AI Thread Summary
The discussion centers on the concept of synesthesia, particularly how individuals associate colors with numbers, such as the number 20 being perceived as a blend of the colors corresponding to its factors, 2 and 0. This raises questions about the nature of arithmetic perception—whether the color association is inherent or learned through education. The conversation explores whether a person without knowledge of basic arithmetic would still perceive the number 20 in the same way or if their perception would be arbitrary. Additionally, there is curiosity about the physical experience of seeing these colors in relation to numerals, emphasizing the subjective nature of synesthetic experiences. The link to ideasthesia suggests a broader context for understanding how concepts and sensory experiences intertwine.

The girl says that the number 20 has a colour that is a mix of the colours of 20's factors. I find this interesting, because I always thought arithmetic is imaginary, right? If she didn't learn basic arithmetic, would 20 have had the same colour? Or would 20 have the same colour, but to her, the colour would seem random to her?

Interesting, I have synesthesia, but it's just a direct correspondence between each letter/digit and a color. So 20 has the color of 2 and then the color of 0.

Do you physically see the colors superimposed on the numerals out in the real world? Is it a visual experience?

Thread 'Did they discover another descendant of homo erectus?'

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...

Thread 'Warning of new opiod drug (nitazene) on the streets: Question re strength...'

Whenever these opiods are mentioned they usually mention that e.g. fentanyl is "50 times stronger than heroin" and "100 times stronger than morphine". Now it's nitazene which the public is told is everything from "much stronger than heroin" and "200 times stronger than fentany"! Do these numbers make sense at all? How do they arrive at them? Kill thousands of mice? En passant: nitazene have already been found in both Oxycontin pills and in street "heroin" here, so Naloxone is more...
