The alleged rules

According to this blog post, women in popular music are sexistly scored according to something like the rule/policy that we can graphically represent by the territory under the following frontier:

I have a lot of other problems with the blog-posting, i.e., setting aside whether the rule allegation is correct, but in fact, I believe its frontier/rule allegation isn't correct, as any even half-way serious (albeit speculative) scatter-plotting would have shown. All your Kate Bush's and Siouxsie's and Aimee Mann's are in the top right quadrant of the graph. Probably Madonna, Gwen Stefani, Roisin Murphy, Chrissie Hynde, Feist, Jenny Lewis, Natasha Khan, and many others are there too. And super-talents with somewhat quirky looks from Tracey Thorn to Bjork to PJ Harvey to (Dresden Dolls') Amanda Palmer, to Carey and Tracyanne Camera Obscura to Tegan and Sara to Angel Deradoorian (all of whom I personally find very attractive - these are geek-goddesses at the very least) are hardly unheard of. Even if enough SOBs score them low on looks though, they've got talent points to burn and should still be, by consensus, above the frontier in the top left quadrant of the graph.

Of course, saying all this has involved us looking beyond our target blogger's principal focus: the true bubble-gum pop market. I agree that that arena is perhaps the most brutally superficial, 'looks first' market of all. Looking like Justin Timberlake or Gwen Stefani or Posh Spice or Rihanna (plus lots of luck) can get you initial success in that marketplace. But sustaining that success normally means proving that you've got real talent after all. Showing that you're more than just a pretty face or a slinky mover is, in most cases, almost like starting all over again. Not 1 in 20 tween-/teen-courting pop-stars gets over that hump, and then goes on to have a substantial, expanding career. That appears to be appropriate, and controlling for (oscillating through the decades) skew by sex in the bubble-gum pop market, I'd need to see serious evidence that that very difficult next step works in any especially sexist way. My own sense is that Justin Timberlake, David Cassidy, every New Kid on the Block, and so on, faced at least as much skepticism and vague resentment as Beyonce, Britney, the post-Spice Girls, and so on did. Getting off the brainless/talentless bimbo track - 'No, really, my looks got me in the door, but I can really play/sing etc., I'm Elton John, I'm Streisand, I'm Agnetha....' - after you've won the bimbo lottery isn't easy for anyone.

In my view, then, rather than allege spurious rules, it would be better just to look at plausible scatter-plots of both male and female popular musicians (i.e., on the same looks/talent axes). Plots we could agree on (supposing consensus about looks and talents scores could be found) might in fact be rather different for male and female stars. I'd guess, for example, that we'd find/agree that there are few, if any truly homely female stars. A sexist factor in culture at large - a double standard about looks that actors/television presenters/news-readers etc. have long complained about - could and probably does apply in pop music too. But what do the talent score distributions for the sexes in music look like after we control for looks scores? Roughly the same? Do they at least have similar means? Is either distribution skewed, and if so how exactly? What are the variances? Studying this would appear to be an interesting project, unlike some others.

You've got to hide your love away

You're making your second film in just over a year, and it's full of knock-out new numbers including Help!, Ticket to Ride, and You've got to hide your love away, any one of which we'd gladly trade Oasis's whole career for.

Still, you're so talented and on fire that, while you're filming, one band-member continues to noodle around on some other little song that he's working on, plonking away on a sound-stage piano every chance he gets. According to wiki, Richard Lester, Help!'s director, eventually lost his temper:

[T]elling McCartney to finish writing the song or he would have the piano removed. The patience of the other Beatles was also tested by McCartney's work in progress, George Harrison summing this up when he said: "Blimey, he's always talking about that song . You'd think he was Beethoven or somebody!

That additional song, which was surplus to the film's requirements and finished later, nonetheless made it onto the end of the Help! album (i.e., as its second to last track). Originally given the dummy lyric title, 'Scrambled Eggs', we know that song as Yesterday. The Beatles had some pretty good days at the office in 1965!

Planet of the Apes (1968) timeline image

In yesterday's post on special relativity and space-travel I mentioned Planet of the Apes's very optimistic time-line for humans to light out to the stars (without warp drive). Here's the key image from the film that establishes what's supposedly going on:

6 months ship time corresponds to ~700 years time on Earth. So how fast is the ship going? Granted the simplifying assp. that the ship's velocity is constant throughout its voyage, it's traveling ~0.999999745C.

Compare: the fastest particles ever produced in accelerators on Earth were at ~0.999999999976C, and the fastest particle ever detected was a cosmic ray proton at ~0.9999999999999999999999951C.

