I like how physics girl always find another physics girl to talk about physics.
That's kindof part of the point of her show. One of the goals of her show is to show women other women in STEM.
Jealous much?
And she still makes things like this 6:44 at least the left one is really into it.
Not like she isn't smart... She just isn't THAT smart like the girl on left about physics

I love the enthusiasm this young lady comes across with-- you just just to smile through all her videos-- can you imagine how hard it must have been to be her physics teacher. Looking at you with those eyes, one million urgent questions every lesson :)
You want to find a life partner who looks at You the way Diana looks at that mirror!
Especially the initial glimpse @ 01:58
most women i have known look at mirrors that way
Isn't she ultimately looking at herself in the mirror.
Yeah, all that and brains too. I found one 22 years ago and married her.
@@gl1500ctv I found one 7 years ago and things didn't work out...at the time. So we're giving it another go 🤷♂️😁
"We're going to collect more data in the first year than had ever been collected with telescopes." ..... What? That statement is a lot to take in.
Considering that the entire competition is a handful of telescopes with decades-old hardware and what's effectively a bunch of amateurs making a handful observations in a night, it's not difficult to generate more data than all of them combined.
Just boasting a bit.
I mean, they do need to sell the project to get the funds and they have to stick to their guns afterward.
When your CCD has orders of magnitude more pixels than anything possible up til then, and you extrapolate for 10 years of uninterrupted survey going automatically. The thing is, that it is a survey: they are not looking for anything specific at that stage, just make a better map of everything. - Would have been interesting to know the amount of hard drives they will need for that... (- now I imagine a big “Elite Dangerous” update in 10 years^^ - or astronomers using “Google Universe” like tourists use “Google Earth / Maps”)
When you look at something like the Hubble and all of the incredible images it has produced, it is pretty impressive to think they are going to surpass everything it has ever done, in like a few months.
Michel Schweinsberg well it doesn’t “surpass everything” - the claim was for the amount of data, not the magnification. Telescopes are built for special purposes, and this one is a survey telescope - looking at larger patches of sky regularly (picturing the whole southern hemisphere every 3 days for 10 years iirc). - edit: deleted my wrong statement as I stand corrected.
I wish you talked more about how the lenses are built and how they are going to overcome distortions from lens weights.
She doesn't know how to say words
It’s very thick
www.lsst.org/about/tel-site/mirror #thetruthisoutthere also #lookingforcougars ... never thought about lens weight distortion, but I am familiar with term (not so much the physics of) "gravitational lensing"?
Yes, I am wondering too. apart from the potential of the weight to warp and change the surface area, I am curious about the pressures under the amount of weight potentially changing the density of the lens material (Gradients) sufficiently to create distortions. Uniform distribution of the pressure would be required and needed to be accounted for prior to creating the dimensions for the surface area.
Just a bus driver myself, not sure if what I said is at all important.
Maybe they can do that in another video.
"The cover is sliding along vertical poles, so that it doesn't swing and accidentally bump the lenses"

Love the energy of the girl you interviewed! she has some incredible facts about the camera and excited to share those facts.
Imagion the fire you could light with that!!
Yea forget ants, now we can do people.
Well if this doesn't get me on any watch lists nothing will!
Fun fact: The US government used the radiation from nuclear tests to light their cigarettes several miles away. I could totally see them using this telescope for something similar.
@@vizionthing Nah
You're okay
Doing a lens so large is not a trivial thing
Unless you are working with a lot of people and everybody knows exactly what they are doing
Yeah. Probably the light from a single match would be enough for that!
I actually worked at a telescope site where that was a major concern. The mirrors used could focus such a massive amount of light into such a small amount of space that if the doors behind which the mirrors were held were opened they could easily light an intern on fire.
"We're building one of the most advanced telescopes ever" "what are you using it for?" " oh, things you can't see" 🙃
Yes but in a way, isn't every telescope and microscope for "things you can't see"? :)
There's this photo that someone took of our dark side of space, and you can literally see thousands of galaxies that we would've never seen before! I'll look for it and share it here. The best thing to look at isn't the know, but the unknown

