I remember in my sociology class at college there was a section about the behavior of mobs and collective mindset that occurs. It was fascinating discussion and provides me insight in to what is happening right now. It's not as cut and dry (and making broad brush statements) as - "people should peacefully protest and not set fire to and destroy businesses in their neighborhoods, they only hurt themselves when they do that."

I like my local weatherperson to be a true meterologist, a person who can break down millibars like Homer Simpson can wax poetic about sprinkles on donuts. Someone you know, because they are so nerdy about weather, will be giving you the best weather forecast available. But dayum! some meteorologists are not just nerdy and nerdy looking, but also sort of creepy. At least a guy in my neck of the woods is creepy (creepy af in fact). Someone check that dude's basement or refrigerator for jars filled with....

1 hour to go nerds! Ya watching? Probably not. I bet soup to nuts you don't even know what I'm talking about and had to google it. Lie to me and tell me you knew what I was talking about. Go on then, lie like that bad rug you have covering the meth cook mistake you made a few months ago, go on, lie, I dare ya.

'A "beyond-quantum" equivalence principle for superposition and entanglement
[...] Both superposition and entanglement are described mathematically by quantum theory. But many physicists believe that the ultimate theory of reality may lie beyond quantum theory. Now, a team of physicists and mathematicians has discovered a new connection between these two weird properties that does not assume that quantum theory is correct. [...]
"We were really excited to find this new connection that goes beyond quantum theory because the connection will be valid even for more exotic theories that are yet to be discovered," [...] "This is also important because it is independent of the mathematical formalism of quantum theory and uses only notions with an immediate operational interpretation," [...]
[...]
The problem is that to find out you need to analyze superposition and entanglement in terms of some general–and as yet unknown–theory, without using the mathematics of quantum theory. How can you do that? [...] solved this puzzle by studying "general probabilistic theories," rather than quantum theory. [...]
[...] two physical theories exhibit entanglement when combined, if and only if they both exhibit local superpositions. This means that entanglement and superposition are equivalent in any physical theory, not just in quantum theory. They also calculated that in systems where this equivalence holds–whether quantum or beyond-quantum–the laws of the theory can be exploited for ultra-secure encryption. In particular, the team showed that a certain popular quantum cryptographic protocol, known as "BB84," will always work–even if one day it is found that quantum theory is not fully correct, and needs to be replaced with a more fundamental theory.
"It is somehow reassuring to know that cryptography is really a feature of all non-classical theories, and not just a quantum oddity, since many of us believe that the ultimate theory of nature will likely be non-classical,"'

'New brain learning mechanism calls for revision of long-held neuroscience hypothesis
[...] one single neuron can realize deep learning algorithms, which previously required an artificial complex network consisting of thousands of connected neurons. This discovery is expected to have important implications on future AI hardware.
[...] the brain learns completely differently than has been assumed since the 20th century. The new experimental observations suggest that learning is mainly performed in neuronal dendritic trees, where the trunk and branches of the tree modify their strength, as opposed to modifying solely the strength of the synapses (dendritic leaves), as was previously thought. These observations also indicate that the neuron is actually a much more complex, dynamic and computational element than a binary element that can fire or not. Just one single neuron can realize deep learning algorithms, which previously required an artificial complex network consisting of thousands of connected neurons and synapses.
"We've shown that efficient learning on dendritic trees of a single neuron can artificially achieve success rates approaching unity for handwritten digit recognition. This finding paves the way for an efficient biologically inspired new type of AI hardware and algorithms," [...] "This simplified learning mechanism represents a step towards a plausible biological realization of backpropagation algorithms, which are currently the central technique in AI,"'

'We Might Be Treating Schizophrenia All Wrong
[...] doctors treated the symptoms of schizophrenia[...] with antipsychotic medications. Prevailing theories suggest that elevated dopamine signaling in the brain leads to schizophrenia, so these antipsychotics provide relief by tempering dopamine activity. [...] these drugs impact other parts of the body and foster unwanted side effects including weight gain, constipation, and drowsiness. On top of that, more than nearly a third of patients don't even respond to two or more common antipsychotic treatments.
[...] new study run by researchers in Japan and published earlier this year in Cell Reports Medicine suggests that for at least a significant portion of patients, the immune system is mistakenly attacking a protein in the brain—which may be the real mechanism giving rise to schizophrenic symptoms in the first place.'

Tried this with roasted hazelnuts. Definitely tasted more flavors, but... those extra flavors seemed less pleasant, and detracted from my enjoyment. Could partly be lack of familiarity, though I'm generally very open to unfamiliar flavors, so probably not. Ambient anxiety about food falling out of my mouth and attracting flies---or flies entering my open mouth---could also be contributing....

Yeah, I think wine culture of the aughts era got the entertainment abbreviated version of wine tasting in that film. One of my sisters and her husband are total wine snobs. They used to be subscribed to a wine of the month type deal, but not anymore (expensive hobby, and they had just started a family). Anyway, the clip from the movie doesn't mention the 'legs' of the wine, which is something my sister's husband would proudly exhibit when examining the wine he had just poured for us. I believe the description of a vintage's legs is wine 101 type stuff. The film does get positive marks from wine enthusiasts though. Some of my coworkers are wine fans and they recall pleasant memories from the movie. I think it endears well with the wine demo that has traveled and done the California wine tours, which my sister and her husband have. The film is supposed to have done an excellent job in capturing the location and scenery of California wine country.
