Personally I'm extremely psyched for what comes out of it. As optical drive manufacture is winding down, there are some excellent manufacturing facilities out there that could easily be repurposed to making microscopes like these, as well as micro-scale 3D printers. If we can catch the wind there, we'll have these capabilities available for the tiniest amounts of money, available to every school and every school child. Who's going to make the kickstarter happen?
You're getting down voted, I think because people think you're hating on the Raspberry Pi, but I believe you might be talking about the current scarcity of it.
> with resolutions higher than can typically be obtained with visible light microscopes
But DVD lasers use visible light!
The constraint on the resolution of an optical microscope is the wavelength of light, right? A scanning electron microscope has higher resolution because it doesn't suffer that constraint.
The article doesn't explain this improved resolution. In fact at no point does the article definitively say that this type of microscope can resolve things that no optical microscope can resolve.
Yes, I used the word "definitively" on purpose. I'm saying the article's claims for superior resolution use weasel words. "Typically" is such a weasel word.
re: "Wasn't this posted 3 days ago?" as someone just asked in a now deleted comment.
OP's profile shows submitted 3 days ago. Front page shows submitted 9 hours ago. Both link back to the same story.
HN does sometimes boost stories that didn't get attention they felt they deserved. It looks like that may have happened here because the story ID is consistent with having been posted 3 days ago.
Edit: And if you mouse over "9 hours ago" it shows the date 2022-10-01.
Around 2.6 times: "This allows a reduction of the pit size from 400 nm for DVD to 150 nm for Blu-ray Disc, and of the track pitch from 740 nm to 320 nm".
Kids have too much Art and not enough Science as it is, thats why we developed a STEM focus.
STEM is science, A is everything else. "The arts and sciences", they are separate for a reason, and the reason is that Art won't feed you and Technology will.
STEAM is a bastardization, a dilution of STEM and of the education of children.
There is room for Art, but if you lump it in with engineering, suddenly the focus is all art and we're right back where we started before we had STEM as an acronym.
Reminds me of the Copenhagen Design Museum. Full of completely useless modern-art-esque "takes" on various items (one specific highly practical item notwithstanding: a specific chair design).
"Design" means achieving an optimum in a highly multivariate requirements space: functionalities, ease of use, aesthetics[1], cost, material use, robustness, longevity of the design[2], scalability, cost to the user, cost to manufacture or provide, ease of marketing[3], etc etc. Which basically none of the exhibits actually showed.
If you focus only on the form, it's "just" art. A worthy endeavour, certainly, but it's not the same thing.
[1]: extremely variable among people so an optimum that many people agree on in this axis is very hard to reach. "Great designers" often are famous specifically for excelling here without major impairment of other requirements.
[2] can you still make it next year, next decade? Will people still want it even if you can?
[3] it can be easier to market a lesser product, say, that's cheaper, even if it's disproportionately worse for that lower price
Yeah, it’s pretty dumb. Science is fundamentally objective, art is fundamentally subjective. That’s a solid distinction.
I think the idea of studying art is wrong in and of itself. It’s interesting and possibly useful from a technical/historical standpoint, but the idea that you can go to school to learn how to be a good artist is silly, in my opinion.
That's an odd take. Studying art, like studying any subject, is a great way to be exposed to new ideas and fresh perspectives, which in turn informs and inspires one's own creativity and understanding.
Sure, but I think it’s like being a sports commentator vs a competitor, or a film critic vs a director. Tarantino, Van Gough, Jimi Hendrix (and the like) all achieved greatness without any institutional backing or education, as far as I’m aware.
I was going to just write a vague comment that many of the world's best painters, musicians and film makers have studied before they became great, and cherry picking a few who haven't doesn't prove otherwise. But actually I remembered Van Gogh already is the opposite example than you think.
