harry potter - How can electricity not work at Hogwarts?


In the Goblet of Fire, Hermione says:



All those substitutes for magic Muggles use – electricity, and computers and radar, and all those things – they all go haywire around Hogwarts, there’s too much magic in the air.'


Goblet of Fire - pages 475-476 - Bloomsbury - chapter 28, The Madness of Mr Crouch



But it is impossible for electricity not to work. If electricity didn't work then:




Well, the universe literally would not exist as we know it, because electricity is streams of electrons, and without electrons, compounds (and thus most matter) wouldn't exist. If electricity (electromagnetism) did not exist the universe would not exist, since EM forces are an integral component of the (commonly accepted) standard model.

Besides is it just me or our brains work on basis of sending electrical impulses through neurons?


So how can electricity - and I don't mean electronics, but basic electricity - not work?



Answer



As to a possible explanation it might be a localized limitation of EM field functions E.g. similar to the "damping fields" which have been used in Star Trek. This would include ST:DS9: Paradise in which a duonetic field artificially suppressed EM functions.


As a further example, of suppression of high-energy-density electrical items vs. lower density items such as bio-electricity. you might check out S.M. Stirling's Dies the Fire series. In it, not only electricity but gunpowder, steam engines, etc. do not work. The key difference being the level and density of the electrical/heat energy being artificially produced.



In particular given the "magical" overtones which later come to the fore in Stirling's universe, as the likely cause of the "Change" it would be similar to the Hogwart's damping.




Neither of these explanations would necessarily be in in-universe explanation for the Potterverse. But, such a phenomenon is certainly common enough in regular SF situations, not too mention more Fantasy based stories.

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.

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 !...

Is there good canon evidence for the "Nightmare Matrix"?

On the Matrix wiki, there's an article about the Nightmare Matrix which says: The Nightmare Matrix was the second prototype Matrix, designed by The Architect after the massive failure of the Paradise Matrix in the hope that human minds would more readily accept an imperfect world with suffering. Unlike the first version, this Matrix instituted a basic cause-and-effect programming and forcibly made those connected to it accept the program. Vamp Prime, a possible remnant of the Nightmare Matrix. It also featured programs that resembled mythical evil creatures in various human mythologies such as vampires, werewolves, zombies, aliens, etc. It also failed, but many of the programs who were designed for it survived deletion in exile. The Merovingian and his wife, Persephone may have had their roots in this version of the Matrix. Upon its failure, the Merovingian started a smuggling ring of programs and information to provide a haven for exiles that would last for 6 cycles in the final ...

story identification - Anime with a boy hiring a creature from a stone, meets a man named Dante and starts a journey to collect crystals

I am from India, this anime or animated series (I can't remember this was made by the Japan or other countries) was aired between 2009 and 2012 probably in Jetix/Disney XD (but I'm not sure). This anime starts with a boy (the main character, I forgot his name) who find a stone (or crystal like thing) in his dad's property, his dad was missing that time. Some day he accidentally hire a creature/monster from that stone. Other day some creature attack him and he was saved by his creature and the story begins. In his journey to solve the mystery he meets a middle aged man 'Dante' (probably that was the name; this is the only character name I can remember). He had also some stone. After that they meet with one girl and a women (one of the girls is same age with the main boy character and probably will become his partner as the story goes on). Another women probably Dante's partner. Four of them started their journey to collect all the stone/crystal. They are collecti...
