The following can also be found at: http://www.chemistry.ohio-state.edu/~rzellmer/chem1250/chem1250_intro.txt Hello. I am Dr. Zellmer. I am teaching Chem 1250 Spring semester. I apologize if you are getting this and you are not signed up for Chem 1250. I got the current roster with your e-mails from Buckeye Link. Please read the WHOLE message and any to follow. This is just a "little" note to let you know a few things about 1250. Read ALL the following and it will make things easier for you when we start on Monday, 1/11/21. I will "see" you in lecture on Tuesday. You WILL meet for lab the first week. It will be a digital lab. The TA will send you information and a Zoom link. Your first lab will consist of check in and exp 0 (ZER). You will need your manual and notebook during lab. You can use PDF of the manual (2020/2021 edition) for this. You MUST have the newest edition of the manual. Several changes have occurred for this year. Without the newest version you may do the wrong things for lab. You will cover some general aspects of lab, including safety procedures and equipment, notebook and report requirements, using a pipet and buret, academic misconduct, etc. Your TA will give everyone a new pair of goggles at your first in-person lab. I will send an e-mail about the procedures you must follow when you go to lab. Your TA will have additional information. If you can't get a lab manual before the first lab don't be too concerned. I've posted the manual pages for exp 0 on Carmen. If you can't get a lab manual before the 2nd exp you can find the manual pages for exp 1 on Carmen (see Lab 1) as well. You will absolutely need the manual and notebook before the exp 5. Again, you MUST have the 2020/2021 edition of the lab manual, even if you are retaking the course from a previous semester. The notebook policy is different for this semester. Please see the syllabus and the Laboratory section below (section (g)). If you are on the wait list you are also receiving this e-mail. If you are still on the wait list when classes start please come to lecture and speak to me after the first lecture. Class notes are available (item 1a below) on line. They are not required but having them will make your life easier. The notes are up now. There may be times I make corrections or changes and I will let you know either ahead of class or in lecture. 1) I have a web page. The address of my homepage is: https://www.asc.ohio-state.edu/zellmer.1 This is my main homepage. You will find my office location and hours. However, I will not likely be in my office much, if at all, this semester. The easiest way to reach me is via e-mail. Much of the material is PDF files so you'll need a PDF reader (such as Adobe Acrobat). Most web browsers generally already have AR as a plug-in or you can easily find and install it. My web page is optimized for viewing with Firefox. If you scroll down a little you'll fine a link to our calculator policy and then directions to my office and bookstore locations. Then you'll find links for how to study. Read the one for Chem 1250. You will need to approach this class in a way which is probably different than you're used to. This is a tough course, partly because of how fast we'll be moving through the material. I don't have a link for Carmen since most everyone knows how to reach it. I mainly use Carmen to keep track of your grades. You won't have any grades entered until about the 3rd week of the semester. It is a good idea to check your grades periodically throughout the semester to make sure your TA has correctly entered your grades. This semester with online lectures you will find the pre-recorded lectures on Carmen and then the Zoom lectures there after lecture. These are in the "Lecture" link in the "Modules" in Carmen. More details below. The lab information with due dates is on Carmen. The office staff will make announcements via Carmen, many of which I will also have on my web page and send via e-mail. Make sure you set up Carmen properly so these announcements will be e-mailed to you so you don't miss any. You will also find the publisher's Solutions Manual to the 11th through 14th editions end-of-chapter homework problems in Carmen (see item #2 near end of this message). There's a Homework module where you'll find instructions and links to the various editions. You will not be able to copy them or print them. This semester you will be taking four on-line quizzes in Carmen at the start of the semester. There's also a lab safety statement on Carmen you have to do. There are also pre-lab and post-lab assignments for most labs on Carmen. Some of these will actually take you to an external website. This is explained in more detail below under the Quizzes section. If you scroll down a little further you will see a link which will take you to our 1250 course. There you will find the syllabus for the semester. Take a look at it. This the official syllabus. You can find it on Carmen as well. I won't spend a lot of time on it during lecture. The TAs will go over some of it in during the first lab. You are responsible for reading it and knowing the information it gives. There's also an audio/video version in which I go over the syllabus and other things in details. You will also see several other links. Take some time to explore the site. This is where you will find a lot of useful info for the course. a) Notes This link has the notes I will be using during the semester. I use overheads. The notes are a copy of my overheads. I cover a lot of