Is Reality A Mathematical Structure?

Gravity Glue 2014- Rock Balancing Video

artician says...

He's got a great eye for form. That structure he spent time showing between ~4:16-4:28 was impressive for its implied horizon and .. blah blah blah, I just liked it.

The Secrets of Quantum Physics - Einstein's Nightmare

vil says...

Exactly. He got all the girls. Watch him and learn.

If this arbitrary value comes out more than 2 Einstein was wrong. And the answer is.... 2.5 woohoooo! Anything practical on the horizon?

Also strings + entanglement = Flying Spaghetti Monster confirmed.

Watch Feynman. He was the true genius of the 20th century.

Unbelievable wingsuit ride!

Bruti79 says...

Is there a name for the phenomena of when the horizon looks like he's flying level to the ground, and then when he looks back off the mountain, it looks like he's shooting down a mountain again?

Very cool video.

Elite: Dangerous - Gravitational lensing around a black hole

AeroMechanical says...

Well, nobody has ever seen a black hole so no idea. On the other hand, if there was no other matter around it, that's probably about what it would look like. Given the apparent size of the event horizon, though (the black dot), I think maybe if anything the lensing effect is exaggerated. The developers claim to be going for realism though, at least in the presentation of the galaxy, so they probably did work it out properly.

What also makes me vomit is how it was eventually presented as some kind of humanitarian gesture of offering up a new technology to people, expanding our horizons thanks to this philanthropy, woe be unto the wheel for we give you all the gift of ... electrodynamic levitation, which has been around since the early 1900s. It's just more cost effective and this douchebag knocked one together.

I could make one.. the only downside is where and how to store the energy required to run it.

Tomorrowland (new film from Brad Bird)

Nixie: Wearable Camera That Can Fly

My_design says...

Yeah there are slap bands out there, but they don't work like this is presented to work. The arms would have to bend in multiple dimensions, and then straighten out and be able to provide a stable flying platform. The closest thing I think of for doing something like that is the "bendy" character toys where the metal wire is co-molded inside the body. That is a very heavy solution.
I misspoke on the 2" square, it is 2" x 2", so 4" square. I'm not sure that I agree that theirs is 6" x 3", but even if it is that would mean that the prop size would have to be about 1.25" and that doesn't work for a 6" x 3" vehicle. There isn't enough thrust and the motors at that size don't provide enough RPM's for that kind of weight.
On the electronic side, they show it connecting to a smart phone with video feedback. That means you have to have bluetooth at least, or a 5.4ghz video system if you want more than 30' range. or it has to have a Wifi TX on it. All of those thing require power. Sure it could analyze the video signal to determine subject matter, and provide guidance but you have some very serious issues there. If you do it on board it requires some processor power (More drain), if you do it on the smart phone app it will create lag.
Your phone has over 1,000 mAh in it (1440 in Iphone 5), that is a TON (4-10x) more than what this thing would have. Battery technology may be a big research project right now, but there isn't anything on the horizon that will get them to where they need to be. Most of the tech research is in sub 1C rated batteries for things like full size cars. Something like this needs a 10C rating minimum if not a 20C rating. Unfortunately most of the upcoming technology can not handle drains that fast. Things tend to go "Boom!". When you do something small, and even 6" x 3" is small, you have very serious power vs weight issues. It all comes down to issues of power density, and nothing exists today that will give it to them as they would need..

So right now these guys need to figure out:
1) A new light weight material that can lock rigid but also bend as needed in multiple directions.
2) A new battery technology that allows them to get the power they need, for a 6 axis gyro, 4 motors, control board,a RX, a HD camera and some sort of VTX while reducing weight. How long it powers all of that would be open, but if it is under 10 minutes I think people would be a little disgruntled. Right now people are wanting the video quads to get about 30-45 minutes of flight time on the 5200+mAh batteries.
3) Write code that allows them to analyze video in real time so as to provide object tracking and avoidance without lag while capable of running on a smartphone. It would also need to return to home when the battery runs low. That would be a little tricky on a cliff face, or if you are riding a bike through a forest. Another issue is that they tilt the camera down, they don't say if this is actuated, or done by hand, but it could lead to serious issues with programming object avoidance if you can't see anything above you.
4) Since they show the image as HD on the phone screen, they would also need to come up with a new way to broadcast HD video wirelessly. Right now that system costs $40K and is rather large.

