Human Geo 9/27 - Grids & Time Zones Pt. 1

First section of notes on Grids & Time Zones
- Geography: the study of where things are found on Earth's surface & reasons why they're there.
1. Where are people & activities found on Earth? 
2. Why are they found there?
- Map: 2d flat scale model of Earth's surface (or portion of it)
- Cartography: The art/science of mapmaking.
• Eratosthenes - drew that map thats kinda wrong
- Maps serve 2 purposes:
1. Absolute & Relative location
2. Communications tool to convey the distribution of human activities or physical features
- Absolute Location: position as expressed in degrees, minutes, and seconds of latitude (North or South of Equator) & longitude (East & West of Prime Meridian)
- Relative Location: regional position of a situation of a place relative to the position of other places.
- Latitude: a geographic coordinate that specifies the north-south position of a point on the Earth's surface. Runs parallel to the equator.
Most significant parallels (latitude):
• Arctic Circle 66º 34' (66.47º) N
• Tropic of Cancer 23º 26' (66.57º) N
• Equator 0º (N/S)
• Tropic of Capricorn 23º 26' (23.43º) S
• Antarctic Circle 66º 34' (66.57º) S

 Lines of latitude main ideas:
- Parallels
- East-West direction
- Measure distance North-South of the equator
- Cross at Prime Meridian at perfect right angles
- Get shorter toward the poles with only the Equator, the longest; the Great Circle

Western Civ 4/1 - Greek Theater

Image
There were tragedies - a play where something tragic happens. There were comedies - a play where they usually made fun of common ideas (politics). The only movie I can think of that I recently watched is The Conjuring. I think this movie would be leaning more towards tragedy. The hero of the story would be the mother, who then is too focused on her children instead of herself and gets possessed by a spirit. It wasn't that she was full of pride she was just trying to care for her children. After the possession scene, however, she tries to tell one of the "demonologists" that she was okay, so that may have been a show of pride. She eventually gains her justice because there is an exorcism at the end and the spirit is driven out of her.   This is a theater in Greece. It seems to be pretty well preserved. It is outside and a circular shape and I'm pretty sure I've read before that it's shaped like that so it can project the voices.

Western Civ 6/1 - letter to my future self

I will try to make this as least corny as I can possibly make it, since this type of thing usually is a little corny. I hope you are alive and well, we would not want to die young. Currently, in 2020, there are quite a few things happening. We are in a global pandemic with the virus Covid-19, and there is rioting and looting across the U.S. due to the Black Lives Matter movement. Coronavirus has us out of school and doing online assignments, businesses have been closed for the past 2 months and are just now opening back up (the mall still isn’t open  ). Christiana mall in Delaware was supposed to open today (June 1, 2020) but now is delayed because they don’t want to get looted like another Delaware mall. I spent multiple hours last night watching the rioting, and from what I saw and what was broadcasted on the news this morning, the cops are the reason they become violent. It was the same pattern in nearly every city, people would be peacefully protesting, the cops would show up in r
