I shouldn’t have to say this, but earth is nicer than Mars

Furthermore, even allowing for the worst possible case scenarios with environmental disasters and the best for terraforming technologies, earth will always be nicer than Mars.

Caleb A. Scharf writing for Scientific American:

One of those hurdles is radiation. For reasons unclear to me, this tends to get pushed aside compared to other questions to do with Mars's atmosphere (akin to sitting 30km above Earth with no oxygen), temperatures, natural resources (water), nasty surface chemistry (perchlorates), and lower surface gravitational acceleration (1/3rd that on Earth).
...

The bottom line is that the extremely thin atmosphere on Mars, and the absence of a strong global magnetic field, result in a complex and potent particle radiation environment. There are lower energy solar wind particles (like protons and helium nuclei) and much higher energy cosmic ray particles crashing into Mars all the time. The cosmic rays, for example, also generate substantial secondary radiation - crunching into martian regolith to a depth of several meters before hitting an atomic nucleus in the soil and producing gamma-rays and neutron radation.
...

However, if we consider just the dose on Mars, the rate of exposure averaged over one Earth year is just over 20 times that of the maximum allowed for a Department of Energy radiation worker in the US (based off of annual exposure).
And that's for a one-off trip. Now imagine you're a settler, perhaps in your 20s and you're planning on living on Mars for at least (you'd hope) another 50 Earth years. Total lifetime exposure on Mars? Could be pushing 18 sieverts.

Now that's kind of into uncharted territory. If you got 8 sieverts all at once, for example, you will die. But getting those 8 sieverts spread out over a couple of decades could be perfectly survivable, or not. The RAD measurements on Mars also coincided with a low level of solar particle activity, and vary quite a bit as the atmospheric pressure varies (which it does on an annual basis on Mars). 
Of course you need not spend all your time above surface on Mars. But you'd need to put a few meters of regolith above you, or live in some deep caves and lava tubes to dodge the worst of the radiation. And then there are risks not to do with cancer that we're only just beginning to learn about. Specifically, there is evidence that neurological function is particularly sensitive to radiation exposure, and there is the question of our essential microbiome and how it copes with long-term, persistent radiation damage. Finally, as Hassler et al. discuss, the "flavor" (for want of a better word) of the radiation environment on Mars is simply unlike that on Earth, not just measured by extremes but by its make up, comprising different components than on Earth's surface.

To put all of this another way: in the worst case scenario (which may or may not be a realistic extrapolation) there's a chance you'd end up dead or stupid on Mars. Or both.

The situation has evolved in the past three years, but...


I think that the underlying dynamics have, if anything gotten stronger since 2017. Trump's solid base of support is now, by any reasonable definition, a cult of personality. Republicans' ability to distance themselves the administration has diminished as Trump has grown less tolerant of dissent.

All of this raises interesting points about the next few days.

GOP Game Theory -- things are still different

"It's probably better to have him inside the tent pissing out, than outside the tent pissing in."

    LBJ on FBI Director J. Edgar Hoover,

[UPDATE: The conversation continues with The nuclear moose option and The Republicans' 3 x 3 existential threat.]


Let's start with a prediction:
Senate Minority Leader Charles Schumer (D-N.Y.) predicted on Tuesday that Republicans will split with President Trump within months unless the administration changes course.0
"My prediction is he keeps up on this path...within three, four months you're going to see a whole lot of Republicans breaking with him," Schumer said during an interview with ABC's "The View."
Schumer argued while most GOP lawmakers aren't yet willing to break publicly from the White House, they are privately having "real problems" with Trump's policies in his first month.

"A lot of the Republicans, they're mainstream people. ... They will feel they have no choice but to break with him," he said.
GOP leadership are largely dismissing any early signs of discord between Congress and the White House as they slowly try to make progress on an ambitious agenda.


Ed Kilgore, however, points out that Trump may not be as toxic as many people think:

So while it is hard to deny that Trump is amazingly unpopular for a new president, unless his approval ratings trend farther down the way even those of popular presidents typically do, his party may not suffer the kind of humiliation Democrats experienced in 2010. For all the shock Trump has consistently inspired with his behavior as president, there’s not much objective reason for Republican politicians to panic and begin abandoning him based on his current public standing. But in this as in so many other respects, we are talking about an unprecedented chief executive, so the collapse some in the media and the Democratic Party perceive as already underway could yet arrive.



