Carbon carnival

ScienceDaily have an ongoing roundup of organic-chemistry engineering under the "Fossil Fuels" heading. I'll mix up some mint tea as to approach all this with a sober and calm mind. The Baghestan's standpoint is that we don't care about "climate"; and we care about "carbon" inasmuch as we'd rather use it before we let the trees have it. We are also keen to do this chemistry on other planets.

For carbon-dioxide we already got, electrochemical reduction "CO2R" sometimes blows out unwanted byproducts. Among these: if we reduce with a hydrate - like water - said reduction gives off hydrogen. That hydrogen will probably escape - taking with it, the useful chemicals we want, like methanol. Acid and a metal catalyst makes CO2R efficient. The catalyst being gold or zinc.

Meanwhile catalysts could stand, themselves, to use less power. Magnets might help.

Among what we can convert CO2 into is formic acid. Which we've looked at. Also acetates, also looked-at; but now they're saying they can do it by the kilo.

As to the chemicals from CO2R proper, carbon-monoxide seems most-obvious. One of many uses Robert Zubrin had for CO, was for methanol. Enjoy. I prefer tea.

Jesus' epiphany to the Samaritans

Paleojudaica led me to Harry Maier's review of some antiTrump boomer. The two dispute the Samaritan woman account in John 4.

There exists (now) a feminist reading of the anecdote inasmuch as many commentaries assume that the woman was a sinner, which John himself... didn't. Further vide Davidson (pdf). I'll disclose that I concede the point to the feminists. I'll further defend my sex and raise Chaucer as a fellow man who also didn't read this character as a sinner; the Widow Of Bath had run through her own five husbands. With the admission that too-few male exegetes in my language have brought Chaucer to the story. Either-way my post here is not focused on that hermeneutic. Nor on the boomer's general political stance.

Maier suggests that the account is a post-resurrection account in origin. That intrigues me, for this post's focus.

It is Mark, not John, who has taken the hit in classical Tradition for misplacing events in the Gospel narrative. In our context, the Transfiguration is usually considered a Christophany misplaced. Recall that Mark doesn't do postResurrection in what we have (the Catholics' "Longer Ending" probably comes from some harmony or homily elsewhere). But if one evangelist could shuffle events, why not others, since we have at least four of these books, plus an apostolic tradition. Indeed Matthew and Luke don't dispute Mark's placement of the Transfiguration.

John doesn't have the Transfiguration. John's got straight-up postResurrection accounts. Also I cannot find where Meier argues for John 4 as a reshuffle. So I must speculate. What would lead Meier to think it is?

Jesus, here at Sychar by Gerizim, is doing his usual Johannine thing of babbling streams of theology, as the other canon Gospels (and Tradition) wouldn't. That's more the habit of "gnostic" books like the Apocryphon of James. The preachings are done and now is time for the teachings; the SCIENCE, we'd say. Said gnosis is secret, divulged to apostles like Paul in visions. John's revolution was to backdate his own lore into Jesus' mouth before the Cross - at least implicitly.

Now: John isn't all backdated gnosticism. The Cross itself came in real time, that of Pilate. And John offers miracles in parallel with the Synoptics also difficult to claim as postResurrection.

Against that: in John 4's case Christ's miracle isn't upon this physical world. For instance Jesus isn't bringing any of this woman's husbands back; surely she must have retained affection for at least one of them, like the Bath widow did. As to Sychar's landscape its well isn't dry as (say) Luke 4:25 was noting of the days of Elijah. John 4 offers a story like Emmaus where someone shows up and eventually the audience realises they're talking to Christ. Christ's presence is the miracle. It is just that then immanu-mashiach, as it were; which means at Sychar unlike Emmaus it's not so miraculous.

StackExchange, basically nerd Reddit, brings Matthew 10:5-7. Matthew's Christ had told his disciples to avoid the Samaria. In John 4, Jerusalem is about to lose its primacy even for Jews (v. 21). The Cross would be a drastic marker of Jerusalem's abandoned status. Perhaps John's pool of tradition postdates Matthew's. That might suggest a Samaritan composer bringing the Gospel, at last, to her own people; Christ has lifted the embargo, and by this story He has done it in person. All this, John will chuck into his Tardis. I guess?

