U3-X Personal Mobility Prototype

in my mind i can see how the machine part would handle turning or pivoting... how do you convey that by leaning?
i just can't imagine how you would communicate to the 'chair' to turn.
also, a bunch of drunk people on these in a closed 'arena' would be awesome.

Gyroscopes and accelerometers: How do they work?

forced meme is forced.
re-read the statement.
(i was hoping there was more to getting the device to turn or pivot than simple friction.)


My bad, didn't really read your comment. There's an engadget clip on this, and to pivot you gotta use your feet.

Chinook pilot showing off

CrushBug says...

>> ^GeeSussFreeK:

I never really thought about it till now, but how does a chinook rotate without a tail rotor? It is all just differential rotor rotation? If so, does that mean you can turn around different axis' depending on which blade you use as the pivot?


"Tandem rotor designs achieve yaw by applying opposite left and right cyclic to each rotor, effectively pulling both ends of the helicopter in opposite directions."

Jimmy Kimmel Live: LOST Game

Sketch says...

Awesome!

Seriously though! What is up with the deus ex machina on LOST? I feel like the entire main story of the series could have been told in like 5 episodes, max! You are really going to introduce PIVOTAL characters at the beginning of your last season? Don't get me wrong, I'm still cautiously hopeful, but I have a feeling most of us are still in it just because we've already invested this much time into it.

"'Downfall' Hitler Parodies" Yanked by YouTube (Parody Talk Post)

dag says...

Comment hidden because you are ignoring dag. (show it anyway)

Although many of the parodies were funny, there were two things that I always disliked about them.

1. They kind of trivialise a great scene, a great performance and a great movie.

2. They make the assumption that most of the world hears the actual meaning of the audio as gobblty-gook.



To get perspective on the second point, imagine if there was a German craze to to take a pivotal scene from the The Hurt Locker and overlay humorous culturally relevant German subtitles - not so funny -perhaps even offensive to native English speakers? Perhaps.

Why math is dangerous...

GeeSussFreeK says...

One of my favorite quotes about math comes from that Einstein dude. Math and the sciences are pretty pivotal on how people see the world by and large. Which is why, when one of the greatest contributors to the shaping of that idea said this,

"As far as the laws of mathematics refer to reality, they are not certain, and as far as they are certain, they do not refer to reality."

I was taken back a little. Later, as I started to learn more and more, I came across the same type of though in my own education. Math can be perfectly consistent when talking about itself, but when you start to translate that over to the real world you have to consider you are mapping one system onto another and some things might be lost in translation. For example, calculus is beautiful, but does it actually answer the question how finite objects move through infinitely divisible space in a time that is finite? Drat you maths! You bring us beautiful proofs and no understanding!

(ohh hey maths, I know I was just talking some mess, but can you help me see if the tensile strength of this cable is enough to support this bridge...hey thanks man, I'll buy you a drink...(as x tends to infinity..eheheh sucker))

Embrace Life’s Writer/Director Daniel Cox: “It was central to the development of the project that we root the concept of wearing a seat belt firmly in the family domain, and create the advert so that it could be viewed by anyone of any age. Children are so important as opinion formers within their family that we felt it imperative to have a child take a pivotal role in relaying our message.”
“One key aspect to the storytelling is that we developed Embrace Life to be non-language specific, so that the message wouldn’t become lost when viewed by visitors to, or residents of, the UK where English might not be their first language.”

The double pendulum gives an example of chaotic motion

deathcow says...

> and the waves that we see as atoms will never be the same ever again

I doubt quantum variations are a major player here. Air motion, temperature? Maybe to some degree. Temperature of the metal in the axis of the pivots? (Resulting in differing dimensions and clearances) Probably.

Difficulty of setting up the exact same starting dimensions, temperatures, motions... a huge YES

Naomi Wolf on "Fake Activism"

longde says...

Iran has irrevocably changed due to their protests. Political and historical change does not occur like it is presented in history books, with stark changes sweeping through at pivotal events. It happens at the individual level, incrementally. One day you wake up and the world is very different than it was a few years ago.

The Iranians, whose population is dominated by youth, has just passed verdict on where they want there country to go. A sentiment that heretofore was whispered in barbershops or over coffee, has been, en masse, confirmed. It makes a huge difference to know that it's not just you.

And it's not just Iran, real protests happen all over the world, all the time. And they do foment change, just nothing you will see on CNN or Fox.

So why's everyone down on the Matrix trilogy? (Scifi Talk Post)

Drax says...

For me parts of the sequels seemed very poorly executed. Compounding that was it was impossible to tell in advance after only seeing the second movie. For instance the Merovingian seemed like such an interesting and mysterious character in the second film, but he amounted to nothing interesting by the end of the third.

Mentions of ghosts and vampires (or was it werewolves) by the oracle, having no real part to play in the movies.

Persephone's just one kiss scene in part 2, it seemed like such a pivotal and dramatic scene yet it didn't amount to anything really.

There's just all these elements.. especially in the second movie that don't play out. That goes for the conclusion of the series itself.

Then came the ultimate answer to all of this.. the MMO that was made in corelation with the developers of the film. The Merovingian becomes a faction in the game. I believe the whole ghosts and werewolves thing becomes relevant in the game (I haven't played it). The resetting of the world.. well.. you need that in place if you want to have a game taking place in the world. I seriously think it's their plans for the MMO that weakened the over all plot of Matrix 2 and 3, though part 2 is a VERY fun action movie.

Another big element... there's barely any gun fights in the sequels. I know The One has no use for guns, nor are they effective against him, but come on... they could have had one mega gun fight somewhere in the story. There's a short shoot out in the third movie at least, that's actually one of it's redeeming qualities for me.

The other point someone made about the part 2 and 3 answering so many questions about the world is relevant too. They also seriously fucked up the setting when Neo used his powers outside of the matrix. That's when the tightly constructed universe of the first became a notch closer to a generic super-hero movie.

...nothing in the Matrix movies is as bad as what Indiana Jones 4 did for THAT series however. /derail >.<
