45 minutos horas de clase por semanaTarea
1 hora por semana. Each week, I will provide a workbook for the topic we will be discussing. The workbook will be a place for students to take notes and write down equations. It will also include application questions for us to work on together. I provide extra questions for students to do on their own after class, and the answers will be posted each Friday.Experiencia de clase
Math is the language of science, and with it, astronomers can describe many aspects of how the Universe functions. In this ongoing class, students will get to apply math skills to various astronomical questions such as how distances are calculated, how to use ratios to find sizes of geographical features of other planets and moons, and how we can calculate travel times and communication times to the planets in the Solar System. PREREQUISITES: This is an intermediate to advanced class. Students are encouraged to bring a calculator to class. However, they should also have a solid foundation in multiplication, division, and algebra because we will use these skills often to manipulate of equations and solve for variables. While geometry, angles, and some trigonometric functions will be discussed and utilized, it will be at a basic level. Each week, students will be guided through the mathematical steps astronomers use and will gain an appreciation for their practical value. Classes are not built upon previous material and students are welcome to join at any time. For each class, students will be provided with a worksheet to follow along with during class. **Some questions on the worksheet will be left for students to get additional practice outside of class.** The class schedule is a follows: Topic 1: Distances (Tuesday, March 26) -Scientific notation -Units of measurements used in astronomy and conversion factors -Scaling Topic 2: Angles (Tuesday, April 1) -Earth’s tilt vs. other planets’ tilts -The Moon’s phases **No Class April 9** Topic 3: Scales and Ratios (Tuesday, April 16) -Find sizes of lunar craters and maria -Find height of ejected material -Using significant figures and taking averages Topic 4: Mass and Weight (Tuesday, April 23) -Calculating your weight on other worlds -Algebraic manipulation to isolate a variable **No Class April 30** Topic 5: Time and Stellar Location (Tuesday, May 7) -Earth time vs. other planet’s time -Converting to military time -How to calculate a star's rise time Topic 6: Apparent Magnitude: Observations and Calculating Δm (Tuesday, May 14) -History of the magnitude system -How modern astronomers use apparent magnitude -Negative numbers Topic 7: Apparent Magnitude: Brightness and Big Batch Processing (Tuesday, May 21) -Negative numbers -Logarithmic functions -Using an astronomical database -How to use a spreadsheet for large data batches Topic 8: Absolute Magnitude (Reading a Star Chart and Calculating) (Tuesday, May 28) -How to use a star chart to determine magnitudes -Apparent magnitude vs Absolute magnitude -Negative numbers -Logarithmic functions -Using an astronomical database -How to use a spreadsheet for large data batches -How to calculate percentage error in your measurements Topic 9: Geometry in the Solar System: Inferior Planets (Tuesday, June 4) -Inferior vs. superior planets -Diagramming maximum elongation -Copernican method to find distance to inferior planets (using geometric functions) **No Class June 11** Topic 10: Geometry in the Solar System: Superior Planets (Tuesday, June 18) -Inferior vs. superior planets -Diagramming opposition, conjunction, and quadrature -Copernican method to find distance to inferior planets (using geometric functions) Topic 11: Kepler’s 1st Law (Tuesday, June 25) -Ellipses -Focal point and semi-major axis -Eccentricity Topic 12: Kepler’s 2nd and 3rd Laws (Tuesday, July 2) -Proportions -Graphing **No Class July 9 and July 16** Topic 13: Newton Extends on Kepler's 3rd Law of Motion (Tuesday, July 23) -Algebraic manipulation of equations -Calculating masses Topic 14: Orbital Velocities (Tuesday, July 30) -Recognize forces that keep bodies (like satellites) in motion -Become familiar with the orbital velocity formulas -Calculate the needed velocity for various situations Topic 15: Escape Velocities (Tuesday, August 6) -Recognize forces that keep bodies (like satellites) in motion -Become familiar with the escape velocity formulas -Calculate the needed velocity for various situations Topic 16: Travel Times in the Solar System (Tuesday, August 13) -How spacecraft travel from Earth to other bodies in the Solar System -How long communication takes from the spacecraft back to Earth **No Class August 20** Topic 17: Black Holes: Schwarzchild Radius and Tidal Forces (Tuesday, August 27) -Calculating constraints for non-rotating black holes -Comparison of strength and size between stellar mass black holes and supermassive black holes
