concentration signup

by Morin, David

This email is for the sophomores among you who are interested in signing up for the Physics or Chem/Phys concentrations. The deadline to declare a concentration is Thursday, November 17, but please don't wait until the last minute! A list of possible 20-minute meeting times with me in Lyman 238, starting this coming Wednesday 10/5, is located at the following link (I'll gradually add more times in later weeks). Write your name in a time slot (and make a note of it, so you don’t forget). https://docs.google.com/spreadsheets/d/1GmSKP-i5GyUXdhrHhT9dTL-8r2Bonbzu-PR… We'll use the meeting to go over your plan of study, talk about the concentration, and take care of a few other logistics. It's a fairly harmless procedure. But a few things to do beforehand are: 1) Fill out the Registrar's declaration form. Instructions are here: https://harvard.service-now.com/ithelp?id=kb_article&sys_id=529e5ecadb6f4f0… 2) Look at the concentration requirements listed in the Fields of Concentration: https://handbook.college.harvard.edu/files/collegehandbook/files/fields_fin… and think about what courses you want to take that will satisfy the requirements. (Clickable index near the beginning. Chem/Phys is on page 42, Physics is on page 185.) 3) Make a plan of study. I recommend using Excel (or something similar) to list out the 4 courses in each of your 8 semesters. When making a rough schedule of your remaining 5 semesters, you of course don't need to stick to it exactly, but it's good to have an existence proof of a plan that works. 4) Think about whom you want as your concentration advisor. Everyone has Prof. Georgi and me automatically, and we also pair you up with another faculty member. Make a list of a few possibilities, in case your first choice is overbooked. You can peruse the list of Physics faculty at: https://www.physics.harvard.edu/people/faculty PLEASE HAVE **THREE** NAMES IN MIND when we meet. Note: there is no best way of picking names. Maybe a prof is doing research you find interesting, or you were in a class they taught (definitely not necessary), or a friend spoke highly of them, etc. You don’t need to have met the prof before. 5) Fill out this google form: https://forms.gle/tWstcghbxy2tf5e39<https://urldefense.proofpoint.com/v2/url?u=https-3A__forms.gle_tWstcghbxy2t…> If you have any questions beforehand, stop by my office hours: https://scholar.harvard.edu/david-morin/office-hours or Prof. Georgi's: https://sites.harvard.edu/hgeorgi/ These hours are set up at the beginning of each week, but check them during the week for any changes that may come up. Frequently asked questions are located at: https://www.physics.harvard.edu/undergrad/faqs-concentrators We look forward to having you officially join the department! DJM

Academic Advising Report

by Morin, David

Concerning the Academic Advising Report in my.harvard, the report can be misleading, so please ignore it, at least as far as the Physics and Chem/Phys concentration requirements go. It might say that some requirements aren’t satisfied when in fact they are. And conversely it might say that some requirements are satisfied when they aren’t. (However, the Gen Ed and Distribution parts of the report are probably accurate, so do pay attention to those.) The requirements that you should be looking at are the official requirements listed in the Fields of Concentration: https://handbook.college.harvard.edu/files/collegehandbook/files/harvard_co… (Click on the index at the beginning to go to the Physics or Chem/Phys pages.) If you want to submit an exception to the Advising Report to make it more accurately reflect your requirement status, feel free to do so. But again, it doesn’t matter. If you do submit an exception, please include a short explanation in the description box.

Phys 191

by Morin, David

For those of you who will be taking Phys 191 this year, you are strongly encouraged to take it now in the fall. The enrollment in the spring is always much higher, so if you take it now in the fall you’ll get far more professor time, and things will be much calmer.

Phys, Chem/Phys Advising

by Morin, David

I hope everyone has had an enjoyable summer. The new semester is fast approaching, so here we go... This email is relevant to the Physics and Chem/Phys concentrators among you. It's a long email, but please pay special attention to the "YOUR TASK" item below. THE SHORT VERSION: Email your concentration advisor and set up a zoom meeting sometime between Mon 8/16 and Wed 8/25 (Thurs 8/26 is the course registration deadline). Your advisor will lift the hold on your crimson cart (sometimes called “study card”). More info on the various dates can be found here: https://college.harvard.edu/guides/course-preview-period THE LONG VERSION: (1) A picture of your Individual Concentrator Advisor should show up in your my.harvard list of advisors. If it doesn't, or if there are any issues (you want to change advisors, etc.), please let me know right away. (However, I’ll be away from 8/14 to 8/21.) (2) All of you automatically have Prof. Georgi (Head Tutor) and me (Co-Head Tutor) as academic advisors. You can talk with us about anything at any time, ranging from course selection, to future plans, to lab work, to concentration requirements. Our office hours are posted at: www.people.fas.harvard.edu/~hgeorgi<http://www.people.fas.harvard.edu/~hgeorgi> and https://scholar.harvard.edu/david-morin/office-hours, zoom link: https://harvard.zoom.us/j/95258793192?pwd=cEViNis1d1ozNDk3MmdpWjRyOVY1QT09<https://urldefense.proofpoint.com/v2/url?u=https-3A__harvard.zoom.us_j_9525…> We encourage you to drop by zoom, but email also works. (3) In addition, we give all of you another faculty advisor. The purpose of this Individual Concentration Advisor is to act as a mentor, and to help you down the Physics or Chem/Phys path. However, concerning concentration requirements, Prof. Georgi and I have seen all the ins and outs and variations on these, so we encourage you to save such questions for us. In short, when talking with your faculty advisor, you can pretend that there are no course numbers or requirements to worry about. Just get some real physics advice about what subjects are good to know, what lab experience is good to have, etc. You can view your faculty advisor in my.harvard. (4) YOUR TASK: Email your faculty advisor to set up a meeting to discuss your classes and future plans and such. In addition to providing you with advice, your advisor will also provide you with the necessary electronic signature on your crimson cart. If you'd like to also meet with Prof. Georgi and/or me, by all means stop by zoom, but please do so in addition to (not instead of!) seeing your individual advisor. NOTE: Occasionally more than one email is needed to set up a meeting with your advisor. All of us let an email slip away now and then. So don't hesitate to send a second email after a day or two if you haven't heard back. Also, ***PLEASE CC THE FACULTY ASSISTANT** for your advisor on your FIRST email, unless you're sure that your advisor will get back to you right away (and definitely cc if a second email is required). This person can be identified by clicking on your advisor on the page: www.physics.harvard.edu/people/faculty<http://www.physics.harvard.edu/people/faculty> The Faculty Assistant is listed below the advisor's research blurb. If you have trouble getting a response from your advisor, let me know, and we can always switch advisors. (5) The Physics FAQ page is: https://www.physics.harvard.edu/undergrad/faqs-concentrators Please let me know if there's a topic you would like added. Enjoy the last few days of summer! DJM

