If I take you seriously, no astronomer could do science until photography
was used to record the images--unless a pen, pencil or chalk is a
mechanical recording device. Eyeballing a spectrum in the absence of a
recording device cannot be science. Objectivity does not inhere in the
apparatus, as the N-ray episode with its many published reports should
demonstrate. Recall also the cold fusion episode. Somebody's instruments
were measuring something that no one else could duplicate But the
original observations were as objective as instruments could provide.
There's a broader basis to science than recording instruments.
