An alternative interpretation of the Grioli gyroscope suspension points
We present a detailed analysis of all possible regular precessions of a heavy asymmetric body with a fixed point not coinciding with the center of mass. The calculations are done in terms of the rotation matrix, by writing the Euler-Poisson equations with all involved vectors parameterized in the Laboratory frame. It is shown that a regular precession is possible if the suspension point is chosen on the straight lines (lying in the principal plane) which are frontiers of the regions where, as t…

Accidental coincidences in camera-based high-dimensional entanglement certification
High-dimensional entangled states, such as spatially-entangled photon pairs produced by Spontaneous Parametric Down-Conversion (SPDC), are a key resource for quantum technologies. In recent years, camera-based coincidence counting approaches have considerably improved the ability to characterize them in terms of speed and dimensionality. However, these methods have limitations, including in most of them the necessity to subtract accidental coincidences. Here, we study the role of these accident…

As Trump's tariffs cut off the US from imports and as he deports the core of the US labor force, I think about the fact that tariffs and other import taxes were a major part of the lead up to the Revolutionary War. It's no coincidence that a bunch of the Founding Fathers were smugglers.
The logistics of the resistance and the logistics of the population were intertwined, meaning that it was not always possible to attack resistance logistics without alienating the population.
All this is worth keeping in mind right now.

May's #employment gain of 144K revised down BY 125K; June's 147K down BY 133K.
That's BY; not TO.
#Labor numbers are often revised but this seems too much, and it fuels distrust. Hard to believe it's incompetence or some freaky coincidence.
