Can Superman see through superconductors?

An important head needs to be answered by the editors of DC Comics ! Superman , one of their flagship characters , is famously ineffectual to see through lead — even though he can see microscopic substances , and he can see across immense distances .

What is it about lead that stymies Superman ’s super - visual sensation ? And would he have the same difficulty project through superconductors ? tops - science needs the answer to these head !

An easy ground why Superman ca n’t see through lead is because his imaginativeness is go - ray visual sense . tenner - ray notoriously fail to fathom lead . But as the years have passed , and as Superman ’s superintendent - vision has gotten more complicated , we ’ve memorise that it ’s not just tenner - ray that allowed him to see through objects . He ’s able to see thing that are too pocket-size , too soft , and too detailed for x - rays to ever be able to pick them out . Superman ’s tiptop - vision is , at this point , nearly all - sinewy . But it still ca n’t manage to get through lead , for some reason .

So what ’s so special about track ? After all , most of its physical properties are share by other subject matter . sure enough , it ’s malleable , pliable , and conduct electricity , but those traits are portion out by metals . Its sole unique strong-arm characteristic is that , unlike other metals , it has no virtual Thomson Effect , which is also known as Kelvin Heat . ( William Thomson became Lord Kelvin because of his uttermost cleverness in scientific discipline . )

The Thomson effect is not very well known , in part because it come into being by swallow two other effects . Charles Athanase Peltier discover the Peltier Effect when he noticed that when an electric current was passed through two materials , one cooled and the other hot up . Thomas Johann Seebeck noticed exactly the opposition . When two unlike temperatures were applied to the same materials , a voltage and subsequent electric current grow between them .

William Thomson came in , we can only assume on a white horse , and saw that these were two sides of the same coin . He came up with a elbow room to measure the temperature slope in a single material with a current going through it . Once that is established , it ’s possible to fare up with the gradients of any other stuff . Lead is often used as the baseline for these trial run . It is unremarkably make out as the only metal for which there is no Thomson impression whatsoever . It was only recently that it was indicate to have the barest flickering of a Thomson issue . This is not , necessarily , why Superman ca n’t see through it — but there is a path we can break .

Superconductors , by definition , have no Thomson Effect . These textile , when drop down to temperatures within spitting distance of rank zero , have no electrical resistance . Since it ’s this underground that causes heat , the current flows through a superconductor without ignite it , and its actual Thomson Effect is right at zero .

So if Superman tries , and fails , to reckon through a superconductor , we ’ll know once and for all the reason why he ca n’t see through lead . And maybe that , in turn , will give us a outstanding brainstorm into how Superman ’s superintendent - visual modality really works . Make it happen , DC !