things in lecture and it can often be difficult to keep up and make sure you've written everything correctly. I will usually cover 30-40 pages per lecture. I suggest you get the notes and bring them to lecture. It will make it much easier for you to keep up. You will be able to keep up with the examples and write other things I will say that aren't in the notes. Of course you should still come to class or you will miss my pearls of wisdom and more importantly some of the tips I give for things you will probably see on the quizzes and exams. If you have an iPad or other tablet computer there are apps you can purchase which allow you to not only have the pdf files but to also write on them and record the lecture at the same time. This makes it very convenient for later when you are studying and perhaps wish to hear what was said in lecture you can easily get to that part of the lecture if you set a bookmark on the pdf. There's several for the iPad such as "pdf-notes", "notes plus", "PapePort Notes", "Notability", "Evernote", "Onenote". Some of these are also available for Android tablets. "Notability" is installed by default on the university supplied iPads. I also suggest you skim each week's chapter in the book and the notes corresponding to that chapter before we cover it in class (at least 5 sections per lecture). It will make what I'm saying during lecture a little easier to follow. Also, you will be able to keep up with me in class, especially if you are taking notes by hand. It should only take 20-30 minutes for you to skim the chapter's material (don't worry if you don't understand it). 1) Lecture and Zoom Videos I will be putting up pre-recorded videos for the material covered each week. You will find these in the "Lecture" module in Carmen. Each lecture link may or may not be completely covered on the day which their included. You should watch them before that day. During the lecture time I will use Zoom. My hope is that if you have looked at the pre-recorded lectures we won't have to cover everything in the pre-recorded lectures over again. Instead, we can use most of the lecture time going over some of the more difficult topics and examples again, have you ask questions about what you watched previously, etc. I will often pause and ask questions and wait a short while for people to respond. This will only work if most everyone watches the pre-recorded lectures before the lecture time. b) Homework (End-of-Chapter Exercises) - no course credit Here you will find the textbook homework assignments for each chapter. These are the end-of-chapter (EOC) exercises. As an example, for chapter 1, when it shows 1, 2, 5 it means 1.1, 1.2, 11.5, etc. at the end of the chapter. The solutions from the Prentice-Hall Solutions Manual (solutions to ALL end-of-chapter problems) are on the Carmen course page. Go to the "Homework (End-of-Chapter Exercises) and Solutions Manuals" module and then "Publisher's Solutions Manuals". There you'll find instructions for accessing these for the 11th-14th editions. The best way to learn the material in this course is to do ALL the homework I assign. This means YOU must do it and do as much of it on your own without having to follow what's done in the solutions. If you need to look at the publisher's solutions manual (on Carmen), at some point you need to go back and do those problems again or better yet some of the other problems, on your own. You will have to do your own work on the quizzes and exams so if you haven't learned the material you will find yourself in trouble on the quizzes and exams. You should do a problem and then check to make sure you got the correct answer and did it in a correct way. Getting the correct answer for the right reason is important. You need to make sure you get each one correct before attempting the next question. You don't want to do a whole bunch of problems only to check them and discover you did them all incorrectly. Then you have to redo them and you wasted a lot of time doing them wrong the first time. I don't collect or grade this homework. It's up to you to do it but I can pretty much guarantee you will not do well on the quizzes or exams if you do not do the assigned problems from the book. We do NOT do on-line homework. However, I've set up Sapling Learning so you could use it as a tutorial if you desire. It costs $42 but could prove useful if you are having trouble with the material. However, it does NOT take the place of the homework I've "assigned" from the textbook. Those questions tend to be more challenging and more like the exam questions. You will find a section in Carmen which will explain how to set up an account. c) Mandatory Quizzes There are 4 MANDATORY quizzes on Carmen. A couple of these deal with the course on the whole. There are also other quizzes or forms you must take dealing with lab. These are not part of your final grade. There is a pre-assessment quiz which tests your incoming chemistry knowledge. It must be completed by 11:59 PM on Sunday, 1/17/21. You MUST take the Academic Misconduct (COAM) and Syllabus quizzes on Carmen and get a 100% by 11:59 PM on Sunday, 1/17/21, or you will FAIL the course. Once Carmen opens you can take them but you may want to first read the syllabus. You can take these quizzes multiple times and MUST get 100%. Since it allows multiple tries, Carmen may still state you have quizzes to take even after getting 100% until after the quizzes close on 1/17/21. Once you get 100% on each of these you are done with them. It is