Man's brain turned to glass by hot Vesuvius ash cloud

&gt; ... scientists have discovered that his brain was preserved when it turned to glass in an extremely hot cloud of ash.<p>&gt; The pea-sized chunks of black glass were found inside the skull of the victim, aged about 20, who died when the volcano erupted in 79 AD near modern-day Naples.<p>&gt; ... a cloud of ash as hot as 510C enveloped the brain ...<p>I don&#x27;t think I&#x27;d use the word &quot;preserved&quot; to describe there being a few glassy cinders left over, after someone&#x27;s brain was incinerated.

Supposedly this vitrefied brain is mostly carbon and oxygen.<p>Interestingly, there is a glass-like form of carbon (just carbon):<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Glassy_carbon" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Glassy_carbon</a>

There was a Tiktok trend where (typically) women were shocked to discover the (typically) men in their lives thought about the Roman Empire as much as they do, often on a daily basis. The question is why.<p>To me, it comes down to Rome not being the oldest or even the necessarily the largest or longest-surviving empire. It&#x27;s that it&#x27;s the most well-documented ancient civilization. Sites like Pompeii and Heculaneum provide a time capsule into ordinary existence that is often missing from ancient accounts that typically talk about kings, emperors, wars and so forth. In addition, we have a ton of texts from that time, including the direct writings of the likes of Julius Caesar.<p>Rome continued to influence European history beyond the fall of Constantinopole up until the 19th century through the Holy Roman Empire.<p>But the impact is still felt today. Classics such as Marcus Aurelius have arguably been co-opted into the alt-right pipeline.<p>There&#x27;s also interesting psychology at play here. People like to imagine themselves in such a world. Where in the real world they might be just an average working Joe, people rarely imagine themselves as being peasants or slaves or a grunt in the army despite those being the majority of people.<p>I find that last point needs highlighting because there is an effort to reshape our current society, driven by real yet misplaced legitimate anger. Human ego being what it is, nobody acknolwedges the statistical likelihood that if you&#x27;re suffering or oppressed in the current organization of society, you&#x27;re probably going to be oppressed or otherwise suffer in a new society, particularly one built around an autocrat.<p>But when the central organizing principle becomes cruelty, perhaps aspiring to being a Brownshirt is the goal.

Are the neurons preserved in a recoverable way, like 5D optical glass-based data-storage? Also Chinese (and probably other languages) has a common derogatory expression &quot;Glass heart&quot; by which they mean &quot;I think you are too sensitive to what I see as valid criticism of you&quot; - this glassy brain preempted that slur at an intellectual level.

Once fell down, from volcanic gas.<p>Soon turned out, I had a brain of glass.

Reminds me of the brain of a man that went down with the Swedish warship Vasa that was found preserved (turned into soap.)

Someone should have shown that to the &quot;Rings of Power&quot; screenwriters, because in that show Galadriel comes out of the volcanic ash cloud with just her hair messed up :-D

I learned a while ago that more than half the population of Pompeii and Herculaneum fled and survived the destruction of their homes. And the ensuing refugee problem lasted a while in nearby settlements, including Napoli.<p>So it&#x27;s likely that the ones who remained and died were either stubborn or disadvantaged somehow, as well as those just unlucky.

... Oh, in the Pompeii eruption, not, like, breaking news. Given the general surreality of 2025 news thus far, would not be surprised.
