Overview 1. What this course is really about and why I’m teaching it 2. How the course is organized 3. Stuff you’ll need for the course and the next lecture Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 4
Big Picture This course is really designed to teach the wonder and excitement of the universe around us • I want it to be understandable • By the end of the course, I want you to be able to COMMUNICATE the understanding, the excitement and the evidence to others Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 5
The Story • I think in terms of crime stories and the evidence for them The Scientific Case of How the Universe Came to be the Way is Now • We have a good degree of confidence in this story Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 6
Some of the Questions • How did the Universe come to exist? • A Big Bang occurred… then what? • How did we get from a Big Bang ~14 billion years ago to the Universe we have today? • What are black holes REALLY? • What are dark matter and dark energy? • Is the Universe REALLY expanding? Will it contract again and we’ll all die? Introduction • Should I be worried? Topic 1: Introduction Big Bang, Black Holes, No Math 7
Questions and Evidence • These are important questions for all for humankind • Everyone should know about (some of) these questions and (some of) what we know about the answers • You should also know something about the evidence Introduction Big Bang, Black Holes, No Math Topic 1: Introduction 8
Communicating the Excitement • A great deal of the understanding can be had WITHOUT the math – You can enjoy music without being a musician or a composer • As future leaders I want you to be able to go out into the world and effectively teach your senators, friends, co-workers, etc. why this stuff is exciting and important Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 9
Back to the Course This course is designed to teach you about the Big Bang, Black Holes, Dark Matter, Dark Energy, and other stuff, and to do it without the Math Next talk about HOW we’ll do it… Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 10
Being a Detective • Want you to use evidence to make decisions like a detective (Sherlock, Elementary, Criminal Minds, CSI, NCIS, Bones, Law & Order, others like Scooby-Doo…). For example: – Don’t need you know HOW to do DNA tests – Do need you to understand that DNA tests (using blood from the scene of the crime) can tell us whose blood it is and provides evidence they were there • Can we put together evidence that would Introduction Big convince Bang, Black a jury to convict? 11 Holes, No Math Topic 1: Introduction
What’s the Evidence? • What is the evidence that the Big Bang actually occurred? • What is the evidence that supports our understanding of the “history” of the Universe from the beginning until today? • What is the evidence for little things we can’t see directly with our own eyes? • Atoms, protons and electrons • Dark Matter • Black Holes Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 12
Course Content These are REALLY big questions • We want to know what we observe in the universe – Big and Small • To do this we need to understand some of the most important ideas in science – Quantum Mechanics – General Relativity – Others Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 13
Don’t worry • Don’t worry… we aren’t going to do ALL of physics in a semester • We aren’t going to ask you to calculate anything • What we want is for you to understand, and re-tell, the story and explain some of the evidence Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 14
Ok… worry a little • This course will make you question what you know about nature and history. If you are uncomfortable with that, you may not like this course • This course is harder than it looks. If you are looking for an “Easy A”, you should drop before it counts against you • If you are looking for a course where you will can get an A if you put in the work, then this could be a good fit Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 15