your responsibility to make sure you've taken these by the deadline and have received 100%. You MUST take these even if you already have done so in a previous course. There's a lab safety quiz (GateKeeper Quiz) you need to take by 11:59 PM on Sunday, 1/17/21. You can find the answers to the quiz questions in the lab manual and lab safety statement. You must get a 100% on the safety quiz. You must sign the lab safety statement before your FIRST in-person lab period. It is due by 11:59 PM, Sunday, 1/24/21. d) Quizzes This could change depending on the time I have to do this. I will let everyone know if the format changes before the first quiz. You can use your notes, textbook, lecture videos when taking the quizzes (and exams). However, you MUST work independently. You can not get help from anyone or provide help. You can not use the internet for help or upload any part of the quiz or your answers to the internet. You will have 3 quizzes during the semester. Right now the current plan is to have timed quizzes on Carmen. They will be 30 minutes long with a buffer of 10 min (40 min total) so you can take pictures of your quiz and work and submit it. You will not get credit if your work is not submitted, even if your answers are correct. They will be 7-8:30 PM (EST) on Thursdays, in the weeks shown on page 2 of the syllabus. Essentially, you're taking a "paper" quiz at home. The first question has links to the quiz (PDF file). The easiest thing do is to download the quiz to your iPad and work it in Notability. Then save it as a PDF (.pdf) and upload it in the 2nd question in the quiz. You can use some other tablet/computer/app. You can print the quiz or write it on paper (preferably unlined printer paper). Then take pictures (or scans), combine them in a single file and submit it as a PDF (.pdf). If you're going to do it one of these ways you want to try taking pictures/scans and making a single PDF file. The quizzes will generally cover what was presented in the weeks before the quiz. I will let you know in class the week before the quiz what it will cover. This info will also be available on this section of the web page and I will e-mail it to you the weekend before each quiz. Even though you don't have a recitation with a quiz every week it is a good idea for you to treat things as if you do. For instance, if your lab is on Tue. pretend you would have a quiz on Thur. and study each week with that in mind. That way when the actual quiz and exam comes up you will be better prepared for it. If you leave everything until the last minute you will find that you won't be able to learn it very well and you won't do well on the quiz. There are NO make-up quizzes. If you miss a quiz you MUST have a written excuse covering that conflict on the day and at the time of the quiz. If you're sick you'll need a written excuse from a doctor (in which case the excuse MUST state you couldn't be at school the day of the quiz). Speak to me immediately. Sometime after all the quizzes are completed for the week, I will post solutions to the quizzes. You should look at these to make sure you know what you are doing. Sometimes people can get the correct answer with the wrong line of reasoning. You want to make sure you understand the concept so when you see something similar you get it correct. If you are using the wrong reasoning and happen to get a correct answer in one case that may not happen in another case. e) Practice Exams This area of the web site will contain the practice exams and the solutions to these exams (everything explained in detail - whether you want to know it or not). They are not available as of yet. I will let you know when they are ready. While your exams won't be identical to these practice exams they will be very similar. f) Exams This area contains exam information, like date and time of the exams and reviews. I will be holding a review session before each exam (generally on the Sunday before exam week). The exams will be given in the evening on Thursdays. The actual dates and time are given in the syllabus. The exams are multiple choice. No partial credit is given. The exams will be given using Carmen. There will be instructions on Carmen concerning the exams. The questions and answers will be randomized. The most important thing is you can NOT return to a question. If you skip a question you can't go back to it. That means you will miss it if you don't answer it before moving on. I know this could be a problem for many of you, especially those of you who don't like skipping problems (just guessing). I will say if w/in about a minute you can't figure out how to answer the question you need to make a guess and move on. You want to make sure you get to all questions. If you get stuck on one and take too much time so you can't get to all questions you might not even get a chance to do ones you could easily answer. The exams will NOT be returned in any capacity. However, Carmen will give feedback about the average, your score, etc. If you have a conflict with an exam you can sign up for an alternate exam. If possible you should sign up for an alternate to be given the same day as the regular exam. You do this on Carmen. See the "Exam Attendance Policy". If you miss an exam, a make-up will be given. The make-up policy and procedure is in the syllabus and details can be found on Carmen. Essentially, if you miss an exam you MUST register online in Carmen by the dates given there, which could even be the night of the exam. You should also contact me