- In her final Gresham Lecture, Professor Crawford talks about where the next big breakthrough will come from: www.gresham.ac....
For each exciting advance or discovery that takes place in Astronomy, other just as important questions either arise or remain unanswered. In my last Gresham lecture I shall review what the near future might bring - the exciting space missions, satellites and telescopes - and the fundamental scientific challenges they are designed to tackle.
The transcript and downloadable versions of the lecture are available from the Gresham College website: www.gresham.ac....
Gresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters. There are currently over 2,500 lectures free to access. We believe that everyone should have the opportunity to learn from some of the greatest minds. To support Gresham's mission, please consider making a donation: gresham.ac.uk/...
I have never seen or heard a better speaker. A thousand thanks for the many informative and excellent lectures you have given, and i am sad to hear this is the last one.
Nothrazim If you think Prof. Crawford is a good speaker, you should check the lectures by Professor Ian Morrison. Compared to Carolyn he's a god. He explains everything plain and simple while passing to you loads of information, where Prof. Crawford hops from one info to another.. springs back and so forth.
I'm not saying Prof. Crawford is not a good speaker, i really liked her lectures.
But Professer Ian Morrison is/was by far better :)
(in the end, it's just my subjective opinion)
I want more! Please return, Professor!
+Ronald de Rooij Hi,
We recently had a lecture and panel discussion that included Professor Crawford and the Astronomer Royal, Lord Rees. You can find them here:

+GreshamCollege Will she do another series of lectures for us to enjoy and learn from? Her lectures are so enjoyable, clear, informative and excellently paced. She's a gem. :)

Hi,
Its unlikely that she'll do another series, but we'll keep our fingers crossed that she may drop by to give us an update on how the whole 'universe thing' is going.
Regards
GC
I think she should definitely have a podcast/youtube channel
Professor Crawford's lectures are amongst my most favorite videos on this channel. Thanks professor, I've enjoyed every single one of them.
I guess it's time to set up my telescope and hit up some books, eh? ;)

I'm so sad that this is Carolin Crawford's last lecture at Gresham and I do hope that she gets to read the comments here.
Really, Carolin, you are probably the best lecturer I've ever heard. Thank you so much - and I do so hope that you have some way of continuing to teach publicly (including posting on UA-cam) so that we can continue to benefit and be inspired by you.
Heart felt thanks, and best wishes for your future.

I hope to hear her with more direct audio recording. Al Sharpton with a megaphone is easier to understand.
One of the most amazing lecturers I've seen. She's so amazingly saturated in knowledge on her subjects, yet presents them in layman's terms so that anyone can follow along and remained interested.
I keep returning to Carolin's lectures again and again.
I can't help getting a little sad every time I get to this one.
Carolin, wow. Thank you so much. I have never scratched so many excited notes during an astronomy lecture. They are notes to myself about where I want my curiosity to take me over the next years of my life. And it took me 2 years to find this!
Your lectures are my favorite. Sad to see you go.
This was a great lecture by someone who is passionate, smart and deeply immersed in their subject. A great job by Carolin. This is so worth watching.... Hugh
Not that Gresham ever read this, but thanks for all the great uploads and pass on our thanks to Prof. Crawford for all her enlightening lectures. I was once lucky enough to attend one.
I hope she writes a book about the Cosmos.
She is the best orator ever!!
THANK YOU Dr Crawford !! I have enjoyed your series immensely. and it's obvious you put a lot of time and expertise into them. I also appreciate your style which i find both direct and humble, I think you would be a fantastic teacher! - Tim in Kentucky.
Final lecture? Oh, too bad, Carolin is great! She is my favorite lecturer.She is perfect for speaking to laymen such as me.Plus, she has that nifty British accent, which sounds good even when reading the phone book.Good luck, Professor...and thank you!
Thank you Professor Crawford and Gresham College for many informative lectures. I have enjoyed every one. I wish you the greatest luck in your future endeavours.
Thank you so much for delivering all these lectures. It has enlarge my vews on environment and reality. Again thank you.
Thank you professor Crawford for your many lectures on this channel. I find your way of presenting scientific knowledge helps quench my insatiable thirst as well as anyone. Easily rivaling my enjoyment of Carl Sagan, Niel deGrasse Tyson, Brian Greene and others. I hope to see more of you in the future!
excellent science communicator. When will we see you on telly? !
I always look forward to and check for her lectures. Ty
Thanks for all your lectures , Ms Crawford .
I've only discovered them yesterday ( 31 oct '18 ) , and am looking forward to enjoying the ones i haven't seen yet , as well as to revisiting the ones díd see by now .
I'm going to miss hearing more of these lectures, but when your out of topics! Thanks for the lectures prof crawford and of course Gresham college
After viewing a Carolin Crawford presentation, the meager content from Carl Sagan or Niel deGrasse Tyson looks like junk food. The result is proof that attempting more does not mean succeeding less, but the opposite. Praise is not enough to express my gratitude.
I concur. I really hope Carolin Crawford changes her mind and will do another series of lectures on GC that will be posted onto UA-cam.

