(NOTE: Repeated Reminder with no content change.)




*Apr 7, 2021 *



*Venus and greenhouse — and Mars and Earth* (Charles Holbrow)
*What I learned from my Climate Science Study Group* (Jerry Slate, Carl
Lazarus, Harry Forsdick, Mike Alexander)



*SPECIAL NOTE - **Links to many of our previous sessions are available
online at http://lctg.toku.us/ <http://lctg.toku.us/>, thanks to the
diligence of Steve Isenberg. This includes the Mars Landing presentation of
February 24.*



We, the Lexington Computer and Technology Group, meet at the usual 10AM
Wednesday time, BUT ONLINE, using the Zoom Video Conferencing Application,
facilitated by Steve Isenberg.

There is an instruction page at https://toku.us/zoomish but note that the
URL and phone number shown are examples.



Sometime after 9:45AM on Wednesday, choose one of the following options:

   - If you have the Zoom application installed, start it and join meeting
   with ID 972 6146 0830
   - From your browser, go to: https://zoom.us/j/97261460830
   - From your smartphone, tap this: +16468769923,,97261460830
   - From a “dumb” telephone, call 1 646 876 9923 and enter meeting ID: 972
   6146 0830

Once the connection is established, you may need to locate and use the
on-screen controls that turn on the sound and the video. You should be able
to see and hear others and they should be able to see and hear you, if you
have a camera and microphone (each of which you can unmute selectively).



If this email wasn't addressed to you and you would like to join the group,
or if you have a friend or colleague who might also be interested in
joining, it's easy.  Ask them to go to the group's wiki page at
http://LCTG.toku.us and follow the simple instructions under "Join the
Email List".  By being a member of the group you'll get reminders of
upcoming meetings and infrequent related messages. No advertising.  The
list is tightly managed.

Membership is free and given that all meetings are using Zoom you only need
to be connected to the Internet to join.  It's ok to join from anywhere you
can get a decent Internet connection, even if you're in orbit around Earth
or on another planet or a moon (if you're connecting from somewhere not on
Earth, we'd like to chat).

*Below are our plans for Upcoming Meetings. For more schedule information,
please refer to https://wiki.toku.us/doku.php?id=lctg_speaker_schedule
<https://wiki.toku.us/doku.php?id=lctg_speaker_schedule>  We will continue
to have an online presentation (almost) every Wednesday until it is prudent
for us to resume meeting in person.*

*The Apollo Mission* Presented by Fred Martin, ScD.; Dr. Martin served as
the Apollo Software Project Manager while at the MIT Instrumentation
Laboratory (now Draper Lab) and then pursued an industrial career in
software analysis and management.
History will surely record the voyage to the moon as being the greatest
adventure of the 20th century. We will first examine our fascination with
our closest neighbor and early speculation of travel through the writings
of Jules Verne. We will discuss the principles of how a rocket works, gain
an understanding of JFK’s decision and confidence to place a man on the
Moon, and experience the Apollo Moon Project “first hand:” its methods,
triumphs and surprises. Our resources will include Dr. Martin’s experiences
within the Apollo Program and videos of the exciting minute-by-minute
landing on the Moon’s surface.

* Black Holes *Andrea Ghez; won Nobel Physics for black holes, Brian Green
video has interview with her. JohnR has videos with Ghez (and will
investigate applicability for LCTG)
https://www.youtube.com/watch?v=YcPPGVigvZk This is an excellent
description by Andrea Ghez (2020 Nobel Prize winner in Physics). It is 50
minutes long and is an excellent example of women in science. I think it is
better than her interview with Brian Greene. It was given at the World
Science Festival which is run by Greene