The relationship between the Trump/Bannon White House and the GOP legislature is perhaps uniquely suited for a textbook game theory analysis. In pretty much all previous cases,  relationships between presidents and Congress have been complicated by numerous factors other than naked self-interest--ideological, partisan, personal, cultural--but this time it's different. With a few isolated exceptions, there is no deeply held common ground between the White House and Capitol Hill. The current arrangement is strictly based on people getting things they care about in exchange for things they don't.

However, while the relationship is simple in those terms, it is dauntingly complex in terms of the pros and cons of staying versus going. If the Republicans stand with Trump, he will probably sign any piece of legislation that comes across his desk (with this White House, "probably" is always a necessary qualifier). This comes at the cost of losing their ability to distance themselves from an increasingly unpopular and scandal-ridden administration.

Some of that distance might be clawed back by public criticism of the president and by high-profile hearings, but those steps bring even greater risks. Trump has no interest in the GOP's legislative agenda, no loyalty to the party, and no particular affection for its leaders. Worse still, as Josh Marshall has frequently noted, Trump has the bully's instinctive tendency to go after the vulnerable. There is a limit to the damage he can inflict on the Democrats, but he is in a position to literally destroy the Republican Party.

We often hear this framed in terms of Trump supporters making trouble in the primaries, but that's pre-2016 thinking. This goes far deeper. In addition to a seemingly total lack of interpersonal, temperamental, and rhetorical constraints, Trump is highly popular with a large segment of the base. In the event of an intra-party war, some of this support would undoubtedly peel away, but a substantial portion would stay.

Keep in mind, all of this takes place in the context of a troubling demographic tide for the Republicans. Their strategic response to this has been to maximize turnout within the party while suppressing the vote on the other side. It has been a shrewd strategy but it leaves little margin for error.  Trump has the ability to drive a wedge between a significant chunk of the base and the GOP for at least the next few cycles, possibly enough to threaten the viability of the party.

The closest analogy that comes to mind is the Democrats and Vietnam, but that was a rift in a big-tent loosely organized party. The 21st Century GOP is a small tent party that depends on discipline and entrenchment strategies. It's not clear that it would survive a civil war.

Given that, I suspect the next year or two will prove Schumer wrong. There is some evidence that the president's polling has stabilized, perhaps even rebounded a bit, but even if the numbers go back into free fall, Republicans in the House and the Senate will be extremely reluctant to break from Trump with anything more than isolated or cosmetic challenges.

This isn't just a question of not wanting Trump outside the tent pissing in; this is a question of not wanting Trump outside the tent tossing grenades.

Rhetorical Orthogonality

I'm about to do one of those things that annoys the hell out of me when other people do it, namely taking a well-defined technical concept and trying to generalize it in order to make some big sweeping statements. So I start with apologies, but I think this goes to the heart of many of the problems we've been seeing with journalism and the public discourse (and also explains much of the difficulty that a lot of us run into when we tried to address those problems).

If we think of orthogonal data in the broad sense as something that brings in new information, it gives us a useful way of thinking about the discussion process. I'm thinking in a practical, not a theoretical sense here. Obviously a mathematical theorem does not technically bring any new information into a system, but in practical terms, it can certainly increase our knowledge. By the same token, a new argument may simply present generally known facts in a new light, but it can still increase our understanding. (You might argue at this point that I'm conflating knowledge and understanding. You'd probably be right, but, in this context, I think it's a distinction without a difference.)

My hypothesis here is that (putting aside literary considerations for the moment), good journalism should be judged mainly on the criteria of accuracy and orthogonality, with the second being, if anything, more important than the first. Instead, we often see indifference to accuracy and barely concealed hostility toward orthogonality. We do see a great deal of lip service toward diversity of opinion, but the majority of that "diversity" is distinctly non-orthogonal, falling on the same axes of the previous arguments, just going the opposite direction.

For example, imagine a disgruntled employee locked in an office with a gun. "He's willing to shoot."/"He's not willing to shoot" are nonorthogonal statements even though they contradict each other. By comparison, "he doesn't have any bullets" would be orthogonal. I'd put most of the discussion about liberal bias in the mainstream media squarely in the nonorthogonal category, along with every single column written by Bret Stephens for the New York Times.

Nonorthogonal debate has become the default mode for most journalists. What's more, they actually feel good about themselves for doing it. Whenever you have an expert say "is," you are absolutely required to find another who will say "is not." This practice has deservedly been mocked in cases where one of the arguments is far more convincing than the other (as with global warming), but even when there's some kind of rough symmetry between the positions, it is still a dangerously constrained and unproductive way of discussing a question.

Return of the Space Libertarians -- Quest for the Philosopher's Stone

Wow. We've been at this for a long time.

