Lecture 5 - Planetary Transits

 

 

 

Overview:

Professor Bailyn talks about student responses for a paper assignment on the controversy over Pluto. The central question is whether the popular debate is indeed a "scientific controversy." A number of scientific "fables" are discussed and a moral is associated with each: the demotion of Pluto (moral: science can be affected by culture); the discovery of 51 Peg b (morals: expect the unexpected, and look at your data); the disproof of pulsation as explanation for the Velocity Curves (moral: sometimes science works like science).

Lecture 4 - Discovering Exoplanets: Hot Jupiters 

Overview:

 

The formation of planets is discussed with a special emphasis on the bodies in the Solar System. Planetary differences between the celestial bodies in the Inner and Outer Solar System are observed. Professor Bailyn explains how the outlook of our Solar System can predict what other star systems may look like. It is demonstrated how momentum equations are applied in astronomers' search for exoplanets. Planet velocities are discussed and compared in relation to a planet's mass. Finally, the Doppler shift is introduced and students learn how it is used to measure the velocity of distant objects, such as galaxies and planets.

Lecture 3 - Our Solar System and the Pluto Problem

 

 

Overview:

 

 

Class begins with a review of the first problem set. Newton's Third Law is applied in explaining how exoplanets are found. An overview of the Solar System is given; each planet is presented individually and its special features are highlighted. Astronomy is discussed as an observational science, and the subject of how to categorize objects in the Solar System is addressed. The Pluto controversy is given special attention and both sides of the argument regarding its status are considered.

Lecture 2 - Planetary Orbits

 

 

 

Overview: 

 

Exoplanets are introduced and students learn how astronomers detect their presence as well as the challenges associated with it. Physics equations are explained as well as their importance in the context of the course. A number of problems are worked out to get students used to dealing with large numbers in calculating planetary masses, interplanetary distances, etc.

Lecture 1 - Introduction

 

 

 

Overview: 

 

 

Professor Bailyn introduces the course and discusses the course material and requirements. The three major topics that the course will cover are:

(1) exoplanets--planets around stars other than the Sun,
(2) black holes--stars whose gravitational pull is so strong that even their own light rays cannot escape, and
(3) cosmology--the study of the Universe as a whole. Class proper begins with a discussion on planetary orbits.

A brief history of astronomy is also given and its major contributors over the centuries are introduced: Ptolemy, Galileo, Copernicus, Kepler, and Newton.

1.Izinkan saya untuk berbagi pengetahuan sedikit tentang geology

Adapun daftar isinya :

• Bencana Geologi
• Mineralogi
• Geomorfologi

2. Teaching Geo-science with Visualizations: Using Images, Animations, and Models Effectively

Visualizing the Earth, its processes, and its evolution through time is a fundamental aspect of geoscience. The use of visualizations - diagrams, images, animations, maps, and more - is an essential tool in helping students to visualize the Earth and its processes (e.g., references in the recommended reading list and many others).

3.Big Questions

a.How is the global earth system changing?

• Earth is currently in a period of warming. Over the last century, Earth's average temperature rose about 1.1°F (0.6°C). In the last two decades, the rate of our world's warming accelerated and scientists predict that the globe will continue to warm over the course of the 21st century. Is this warming trend a reason for concern? After all, our world has witnessed extreme warm periods before, such as during the time of the dinosaurs. Earth has also seen numerous ice ages on roughly 11,000-year cycles for at least the last million years. So, change is perhaps the only constant in Earth's 4.5-billion-year history.

b.What are the primary forcings of the Earth system?

• The Sun is the primary forcing of Earth's climate system. Sunlight warms our world. Sunlight drives atmospheric and oceanic circulation patterns. Sunlight powers the process of photosynthesis that plants need to grow. Sunlight causes convection which carries warmth and water vapor up into the sky where clouds form and bring rain. In short, the Sun drives almost every aspect of our world's climate system and makes possible life as we know it.

c.How does the earth system respond to natural and human-induced changes?

• Climate scientists have been monitoring Earth's energy budget since the 1978 launch of NASA's Nimbus-7 satellite. That mission carried a new instrument into space called the Earth Radiation Budget Experiment (or ERBE), designed to measure all of the energy leaving through the top of Earth's atmosphere. All of the incoming sunlight minus all of the reflected sunlight and emitted heat is our world's energy budget. The second law of thermodynamics compels Earth's climate system to seek equilibrium so that, over the course of a year the amount of energy received equals the amount of energy lost to space. So typically the global energy budget is in balance.
  
  

c.What are the consequences of change in the earth system for human civilization?

• Earth's climate system has been remarkably stable over the last 20,000 years or so. Human civilization developed in that time span, and our world's average temperature warmed by about 5°C to the temperature it is today. This fact points to one of climate scientists' main concerns about global warming: the temperature is rising faster than at any other time in the history of human civilization and such rapid climate change is likely to seriously stress some populations who cannot adapt quickly enough to the changes.

 d.How will the Earth system change in the future?

• As the world consumes ever more fossil fuel energy, greenhouse gas concentrations will continue to rise and Earth's average temperature will rise with them. The Intergovernmental Panel on Climate Change (or IPCC) estimates that Earth's average surface temperature could rise between 2°C and 6°C by the end of the 21st century.
