It turned out that I already knew all the facts in this lecture, but Professor Sheehy kept my attention all the way through anyway, and put the narrative together in a very interesting way. Excellent lecture.
This is a part of science that is too often not taught but should be. To understand the history is to understand the way to think when conducting science ,to understand the tools needed to find answers to questions , the methodology, the patience , the danger , the thankless circumstance some people found themselves in, the severe bias towards male recognition. So may aspects of this that are not written in equations or statistical data . Thanks for touching a very small part of this big story .
Whith the X-Ray, the Kay of its rapid spread wasn't his willingness to spread the idea, but his willingness to share it with everyone by not patenting it. The patent system: hampering development one decade at a time.
I am no particular critic of Capitalism, but in 2022 I find it's a particular beautiful thing that Roentgen shared his findings and thus allowed them to be publicly available like this AND, in particular, I FINALLY found what the "Roentgen" scale in the Netflix's show "Chernobyl" actually meant. Honestly, I feel like the late 19th century, early 20th century was when we found the utmost professional people in their field together with people utmostly positive and inspiring. Cheer on this lecture!
The particle physics lesson that people can work together on large problems is really a unique point that I've never heard before. Such a hopeful way of looking at the world, in spite of some pretty major environmental and social issues.
1:46 "...the 20th century in physics was an enormous decade of change." so enormous, in fact, that it seemed as though it could have contained fully ten decades of change !

