Dhalgren by Samuel Delaney is exactly what you are looking for.

I'm not sure if it would be helpful for your project, but you might be interested in the concept of the grammar of graphics (https://towardsdatascience.com/a-comprehensive-guide-to-the-grammar-of-graphics-for-effective-visualization-of-multi-dimensional-1f92b4ed4149).

I use a version of this in R as implemented in ggplot2. What is nice about it is that you can use standard text descriptions to build an arbitrary graph.

I had this posted over my when I was at engineering college!

I think I'm saying that mining on asteroids will probably never be profitable or realistic (with a possible exception of carbon, hydrogen, oxygen, nitrogen CHON once people are living on orbit). Mining on other planets might require understanding different geology and maybe different refining technology. Anything mined on a planet will likely stay there. But there just won't be any ores on asteroids because they never had a chance to differentiate into higher and lower concentrations of various useful metals.

Metallurgical engineer here. One thing I never see talked about on this topic is how astreoids don't have nearly the mechanisms for concentrating matals into ores like planetary bodies do.

So while there may be a higher proportion of, say, iridium on an asteroid than the average of Earth, it is pretty homogenous. You would have to refine the whole thing to get a little bit of iridium. On Earth, it may be more rare on average, but Earth also concentrates metals into ores via heat, gravity and water action so that you can mine a small area to get what your want economically.

Metal meteoroids are mostly iron, which is cheap on Earth and of little use in space. Aluminum, which is useful in space, is one of the most common elements on Earth and even higher on the Moon,, but it's only economically mined in tropical soil that had ages of water erosion. Titanium, different process but similar story.

Given the economics of getting to where you want to mine, mining a non-concentrated rock, and then transporting it back to Earth's for sale I just didn't see any path for mining asteroids.

Once there's is an established human presence in space, there might be a reason to mine organics (CHON) but that is not now and not what people think of when they tout asteroid mining.

The Supreme Court has no jurisdiction over a political party's nomination process. That said ...

From a jury I was being considered for (sexual assault), is not that you have no opinion, it is that you think you can be objective based on the evidence.

It's not scare quotes. Just indicating a verbatim quote from her ex.

His name will be on the ballot, but if scotus finds that he's ineligible he can't win the nomination here, so vote for him would be wasted. Well, it's wasted no matter what but you know what I mean.

Lots of great advice. The one I might add that we failed at miserably is understanding and appreciating mental health issues. I really recommend that you educate yourself and your partner on what to keep an eye out for and check in with your kids to see how they're doing.

You can resist your dark urge too. That has a fun ending too.

Hey, new to the Fediverse and thought I would put this out there.

If you teach stats or use stats in your job, you might be interested in using my GUI for R. I hope this doesn't count as an ad, since it is free.

I like how versatile R is, but I hate remembering how to type in what I already know it can do.

So I wrote an app.

You can tell I am not a programmer or a computer scientist (I am an engineer, industrial researcher and occasional teacher) but it works to do the basic to the moderate stats you probably use all the time.

It is free. I just put some of my blog posts and books on the splash page. If you register I only send you info about the app.

Let me know if you would like any enhancements. I continue to add stuff to it until I can do most of what the practical researcher would need.

 

Internal emails highlight how an advertising company can use its in-house resources to oppose public policy proposals.

One of the world’s largest advertising firms is crafting a campaign to thwart a California bill intended to enhance people’s control over the data that companies collect on them.

According to emails obtained by POLITICO, the Interpublic Group is coordinating an effort against a bill that would make it easier for people to request that data brokers — firms that collect and sell personal information — delete their dossiers.

 

US District Judge Tanya Chutkan said that she plans to put serious limits over how sensitive evidence is handled in the Donald Trump 2020 election interference case, in a dramatic hearing Friday in Washington, DC, that could set the tone for the upcoming trial.

The former president has a right to free speech, but that right is “not absolute,” Chutkan said. “Mr. Trump, like every American, has a First Amendment right to free speech, but that right is not absolute. In a criminal case such as this one, the defendant’s free speech is subject to the rules.”

 

I can't figure it out.
