AFM probes can be made thin, which defines relatively small spring constants in the 0.01 - 0.6 N/m range. These AFM probes are regularly used for imaging in contact mode and applied to SOFT samples.
Spring constants of commercial AFM probes vary in the 0.1 N/m to 600 N/m range. Typical dimensions of Si AFM tips are: height 8 - 20 µm, opening angle of ca. 30 - 40 degrees, apex radius 10 nm. They have a pyramidal shape, which in the ideal case should be triangular near the apex.

What if there is, yes, a quality of inwardness to the mind, not because the mind is located inside us (inside our body or brain), but because we are situated, bodily, inside it—because our lives and our thoughts unfold in the depths of a mind that is not really ours, but is rather the Earth’s? What if like the hunkered owl, and the spruce bending
