More Ed on Sixty Symbols: youtube.com/playlist?list=PLcUY9vudNKBNtF1y-sneLuy…

Professor copeland is the professor we never had in uni/school but one we always wanted. Great to see him again on 60 symbols
-
Love hearing Brady's questions - it's like having a representative for physics interested amateurs like me - but asking the right key questions. amazing video as ever...
-
My favourite Sixty Symbols professor :)
-
I love how he talked so enthusiastically about those ocelots.
-
Maybe call the initiation of inflation "The Cold Open".
-
This is the best condensed explanation of the inflation model I've heard. Great science communication.
-
Well then. I've been following physics with a rather close layman's interest for about 45 years and this is the first time I've heard that the "hot big bang" came after inflation. Quite a revelation for me and it makes me want to see an episode of Sixty Symbols or Numberphile where someone with the level of knowledge of Dr Copeland is in the middle of this sort of explanation and suddenly stops, gets a blank, mildly puzzled look on his face, says, "I've just thought of something I hadn't before," and goes into some furious computation which results in the solution to a heretofore unsolved physics/mathematics problem, yielding a massive breakthrough in the field. So let's get crackin' guys!
-
Excellent video! 🎉 Many thanks for the kind reference to our work (and our new paper at the end). Ed and Brady rock !! Will think of a new term for the start of inflation in our next paper :-)
-
"you need a better term for the start of inflation" I feel like this is a good point to incorporate the term Horrendous Space Kablooie, introduced by the Watterson-Calvin-Hobbes paper.
-
cannot go wrong with an Professor Copeland video :)
-
WOW!!! That was by far THE Single BEST video this channel has produced in the last 13 years! It was deep, didn't dumb it down, explained it beautifully and filled a bloody big hole in my understanding of cosmology! I can't thank you enough! I can't wait to see what happens to the expansion rate of 1/H as Dark Energy becomes better understood; assuming I'm still here! BIG Thankyou!

My 10 year subscription and I’m so excited to see a rare Ed new video dropped Thanks guy!
-
Ah I love Professor Copeland vids!
-
So if I understand, we now differentiate between some initial singularity and a "hot" big bang ? Wasn't aware of that. Seems everything starts and ends with scalar fields, while everything else is just a consiquence. Can't be easy to present such complex ideas in a simplified way for others to be able to grasp, great team work by Prof. Ed Coperland & Brady.
-
i always love Professor Copeland and his giddy excitement explaining the fine details in the maths leading to the speculative conclusions and especially his recognition of their benefits and flaws. he's always ready to answer Brady's harder questions and can point immediately to the maths for any given wonderment. its stuff like this that inspires me to further pursue astrophysics as a career
-
I love your drive to name things, scientists are spending all their energy on doing science and leaving none left for the creativity of naming things.
-
Great video. He always makes these complex concepts understandable.
-
Professor Copeland, it's always very nice to listen to this gentleman. There ought to be more content with him on youtube.
-
it feels like seeing the professor after 100yrs