We're building one of the most advanced telescopes ever...
What for?
Oh, for things you can see.
That sounds useless, doesn't it?
Yeah for dark matter. It’s called dark because it doesn’t interact with light but we can see every minute effect dark matter does have on everything else.
Think of seeing leaves blow in the wind. We can’t see the wind, but we know it’s there because we see the tree move :)
I love how Diana is so smart and knows a lot of stuff and yet she's so humble and down to earth ❤
I love how happy you get when you see or experience things. Don't ever lose that.
There's something weird about seeing a state-of-the-art digital camera worth $20 million being moved by a forklift that looks like it came off the assembly line around the time M*A*S*H was getting popular. Shouldn't they have a Jedi Knight or something on standby for tasks like that?
Classic..
And that single lifting point ,,,
I worked at DOE we had alot of old forklifts some from 60s..
We handle nuke stuff also.
All inspection and good.
It is much easier to lift an X Wing than a lens like this. This is covered in Lifting Stuff 203 of Jedi Training.
what are you trying to say? it sounds like you are just a massive bigot against forklifts..

Oh yes it's just cute how excited these small scientists are, squabbling about in their lab coats.
That is a very patronising comment. Of course they're passionate. What they are passionate about isn't some small deal either. They are passionate about more important things than most people.
@Lilith Not what I'm saying
In my first job out of school I worked on a 54" diameter lens with a focal length of 8.5 metres. This lens was a display centre piece for the newly opened Kodak Museum in Bradford and was at the time, I believe, the world's largest lens. I contacted the National Science and Media Museum and they confirmed they still have it though it is now in storage at the National Collections Centre and no longer on display.
Your physicing is contagious and we're all vicariously entertained. Thanks.
I love Dianna's child-like enthusiasm! It's infectious! Especially because it's genuine.
Because reality is that astronomer physicists are loons. They don't actually contribute anything to society and most of the "facts" and "findings" aren't true they are just imagined possibilities for purpose of funding and belief system.

@bigbadb10 ecectly my point.
Not for me. It looks like a lie.
I feel compelled to point out that cougars live in arid mountains and highland forests, so the odds of finding one in the jungle are not good. You might spot a panther though 😅
Joel Courcelles I think the Cougars she was referring to was the sort that wears Leopard skin print underwear......in the urban jungle...
I guess you could say that the things they will be looking for in the cosmos will be as rare as a cougar in the jungle...
They're widespread in South America even more than North America, so you will find plenty of cougars in the Amazon for instance. Though I think the name "puma" is more commonly used for the southern populations.
Joel Courcelles well, I usually see them at my local grocery store
Are you a fellow biologist like me?
I love how excited she is about LENSES, that's passion right there :)

Dang time flies. Ive got fond memories of Phil Pinto at UA talking about the early concept of the LSST, back when it was just a few sketches and drawings. They've come a long long way since those early days in Tucson. Bravo!
3:08 Does that mean that we could see lunar rovers?
I thought the same thing. But as far as I know is not possible to see them from Earth with any telescope
Focusing would be the biggest issue. Telescopes are made to focus on big and far things
There is something like theoretical limit for resolution based on wavelength, distance and aperture. I am pretty sure, that the thing with golf ball or the moon lander is not possible.
But I am not sure, may be somebody can tune in?
My back-of-the-napkin calculation of 320nm (UV wavelength) / 8.4m (primary diameter) x 360,000km (moon's perigee) yields a ballpark resolution of 14 meters. Online telescope resolution calculators yield slightly larger results (~24m).
Wikipedia lists the angular resolution as 0.7 arc seconds (median seeing limit) and 0.2 arc seconds (pixel size). The latter yields a resolution of about 350m at moon distance.
Seems way too broad to resolve a regulation golf ball.
I don't understand why people are saying it's not possible when the girl in the interview literally said they'd be able to see a golf ball at the same distance as the moon. If they will be able to see a golf ball at that distance and resolution, why wouldn't they be able to see *larger* objects *on* the moon?

@@Wistful77 If you have to add that, I'm sorry, but the level of advancement you are thinking of is not sufficient.
If magic existed, and it would follow rules, then science would just study it and it would cease to be "magic".
Magic, especially "Vancian" magic, is practically studied (well, discussed and ruled at length) in RPG of DnD and fantasy literature. So you could say it does follow rules.

