    Not exactly. I'm an student of the wonderful world of observable science - electronics, optics, chemistry, computer science, robotics, etc. I'm also not Jesse Z who is an honest to goodness surveyor. Earlier this year when a new real-life...

    You're a geodetic surveyor, right?

    I've been thinking about trying one of these except using a clear rubber tube with colored water and a sight-length of 57.3 inches instead of cm for better accuracy. (Even 57 & 1/4 inches would be fine if one can't find the 1/3rd mark on their...

    Australia Fire Season is usually late spring to Early Autumn, November to February. However Australia has had an extreme drought for the past few year s meaning there is a huge amount of dry combustible materials lying around. This is combined...

    Yesterday (Tuesday 12th November) the New South Wales Government listed the fire danger as “catastrophic”, which is the first time that danger earning has been used. Although not exactly a conspiracy theory, there right wing folks on the radio...

    I wasn't suggesting some kind of horizon obscuration experiment though - you would still have refraction issues with that. I was suggesting the Wallace experiment.

    Theoretically, I think, that would make the thicker ice higher than the thinner ice, as it's buoyant, and so would have a percentage of its thickness above the water level. The advantage of a frozen lake is that you can walk on it, maybe even...

    I gotta run at the moment, maybe I can draw a diagram later. But I envision that as the lake freezes, the shallow parts near the shore may freeze solid all the way down to the ground. That part won't settle. And that's probably the part the...

    An orthogonal thought - the ice sheet on a lake surface is unlikely to have a uniform thickness.
