Save your money . <| sep |> we ' re gettin light rail though and that should mitigate the ' hard to get to ' complaints somewhat . <| sep |> What a piece of shit . I hope his public defender is muslim <| sep |> I loved this article ! Are there articles this indepth for all the personality types ? <| sep |> would have enjoyed the mess . <| sep |> Hahaha , you are a funny cunt . Is that all you can say ? It hardly makes sense . Feeling for you buddy . <| sep |> I would think Trump would agree name calling is childish . <| sep |> Magmar will sometimes spawn at round house park near the hfc <| sep |> Disclaimer RF guy , not an optics guy . I ' m only going to attempt the questions I know anything about . 1 Is visible light inherently visible ? Do some animals or could some aliens have a visible spectrum in a separate section of the electromagnetic spectrum ? Yes , animals can see very different parts of the spectrum . Bees can see into ultrivioletN 1 TUDFCOwjY , for example . Did the human eye evolve to see visible light because it was the only spectrum that is possible to be seen or just because that ' s the spectrum we happen to see ? Not an evolutionary biologist hard pass on this question . 2 Do radio telescopes and infra cameras work the same waywork on the same principle ? I think it depends . Any sensors near the visible spectrum IR and UV probably rely on picking up photons on some kind of camera sensor , like a CCD . A typical radio telescope , however , receives wavelengths that are much longer , typically in the microwave range , and the way they are detected is much different . They rely on large dishes or arrays of dishes to simulate a gigantic aperture akin to a camera lens , except synthesized to be miles across . How far can these cameras see into the RF spectrum ? Are there cameras that see ultra violet light ? Fun fact many DSLR camera sensors can pick up infrared . They have to add a special filter in front to absorb the IR so it doesn ' t muck up your image . Check out what happens when you remove that f i l t e r h o w t o t u r n y o u r d s l r i n t o a f u l lspectrumsupercameraThere are special hyperspectral cameras that can capture a wide swath of spectrum in an instant . Keep in mind when viewing those images is that they are picking up radiation outside what we can normally perceive , so the bandwidth of data captured must be artificially mapped into visible colors that we can interpret . Can wifi signals be visualized ? Not like a visible image , no . You ' d need a gigantic aperture due to the wavelength of wifi , about 12 . 5 cm . It ' s much too large to resolve and focus into an image . See wikipedia articles like this onelimitedsystem and this one . 3 if light signals propagate down fiber optic cables , could RF theoretically travel through specialized fiber optic cables ? Transmission lines like ladder line , coax , waveguide , and microstrip are the RF equivalent , but the physics principles behind them are the same . RF waves that propagate through these transmission lines do so in different modes depending on lots of factors frequency , discontinuities , how the signal is injected into the transmission line , etc . I don ' t know about optics , but I imagine they deal with the same types of tradeoffs and design decisions when using those cables .
