I could imagine that 3D printing could be scaled up in speeds of "write-unwrite" to 60 hz, which would offer a 3D video . Materials are made with a compression algorithm to simplify background info, concentrating on active elements which would require the most data. This could allow a "circular fishtank" arcitechure to upcoming television...

I lost my mother at the relatively tender age of 67 a few years ago. I lost my 24 year old son 3 months ago unexpectedly. I am struggling to cope with the grief and my moods are rollercoasting like a teenager. At least my mother had a reasonably good run but aged 24? How have others coped with grief? Can things get any worse?

I apologies.. Arete and CharonY as well as the moderating staff and I also like to apologies to swansont from the physics forum. I'm from a confrontational culture and it's finals week so I've been a little stressed out in general. With that said, I respect you guys' expertise, knowledge, experience, and do realize my own inexperience and ignorance. Though I feel as though I have good things to say and I get all worked up when I think that one of you guys' has misinterpreted or misunderstood my point.

A related question must be answered to know the answer in the Topic of this post. What are the limits to energy storage in super capacitors, especially energy density and energy/mass. If the energy density and energy/mass are similar or better than liquid fuels, then I believe it is possible; otherwise, not. The electric charge could power a laser to heat air inside a jet engine, or some unspecified working fluid inside a rocket engine to create propulsion. The difference between jet and rocket is simply the rocket must carry the working fluid, instead of it being air. For example, a rocket might carry water which would be vaporized by a laser in the combustion chambe…

On every science board and physics-related video comments section, there is invariably a plethora of crackpots willing to endlessly spew their personal brand of buzzword-salad. They usually have virtually no math, physics, or even general science knowledge. They usually think they're smarter than everyone else. Attempting to correct them is like arguing with a wall. And they're always talking about physics. If there's crackpottery around, you can bet it's physics-related. But why is this? My guess would be that some of it is because of popsci books and documentaries that romanticize "the elusive quest for the theory of everything." That would explain the people who se…

I don't hold a degree of anything, but I'm interested to know at what age did you guys attain your first 4 year degree?

Finally, the last composition of the year, and my new years resolution to write more music has been fulfilled as this is my seventh song this year. This piece is an orchestration of a song my brother and I play on guitar that we named "Forged by Destiny". Although this rendition isn't exactly how we play it on guitar, I'm sure you'll enjoy the song nonetheless!

What is it that creates the thrill? I first saw Star Wars in 1977 as a young child with my mum and a few friends and whilst I really enjoyed it I wouldn't say it left that much of an impression on me - I prefered Superman, Smokey and the Bandit; even more - my elder brothers took me to see Close Encounters which terrified and fascinated me and had a life long impression on me. But I watch that trailer above and when that music from John Williams cuts in I feel a frisson of terror, excitement and anticipation - literally the hairs on the back of my neck stand up. It's silly and somehow atavistic - but magnificent and inspiring; are we all so easily manipulated? …

Hey, my parents want to know what I want for Christmas and I can't really think of anything. The only thing that came to mind is a book called "How to prove it: A Structured Approach" so do you guys have any ideas along those lines. I'm a high school senior and my interests are in Computers, Quantum mechanics, and Artificial intelligence. I was also thinking about asking for a mechanical keyboard so recommendations on that would be great.

Back in the 1990s and 2000s we had space operas like Star Trek, Battlestar Galactica, Firefly and Babylon 5. Why don't we see space opera shows on TV anymore? Did the network execs decide the genre was dead? Did people lose interest in space travel? Why is this genre dead on TV? If the genre does not appeal to anyone anymore what can be done to revitalize the genre? What can be done to make the genre more relatable? Do you think this genre should be revived? Either way I think we need more epic space battles and political intrigue on TV. It was long thought that fantasy was a genre once thought reserved for geeks but Game of Thrones has garnered a huge audience. Perhaps a…

quick question This paper was free, but they've moved it behind the pay gate. Why might they have done this? Can pedophiles be reached for primary prevention of child sexual abuse? First results of the Berlin Prevention Project Dunkelfeld (PPD) http://www.tandfonline.com/doi/pdf/10.1080/14789940903174188 I've linked to this paper to show that underage preferences are inversely related to adult-oriented preferences, with most of their convenience sample consisting of primary or exclusive-type pedophiles.

When ever my girlfriend or my friends ask me a scientific question, and I ACTUALLY explain the answer they tend to get annoyed and/or distracted. Sometimes they say I "talk just to hear myself talk" or that I "go on and on and on", but I'm just trying to illustrate the actual scientific reason behind the answer, and in return they get frustrated. I imagine I'm not the only person ever to have this problem? ~thoughts? ~EE

Hi, I'm a 4th year phd student and I've found that I have increasingly lost interest in working in science. Things are going relatively well for me, I have a great relationship with my advisor who is happy with me, I have published a couple of papers (just recently even got some coverage in the news) and I have been offered a postdoc position. My personal and family life is also satisfactory, no complaints there. My problem is that I have lost interest in doing scientific research, and so am not sure whether I should continue after my phD. I have seen other people talking about lack of motivation online, but usually they complain about frustration with their pr…

My happiness is the only reason for me finding good meaning about me as a person and finding good meaning in this life. Without that, there would be nothing good about me as a person or anything good in my life. I can just use my thoughts alone to perceive me and my life being good even without my pleasure. But these are nothing more than neutral (neither good or bad) thoughts and that would not make me or my life anything good at all regardless of how much I help others and do great things in my life. Therefore, since I no longer have any pleasure 24/7 due to my anhedonia (emotional numbness) in which there are never any brief moments of pleasure to any degree whatsoever…

When did you first realize how little you truly know? I was ~17, and decided to study special relativity because my high school physics class didn't go over it in any detail. I went through Taylor/Wheeler's "Spacetime Physics" pretty quickly, so I thought it would be pretty easy to learn GR. I bought a copy of Wald's book (not recommended for beginners), glanced through it a bit, and I suddenly realized that I actually knew close to nothing about physics. It's been ~4 years since then, and I'm definitely way more knowledgeable than I was, but I'm still blown away whenever I start thinking about how much is left to be learned. Anyone have any similar experiences wi…

My wife, a special-ed teacher has a student she thinks is dyslexic. She is not trained to teach dyslexics, and thinks this student should be tested for dyslexia. He is a challenge for her, so she asked me if there was some kind of glasses that could straighten out the letters for him. I said no, but a computer program might be made that reads pages with a camera, converts the picture into characters (OCR), and presents him with the words with the characters rearranged to help him. In other words, if he confuses d as b and b as d, then the program would change them to whatever he needs. Such a program would need a training session with each user to learn what each dy…