Libertarians in Space

Herman Cain gave a speech to a group of Young Republicans and the subject of the space shuttle came up:
In his speech, Cain praised President John F. Kennedy as a "great leader" for inspiring a national effort to put a man on the moon, a goal achieved when astronaut Neil Armstong stepped onto the moon's surface in 1969.

"He didn't say, 'We might.' He didn't say, 'Let's take a poll,'" Cain said. "He said, 'We will.' And we did. Only for this president to move us back by canceling a major part of our space program."

Cain also criticized Obama for using Russian technology to ferry astronauts and cargo to the International Space Station.

"I can tell you that as president of the United States, we are not going to bum a ride to outer space with Russia," Cain said to loud applause. "We're going to regain our rightful place in terms of technology, space technology."
I don't know what the reaction of the crowd was (the reporting wasn't that detailed) but I'd imagine it was friendly. You can usually get a warm response from a Republican crowd by coming out in favor of manned space exploration which is, when you think about, strange as hell.

If you set out to genetically engineer a program that libertarians ought to object to, you'd probably come up with something like the manned space program. A massive government initiative, tremendously expensive, with no real role for individual initiative. Compared to infrastructure projects the benefits to business are limited. You could even argue that the government's presence in the field crowds out private development.

(Much has been made of the rise of private space firms, but barring a really big and unexpected technological advance, their role is going to be limited to either unmanned missions or human flights in low earth orbit for the foreseeable future.)

There have been efforts in libertarian-leaning organs (The Wall Street Journal, Reason, John Tierney's NYT columns) trying to argue that interplanetary exploration can be done on the cheap. These usually rely heavily on the blatant low-balling of Robert Zubrin* (Tierney, a science writer who has no grasp of science, made a particularly ripe mark), but even if we were to accept these numbers, it's still difficult to reconcile this kind of government program with libertarian values.

I know you're all tired of hearing this, but there's something strange about equating electability with white and male in 2020.



Glad it's not just me.


Remember when we would have assumed this was a joke?


I have a feeling that this is one of those issues we should be talking more about.


This one goes in the Wages of Strauss file.
 
 We have to check in with the unicorns.



You just knew there was a McKinsey connection.

Back to the 80K question – part 1: why it matters

A while back, we had a discussion on the closeness of the 2016 electoral college vote and how best to quantify it. I argued that the best approach was to look at the minimum number of votes that would have to change in order to get a different outcome. For the last election, that was around 80,000 votes which, I argued, constituted a close race. I got some pushback so I thought I’d fill oout some of the details, starting with why we should bother with the question at all.

Different kinds of wins have different implications, both strategic and psychological. If there’s a disconnect between the way people are reacting and the actual events, that is in and of itself a phenomena worth noting and studying, but if they are making decisions based on those misinterpretations and false narratives, the problem becomes both important and urgent.

The disconnect around the closeness of Donald Trump‘s victory has manifested itself in at least a couple of ways. First is the theory that Hillary Clinton didn’t just lose, but that it wasn’t’ even close. The argument goes on to say that, in order to win, the Democrats would need to add millions to their popular vote advantage to overcome the biases of the electoral college.

Second is the belief that the margin of defeat was so massive that the Democrats need to do everything differently this time. This has particularly centered on going back to what is traditionally considered a more electable candidate. Specifically a white male from north of the Mason-Dixon Line.



Since every woman who has been successful enough to compete at that level will have to deal with charges of unlikeability, this is basically saying the Democrats need to nominate a man, 

Obviously, any conversations about the closeness of an electoral college win are going to be problematic. Every statement will rest on an edifice of challengeable assumptions and definitions, none of which can ever rise above the standard of merely reasonable.

Nonetheless, this is an absolutely necessary conversation. It matters whether or not Hillary Clinton lost by 80,000 votes, 2 million votes, or somewhere in between, both in terms of our analyses and our decisions.

"Now, if we wanted to take the children to see a Komodo Dragon..."

The moderators of this week's Democratic debate have taken some well deserved heat for asking Sanders to respond to alleged comments about the electability of women, then asking Warren a question with a premise that contradicted the first answer.

Putting aside for the moment questions of bias against Sanders, this reminded me of the platonic ideal of inattentive interviewing.

Two reposts



One on the electability of women, the other on the lack of electability of a demographic that includes Biden, Sanders, Buttigieg... (apply all appropriate caveats)

Wednesday, July 31, 2019

Any conversation about electability has got to start with the fact that a white male has not won the popular vote since 2004.

