2023 full connectome published on Science by Marta Zlatic's lab at the MRC:

The hard part then is how to make any predictions from it:

2024: www.nature.com/articles/d41586-024-03190-y Largest brain map ever reveals fruit fly's neurons in exquisite detail

As of 2022, it had been almost fully decoded by post mortem connectome extraction with microtome!!! 135k neurons.

That article mentions the humongous paper elifesciences.org/articles/66039 elifesciences.org/articles/66039 "A connectome of the Drosophila central complex reveals network motifs suitable for flexible navigation and context-dependent action selection" by a group from Janelia Research Campus. THe paper is so large that it makes eLife hang.

Observation that all solids appear to have the same constant heat capacity per mole.

It can be seen as the limit case of an Einstein solid at high temperatures. At lower temperatures, the heat capacity depends on temperature.

Step of electronic design automation that maps the register transfer level input (e.g. Verilog) to a standard cell library.

The output of this step is another Verilog file, but one that exclusively uses interlinked cell library components.

Gene overview:

This section is about the definition of the dot product over ${\mathbb{C}}^n$, which extends the definition of the dot product over ${\mathbb{R}}^n$.

Some motivation is discussed at: math.stackexchange.com/questions/2459814/what-is-the-dot-product-of-complex-vectors/4300169#4300169

The complex dot product is defined as:

E.g. in ${\mathbb{C}}^1$:

We can see therefore that this is a form, and a positive definite because:

Just like the usual dot product, this will be a positive definite symmetric bilinear form by definition.

In the context of Maxwell's equations, it is vector field that is one of the inputs of the equation.

Section "Maxwell's equations with pointlike particles" asks if the theory would work for pointlike particles in order to predict the evolution of this field as part of the equations themselves rather than as an external element.

Measured in amperes in the International System of Units.

For some reason Chinese people (and their sphere of influence such as Japan) are obsessed by numbered lists, e.g. stuff like Four Beauties, Four Treasures of the Study and so on!

The concept does exist in the West (e.g. The Seven Wonders of the World), but clearly the Sinosphere is much more obsesse by it!

Lit. "to kick (leather) ball".

Figures notbaly in Water Margin, where it is played by Gao Qiu. The novel also suggests that it was considered a lesser art, e.g. as opposed to the scholarly four arts and the "proper" martial arts.
