Video by Brady Haran - Věda a technologie
this is amazing.... I must sound like a broken record because I am repeating this in almost every video but things shown to me on this channel are simply AMAZING!!
***** that's okay - that is the kind of broken record we like!
+DeepSkyVideos All your channels are amazing......amazing......amazing......amazing......
maybe you're just a bot that writes "this is amazing" on every single video on youtube :P
Why u spam? D:
Couldn't possibly have found a better guide, this guy knows his shit on all aspects.
I like the term "anti-breadloaf".
That would be a "bread pan".
@@christopherschrader3067 this is extra funny for hispanics because "pan" literally means "bread" in spanish
Once again I'm compelled to thank you for making these videos, Brady! I love to listen to research scientists speak about their fields of study when the audience is just a curious subset of the public at large. Bonuses in this video included a conversation with a handsome alpaca and my new favorite word: 'anti-breadloaf'.
kkira22 we appreciate your comment
I can't believe how quiet those antennae are when they move.
The awesomeness is unquantifiable.
Awesome Brady! Nice to see more DeepSkyVideos coming, this is by far my favourite channel on YT :)
Awesome, thanks Brady
i'm always amazed at how much the Atacama desert resembles my imaginary Mars, i hope i'll be able to go there some day
ALMA is by far one of the craziest (meta) machines I've ever seen.Thank you for showing this.
Fantastic Brady!!!
That was an amazing video Brady. Nice work!
Thanks Brady for another amazing video.
That was super awesome. So glad that this kindve thing gets funding.
Nice Sir .
Thank You Brady .
THANK YOU DENIS .
absolutely brilliant. Thanks
Really liked the humor on this one (also the telescopes were pretty cool obviously)
Thanks, Brady! Looking forward to seeing Part 2.
Brilliant explanation of using Fourier transforms , is of course is " Aperture synthesis". Developed by Joseph Fourier at the time of Napoleon is one of the most useful tool to understand reality.
G's those things can move a hell of a lot faster than one would expect
Teddy Boragina I know!!!!
Thank you so much for posting this!! So cool to see this all in action. :)
Excellent video! Thank you for the tour.
Best video ever. Never got a proper explanation before. Now I finally understand.
Amazing array
that is some of the most impressive use of science and engineering I have seen.
what and who are people fighting wars for ? lets work together and head off to the stars to ensure a future for humanity.
Awesome. Although I feel short of breath just watching you guys.
Absolutely amazing video. Late to the party, but happy I came!
A fascinating array of structures.
Very nice video! Thx for sharing!
just awesome. Thanks.
10:45 You can really see the monstrous scale of these things.
Absolutely amazing!
The view looking out past the snow to the array of telescopes looked surreal. It looked like you were on some extraterrestrial basestation.
Another super cool video! Thanks.
This channel is full of awesomeness!
Did Pete do the pretty night pictures/time-laps-video?
Thank you so much for bringing me to a place I can not physically visit. What an amazing place.
Enthralling! Thank you Brady, bless you!
Thanks for that. That was more interesting than their own clips for public:)
Absolutly wonderful, thanks.
MerciaDragon you're welcome
That's so cool!
This was really interesting! I had no idea about the amount of work and engineering that is required to keep things running. Really awesome!
These arrays are so cool :D
wow this is awesome!
Fantastic - pls turn your cam not so fast ...
Could you recommend literature regarding the interferometer and the method of getting a picture for non-specialists...?
Brady, I bet the Fourier analysis they conduct would make an awesome numberphile or even computerphile video.
The pattern of the telescope pads looks very mathematical.
Would make a greate numberphile video to talk to the people who placed them.
Awesome.
So so cool! And breath taking scenery! (No pun intended)
Great video. Thanks for that. Well done to film at that altitude. I've been to 4800m and I was flat out to drinking chai and sitting still.
Awesome video! I didn't know that the antennas were actually moved around the place.
Just got back from that area! Funny coincidence to think you may have been filming this the same time I was there.
I wonder how much one of those transporters costs. They're probably custom made even.
tjpld They are custom made, indeed: www.scheuerle.de/en/products/new-vehicles/special-transporters/antenna-transporter.html
Wow, this looks so awesome! :D
There is a lot of self-admiration of the blogger and very little astronomy itself.
Now, this is my kind of mega construction!
I recently found out about LOFAR. It's the largest radio telescope in the world and it's based in Europe. It has one station in southern England and it's "core" is based in The Netherlands.
Have you ever thought about visiting LOFAR, Brady? I'd love to see some footage of the arrays from you.
Plus, it's a lot closer to home ;).
