Venus a better colonization target than Mars?

Venus is closer to Earth with shorter transfer times and tons of solar energy. Unfortunately, its atmosphere at the surface is horrifically tremendously high pressure (comparable to a depth of a kilometer in Earth’s oceans) and unimaginably hot (nearly 900 degrees Fahrenheit or over 450 Celsius). Its gravity is closer to that of Earth, which would take more rocket fuel to launch a return flight, but would also probably be better in the long term for human physiology.

A way around most of the problems would be to keep humans off the surface and instead house them in airships or ultimately in floating cities.

It would not be possible for people even to make brief visits to the surface, so mining would be out (barring robotic machines able to withstand the staggering heat and pressure). Almost everything would have to be brought from Earth, though an asteroid could conceivably be mined in orbit. The following video describes some of this:

Review: My Name Is Bruce (2007 movie)

Like a lot of people I enjoy Bruce Campbell’s work, so I was looking forward to this film, which he co-produced, directed, and starred in as parody version of himself. In the end I was disappointed, but there are moments, and you might like it better than I did.

Campbell got his start making Super 8 films in high school with his friend Sam Raimi, soon starring in Raimi’s first commercial feature, The Evil Dead (1981), a horror film with flashes of comedy that was made for so little money that to achieve some camera moves they mounted the camera on an inverted U made of scrap wood and slid it along a 2×4 wrapped in duct tape and covered with Vasoline. (They called the rig the Vas-o-cam.) I learned about this from Campbell’s entertaining autobiography If Chins Could Kill.

Campbell went on to star in the two Evil Dead sequels, the final and best of which, Army of Darkness (1992) involves his character going back in time to the Middle Ages to battle hordes of the undead using among other things a 20th century shotgun and a chainsaw. In a later film, Bubba Ho-Tep (2002), Campbell played a nursing home patient who may or may not be Elvis Presley and who teams up with a fellow patient (Ossie Davis, who thinks he’s John F Kennedy) to battle a mummy. On television Campbell starred in The Adventures of Brisco County Jr (1993-94, reviewed here), Jack of All Trades (2000), and Burn Notice (2007-2013), and appeared in dozens of other television series, movies, and video games.

In this film, an overly enthusiastic young fans kidnaps Campbell to save his town from a vengeful Chinese deity. The “Bruce Campbell” of the movie is washed up loser stuck acting in Z-grade skiffy movies and living in a tiny house trailer. He agrees to help the town mainly because he’s attracted to the young fan’s mother (Grace Thorsen) and besides, what else has he got to do?

(Actually, he’s supposed to be filming something called Cave Alien 2, but when he doesn’t show up on the set one day they just substitute a stuffed dummy and keep filming.)

Much of My Name Is Bruce was shot on Campbell’s property in southern Oregon. Many of the actors are longtime friends, including Sam Raimi’s brother Ted, who has three roles, two of them ethnic stereotypes. Co-star Grace Thorsen is a fellow resident of southern Oregon.

The script, by Mark Verheiden (who wrote Timecop and multiple episodes of the television series Smallville, the revived Battlestar Galactica, and Heroes, among other things), has its moments, but it’s just too dang dumb. I did laugh a few times, but not often, and sometimes I cringed. There are lots of in-joke references to Campbell’s earlier films, to the Three Stooges, etc.

Supertasters

Years ago I read somewhere that people who hate broccoli have a gene that enables them to taste things that the rest of us can’t, including very bitter flavors in some vegetables. Here’s a video about that, which I feel obligated to post here largely because I previously managed to put it into the last post in place of a clip from a Bill Bailey routine (now corrected):

Bill Bailey on doorbells

Bill Bailey is a British comic and musician (and former co-star of the series Black Books) who ought to be better known in the U.S. Here’s a very brief bit on doorbell melodies from a recent performance. (To clear up one joke that might elude some viewers on this side of the Atlantic: What Americans call an “intermission” during a performance the British call the “interval.”)

Review: Sucker Punch (2011 movie)

Sucker Punch is a strange film, self-consciously and intentionally so, with a title that makes no particular sense. Lovely Emily Browning (who was a mental patient at the start of The Uninvited) is here a troubled young woman dumped in an insane asylum circa 1960 by her abusive stepfather, who bribes the staff to lobotomize her to ensure she won’t turn him in.

Things are not what they seem, not at all. The other inmates are all young women, and like them, Browning’s character is given a new name (Babydoll) and a sexy costume to wear. She forms an alliance with some of the others (Abbie Cornish, Jena Malone, Vanessa Hudgens and Jamie Chung) in hope of escaping. In the meantime she has to dance for men (to anachronistically recent music played on old reel-to-reel tape recorders), during which she fantasizes about being a warrior in various fantasy-universe scenes. In one they battle zombie soldiers reanimated by steam and clockwork. In another they take on a dragon with the aid of a World War 2 bomber while orcs storm a castle. In the daydreams she and her friends are sent on these missions by a mysterious Wise Man (Scott Glenn) and have superhuman martial-arts skills.

The film is violent, dark, odd, and occasionally pretentious, but to my own surprise I ended up mildly liking it, in part because Browning is appealing even when not given much to work with. (Roger Ebert said something similar about her.)

Incidentally, according to Browning, the MPAA objected to a scene in which she starts making out with a male character. They didn’t object to the making out as such, only to her being the initiator. Director Zach Snyder decided to cut the scene rather than change it.

