star trek - Do Starfleet communicators require a server?


Do we ever find out, anywhere in Star Trek, whether standard-issue Starfleet communicators (e.g. TOS-era handheld communicators or TNG-era commbadges) require a server to communicate (like a cell phone), or whether they are capable of direct peer-to-peer signaling, without the intervention of any server/trunked system (e.g. based on a starship, satellite, land base station, etc.)?


For example, if two Starfleet officers were stranded an arbirary distance from Federation resources, without anything except the clothes on their backs and their commbadges, could they communicate with each other over a reasonable distance, or would they get "no service" error messages or similar?


If a Starfleet communicator can be reconfigured on the fly to serve as a server/hub for communicator networking, that counts as an answer (e.g. "Our ship just blew up and we are alone, so let's reset our communicators to not depend on our lost ship. Lt. Jones, tap the code onto your communicator to set it to Server Mode, and everyone else sync to his").



Answer



No


If we look at the few times in various series when everyone was far removed from compatible technology, we find that they can work just fine without. Off the top of my head, in TNG episode Time's Arrow (pt 2), while in the hospital ward Dr. Crusher uses her communicator to signal the others- it's not like there was a Federation server kicking around San Francisco in the 1800's.

There is also ST:IV, where the Enterprise crew uses their communicators while on Earth in the 80's. Yes, while it's true that the Klingon Bird of Prey they had could have acted as a server, given the unfamiliarity of the ship, they probably didn't use it in that capacity.


In the instances when they couldn't use communicators, it's usually due to some other external factor- dampening fields, phase shifting, etc. Probably along the lines if the ship can't scan it or inside it, then communicators are also worthless.

futurama - How much time is lost in 'Time Keeps on Slippin''

In time Keeps on Slippin' , Farnsworth creates a basketball team which he matures by abusing Chronitons. This leads to time skipping forward by random, but ever increasing amounts. How much time was skipped in this way? Answer Unfortunately, I don't think a good estimate can be made for this, for two reasons: Many of the time skips move forward by an indeterminate amount of time. At one point, the Professor mentions localized regions of space skipping forward much more than others. We then see two young boys on the street below complaining about having to pay social security, only to suddenly become senior citizens and start complaining about wanting their money. Thus, each individual could have experienced a different amount of time skippage.

What is Tolkien trying to say in this letter?

In a draft of a letter, later recorded as #246, Tolkien makes a strange statement. I am interested in the first few sentences of the letter, but I will include the remainder for the sake of context. In the 'Mirror of Galadriel', 1381, it appears that Galadriel conceived of herself as capable of wielding the Ring and supplanting the Dark Lord. If so, so also were the other guardians of the Three, especially Elrond . But this is another matter. It was part of the essential deceit of the Ring to fill minds with imaginations of supreme power . But this the Great had well considered and had rejected, as is seen in Elrond's words at the Council. Galadriel's rejection of the temptation was founded upon previous thought and resolve. In any case Elrond or Galadriel would have proceeded in the policy now adopted by Sauron: they would have built up an empire with great and absolutely subservient generals and armies and engines of war, until they could challenge Sauron and destroy ...

harry potter - What is the difference between Diffindo and Sectumsempra?

In the Harry Potter books, Diffindo is called the 'Severing Charm' and it’s most commonly used to cut ropes and the like. However, in the last book Hermione uses it on Ron but misses, creating a 'slash in his jeans' and his knee gets cut, causing him to 'roar in pain'. We've only seen Sectumsempra used once on screen when Harry directly uses it on Malfoy in the sixth book, but there it's mentioned that he is 'waving his wand wildly'. Wouldn't Diffindo, if used in such a fashion also cause a similar effect? Similarly, if it was able to cut Ron, it would also be able to, say, chop off an ear (George's)? In that case, how are these two spells different, except for Sectumsempra seemingly used exclusively to hurt humans? Answer While Diffindo and Sectumsempra both can be countered by other spells, Diffindo is far more easily countered. Reparo, a relatively common spell, can completely reverse its effect when used once. “He pulled the old cop...

harry potter - How could Expelliarmus beat Avada Kedavra?

I want to be very careful about how I ask this question – I am not asking How did Voldemort die? [CLOSED] Below the text is the relevant passages from Harry Potter and the Deathly Hallows if anyone wants to review them (I'm sorry for the amount of text). How did Expelliarmus beat Avada Kedavra and kill Voldemort? I feel the reason Harry's Expelliarmus overpowered Voldemort's Avada Kedavra curse has to do with who was master of the Elder Wand and how the Elder Wand works. I've always had trouble understanding fully how the Elder Wand works, though. How much did the fact that Voldemort never truly won or mastered the Elder Wand factor into how Expelliarmus reacted to Avada Kedavra and caused Avada Kedavra to rebound and kill Voldemort? An answer based in book canon would be especially welcome, but any canon source really is fine. Harry heard the high voice shriek as he, too, yelled his best hope to the heavens, pointing Draco’s wand: ‘ Avada Kedavra !’ ‘ Expelliarmus !...
