Mysteries of Modern Physics: Time - Parts 1 and 2

Happy September, NYPGrs!
We're looking forward to seeing you on Friday, September 12th at 6:30pm sharp, if you can! After a short preamble, we'll start with our monthly New Science, always an interesting topic, after which we begin with Parts 1 and 2 of a series of 24 lectures with noted author and scientist, Professor Sean Carroll. It’s Mysteries of Modern Physics: Time. The lectures draw on such ideas as black holes, cosmic inflation, and dark energy and also addresses a question that until recently was considered unanswerable: What happened before the big bang? And while the focus is on physics, Professor Carroll as well examines philosophical views on time, how we perceive and misperceive time, the workings of memory, and serious proposals for time travel.

1. Why Time is a Mystery
   What is a clock” What does it mean to say that “time passes”?Then look at the concept of entropy and how it holds the key to the one-way direction of time in our universe.
2. What Is Time?
   “Presentism” holds that the past and future are not real; only the present moment is real. However the laws of physics appear to support “eternalism’ -the view that all of the moments in the history of the universe are equally real.

After each presentation, it’s our turn to question and discuss..We ask that when you want to speak, plz raise your hand, wait your turn, keep your questions/comments brief and related to the event topic..
AND why not stay on after the regular meeting that ends at 9pm, or as close thereafter, for the virtual No Holds Bar - open til 11+ pm for more informal chat!
Friendly reminder..The Zoom link for this meeting is visible on this event page, to NYPG members ONLY after they RSVP.
Much appreciation goes to our NYPG Team: Linda, for her monthly New Science; to Dan, NYPG Series Moderator, Larry for Short Takes and Aaron who just joined the NYPG Team.. Welcome!! and the rest of the NYPG members for their presentations and support over the years. Thank you all NYPG Members for being there and especially to our NYPG Founder, Mohsen!

About the North York Physics Group (NYPG)

NYPG has been going for about 17 years with over 1,800 members.
Our presentations provide a venue for learning from members and guests academics and scientists. We also have video lectures covering on all aspects of Physics.

We encourage our members to submit presentations or help us find great Physics presenters, whether they be professional academics, post-grads, or just physics enthusiasts.

Within our meetings, each member gets to learn and discuss many aspects of Physics.

The only "formal" qualifications you need to join is a sincere personal desire and enthusiasm for Physics; to keep yourself informed and to courteously share your insights.

Pre-pandemic, after the formal meeting there was the Afterwards..many of us would go a short distance outside to a local pub/restaurant for drinks, snacks, chatting, making new physics oriented friends, or comparing notes with our circle of very scientific friends! For now we hang out at the virtual “No Holds Bar”. Hope you can join us for that! Closing time is 11pm.

BTW: Some members have asked if we will be going back to in person meetings. That would be nice, but, many of our regular attendees are at too much of a distance, or prefer not traveling, so the virtual meetings work well. We are looking into possible hybrid meetings meaning an appropriate free, quiet meeting space where reliable internet service is a must. So far, we haven’t found such a location.

However, the good news is that we've had some great in-person social events for local NYPG members and we will continue to have more In Person-Meetings this year. We’ve had some good ones! There will be three more get-togethers in person this year..Summer, Fall and Winter. Dates TBA!

Mohsen and I would like to thank our Organizing Team: Linda, Dan, Larry and new NYPG Team member, Aaron for their dedicated support of NYPG. Thank you TEAM!
Betty and Mohsen.
