a department store when they were detained. Their request to speak to officers was denied until they arrived at the detention center.
"My sister, speaking in English, explained that, not only are they American citizens, but that they are from Puerto Rico, they were born in Puerto Rico," said the family member. The individual spoke anonymously to Telemundo out of fear for their family.
The detained mother eventually produced documents including birth certificates, at which point the officials became apologetic — presumably because they're afraid of a lawsuit.
"I’m so sorry," said one official.
The family was then forced to call and pay for a ride from the facility, putting even more unfair strain on them.
It's still unclear which agency detained them, since ICE's mass detainment and deportation operations are being aided by U.S. Marshals, the DEA, and the FBI.
Please retweet and ❤️ if you think that the family should sue the Trump administration immediately — and consider joining the growing exodus to Tribel, a new pro-democracy social network that is exploding in popularity because Twitter and Facebook are trying to stop its growth — which is only making Tribel grow even faster.

I believe in intuition and inspiration. ... At times I feel certain I am right while not knowing the reason. When the eclipse of 1919 confirmed my intuition, I was not in the least surprised. In fact I would have been astonished had it turned out otherwise. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.

But the mathematicians of the nineteenth century failed miserably to grasp the equally great opportunity offered to them in 1865 by Maxwell. If they had taken Maxwell's equations to heart as Euler took Newton's, they would have discovered, among other things, Einstein's theory of special relativity, the theory of topological groups and their linear representations, and probably large pieces of the theory of hyperbolic differential equations and functional analysis. A great part of twentieth century physics and mathematics could have been created in the nineteenth century, simply by exploring to the end the mathematical concepts to which Maxwell's equations naturally lead.
- Freeman Dyson, as mentioned in Missed opportunities. Bull. Amer. Math. Soc. 78 (1972)