The electoral discussion among pundits and data journalists has been taking some especially silly turns of late and before the bullshit accumulates to the same dangerous level it did in 2016, we need to step back and address the bad definitions, absurd assumptions, and muddled thinking before it gets too deep.

We should probably start with the idea electability. While we can argue about the exact definition, it should not mean likely to be elected and it absolutely cannot mean will be elected.

Any productive definition of electability has got to be based on the notion of having reasonable prospect of winning. With this in mind, it is ridiculous to argue that Hillary Clinton was not electable. Lots of things had to break Trump's way for him to win the election and, while we can never say for certain what repeated runs of the simulation would show, there is no way to claim that we would have gotten the same outcome the vast majority of the time.

This leads us to a related dangerous and embarrassing trend, the unmooring of votes and outcomes. This is part of a larger genre of bad data journalism that tries to argue that relationships which are strongly correlated and even causal are unrelated because they are not deterministic and/or linear. In this world, profit or even potential profit is not relevant when discussing a startup's success. Diet and exercise have no effect on weight loss. With a little digging you can undoubtedly come up with numerous other examples.

The person who wins the popular vote may not win the electoral college, but unless you have a remarkably strong argument to the contrary, that is the way that smart money should bet.

Fun with Political Trivia

This picks up on a recent thread (telling which one might be too much of a clue). The ones and zeros represent a trait of Democratic candidates from 1964 to 2004. Take a look and think about it for a moment. Here's a hint, the trait is something associated with each man well before he ran for president.

Johnson           1
Humphrey       0
McGovern       0      
Carter              1           
Mondale          0           
Dukakis           0           
Clinton            1                 
Gore                1                      
Kerry               0


As you might have guessed, the relationship between this trait and the popular vote didn't hold in the previous or following elections. The trait is not at all obscure. It was well known at the time and figured prominently into their political personas, This is not a trick question.

The Golden Globes are a perfect example of journalism's non-news addiction

[Sorry about sending out the draft form earlier]

Just to get this out of the way, all major entertainment awards are largely worthless. Poor as measures of talent, even worse as indicators of artistic quality, but even by this debased standard, the Golden Globes stand alone in their lack of merit. It has always been and remains a joke.

Winning something like an Oscar or an Emmy probably has less to do with the work and more to do with lobbying and popularity, but it does, at least, represent the approval of the industry. A Critics Choice Award is given by people who watch and write about films for a living. Even the People’s Choice  award indicates a level of popular support. The Golden Globes is given out by a small group you've never heard of. >
The award started out as an excuse to party with movie stars but it quickly evolved into one of Hollywood’s most notorious scams. Here are a few highlights from Wikipedia:

1968–1974 NBC broadcast ban

The HFPA has had a lucrative contract with NBC for decades, which began broadcasting the award ceremony locally in Los Angeles in 1958, then nationally in 1964. However, in 1968, the Federal Communications Commission claimed the show "misled the public as to how the winners were determined" (allegations included that winners were determined by lobby; to motivate winners to show up to the awards ceremony winners were informed if they did not attend another winner would be named). The FCC admonished NBC for participating in the scandal. Subsequently, NBC refused to broadcast the ceremony from 1968 until after 1974.

Pia Zadora awarded "New Star of the Year in a Motion Picture" in 1982

In 1982, Pia Zadora won a Golden Globe in the category "New Star of the Year in a Motion Picture – Female" for her performance in Butterfly, over such competition as Elizabeth McGovern (Ragtime) and Kathleen Turner (Body Heat). Accusations were made that the Foreign Press Association members had been bought off. Zadora's husband, multimillionaire Meshulam Riklis, flew voting members to his casino, the Riviera Hotel in Las Vegas, which gave the appearance that they voted for Zadora to repay this. Riklis also invited voting members to his house for a lavish lunch and a showing of the film. He also spent a great deal on advertising. Furthermore, Zadora had made her film debut some 17 years earlier as a child performer in Santa Claus Conquers the Martians.

The Tourist for Best Musical/Comedy nominations in 2011

The nominations for the 2011 Golden Globes drew initial skepticism as the Hollywood Foreign Press Association nominated The Tourist in its Best Musical/Comedy category, although it was originally advertised as a spy thriller, and also as one of the most panned films of the season with host Ricky Gervais even jokingly asking the main star of the film, Johnny Depp, if he had seen it. Rumors then surfaced that Sony, the distributor of The Tourist, had influenced Globes voters with an all-expenses-paid trip to Las Vegas, culminating in a concert by Cher.




