"The Cloud" - Great Ted Talk About Being A Scientist

"The Cloud" - Great Ted Talk About Being A Scientist

This is a great Ted Talk that speaks to a part
of conducting science that scientists do not
normally talk about to the lay public

Uri Alon, 2013, Why truly innovative science
demands a leap into the unknown
TEDGlobal 2013, Film 2013.
https://www.ted.com/talks/uri_alon_why_truly_innovative_science_demands_a_leap_into_the_unknown?language=en

There is a web page with materials that give
advice about being a scientist. It is:

Materials for Naturing Young Scientists,
Uri Alon Lab, at:
http://wws.weizmann.ac.il/mcb/UriAlon/index.php?q=materials-nurturing-scientists

It has papers about choosing research topics,
how not to a seminar, and so forth.

For an unrelated story about misadventures
in the peer-review process, go see;

Free Geologic Time Scale Creator

Free Geologic Time Scale Creator

TimeScale Creator
by Katelyn Verner and Rebecca Bobick,Purdue University

https://engineering.purdue.edu/Stratigraphy/tscreator/index/index.php

According to the web page:

“TimeScale Creator, a free JAVA package, enables
you to explore and create charts of any portion of
the geologic time scale from an extensive suite of
global and regional events in Earth History. The
internal database suite encompasses over 20,000
biologic, geomagnetic, sea-level, stable isotope,
and other events – details are given on the
BUILT-IN DATA page. All ages in TSCreator
version 5.4 are currently standardized to Geologic
Time Scale 2004, and to the Concise Geologic
Time Scale, 2008 compilation. The age model
for TSCreator version 6.3 is from "The Geologic
Time Scale 2012" by F.M. Gradstein, J.G. Ogg,
M.D. Schmitz and G.M. Ogg (Elsevier, 2012).”

Webinars about the TimeScale Creator and other
uses of computers in paleontology and geology
can bed found in "C4P Webinars" at

Lecture About Organic Rich Mudstones (Including Their Paleontology)

Lecture About Organic Rich Mudstones (Including Their Paleontology)

There is a wonderful, although long, lecture about
organic rich mudstones that can be viewed online.
It is “Organic Rich Mudstones-Questions” at:
https://www.youtube.com/watch?v=9GVdJAmf7FU

Although it aimed toward oil and gas exploration,
he does discuss the paleontology and taphonomy
of organic rich mudstone (“back shales”) in some
detail. What he has to say about the paleontology and
taphonomy of these rocks is quite interesting.

This lecture is just one of number of lectures that
the Houston Geological Society has online at
http://www.hgs.org/multimedia_Education

I also found interesting is “The Largest Volcano in
the World-Mid Pacific Ocean” by William Sager at:
