Color and light

The session opened with 스텔라장(Stella Jang) - Colors as the pre-9:30 AM opener followed by the Limits of Light video from Austria. 


Launch of Limits of Light was at 9:30 AM sharp to an empty room. Necessary as the morning session was fitting in both Limits of Light and CD spectroscopes.


The weather was good for the CD spectroscopes with bright sunshine between cumulus clouds associated with tropical storm 09W Bavi passing to the north of Pohnpei.

The Tripltek was deemed unsafe for use as the battery has expanded with enough force to crack the armored case. The Tripltek was factory reset although IT recommended not even turning the unit on. 

While the video ran, the CD spectroscopes were brought out.

Following the video the colors seen were listed by the students. No student listed indigo, which would have led to Niki - Indigo but the time was too tight. Coverage of ROY G. BIV and indigo was done as the period wound down.


The laboratory session did not include the Physci 112 color playlist, opting instead to display gray on the Doogee Fire 3 Pro. No gray. An explanation of the biophysics was done on the board. The logic being that the students had just been through an hour long video in the morning session. During the regular term the Limits of Light is shown on Monday, CD spectroscope on Wednesday, and the lab on Thursday. To buffer the 8:00 AM start of the laboratory and late arriving students, the playlist is useful. During the summer this is not necessary. 

This term a gray shirt was used to show that gray is not produced by a cell phone screen. Again the Doogee Fire 3 Pro was pressed into service as the pixels are larger than on a Google Pixel 10 Pro. This helped compress the period and the lab wrapped by 13:00 on an 11:30 start. During the regular term, however, the playlist should be used as this allows time for late arrivals to settle in.


No gray is coming off of the Smartboard screen nor the screen with which you are viewing the Smartboard displaying my gray shirt.

Austin, Senilo, Ellinae, Jenry-Thor, and Camridge. A curious effect occurred. One student left, which is not unusual as students do not need permission to go to the washroom. The a couple others left. And never came back. I think they thought the first 12 questions were the whole laboratory. The loss of a significant number of students half way through the lab was surprising and unanticipated.

In lieu of the videos, the explanation was sketched out on the board for gray and yellow from RGB

Experimenting with the PlantNet and iNaturalist apps

Image
The application of image recognition technologies as the back end to botany apps is providing increasingly relevant search results. Over the recent winter break I began looking at whether the apps now available might be useful to the ethnobotany class here on Pohnpei. Some apps had a more regional focus in the past and were better at north american or european plants. Pohnpei has a both unique indigenous plants and many introduced plants from around the world -  a challenging environment for any image recognition system. A student working with a plant identification app for the first time My criterion was that the app had to be appropriate for use in my classroom. The app could not contain advertising and the app had to be free, my students typically do not have the ability to pay for an app. The app would also have to be fairly small as my students often use phones with limited memory and processing power. I settled on PlantNet and was impressed with the ability of the a...

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...

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...
