  1. There's a lot more discussion that can be had about the financing of capital improvements in the regulated Bell System vs. the heavily debt-leveraged unregulated cable systems and later cellular phone systems. Bell did not need to supply the phones to continue making a profit, as their rates were regulated to guarantee a "fair" profit. On the negative side, regulation prevented them from cross subsidizing between local service, long distance, and innovative services. Cable TV companies, on the other hand, needed the additional income from set top box rental to help service their tremendous debt for capital expenses, though they stubbornly denied it (probably because they wanted to avoid inviting potential government regulation). When legislation was passed allowing customers to purchase their own cable TV terminal equipment, the cable operators did not make it easy (some would say they deliberately made it nearly impossible). If the cable companies had become regulated, they would still have made a (smaller, guaranteed) profit, like Bell, but their lenders would have done a much smaller business, and the build-out may have been slower. On the other hand, while the Bell monopoly did tremendous research, they mainly applied it to improving POTS (plain old telephone service) over their copper wire home connections.

  3. LIFE, April 13, 1962, mentions the Picturephone at the Museum of Science and Industry in Chicago. I haven't found a reference to the extent of time it was there. At various times it was connected with Disneyland and the Franklin Institute in Philadelphia. I once made plans with my cousins in California for them to be at the exhibit in Disneyland when I was at the museum in Chicago. https://books.google.com/books?id=lk4EAAAAMBAJ&pg=PA12&lpg=PA12&dq=picturephone+at+museum+of+science+and+industry+years&source=bl&ots=8_7RZJ_0cW&sig=q0ylZlStusbevRC2U06klVgLIrk&hl=en&sa=X&ved=2ahUKEwiAu62K-oPeAhURG3wKHbc0AxYQ6AEwFnoECAoQAQ#v=onepage&q=picturephone at museum of science and industry years&f=false Speaking of advances in technology, a machine that played TIC-TAC-TOE was a long-time part of the Bell exhibit at the museum, but it was built entirely from mechanical relays, not a computer program.

  5. Thanks for the California Gold link - it's great!
  6. So much for the polls

    I remember on TV talent shows that used a sound meter to gauge audience approval, the needle would go way upscale if anyone in the audience whistled loudly. Plus it's very likely that whoever went second would get a boost because his/her supporters would be sure to try outdoing the level they heard for the first contestant.

    Here's a better difference image, this time carefully adjusted to cancel out the reflections as much as possible, and contrast boosted. I realize now that the reflections and the sign lettering cannot be canceled simultaneously because they were at different distances. Now you can plainly see a streak extending through the center.
  8. https://www.thisdayinaviation.com/tag/boeing-model-314/ says that the Boeing 314 engines were rated 1200 HP at 2100 rpm, and drove the props through a 16:9 reduction gear. Prop speed was then 1181.25 rpm, or 19.6875 rps, approx 20 rps. 20 rps = 7200 degrees per second. Since the prop blur in the picture appears to be roughly 30 degrees, the shutter speed was approx 30/7200 = 1/240 second, if the engines were at full cruise speed. If the engines were running slower, the shutter speed was longer.
  9. According to Wikipedia, Kodachrome at the time was rated ASA/ISO 10. The "sunny 16" rule says that at f/16, the shutter speed would be 1/10 second (this shot was obviously much faster), or 1/320 second at f/2.8, or 1/160 second at f/4.
  10. Great article. I never heard Lundy's term "space flower," but if he had said it to me, I would have replied that it's more like a "space berry." How do other people here compare these to the other fair architecture? I have to say that I don't agree with the gushing architecture critic who thought the space flowers exceeded much of the other architecture at the fair. I don't know, maybe it's because I feel the repetitious use on so many snack bars destroyed some of the feeling of uniqueness, even though I never saw anything like it before or after. And maybe it's because they failed in a practical sense by showing dirt so badly. Nevertheless, I wouldn't suggest any alternatives - they certainly had a unique association with the fair.

    Here are the two shots that I took. #1 actually has a long but faint series of sparks down the middle, that are veiled by the reflections in the glass, in addtion to the single bright one near the bottom. I made an image of the difference between #1 and #2 and enhanced the contrast and color saturation so you can see it better. #1 Bright sparks near bottom and long faint streak of sparks top to middle: #2 #1 minus #2 brightened crop of bottom of #1 Edit: the more I look at this, the less sure I am it's an actual long streak and not just a misregistration of reflections in the two images - will have to return to Photoshop and see what I can do.

    It might be that there's a critical setting of voltage to get sparks from cosmic rays and not have it sparking randomly due to local radiation, ionization due to room light, etc. If so, then some of the gaps along the ray path might not spark, which is what seems to be happening.

    Thanks - that was great
