What's stopping academic research on ideas covered by patents?

You should have paid closer attention. Your "reward" will be 70 very ugly virgins riddled with various diseases who will constantly be fighting with each other, and who will always be jealous of each other. Plus they will have only one hobby - nagging at you. Have fun with your paradise, my friend.
Your sarcasm only makes sense if you think GP was serious. I hope that is not the case.
Your link only reaffirms what GP already recognized: astronomers combine all elements except hydrogen and helium into one large group calls "metals" and then measure an object's "metallicity". The question that was asked is why did astronomers choose to use the specific word "metal"? The word already had a very specific meaning in science and in common usage. So were the astronomers just being lazy or was there more meaning to the decision?