when this happens so I know someone has missed an exam since I will need to get one prepared. Without approved documentation, students will receive a grade penalty of 15%. This MUST be in the form of a WRITTEN excuse covering the DAY of the exam. Details of what is considered a valid excuse can be found on Carmen. This applies to both the alternate and make-up exams. It is NOT a good idea to "make up" an excuse simply because you are not ready for the exam that day. If you are not ready the day of the exam, you will not be any better prepared a few days later. If you are truly sick, see a doctor and get a note. The rest of us do not want you there to make us sick. Besides, once you start an exam that is your score, even if you tell me later you were not feeling well. Tell me before the exam and I will tell you to see a doctor and get an excuse. Make-up exams may be harder than the regular exam. After all, you've had more time to study for it. Whether you use that time or not is up to you. g) Laboratory There are COVOD-19 procedures you will have to follow in lab. These will be conveyed to you in the syllabus and in the Lab Policies and Procedures Document. This can be found on my webpage and Carmen. Your TA will go over this during the first lab period. You MUST get 50% in lab (50% of lab pts) to pass the course, no matter what your scores on the quizzes and exams, no exceptions. Please make every attempt to make it to the in-person labs. We have only three of these throughout the semester. We really don't have a mechanism for making these up this semester. If you do miss, contact me right away (I'm both the lecturer and lab supervisor) about what arrangements can be made. The first lab period will be check-in and exp 0 (ZERO). Your TA will guide you through this period, discussing general lab policies and procedures, safety, how to write your procedure, what your notebook should look like, the lab report, etc. Bring your manual and notebook. You will record what they cover in your notebook. If you took 1250 previously and are taking 1250 this semester you MUST have the new 2020/2021 lab manual. You can NOT use a previous edition of the lab manual. You will find general lab info and info about each experiment at this link of my webpages. I've posted changes to the lab manual (not much at this time since the exps have been done for some time and the manual has recently been updated). I've also posted hints that will make the lab easier to perform. You should look at this before going to lab. This is already available for the entire semester, although I'm still making changes. I'll post the pre-lab and post-lab assignments and lab questions you are suppose to answer for each lab report. The pre-lab and post-lab assignments are generally found on Carmen (see syllabus). These may be in the form of a quiz and are labeled as such. The pre-lab assignment on Carmen will generally consist of a link which will take you to an external site for the pre-lab. These can also be reached from the links in the syllabus or my web page in case Carmen is down. The link is, https://uglabs.cbc.osu.edu/1250/ This site also has a lot of other very useful information about lab. Some post-labs are on Carmen and are in the form of quizzes. There is data entry for some pre-labs and labs (see below). For the in-persn labs, you must read the experiments before lab and prepare the notebook. You get 10 pts for the notebook each week. For the digital labs your notebook score will be your attendance and participation in lab. Some of the 1250 labs take almost the whole period and you may not finish if you aren't prepared. Also, it makes it harder for the TA to help everyone in lab if they are spending all of their time helping one or two students who are not prepared. This isn't fair to everyone else in lab. Also, if you aren't prepared you could cause an accident and get injured and perhaps injure others around you. There are also lab videos for most exps you must watch at the beginning of each lab period before being allowed to do the exp. Many of these videos are part of the on-line pre-labs. You can also get to some of them from the undergraduate web page link above. You still must watch them at the beginning of the lab period or watch the TA presentation. There are prelab assignments you must complete before the start of the lab period. If you do not complete them before the beginning of lab they will be considered late and not graded (you get zero pts). You can find the help for these questions and the equations you need in the lab manual. You will often have to refer to the Discussion, Procedure and Data Analysis sections. Read these sections and write the procedure in the notebook before attempting these. These can be found on Carmen or the following link (Carmen goes here), https://uglabs.cbc.osu.edu/1250/pre-postlabs.php These have a time limit. READ the general instructions and the "Terms and conditions of use" before attempting any pre-labs. There are also specific instructions for each pre-lab and data-entry page. For exps 5, 14, and 16 there are general questions about the experiment. There is also a simulation of the post-lab data entry. This consists of a "sheet" with data that looks similar to the report sheet for the exp. This "data" consists of randomly generated numbers in the ranges which you will obtain for your experimental data. This is supposed to represent the data you collect for you unknown while doing the exp. You are supposed to take this data