Surprised three60 hasn't pointed out that Mxy didn't get within 10m of the correct answer

/pedant

[jim360]

He rounded to two sf and Lucky, as the question-setter, has the prerogative to allow answers outside that range should he so wish. So there. Again.

Oh, did JANE guess incorrectly at her own question??  She guessed 1.1 B

(sorry Mxy, hope we're not losing you)

[jim360]

Oh quiet you.

OK here is one I heard yesterday.

A person will do this an average 5 times a day?

Well here is the answer to this one.....Talk to themself

[BFM_Fénix]

DING DING DING DING DING


360!!

No, not the skin, but a good second guess. Considering the skin is the main physical barrier against micro-organisms it was a good guess.

Then...


JANE!!!!!!!!!!!!!!!!!

YES!!! Common sense is better than anything. It is the intestine. In here, all the food that has been "attacked" in the previous processes of digestion will be digested (per se) in here. The gut flora is a main character, since the by-products of their consumption of our food will be absorbed by the intestinal cells.

We are a nice example of symbiosis 

As I said, had not JANE stolen intestines (that sounds weird...) I'd have gone for that. So there.

And as I said, it was a fairly good second guess. "Considering Jane stole your intestines" was implied (specially if you take into account what I said to Widget) yet you didn't inferred it. So there.

I did answer that Rick.

Other than forget what this thread is about... People talk to themselves, maybe?

Name three or more of the craft that hold these world speed records:

1) Unmanned Spacecraft
2) Manned Spacecraft
3) Unmanned Air-Breathing Craft
4) Railed Vehicle
5) Manned Air-Breathing Craft

Hint: They're in order, from fastest first.


Extra credit for providing their speed to the right order of magnitude and two sig-figs....

[Lucky]

Manned spacecraft:  Apollo 13
Unmanned spacecraft:  Hubble Telescope?

[MrMxyzptlk]

Manned spacecraft:  Apollo 13  Nope.  Right ballpark, tho....
Unmanned spacecraft:  Hubble Telescope?  Nah.  'Not even on the list.  It's way too heavy and large to have been in this group...

Keep trying, tho!

[Lucky]

Manned Spacecraft:  Gotta be Apollo 10 then (unless it's some Russian ship that launched around the same time that I've never heard of)

[MrMxyzptlk]

Manned Spacecraft:  Gotta be Apollo 10 then (unless it's some Russian ship that launched around the same time that I've never heard of)

I'll keep a running table, so it's not spread all over the thread:...

1) Unmanned Spacecraft
2) Manned Spacecraft	Apollo 10	BFM_Lucky
3) Unmanned Air-Breathing Craft
4) Railed Vehicle
5) Manned Air-Breathing Craft

Also, I think it'd be better if folks submitted their answers in threes, even if they're just guesses....

[Lucky]

I wish you included the land speed record (un-railed), because I know that one >.>

[·WídgêT·]

Question: for railed vehicles are we talking trains or rocket sleds? Because those are very two different records and two distinct categories (not to mention a MASSIVE difference in speeds)

[BFM_Kiwi]

Unmanned spacecraft would have to be one of the Voyager probes that slingshotted around the sun (and a few planets?) on its way out of the solar system.  Speed is amazing - dozens or hundreds of miles per second.

Railed vehicle - the japanese have fast trains but I'll say the french Tres Grande Vitesse (TGV).  Unless it's a rocket sled like Widget suggested.

Manned air breathing craft - some experimental plane of some sort like Chuck Yeager flew (X-1 or X-5?)

When you say air-breathing, do you mean something terrestrial, or something that literally has an engine that uses air/oxygen?  So a jet as opposed to a rocket?

[BFM_Edison]

What reference frame? ohoho
