- Discussion of a looming “quantum anomaly” in transistor physics that must be solved before major leaps in computation can occur, with speculation that the breakthrough may come from computer-science–first explanations rooted in mathematics rather than traditional physics or manufacturing advances.  
- A Nature paper on high-resolution, non-destructive 3-D imaging of integrated circuits (doi:10.1038/nature21698) was shared via Sci-Hub, highlighting PXCT (Ptychographic X-ray Computed Tomography) as a key technique.  
- Explanation of PXCT: by collecting coherent speckle interference patterns while rotating and translating the sample, iterative algorithms reconstruct a full 3-D density map whose resolution is limited by noise in the outermost speckle features rather than by beam or step size.  
- Critique of current volumetric-data visualization practices—default OpenGL isosurfaces discard bit-depth—contrasted with Siemens’ “Cinematic Volume Rendering Technique,” an example of physically based lighting that conveys richer information.  
- Reference to ptychography more broadly as a computational microscopy method that stitches together many diffraction patterns to achieve super-resolution imaging without lenses.