That would be nice. You may have seen the panel discussion, with her and other former lecturers on astronomy, where Carolin Crawford says she is not going to do more Gresham lectures. But she did say she plans to put more of her professional life toward informing a general audience.
You might not be here listening to this if it weren't Sagan or Tyson. Stepping stones, all necessary for the journey.
1. Putting Sagan in the same league as Tyson is unfair for both of them, but for entirely different reasons. 2. Sagan, quite correctly, wanted to amaze and inspire. This lecture is already for those who know something on the subject and have different expectations. Kaku and Tyson can barely hold Type 1A supernova to Sagan, though he himself would probably disagree...
@@stylz1 Correct. Both of them sought to bring an interest in astronomy and physics to people who knew nothing of them. As you said, because I watched Sagan with awe as a early teen, I can enjoy a lecture like this. There is nothing to be compared here.
I wish Carolin would do these in HD.
Outstanding! thank you professor
Thank you. I watched them all and I have learned plenty and realize there is much more I don't know.
Thank you Carolin!
At 30:45 you sum up the whole truth about everything saying, " It is speculation , it's a thought experiment. We are so far removed from producing any observable thing that can check these theories, check these ideas. And it's quite unlikely to produce observable consequences in the near future ".
Thank you for the great lectures! :)
I am very happy that i made the effort to see her live (at London Museum i think)......she was so awsome, even my dad understood what was going on XD
Re. Lord Kelvin, as appears in Wikipedia: "The statement "There is nothing new to be discovered in physics now. All that remains is more and more precise measurement" has been widely misattributed to Kelvin since the 1980s, either without citation or stating that it was made in an address to the British Association for the Advancement of Science (1900). There is no evidence that Kelvin said this, and the quote is instead a paraphrase of Albert A. Michelson, who in 1894 stated: "… it seems probable that most of the grand underlying principles have been firmly established … An eminent physicist remarked that the future truths of physical science are to be looked for in the sixth place of decimals." Similar statements were given earlier by others, such as Philipp von Jolly. The attribution to Kelvin giving an address in 1900 is presumably a confusion with his "Two clouds" speech, delivered to the Royal Institution in 1900 (see above), and which on the contrary pointed out areas that would subsequently see revolutions."
Scientists seem to have forgotten the difference between the truth and conjecture. Your eye for detail sets a great example for the importance to detail. Appreciated by many, thanks.
Ms. C.C. imparts a wealth of information and understanding. I have watched all of her talks... give us more!!!
If dark matter exists and effects the way stars orbit the galaxy and we're in the galaxy, then why doesn't it ( dark matter ) effect the way the planets orbit the sun in our solar system? Has anyone thought of this? Or am I missing something...?
Billions of neutrinos at relativistic speeds pass through every cubic cm every second , and their impact is zero . Flood the universe with them and their impact will still be close to zero on movement of galaxies , yet their combined contributions to the universe's mass might be considerable .
I'm no big fan of dark matter and even less so of dark energy .
I've made peace with dark matter through the notion that there are so incredibly many neutrinos out there and their numbers increase at an enormous rate every femtosecond as long as there will be stars .
I had forgotten about Jocelyn Bell 16:55.
In 1974 Lowell S. Brown [quantum field theory] got stuck teaching a small honors class in freshman physics at the University of Washington, and he mentioned her discovery.
But each of us that stares at charts of numbers, hoping to see a pattern, can relate.
