Dear Physics Community,

I am sorry to have gone so long without a community message.  Recently, the Academic Continuity Meetings have been more sporadic than usual — which is good as these meetings were born of the crisis last March.  At the same time, much has been happening in other venues.

I’m away this week and will return, with our student announcements, next week.

Above the Fold

Campus operation – Research is going at the 50% occupancy level while the rest of the campus is at about the 5% occupancy level.  The number of positive COVID-19 tests remains very low (Dashboard here).  Testing has ramped up with the opening of the new test center on the Ice Rink in Johnson athletic center.  Access to the campus is possible – please contact Matt, Peter (after next week), or the head of your lab to you would like some time to use your office occasionally. Lots of data here. There have been 34 positive cases since testing started, and MIT Emergency Management and MIT Medical have analyzed where the infections cames from here.

Cool thing – The Alm Lab in Biological Engineering has been analyzing wastewater and can see Sar-COV-2 biomarkers that lead detection by testing by at least five days.  They have set up a pilot in 7 MIT buildings, slides here.  Wastewater sampling is great stuff, and I’ve invited the research lead, Dr. Katya Moniz, to give a lunch talk about their work.

Many discussions about ramping to 100% research and one of the milestones is full compliance, hence this rather unpleasant memo here.

What is going to happen this Spring?  This note just went to academic officers (but not faculty or Department Heads, I’m told).  I have also heard from our students they are being asked about their preferred plans for the spring (i.e. will you be here or there).

Department

• Last week, we had David Elwell from ISO talk about OPT, slides here
• Arup has a new book out on viruses, vaccines, and immunity.
• I’ve spent almost a year working with Tavneet Suri of Sloan on companion reports on how MIT should evolve our gift processes.  They are here.  There will be a Town Hall week after next to hear comments and, I am sure, much more strum und drang after that.
• Information on MIT sponsored tutoring programs for MIT children up to high school.
• Thursday, I hosted a panel, “Should I go to graduate school?” The panel was Wolfgang Ketterle, Richard Fletcher, Yannick Selelim, and Alyssa Rudelis.

Physics

• PRL Cover – Hubbard Model from Martin
• Wha? Department – Nature article on Numpy
• Dark matter – could be primordial black holes, according to Quanta.  I’ve always liked this solution: no new theory is needed.  But, they are hard to find.
• Insight Fellows announcement

Los Endos

I watch “The Social Dilemma” on Netflix – tech CEO’s tell-all about how the tech companies use our data.  Did not learn much new – but if you don’t know, read Soshona Zuboff’s book – but I’ve decided to remove everything Google from my computer. To replace Chrome, I’ve installed Brave as my browser and am using Qwant as my search engine.

Dear Physics Community,

This marks the end of the first week of classes in our new virtualized reality — the summer is now officially behind us. It was long and arduous at times, but hopefully, everyone got a bit of sun. In the midst of everything, a number of organizations in the Department embarked on new initiatives, instituted policy and procedural changes, and began a variety of other efforts to benefit students. This report, by the SPS and PGSC presidents, summarizes the tremendous amount of work done on almost every front this summer to improve the way students move through the Department.

Community outreach opportunity from graduate student Francesco Sciortino

• ​Recently many of us have felt rising pressure to become more active and address social justice, educational access and diversity issues. If you’re on the same boat, now is the time to change gear! In this document, you can find information about 3 opportunities to volunteer with organizations based near MIT: the Cambridge Community Learning Center, the Science Club For Girls and Enroot. Together, these 3 groups support underserved adult learners, girls learning about STEM, and young immigrants in Cambridge. This semester, the majority of these volunteering opportunities will be remote (via Zoom). We are in contact with representatives of each of these organizations and they have told us that they are in huge need of volunteers to address old and new challenges during the next months. If you’re interested, please look through this document and/or email Francesco at sciortino@psfc.mit.edu!

Accessing the Physics Community Calendar: In cooperation with Christina Andujar and myself, an MIT Physics Community Calendar was created for use in Microsoft Outlook.