Keep in mind that Zadora and The Tourist only got attention because they were already punchlines before the Globes. There’s no reason to assume the opaque process was any less corrupt the rest of the time.

Everyone who follows the industry knows the Globes are of no news value to the Golden Globes, but every year we get actual news organizations with actual reputations runs something like this:

ARI SHAPIRO: Was there anything among the winners last night that really raised your eyebrows and you think might hint at the future of TV?
The Golden Globes are a perfect example of journalism's non-news addiction. Everyone knows they are absolutely meaningless, at best telling the viewers nothing more than who wrote the biggest check, but no one can seem to resist them.

Efficient infringement -- when it's your fiduciary responsibility to steal stuff

This is a decidedly unhappy sequel to our previous stories on patent trolls, a grim little good news bad news joke. The good news is that we have found a way to prevent trolls from holding companies hostage with illegitimate claims of intellectual property; the bad news is that we did it by taking away the rights of people with legitimate claims.

From Joe Nocera:
If you’re not a patent aficionado, you have probably never heard the phrase “efficient infringement.” Not to blow the punch line, but it’s yet another example of how big tech companies use dubious means to squeeze their smaller rivals. When critics complain that Facebook, Google, Apple and Amazon are squashing innovation, this is the sort of tactic they’re talking about.

I first heard the phrase some years ago when I looked into a patent dispute between Apple Inc. and the University of Wisconsin. The Wisconsin Alumni Research Foundation, which owns the university’s patents, had sued Apple over its use of an innovation that university scientists had dreamed up and patented in the mid-2000s. Apple had installed it in iPhones and iPads without bothering to negotiate a license and had been using it with impunity for years before the case finally went to trial. A jury found for the foundation in 2015 and ordered Apple to pay $234 million.

That was actually a victory for Apple. Consider: Apple got free use of valuable technology that it took from a smaller, less powerful entity. Losing at trial was unfortunate, perhaps, but the $234 million was just another business expense. Pocket change, really, considering Apple’s size.

How common is this kind of move? Boris Teksler, Apple’s former patent chief, told the Economist recently that “efficient infringement, where the benefits outweigh the legal costs of defending against a suit, could almost be viewed as a ‘fiduciary responsibility,’ at least for cash-rich firms that can afford to litigate without end.” In other words, stealing patented technology is practically required if you’re focused on shareholder value. And who isn’t these days?

...

“What is the definition of a patent?” asked Brian Pomper, the executive director of the Innovation Alliance, which represents small and medium-size patent holders. “It means you have the right to exclude others from your invention.” He added, “How can a patent be meaningful if you don’t have the right to exclude others?” But that’s where we are. Companies like Sonos have virtually no leverage to stop bigger companies with deep pockets from infringing their patents.

A media post on Star Wars

This is Joseph.

So a few thoughts on the newest Star Wars movie.

Needless to say: SPOILERS ahoy!

One, the movie was beautiful. The special effects were stunning and the visuals were memorable.

Two, are there no proof-readers in Hollywood? Can we not decide what the antagonist's plan is?

But the part that was the most challenging to me as a viewer was that there was simply no continuity with previous plot points in the other movies. Some of this is forgivable, when you decide on an awesome twist it can be okay to have to patch over a rough spot. Think of Obi-Wan's retroactive deception about Darth Vader, once the writer puzzled out the family tree (or the even more awkward Leia is your sister moment).

But Kylo Ren is just confusing. The second movie seems to give him every chance to decide on his allegiance, even insofar as there was much doubt after the first movie. His history of misdeeds is . . . extreme. He was involved in a mass murder terror attack (Starkiller base). He murdered his fellow students at a school because he disliked the teacher (and focused so much on the other children that the teacher survived). He massacred a village in a terror attack. He murdered a family member as a part of a gang initiation. So his final arc is redemption?

It isn't that it couldn't have been plotted well.  It is just that writers seemed to keep changing their minds, and that is only worth it if the overall outcome is exceptional. The movie was fine, but the plot had a lot of obvious holes (why where the ships buried and were the crews on them when they were)?

Finally, it detracts from the previous movies. What is the point of the middle part of the trilogy now? The heroes fail at pretty much everything and not in a way that teaches lessons or because of a character flaw. No, they fail because the Emperor can survive being blown up and the protagonist doesn't sense the deception.

So it was nice to watch and I am glad I saw it. But it will generate a month of people wondering exactly what happened.

Two more tech spots from CollegeHumor

This one remains sharp and on-target.




This parody of start-ups, on the other hand, can't hope to compete with the real thing in the age of unicorns.
