Online Meteorite Lectures

Online Meteorite Lectures

Incoming: Learning to love the meteorite
Geological Society of London lecture
Lecture by Dr Ted Nield given at the Geological Society
on 19 December 2012 as part of the 2012 Shell London
Lecture series.
https://www.youtube.com/watch?v=SuYKYRHMq4U

"New research is suggesting that 470 million years ago, a
stupendous collision in the Asteroid Belt (whose debris is
still falling, to this very day) bombarded the Earth with
meteorites of all sizes. A revolutionary idea is emerging
that the resulting ecological disturbance may have been
responsible not only for massive worldwide submarine
landslides, but for the single greatest increase in biological
diversity since the origin of complex life -- the hitherto
unexplained Great Ordovician Biodiversity Event."

Lecture 2

Geology in Space: Meteorites and Cosmic Dust
Geological Society of London
Published on Aug 7, 2014
By Matt Genge, a planetary scientist and geologist
from Imperial College London
https://www.youtube.com/watch?v=OMTl5fY4QW4

"Geology no longer is the study of the Earth. Rocks
are found throughout the universe on other planets,
asteroids and comets and as debris ranging in size
down to the tiniest pieces of stardust."

Lecture 3

The meaning of meteorites
Royal Astronomical Society Lecture
Published on March 24, 2015
by Dr Ted Nield, Geoscientist Magazine
Royal Astronomical Society public lecture, 10 February 2015
https://www.youtube.com/watch?v=6lgd_bJELtM

"Ted Nield surveys the ways impacts have influenced life
on Earth, and suggests that, as with ideas, meteorites have
'timeliness', because the effect of any single cause, in
human as in Earth history, is controlled largely by the
context in which it occurs."

The below lecture has nothing to do with meteorites.
It is just fun fossil hunting.

I wrote:

“or as stated by Dr. Ralph B. Peck:
“If you can’t reduce a difficult engineering problem to
just one 8 1⁄2 x 11-inch sheet of paper, you will probably
never understand it."

J Bryan Krämer replied:

“Number two reminds me of the Elevator talk
principal: if you cannot condense a difficult idea
down to a elevator talk then you don't understand
it. Author was some big name Physicist. Apparently
not Einstein or Fermi. Anyway I'd like to see a
mathematician do that for the Riemann Problem, I
read a whole book on it and still don't get what
it's about.”

Even the best of matheticians have the same problem
with understanding what their fellow matheticians write.

Great YouTube Lecture Series On Engineering Geology

Great YouTube Lecture Series On Engineering Geology

There are some great Youtube lectures about engineering
geology by Dr. David Rogers, University Missouri at
https://www.youtube.com/channel/UC8rEEIEMhazZBvsKB_e7xzg .

Although long, the nice thing about these lectures is
that person can view them at their own pace and time.
Also, Dr. Rogers occasionally talks about how to survive
as an consulting engineering geologist and the trials and
tribulations of field work during his lectures.

Another web page contains links to the Powerpoint files of
the lectures at
http://web.mst.edu/~rogersda/umrcourses/ge341/ .

For example, are some very nice examples of spheroidal
weathering and jointing in the powerpoint at
http://web.mst.edu/~rogersda/umrcourses/ge341/online_lectures/weathering/Weathering-pt4.ppt
.

They go with the lecture at
