Last year I replaced several windows in my house and they were the expensive double-pane energy efficient kind. But this week I got a call from the contractor complaining that his work has been completed for a whole year and I had yet to pay for them.
Boy oh boy did we go 'round. Just because I'm blonde doesn't mean that I am automatically stupid. So, I proceeded to tell him just what his fast talking sales guy had told me last year. . that in one year the windows would pay for themselves. There was silence on the other end of the line so I just hung up and I haven't heard back. Guess I must have won that silly argument.

Stellar parallax

In 1839, the Scottish Astronomer Royal, Thomas Henderson, published the results of his measurement, the first made of a stellar parallax. He observed the star Alpha Centauri from the Cape of Good Hope, South America. (It is not visible from Britain.) His measurements were made in 1831-33. After that time, but before Henderson completed his calculations and published his results, both Friedrich Bessel and Friedrich Struve had been recognized as the first to make measurements of stellar parallax.«[Image: The effect of parallax for a nearby star S is to observe it apparently in line with star A when viewed from Earth in July, but apparently in line with star B in January. (The diagram is not drawn to scale.)]