All in all it is a dream product that people are going to get suckered into funding it. Some tech may come out of it that could be monetized, but I don't see the item coming out in this format, at least not in the next 3-5 years. You'd be better off going with AirDog.

Well, perhaps with currently available public domain parts, it's not possible. That doesn't mean it's completely impossible.
The flexible frame might be hard, but there ARE already wristbands that un-bend to make a flat device, they've been around for decades, I recall seeing one in the 90's. Making it support flight might be hard, but not impossible, especially with the small forces this thing provides.
You say there are already 2" square quads out there, this was closer to 18"square(6"X3"), so the 'it's just too small' argument falls flat.
Battery time might be a factor, but a 5 min video is pretty good for now, plenty to prove the concept. Also, battery life is increasing fast.
The camera and GPS in a phone hardly uses any battery power too. These tiny devices are really not hungry enough to make them a power drain problem, at worst they might limit flight time slightly. Also, there's no GPS needed really, it could operate by keeping the subject in frame at approximately the same distance...then it could just follow you through the trees, using the image to avoid obstacles. It would take some computing power, but not an outrageous amount. Perhaps it's paired with a cell phone to do the computing? That part wouldn't be hard.
Again, because the tech isn't available on the market today (and I'm not at all sure that's correct) doesn't mean the tech isn't available to some, or creatable by intelligent people. I just don't see this as that far away.

Crazy Guy Runs Into Outback Tornado To Take Selfie

artician says...

This is fun. Looking at the reflection, and knowing pretty intimately how reflective surfaces work, it still seems questionably-real. At 0:43-0:44, the reflective angle shows a large strip of earth-tone well above the horizon line, and also above the reflective bend of the door-handle curvature meaning it's not an artifact of the surface angle. The large strip of earth-colored element that's splitting the mans reflection up the middle in the same frame very well could be an angular reflective artifact, or just the reflection of a low-angle shot between his legs. (just to cut off any naysayers along those lines).
It is as clear a sky as glass despite the 'willy willy', and that seems supported by the reflection. I actually think this might be legitimate. If it's not... Well fucking-A, I'll go back to school if it's not.

The willy willy looks just like that recent one from a garden in Japan. I'll add it as a related tag later if I can find it.

[spoiler]It's certainly quite well done, particularly the first half. If you want to know for sure though, check out the reflection in the door handle around the 44s mark, and also the shadows on the ground just prior to that.[/spoiler]

Yeah, must be Helsinki or near there, long day for being the darkest of winter. We get about five hours of "light" in Kuopio on the shortest day, barely gets over the horizon. Compare that to over 20 hours of sunshine, and very bright 3+ hours on the brightest day. And people wonder why I have seasonal depression.

//edit

Hmm this was supposed to be a comment on the time lapse video...oh well

This must be somewhere in the south.. Where I used to live, it was even more drastic! I do miss the summers in Oulu, when it never got dark during mid-summer time..

One Hair-Raising Bike Ride - 1st person view

LiquidDrift says...

By the end of the video, my head was pointed upwards because I was unconsciously willing the camera to look up - the horizon is tantalizingly out of the frame for most of the vid, so annoying! What a ride though.

Babymetal: J-pop-metal crossover

SPEAK ENGLISH OR DIE

Yellow Machinegun anyone? They don't always wear the school girl thing, but the first album I owned of theirs featured them wearing schoolgirl outfits and SCREAMING!

This ain't new or news. Lamer, poppier version of something that's been around for more than 20 years.

My wife works in fashion, designs for Urban Outfitters, PacSun, Roxy, Quicksilver, etc. etc. Your girlfriend or wife probably owns either a handbag or an article of clothing designed by her. The styles and trends that are in take us all the way back to Cramps/Misfits/Rocky Horror fashion sense, amalgamated with '90s nihilism and modern pop (often hip hop, but in the case here, J Pop) trends.

Nothing new is happening and that makes it SOOOOOO much easier to anticipate the trends and succeed in making people think something "new" is on the horizon. lol

Oh no, how ever shall he cope with the slings and arrows of the likes of me?

Look! on the horizon!
It's Saint Ching to Justins rescue, and he's definitely doing it out of concern for the poor little rich kid and not simply for the sake of being a contrarian.
