Jesus was a real person. Now, whether or not you believe he was the son of God, the Jewish Messiah, a charlatan, or a used wagon salesman is left as exercise to the read. But dude was real.
Crocodilians and dinosaurs (and birds) share a common ancestor. They are all considered Archosaurs, along with pterosaurs and a handful of other extinct species that don't fit into neatly of those groups.
To put it another way, Archosaurs can be defined as a Blue Jay, an American Alligator, their most recent common ancestor, and all descendants (living and extinct) of that ancestor. (Any living bird and any living crocodilian will satisfy this definition).
Dinosaurs, using a similar definition, can be defined as a Blue Jay, a Triceratops, their most recent common ancestor, and all descendants (living and extinct) of that ancestor. (Any living bird and any ornithithischian dinosaur -- Triceratops, Iguanodon, Stegosaurus, Pachycephalosaurus, etc. -- will satisfy this definition. However, using common extinct saurischian dinosaurs such as Tyrannosaurus or Velociraptor will not.)
1. Bryansk is both an Oblast and a city. The Oblast is quite large. The photographs identify the town as Starye Bobovichi, in the Bryansk Oblast.
2. Fallout/contamination patterns are not linear. They are dependent on the prevailing winds.
I read somewhere (can't remember when or the source) that the plan was to send the first recovered core to NM for more flight testing, and to do a full tear-down of the second recovered core.
Sounds like a great plan, except that
$1180 @ 2.5% = $300,000 house
$1180 @ 14% = $100,000 house
There is this called paying cash.
Kinda gets around the who debt thing.
80s landline quality is a vast improvement over every cell phone I've talked on in the past 20 years.
Hey, it's a model that works. "200 Free hours on AOL!"
Science may not be dogmatic, but scientists sure are.
Old scientists don't change their minds; they just die off. You can even still find a few (respected in their day) cosmologists who endorse Steady State Theory if you look hard enough.
I think a better measure here is extinction at the genus level. Genuses are more likely to have fossil records and we can speak of the relative decline of the number of genuses in a proposed extinction event.
Exactly. Mass extinctions are measured by the % loss of genera, not a species count.
(Along those same lines, very few people can name more than one dinosaur species, but they can name several genera.)
Minor point, but it's worth noting both the Florida launch pad (LC-40) and landing site (LC-13) are at Cape Canaveral Air Force Station (USAF), which is adjacent to but distinct from KSC (NASA).
They are planning on launching the Falcon Heavy from KSC, but they have a lot of work to do before that happens.
The first part of the ISS was launched in 1998, and orbital parameters were set long before that. Boris was president, not Vlad.

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
