  1. Re:"Valves" in Radios on Transistor Radio Turns 50 · · Score: 4, Informative
    Don't ask me why drugstores carried vacuum tubes.

    Because in much of the USA in those days, drugstores were among the few stores permitted to do business on Sunday.

    Seven-Elevens had tube testers as late as the mid-Seventies.

    You might point out to your friend that the optimum angular resolution of the HST is about 0.1 arcsecond. That represents the angular size of a 600-foot object 238,000 miles away...which means that if the Pentagon and Buckingham Palace were on the moon, the HST would be able to see one and not the other.

    You're still limited by the southern horizon (if you're in the northern hemisphere, of course.) If you're at, say, 40 degrees north latitude, you will never see anything within 40 degrees of the south celestial pole.


    The practical viewing area is even smaller, because objects near the horizon are obscured by atmospheric effects...so there's plenty of advantage to being in space.

    We had plenty of helium then too. We wouldn't sell it to Germany because they had used Zeppelins to bomb London only 20 years before.

    In those days, essentially all the helium in the world came from a hole in the ground outside Amarillo, Texas. It sits atop a big deposit of alpha-emitting ores, and every alpha particle sooner or later picks up two electrons, which makes it a helium atom. Helium was a big contributor to the economic development of the Texas Panhandle, which is why Amarillo is the only city with a monument to an element.

    Everything else aside, this vehicle is safer because it's lighter. There is no substitute for a lack of mass when your vehicle becomes a ball of plastic and metal momentum; the more weight, the more force is required to curb that momentum, so to speak.

    I worked for two of the Paperclippers as an Air Force lieutenant, doing a Master's thesis project on an ion-stream space propulsion gizmo at Wright-Patterson AFB in 1964. The head of the lab was Hans von Ohain, who invented the jet engine at the same time as Frank Whittle in England, although they didn't know about each other...my thesis advisor was Herr Erich Soehngen. He was a Herr instead of a Doktor because -- I am not making this up -- the Eighth Air Force bombed his homework.

    Yes, a lot of our technology owes its existence to war, especially in the 20th century. War was the central fact of our existence, and we lavished our genius and our treasure on it, and tried to deal with the human sacrifice. Well, now that crop of bastards is gone, and we still have the spaceships, high-speed airplanes, and even my lovely German-built sailplane, whose roots date back to a covert program that trained a cadre of pilots for the Luftwaffe. As Jesse Owens said on revisiting the Olympic stadium in Berlin in his old age, "I'm here. Hitler isn't. That about sums it up."

    That brings to mind a vaguely similar series of books: Stephen Biesty's Amazing Cross Sections, which show cutaway views of all manner of engineering works: pyramids, ships of all eras, trains, skyscrapers, on and on...they're very minutely detailed, and in almost every one, there's a tiny little person somewhere taking a dump. (In the case of Lord Nelson's Victory, there's a whole line of guys waiting to use the two-hole head.)

    Not a lot of folks realize how meaningful that is: shit was the very first engineering challenge, and how we get rid of it speaks volumes about where we are on the development timeline. And kids treat it very much like a Waldo book, examining all the details as they race to find the guy on the crapper.

    large banks actually lose money on these moneymakers--at a rate of about $250 a month per machine

    OK, so what does a bank teller make in a month, including benefits and payroll taxes? Add the overhead cost of the human teller (the floor space he occupies, his parking space, maintenance of the bathroom he uses, the time his boss spends supervising him, etc.). Multiply this by three since the ATM works all three shifts, subtract $250, and you have the net benefit to the bank.
