I understand why this is confusing as hell;

http://science.kennesaw.edu/~jdirnber/InvertZoo/LecIntro/TreeTime.jpg

... here is a relatively straight-forward 'evolutionary tree' cartoon,... the biggest thing to note is the Time axis... you have to trace the lines to see where species diverge and then look around to see if that line split happens before other line splits with respect to the Time direction.

Even in this simple diagram, you have to look at it for a minute to realize that reptiles, birds and most of the dinosaurs we think of split off from what became mammals, then reptiles split off from that group, then some dinos split off, then birds... So this is to illustrate that the split between what became mammals is farther back in time than the split separating birds and most dinos, and birds and reptiles. So this illustration really functions like a family tree, showing relationships with time and allow you to pick out that birds are closely related to dinosaurs, and that we have to go pretty far back to see where animals diverged into what became mammals and what became reptile/bird/dinosaurs.

If you're interested you should look for bigger ones trees,... when you start including plants, bacteria, archaebacteria, etc.... stuff gets pretty wild because you're reaching the edge of the science... and the complex smaller trees that just cover one group of critters can be really interesting to see... so much variety.

Oh, last note for transparency; they generally make these 'family trees' by researching comparative anatomy and tons of fossils, but have been using DNA to produce new and correct old 'phylogenetic trees' for 20 or 30 years now.

Same logic: What are we then?

Mammals - which birds aren't and dinosaurs weren't.

Yes ok, but Mammals are as much Reptile as Bird are Dinosaur.

Look at you, being all smart about history and stuff!

In reply to this comment by radx:
It was posted on the Axis History forums sometime last year. If anyone wants to read up on the incident, the sub is a Balao-class, the USS Pintado, and the crashed B29 was the "City of Galveston".

It's a shape that, because it "wobbles" around it's centre axis, rather than rotating around its centre axis like a wheel, it can present a consistent cross sectional width between two parallel planes. In reality, there are three points it rotates around at any particular time, depending on what point it's at.

Think of it as 3 pie shapes. It rotates on a point at the book, and when it finishes it's arc on the table, THAT becomes the new pivot, and the book travels on the arc, then the table, then the book... etc.

What's neat is you can do this with any odd-sided polygon. It won't work on even numbers.

Yeah, I'm deleting that last part as there's too many conditions for that to be simple.

Not sure if this counts as a dupe... A newer live performance, with new songs integrated into this mix... Also tough because it seems like a better performance. No, nevermind, not a dupe, too much new material.

i'm not trying to open a can of worms, or threaten anyone's "beliefs". but this appears to be happening.

Yeah, and um, from THAT article: "The Earth's poles are changing constantly... "
You really liked the movie 2012 didn't you?
sigh

sigh.
that article is just a quick google to show that even mainstream media has noticed it.
the gov goes to great lengths to not alarm it's workforce. a steady diet of charlie sheen. sigh

all theories can be conspiracy theories if you wish to label them as that. and you're trolling. fuck you.

I am so NOT trolling, I'm just sick of people like you that see some natural disasters and then start saying 'THERE'S SO MANY MORE NOW! THE WORLD IS ENDING!'
Really?
Where's the increase in earthquakes? http://www.johnstonsarchive.net/other/quake1.html
Where? Take a look at the numbers and tell me you're seeing an increase over the last 30 years, because you aren't. Because there hasn't been, because it's bullshit.
Stop using just your perception that 'gee, there seems to have been a lot of earthquakes' as an empirical measurement, look at the ACTUAL FIGURES before you start saying such things. And stop relying SOLEY on nut job websites for all your 'facts'

fine. stop using comments designed to create an emotional response.
your figures are great, and show a marked increase in seismic activity, especially in the last 5 years.
what i'm saying that if you increase the total mass of the worlds oceans, and reduce mass at the axis of rotation, coupled with water current patterns that will concentrate these masses differently than what has occurred in the last, say, 1 million years, we may very well be seeing enough change to affect very unstable plate movements that occur on a fairly consistent basis.
this isn't a 2012 conspiracy. and the world isn't ending. and maybe i am crazy. i sincerely hope i am.
but we are just starting to understand how fragile our ecosystem is, and how dependent we are on the stasis of it....and that underestimating such fragility can come at a very high cost.
look at what we are doing to the rest of the planet, the rest of the ecosystem. why is it so inconceivable that we may also be affecting something that is constantly teetering as it is?


and what further alarms me is that with a system that has taken a few billion years to find a relatively stable equilibrium, it's adaptation to change also takes time, on a different scale than we're used to (a plantetary time-frame), meaning we may be now just seeing the effects of our changes to the climate, and meaning that these adaptations could continue well after we've ceased mucking about.

DonanFear's 1st rule of graphs: If your axis doesn't start at 0 then you're probably full of shit.
Not that CO2 isn't increasing, because it is, but exaggerating like that makes you look desperate. The music doesn't help.

Wow. Even on the sift you're debating distance from the sun. Distance from the sun, whether it results from the tilt of the earth's axis (the north pole is less than 5000km closer to the sun in summer) or the eccentricity of the earth's elliptical orbit (the earth itself is 5 million km closer to the sun in January than July), is immaterial. The tilt of the axis results in variations in the angle of incidence at which the sun's energy strikes the earth resulting in variations in the intensity of that energy on any given point on the earth's surface. It also affects the thickness of the amount of atmosphere that the sun's energy must pass through. The tilt also varies the length of the day. More daytime hours in a 24 hour period means more energy absorbed from the sun, more nighttime hours means more energy radiated back into space.

That being said I don't find it particularly disturbing that a bunch of arts grads, even from Harvard, might give these answers. I asked this question of my two daughters. The artist talked about distance from the sun and the MoSc in molecular genetics talked about axial tilt.

(..looking up perihillion, precession, & aphelion in the dictionary)..

I concur!!

Right, SpaceDude - I fell into the trap of thinking in a hemisphere centric way. Perihelion will bring the southern hemisphere closer to the sun during the southern summer, but aphelion will put the northern hemisphere further away during its summer. I'm guessing it's just coincidence that perihelion and aphelion occur very close to the solstices. Precession of the earth's axis would change that over time, right?

Fair enough, longde. Their stated answers were wrong. I'd argue the editing helped that, but it's not really worth it. In any case, if this is grade school stuff, why would Harvard (or any college) professors be wasting their time teaching it to students. Wouldn't they assume their students have basic science knowledge? I think this falls under the "use it or lose it" principle. I studied geometry proofs in high school, but never really used it since. If someone walked up to me with a camera and asked me to give a proof for the equivalence of alternate interior angles, I'd probably be stumped too.

A trailer so well considered and constructed surely could not be made by a team of people behind a bad game.
Surely?


Actually, the trailer was done by Scottish animation studio Axis Animation. Story here. The game however will be developed by Techland, a polish developer best known for the Call of Juarez series.

It's very unusual for CG trailers to be made by the same people who make games these days; generally they are contracted out by the publisher to other companies that specialize in high quality CG. For example, Blur Studio does brilliant work, and was responsible for the trailers for games like Mass Effect 3, Bioshock Infinite, Arkham City, Fable III, Warhammer online, ect. Players don't generally know this, because developers take no pains to credit them.

Maybe some one should throw Axis Animation and Techland into the tags.

A 4th Dimension roller coaster is a type of steel roller coaster whereby riders are rotated independently of the orientation of the track, generally about a horizontal axis that is perpendicular to the track.

David Frum was a speechwriter for G.W.Bush and phrased 'the axis of evil' narrative. His credibility as his speeches should be a fiction.
