powers - How does Spider-Man climb walls?


How does Spider-Man's "sticky" powers work? If his ability to climb walls works in the same way as spiders and most other insects (e.g. due to Van der Waal's force of attraction) then his hand should have microhairs or thorn-like structures as shown in 2002 Spider-Man movie, which means he should not be able to climb walls while wearing his gloves since those structures can't pierce through gloves.


If the thorny structures are sharp enough to pierce through his clothes then how does he use his hands (like giving handshake to other people) without hurting them?



Answer



The only possible explanation is that spider man has some kind of re-tractable micro structures which allows him to climb wall and is sharp enough to pierce through his clothing. This offers him control while climbing wall and he can retract this structures into his skin so that he does not harm others with them (while giving handshake ). Moreover there is a possibility his skin may secrete some kind of fluid to increase this stickyness (whose secretion can be controlled by him).



A panel of biologists and physicists on the History Channel’s Spider-Man Tech suggested the barbed-hair on his fingertips (from the movie) could have the same effect as the miniature scopulae hairs on the ends of a spider’s feet. Spiders are able to climb up seemingly impossible surfaces like glass because the scopulae interact with the glass’s atoms causing a form of atomic static cling via the Van der Waals force



there is a possibility that this Van der Waals force may pass through his clothes thus not requiring the micro thorn structures to pass through the gloves.




Van der Waals force is nothing is the sum of the attractive or repulsive forces between molecules (or between parts of the same molecule) other than those due to covalent bonds, the hydrogen bonds, or the electrostatic interaction of ions with one another or with neutral molecules or charged molecules as given in wikipedia



which indicates the presence of dipole.So what electro essentially does that is change the charge (he essentially neutralizes the dipole induced by spidermans fingers ) using his powers.

harry potter - Did Dolores Umbridge Have Any Association with Voldemort (or Death Eaters) before His Return?

I noticed that Dolores Umbridge was born during the first Wizarding War, so it's very likely she wasn't a Death Eater then (but she is pretty evil -- who knows?). After that Voldemort was not around in a way that could affect many people, and most wouldn't know he was planning to rise again. During that time, and up through Voldemort's return (in Goblet of Fire ), did Umbridge have any connection with the Death Eaters or with Voldemort? Was she doing what she did on her own, or was it because of an association with Voldemort or his allies? Answer Dolores Umbridge was definitely not a good person. However, as Sirius points out, "the world isn't split into good people and Death Eaters". Remember that he also says that he doesn't believe Umbridge to be a Death Eater, but that she's evil enough (or something like that). I think there are two strong reasons to believe that: Umbridge was proud to do everything according to the law, except when she trie...

What is the etymology of Doctor Who?

I recently decided to watch Doctor Who, and started viewing the 2005 version. I have the first two episodes from the first season, and I can't help but wonder what is the etymology of the name "Doctor Who"? And why does the protagonist call himself "the Doctor" (or is it "the doctor")? Answer In the very first episode of Doctor Who (way back in 1963), the Doctor has a granddaughter going by the name "Susan Foreman", and the junkyard where the TARDIS is has the sign "I.M. Foreman". Barbara, who becomes one of the Doctor's companions, calls him "Doctor Foreman" (probably assuming that is his name given his relationship to Susan), and Ian (another early companion) does the same in the second episode, to which the Doctor says: Eh? Doctor who? What's he talking about? "Foreman" is most likely selected as a convenient surname for Susan to use because it happened to be on display near where the TARDIS landed....

story identification - Animation: floating island, flying pests

At least 20 years ago I watched a short animated film which stuck in my mind. The whole thing was wordless, possibly European, and I'm pretty sure I didn't imagine it... It featured a flying island which was inhabited by some creatures who (in my memory) reminded me of the Moomins. The island was frequently bothered by large winged animals who swooped around, although I don't think they did any actual damage. At the end one of the moomin creatures suddenly gets a weird feeling, feels forced to climb to the top of the island and then plunges down a shaft right through the centre - only to emerge at the bottom as one of the flyers. Answer Skywhales from 1983. The story begins with a man warning the tribe of approaching skywhales. The drummers then warn everybody of the hunt as everyone get prepared to set "sail". Except one man is found in his home sleeping as the noise wake him up. He then gets ready and is about to take his weapon as he hesitates then decides ...
