Thought provoking and entertaining - thanks to the RI for sharing
Very 1st lesson I was told about computers was "sh@# in = sh@# out" 40 years later and it also applies to AI.
GIGO
Are you a plumber?
I don't get that point about smoking and Alzheimers, most studies I've seen report that smoking increases the risk of dementia.
love it

4 minutes in, still doing the autobiography. Skip to 7:22, still talking in the first person. Just my opinion: That's too much me, me, me. I don't know who you are, just give me the facts you came to share.
Yep. Noticed that too...was looking forward to a hopefully enlightening lecture/discussion...Minutes upon minutes of unnecessary and interminably boring waffle which could have easily been referred to in a linked biography.
An AI chatbot would've been more interesting IMO.
Gonna pass and hope for more engaging future talks on data science.
"I don't know who you are..." Well, that's why she's telling you who she is.
@@ultraviolet.catastrophe You think I might be more interested in who she js if she just gave me some useful information that made me watch the entire video?
The channel is declining. First was to restrict Q&A to members only (as if that was the primary objective of the channel, i.e., generating money instead of sharing knowledge). Now they have chosen to post videos of narcissists, who think the most important thing is to talk about themselves and their collaborators. Ideas are much more important than the people who had them, since the former are temporary and the latter last much longer, and they are the ones that really matter to humanity. Faraday must be in high rpm in the grave.
Wow Brian , coffee huh !?
❤❤❤
So you don't care about disclosing US crimes ??? ?
I have never zoomed so intensely on a video. Her earrings are so pretty.
Exactly right in The end abt inherent determinism problem in all modern systems and people using them. A learning problem... But for many the damage is done.
Especially if facing a conflicting motif or error. Which there are plenty... Structural, intentional or unintentional. Explicit or implicit.
Too much rambling and talking about herself.
Please stick to the subject, start from the beginning, don't assume that your audience are already experts.
Let's talk about me and my career!
Made it until 5 minutes in. That's when the gender talk started. Can't we just talk about the topic at hand for once? It's pretty sad.
Agree. Also didn't like her comment about the university she works at now is a lot more "political"... geez... pretty sure that doesn't affect her impartiality / findings. 🙄
Also seems to really miss the Covid hysteria times.
She's a bit too much "Ministry of Truth" for my liking.
About the focus on gender: As a man, I am sick and tired of the insinuation that it's somehow my gender's fault that not enough girls go into STEM.
In my first year of engineering (1983), there were 500 students and maybe 20-25 of them were girls. I would have LOVED to have 50 percent girls... for one, it would've made the parties a lot more interesting, but also because women approach problems differently than men and having different approaches come together is so enriching and powerful.
I have worked with quite a few female engineers and scientists over the years and many (not all) can run circles around the men.
I tried very hard to make my daughter go into the STEM field... and it pains me to say that I wasn't successful. I know she would have been great.
@@JohnWoods-n8l My daughter also scored ridiculously high in STEM evaluation. Top 1%. So yes, she can do it, but she has no interest in it. I tried to get her to consider it as a career but she thinks the whole thing is BORING to death. She went into theater, and is super happy. Loves her job every single day. We have to stop trying to shoehorn OTHER people into places WE think they should go.
