[ATM] Time to change message content?
I'm all for dumping America Off Line. And, even though many us are grumpy old men, this isn't exactly the proper forum for expressing it.
If you must muse, as I have and no doubt will again, do what Mike did, add a few lines about telescopes or something related to ATMing.
Lord Rosse completed a 1.82 meter (60 inch) diameter speculum mirror in 1842. It was composed of 68.2 percent copper and 31.8 percent tin by weight. This ratio he wrote was ideal for polishing. It also corresponds exactly to Cu4Sn. What delta bronze was thought to be up until the 1930's. An early ratio used for bronze metal mirrors for hundreds of years was two thirds copper, one third tin. Again, by weight. This ratio corresponds exactly to Cu41Sn11. What is now know to be delta bronze.
