Re: Polar storm?
Yes, it's called the 'hemispheric long wave pattern' and at the moment it has four troughs (at other times I've seen three or five troughs). It is useful for long-range rain forecasts, e.g. http://www.weatherzone.com.au/long-range-forecast/28-day-rain/act/act
Just wait 12 hours...
I'd estimate we are currently Bbb's?
You post an equation which estimates we will find two exoplanets with signs of life within the next ten years, and from that you conclude "Odds are we won't find any".
Re: Intelligent alien life?
I'd settle for them finding intelligent life working for a government department !
Oi! Public servants ≠ politicians.
Did you just seriously suggest "killing off maritime plankton"??????
Re: In-House is always better, it seems...
If you want something done properly, do it yourself.
Re: So they lost an unmanned rocket, but gained a safety feature for the manned version...
I'm a bit surprised they didn't already have this in place. The idea that the capsule can survive a rocket break-up is not new: Challenger's crew cabin was in one piece (and probably still pressurised) all the way down.
Anyway, the main thing is they are going to implement this safety measure from now on, before manned flights start.
Re: And in other news
The Doom Bar in Cornwall has 600 wrecks in 1 km2. You'd think with that many it would be easy to stumble across a wreck there, but you won't find any. Sand is funny stuff.
He may well be right when he says that all normal people witnessing a nuke will become peaceniks, but it could have the opposite effect on psychopaths. And if those psychopaths happen to be government leaders (not exactly a far-fetched idea, I'm sure you'll agree) then the last thing we want to be doing is giving them nasty ideas.
I see the words @Beagle has posted above... but they don't necessarily prove there is a real human who typed those words. (part of me hopes there isn't, because science!)
Re: Current theories...
We know for sure that it has happened at least once. And if something can happen once, it can happen again.

Re: NH has phoned home
The most important question has been answered: an exogorth cannot catch a probe travelling at 16 km/s.
They'd better be very high-res pics, on account of dwarves being small.
Re: Dish mish
Wow, that page really is cool, thanks for the link! The Canberra DSN is about half an hour from me. Right now it is communicating with Spitzer, MAVEN & Mars Reconnaissance Orbiter (two from a single dish), and Mars Odyssey. One of the four dishes appears to be having a rest.
Re: Getting to the next star system at that speed is going to take a long time. :(
Does that include slowing the no-longer-a-toddler down so they stop at Alpha Centauri, or do they just zoom right past and continue onwards into the vast nothingness of space?
You can recall something for 20,000 years? I have trouble remembering what I had for breakfast!
He's not there yet, but there will be a documentary about him in October.
The Dwarf King
If we are forced to accept that it's a dwarf planet, and as we now know it is King, can we rename it to Durin? Or how about Goldemar?
Re: This good be good news or bad news.....
Have you seen where a lot of the uranium comes from?
Have you seen who has the biggest uranium reserves?
not sleeping, awake and hungry
It looks as though the shark has a nibble of the weight-bag which is holding the camera down.
"Prepped in advance" seems at odds with the "post-pub" brief.
And if you don't prep it in advance you have to wait half an hour for the uncooked rice to soak and another half an hour for the cooked rice to cool, by which time you've passed out in front of the telly.
Re: I vaguely remember reading somewhere...
I wonder how many commentards' heads explode when I mention less/fewer?
OK, here's a quick discussion. Where convection cells exist within a liquid you'll see polygonal (mostly tending towards hexagonal) surface temperature gradients, with the hotspots at the centre of each cell, cold lines at the boundaries of the cells, and fluid flowing from the central hotspots outwards towards the cold boundaries. See figure 6 on this page. So it's credible that a planet with a once-liquid water layer could freeze and some of that cell structure might still be visible (amazingly, some of the water may even still be liquid below the surface!).
The same process also occurs with thermals in our lower atmosphere, which is why glider pilots like to seek out cumulus (these clouds sit on top of a rising thermal in the middle of a convection cell) and avoid the "blue sink" of clear-sky areas between the cumulus. Sometimes a prevailing wind can cause the cumulus to form near-continuous lines, gliders can use these "cloud streets" to travel long distances.
Re: It's and it's
could've (the mother of could of)
ARGHHH!!! NOOOOO!!!!! Could've is the mother of could have.
Can I just say that the pic of the plane taking off is superb: propeller tip condensation trails, skis, and frikkin' rockets!
Re: Heat balance
I wish I could upvote the spectacularly refined chap so many more times than once: he has hit the nail on the head.
Re: Call me simple
It has not cleared its direct orbital neighbourhood of debris and is thus NOT a planet.
Neptune has not cleared Pluto from its orbit, so is Neptune not a planet?
The SpaceX and Boeing spacecraft designs are also more efficient, managing to cram in four astronauts per trip
The SpaceX Dragon 2 will be able to carry seven astronauts!
p.s. I wish it was still called DragonRider, that is a very cool name.
It's a long time since I've been to London, but I distinctly remember the night sky there as being orange.
Re: Er, no, you're NOT a vampire @ Volands right hand
Are you saying aspen is not poplar?
Re: Algorithmic trading
What you're describing there is using an algo to decide what to invest in. About as scary as people using Excel to analyse stock prices really.
Of course it would be daft to use Excel to... do anything, really. But isn't it true that picking stocks completely at random yields (on average) better results than picking stocks by thinking with our fleshy brains? I'm sure it would be a simple matter to write an algo to pick stocks randomly.
Plankton can be surprisingly big.
The definition of a plankter (the singular of plankton) is an organism in seawater which can't swim fast enough to make headway against the current. Put an average human in the Gulf Stream, that human is a plankter. North Pacific Right Whales live in the Pacific so you wouldn't ever find one in the Gulf Stream anyway - but if you did, it would be a 100 ton plankter.
Re: Couldn't Lewis Page write on something he understands?
He is the ultimate cherry-picker. On the upside, he provokes much debate.
If the mammoths have died out then it's because they are no longer best suited to their environment.
No, they died out because we stuck lots of spears in them. They'd survived all the previous warmer periods so their extinction wasn't environmental.
Re: PULL THE LEVEL IGOR! WUH HAHAHAHAHAHAHAAAAAAA!!!!
After you've pulled the level Igor, pull the sloping Igor too.
Re: Genuine question
> Late for what?
Late for its table booking at Milliways.
My suggestion: decouple Earth Time (based on rotation, so yes it changes gradually) from Astronomical Time (based on atomic vibration, so it doesn't change), and at the same time (!) adopt a better system for Astronomical Time: we should have a decimal system for counting Astronomical Time. Because decimal is just better: it is our standardised counting system*. After all, once we leave Earth and head out into the vast nothingness of space, GMT/UTC is irrelevant anyway. So let's take this opportunity to have a more scientific way of doing things for Astronomical Time, and stick with when the sun rises and sets for our normal terrestrial business.
*please don't get started on the factorial advantages of base 12**: we have 10 fingers and that's that.
**or binary, or base 60, or anything else. Seriously. Everyone is used to decimal. End of story.

You might get it in October, we get it in April ;-)
