And from the tiny diamonds before we can now grow large gem quality ones. Same with Graphene, and a long way from the Samsung process.
Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
And yet, I read about a team in Cambridge in the UK who have a new low temperature process that can create graphene in industrial quantities.
Which is rather Stross' point. Here is an example where the cultural norm is wildly different from your own, and you can't imagine it. It might be perfectly acceptable in that culture to say "not interested", it was also important, in the context of the culture Bujold was describing, for reproduction to be controlled, because of extremely limited resources under a dome colony. An extra mouth to feed, and lungs to breath the air was significant to everyone's resources.
The steppers are now all "microstepped", which basically means you don't see quantisation from the drives, but you can't "beat" field rotation, and you'd be surprised how few de-rotators are out there - the imaging guys pretty well all use equatorials, with their attendant problems.
ALL mounts have their issues - an equatorial can't view the area around the celestial pole, and is rarely as stiff as an alt-az for the money. An Alt-az has the field rotation issue, and can't view its zenith.
Mount wars get like computer language wars....
The trouble with Alt-az mounts for imaging is the field rotation, which changes with the scope position, take 10 minute exposures, and you're screwed.
He means the late John Dobson.
I was pretty sure he was immortal. I was wrong.
You'd think so wouldn't you, but no, its not, and the BBC is VERY cagey about rights management.
One of the problems of Lasik is the size of the corrected pupil is often not as large as that of your fully dark adapted pupil, and, as an amateur astronomer, it leaves artefacts in your field of view that are objectionable.
FTFA This wouldn't be an antibiotic, and it seems to happen outside the cell's defensive mechanisms that they can inherit.

...or using the steering wheel....
It takes a surprisingly long time to wash a cabinet out with inert gas. I have an instrument which has to work in an anoxic environment, its only about 2.5 cubic feet, but it takes a good 20 minutes to clear down. A box big enough for a man ?
I think hanging severs the spinal cord, so your're paralysed....while you suffocate to death. Enough people survive dislocation of the neck - Chris Reeves is the most obvious case - to know that death doesn't follow.