SAVE THE DATES - Steven Chu, April 24, Colloquium | April 25, Lee Historical Lecture in Physics

by Davis, Jolanta M.

Steven Chu William R. Kenan Jr. Professor Professor of Molecular and Cellular Physiology and of Energy Science and Engineering Stanford University 1997 Nobel Prize in Physics [cid:843025f2-b1d7-436d-9363-109d359c704e] Harvard Physics Colloquium "Entropy, molecular motors, and non-thermal equilibrium statistical physics" Monday, April 24, 2023, 4:30pm (Colloquium Tea served in Jefferson 450 @ 3:30 PM – Please bring your own mug if you have one.) Jefferson 250, 17 Oxford Street, Cambridge, MA and zoom (see the link below) The transport of molecular cargos in neuronal cells is analyzed in the context of new developments in entropy and statistical physics. Our development of very bright optical probes enabled the long-term single tracking of molecular cargos in live neurons. The number of active dynein motors transporting a cargo is found to switch stochastically from one to five dynein motors during the long-range transport in neurons. Our probes allowed the observation of individual molecular steps where the time between single steps is controlled by two temperature-dependent rate constants. This finding suggests that two ATP molecules are hydrolyzed sequentially during each dynein step. The measured fluctuations can be described by a steady-state non-thermal equilibrium temperature, Teff as high as 6× Tcell = 6×310 K, and inversely proportional to the number of motors. Using the Fluctuation Theorem (proven in 1993) is consistent an “uncertainty principle” limit, ΔQ ⋅ ϵ2 ≥ 2kBTeff, where ΔQ = Teff ΔS is the minimum heat entropy needed to achieve an outcome with a given statistical precision. This theorem sets a lower limit to the heat energy needed to achieve a given precision in any physical operation. In the context of intercellular molecular transport, a smaller variance in the displacement of the vesicle demands a greater expenditure of energy. # # # 2023 Lee Historical Lecture in Physics "A random walk into laser cooling, optical trapping and beyond" Tuesday, April 25, 2023, 5:00pm Jefferson 250, 17 Oxford Street, Cambridge, MA and zoom (see the link below) A personal perspective of how laser cooling and optical trapping of atoms and biomolecules was developed. Emphasis will be given on how an elementary understanding of the physics at an undergraduate physics level led to success in initial successes. Once the basic tools of optical molasses and optical trapping were developed, more random walks into polymer physics and biology will be described. # # # Steven Chu is Professor of Physics, Molecular and Cellular Physiology, and Energy Science and Engineering at Stanford University. He received the 1997 Nobel Prize in Physics for laser cooling and trapping of atoms. Other contributions include the first optical tweezers manipulation of biomolecules, precision atom interferometry based on optical pulses of light, and single molecule FRET of biomolecules tethered to surfaces. He is now developing and applying new methods in molecular biology and medical imaging, materials science, and batteries. Previously he was U.S. Secretary of Energy, where he began ARPA-E, the Energy Innovation Hubs, and was tasked by President Obama to help BP stop the Macondo Oil spill. Previously, he was director of Lawrence Berkeley National Laboratory and Professor of Physics and Applied Physics at Stanford, and help initiate Bio-X, that linked the physical and biological sciences with engineering and medicine. Before Stanford, he was a department head at Bell Laboratories. He was past president of the American Association for the Advancement of Science, a Senior Advisor to the Directors of the NIH and the NNSA. He received an A.B. degree in mathematics and a B.S. degree in physics from the University of Rochester, a Ph.D. in physics from the University of California, Berkeley, has 35 honorary degrees, and is a member of the U.S. National Academy of Sciences and 8 foreign academies. # # # David M.

let's not lose physics night

by Georgi, Howard

Physics Night is a wonderful and unique Harvard institution, but it exists only because the Department allows us to use the beautiful space of Jefferson 250. That could change if we don't do a much better job of cleaning up. When you leave, be sure to clean up your area and remind your friends to do the same.
