Arcminutes of longitude conversion to meters


This lab had a cold open in the field against the risk of rain. High humidity made this a tough morning measurement run. This was the view east from the starting point.

Launch coordinates.

Due to the flying start at 8:00, only three students were present for the measurements.


Thirty meters was problematic: smack dab in the middle of the entrance road

Sixty meters was under the Terminalia catappa.

240 meters was just a few centimeters beyond the sheet metal fence for the new learning health center. Upon return to the classroom much of the rest of the class was present. Since three had done the heavy lifting of gathering the data in the heat and humidity, I tagged on +10 to 071. Those who had 10 for finding me wound up with 20 out of 10 possible. Those who did not find me had their excused changed to 10/10, which provides a small boost. 



All board work was post hoc.

With clouds building, I went for a second cold open at 11:00. The class launched with four. The morning route had proven functional and so I opted to repeat that route. 


The line from E 158° 09.500' extends East for 239 meters (ground measure with measuring wheel).

The measurement at 30 meters was a "read and go" to get out of the road.

At the 60 meter mark.

Making readings at the 60 meter mark.

Looking forward the new line is functional. The ground is not as sodden as the field in front of the men's residence hall. When the health center is completed the 240 meter measurement should be possible, perhaps more.

Plotting polar coordinates in Desmos and a vector addition demonstrator

Image
In an earlier post I noted that Desmos did not directly plot polar coordinates. Not only was I incorrect, but Desmos responded to my blog to correct me! Although I had at some point seen that one could define a function f(x)=3x+5 and then have Desmos calculate f(6), I had not absorbed how this might be used to plot polar coordinates. The above works beautifully . Realizing that I could effectively program Desmos, I applied this thinking to demonstrating how to add two vectors when given the magnitudes m and the direction angles theta. The graph calculates the i and j components for the two vectors and then adds the vectors, graphically displaying the result while also providing information on the magnitude and direction of the vector sum. m1 and theta1 are the magnitude and direction angle for one of the two vectors, m2 and theta2 are the magnitude and direction for the other vector. All four are dynamically interactive and can be changed. The diagram purports to illustra...

Traditional food dishes of Micronesia

Image
Clara, Jennette, and Joanie presented ground hard taro cooked in an umw, effectively a hot rock oven. Pohnpeian: rotama. Pingelapese: sero. Mwoakillese: rodma. Mortlockese: Amahd. Kosrae: rodoma. After cooking in an umw the rotama is pounded with the petiole of a palm frond. Rotama is made from hard or swamp taro, known as mwahng on Pohnpei, mweian on Pingalap, pula in Mortlockese, and pahsruhk on Kosrae. In traditional times on the outer islands the women had primary responsibility for tending the taro while the men handled fishing and climbing tasks. Joesen and Noeleen presented fermented breadfruit from the outer islands of Yap such as Woleai and Eauripik. The raw ingredients were actually brought in from Yap, Noeleen prepared the maare.  The leaf wrap is ti leaf - Cordyline fruticosa. Pauleen, Barnson, Trisha, Verginia, Con-ray, and Maylanda from Kitti, Pohnpei brought in mahi umw, koahpnoair koakihr, and uht sukusuk. Above is breadfruit umw, mahi umw, o...

Setting up a boxplot chart in Google Sheets with multiple boxplots on a single chart

Image
The  Google Statistics  add-on for Google Sheets can display multiple boxplots in a single chart. The key is the layout of the data. One column should be the variable by which the data is to be grouped, the other column should be the data to be box plotted. Set up the Statistics add-on with the data to be plotted as the variable, and the grouping column as the "by" variable. In this image I had deselected all but the boxplot option, the result was the appearance of the Moment, Standard errors, and Confidence intervals options. The default is apparently a 95% confidence interval for the mean. The result is multiple boxplots on a single chart with a common scale. The new tab that is created also quotes 95% confidence intervals for the mean. Note that as of 2018 the Google Statistics add-on cannot be found by search in the add-ons. In addition, as of May 2018 the add-on no longer verifies, possibly due to the add-on not having been updated since August 2017. One may ha...