If you want to your Physics event on the calendar please email Christina Andujar (candujar@mit.edu) and myself (higginsr@mit.edu) with all of the information for the talk itself as well as how to access it (e.g. a zoom link).

When you set up this calendar, you will be able to view and open the individual appointments on this calendar to find the zoom details and eventually the DropBox link will be added with the video if the talk was recorded. Our hope is to have all events posted to this calendar during our time working remotely to help you have a place where the zoom links can live and login information can be accessed.

Dear Physics Community,

Things have been happening fast this week and I’ve gotten behind on the messages.  I will catch up with Anjali and Stella in the next few days, but here are some things from today’s 8 am Academic Continuity Meeting:

• Experiential Learning Opportunities – elo.mit.edu – everyone should look at this.
• New displayed ID requirements – when on campus, need to display your MIT ID, preferably from a lanyard around your neck.  Can pick up lanyards in Lobby 7, residential halls should have lanyards.
• Q-week ends 6 am on Tuesday
• Move-in statistics: 670 undergraduates have arrived, 784 expected.   The normal undergraduate population in MIT housing is 3,200.  1,311 graduate students have arrived out of 1,450.
• Biology, 7.00, on the pandemic,  open to everyone.  (Fauci is listed as a speaker!)
• Rules and Regs. for the start of term
• Pulse survey – Janet Rankin has developed a Pulse Survey for instructors to use in Week 2-3 Guide is here, qualtrics form here.  I mentioned this a lunch yesterday and this will save some time setting up. An early survey can help a lot in improving new online courses.
• Students who have signed up in-person classes for COVIDPass but who do not yet have access to campus will be added to the access list on Saturday, most likely.
• There are now circles around circles various places around campus (Killian Court) for informal gatherings of up to 10 people.

Dashboards

Here is a collection of local university dashboards (and Bates College because my kid goes there).  I’ve love to see someone make a web crawler to produce a consolidated webpage with all the local data.  Please be in touch if you are interested in doing this – I think it would be very popular.

• MIT – just daily testing stats
• NEU– ditto
• Bates – includes isolation statistics
• JHU – NORAD style global view
• COVID calculator – very informative about the risk you and others face in this area.
• Boston University
• BC
• Tufts
• Brandeis

Dear Physics Community,

Summer is ending and our seniors and a few other students will return on Sept. 29.  Testing continues to do well, slides here and classroom scheduling is being finalized. We are ready for what Krishna Rajagopal calls A thoughtfully remote semester.

Some numbers for Fall: Total subjects: 1,377, Virtual subject: 1,181, Hybrid (in-person and virtual) 115, in-person: 81.  On-campus graduate students: 1,900, on-campus seniors: 660, other undergraduates on-campus: 240.  Needed testing rate: 14,000-30,000 per week.

What are other colleges and universities doing?  Here is a breakdown from today’s NYT:

• 6 percent will be online-only

• 27 percent will be primarily online

• 15 percent will be a hybrid of online and in-person

• 20 percent will be primarily in-person

• 2.5 percent will be solely in-person

• 6 percent are doing something else entirely

• 24 percent of schools have still not yet finalized their plans

We are excited to have some of our students coming back: it is a step into a new world and we will begin to learn how to operate so everyone can be back. Here we go…

Dear Physics Community,

I would like to call your attention to Pres. Reif’s letter from yesterday. and focus on two key sentences.  First, from the third paragraph,

“…we are ready to try something more difficult: bringing back a portion of our undergraduates to live on campus.”

This does not sound like much, but it is huge:  In the past week, MIT has stress-tested every aspect of its operations with students back on campus.  Our testing capacity, which averaged 200 tests/day over the summer, was a key test because our testing operation needs to operate at 2,000 tests/day for students to return.  In the past week, MIT Medical ramped testing and yesterday carried out 1,930 tests. You can read the details here.  The average time from test to result is about 20 hours, with all tests being returned within 24 h.

