Like.
I believe you mean Steve McQueen -
Rrenormalize replied to the thread Graduate Some derivation in QFT in Curved SpaceTime by Birrell and Davies.No, because your last equation for ##\Delta\tau## is wrong since it contradicts B&D's eq. (3.57). Remember that ##t## is coordinate time...

Rrenormalize reacted to Demystifier's post in the thread Undergrad The imaginary part of the wave function with Like.
I have never seen that in any book. Unless you mean the drawing of the wave function, it's difficult to draw a complex function, so...

Rrenormalize reacted to hedgehug's post in the thread Undergrad Does the scale factor need to be normalized? with Like.
Yup https://en.wikipedia.org/wiki/Scale_factor_(cosmology)#Detail This definition definitely requires ##a(t_0)=1##.