Cool video, great stuff thanks for sharing this, mind boggling but I don't mind.
Any chance on you guys getting a tour of the GBT?
Wow it's amazing
this is awesome ! Great video, it look like science fiction, so cool !
What's with the different "models" of the antenna? Some look different to each other. Do some specialize in more short range while some specialize in more long range?
Can normal people visit ALMA? I mean, people that are not working on it.
More like L(L)AMA, am I right?
John Titor looks like a Guanako
Don't bully the llamas, they can identify as anything they want. Who're you to judge?
John Titor TIL Guanacos and vicuñas live in the wild, while alpacas - as well as llamas - exist only as domesticated animals. - wikipedia
Wikapeada lies! I did a report and some are not desmecated! :-P
Alex Fielder Well, this particular paragraph was cited from a book named Wonders of Llamas by Roger Perry, page 7. I guess if they ran away you might find them in the wild. Dingos used to be domesticated too.
I always feel like I'm looking at what Mars will be like when I see these videos. Such a stark desolate landscape with really amazing structures and technology.
Wow, what a landscape! and a technological wonder,
Brady, you have a dust spec on camera sensor @ 12:05 o'clock. Check at 1:29.
Your camera work is great! What kind of camera is it?
Brady, we should get some videos about Pluto for the flyby
Love the reference to Lulu.
Any chance you'll be visiting the various facilities which are being used to develop technologies for the Square Kilometre Array?
I'm interested in hearing about the low-frequency ones like LOFAR in The Netherlands and the Murchison Widefield Array in Western Australia.
Can Nik do a review on the vixen polarie?
Keep banging those rocks together people, you're doing a fine job.
amazing stuff here.
I imagine that when he said they are limited by the dish size he is talking about a moving one? (hint hint - when are you doing one on Arecibo?)
and a second question - other radio telescopes usually do not need such high altitudes, I guess this one does due to the wave length it it designed to receive?
Do cars need any special equipment or treatment to operate at those altitudes?
Quick question, at 5:55 three "rows" of dishes can be seen, all built a bit different.
Could you elaborate on those differences or is it simply due to the diameter of the dishes?
Thank you for all the videos and great insight.
dat artsy nature shot doe
Awesome :P
YAAAY SIENCE..... where is my jetpack? :D
Could you please upload all your videos with the same audio level?
could we build an even larger array in space someplace? with a radius of many km or even hundreds or thousands of km?
That is seriously cool, I'd love to go there. Much wow, very jealous.
Nerdgasems all around! This is great technology!!
ALMA Rocks!
Damn, these videos make me so proud to live close to there
Narrated by Darth Vader :D
What is the font that Brady uses in all of his videos?
Forget pyramids. This is a new wonder!
I know it's not exactly a science issue per se, but I'd love to see a video on how you finance a project like this!! It's absolutely remarkable what they were able to build here :)
Is 02 pumped in to the buildings ?
Those antennas move QUICK!
2:33 Hypoxia kickin' in real hard :-D
This is from your last trip to Chile or a new one?
The transporters are so very cool. They look like have just rolled out of a pod dropped from Thunderbird 2 :)
so cooool
Cool ballet of dishes :-D
I was not aware that the wavelengths being observed in radio astronomy were affected by atmosphere.
Excellent explanation of Fourier’s Transform being outdoors 5,000 m high. However, the plot shown (Power vs time) 13:15 is raw data and not a frequency spectrum (Power vs freq.) which should be the Fourier transform of such time waveform, calculated by the Correlator through an algorithm called Fast Fourier Transform, useful for scientific purposes, as said.
It looks like a mine field of telescopes!
Do the cars or the machinery they use to move the dishes around struggle at all to work because there's little oxygen?
If it is possible to combine images from many large telescopes, why not use a huge number of small ones in array?
Are there any technical disadvantages to use many cheaper units?
ako You need even more computing power to combine the data. A large part is also knowing exactly how the telescopes are positioned compared to eachother. Plus a larger surface area means you can take the same image in less time.
I'm not an expert though. These are just the things that I think are true based on the mathematics they are using. Especially the positioning is extremely important. There's a good reason why the guy emphasized the engineering challenges for the pads.
didn't know altitude was as important for radio telescopes as optical ones. one can only surmise, if it weren't supremely important they wouldn't bother to put them up there.
i learned something new. thanks brady et al.
the name should have tipped me off but it's the Millimeter/submillimeter wavelengths which get absorbed/scatter in the atmosphere why it's so important these are at altitude?
It's also the remote location, to help escape radio interference from technology, found where humans live and work.