She was great. Even though most of what she said was familiar, seeing it all laid out took my breath away.
40' - Why use LIGO's line-up for ELISA ?
Why not make use of being out in space and make a 3 dimensional setup , with one central emitter / receiver and *six* perpendicularly placed 'mirror'hubs ?
The technological challenge shouldn't be much harder , and the benifits imo are evident .
wow how did i find this gem?
I like watching Professor Crawford vids with Sunn O))) playing in the background D;
Excellent.
At some point of speculation that leads to observeration and tested theory, you have to accept the available evidence.., probability in possibly of this universe, in principle, provided it's The Principle.
(The speculative Artistic Impression of the Multiverse is fine for crystallography, too restricted for the Holographic probability structure, because it's a 3D+T picture, not a QM-Time image. Combining the "speculations" of Wheeler, Feynman, 't Hooft and Susskind, in principle)
Good talk
That matter and anti-matter were produced with a slight asymmetry (matter>anti-matter) is like Lee Smolin's theory of 'small changes' employing natural selection to explain the evolution of abundant black holes/galaxies (similar to the Darwinian theory of evolutionary changes due to natural selection) that might also explains how 'fine tuning' have been achieved on the cosmological scale.
Again, Caroline's beautiful account of neutrinos (specially the few big ones so far detected) and the asymmetry in particles and anti-particles, may hold the secret of cosmological evolution.-!!!
Where has she ended up?
is it possible for atomic fusion when proto-planets collide? maybe with a requisite large amount of kinetic engery? etc? anyone? or are stars the only way elements can be created past (mostly) iron when they nova?
+ichigeri To get past Iron you need a supernova.
Amazing
here we are in late 2019 and 9 billion dollars later and its still sitting on the ground!.
great!
yesterday a new window was opened...gravity :)
meanwhile.. last week...news came out there might be a planet orbiting earth in-between the size of Neptune and earth a planet 9 ...way out there further away than the Oort cloud and the Kuiperbelt..
Whats wrong with the eather.
6:16 JWST? You optimistic 2015 person, I'm here in 2019 and the thing is still on earth imaging in great detail a hangar wall. I want my exoplanet atmosphere spectroscopic analyses god dammit!!!
We know gravitational waves exist (36.11)... How do you detect a gravitational wave? How do you detect a change in space around you? (37,41)... We've been looking for gravitational waves for five decades and can't say hand on our hearts we've detected some (38.37),,,,,, Wasn't all this astronomy stuff supposed to be all about the data?
xen jeti you spoke too soon
We miss you and your excellent lectures. Your replacement just doesn't fill the bill!
And of course, gravitational waves have already been detected.
is that a real British accent?
Time is not a thing. Its a attribute that weird scientist use. Even in famous equations.
To the question of how to get into astrophysics begin with an IQ of 180+
yeah and the hedron could create a black hole with good old mother earth as its first victim.
she said in every square centimeter that there are a 100 nutrino's passing through.... everything i've ever read says there are billions ....
jedaaa Not exactly a contradiction, is it. Did she say "up to but not more than a hundred?"
I mean, if you're going to be pedantic about something, at least be thorough with it.
+Steve Bergman billions per second per centimeter yeah
+Steve Bergman i got you comment in my email steve but it's not showing up here. however the mathmatics is pretty much Chinese to me. that's why i watch documenteries hehe ;)
Even if we would find thousands of planets who would be exactly like Earth in size and habitat what use would it be? We could use the complete Earth as fuel and we still would not be able the get to the closest one in thousands of years! I tell you what the "use" is, we are spending billions to finance the hobby of a bunch of weirdo's. :-))
She is the best orator ever!!