Van Gogh: "He traveled to Brussels later in the year, to follow Theo's recommendation that he study with the Dutch artist Willem Roelofs, who persuaded him – in spite of his dislike of formal schools of art – to attend the Académie Royale des Beaux-Arts. He registered at the Académie in November 1880, where he studied anatomy and the standard rules of modelling and perspective."
edit 2: If interested in other examples, check out alumni lists of places such as London's Royal Academy of Arts (where for example, J. M. W. Turner, one of the most famous British painters of the 19th century, enrolled as a student at the age of 14; and where actors such as Alan Rickman, Tom Hiddleston, and Anthony Hopkins - among many others - studied). https://en.wikipedia.org/wiki/Category:Royal_Academicians
And the RA is far from the only place with a history of teaching some fantastic artists. You'll find a few, or many, famously successful people who've studied at pretty much any of the best places to study arts in the US (https://www.artsy.net/article/artsy-editorial-15-top-art-sch...), or at the École des Beaux-Arts, Paris (students including impressionist painter Edgar Degas, or American architect John Russell Pope who designed the National Archives and Records Administration building as well as the Jefferson Memorial, among others), etc etc.
(You can stop reading this comment here probably, unless you're interested enough to go on - it's quite long after two edited additions...)
Absolutely there are plenty of people, both in creative areas and in business and science etc, who've got to the top of their game without formal education, thanks to talent and self-driven learning. It wouldn't be hard to pick a handful of cities from around the world and name from each just as many examples as I've given of extremely talented, and famous for it, artists who didn't have formal education.
But there's plenty who did have either personal mentors/tutors, or degrees in their field, and while nobody would suggest that their education was 100% (or close) of what made them a great artist, plenty of them do attribute it (either institutionally or just their mentor) partly to thank - just as some consider it wasted time with hindsight.
edit: Anecdotally, in my youth I was a professional singer - nothing fancy or famous but salaried for a few years of recordings and tours. Not only did I keep working with a singing teacher who helped me on any issues I had (early on most issues would be ones pointed out to me, in my last year or two nearly all sessions were focussed on whatever I wanted to work on), but pretty much everyone I sang with who was either early in their career, or who sometimes / often sang solos rather than just in a choir chorus, had lessons from some sort of mentor (or more than one). As far as I'm aware, even those I sang with more than a decade ago who didn't move on and are still singing, in some cases as somewhat well known soloists in their areas, still have a coach/mentor to help keep their voices in good shape and even to keep getting better and better.
I'm also one of many, many people who, as kids, were lucky enough to have the chance to not only have a musical instrument but to have weekly lessons for it. I would guess that if you look at the most successful pop/rock stars, maybe it's less common to have had those sorts of lessons growing up, if you look at classical music greats it would be the opposite way around, Jazz somewhere in the middle... etc. (I could be way off). Which isn't to say there aren't pop/rock artists who had a good musical education (a couple of people who shared teachers with me have had chart hits here in the UK), nor that there aren't classical music performers who taught themselves everything they know (/ learning by watching greats who inspired them).
There's really no right or wrong way to become a great artist.
I think that can limit creativity though. Look at Albert Einstein. I don’t think he had much of a formal education, certainly he was not involved with any institution when he wrote his groundbreaking paper.
Sometimes, being involved in big, political institutions can have the result of stamping out original/independent thinking in favor of established dogma. To be clear, I’m not arguing against the act of learning in itself - Hendrix and others learned on the job, so to speak, and listened extremely widely. I guess I’m speaking more against formal education/credentialism, which of course has its place, mostly in the hard sciences where it is important to have an objectively good understanding of the dogma.
But again, you've picked a single wonderful scientist as if that proves all great thinkers followed his path. Does Einstein not having a formal education somehow mean that all great thinkers just have had the same life path as him? It's just nonsensical, sorry.
Marie Curie was a student at the University of Paris. Isaac Newton at Cambridge University. Charles Darwin studied at the University of Edinburgh. Nikola Tesla couldn't go to university but he completed 4 years of high school in 3 years and "later wrote that he became interested in demonstrations of electricity by his physics professor". Galileo Galilei studied at the University of Pisa.
