Lately I've been wondering if there is any practicality in using CCDs transmitting telescopic images to a PC/Laptop and Monitor especially at longer exposure times since the more dim and distant objects appear to us with relatively small displacement that would make for fuzzy imaging. Has...

I don't know if this is the ideal sub-forum for this but I'd like to know more about this very recent activity I first saw here >>>>>' It looks like this could be some actually testable, actual breakthrough advances in Physics and the evolution of our Universe. Any comments appreciated.

On a lesser note I binge watched the new season of The Expanse and while the cast and production are as compelling as ever, I found it mildly disappointing but that is probably due to the "tough act to follow" syndrome. Not every writing team or story can conclude a brilliant story as perfectly...

I'm rather impressed with a new (2019) gem from the UK which may be rather unfortunately titled Cosmos as there is bound to be some confusion and blurring over that title, but it is well worth seeking unless you don't enjoy the geekier films of the genre. It starts very slowly and takes a long...

Incidentally for those of us who enjoy positive message Sci Fi suitable for whole family viewing Disney's Tomorrowland is a decent experience. It poses a great riddle for kids (and maybe some adults) to ponder - Some of the Science is typically Disney child-like but it displays a trust in...

I just realized there's a gap in my reading here. I did finally get to see a few seasons of "Expanse" and it's really quite good. I also recently viewed High Life and I concur. It's good and the blend mention is accurate and who wouldn't love a blend of Solaris and Silent Running?

I recently watched what may come to be an important milestone in Sci Fi. Don't get excited yet since it is by no means a "pulse-pounder". It is the 2017 film, The Beyond . I liked this movie rather a lot while at the same time understanding it's low rating and probably low appeal as far as...

Whew! Gentlemen, thank you... that helped. For a minute there I was beginning to imagine giant caterpillars smoking hookas might be real ;)

Please forgive my denseness in this matter but my only excuse is that I am literally a half century out of College and I haven't used much beyond rudimentary calculus in any job I've worked. From my learning integers are perfect abstractions because they are constructed and defined that way. I...

He didn't say the opposite. Both are technically consistent. If I may speak on mfb's behalf I think he was merely noting that pressure and volume in a closed system are usually inversely related. You can experience this with a simple garden hose and an adjustable nozzle.

A net search today resulted in a more pointed, more thorough and scientific perspective. https://www.medicalnewstoday.com/articles/321566.php If you have interest don't miss the articles listed by links to the right, especially the CalTech item.

Greetings Since genome sequencing is apparently having a major impact on medical science, just to name one field, I am interested in hearing/reading more about this recent event regarding autism. It seems to me this could have far-reaching implications and possibly major impact on how we view...

BTW while this might be "bringing coals to Newcastle" I figured I'd better be perfectly clear that my reference and kudos above for The Arrival does not refer to the Charlie sheen movie of a few years earlier. I was referring to this one https://www.imdb.com/title/tt2543164/. The Charlie Sheen...

It is interesting that you seek to achieve 5KW since that brings back memories of a kit i bought about 40 years ago from a company listed in The Whole Earth Catalog. The kit was for a set of instructions for adapting a Dodge Dart w/ Air Conditioning alternator to produce 5KW-6KW by crafting a...

Yup... not Pop Sci. Here's a recent reference from Phys.org https://phys.org/news/2018-05-quantum-effects-photosynthesis.html

I had been saving up to buy a decent telescope for my adult Son when someone bought him a cheapo (I think under $150 USD) as a gift. I don't think it's actually bad but it doesn't solve my two-pronged plan to get my prodigious grand-daughter interested as well as the height at which the tripod...

My vote would go to the confirmation by Curiosity on Mars that the degree and type of radiation levels do not prohibit human exploration even with today's technologies. I think this impacts several important areas , historic and future, and is a major breakthrough since either unknown or higher...

Hello again phinds. You have my apology for being at all obtuse but it was only yesterday from digging a bit deeper into the Fermi project that I got confirmation they expect to get data directly pertaining to dark matter. When I posed the first question it had just seemed to me it might and...

Well it was a long shot since so little is known about Dark Matter interactions (especially by me) but I wondered if the new refinement techniques being applied to the Fermi Telescope's All Sky map revealing deep level views of structures previously unseen or even unimagined are already having...

I'm curious, phinds. Are you wondering if recent discoveries by Fermi All Sky imaging revealing Xray and Gamma Ray bubbles apparently caused by near relativistic electrons whose source is unknown bears on this, favoring one over the other?

Greetings. I read about the possible role of sulfur here at https://arstechnica.com/science/2018/06/finally-scientists-have-found-intriguing-organic-molecules-on-mars/ Here is a short quote Since then I've also read that the presence of sulfur may also help determine if these molecules were...

I was trained in Engineering and I'm weak in Organic Chemistry so I don't yet understand why sulfur may play a role in the preservation of these samples so near the surface. Can anyone here shed some light on this process?

I very much like this new thread and sincerely hope it flourishes for here we expose each other to "where the rubber meets the road" where we all got our love of Science in the first place. I was struck by the fascinating "answer" Feynman gave when asked "Why?" in the "Magnets" clip and how he...

Grrrrrr For some reason the edit button is failing repeatedly so rather than continuing to beat my head against a brick wall I'll just amend it here. The last sentence in the 3rd paragraph should have been clearer and more specific, reading "... so little change in TNG compared by before and...