and do the necessary calculations. The pre-lab has you watch some videos, you answer questions pertaining to those and the discussion and procedure from the lab manual and then do a numerical pre-lab given randomly generated numbers in the ranges which you will obtain for your experimental data. Also, for exps 1, 5, 6, 14 and 16 there is post-lab on-line data entry. This can be reached from Carmen or the same link as above. For these post-labs you will enter your data and calculated values This is for grading purposes. You still need to turn in a lab report, including the report page from the lab manual. My suggestion is for you to fill out the report page from the manual and your calculation page and then do the on-line data entry. These are due when the lab report is due. If done after the due date for the report late points may apply. For some of the other experiments there is a post-lab assignment (quiz) on Carmen. These, like lab reports, are due 1 week after completing the exp. The post-lab quiz on Carmen will receive zero credit if done more than 1 week after completion of the lab (i.e the lab period when the report is due). This information can be found in the table on page 13 of the syllabus. NOTEBOOK: You are suppose to have your lab notebook prepared before lab. This is mainly the purpose and procedure (see syllabus for details). The procedure must be written in your own words. It MUST be done using BLACK or BLUE PEN. The TAs will check your notebooks at the beginning of the period to make sure you've written your purpose and procedure. If you have not finished this by the start of the lab period you could lose up to 60% of your lab notebook grade (worth 10 pts out of the total grade of 110). This depends on how much isn't finished. Please see the following links for how you might write a procedure (using exps 6 and 14 as my examples). http://chemistry.osu.edu/~rzellmer/chem1250/lab/notebook_proc_1250.pdf https://uglabs.cbc.osu.edu/gc-labnotebook/ For this semester there are several options for notebooks. At the end of lab you will upload a PDF copy of your notebook to Carmen, no matter what option you use for your notebook. You'll show your notebook to the TA before doing this. Then you can upload your notebook. Then you will clean your lab station as directed by the instructions in the Lab Policies and Procedure document and the TA. You will be allowed to use Notability on your university supplied iPads as your notebook. It is easy to save a PDF and then upload this to Carmen. This will be the easiest most straightforward option. If you use this make sure your iPads are fully charged and you bring your charger with you. Use the BLACK or BLUE pen. Treat this as if it were a paper lab notebook. Show this to the TA when you're done with the exp. You will then upload it. You can use new lab notebook or a cheap regular spiral notebook with grids or lines. You would then take pictures of your notebook pages and put them in a single PDF. Show your notebook to your TA and upload the PDF to Carmen. Once you've done this you'll need to clean your equipment and lab area. The TA will describe how to do this. Lab Reports: I have an example of a general outline of what a decent report should look like on the course web page. You will find this at, http://chemistry.osu.edu/~rzellmer/chem1250/lab/chem1250_sample_lab_report.pdf This example shows you pretty much what is expected in each section for a full report. You should also look at the following link for a complete example, https://uglabs.cbc.osu.edu/gc-labreport/ These will be turned in on line in Carmen. Instructions are on Carmen. It is your responsibility to make sure you've submitted the correct report in the correct format and with a correct file name and to make sure it has actually been submitted and isn't corrupted. After submitting it a box shows up near the upper right corner with the file name. Make sure it's there. Click on it and you should see your report. If you don't submit it again. You MUST get 50% in lab (50% of lab pts) to pass the course, no matter what your scores on the quizzes and exams, no exceptions. Please make every attempt to make it to the in-person labs. We have only three of these throughout the semester. We really don't have a mechanism for making these up this semester. If you do miss, contact me right away (I'm both the lecturer and lab supervisor) about what arrangements can be made. The first lab period will be check-in and exp 0 (ZERO). Your TA will guide you through this period, discussing general lab policies and procedures, safety, how to write your procedure, what your notebook should look like, the lab report, etc. Bring your manual and notebook. You will record what they cover in your notebook. If you took 1250 previously and are taking 1250 this semester you MUST have the new 2020/2021 lab manual. You can NOT use a previous edition of the lab manual. h) Helpful Tidbits Here you will find some of what I hope are some helpful faqs. Many of these were generated as answers to student questions over the years. Take a look at what's here and remember to look here first before e-mailing questions. You will find some of these same links elsewhere on the class web pages. i) Tutorials This section contains links to some other web sites, both internal OSU Chemistry links and external links. I make no guarantees as to their accuracy and have no control over such. j) PHET and Molecular Workbench These sites contain what looks to be some useful simulations. Again, I make not guarantees as to their accuracy or helpfulness. k) Corrections Here you will find corrections to the book, notes, homework solutions, etc. Always check this link when printing notes, looking at solutions from the book or my web page. If you find any mistakes let me know so I can update this. This is still under construction. 