Good opportunity today to use my macro:

Why do you think that? From what I see, there's no use of actual biological material in the course...

I can try and answer these... The flow rate is (most likely) driven by the rate of rainfall, and my colleague, and environmental...

This is a sample of an ultramafic rock: I think this is either a phlogopite-hornblende-olivine peridotite or a pyroxene peridotite-...

Asking on behalf of a colleague who is studying rainwater transport/drainage in the context of plants (trees, mostly): There's a lot of...

Now I understand why you keep insisting on gaussian beams. I'm sorry, but this does not demonstrate to me that you can evaluate basic...

I'm concerned we are not making progress here. To proceed, I need to know that you can evaluate the Fourier integral...

The Blowdryer Galaxy (a.k.a., M100, NGC 4321, Mirror Galaxy), imaged from my back patio, March-April 2024. The galaxy is about 56...

Be careful- the FT does not just happen, it is a consequence of Fraunhofer's approximation to the Rayleigh-Sommerfeld diffraction...

I don't know what you mean by "real understanding". A lens doesn't always perform a Fourier transform. What a lens *can* do is bring...

I think this is making the situation too complex: light reflecting off a mirror is an example of an elastic collision, for example.

Unfortunately, the comet is too close to the horizon line (here).

Maybe it would help to think of "the far field" as Fourier transform space (equivalent to 'k-space' in scattering) of the object plane...

I had a chance to take a few careful images of arfvedsonite crystals today, I think I found an arrangement with both 'head cut' and...
