The Story of Spacetime – with Fay Dowker

Fay Dowker tells the story of general relativity and its interactions with Newtonian physics, from Galileo to cutting edge research on the granularity of spacetime.

Fay Dowker is Professor of Theoretical Physics at Imperial College London and works on the problem of quantum gravity. Her research is based on the hypothesis that spacetime is fundamentally granular or atomic, and she has done numerous public lectures.

The idea of mixing the lecture with Meditation was amazing while explaining Gravity was one of the most creative ways to explain something. She is amazing.

Dr Dowker, Thank you for your fascinating lecture. Absolutely riveting stuff. I didn't get every point you were making so I will be taking several goes at seeing how far my understanding can be expanded. Thanks again.

[bobpalka]

Thank you Ms. Dowker for this enlightening lecture. I'm one step closer to understanding GR and gravity then i was before.

[ksbalaji]

That was a beautiful lecture, thank you Dr. Dowker. Would love to hear more from you about the new theories you are working on. Such a clear presentation of the difference between Newton's view of gravity and that of Einstein ! I am a school level Physics teacher in India and am going to use this. Thank you.

Excellent lecture Professor Fowker. Very easy to follow and the material is very relevant and important to the story of spacetime

[JianYZhong]

Thank you, Fay, for such an illuminating lecture on General Relativity, presented so carefully. I even learnt something about meditation!

[muthukumaranl]

Obviously the lecture itself was good...but Its the mention & encouragement of the use of thinking techniques by the professor that i found really useful not just here but in general as a tool to think 'out of the box'...thank you!

Fascinating and engaging talk;made more accessible by the very talented Ms Dowker.

Wait to you hear her thoughts and understanding on "causal set theory!"

Incidentally, the graphics and overheads are very well designed.

[MrLeighman]

Great talk. I actually visualised complicated theory's that previously I had struggled with. Basically: there are no forces between objects only the curvature of space time that they make. The changing of space time by an object acts apon other objects instantaneously. The speed of light remains constant and is independent of space time. Thanks

[brainstormingsharing]

Absolutely well done and definitely keep it up!!! 👍👍👍👍👍

[csam]

Truly the most concise & inspiring speech, thank you

[tomtomski]

Such a calm and clear presentation! I really appreciate it! Great done Prof. Dowker!
I wish I had had my physics lectures with this woman... instead extravert blackboard animal mine lecturer was.

Finally, someone who understands the subject.

[mateopelufo]

Excellent!
Thank you very much.
Carlo Rovelli explanation says that there is no time at all: it´s all a comparison of movement.
I found that notion useful to understand "space time" (taking away time). The movement of anything is affected by the space in where it takes place.

[darkestnile]

Brilliantly explained. I learned a lot. Thanks

[terrywbreedlove]

How does mass actually act on space time and warp it ? I understand that is what is happening but I never hear it explained.

[chipkyle]

Her careful pace and deliberate selection of words allowed her message to "sink in." Her intention was to see that I understood complex ideas rather than impress me with her brilliance. I did learn and at the same time I learned she is brilliant. I will look for more lessons from Fay Dowker. What an honest teacher. Her ego never got in the way of learning. Bravo! We need more of her.

[jansvedman]

One of the best lectures I have seen on the subject. Fay succeed to explain very complicated issues in a simplistic way - and thats very hard and tricky ! Well done.

[VibratoIbanez]

I need a book on Tensor theory with exercises. Can anyone please suggest me the best pdf available online which is free ? (It must have exercises)

[chrisofnottingham]

if some region of spacetime is curved, what is it curved in?ie, what is the reference frame that we consider to be straight?
