It weighs 1 million pounds (454,000 kg)
ghaaaaa! Not only are pounds medieval units shared with only Myanmar and Liberia, 1 million pounds is NOT 454,000 kg. While 1 million lb is only one significant figure, 454000 means at least 3, possibly more depending on the interpretation. The actual masses are 924,740 lb and 419,455 kg resp. These figures themselves have issues as propellant loss among other will make the last few digits variable. But the 454000 figure is way off.
Although the first gravitational lens wasn't discovered for some 40 years after it was first theorized
Eddington demonstrated gravitational lensing just a few years after the theory was published, in 1919. And he would possibly have been quicker if if weren't for WWI
That they miss their plane because their alarm clock failed.
or they forget the kid, and while he's home alone a pair of FBI agents try to enter his home to arrest him, only he makes up more inventions to stop them.
Well, ok another nitpick - if he had chatted a bit more with biologists he could have made the potato thingy more interesting.
What I was wondering while I read the book is: would it be possible to bypass the plant state and just synthesize nutrients using tabletop chemistry? Not very palatable, but potatoes get boring.
The single most mind blowing photo for me? Hubble eXtreme Deep Field http://www.nasa.gov/images/con...
Too bad the picture was photobombed by Milky Way attention whoring stars.
A failure will not appear until a unit has passed final inspection.