Or stepping back away from science again, David Bowie. From Wikipedia again to save writing: "Bowie studied art, music, and design, including layout and typesetting. After Burns introduced him to modern jazz, his enthusiasm for players like Charles Mingus and John Coltrane led his mother to give him a Grafton saxophone in 1961. He was soon receiving lessons from baritone saxophonist Ronnie Ross."
Again, since you seem to miss my points in my last comment: I'm not saying education is required for greatness, nor better for all people (Einstein certainly tried formal education and hated it). But to say it prevents creativity is just wrong, except for bad education.
Maybe you're basing things on your experience of school / child education which wasn't good enough for you?
I don’t think there’s a right or wrong here. I think there are strong arguments on both sides. What I would say is, I think Hendrix would’ve been booted out of a higher education system due to not conforming to the established principles of music theory, or some such thing.
You almost certainly can't teach whatever it is that makes a great artist great. Just like you can't really teach the mindset and thought processes that make a great engineer great. But you can teach techniques, and you can encourage practice of the craft, and teaching exposes people to ideas that they might not be aware of otherwise.
Good teaching is very rarely "this is a fact you must memorise", but putting the right environment in place for someone to do something themselves. If someone goes to art school, has a class on pottery, learns how to use the wheel and the kiln, and then becomes a renowned potter, did they learn that at school? Probably not the part where they became renowned - but the school did provide them with the tools to get there.
I think it's only wrong in the sense that lower levels of education are biased towards a kind of rote memorisation of bashing everyone into performing the same basic task in the same way to get the same results which look good on the test. That is certainly something which is more likely to have a negative effect on an artist's potential than anything else (but the same is true of any other subject IMO). Actual careful study which involves acturally engaging with the subject will generally enhance anyone's capability in the subject, even if in art usually you succeed by breaking 'the rules' in some way or another.
Just as often, arts gets the short shift. Art in a "STEAM" program is likely to be more like design (Photoshop, logo design, etc).
I think it's a bunch of enthusiastic education administrators who don't spend much time in schools, but think they can make science fun and art more business friendly if they find a bit of synergy.
Really? I would say that it is art which is suffering in education at the moment. And much as many people leave high school with a lack of understanding of basic maths and science they also leave with a lack of capability to engage with media in anything but the surface level. Fundamentally everything in STEAM is a creative endeavour of some form or another and I think they are a lot more alike in the skills and techniques that let you succeed than people like to pretend.
Art and science have their similarities. For instance, art is the exploration of the space of possible emotional truths, while science is the exploration of the space of possible statistical truths. Design and engineering are opposed to both art and science, in that the latter are open-ended explorations that by construction do not pre-suppose an end goal. Design is teleological, and engineering is just a means to bring designs to fruition. So examining the acronym closer we notice that even design is excluded from STEM which seems like a huge oversight -- you don't want engineers who are not practiced in designing functional, reliable systems...
Art is a very important part of the development of people as positive forces in society and civilization, and so presumably, if we assume good faith to explore this question, we could posit that people are reacting to the exclusion or at least de-emphasis of art education in conjunction with the typical STEM curriculum. The intention and goal is I believe best summarized in the famous quote from Jurassic Park: "your scientists were so preoccupied with whether or not they could, that they didn't stop to think if they should".
The "and" in "arts and sciences" is not a logical operator, it already suggests a union of the sets. The "arts" portion allows one to communicate clearly, understand motives, etc.
I've never seen the STEAM acronym, and agree that art as colloquially used certainly has no place in the STEM acronym for that acronym's intended usage. That said, how do you interpret the phrase "state of the art"? What does "art" mean in that context?
Agreed. "Arts and Sciences" covers it. What part of technology and mathematics are not already part of science? (Signed, Department of Redundancy Dept.)
