Frances, no idea if that was your first time speaking in public, but if it was, congratulations on top of congratulations for an already interesting and hugely informative presentation. I learned more details than I'd ever been able to learn previously about the belts.
Not surprised but still staggered and extremely proud of the unbelievable delivery of this lecture. There are few things that will gain you this level of instant respect as presenting in such a prestigious space. Congratulations! x
Space electronics (along with military electronics) has not followed the trend toward downward size as much as ordinary equipment for that very reason. It is "radiation hardened" by necessity.
Great and inciteful talk for us general public space aficionados. Space radiation is one of the chief problems we must solve if we are going to become a spacefaring species.
This and artificial gravity. Detriments of radiation maybe a bit more long term, but little to no gravity drastically effects the body in quite short order. Both are primary problems that must be solved.
Thank you Ri and Frances for the efforts. This was really interesting. And to the haters, she did very well. You go and try to explain things in front of an audience. Sigh.
2:11 pandemic influenza in the UK [today] is rated as having a higher impact than coastal flooding (lower chance than the flu) or a VOLCANIC ERUPTION (same high chance as the flu)?
@@chrisparkin6894 Ahh... d*mn, you're right. I don't remember why I was looking at the question as local-vs.-global, but I completely skipped distance effects. Yup, I'm gonna need a Jedi mind trick now for anyone who's read this. :-D That still leaves one problem though: their chart then contains local items and suddenly jumps to the non-sequitur of volcanoes occurring elsewhere (unless they mean that all of the other problems are considered to occur elsewhere as well, and the impacts indirectly cascade).
So this talk is saying we need production of electronics such as the 1st Evil Empire developed after the second? Not because it was the best but because it was durable?
Solar plasma is accelerated owing to the nonuniformity of the solar magnetic fields in the solar spots. These solar spots containing helium are colder and have higher magnetic fields than the solar magnetic field. The intensity and the number of these solar spots increases during solar maxima so do their magnetic fields that accelerate the solar particles up to 10,000 km/sec.
The ISS is just under Earth's magnetospheres limit so the astronauts are still kinda safe there but when they'll leave for Mars (if they ever leave) it'll be a total radiation shower... NASA's video on the subject has barely 5k - 10k views... :s
kristian birkeland was egnored and is still not fully recognized nor understood. "magnetic flux ropes" are electric currents along a magnetic field and are named birkeland currents. it is very hard for an astrophysicist to say the word electric. they will talk of "winds in the vaccum of space"... It seems to be a natural consequence of our points of view to assume that the whole of space is filled with electrons and flying electric ions of all kinds. Kristian Birkeland
MilSpec is the new standard. Think pan-galactic humanity going forward. Our current society has almost zero resilience, redundancy, or recuperation of infrastructure based on a myopic just-in-time profit-fetish ‘tude that leaves no room for error of the unexpected {even the expected is dismissed}. This must change.
Ever spoken in front of a large audience? It's nerve wracking! All those people staring at you, expecting you to be spot-on for the duration of your talk. I found myself holding my breath, my throat getting tight, and feeling all jittery. I feel for anyone who is in this situation!
@@LiLi-or2gmi dont care what the reason might be, but it makes me want to skip this one after the first minute. still interesting topic...might endure and watch it .....later.

Why are you proud? Do you write the lecture or have some other vested interest in it?
Some sort of signaling malfunction, perhaps?
Fantastic lecture; she could have gone on for 2 hours and I would have been completely fine with it. This is one of my favorite topics in science.
Pandemic..?
People in sept 2019 : huh
People now : cricket sounds*

Man, I wish this was longer, great lecture.

Great job Ms. Staples!! Very interesting.
really enjoyable and informative talk ,i learned a lot of new stuff about the radiation belts
Existing subject, great lecture and a even as great presentation.
Brilliant talk! I would have liked more around your own phd and what the future research will do, maybe next time if more than 30 min!
Thank You Frances Staples and RI
very interesting, especially the explanation of the belts' different formations
"Comrades, I've been told it's the equivalent of a chest x-ray"

She's radiant !
Amazing lecture Francis!! So impressed! :)
Thank you I was aware of the Van Allan Belts but not the mechanism that traps particles within them. Great talk and informative
1:17 - 400,000 km/s ?????? 8-O
Is this right? 300,000 km/s (more precisely 299,792.458 km/s = 299,792,458 m/s) is the correct value, right ?
Thank you Ri and Frances for the efforts.
This was really interesting.
And to the haters, she did very well.
You go and try to explain things in front of an audience. Sigh.
Very fascinating stuff. Looks like the formation of a sprite at 20:20 in the upper atmosphere. Had no idea how that happened. Mad fer it.

Think of the disruption caused by the Icelandic volcano a few year back

Great lecture
Good talk. I learned something, thanks
RI can you add links to relevant reasearch pages and papers in the descriptions of your fantasic lectures please! I want learn more!
Brilliant and charming both. Thank you.
Excellent presentation
l recommended a professional broker to you guys sometime ago, can I get person who invested with her
comment below
let's gooooo
who made profits for you, am really looking for a pro who can manage my account and make me huge profits
hey wes,
l did invested with her i made huge profits
thanks for recommending her
wow I'm glad I did withdrew my first profit two days ago now I have another ongoing trade with her
I saw that recommendations but I did not bother chatting her up 🤦🤦🤦
who is this professional broker and how would I be able to get in contact with her
excellent talk very interesting
well presented, you are an expert and I've learned something more today. I guess 3D modelling of the radiation flow is too complex, isn't it?
I didnt know about the Astron device. Quite interesting.
So this talk is saying we need production of electronics such as the 1st Evil Empire developed after the second? Not because it was the best but because it was durable?
Great talk, thanks.

That quote will never ever get old :D

The chart was right at 2:32! It was pandemic!
Carrington event, magnetosphere weakening?
another ambassador for the electric universe
_proper cool_
Correction, the US did not send the first satellite into space
Loved the lecture though 👍
Some kind of potato, iirc
The aurora is the conduit through which lightning comes, believe it or not!
I love a woman of science :)
The universe sounds like a record from Jean Michel Jarre, or maybe it is the other way around ;-)
Who? 😲 🤣
Please, subtitles in Spanish 👍👍👍

Did nobody actually tell her how big the Sun ☀ actually is?! 😲 😂 🤣
Nuclear. Just adding a subtitle for each mention of nucular
I know what nuclear means, but “nu-cu-lar” is a new word for me.
"The Cuisine of Italy". Talks about pizza.
She constantly sounds out of breath
Nervous......as would be most great scientist in similar situations. They tend to be introverted people.

Yeah that is what I thought first.. maybe the microphone is to close to her mouth.

I love her voice. Maybe she’s just a bit nervous
Sorry, Annoying to me
If the great men of the past could see what TRI has become they would be so ashamed.
Care to elaborate? I'm not all the way through yet but so far it sounds like a pure science talk.
@@toobnoobify You wouldn't understand. TRI found it all, they conquered the world for it, and now they give it away, they will come back for what they own.
Unwatchable.
Apparently a ‘lecture’ on cutting 1940’s edge “New Cyoo Lar” science. smh!!!!!
Fail Ri, FAIL!!!!!!!!!!
It was a science history class as described, I don't really see how it failed.
They had far less understanding of radiation in space back in the 40's. In fact, it wasn't until they started launching satellites in the late 50's that they had any idea of how much radiation (and what kinds) were out there.
What a happy person you must be mackinnon, posting your spiteful and mean spirited comments on here...
