*October 4, 2023*
(Tentative) The art of Space-Time (Anna Barnackna) Gravitational Lens Effect.
(Since the discovery of the first lensed quasars in 1979, this quirky
phenomenon has become central to cosmology, as light rays from distant
galaxies are deflected (a bit) by gravitational effects of both dark matter
and dark energy. DM and DE are the two big mysteries of cosmology – and in
physics for that matter.) Marc Gorenstein *SPECIAL NOTE  -* *Links to many

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 available on 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.

   - We, the Lexington Computer and Technology Group, will meet Wednesday
   at the usual 10AM Eastern Time online, using the Zoom Video Conferencing
   Application, facilitated by Steve Isenberg. (If noted above, we may also be
   at the Lexington Community Center.)

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



To join our online meeting, sometime after 9:45 AM 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).
