question:
The Montana Territory was formed on April 26, 1864, when the U.S. passed the Organic Act. Schools started forming in the area before it was officially a territory as families started settling into the area. The first schools were subscription schools that typically held in the teacher's home. The first formal school on record was at Fort Owen in Bitterroot valley in 1862. The students were Indian children and the children of Fort Owen employees. The first school term started in early winter and only lasted until February 28. Classes were taught by Mr. Robinson. Another early subscription school was started by Thomas Dimsdale in Virginia City in 1863. In this school students were charged $1.75 per week. The Montana Territorial Legislative Assembly had its inaugural meeting in 1864. The first legislature authorized counties to levy taxes for schools, which set the foundations for public schooling. Madison County was the first to take advantage of the newly authorized taxes and it formed fhe first public school in Virginia City in 1886. The first school year was scheduled to begin in January 1866, but severe weather postponed its opening until March. The first school year ran through the summer and didn't end until August 17. One of the first teachers at the school was Sarah Raymond. She was a 25-year-old woman who had traveled to Virginia City via wagon train in 1865. To become a certified teacher, Raymond took a test in her home and paid a $6 fee in gold dust to obtain a teaching certificate. With the help of an assistant teacher, Mrs. Farley, Raymond was responsible for teaching 50 to 60 students each day out of the 81 students enrolled at the school. Sarah Raymond was paid at a rate of $125 per month, and Mrs. Farley was paid $75 per month. There were no textbooks used in the school. In their place was an assortment of books brought in by various emigrants. Sarah quit teaching the following year, but would later become the Madison County superintendent of schools.
answer:
When was the Montana Territory formed?


question:
Likewise, group theory helps predict the changes in physical properties that occur when a material undergoes a phase transition, for example, from a cubic to a tetrahedral crystalline form. An example is ferroelectric materials, where the change from a paraelectric to a ferroelectric state occurs at the Curie temperature and is related to a change from the high-symmetry paraelectric state to the lower symmetry ferroelectic state, accompanied by a so-called soft phonon mode, a vibrational lattice mode that goes to zero frequency at the transition.
answer:
What aids in predicting changes of physical traits?


question:
Before World War I, Tesla sought overseas investors. After the war started, Tesla lost the funding he was receiving from his patents in European countries. Eventually, he sold Wardenclyffe for $20,000 ($472,500 in today's dollars). In 1917, around the time that the Wardenclyffe Tower was demolished by Boldt to make the land a more viable real estate asset, Tesla received AIEE's highest honor, the Edison Medal.
answer:

Where did Tesla look for investors prior to WWI?