Hello ryan_m_b, nice to "meet" you. Of course since i wasn't there and any personal accounts of experiences are colored by personal POV all I can resort to is "proof is in the pudding". Let's start with the easy one, sexualizing characters. Some level of that is almost always going to exist on...

I may have already answered the base question but just in case I didn't and since I feel very strongly about this although I started out with Original Star Trek (yeah... I'm old :) ) and enjoyed it's depth of layers that circumvented commercial compromises to a degree, hands down the fullest and...

While it is a wonder as well as to our species distinct advantage that Professor Hawking managed to live and be so profoundly productive for so long, and though his death always seemed more imminent than most for that reason, I am stricken by this sad news. I will be sad this entire day and some...

While that may be regrettably so, anyone who knows anything about PC security considers such practice for anyone concerned about Meltdown and Spectre to be akin to worrying about their lack of motion sensor triggered lighting while leaving on vacation with their front and back doors not only...

Yes that can be defined as a local attack since it requires one either activating the code or allowing that code to activate by default. The former is usually in the form of some clickbait but also includes opening pages, including email, of unknown sources. It is, after all, possible to embed...

While these newly found hardware level vulnerabilities are indeed serious it is also important to keep perspective on how they affect us or can affect us, first as individuals and secondly "in the wild" using the services of others. One fact remains that has always been true and that is the...

It is important to note that these vulnerabilities occur at HARDWARE level and do not require privilege escalation. It is not yet clear if even CPU microcode updates will be sufficient to completely defend against such attacks as, unlike software dependent attacks, no logs are triggered. AMD...

It seems Bureaucratic mentality is common in SciFi so we simply must mention the hilarious Hitchiker's Guide Vogons which is a terrific book and a rather decent film. I nearly needed my towel to dry the tears from laughing so hard.

Both thumbs up for "The Arrival" ! It's not exactly monster fare. It isn't Space Opera. It doesn't have scantily clad Moon Maidens BUT it is up there on a par with 2001 and Contact. In fact in some ways it is even better because it is so believable with just a few teensy weensy A"suspend...

<Big Grin> I came for the Sci Fi and stayed for the Babes... I mean the quality of acting ;P Oh wait. That was Under the Dome... nah both had ummmm good acting...OK and babes.

Perhaps an ignorant question, but how can we conclude that remembering is always at a greater state of entropy than the thing remembered was at the time? It is my understanding that while the entropy of the overall Universe is increasing we also know that, given locality, entropy can decrease...

Have you guys seen the trailers yet for Alien: Covenant? While I'm not overly fond of the Horror genre I have to admit that the first time I saw the alien pilot corpse in the original Alien I couldn't help but to want to know more... much more about his/her/its backstory. The newest episode...

I grew up on TOS and like Dr Who defended it against morons who didn't get that it took place on many levels. "You want Monstahs? We got Monstahs!" but if you pay attention the real plot is underneath, subversive and ...well... fascinating. That said the fact remains that as a network...

Global Climate Change deniers are fond of stating that when an ice cube melts in your glass there is no increase in level. I suppose they choose to ignore that the ice in glaciers of all kinds are either on land or attached to land. So I counter with - Take a full glass of water and drop an...

It's probably been mentioned but since it has become an ongoing series and a good one at that, it's worth risking a re-mention - Ender's Game - The film is decent which translates into nearly awesome when referring to the average Sci Fi film and the book is very good being both entertaining...

Certainly one experiment/observation does not a proof make but it is my understanding that the ESA Integral data from 2004 re; GRB 041219A is at least hard evidence that the Universe is not grainy down to 10^ -48 meters, substantially lower than the Planck Scale by orders of magnitude. It seems...

Thanks for that, rbelli1, if you follow the youtube links a few of the included clips from raytheon show the modules manufacturing process. It's quite fascinating to me, and, yes, production was really difficult. Indeed, it was only a first small step and rendered fairly quickly obsolete with...

Greetings all In the mid 1960s Raytheon developed the first microcomputer chip ICs and Rope Memory that would get us to the moon. Apparently within a mere 10 years these historic small steps that were more than a decade ahead of their time and of considerable historic value were auctioned off...

Or get a Singapore Sling-box? ;)

Thanks for that link Noisy but it says that The Expanse is available in Singapore.. that's it.

Bandersnatch, apparently I need to borrow your Vorpal Sword to find "The Expanse" on Netflix. :) I searched for "expanse" and all I get is "related" videos. It's on Amazon but not available on Prime. Any hints?

Regarding the comparison of Space Travel to Early Human Migration, IMHO this is entirely an apples to oranges (flawed) attempt. Ground travel can be viewed in small steps in which each step still has the means for survival close at hand. Water travel is a bit more comparable but at least...

That whale clearly forgot to bring a towel. ;)

Last night I watched an unusually good film (German made with English soundtrack) recently added on Amazon Prime, called The Rosetta Mission.. It does cover some nicely technical issues not commonly seen on film and covers more than just Rosetta. For example it goes into some detail on just...

ping ddd123 - I'm still looking but as you may know Mr. Smolin is a prolific writer and speaker. The problem in finding just that one is like finding a needle in a stack of needles since it was/is not labeled "ESA", "Integral" or with any such cues. He is painfully aware of the deserved...
