Actually, as a control systems engineer, Lyapunov was the first one I thought of. You may not know this, but his works were not available in english at that time. Kalman had to read the french translation, as you can see in this 1960 paper titled Control system analysis and design via the “second method” of Lyapunov

Didn't realize that. Propaganda or not, I've found that the usual story about the space race leaves out those two crucial contributions of Tsiolkovsky and Lyapunov. I thought it was more of a cold war thing...

I believe you are missing two major developments that were led by the russians: First, the contributions of Konstantin Tsiolkovsky, whose works on rocket design and fuel mix ("Exploration of Outer Space by Means of Rocket Device", parts 1 and 2) laid the foundations of what we use today. Second, Aleksandr Lyapunov who develped and advanced theory of stability in his doctoral thesis in 1892.

According to my college professor, in the 1950's US engineers didn't bother to check russian publications on any subject, because they, just like you, thought that they were ignorant peasants that had nothing to contribute. Therefore they were completely ignorant about Lyapunov's developments. The thing is that Lyapunov's stability was a key advantage that allowed the soviets to beat the US in launching the first satellite into orbit. Only then, Kalman and others began to read their papers.

By the way, the first International Federation of Automatic Control (IFAC) World Congress, was held in 1960 in Moscow.

PS: I have no preference for any country whatsoever. On the contrary, I believe that excellence in science and engineering can and do arise in many places around the world. In this context, there is no point in dismissing the russians or any other country/place.

PS2: The US response to the Sputnik crisis led to the creation of ARPA, which without any doubt has fueled the US hegemony for decades. Quite an achievement.

I'm sorry for your situation. I certainly cannot imagine what you are going through. At the risk of sounding impertinent --you have most certainly searched areound for the best possible treatment-- I'll share with you an article that sounded like science fiction to me, but that is a real thing: Medicine Spares Cancer Patients From Grisly Surgeries and Harsh Therapies

This is my summary:

"Immunotherapy is a treatment that until now has been used as part of a suite of tools to attack cancer. Basically, it's a strategy that helps the immune system attack cancer cells.

This trial, conducted at the Memorial Sloan Kettering Cancer Center in New York, focused on patients with cancers that normally respond well to immunotherapy treatments, which comprise 2 to 3 percent of patients with cancerous tumors. The novelty is that only immunotherapy was used, without chemotherapy or surgery, using a drug called dostarlimab.

Of the 103 patients in this trial, 98 were completely cured with the first treatment. Of the 5 cases in which the cancer returned, 4 were completely cured with additional doses of immunotherapy, while in the 5th case, the tumor shrank but did not disappear."

The problem with this approach it that setting it too high may discourage skilled people in low income countries to contribute. The key is to find the right balance. Why not begin low and see if it works? You can increase it in small steps later until you reach the desired effect.

A very strict indicator that correlates with quality of healthcare is life expectancy, and according to Our World in Data , the US performance is very bad.

As you can see in the kinked chart, US life expectancy is 79.3 years for a per-capita health expenditure of $ 10,827 (PPP based on 2015 prices). Chile, for example, has a life expectancy of 81.17 years, spending $ 2,453 per capita. That's less than 23% compared to the US.

;-) Thanks

Yeah, I've read good things about Brother too. But with so many fake reviews out there, it is still relevant for me to confirm those revews here. Thank you.

Thanks.

Thank you for sharing this tip. it's brilliant! Not just for lectures, but for many other use cases as well. Bookmarks, links sent by messaging apps, you name it.

The training is just the tip of the iceberg. The underlying assumption is that autonomous systems "capture information from the environment", and this is completely wrong. The training --with labeled data-- takes the Shannon model at face value and simulates an environment that is sending messages tio the autonomous system. But then, when the system operates out in the wild, there is no tag in the images, so it resorts to pattern recognition. Those of you who know that error correction is a key aspect of Shannon's work can recognize that pattern recognition does not have anything remotely similar, so the confidence level on identifying an object or situation varies significantly along the way, sometimes catastrophically.

I lived there for two years, and i never ever got a spam call and never heard anyone complaining about it. I'm not sure what is that they that makes a difference, but it can't be something very esoteric or authoritarian. They are after all a very stable western democracy.