Great topic Physics Girl 👍
“Crispiest”...I like it! Thanks for the exposé!
well this is the most useful video ive seen in weeks .. good job n keep up the goods
3:08 So.. let me get this straight... This telescope will be able to take inch resolution images of the Moon? That sounds absurd. However, if that is true, it's amazing. Also, i can't wait for high res photos of the Apollo 11 landing site.
That's going to take a lot of photoshopping to add in the footprints and everything we supposedly left on the moon. It was staged, right? LOL
I mean, you could, but from the sound of it, you'd be buying some very very expensive replacement sensors, since the light of visible stars can overcome the focal field.
@@jamesburleson1916 As you can see in the video, they have the sensors in normal light, so there is no way starlight will damage the sensors. What she's probably talking about is that the sensors saturate at low light levels.
being able to see something at all, versus being able to finely resolve its details is a whole 'nother story.
I doubt it will ever be aimed at the moon. They're after bigger game. Or rather, smaller game.
I'm so excited. Saludos desde Chile!
Absolutely love this ... what an amazing experience !!
Survey taken. You get my highest vote (because I love the videos). The survey showed me there is a lot of other PBS RUclips content I would be interested in but I’m not aware of. I’ll have to check those out.
In 50 years, we will look back at this as such primitive technology, in the same way we look at the computers that ran the moon landing in 1969. That is mind boggling to me.
Fifty years? I remember the first time I saw a one-megapixel astronomical image. In fifty years, the technology that makes the LSST look primitive will look primitive.
Most deep space images you see are "digitally enhanced" and the real image doesn't give us any real information on what's going on out there. Most of what you hear about deep space knowledge is made up fairy tales designed to get more funding. When I say "fairy tales" what I mean is that there's large gaps in-between data that we are able to collect and what we can learn from it and you won't get more funding if you're honest answer is "it's too blurry to make out what kind of landscape it has and the data is to inconsistent to use any modern technology to answer any questions about what we are seeing". If you don't believe me you can find it in fine print on NASA official website on any planet picture they post that isn't blurry and also isn't Mars.
@@anotherguy1260 Lemme guess. Flat-earther?
@@cormyat07 so anyone who you disagree with must be a flat earther? No I actually do some digging into things I hear. NASA website admits to digitally enhancing pictures and raw photos are usually blurred. NASA has also released concept pictures on articles dubbed "new images" but if you read the fine print then you know it's not an actual picture.

"looks like a giant perfect water droplet"
I wonder if using actual water as lenses would be viable. Like using water as the refracting medium and using giant electromagnets and the diamagnetic properties of water to shape it like a lens.

this is so amazing, I'm chomping at the bit in anticipation of seeing such hi-resolution pictures from so far away it's hard to contemplate!!, will they be able to see as far back as the moment of the "big bang"? tune in next year's year and find out!

you can stay for Cougars but the Lenses are going to the Southern Hemisphere where they're called Pumas(actual species name).

Physics girl is a cougar. Yumummmmmm
1:29 wait... But weren't we about to use a group of telescopes soon in the future to see better and far away? Like they did with the black hole picture if I'm not mistaken?
I don't get it...
Is this telescope better than a group of the best telescopes working together?
More data does not meanbetter in every way. This telescope will produces lots of data, because it takes an image every few minutes with the largest CCD ever built (about 3000 megapixels). This is very usefull for its intended purpose i.e. detecting changes in in the entire visible sky by imaging all of it every 3 days. However most other telescopes perform much more specialized tasks to which the LSST would be entirely useless. USing your example of the Black hole event horizon picture: The minimum resolvable angle (i.e. how small is the smallest thing you can see) of this telescope is not actually particularly impressive compared to other single telescopes or as you mentioned multiple of (in the examples case Radio) telescopes working together.
Side note: this telescope also does not perform spectroscopic work beyond a few color filters. Most of modern astro physics is based on Spectoscopy rather than imaging.
None of which is to say that this will not be an impressive and usefull instrument, well outdoing anything in its *class*.
Projects like that collect a lot of data about a very, very tiny area. This is collecting data on the entire visible sky. It's like staring at one thing under a microscope versus going up on a mountain and seeing all the way to the horizon. But also the precise definition she's using to quantify an amount of data is kind of ambiguous.
And the EHT was a collection of radio telescopes, this is optical.
Fascinating! wow, that multi-part sensor and that "filter switcher", so much great stuff to digest :-)
Outstanding !!!! as this series ALWAYS is.
