Cruise ship construction timelapse (bonus light show)

RFlagg says...

I was going to ask what is the advantage of block building over regular building in place (though I'm sure I've heard the explanation via Discovery Channel, History Channel or National Geographic Channel special on modern mega ship building) but found something that explained it well enough: http://www.marineinsight.com/naval-architecture/advantages-of-advanced-outfitting-shipbuilding/. So now just looking for a further ELI5 confirmation/explanation.

The Moon: Crash Course Astronomy

MilkmanDan says...

Crash Course is awesome. Continuing in the tradition of PBS educational programming, Discovery (before it was all about Bounty Hunters etc.), and History (before it was nonsense about aliens), etc.

Nearly 10 minutes of information that was almost entirely new to me, very entertaining, and *felt* like I was only watching for 2-3 minutes. These guys know their craft!

I want to eat your child

AeroMechanical says...

That's why those Indian folks wear a mask on the back of their head when they're out in tiger country. Ah, I learned that on the Discovery Channel back before it was all military and disaster porn (oh, and shark week).

Vantablack can make a flat disk of aluminium float on water

newtboy says...

I was not talking about Vantablack in my comments. I was talking about other, older hydrophobic coatings.

Also, I'm fairly sure they bond the nanotubes with something to make them stick and stay in place. Pure nanotubes are just a powder, they would not act like paint. Nanotubes are not a new discovery and have been used in consumer products already, mostly electronics, google it.

I really doubt this would be considered safe enough to put into something for consumer production like a cell phone. It's made of carbon nanotubes. Those get into the air, and it's very, very toxic to breathe. It is like needles stabbing and slicing through your cellular membranes. There are some real concerns about the long-term safety of CNT. I would feel very unsafe having to work with it every day.

Apparently The Greatest Airbag Crisis In History Is Upon Us

newtboy says...

Totally true....but in all honesty, my car is so rusted that the entire body is really a crumple zone at this point, but not an engineered crumple zone.
The bronco is much taller/higher than the discovery in that vid, and much tougher, with 500%-1000% more bumper, but it only has lap belts, not even a shoulder strap, so in that situation if I don't drive up over them I'll probably take a steering wheel through the chest.
EDIT:The Jeep is even higher, so more likely to drive over anything, with no bumper, just protruding front tires to bounce off or pop, full 2.5" roll cage, and four point seat belts attached to the cage. It's safer than any normal car made today thanks to the add ons.

BUT, remember, the crumple zones work to decelerate BOTH cars in an accident, not just the car with the crumple zone, so as long as the car I hit has them, I'll be OK....maybe. My CAR will certainly survive better than the newer car, at least. ;-)

Structural failure isn't the only risk. The point of modern safety features is to reduce the impact of the crash on the occupants. If you crash an army tank into a large tree at high speed, the tank itself is likely to be fine but the occupants probably won't. In your case, whether your car is better or worse than the average modern car in a crash is probably "it depends".

How does your car compare to the Discovery in http://videosift.com/video/Crash-tests-SUV-vs-Minivan-Which-one-does-better ?

Sure, but I drive a Bronco with a full roll cage....not a bel air. I would crush that bel air too, and the Malibu. Bronco's are tough enough to do both, they have a thick full tube frame and heavy metal body, not a weakened C-channel or less covered in plastic. Mine has a >300lb industrial steel bumper as well.
My other car is a 73 CJ-5, also with full roll cage and with 4 point seat belts, that is tall enough to drive right over both of those cars or, if not, turn them into convertibles. ;-)

So yeah, I still think I'll do WAY better in a crash than an average new car.

Extreme up-close video of tornado near Wray, CO

Esoog says...

Thats Reed Timmer. He was one of the 'stars' of the Discovery show, Storm Chasers. He does a LOT of tornado research using doppler, probes, uav's, etc. He has a Ph.D. in meteorology. Very interesting guy and has done a lot for progressing storm safety and early warning systems.

Steam Powered Giraffe - Honeybee

Stormsinger says...

Wow! That's just outstanding.

The sound (and quirkiness) rather remind me of an acoustic 10cc. I'm off to search up some more of their pieces. Thanks for a great discovery!

An historian's take on what went wrong with Islam

vil says...

It wasnt al-Ghazalis fault that muslim society adopted his idea that math is evil and made it doctrine. He was long gone by the 16th century.

It was the fault of the muslim religous authorities, but you cant say that in one sentence, if you are a muslim, even today. You have to go on and on for half an hour, naming all the muslim famous scientists, just like you would have to name all the famous russian scientists if you were a russian professor talking to a russian audience.

Even if 17th century muslim society had a Newton or Leibniz or Kopernik or Kepler and they managed to publish, what impact would their discoveries have had if they could not be used in practice for religious reasons?

It hardly matters who invented the lightbulb, if you have to keep using candles for religious reasons.

Atheist Social Justice Warrior vs Christian

Shepppard says...

It just took me 16 minutes of watching an inspirational video about the accidental discovery or re-growing skin and how it's helping children with huge amounts of burn coverage on their body to make me feel good about humanity.

It took 18 seconds of this video to make me forget that feeling.

Kudos.

How to DMT

newtboy says...

It would be astonishing to me to find that many people had developed advances in technology thanks to this drug, but for some reason 100% of them keep quiet about it. As you mentioned, other illicit drugs have been publicly given credit for inspiring useful discoveries. Given that, why might this one drug be considered something to hide so universally (edit: by those inventors), especially if it's potential usefulness is so great?
Art is a different thing, and it often benefits more from injurious experiences rather than beneficial ones, so it's not a good measure of a drugs overall merit.

I'm sure there are people out there that have come up with software/technology from the influence of DMT, they just haven't come forth. I'd say that it has recognizably influenced ideas & thought - especially in the area of frequencies, energy, reality is a hologram sort of shit like that because the DMT experience is the frequency, mandala portal experience, lol! It's certainly influenced great art, look at Alex Grey. I've learned a lot of things that seem to not apply to this reality and the last time I took it, the only thing I learned was "GOOGLE", lol.

LSD on the otherhand has definitely influenced technology and science. My favorite LSD thought experiment become reality was Francis Crick's discovery of the DNA strand while on it.

"I'm still waiting for the insightful invention someone comes up with after one of these amazing 'conversations' with non-human beings. If this drug really did what those into it claim, you would expect most users to be incredible 'outside the box' inventors advancing science in ways normal people would never consider...but I have not heard of even a single instance of that kind of useful insight coming from DMT."

The best way to reduce risk from taking, or getting caught with DMT is to not do it.

Thinking of you. Miss your bon mots and perfect English.

My cousin just helped an ailing former POW from WWII write his memoirs. I thought of you when he told of crossing a bridge with a huge unexploded bomb wedged into it.

She did some research to pad out his few memories, and added a story about unexploded ordinance being found in... Frankfurt? During construction?

I can't remember the details, but I do know that when it first happened you sent me a link to the discovery of the bomb.

Hope all is well.