Why is testing so important?  The mean time between infection and the appearance of symptoms for COVID-19 is 5 days, so to catch people early, MIT needs to test twice a week.  MIT will have about 2,800 students (1,900 grads, 900 undergrads) on-campus in two weeks.  Adding about 4,000 faculty and staff (about 30% of normal) coming and going during the week means at least 14,000 tests per week in order to ensure the safety of everyone.  If MIT had not been able to carry out 1,930 tests yesterday, Pres. Reif’s sentence above would have been much different.

The other critical sentence is from the sixth paragraph:

“…while we continue to celebrate and learn from each other’s individuality, we cannot afford individualism. I must take care, for your health; you must take care, for mine.”

What does this mean?  It certainly means wear your mask, wash your hands, keep six feet apart.  It also means being diligent about getting tested if you are coming on campus. The IDSS crew has done a series of studies that show that if 20% of the MIT population “opt-out”, I.e. consistently fail to get tested regularly, COVID-19 will spread at MIT regardless of what the other 80% do.  If you are coming on campus in any capacity, getting your COVID-19 test done is a key part of taking care of yourself and each other.

Everyone should read the guidance for returning students here.  These are the expectations for our students, but versions of this apply to everyone.

Yes, there may be standing in a long line (but that’s getting better).  Or coming at 5 am when they open to avoid lines.  But, it is what we need to do to avoid a repeat of last March when we all had to leave MIT and work remotely.  The next weeks will be a tough adjustment and there will be some positive tests, but if we all stick with it, it will be okay.

Dear Physics Community,

In an effort to improve communication between different parts of the department during these physically-distant times, I have decided to add to my weekly message updates and events from our student governments, the Physics Graduate Student Council (PGSC) and the Society of Physics Students (SPS), as well as a special announcements section, Above the Fold.  On my website, I am also starting to compile a list ​of activities that we as a department are undertaking in addition to our regular duties to help support all of you during these tough times.

Today’s message is longer than usual as we there is much to report.  Also, we are still working out the format and frequency of messages.  Thank you to SPS President Anjali Nambrath and PGSC President Stella Schindler for their reports, and thank you to all of the faculty and staff who have been working tirelessly to support our community.

Physics Department Events

• Departmental Office Hours – 4-5 pm Wednesday
• Community lunch – Thursday 12-1:30 pm

Physics Graduate Student Council

The PGSC is currently working on a number of ideas and projects to improve the graduate student experience, including:

• Crafting and improving opportunities for students to maintain a sense of community while physically apart, via our student Slack workspace, Zoom events, and other ways to stay connected online
• Creating new opportunities for peer-to-peer advising, support, and mentoring
• Informing students about non-academic career opportunities
• Communicating both immediate/urgent as well as longstanding graduate student needs to department leadership and faculty committees that make important decisions
• Ensuring equitable administration of the diagnostic exams (formerly the “written qual”) during the pandemic
• Working towards implementation of the PGSC/PWG social justice recommendations
• Coordinating with other student organizations and coalitions on their goals

This week, student leadership has no tangible output to report, though we have made major headway on important backend work such as research, consultation with stakeholders, as well as planning and deliberation of potential actions we can take in each area.

The PGSC is still looking for volunteers for the following:

• 1-2 volunteers from each division to join a PGSC Task Force to create a graduate student handbook
• A new officer on PGSC: Careers Czar
• Liaison(s) to a national grad student physics anti-racism coalition

To the many students who are struggling out there, know that we are here for you. The Department is working day and night to support you all, and a great many of your peers have effectively dropped their research for the past couple of months to work with them to get it done. I know things may seem confusing or frustrating at times, but please bear with us, and know that we’re trying our best. To the students who have stepped up to help your peers, everyone in the Department is truly grateful. Please feel free to reach out to student leadership at any time with questions, comments, concerns, or if you would like to learn how to get involved.

