1/18 tue lab spitwads and curve fitting[edit]
 Physics_and_Astronomy_Labs/Uniform_acceleration_tapping_basketball_with_spitwads Let's just look at the curve fitting question today. Instructor opened Excel and copy paste the spreadsheet. Found standard deviation.
 Did basketballtennis ball energy exchange using Earth's gravity.
Important announcement[edit]
Tuesday's and Thursdays are lab days and I need to take attendance. Usually this will be in the form of a 1page report on blank typing paper. Leave a 3/4 inch margin all around and do not include your real identity inside that space.
 At the very top (inside the 3/4 inch margin where it can be deleted): First last name and date.
 At the very bottom (also in the margin where it can be cut): Name of today's lab and real name.
 In the lower right hand corner, but outside the margins where it will be seen by viewers, you are strongly encouraged to write "I release to public domain  username" This way you or I can post to commons. I will not post handwritten diagrams without your permission.
 Within 24 hours you need to start a journal inside your log's .S personal subpage. Write a one sentence summary of every lab that you attend.
You need to follow the aforementioned instructions so that I can give you a good lab grade
 Class discussion: It would be easy for you to copy somebody else's lab report. How can I make this not sound so bad?
 Put this into your best prose in your personal subpage (i.e. your .S page). This is a high priority task.
1/20 Wed (lecture) PREPARE FOR TEST ONE WEEK FROM TODAY[edit]
 Can you all get to Wright State University Lake Campus/20161/Phy2400?

 Ear training to hear the need for the equal tempered scale.
 What about the 5:7 resonance?
 Two problems: 7 is a large prime number, and also 5/7≈10/7 (both close to the square root of two, or the logarithmic midpoint of the octave (factor of 2). As far as I know, nobody has investigated whether the proximity of two ratios of nearly the same order could cause this interval to sound harsh.
 Download three versions of the Devils tritone: 10:7 (617.49 cents)  7:5 (582.51 cents)  √2:1 (600 cents)
 La danse macabre is one of many musical works that features this interval of dubious consonance.
 Wikipedia:Scordatura describes the alternate tuning of the solo violinist that replaces one of the fifths by a fourth. See also Wikipedia:Danse_macabre_(SaintSaëns) for this rendition on commons.
 See Wiktionary:macabre for the definition and pronunciation of this word.
