Selected Topics started our Physics Unit after reviewing for our Astronomy Test tomorrow. Catapult Lab on Thursday and Friday.
Most students are finishing Problem 11 in qBASIC. We will start checking problems tomorrow. We will start graphics and animation before heading out to fall break.
After school, we ate an early supper with our son John. Got home in time for a walk. We still have a lot of wild flowers blooming but the wingstem and ironweed are finishing up. Below are some wildflower picts from Sunday and this evening ... lots of small flower asters blooming and in the woods and borders of the woods, an abundance of White Snakeroot ... use be a seriously poisonous plant.
White Snakeroot I think ... or Late Thoroughwort ... above and below
Wikipedia-
White Snakeroot contains the toxin tremetol; when the plants are consumed by cattle, the meat and milk become contaminated with the toxin. When milk or meat containing the toxin is consumed, the poison is passed onto humans. If consumed in large enough quantities, it can cause tremetol poisoning in humans. The poisoning is also called milk sickness, as humans often ingested the toxin by drinking the milk of cows that had eaten snakeroot.
During the early 19th century, when large numbers of European Americans from the East, who were unfamiliar with snakeroot, began settling in the plant's habitat of the Midwest and Upper South, many thousands were killed by milk sickness. Notably, milk sickness was the cause of death in 1818 of Nancy Hanks Lincoln, mother of Abraham Lincoln.
It was some decades before European Americans traced the cause to snakeroot; although today Dr. Anna Pierce Hobbs Bixby is credited with identifying the plant in the 1830s, legend has it that she was taught about the plant's properties by a Shawnee woman.[3][4] The Shawnee woman's name is lost to history, but she and her people would have had deep knowledge of the herbs and plants in the area.
The plants are also poisonous to horses, goats, and sheep. Signs of poisoning in these animals include depression and lethargy, hind feet placed close together (horses, goats, cattle) or held far apart (sheep), nasal discharge, excessive salivation, arched body posture, and rapid or difficult breathing.
