Re: CoRoT Rocky Planet (APOD 2009 September 23)
A link to this article ... http://news.yahoo.com/s/ap/20090916/ap_on_sc/us_sci_rocky_planet ... showed up in my Yahoo News headlines a week ago, and there I first saw the image used as today's APOD. The only trouble was that the article makes it sound like ESO announced the discovery of CoRoT-7b Sep...

The bananas are simply creases in the hood which has been tightened over the face to keep out blowing sand. The saucers are the sun near the horizon and a small cloud above.

Re: If theories must be disprovable, what value are they?
A theory about chimps or anything else could be a scientific theory or not, depending on the phrasing. Does it specify a rule that can be tested? Your chimp theory includes the word "could", so it's not so much a statement of a rule that "always" applies. So, unlike what I descri...

Re: If theories must be disprovable, what value are they?
Disprovability applies to scientific theories. A scientific theory states that a phenomenon always follows one or more rules, or it proposes a mechanism for a phenomenon that is reflected in one or more rules that are always followed, or it specifies attributes of a phenomenon that are defined by on...

Re: poll: should sputnick aka aristarchinexile be banned
Having a blatantly incorrect view is often characterized as having one's head in a specific location that provides zero visibility. Such a position can only be achieved through difficult unnatural contortion. The medical term for the debilitating condition that produces the required contortion is cr...

Re: Antarctic Ice Shelf Vista
Try your math again. The problem is that both regions stated are in square kilometers which only refers to surface area and not volume or cubic meters. I divided area (ocean) by area (ice shelf) to get a dimensionless ratio. I multiplied this dimensionless ratio by height (sea level rise) to obtain...

Re: Antarctic Ice Shelf Vista (2009 Feb 15)
If the Ross Ice Shelf is lost, then the entire ecosystem that depends on dark cold water underneath an ice sheet is totally disrupted. The collapse of Larsen B has revealed a thriving ecosystem 800 m (half a mile) below the sea. "Despite near freezing and sunless conditions, a community of cla...

Re: Antarctic Ice Shelf Vista
If one makes the assumption that the Ross Ice Shelf melted in its entirety, along with the balance of the other Ice Shelves in Antarctica, then a total of 1,183,590 sq. Km's of ice would melt. Using Rocky's figure for the total area of the oceans and dividing by the total area of the ice shelves in...

I essentially agree with what you said.
The first four terms are in quotes because I used them loosely and don't care to defend them.
The term "scientific documentaries" is in quotes because IMO they are really neither.
