Small Bodies of the Solar System - Professor Carolin Crawford

1. Seeing the amount of rocky objects crossing earth's orbit, I am truly worried now after this lecture.... I never thought there would be so many on a possible collision course with us.
2. I have learned more from Professor Carolin Crawford than from any other astronomer. She's a wealth of information and understanding.
3. interesting as always.
4. At 50:41 (or about), there's a graphic with all the dwarf planets. There's a typographical error in the spelling of Haumea's larger moon. It should be spelled Hi'iaka, not Hi'aka. (I don't know how to type the backwards apostrophe, common in the Hawaiian language. I also wonder why Salacia wasn't included. Otherwise, I thought this was fantastic.
5. We didn't then... but we do have "beautiful" pictures of Ceres, a dwarf planet, now. Artists really do need to reign in their "impressions". This is a color photo. http://dawnblog.jpl.nasa.gov/wp-content/uploads/2015/02/CeresBig_LR.jpg
6. She is terrific!
7. This lady is the clearest expositor of astronomical science anywhere around, and she completely eschews substituting childish portrayals for actual attempts to explicate the science. What a wonderful gift to us all!!!
8. "these all objects are orbiting " ... u and me babe .. i dont want your body .. i want u 2 know .. theres a mind - orbiting on other side of this EARTH .. and there are 2 more on south side ...
   its an orgy of minds ... less u poor and have 2 sell glass bottles 2 buy bread
   as i write happy ... u did what i could not avoid .. and point it up vs me
   just - happy minds in the gutter ..
   my thesus
9. we lill go 2 inner sollar system 4 mining 1st ... cause its hot and been coocked 4 us
10. i do think shes a fox ... a lady of mind id like 2 bang ... its not cruel 2 advert your pasion of galaxies and stars and boosoms pointy pointing at star maps
    u want money .. money dont exist .. star maps do ...
    i want big titties in my face ... and star maps
11. i own this world ...
12. let me not poin the question 2 u .. let me point it at Grasham ... if u and all the big heads knew its uneven .. gravity ... try teen try puberty ... geens .. turn on turn of .. puberty at 14 as such at 60y
13. i think she likes me thats why my comments/questions were blocked ...
    gresham ... ints nice 2 know some of our puny humans get axess 2 knowladge
    at a point of a knife .. I OWN THIS WORLD :)
    have 2 pretend im just a
    3.4 billion nukes on the dark side of the moon ... when u lauch u need a kick
    ... like u never wanted 2 own a world .. its fun u poor as dirt but u can say
    I OWN THIS WORLD ..
14. 2 RonJohn63 - its allot as in tons and tons ... gold is worthless unless industry say it is
    u want an ouce of gold or a burger .... cant eat metal
    who ... who you gona sell it 2? .. u go 2 jail cause its untraceble
15. As usual, the professor easily tops all the other presentations on the topic she selects. All are both more comprehensive and more explanatory, which is not just amazing, but seemingly irreconcilable. I suppose that comes down to how to organize thinking on a topic. I am currently finding these small objects more interesting than the well known big ones, because they are more mysterious.
    
     It appears that Jupiter is the organizer of the rest of the solar system. Coincidentally, or not, Jupiter is the master god in the ancient Roman religion.
    
     Astronomy tends not to get any deeper into physics than strictly required, so I got the idea that planets were round because gravity tended to assemble objects statistically equally from all directions. This is discredited by smaller objects not being very round, although they do seem to be rounded off. What happens on planets like earth is that the weight of the outer 20 miles or so creates pressure on the matter below which is higher than the strength of the materials, after which the matter acts like an immensely viscous fluid. So below some depth the matter is like a droplet that is pulled into a sphere by gravity. If there are different materials, they stratify into layers. At less depth, the matter can be very irregular, until the height of the irregularity crushes the base or makes it flow. On Earth, because of the presence of bound water which weakens rock, this dictates that the height of mountains should not be more than about 5 miles. (Venus has far higher mountains.)
16. This was great! I've become a huge fan of this series. I've gone back and watched the rest. Thank you so much for this absolutely excellent series.
17. Thank you Carolin for your knowledge, I wish I could see your last lecture in London next month.
18. Glad to see my asteroid discovery movie being used to educate people.
19. talking about mining - with all these space missions its starting 2 look like the earth/us are getting mined and the precious minerals/metals are getting sent out into universe
    ... if i had an alien space ship id just park out there and go wow look at this there spiting out gold platinum paladium plutonium lead solar pannels ... we dont even have 2 land
    humans - they so nice :)
20. Was impressed, learned, and enjoyed. Thanks