Going Somewhere Fast

Wanna see the universe? Don't care about having anyone you knew back on Earth still alive when and if you return (perhaps not about getting squished to a pulp either)? Then special relativity (SR) is your friend. If you get your spaceship moving close to the speed of light, C (to keep calculations simple, suppose essentially instantaneous accel. and deccel. to constant velocities) then you can travel to a star system x light years away from Earth in ~x years according to a clock on Earth.^[1]
From Earth's frame of reference nothing much turns on whether your ship's cruising velocity is .99C or .99999C (cf., particle collision velocities in Cern's LHC are projected to reach .99999999C): either way you're taking just a little over x years according to clocks on Earth to get to wherever it is you're going. To you on the ship, however, how close your velocity is to C matters immensely: at .99C you spend ~x/7 years in transit, whereas at .99999C you spend ~x/223 years. If your destination is in the Alpha Centauri system (where Avatar's Pandora supposedly lives), then either way your outbound flight takes 4.4 years according to clocks on Earth. At .99C, however, your ship flight-time is just over 6 months, whereas at .99999C, your flight lasts a week.

Here's a graph for some intermediate ship velocities, focusing on in-ship flight times of whole years.

Relying on time dilation effects to help you explore the universe doesn't allow for any of the normal science fiction possibilities of continued interaction with loved ones at home, etc.. All of those possibilities require various sorts of relativity-breaching physics. But even if there's no way around SR, if getting very close to C turns out to be technologically feasible and survivable, etc. then humans could still spread out through the galaxy, but all but the very shortest trips would be importantly 'one way'. From Earth's frame of reference a relativistic diaspora would tend to happen on supra-civilizational or even quasi-geological time-scales. For example, a five year flight out for you at .99999C traverses 1000 light years and sees 1000 years pass on Earth. That's some frontier experience you've bought yourself, pard'ner.^[2]
Very close to C travel by a massy body like a space-ship might depend upon a particular kind of technological and physical breakthrough: essentially on finding some way to 'hide' or 'encode' a lot of the ship's mass as patterns of e-m. radiation. The limit case for this hypothetical possibility would hide or encode all of the mass. Complete masslessness, i.e., complete, (at least) temporary transfiguration of the space-ship and all its contents into e-m. radiation would allow and require travel at C, i.e., as e-m. radiation/light of some kind. That transfigured, massless, informational carrier state would, of course, involve no reference frame/point of view/time factor whatsoever. Decoding/de-beaming/re-materializing a ship with sub-C mass and time in a reference frame as the terminal stage of a 'flight' would be some trick! While realizing this possibility would require huge physical and technological advances, the possibility itself is relatively clear. It represents the least upper bound, limit case for diaspora through the universe that's compatible with SR.

It's somewhat heartening that the mass-less, travel-at-C limit case, while not the 'hyperdrive' of sci-fi dreams nonetheless allows for quite wild arrangements: people in ships get light-like encoded and 'beamed' to new worlds thousands of light years away. Civilizations rise and fall back on Earth while those light-like signals travel to their destinations, all before the next eye-blink of de-beamed/re-materialized time occurs for the people in the ships subject to this process. Their lives restart/continue without missing a beat, notwithstanding that that next beat occurs thousands of light years away, and thousands of years into the future according to clocks on Earth:

'I was just...' - Zap! - 'saying, that would be one small step for a man, and holy mackerel it was! Here I am completing my sentence in 2999 with Altair 4 hanging below me and off to starboard...'

That's not Star Trek or Forbidden Planet, but it's a hell of a space western model. One-way voyages of discovery and settlement into the far away and future: every ship its own, effectively linguistically isolated civilization (effectively the model of 1967's Planet of the Apes).^[3]

Two usefully bleak discussions of the feasibility of non-faster-than-light interstellar travel and associated colonization possibilities:

• Starflight without Warp drive by Landis et al.

^[1] While we effectively assume away accel. and deccel. to ease calculation, it's important that they're still 'really' there. If observers on the ship didn't accel./deccel. then both observers on Earth and observers on the ships would be moving inertially. Einstein's Principle of Relativity would then force all observations to be symmetrical, e.g., if one set of observers sees the others' clocks as running slowly, the other observers must see the first groups's clocks similarly slowed (i.e., since there would then be no frame-independent fact that the ship speeds away from the earth rather than the earth speeds away from the ship). Our cases require clock asymmetries, which implies that they essentially involve accel./deccel.. See John Norton's Einstein for Everyone course notes for patient, detailed explanations of the temptations and pseudo-paradoxes in this area. Wikipedia's time dilation page is excellent, but is too technical and gravitationally-oriented for non-specialists.

^[2] Jesus was supposedly 33 when he was crucified. If, instead of dying, Jesus

• hopped a .99999C flight home to a planet 1000 light years away
• spent several years there generally recuperating and chilling out with descendants of his family
• hopped a .99999C flight back to Earth

then a well-refreshed, 50-ish Jesus could be walking amongst us now.

^[3] Planet of the Apes was heroically optimistic about technological progress, supposing that a close-to-C, one-way expedition to the stars would blast off from Cape Kennedy in July 1972. That makes 2001's speculations about, e.g., large moon-bases and manned Jupiter missions by the end the 20th Century look incredibly sober and cautious! The fantasists of 1967 didn't come close to guessing the somewhat disheartening truth: that 1972 would see the last Apollo mission to the moon, and that 40+ years later, no further manned exploration of the solar system, let alone the universe beyond that, would have occurred.
