Non-Euclidean Geometry [Topics in the History of Mathematics]

- Another Open University oldie. This one's a bit more hxc (and considerably older - the 1970s public were apparently considered far smarter than we are today!), but it's mostly easy enough to grasp if you put your mind to it.
Non-Euclidean Geometry is relevant for the Riemann curvature of space-time in General Relativity and all that. It's also interesting to watch logic (or a bearded professor) decimate what was once considered to be a fundamental truth of mathematics and reality, if you're into that sort of thing. (maybe that's a bit over-dramatic).
I used to creep down stairs in the early hours of the morning in the 1980's to watch Open University. Happy days!
+Mike Fuller I never understood a word of it! I just liked it and admired how clever the lecturers were! I wished to be as clever!
+Mike Fuller how cute :)
what with cock in hand
+Vladi Nekoloff (vengerer)
Thank You, Vladi!
It is nice to come across a nice person!
+Mike Fuller Me too I used to watch it as a child - goodness knows I couldn't understand it
I used to watch them every weekend as a kid, because I got up early and there was no kid's TV on until later back then. If you wanted to watch TV early, only this was ever on lol.
We need more intellectually stimulating television programmes like this, and less X Factor.
Absolutely - TV has gone downhill since those days - chasing the lowest common denominator - sad really ...
Can't be done.
The initial audience would require skills for every new TV show the likelihood that the whole audience can watch and comprehend is very low.
Someone needs to collate all stimulating programs into a youtube guide.
this is fantastic! i love this timeless instructional programs
I actually remember watching this - it would have been one of its last TV showings in the mid 2000s (maybe this showing?) when I was a sleep-deprived teenager. Didn't quite get all of it but interesting to watch!
i think i must've taped this slightly earlier than that - I remember watching it with my housemates 2000/2001/2002?
Pretty impressive that these old shows had such longevity anyway
I miss open university programs on tv on in the early morning
21:31 Oh, Jeremy!
mind blown at 12:21
Beautifully told. Thus just triggers my curiosity.
Fantastic video. Helped me get the basics
Anyone else procrastinating math homework to watch this?
Brilliant videography! The shirt that changed.. The camera dollies and the 3D models. Wow.
How I can get the script of this lecture or video?
i love when he's making a particularly noteworthy point and his voice cracks.
Thanks for uploading ... Do you have anymore videos in the series?
Afraid not, I taped over a lot of subjects after I later studied them so mostly history and nature docs left.
Sorry to hear that. Anyway - check this out and tell me what you think ...

Chopped4Skin Sorry, just saw this it was marked as spam!
Jeremy Gray is still at the OU :)
Thank you for the upload! :)
0:15 either Jethro Tull or Mick Fleetwood teaching math.
Left school with no exams ,didn't like the style of teaching , used to watch these to see what I was missing got married and worked all hours god sent bang went watching them . Much later on I was recovering from severe ear infection and surgery read a book forget title in which it claimed that time is relative and gravity is a fictitious force. This was contrary to what I learned in school,I liked science there, got into special relativity and tried to understand general relativity still trying geometry on a sphere is the key but alas the mathematics is still beyond me. Learnt a lot about Einstein the man though .
It seems that men wore non-Euclidean clothes in the 1970's....
Yes Joseph I remember the 70s rather stylish.
Oh man, I remember watching this when it was on! Up way too late.
That gives me the fuckin' nostalgia horn
Well, that was clear enough. Lolol.
The 5th postulate *is* intuitively obvious.
Ah yes, curved space. *straightens monocle*
Creepy good..
"The Sum of the Angles" by Concretism brought me here.
That parallel postulate looks obvious to me.
Be honest how many of us had heard of this topic before now?
I watched this as part of my degree course!
i think euclid refered only to a straignt line in his parallel postulate. . a line drawn on a globe is not straight so the postulate do not apply.
we live in a non euclidean space
Good old bbc
i'm procrastinating going to bed ;)
looks like a non eucledian beard :D
It's actually infinitely large at the tip.
This is dumb. Euclid's postulates are valid IN Euclidean space.
Gee, why doesn't diesel work in a gasoline engine?
blew my mind
Geometry hmm interesting.
This guy must have got some serious poontang
rkent06 ill bet he can't swear online what the fuck
