I paid for two daughters' pretty-big weddings, one in Austin and one on a golf course near Lake Tahoe. The bride and groom came down the isle in a golf cart and almost wiped out a couple of bridesmaids. Austin, I mostly remember the mosquitoes. So far, neither looks to need another guy. Girls are cute but expensive.

Both he and she were fully qualified lawyers, albeit working in completely different fields. First, they moved the material stuff to a different treaty, zeroing the financial value of the case. Then my brother represented both himself and and his ex as a lawyer. Net result was just the writing cost of the court. Such a thing takes some discipline. Gerhard

Best wedding I was ever at, just about 39 years ago. According to Isaac Asimov, he used to introduce people to "Janet, my first wife." (Neither married more than once.) She always responded, "Oh, Isaac." Cheers Phil Hobbs

Already light weight but extremely strong sports equipment are being made with this material. The base material for gtaphene is abundant(compared to copper) and processing it much simpler.

Loads of people have looked at them, but commercial quantities of properly insulated cable with connectors on either end still seem to be some way off. Sticking metal atoms in the centre of the nanotube is another trick that does interesting stuff in the lab but hasn't yet lent itself to mass production either. https://en.wikipedia.org/wiki/Carbon_nanotube -- Bill Sloman, Sydney
