What would you recommend as a supplement to Shilov's LA book?
epsilonic · 2 days ago
Linear Algebra and Geometry by Igor Shafarevich, coupled with Linear Algebra by Friedberg, Insel, and Spence; the latter has great problems to work with, whereas the former is for a lucid exposition.

> I highly doubt there'll ever be research in this area, but I'm very curious about whether it'll ever be possible to induce schizophrenia for a time, similar to how psychedelics or dissociatives can induce altered mind states.

It is not possible, by definition; here’s a portion of the DSM 5 definition of schizophrenia:

“ The disturbance is not attributable to the physiological effects of a substance (e.g., a drug of abuse, a medication) or another medical condition”

Hard to find a publicly accessible DSM link, but here is an excerpt

Man, this article is incredible. So many ideas resonate with me, but I never can't formulate them. Thanks for sharing, all my friends have to read this.

If you like this article, you’ll probably enjoy reading most publications from the Santa Fe Institute.

Exogenous ketone supplementation? Are you drinking acetone or something?
epsilonic · 9 months ago
Not quite. I've been taking Beta-hydroxybutyrate (BHB) salts in powder form, mixed with water. Here is some interesting literature discussing its benefits as a metabolic regulator of proteostasis in aged and Alzheimer-diseased brains:

https://pubmed.ncbi.nlm.nih.gov/37461525/ (same research article referenced in the post link)

I personally take it to manage brain fog due to long-Covid.

As someone currently on a strict ketogenic diet (gotta cut and get ready for the Christmas fattening)

I can say ketones are something else in the brain. I sat at my desk today for 6 hours straight without even getting so much as a drink of water. I didn't even think about eating. Just in the zone and hyper focused.

A very weird and pleasant experience, that alas can't be sustained forever given how delicious carbs are.

This is something I've been experiencing as well, and I just started exogenous Ketone supplementation three days ago.

'plunges', 'alarming speed', 'The shocking incident' but in the end 'none of the passengers or crew aboard the 197-seat aircraft were harmed'

Once again we have a non-story overflowing with hyperbole. These types of articles increase unreasonable fear and do an injustice to journalism. I am flat out done with bad journalism that gets its viewership by hyping fear. 'The Standard' is off my list of credible news outlets.

Yeah… let’s just strap you to a plunging plane, then invalidate your experience as “overflowing with hyperbole”.

What are some good resources (books/papers/videos/etc.) to get started on "Complex Systems", "Emergence", "Self-Organization" and related topics?

Anything by John H. Holland is good.

“It's important to understand that in order to make people superfluous, machines will not have to surpass them in general intelligence but only in certain specialized kinds of intelligence. For example, the machines will not have to create or understand art, music, or literature, they will not need the ability to carry on an intelligent, non-technical conversation (the "Turing test"[18]), they will not have to exercise tact or understand human nature, because these skills will have no application if humans are to be eliminated anyway. To make humans superfluous, the machines will only need to outperform them in making the technical decisions that have to be made for the purpose of promoting the short-term survival and propagation of the dominant self-propagating systems.”
epsilonic commented on Single atom defect in 2D material can hold quantum information at room temp   phys.org/news/2024-05-sci... · Posted by u/westurner

To provide some context:

- Usually the problem with room temperature is that the various thermal mechanical excitation and thermal radiation surrounding the qubit lead to interaction with the qubit and the information stored in it "leaks"; that is the main reason a lot of quantum hardware needs cryogenics.

- There are already a couple of similar types of "defects" that are known as a promising way to retain superposition states at room temperature. They work because the defect happens to be mechanically and/or optically isolated from the rest of the environment due to some idiosyncrasies in its physical composition.

- You might have heard of "trapped ion" or "trapped neutral atom" quantum hardware. In those the qubits are atoms (or the electrons of atoms) and they are trapped (with optical or RF tweezers) so they are kept accessible. The type of "defects" discussed here are "simply" atoms trapped in a crystal lattice instead of trapped in optical tweezers -- there are various tradeoffs for that choice.

- While discoveries like this are extremely exciting, there is a completely separate set of issues about scalability, reliability, longevity, controlability, and reproducible fabrication of devices like this. That is true for any quantum hardware and while there are great improvements over the last 15 years and while there is truly exponential progress over that time, we are still below the threshold of this technology being engineeringly and economically useful.

Lastly, the usual reminder: there are a few problems in computing, communication, and sensing, where quantum devices can do things that are impossible classically, but these are very restricted and niche problems. For most things a classical device is not only practically better today, but also is in-principle better even if quantum computers become trivial to build.

What class of problems benefit significantly from being solved by quantum devices?
