Comment Re:Fucking anti-social Millennials (Score 1) 120

I bet you're that guy at the front of the line who misremebers the price of what you bought and makes them send the bagger sauntering to the back of the store for a price check, and then doesn't even start to open his 19th century checkbook until the final tally is rung up, and then fills the whole check out glacially topped off by a pointlessly legible signature, then finally hands the check over so that the cashier can slowly scribble the entire contents of your drivers license over it.

And you wonder why I'm so thankful for self checkouts, even though I'm not even nearly a "millenial".

It has been common for the government to have public executions without trial when an american citizen is known to say "bad things"

Saddam Hussein did a little more than just saying "bad things"

I wasn't aware that he was an american citizen.

Plus we didn't off him when he was murdering Kurds and other "undesirables", or when he started a revanchist war against Iran that resulted in several hundred thousand, possibly a million, casualties. He only got in the doghouse for seizing Kuwait, threatening the carefully engineered balance-of-powerlessness established in the middle east by the the allies after WWI.

Comment I had iLASIK about 11 months ago. (Score 2) 550


iLASIK is done with all lasers, one to make the flap that was previously done by blade, and the usual LASIK after that. Fewer reported complications than with the older blade style. At my six month checkup I was seeing 20/10 from my left eye and 20/15 from my right. I'm 48 and previously wore progressive lenses. They adjusted my right for a closer focal distance.

It all just works, I love it.

Comment Re:How did they launch from the moon? (Score 1) 211

I've never understood how they were able to launch from the moon back towards Earth. Launching from the Earth requires massive infrastructure and huge rockets. Yes, the moon's gravity well is shallower, but still significant.

It's because the fundamental equation that relates a rocket's performance and the mass fuel it requires to orbital velocities is exponential. This makes it work out so that any chemical rocket leaving earth has to have the vast majority of its weight as fuel, where as a rocket leaving the moon only about half of its weight as fuel.

What's more, the entire lunar module and its fuel supply is dead weight as far as the earth launch is concerned, which makes the earth rocket and its fuel multiple all the bigger. Then there's the issue of bringing along enough fuel to slow down the craft into lunar orbit, and escaping lunar orbit back to earth. The lunar lander didn't need to handle any of that, either.