John 4:31 "meanwhile" - that is, as a sidenote - has the disciples note that the Master isn't eating. The concern with whether the Lord eats is that of the Docetism controversy, such as Ignatius confronts - which trends postResurrection. However vv. 31-8 doesn't need to belong to this particular anecdote, which concerns water and not food (nor wine!). If we're shuffling one story, we can hardly resist shuffles of pericopae within the story. It remains suggestive that John, at least, associated these two anecdotes.

I suppose my readers will just have to ask Maier.

Boozeworld

As we were deciding on carbon, hydrogen, oxygen, and nitrogen (CHON) in space and on Earth (respectively): here's ISO-Chamaeleonis-I 147. Lots of the former two elements. Less of the latter two.

It seems that the ultracool stars, like GJ 12 and TRAPPIST-1, don't come with oxygen. So what's had are the organic classics: acetylene (first seen, from Earth), ethylene, benzene, even that classic of Titan ethane. These are seen in a 300 K cloud. So pretty much the weather here this past week but without the ozone.

Such planets might not be enriched in these compounds if the reason for all these hydrocarbon gasses is that the star has blazed them off the rocks. But, presumably, the gas'll form comets (at low distances from such cold stars) which might end up crashing back into the planets.

The research doesn't speculate what this sort of oxygen-depleted planet might look like except that it is certainly not Earthly. Soot planet again? Gasoline and ethanol seas?

Don't bring your scuba to Mars

I know this was satire, but it just got funnier. The satire has come to be at Zubrin's expense more than at Musk's. I too am getting laughed-at by proxy, because back in fateful 2020 I believed these reports of liquid lakes on Mars - rather, in it, under the southern caps. Seems like... nah. Big nah.

In all fairness to Zubrin, if not to me, we keep finding water ice. Zubrin's suggestion was for the crater Korolev which was never tagged for subglacial lake.

The real takeaway (despite keeping watch for gullibility) is to remember that humans... aren't there. We're not even in orbit. So the data we get must be interpreted, against models. The models are improving. But incomplete models will yield "AI hallucinations".

SEISMIC 6/25: Maybe the lakes are further down? Seems like all so much crossing-T and dotting-I but then, science sometimes has to work like that.

The latest crash

The Gaia telescope is sketching the process of our galactic Creation. This blog has discussed our galaxy's consumption of clusters like Omega Centauri, and the mergers which made our core. Now from Rensselaer Poly: the Virgo Radial Merger, in the inner halo.

Here are a set of stars we know aren't native to this place. These were earlier thought to belong to the much-earlier Gaia-Sausage-Enceladus merger. The VR merger was 3-1 Gya, although the presser and the study prefer 2-1 for most the magic. I take it that both mergers were already defined, but that the VR was more-questionable. The VR must have been mooted recently since I'd thought the Sagittarius was the latest. Now the VR is solidly defined.

The VR should have sparked some star-formation, lighting up some nice supernovae over our Boring Billion skies. I don't think anything with a brain was yet swimming in our scummy ponds and shoals.

The cart before the horse

Horses were domesticated around 3000 BC; the Yamnaya invaded Europe around the same time. Today we are relearning the limits of circumstantial evidence; this blog recorded hints of the present study, three years ago.

To repeat: the first domesticate horses were of the Botai. These were not the horses which the Yamnaya and, then, R1a-'ryans would use out East. This means that the Yamnaya migrations didn't use horses, as Botai might. Horses came to the post-Yamnaya Europe, later: the 2200s BC. And to Anatolia later.

The pedestrian Yamnaya invasion still must be explained. A culture able to traverse the distance beyond local clan, I think. Even without horses and chariots, the humble cart - handdrawn - could scale up commerce and migration. Also: how about donkeys and oxen?

Anyway as B. Breathed noted of "having your cake and eating it", "cart before the horse" needs to be retired as a dead cliché.

JOSTLE 9/23: Yamnaya had cart-bruises. But - they point out as I'd pointed out - you can cart with cattle, donkeys and even wild asses.

Adobe addio

I'd been using a free Acrobat solution to edit documents. I don't trust its company Adobe to keep their hands off my stuff. I'm trying PDF24.
