[thejameskan]

love the video really good

[msjessypp]

Very enjoyable thank you

[RyanTheChristian]

I had absolutely no idea Sagan had lectured at the Royal Institute at Christmas. What a pleasure this will be!

[darwiniantheory]

Didn't know he did a RI Lecture :). Fantastic, shall watch all these after boxing day dinner whilst recovering. Happy Christmas all Saganists out there (are we called Saganists?)

[DasIstMeinKampyCouch]

celebrating Carlmas here

[skydome29]

Sounds like Carl had a christmas cold.

[julianken2008]

Thanks a billions and billions

[Horus160181]

Lovely to see these old videos of Carl Sagan. Such a brilliant mind.

[hejjagheterpal]

THX a googolplex for this upload, never seen it before, love the RI christmas lectures!

[TheNewCrankyWorkshop]

@MrAmIAnonymous : Yes, indeed. And if you're not an atheist, exactly the same thing applies.

[kitchenaut]

Thanks for uploading this. Nice to see pre-Cosmos Carl.

It's amazing that far more than 500 planets have been found around other stars, many or a decent fraction of them are larger than all the planets in our Solar System put together and the smallest of sich is just under 1.4 times the mass of the Earth. We are finding planetary system at an amazing pace.

[stuartkwgreen]

Such an Amazing man, i can never tire of listening to him,especially with my awe and fascination of a wonderful mind and person.

[mistermuffin420]

lol hes so nervous. you can tell by his ticks that he has (he has nose ticks [according to his wife])

[Ellesime89]

Saturn and Jupiter actually have over 120 moons if you were to count them all together. Amazing how many we have found since the 70s.

[needabloodyname]

it's beautiful to think that Sagan almost certainly inspired many of the children in that audience into successful careers in physics and other sciences.

[duckingaunt]

Thank you, Mr. Sagan.

[divy34fasho]

I miss you, pluto.

[2plus2is9]

A more refined form of many of the ideas presented in these lectures can be seen in the Cosmos series which was aired not too long after this.

Yet, it was very interesting to see how these ideas were developed and shaped in Carl's mind over the years.

You get the same feeling when you read his books.

[nystagmus]

anybody notice that president obama speaks almost in the same way as carl sagan. pauses at certain moments, etc. could be a complete coincidence but I wonder if he is a sagan fan? anyway, i certainly could be entirely wrong.

[HVAC25000]

Maybe it's just how incredibly intelligent people speak when they want to be understood by others that aren't as intelligent? carl sagan spent his life explaining complex things to dumber people.and always got his point across. Obama obviously did the same because the average american is a moron yet they still voted for him.

[nystagmus]

complex things are broken down to a series of simple things.

[Xellith]

i wouldnt say obama speaks like carl sagan.. since obama doesnt remind me of agent smith in the matrix lol.

[2plus2is9]

The way Sagan spoke reminds me of how grandparents tell bedtime stories to kids. The ebb and flow makes everything much more interesting and keeps the listener involved...unless you over do it.

Obama speaks similarly. Wouldn't it be difficult to sit through his speeches if he was monotone?

[jsb779]

Funny you say that, I noticed the Sagan-ness in Barrack as well.

[nystagmus]

ok i thought i was the only one

[magknight]

Take oratory classes and you'll be amazed how you change your way to speak in public.

[nystagmus]

yes you are right.

[GWR3440]

I hadn't realised Sagan did any of these - I remember going to them 50 years ago and learning about entropy and thermodynamics, A wonderful London tradition.

He gets respect from me for this.

[Demosthenes140]

Thank you so much for uploading these lectures.

I miss Carl Sagan. The human mind and spirit at its very best.  Just one great guy!

[sirkamon]

Thanks for uploading this!

[asrowley]

This man is an absolute legend!

[venompangx]

As Christmas approaches, I wish I there was a good Christmas lecture to attend.

[9Rayvik9]

Hey, thanks for uploading the video. But there is one part in it in which he refers to a planet between saturn and uranus. I know this is not true considering its been decades since the lectures. But do you know what he was possibly referring to?

[venompangx]

If you can tell me which clip and give me the time, maybe.

[SithRage]

@venompangx 2:40 range

[ugoogalee]

@venompangx 2:40 in

[radiofan6872]

@venompangx Sagan mentions it in this clip about 2:50 although it's probably one of Saturn's many moons.

[pioneer101112]

@venompangx Carl was referring to 2060 Chiron, a type of planetoid discovered in 1977 that orbits between Saturn and Uranus. Until it was made into a new class of planetoid, some astronomers seriously considered making it a new main planet.

[LeonhardEuler1]

@venompangx Part 1 1/6 @2:35

[NavixWolven]

@9Rayvik9

He was referring to what we now know Pluto to be. Dwarf planets :) There are many and they are mostly un-named :)

[FrankLoydWright]

@9Rayvik9 i think hes talking about ceres or eris i cant remember which one is between saturn and uranus. in any case they are both classified as dwarf planets[i think]

[harbingerdawn]

@9Rayvik9 He was referring to the centaur 2060 Chiron, recently discovered at the time. Centaurs are the name given to minor objects orbiting the sun outside the Asteroid belt, but inside the Kuiper belt, regardless of their composition (i.e. they can be rocky like asteroids or icy like comets). Chiron was the first discovered.

[18thAngel]

@9Rayvik9

The object we was talking about is most likely Chiron, and object which belongs to a class known as centaurs that orbit between Saturn and Uranus.

[profound13]

@9Rayvik9 I believe he's referring to a body that was eventually classified as a moon.

[evanjdanderson]

@9Rayvik9 2 years later, but, I believe the object he's referring to is 2060 Chiron, a minor planet confirmed in 1977.

[12301231234]

@9Rayvik9 I think he is referring to Chiron (Search Eso.org for Chiron, should be the first PDF, for the original paper on it) which was originally assumed to be a small planet but is now considered a centaur object. I would imagine that it is a captured Kuiper belt object, but that's just my guess.

Thank you for re-posting this playlist! I was ripping my hair out because it was removed for a while!! THANK YOU! RIP CARL SAGAN
