9/30	After much discussion with the TA's, and with input from students, question 18 (which asked the charge across the 4C capacitor with respect to the 1 C capacitor,) is being regraded to allow *two* answers as being correct.  'None of the above' *and* '0.52' since the correct answer was close enough to 0.52 as to have caused confusion.  Our apologies.  The regraded scores will appear on Sakai soon.
9/29	Student grades for the first exam are now accessible on Sakai.
9/29	The exam (first answer is the right one) is available on Sakai.  Solutions are coming.

9/22	Additional office hours:  Prof. Stewart, 9/26 Monday, 10 am - 2pm, NPB 2132 Prof. Kumar, 9/26 Monday, 2-4 pm, NPB 2160 Ben Hall, 9/27 Tuesday, 10:40 am - 1:45 pm, NPB 2220 Sanal Buvaev, 9/27 Tuesday, 10:30 am - 12:30 pm, NPB B39 (in the basement) Chungwei Wang, 9/23 Friday, 6:30 pm - ?

9/12	Your proposed Test I problem for extra credit is due to your TA by tomorrow, Tuesday, 9/13 by whatever method and time your TA has announced.
9/8	Some more about problem 10 that we discussed in 3rd period:  We were on the right track (y - y0 = voy * t + 1/2 ay * t**2) since indeed y-y0 = 0 does tell us that ay = - 2 * voy / t, and we did have the right expression for ay (just g+qE/m).  But somewhere I must have made an arithmetic error.  So just set ay = 2 v0y/t, plug in what you know for v0y and t, then calculate E from the ay you get.  (The problem is that 2 v0y/t is *really* close (but not ! equal) to 9.80.  so qE/m is a small number.) Note:  it's E field pointing down towards Telnar, so E and g-force are in the same direction, so it's g+qE/m. (plus sign)
9/6	Prof. Stewart's office hour is now 7th period on Mondays, at 1:55-2:45 pm, in his office 2132 NPB to better match with students needing help on their homework.  The old Friday office is canceled.
	In order to a.) give you a bit more time to finish the first homework and b.) to better align when the homework is due with when it was lectured on/discussion in recitation, we are moving the due date for all homework to Mondays at 11 pm instead of the previous Fridays.  This may take a while to permeate thru all aspects of the web site.
8/24	Sakai should be up and running (8/24; 9:45 am).  Old tests will be uploaded by next week.
8/23	A number of you have observed that PHY2054 is not yet up and running on Sakai.  This appears to be a question of authorization to allow us to add the student rosters.  Tonight at least (8/23) this will not get fixed.  We will keep trying tomorrow.  (At present, there is nothing except old tests to put on Sakai anyway.)
	to sign in on webassign the following code has to be used.. ufl 8560 3612
	Students with Disabilities: Students requesting classroom accommodation for disabilities must first register with the Dean of Students Office. The Dean of Students Office will provide documentation to the student who must then provide this documentation to the instructor when requesting accommodation. Then you must print out the PHY2054 Accommodated Test Request (ATR) Form for Fall 2011 (click here for the form). This form must be filled out by the student and returned to the Disability Reseource Center (DCR) at least one week before the first exam. The Accommodated Testing Service (ATS) at DCR will then administer all the exams.
	PHY2054 Tea and Cookies Session: Starting on Tuesday August 30 Professor Kumar will host a "tea and cookie" session every Tuesday at 5:00pm in 2165 NPB. Join him for tea, cookies, and help with the physics problems.
	WebAssign Passwords for UF-ID's with Leading Zeeros: If your UF-ID has leading zeros you have to omit them in your WebAssign password. For example, UF-ID = 0XXXXXXX WebAssign Password = XXXXXXX and UF-ID = 00XXXXXX WebAssign Password = XXXXXX. Hope that's clear.
	PHY 2054 e-Learning Website: The e-Learning WEBsite is now up and running.
	The first on-line homework assignment is due by 11:00pm on Friday Sept. 2, 2011. You must login to WebAssign using the username = Your Gatorlink UserName, institution code = ufl, and initial password = Your UF-ID (8 digit number). To log into WebAssign you will also need the access code that comes with your textbook (see the instructions in the syllabus).
	Quizzes begin in the discussion sections on Monday and Tuesday September 5-6, 2011.
	Discussion sections start on Wednesday August 24, 2011.
	Lecture classes start on Tuesday August 23, 2011 (period 2 & 3) in 1001 NPB. The class schedule shows the lecture material covered, exam dates, and the on-line homework problems.
	Quick Links: Here are some important links for PHY 2054 Fall 2011. Course schedule. Overall grade formula. WebAssign on-line homework. PHY 2054 e-Learning WEBsite. PHY 2054 E-mail should be sent to phy2054@phys.ufl.edu.