Society of Physics Students

SPS has been working on a variety of projects this summer:

• the inaugural PRISM conference for undergraduates, happening this Thursday and Friday

• advocating for fewer high-stakes assessments in undergraduate classes for the upcoming fall

• conducting a survey to understand students’ advising needs and communicating that to the department

• starting to act on the SPS equity and inclusion recommendations

• working towards informing students of career opportunities (here’s a starting point)

• partnering with Harvard’s SPS on a series of weekly talks

This week, most of our work has been focused on the upcoming conference. If you’d like to see what ~40 undergraduates have spent their summers working on, please sign up to attend! This will give you access to the Zoom links for the talk sessions and the Slack for access to posters and Q&A.

For undergrads hoping to get more involved with SPS: we will be holding elections for the 2020-21 year early in September. If you have any questions, please email sps-exec@mit.edu, and we can tell you more about the projects we’re working on and the new ideas we’re hoping to start work on in the fall!

• Guidance for instructors on assessments for Fall term related to the APART recommendations

Dear Physics Community,

LOTS of things are happening.  Massachusetts is moving to Phase 3 of the opening while MIT moves to its Phase 2.  For more about MIT in the Fall, Chancellor Barnhardt wrote to the City of Cambridge a letter detailing what will happen in the Fall and Medical Director Cecilia Stuopis made a presentation to the City of Cambridge about MIT’s plans for testing a medical care in the Fall.  There are also updated travel policies for the MIT community.

In the Fall, remote teaching and community building will start.  Here are two new tools that MIT has acquired to help online. Teach remote has training sessions for faculty and new TA’s.  If you are planning to send off-campus students, see this information on remote making about the rules surrounding sending things off-campus.

More Friday…

Stay safe,

Peter

Dear Physics Community,

Fall is beginning to define itself.  This week, we had a lunch discussion with Janet Rankin about low-stakes assignments, slides here, TLL resources here, and my letter to instructors here. On a related theme, I’ve just finished David Kaiser’s book, “Quantum Legacies” and there is an interesting essay, “Training Quantum Mechanics” about the different approaches to teaching the subject.  David kindly sent me a pdf of the essay for our inspiration.

MIT has developed policies for returning students: undergraduates here and graduate students here.  Just in case, faculty/staff concerns can be reported here and student concerns here.

Announcements and opportunities

• Looking for another course?  Biology is offering a course in COVID-19.
• AAPT Virtual Coffee hour on remote learning
• Apply for a MathWorks
• Do you have a grant from the NSF?  New disclosure requirements here

Physics

• I have always wondered how knives get dull cutting tomatoes or a razor get dull shaving.  Now we know MIT News story, Science article.
• Last year, a definition based on the meter and second replaced the kilogram artifact kept at BIPM outside Paris.  I thought we were all set, but no – the radian is becoming an issue. Currently defined as a dimensionless derived quantity, advocates want 1 rad=1 m.m.

Dear Physics Community,

A week of grinding toward Fall.  In the Department, we are working through how to deliver graduate exams.  Today, we had a terrific 90-minute meeting with our Society of Physics Students (Anjali Nambrath, Jeffery Yu, Abby Stein, Sujay Kazi, and Debaditya Pramanik.  Guidance about the ICE rules for our first-year graduate students remains ambiguous, even as we try to figure out how to help them get here. We did finally get clarity on the Visitor Policy for Fall, i.e. don’t.

Physics

• Jobs – I received announcements from AAPT and ORNL.
• More jobs – an alum and friend called me.  He is with Liedos, which helps the federal, state, and local governments in various ways.  he was asking if I knew some close to graduating who would like to spend some time exploring at Liedos on a project involving shock waves, plasmas, and atmospheric physics.  Could be a graduate student, could be undergrad intern.  If this sounds interesting, let me know and I will put you in touch.
• This week, I learned from Tran, that Dave Jackson, who wrote “Classical Electrodynamics” did his Ph.D. at MIT with Vicky Weisskopf, which was news to me.
• Will Oliver has a paper in about creating big atoms to quantum compute with.
• Buzzing gravity in Quanta, Wilczek paper,