Amazing lecture Suzie and excellent way of taking a stand on the nature of science and how we have used it and how we should use it. You could have even talked more about the scientist+civilians "sacrificing" or loosing their lives after doing experiences with new inventions etc. Many lives were lost due the lack of safety issues back in the days or just due to not knowing all the side effects etc. Excellent job Suzie. I am very amazed by your work and by your wisdom.
The 1931 giant Van De Graaff generator that now lives in the Museum Of Science Boston was able to reach +5 MV on one sphere and -5 MV on the other, so it could give 10 MeV energies to charged particles and ions. I ran an experiment inside it in 2010; the original wooden workbenches from 1931 were still there.
If I was to predict the future now, I'd make future architecture look more like hobbit holes for rural areas, and artificial hills with forest-cover up top for the urban ones. For we either manage to bring some space for nature back, or we won't have a future.
A very envigorating presentation which leaves me yearning for some more.Am impressed with the additional in depth knowledge she simplified for all enthusiasts to comprehend.
I admire her presentation. It's different and I have to give her credit for making us listen until the end. I get bored with polished presenters. They can talk as long as they stick with the script. There is one man I'm missing, which I'm shore is not presenter's fault, and his name is Nikola Tesla. He was the most prolific inventor and he was particularly able to convert his ideas and lucid dreams into a working product. I can only guess why he was ignored, his lab burned down, car hit, investors turned away when he most needed them There are number of patents and ideas that were copied from him such as; Telegraph, Roentgen tube, rays, harp, death rays, x-rays, scalar longitudinal electric waves, Tesla’s inventions included the following; AC Power (alternating current) Tesla Coil Magnifying Transmitter Tesla Turbine Shadowgraph Radio Neon Lamp Hydroelectric Power Induction Motor Radio Controlled Boat Looking at this list I'd conclude that Tesla breakthrough inventions are the basis for a lot of todays or future inventions. There is a lot of controversies regarding Tesla, but if one is prepared to study his works from various sources, he/ she will learn how much ahead he was and how much more could he participate to humanity if he was not step sided and ignored for 30 years.
One of my favourite experiments is Robert Millikan's where he used an oil drop to determine the mass of the electron. Another modern one is the double slit experiment. Physics is class.
I think that the most amazing thing in this lecture was the last statements. Basically don't disregard an opinion or idea just because the suggester doesn't have a top education and don't just mix with people with your own education and knowledge.
Fascinating! Which made it even better is the speaker. Knowledgeable, loves the topic, and despite the fact that her haircut has more understanding of science and history then I could reach in 3 lifetimes, she still managed to be this lovely character. Kudos!
What a fantastic journey through the discovery of physics..... Fascinating! Well done Suzie for making a difficult subject to understand so accessible. Frankly, I didn't think that this would be an easy watch, but it was well explained and your excitement for science is quite infectious. I'm looking forward to reading your book. Excelsior!!!!!!!
Mrs Richards: "I paid for a room with a view !" Basil: (pointing to the lovely view) "That is Torquay, Madam ." Mrs Richards: "It's not good enough!" Basil: "May I ask what you were expecting to see out of a Torquay hotel bedroom window? Sydney Opera House, perhaps? the Hanging Gardens of Babylon? Herds of wildebeest sweeping majestically past?..." Mrs Richards: "Don't be silly! I expect to be able to see the sea !" Basil: "You can see the sea, it's over there between the land and the sky." Mrs Richards: "I'm not satisfied. But I shall stay. But I expect a reduction." Basil: "Why?! Because Krakatoa's not erupting at the moment ?"
This was a great lecture about history of Experimental Physics, especially Particle Physics, as well as with some criticisms. I think 3 scientific theories are crucial in Quantum Physics, Quantum Entanglement, Quantum Particle and Quantum Mechanics. They are connected with each other, that's why a classical Entanglement tricks the whole system. But it was nice to learn more from Great Minds.
I've just discovered by accident reverb effect improves enormously the sound of the presenter talking. I think RI should add add reverb or slight echo to all their future video soundtracks. .. Edit: Nothing new. .. Just discovered the BBC have used subtle reverb on talking since the 1930's
Great presentation. I appreciate the focus on women's contributions to our fundamental understandings of particle physics -so refreshing. In school, all male but for Mme Curie.
Some of the things she stated as known, are not and are only supposition. When a scientist states we know you should take it as an assumption that may or may not be the best known explanation we currently have. Sometimes it is complete supposition that is not science but scientism.
This is such a great summary! I've never heard the chronology and people involved over this span of time, and that wasn't overshadowed by relativity. Thank you! I would love to just stand at that table and soak in the genius.
Well done. As others have said, hands-on demonstrations of how things were discovered and the people behind these discoveries is fascinating. Thank you RI and Dr. Sheehy.
There is nothing I enjoy more than sparkly scientists. ❤️🔥❤️🔥❤️🔥❤️🔥 The sparklier the better! 🤩💃👍🏻 thanks 🙏🏻 This was extremely interesting and beautiful and helpful. Thank you so much 🥰❤️🔥
"Edison couldn't find a use for it" Wow. Edison, master of making money off other people's inventions, totally misses out on the opportunity to make money off what might be the only thing he invented himself...
Pretty interesting talk. I appreciate the speaker's motivation to point out women's contributions to science that have been popularly ignored. I do think it is worth noticing that in all likelihood, for each one of the women she is pointing out, there are probably dozens of men that history has also ignored. Consider the group photo with Harriet Brooks who the speaker presumes (correctly) that no one in the audience would recognize. How many men are in that same picture that similarly no one could name? I count about seven. That isn't to say women got the recognition they deserved, but that doesn't mean that same thing isn't true for many men too. I wouldn't be surprised if the historical low recognition rate of women in science is similar to the historical low participation rate of women in science, and isn't at all about some misogynistic agenda.
Participation rates would surely have been higher had they been given the same freedoms. Financial support and being able to continue working after marriage for example.
At that time many women weren't even allowed to attend any university. Even Marie Curie had troubles when she went to paris. She was allowed to study, but no one wanted to support her ambitions to become a doctor. She needed to convince Bequerel that she is capeable of.....we know how that story ends. Two Nobelprizes for her and one for her daughter.
Great lecture, captivating presentation! From someone who does listen to those on headphones...pls don't laught at own jokes 😊 as the vol goes up like crazy. Book purchased!
5:38 the underwater breathing apparatii of their day weren't self-contained, so I think that's an accurate prediction. the automation isn't so far off either
Imagine two protons crashing @ an "Exact", 90% angle, to each other, in the beginning of time. With all the chaos of the universe. What do you think happened?
2:42 - This is a bit misleading, namely because it's missing three words. The number she's quoting isn't "the life expectancy of people in 1900", it's the *average* life expectancy *at birth* of people (born) in 1900. Most people alive in 1900 were actually likely to live well past the age of 45 (though two world wars may have skewed that a wee bit ;-). Until the middle of the 20th century, child mortality was over 50% of all mortality. But if you made it past 10, there was a pretty good chance you'd live past 60 (still not as long as nowadays, but the difference isn't quite as huge as saying "the life expectancy of people was 45" suggests).
Agree, too many giggles. I suppose it is natural to be nervous in a venue with such a history. If a woman wants to highlight the contributions or women in science, fewer giggles could help the cause.
What do you think has been the most world-changing physics experiment? Let us know in the comments. You can watch the Q&A for Suzie's talk here: ruclips.net/video/gEHXJEFSftE/видео.html
There are many experiments that led to our understanding of the world. But I think it was the discovery of the electron. As Dr. Sheehy pointed out, it led quickly, and directly to so many things that are now seen as indispensable parts of our everyday lives.
You can do an experiment in your head. Picture motion from all angles, and do so until you understand it fully. In my videos you can see what the outcome is. No physics background education is required to do the same. In short, you can be your own Einstein.
Michelson and Morley only showed that space has no absolute location with which to establish a drift velocity. It didn't prove that light speed was "relative to the observer," but that is how it turned out thanks to the "belief" in what math tells you. So, using math, Relativity changes your data using transform equations so that light speed can become the constant that it is declared to be, even though it don't look constant before the transformation. This means that there is at least one alternative non-transformed theory that is completely ignored. A transform is a number between 0 and 1 that is a scale factor to adjust length, mass, and time to keep light speed c. It is not smarter than that which makes it faith in math after it CHANGED your reality.
Most wonderful channel for the point of great learning it's art of great experience based truth so interesting makes easy day today ..about mostly all fields of faculties like 👍..I am minutely listening yours great study experience..
I never understand who was counted when they tell us life expectancy like in the 1900. My ancestry goes back way further than that and unless they died in infancy or of a farming accident or as soldiers in a war, the vast majority live to be between 75 -80 years of age. Go to an old cemetery in any country in Europe and see how old the deceased were and you'll find, aside from what I have mentioned, they lived to the age of 75-80.
Thanks! I quick question - what is the half- life of a Hydrogen atom, and what is the result? (Since halfing everything must ultimately result in Hydrogen atoms… 😊)
Truly a remarkable presentation!! I read probably my most highly inspirational book by my newfound role model, Fundamentals: The Ten Keys to Reality by Frank Wilczek who he references experiments as well as other interesting findings in this presentation. There’s also the book, QED The Strange Theory of Light and Matter by Richard P. Feynman which this video helps me visualize the x-rays excitements. These all ultimately lead me to a sense of motivation and question as to what’s left to discover? Well I position myself towards LIGO Virgo KAGRA into understanding gravity and gravitational waves. Of course education follows, but for now I am currently reading a booklet called Relativity the 100th anniversary; as instructed I have not proceeded further until I am fully convinced on the requirement needed in chapter 8. For the vitality of humankind.
Not sure if it was an accident or calculated, but delicious showing 1900’s cartoons trying to predict life in the 2000’s, the 2000’s woman didn’t remember what the profession which makes clothes is called… (Tailor.)
After all the years I have been interested in physics, I love finding out new things about how the discoveries were made, and the people involved.
Same here. The difference is that it's my beginning. And I love it. الحمدللہ ❤️