She is not good at explaining in simplicity
Especially when you follow the normal information that is not probable but speculation that is pushed by the norm. Magnetism is a force of pressure equalization to distance traveling. Space is a weak external magnetic field filled with dark heat energy outside of entanglement of mass as potential renewable heat energy when entanglement with mass occurs. Earth's internal magnetic field grounding currents through its core or nucleus is absolute fact. Heat currents grounding of renewable incoming heat energy and outgoing heat energy currents grounding to surrounding gasses and earth's internal magnetic field synchronization of quantum magnetic fields as force of pressure known as bonding currents as force of weight. The closer to the core of a magnetic field, cycling circulation is the strongest force of pressure. Force is always equalization to distance traveling cycling circulation patterns as mass in and out of entanglement of mass. Repulsion of occupational space as neutralized repulsion within mass as outward force of pressure outside of a greater internal magnetic field grounding currents like earth's internal magnetic field as weightless. Mass occupies equalization of space itself as cold repulsion within mass and repulsion without mass equalization to force and distance traveling. Mass falls in equalization to repulsion within and without. As mass moves away from earth's internal magnetic field, distance traveling increases, and force of pressure known as weight decreases. Heat currents grounding towards earth's greater internal magnetic field. Electricity is rapid heat exchanging through mass as renewable heat energy grounding currents towards earth's internal magnetic field as synchronized flow of pressure cycling circulation patterns as quantum internal magnetic fields grounding currents through the nucleus or core where force is strongest. External magnetic fields don't ground currents through the nucleus or core but circulation around these monopoles of pure repulsion as magnetic field generators that spin all external heat energy within its magnetic field. As mass expands, its magnetic field expands and weakens. Hydrogen has the strongest internal magnetic field grounding currents of the elements. Hydrogen under extreme pressure expands into helium and contains more heat energy currents grounding than hydrogen and occupies more cold space within. More energy equalization to more cold repulsion within and without entanglement of mass. Light is only present in resistance to mass as renewable heat energy unabsorbed bouncing off mass as striking sparks of electrons as friction lighting up surrounding atmospheres. External heat energy outside of entanglement of mass in space and atmospheres outside of entanglement of mass as potential renewable heat energy when entanglement with mass absorption. Unabsorbed heat singularities striking sparks of friction lighting up surrounding atmospheres. Heat magnification of refraction as light sparks known as electrons. Heat is the lifeblood of everything throughout space and mass as the only renewable source of energy within and without entanglement of mass. Physics works. Hydrogen occupies space as mass. Cold repulsion within mass is an outward force of pressure as heat propulsion momentum from cold repulsion within and without entanglement of mass in equalization to force of pressure and distance traveling. Hydrogen has the strongest force of pressure and minimum distance traveling cycling circulation patterns as mass. Helium has more heat energy currents grounding and occupies more space in equalization to force and distance traveling cycling circulation. Repulsion increases in equalization to mass as an area of repulsion. More mass, occupational space, and current grounding. Impaction of force increases, and distance traveling decreases. Force decreases in equalization to distance traveling, which increases within and without entanglement of mass. Magnetism works for physics without gravity. Theoretically factual probability that works with quantum physics without gravity.
Your text exhibits certain characteristics that might raise questions about your mental state due to its highly abstract, intricate, and somewhat non-linear nature. Here are some potential psychological symptoms that might be inferred from such a writing style, although this is speculative and not diagnostic:
Disorganized Thinking:
The text jumps between concepts without clear transitions, which might suggest disorganized thought processes. This can sometimes be associated with certain mental health conditions, such as schizophrenia or bipolar disorder during manic episodes.
Grandiosity:
The attempt to explain complex universal phenomena in an unconventional way might indicate a sense of grandiosity, which can be a symptom of manic episodes in bipolar disorder.
Flight of Ideas:
The rapid shift from one idea to another without clear connections could be indicative of flight of ideas, a symptom often associated with mania.
Obsessive Focus:
The intense focus on a specific, highly abstract topic might suggest obsessive tendencies, which can be seen in various mental health conditions, including obsessive-compulsive disorder (OCD) or certain personality disorders.
Magical Thinking:
The blending of scientific concepts with speculative, almost mystical ideas could be seen as a form of magical thinking, which is sometimes observed in schizotypal personality disorder.
Paranoia or Delusional Thinking:
If the ideas presented were strongly believed despite contradicting established scientific understanding, it could hint at delusional thinking, a symptom of several psychiatric conditions.

Maybe you should talk at the RI.
Poor, me me me me me
First RI video that I couldn't watch until the end. She talked way too much about herself and biking. I stopped 16 minutes in.
