Upcoming 2021 Schedule

Jan 20, 2021Quantum Biology (GeorgeG) (video and intro) with discussion
When Quantum Mechanics were first introduced widely, pioneers such as Heisenberg thought that quantum effects should play a role in biology, but for the next 50 years it was sort of forgotten. With today's computing power and instrumentation new insights are being given to explain biological phenomena by invoking quantum effects such as tunneling or entanglement. We will hear 3 experts (MIT, UC Irvine, & U Arizona) discussing the implications of quantum effects in biological entities
yes GeorgeG will supply abstract
Jan 27, 2021Potpourri
Election security, allegations, concerns, why is it so hard to have a closed and secure system? Securing mail-in voting; how states got it to happen. Involve Town clerk or rep to participate? (GeorgeB to follow-up)

(Or, finish earlier topics not completed)
NOT YETneed coordinator or GeorgeB
Feb 3, 2021https://www.pbs.org/newshour/show/the-plastic-problem (1hr video) Plastics having a recycle number on them leads people to think they will be recycled and are perhaps more accepting of then using them. However, many thin plastic containers such as salad boxes or clear takeout containers are not in practice recycled. (John Rudy, Bob Primak, George Burnell) This might be more than one session. Plastic bags biodegradability, manufacture, disposal, recycling.
Bob Beaudoin/Superintendent Environmental Services at Lexington DPW
yesGeorgeB to confirm date with Beaudoin
Feb 10, 2021Polaroid: Recently I learned about a Google talk on the history of Polaroid (Instant:The Story of Polaroid Christopher Bonanos Talks at Google, 2012). It might make an interesting meeting. The talk is about an hour and we could augment it with “actual folks” who worked for Polaroid? With 3-4 people worked there (Peter Albin)
I worked in photographic film product development at Polaroid for 23 years (1976 to 1998). It was there that out of necessity I became in involved in N-dimensional non-linear systems optimization computer tools. I could discuss the approaches that we used and the evolution of the software tools that were internally developed. Many of these tools and graphical visualization aids are now available in the commercial pack Design Expert by StatEase which I used in a final consulting gig at Polaroid in 2003. [Bob Eckert]
yesJohn: need names to include
Feb 17, 2021History relating to Rubber, what used for, how manufactured, WWI, WWII, rubber shortages (George Burnell with Peter, John Rudy)
WWI WWII Japan taking over, fire hoses & rain gear
NOT YETGeorgeB prepare abstract and presentation
Feb 24, 2021(GeorgeG) Mars landing, Perseverance, talk and visuals (if landing goes well, else related space info)yes
Mar 3, 2021Potpourri
(Harry) Getting Streaming Programming Into Your TV (what to do when your TV just isn't smart enough)
Fix-It Shops, Dan Kleppner et al
and more?
Mar 10, 2021Chris Barnett, theory of recycling (GeorgeB to followup)
Chris Barnett, VP waste mgmt
NOT YETGeorgeB to confirm date with Barnett
Mar 17, 2021Why is Venus so bloody hot? The greenhouse effect. (Charlie Holbrow)yes
Mar 24, 2021I. I. Robi, a story of scientific rags-to-riches (Dan Kleppner)yesDan K to supply summary
Mar 31, 2021(GeorgeG to fup) Flying Cars, technology and practical considerations. Woburn company?NOT YETGeorgeG find person to speak and confirm date(date is flexible)
Apr 7, 2021Telephone Switching Before Computers (Ken Pogran)yes
Apr 14, 2021The 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.
Apr 21, 2021Andrea 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
Apr 28, 2021Potpourri
May 5, 2021Space Debris: A Big Problem (Georg Kirchner) When the first satellites were launched some 60 years ago, space was more or less empty. However, the ever increasing launching activities since that now have created a rather crowded environment above our heads: More than 30.000 space debris objects – old / defunct satellites, upper stages of rockets, remaining parts after explosions of collisions etc. – are now orbiting in different altitudes, tracked by radar, laser and passive optical telescopes. The possibility of collisions is already rather high: Collision warning systems create already more than 1000 warnings per day (!) of close encounters between 2 objects – and sometimes this is TOO close – and a collision between two space debris objects, at velocities of 27.000 km/h, creates several 1000 new space debris parts…
Satellite Laser Ranging (SLR) has demonstrated during the last years the capability of tracking such debris objects, helping to determine their accurate orbit, and also their tumbling motions – important features if you want to catch an old upper stage, and remove it from space.

Dr. Georg Kirchner is a group leader at the Space Research Institute, Department of Satellite Geodesy, Austrian Academy of Sciences in Graz, Austria.
May 12, 2021Ivor Morgan is willing to talk about his career in Antarctica, he has photos. It started with him being assigned to a radar station in UK after WWII, then to Antarctica for 2 years. [George Gamota]

May 26, 2021Lex Liby presentation on security by Bruce Schneier https://youtu.be/eVCYX3N-nFQ
June 2, 2021Eli Brookner would like to present to the group “Fun Family Talk on Contributions of Radar to Winning WWII”. Abstract from Eli:
Radar was in its infancy at the start of World War II. The British were using radar effectively along their coastline with a network of antennas on very tall towers to warn of approaching German aircraft, but they needed an invention that would allow radars to be small enough to fit on ships and aircraft. They came up with the cavity magnetron. However they looked to American manufacturing know-how and resources to mass produce this device in a hurry. After turndowns by all the major US firms, a small Boston newcomer, Raytheon Company, came up with a solution and ended up making 85% of all magnetrons used by the allies in the war, and changed the course of the war.
