Fourier transform is mostly for EE guy stuff so it must be correct even on a tough guy’s arm. omega and f can be understood as interchangeable each other, but omega is still 2*pi*f and requires integral’s limit so the equation must be correct whatsoever. j would also be look much better than i……Can he show his another arm for DFT verification?

Uh… the equation is fine. If you were actually comfortable with the Fourier transform you could care less if he used \omega or \xi. The domain being left off is fine too – how do you know it isn’t R^n?

lol^ the +- infinity can still be added. And stop hating for stupid reasons

Agreed: angular frequency (omega) = 2*pi*f. The 2*pi on the tattoo is redundant. It would actually make the exponent 4*(pi^2)*f*i*x as it is seen.

Also agreed: you need the limits of integration. Why wouldn’t you include those?! It would “look cooler”, which is the whole point of this tattoo, right? To “look cool”?

Come on, dude. If you are going to be a math know-it-all-show-off… GET THE EQUATION CORRECT!

BTW, the backward hat and wife beater are soooo 1990s. ;)

The i should be a j. That’s the EE in me talking, though.

…personally I’d have had a slightly smaller one; I mean, it’s not exactly discrete is it?

Boom boom ttsssss

….. by the way fantastic tatoo!!

not to be pedantic, but the fourier transform need the boundary in the integral…. minus, plus infinitive…..

omega is angular frequency 10 times out of 10. this guy looks retarded with the 2*pi*omega

Nice idea with the tatoo!
Guys, he just used omega instead of f (if you look at the beginning, it’s G(w) and not G(f) ). Mathematically speaking, you can use sheeps instead of ‘f’, as long as you replace it everywhere.
For the other thing you argue about – integral’s limits. If not specified, it’s assumed to be -inf to +inf.

It looks well. It will definitely attract your children into physics really early. Or make them hate it really early, as well :P

EE dude, you must be an engineer (oh… it just occurred to me that EE must stand for “electrical engineer”). Mathematicians tend to be fine with using omega in either context. In fact, we tend to allow for arbitrary scaling of variables. But I love the tatoo.

Dude, Nice tattoo, and if you were really drunk at the time you made it, it´s quite understandable the “misstake” at the omega instead the f… really freaking geek tattoo… and very cool!! haha peace out!

so this guy decided to use omega instead of “f”? bad call. omega is conveniently the symbol used for angular frequency and is probably used more commonly than “f” in transforms. i also probably would’ve used “j” instead of “i”, but thats just me :P

I understand the dude. I myself drive around with a vanity plate that says, “Fourier”. Honest. But I’m still searching for a portrait of Bracewell for my living room.

the limits of integration are pretty important, though