Just a small thing, but our main server at our company is called "Marietta" in honor of Marietta Blau!
It wasn't Alexander Fleming, he discovered penicillin. It was Sir John Ambrose Fleming who invented the Fleming valve.

Life expectancy is very deceiving since most deaths were babies and children in 1900 thus lowering the average! It has not improved drastically since.

Michelson Morley experiment
Electromagnetism - specifically Michael Faraday’s first electric ‘motor’ at the Royal Institution.
You can do an experiment in your head. Picture motion from all angles, and do so until you understand it fully. In my videos you can see what the outcome is. No physics background education is required to do the same. In short, you can be your own Einstein.
Thank you I love you so much 🥰👍🏻

Michelson and Morley only showed that space has no absolute location with which to establish a drift velocity. It didn't prove that light speed was "relative to the observer," but that is how it turned out thanks to the "belief" in what math tells you. So, using math, Relativity changes your data using transform equations so that light speed can become the constant that it is declared to be, even though it don't look constant before the transformation. This means that there is at least one alternative non-transformed theory that is completely ignored. A transform is a number between 0 and 1 that is a scale factor to adjust length, mass, and time to keep light speed c. It is not smarter than that which makes it faith in math after it CHANGED your reality.

Thanks! I quick question - what is the half- life of a Hydrogen atom, and what is the result? (Since halfing everything must ultimately result in Hydrogen atoms… 😊)
We don't know. There is no well established half life for the proton, yet. :-)
Our future is a wave function of probabilities. We just need to collapse it with dignity for all…

Truly a remarkable presentation!! I read probably my most highly inspirational book by my newfound role model, Fundamentals: The Ten Keys to Reality by Frank Wilczek who he references experiments as well as other interesting findings in this presentation. There’s also the book, QED The Strange Theory of Light and Matter by Richard P. Feynman which this video helps me visualize the x-rays excitements.
These all ultimately lead me to a sense of motivation and question as to what’s left to discover?
Well I position myself towards LIGO Virgo KAGRA into understanding gravity and gravitational waves.
Of course education follows, but for now I am currently reading a booklet called Relativity the 100th anniversary; as instructed I have not proceeded further until I am fully convinced on the requirement needed in chapter 8.
For the vitality of humankind.
Curiosity and serendipidity
I miss the invention of laser and what it means today
You know laughing is a great thing but it's distracting for the audience if the speaker often laughs during a speech for no reason
when physics get political , very true ma'am
They did play golf on the moon though
Why we exist? That's the main topic in physics so we know Why we exist
