I guess I was sort of thinking about them as a particle instead of a wave. But duh this makes total sense. Shows how sensitive these machines were.

So the wavelength is so large that the wave might encompass half of earth? So there was a chance per say that only one site could detect the wave because the two sites were thousands of miles apart?

I have a question about how they were able to detect the gravitational wave. They say they have two different sites approx. 4000 km away from one another. If the size of the wave is one tenth of a electron-mass how did both sites detect the wave came through?

This is also example 3.4 in Griffiths E&M. He just breezes over the Fourier analysis part saying its the same as example 3.3 which is in this photo. However my cosh term doesn't cancel so I'm not just left with the sine term?

I drew it terribly above but you catch my drift.

Thanks but this is math I am completely unfamiliar with. It ended up being doable also with a contour integral. SOLVED.

1. The answer to this problem is easy when plugged into mathematica it's (pi^2)/3. I am trying to integrate it by hand however and can't figure out how to start it. I also can't find any other attempts of it online (our professor says we can just look it up if we can find it). [(x^2*E^x)/(E^x...

Homework Statement [/B] Just trying to find the spin 3/2 rotation matrix, I've found spin 1/2 and spin 1. This isn't a homework problem just studying some other spins. Homework Equations For spin 1/2: Rn(Φ) = cos(Φ/2)1ˆ − isin(Φ/2)σn For spin 1: Un(Φ) = e −iΦSn = 1ˆ − isin(Φ) · Sn − (1ˆ −...