Prep for Lecture 2 Pop Quiz The in-class quiz at the beginning of the next class on will contain at least two of the following questions: • Why are you taking this class? • What do you most want to know about? – Be prepared to answer these two honestly (there are no right answers, and don’t tell me what you think I want to hear) • Are you taking ASTR/PHYS 119? Why/Why not? Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 23
Before we start… • Get comfortable… we will be using the full lecture time today • Studies show that the students who sit up front get the best grades – Studies also explain WHY – http: //tobackgroup. physics. tamu. edu/toback/Teaching. Article/Perkins. Wieman_P T. pdf • As the semester moves on we will stop allowing people to sit in the back rows • We will not be allowing laptops and cell Introduction Big phones Bang, Black without permission 24 Holes, No Math Topic 1: Introduction
Next Time… • Start with an in-class written quiz and in-class i. Clicker quiz • Talk more about – End-of-Chapter Quizzes in e. Campus – Grades • Lecture is on Chapter 2 • The Very Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 25
Aside before we continue • I will admit I have a bone to pick… I think there is WAY too much ignorance about science and too much science phobia • Some of the many problems: 1. Physics taught for people to USE rather than enjoy (physicists/engineers in training) 2. Learning to DO physics requires math, and lots of it, which makes it un-fun for many people 3. Often taught by people who have forgotten what it was like to not understand Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 26
Class Time • We meet from 5: 45 PM to 7: 00 PM • Will use the full time period • I expect you to be on time, and prepared for class by being caught up with all the assignments Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 27
Coming to Class • Need you to be proactive DURING class!! Get into it and have fun • If you need sugar or caffeine go for it… just do it quietly – Candy/Soda machine just outside the door at the top of the steps • Laptops will only be allowed in the first 5 rows, and with explicit permission – They are too distracting Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 28
Class Time • Lecture will be a time where you and I interact by asking and answering each others questions • You will need prepare BEFORE lecture – Do the reading assignments – Write down, and turn in online, questions on the reading • “Pre-Lecture Reading Questions” – Be ready to be answer questions in class using a clicker • If you don’t understand something, ask a question in class! Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 29
Course Work You will: • Read about the Big Bang and Black Holes in the books • Ask and discuss questions before, during and after class • Answer some questions in paper format, and learn to be a critic of excellent writing • Take quizzes online about the material Big Bang, Black Holes, No Math Introduction Topic 1: Introduction 30

A single line for each rubric question is helpful. Often the reason you picked No is the most helpful – The feedback from e. Campus itself (if any) that the quiz gives you when it tells you go didn't get the question right. You can find that under 'My Grades'. Look for the quiz and click on it. Then click on the score (number). The attempt result will open and show all the information, including your answers and feedback. • With that information we can usually figure out what is causing you to struggle (and will usually just give you two more attempts). • Then again, maybe you are correct and we need to fix it in e.

Example Warm-up Help Email to 109 help@physics. tamu. edu Hello, I’ve run out of attempts of Requirements Quiz 2, and would like to request more. Here is the question I’m struggling with Question 7 "Which assignments require you to get all the parts exactly correct in order to get a passing score? (select all that apply). Hint: Some assignments require you to get all the parts exactly correct to get a Passing grade. Some assignments require you to get a minimum score (<100%) in order to get a Passing grade. While it's true that when you get a Pass for an assignment we will give 100% of the *points*, but that isn't the same as getting all the parts of the assignment exactly correct. " – Warm-up and requirements quizzes - Yes. All of these require getting every question correct. – An End Of Chapter Quiz for every chapter (except Chapter 1) - Yes. All of these require getting every question correct. – PLRQ Boot Camp quizzes - Yes. All of these require getting every question correct. – PLRQ Unit 1 assignment in CPR - No. While it's true we have to pass this assignment, we don't have to get all the parts exactly correct. – Paper 1 assignment in CPR - No. This isn't pass/fail. We don't need to get it perfect. – Astronomy Misconception Survey (AMS) - No. This isn't pass/fail. We don't need to get it perfect.

Example Request for Additional PLRQ Attempts Email to 109 help@physics. tamu. edu • PLRQ Quiz - Hard "Are cosmological principles and religion totally incompatible, or is it possible to integrate the two? " #1 #2 #3 #4 #5 - Yes, they have read the material No, it is not exactly relevant to the topic at hand Yes, the question is clear Yes, reflects critical thinking Yes, it asks for info beyond the reading Response Feedback: This question has some parts which make it hard to assess. It clearly is about the reading (specifically the part about the cosmology), and it's clearly stated (we can understand what it is asking). It certainly is interesting (many people buy lots of books about the topic), but it's not clear it is an interesting *science* question. Even though it is borderline, we decide to be generous and give a Yes for Rubric 4. Rubric 5, on the other hand, concerns whether the question is asking about "science beyond what is in the reading. " This is not asking about the science beyond the reading. Rather it is about the compatibility between cosmology and religion. We give it a No for Rubric 5.