Review: The Uninvited (2008 movie)

I’m surprised we don’t see more of Emily Browning, the talented and attractive young actress who played Violet, the elder sister in Lemony Snicket’s A Series of Unfortunate Events (reviewed here). In this film she stars as a teenager who has spent months in a mental hospital undergoing treatment for emotional trauma resulting from the death of her bedridden mother in a horrific fire.

Back home she’s reunited with her loving but somewhat distant father (David Strathairn) and her older sister and closest friend (Arielle Kebbel). But they’re not alone. The attractive young nurse (Elizabeth Banks) who had cared for her mother turns out to be still in residence, having become the father’s girlfriend.

Both sisters consider her an intruder and resent her changes to the house and her efforts to keep the younger sister away from her boyfriend. Gradually the resentment grows into suspicion and then fear.
In the meantime the younger sister sees, or perhaps hallucinates, ghosts, but while the ghosts are frightening, they’re not the menace.

This is a genuinely well-done mystery-suspense film loosely based on a popular 2003 Korean original known in the U.S. as A Tale of Two Sisters. There’s more emotional depth here than you might expect and less in the way of horror movie scares (though the ghost scenes are quite spooky). It’s also intense and troubling, so much so that I found it hard to watch. It’s definitely not the movie to see if you need cheering up.

What’s wrong with sitting?

Like a lot of people, I sit way, way too much, and I keep reading that this is bad for one’s health and telling myself I ought to do something, like maybe get a standing desk or move around for a few minutes every half hour or some such, real soon now.

Last night I watched video this from Dr Aaron Carroll that’s disturbing enough that I might actually do it. It runs under six minutes and as usual cites a lot of serious research:


Link: https://youtu.be/N8tE6zSPJ7w

A couple of observations: First, the randomized controlled trials Dr Carroll cites at the end are only suggestive that moving around at regular intervals will significantly reduce the harm of sitting all day. On the other hand, or leg, or whatever, getting up and moving for a couple of minutes (or more) every half hour shouldn’t be hard to do, and it probably doesn’t hurt. If you move around five or ten minutes an hour for, say, ten hours a day, that’s 50 to 100 minutes of exercise you might not be getting otherwise. And realistically, few of us are going to manage a drastic change from sitting to standing or walking around all day.

Second observation: Dr Carroll does this entire episode from a sitting position.

Carroll did two other recent episodes on the benefits of exercise. The first video below reports that a moderate amount of exercise (on the order of half an hour a day, five days a week) is remarkably good for you. But unfortunately, the second one says that exercise probably won’t help you lose very much, if any, weight. Then again, as he mentions in passing in the video above, being sedentary is associated with weight gain, so at the very least a bit of exercise may very well help you (by which I mean me) avoid getting any fatter.

Maybe I should start reporting on my blog how well I succeed in getting more movement into each day, on the theory that either I’ll be motivated to do something or else it will amuse you to laugh at me.

High-income families in subsidized public housing?

Public housing is supposed to help give low-income families a place to live, but according to a Washington Post report (link), some families getting public help have pretty high incomes, in one case nearly half a million dollars a year.

At first glance that sounds outrageous, but as usual the truth is a bit more complicated, as the WaPo article goes into and as Kevin Drum addresses as well in a blog post here.

In brief, a lot of public housing is funded by the federal Department of Housing and Urban Development, but it’s generally run by state and local governments that, in keeping with HUD regulations, check income before families are allowed to move in but usually not afterward. Some people in public housing manage to get better jobs and make more money — which pretty much everybody from across the political spectrum wants poor people to do — and those who can afford to as a rule find a better place to live when they can.

Exceptions to the rule are rare, which is one reason there’s not much effort expended getting higher-income families out of public housing. But it’s not the only reason: Having a few high-income families around is actually a positive thing, in that it encourages other residents to strive for the same success.

There are obvious downside, too, of course, including the fact that taxpayers end up helping to subsidize housing for people who don’t need it.

But if that’s a concern, there’s a bigger one neither Drum nor the Post mentions: the mortgage interest tax deduction.

To encourage people to buy houses, mortgage interest is deductible against income for purposes of federal income tax (and in many cases state income tax as well). This means that when you pay mortgage interest, you get back some of it in the form of a lower tax bill. How much benefit you get depends on how much interest you pay and what your marginal tax rate is. If you pay $6000 in interest and you’re in the 25 percent bracket, you get back $1500 in reduced taxes. If you pay more interest or you’re at a higher income level, you get even more. If you’re making over half a million a year, you get back almost 40% of interest payments as a tax break. On the other hand, if you’re working two low-wage jobs that put you in the 10 percent tax bracket but you still buy a house to give your kids a better home, then you get a tax break worth only a dime off every dollar of mortgage interest.

Psychologically, a tax deduction doesn’t seem like a subsidy because “you’re just getting to keep more of your own money.” But in terms of real-world dollars and cents, it’s exactly like a subsidy. It makes no difference whether the government increases my tax refund by $1500 or cuts me a separate check for $1500. Fifteen hundred dollars is fifteen hundred dollars.

Incidentally, the “marginal” tax rate is the tax that applies to your last dollar of income. If you’re in, say, the 25 percent bracket, only the portion of your income over $37,500 (for single taxpayers) or $74,900 (for married couples) is taxed at that rate in the current tax year. Moreover, the amount covered by personal exemptions, adjustments, and deductions isn’t taxed at all (and much investment income is taxed at a reduced rate besides be exempt from Social Security tax).