2) You will find the instructions for accessing the publisher's solutions manual at the "Homework (End-of-Chapter Exercises) and Solutions Manuals" module link in Carmen. This manual contains solutions to ALL end-of-chapter (EOC) exercises in the textbook. It shows the setup and not just the answer. I suggest each time you complete a problem you look at the solution, even if you get the "correct" answer. Sometimes you can get the "correct" answer for the wrong reason. Faulty reasoning may work in one case but not another. However, don't use them as a crutch. Access to the solutions for the 11th - 14th editions are on Carmen. 3) If you miss your first lab, let your TA know as soon as possible via e-mail (CC me). If you need to change sections for some reason see the syllabus for instructions. 4) If you are still on the wait list please attend lecture the first week. You can't attend lab the first week if you are not officially enrolled in the class. You can check-in the 2nd week and still get exp 0 (ZERO) requirements completed (Notebook Exercise and Quiz). You can check on availability through Buceyelink the first week but must go through the Undergraduate office the second week of the semester (110 Celeste). 5) There is NO extra credit. Do not ask at the end of the semester to do extra credit because you aren't going to pass or get the grade you wanted. I'm sure you know during the semester whether you are doing okay or not. If you aren't sure then ask me. Getting 40% on the quizzes and exams is NOT okay. You are not likely to pass the course with that kind of performance on the quizzes and exams. Do NOT plan on your lab helping that much if you are doing poorly on the quizzes and exams. The lab is worth only 20% of your total grade. The other 80% depends on your quizzes and exams. Do not bother the TAs about your letter grade. They do NOT know the grading scale and do NOT speak for me. If you have a question about how they've graded a quiz or lab report speak to them within 1 week. After that time period they may not remember exactly why the took points off and will not be able to correct any mistakes they may have made in grading. See #6 below about regradng. It's likely that if you have over 90% for everything at the end of the semester you will get at least an A-. If you get less than 50% it is likely you will fail the course (i.e. receive a grade of E). The grades are based on a curve. However, that does not mean the class average will be a C. It is also based on the averages and curves from previous semester. That means the class average could be a C-, C, or C+ depending on how the class does this semester compared to other semesters. 6) Regrading. Any requests for regrading must be made within 1 week of the receipt of a graded lab report, quiz or exam. For lab reports and quizzes, it is best to ask the TA first before coming to me. This all must be done w/in the 1 week period. After that we won't entertain any questions about regrading. 7) I have a couple of links on my main web page about studying for this type of course. I highly suggest you read them. I will be sending the links in a follow-up e-mail. This course is very different than most courses you've taken. You will need to put in more time than you likely will in other courses (especially non-science or even some engineering courses) and well more than you put in during high school. 8) Cancellation Policy: I will NEVER cancel anything (class, lab, recitations, exams, etc.) via e-mail. The only time anything will be cancelled is if OSU cancels classes for the university (which you will find on OSU's webpage) or you hear from me via e-mail pointing you to a link on my homepage about the cancellation. If there's no link then it's not likely the e-mail was from me. If your TA is not in lab 5 minutes before when it's supposed to start please send one person to 110 Celeste or call the office at 292-6009. Do NOT leave. If your TA is not present for a Zoom lab please let me know via e-mail. If I'm not present for a Zoom lecture contact your TA. They will have my phone number. This is not likely to occur but they will be able to get a hold of me. A TA will never cancel a lab or recitation for any reason. They are not allowed to. These decisions will be made by me, the lab director, the department or the university. As a matter of policy, TAs are not allowed to make any changes to the syllabus or class requirements. I do everything I possibly can to make sure you get every class you've paid for. In 28 years of teaching I think I've missed fewer than 6 lectures. I'll be there or upside down in a ditch or have fallen down the stairs since I'm not going out a whole lot (so please let someone know if I don't show up for lecture so they can look for me). I guess that's about it. I will see you on Tue. 1/12 for lecture. I know you are looking forward to it and you WILL have a good time this semester (see, you are already laughing). It won't be so bad as long as you keep up. It will be terrible if you fall behind. We will do the best we can under these circumstances. We start very soon. You will be quite busy. For now, relax a little longer. Dr. Zellmer
