I'm really looking forward to his hosting the reboot of Cosmos next year.  Couldn't imagine a better man for the job.  His ability to explain things in layman's terms without coming off as condescending is amazing.

I'm looking forward to it too.  I just re-watched Cosmos not that long ago (it was on Netflix streaming), and it holds up well.

Didn't realize that was on Netflix streaming, may have to get billions and billions of weed and rewatch it myself.  I just hope Tyson doesn't try to "be" Sagan, because he is not.  I wouldn't say one is better than the other, but he's got his own thing going and I hope he sticks to that.

This.

If I had one "complaint" against the original series, is that it's paced kind of slowly.  I don't mind, not really, but some may.  I don't think that will be a problem with NDT, though, because his style is different.  Carl was cool but aloof.  Neil is more "science guy you'd drink a beer with".

The pacing was fine. It was similar to James Burke's "Connections" series -- the stories unfold as a novel through history and allow the audience to absorb the content.

I'm really concerned about the hyperspeed of modern TV and movies -- everything is at ADHD video game speed. There's no time to let thinks sink in and establish. No wonder our kids are plagued with ADD and medicated.

Fred Rogers purposefully paced his shows so kids could understand and regulate their responses instead of being bombarded with flashy content.

Dear God no. Have you ever watched a documentary narrated by Tyson? Let him talk as himself yes, but get a professional for narration.

I don't think he cracked a joke the entire time, and it was interesting and informative. Maybe him on Cosmos won't be so bad after all.

Apples and oranges.

Connections was about how human history was intertwined, instead of a series of isolated events.

Cosmos, while it had a lot of history in it, was about, well, the Cosmos.

NDT is the Kim Kardashian of science. He's famous for being famous (in these sort of circles). Otherwise, he has no more appreciable talent than the next egghead.

un4gvn666: I must be a moron, because I didn't understand his answer much at all.


It's him.  Heard him for the first time on the Joe Rogan Experience.  I can't understand the hype.  He's great at answering questions with questions, and deflecting anyone who points out he's full of shiat.  Great self-promoter though.

I don't know. I would kind of like to see Neil DeGrasse Tyson get stoned to the bejeezus-belt and start talking about stars and stuff.

Actually, I've seen him live and I think he's pretty goddamn condescending, but maybe I caught him on a bad night.

I'll grant that he's both entertaining and informative while being condescending, which is most of what matters.

So it's going to be on Fox?  Maybe right after Cosmos they'll run a "Searching for Noah's Ark" just to balance things out.

FTA:
"By the way," he said, "once you put the vacuum in it, and then you bring it back to Earth, what will happen is the inner surface of the glass and presumably a metal lid, will outgas into that volume. There are gases dissolved in the surfaces of all solid objects and it just stays there. It's molecules that are just stuck in the jagged-y surface of every solid object."
"If you would now evacuate the center of that jar," he continued, "it dislodges those gas molecules. And so, then, it'll put some kind of gas pressure back in."
He explained that in trying to create a perfect vacuum, scientists must empty a container and then heat the sides, releasing the gases trapped in the solid surfaces. "Then you vacuum it out again."
To bring a container of vacuum back to Earth, he said, you'd need a container with such smooth interior sides that they trap no gases. Much, much smoother than glass, he said.

So I'm not a super genius, but wouldn't it be easier to just put a hot jar out into space and let it outgas before putting the lid back on?

Kibbler: Personally I can't stand the guy.  He's more of a celebrity than a scientist.


A bit harsh, but yeah.  Carl Sagan was a scientific giant before he ever appeared on TV.  The national academy of sciences embarrassed themselves because they were being obvious dicks and not voting Sagan in, his scientific accomplishments were that solid.  He wrote books that did not pander, and explained things in depth.  Even as a distinguished senior professor, he volunteered to teach freshmen seminars.  In Cosmos, the simplest of his books and written for a broad audience, the pacing is slow precisely to allow people to contemplate the enormity of what he was talking about.  Wait, did he say there are hundreds of billyuns of stars in the galaxy?  And hundreds of billyuns of galaxies in the universe??  Holy fark!

Tyson is another talking head OK-scientist but big personality inserted into the latest generation of slice-n-dice edited infotainment crap.  On a personal level, Tyson's much more of a renaissance man than Sagan.  Sagan was never great at any sport or music or other activity and didn't do much outside of science, and his forays into stuff outside of astrophysics were lame, but he was unarguably a great astrophysicist.  Tyson just ain't.  At least he isn't routinely full of shiat like Michio Kaku, I'll give him that.

buckler: I always saw him as the natural successor of Sagan, who was one of his professors.


No.  Sagan apparently did try to recruit him as an undergrad to Cornell, because Tyson's admission letter had been passed on to Sagan, but Tyson chose Harvard and then UT-Austin for grad school.

Actually, if it's built like most jars, having the vacuum on the inside of the jar will make the lid stay on even tighter.

But eventually, yeah, you'd probably get some leakage into the jar.

You know, it strikes me that NDT is more, well, colloquial and jovial than Carl was.  That can't hurt when you are trying to popularize science.
