1/18 tue lab spitwads and curve fitting

• 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 basketball-tennis ball energy exchange using Earth's gravity.

Important announcement

Tuesday's and Thursdays are lab days and I need to take attendance. Usually this will be in the form of a 1-page 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

• Can you all get to Wright State University Lake Campus/2016-1/Phy2400?

3/13 Newton's Dark Secrets

Questions posed by students

11 minutes: Who was Newton's roomate? what college? How long there? What coincidence is involved with the year somebody died and/or was born? How did Newton disagree with Descartes? What did Copernicus have to do with Astronomy at the time? What interested Newton as a child? Newton was interested in predicting something very important. What? When will it happen? 26 minutes What interested Newton about Alchemy? How did Newton's telescope differ from previous ones? What first triggered Newton's feud with Hooke? Where did Newton get the word "gravity"? Why did Newton leave the univeristy and go home? Did the university close when Newton left? At what age did Newton invent calculus? What was the magnification of Newton's telescope? What discovery led to Newton's invitation to join the Royal Society? afterwords: Why did Newton take up Alchemy? How have historians viewed Newton's efforts in Alchemy? People know great truths in the ancient past. Greek myths were encoded recipients. The green lion and sordid whore. File:Glacial striation 21145.JPG The net was produced. Alloy with striated netlike surface. 34 minutes

3/24 Centripetal force lab

instructions

Sketch the device in hanging mode and in swinging mode. Make two different sketches in "profile" view (i.e., from the side).In hanging mode, a mass, M, is attached by a string over the pulley. Label the hanging mass M. Do not sketch the counterweight, but label the rotating mass as m. Label the radius of orbit as r. Sketch and label the horizontal and vertical support rods (labeling both as "rod:", as well as the spring. Label the force that the spring exerts on the rotating mass as Fs. What direction does this force go? In the rotating mode sketch, include the pointer rod. In rotating mode the object is moving at speed v, place that letter on the diagram. What is the purpose of this pointer rod? (Hint: remove the hanging weight M and rotate) Why is it important that the two support rods, the spring and the vertical string to m make a perfect rectangle? Make two free body diagrams: (1) when it is rotating with the shape a perfect rectangle and (2) with the shape not a rectangles. Why is the net force in the x direction not zero? Write down two equations for Fs. Neither involves the "spring constant". Select from your list of variables: m, M, g, r, v, a. Your working equation is ma=Mg. Two can be measured and one is known. Write down these values: m=?, M=?, g=9.8ms2. The class measured m=.4558 kg, and M = .211 kg.--> How are we going to measure a? Force divided by mass is one answer, but to verify we need an independent measurement. Can we measure v if we know period. Let the period (of one revolution) be called T. It is easier to measure the period of 20 revolutions. Class got 20T = 26.8 seconds. Calculate r, v, and a+ r= .18m, v=? and a=?

Musical harmony

• Why Bach sounds funny on the piano (talk)
• Ear training to hear the need for the equal tempered scale.
• What about the 5:7 resonance?

1. 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.
2. Download three versions of the Devils tritone: 10:7 (617.49 cents) - 7:5 (582.51 cents) - √2:1 (600 cents)
3. La danse macabre is one of many musical works that features this interval of dubious consonance.
4. Wikipedia:Scordatura describes the alternate tuning of the solo violinist that replaces one of the fifths by a fourth. See also Wikipedia:Danse_macabre_(Saint-Saëns) for this rendition on commons.
5. See Wiktionary:macabre for the definition and pronunciation of this word.
