  1. Prof Jayanne English • Vastness of the Universe: • Arithmetic, Powers of Ten, • Scales, coordinates, distances, sizes • 2. Fundamentals of how we know what we know: • Light, radiation, motion, gravity • Telescopes & detectors, resolution • Brightness Laws • 3. Cosmic Topics: • Planets – our solar system and beyond • Stars – their birth and death, exotic stars • Black holes • Galaxies – our Milky Way and beyond • Cosmology – e.g. dark matter and dark energy (things we can’t see) Phys 1810 Course Outline A SURVEY OF THE UNIVERSE. The universe is defined to be the totality of all space, time matter, and energy.

  24. Syllabus Online at http://www.physics.umanitoba.ca/~english/2010winterphys1810/ Will be updated so check regularly.

  25. Syllabus • Schedule: • Revise course date: Jan 19 • Voluntary Withdrawal Date: Mar 19 • Test dates: Jan 29 and Feb 26 • Iclicker participation marks: start Jan 11 • Grading: • 2 tests and 1 exam 70% • Iclicker participation 5% • lab and assignments 25%

  26. Syllabus Continued • Office Hours: • Monday 1pm • Discussion Group • Email to make an appointment with Prof. English and with Mr. Cameron • Labs: • Start this coming week • Meet in planetarium for 2 weeks; joint with Phys 1820 • Lab schedule will be posted in Angel

  27. Learning Philosophy Format of class: • Active, participatory class. • Interaction with each other. • Images are as important as text. • I will ask questions and wait for an answer. • Encourage thinking in class. • About 50% of material will be math. • Take notes – write down what I say. • share note-taking • University Learning Centre has workshops: http://umanitoba.ca/student/u1/lac/workshops/workshops.html

  28. Learning Philosophy • Materials: • Textbook is Astronomy Today, 6th edition Chaisson & McMillian and will be in the library. If bought new, there is a website with lots of multiple choice questions for practise. • The website for this course: • http://www.physics.umanitoba.ca/~english/2010winterphys1810/ • iclicker • will register these in class on Monday. • Non-programmable calculator, for tests and exams.

  29. Learning Philosophy • Guideline for grades: • C-C+ is roughly 60-69%  average is about 65% • B-B+ is roughly 70-79%  good to very good • A is roughly 80-89%  excellent • A+ is > 90%  EXCEPTIONAL The factor that correlates most closely with grades is attendance at lectures.

  30. Learning Philosophy Tips for improving grades. • Study Notes: • Cornell Note-taking Method Link on Phys 1830 website http://www.physics.umanitoba.ca/~english/2010winterphys1810/

  31. Learning Philosophy Tips for improving grades. 2. Study Methods: • PQRST http://www.physics.umanitoba.ca/~english/2010winterphys1810/ P = Preview Q = Questions R = Read S = State T = Turnback Before each class, read your notes from the previous class and prepare Questions. I provide a “road map” for what is coming up so you can Preview the material.

  32. Learning Philosophy 3. Spend 3 hours studying for every hour in lecture. (Princeton Guidelines.) Tips for improving grades. 4. Ways of Learning: • Quiz to determine whether you are predominantly an haptic, auditory or visual learner is under the “learning styles” link at http://www.physics.umanitoba.ca/~english/2010winterphys1810/ 5. Pneumonics, meditation, etc. 6. Visit your professor. (Email or phone to make an appointment if you can’t visit Mondays at 1pm.

  33. Scientific Method: Richard Feynman • Observation, reason, and experiment make up what we call the scientific method. • The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific “truth.”

  34. Scientific Method: Richard Feynman • Where do the laws that are to be tested come from? Experiment, itself, helps to produce these laws, in the sense that it gives us hints. But also needed is imagination to create from these hints the great generalizations - to guess at the wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we have made the right guess.

  35. Scientific Method: Gottfried Wilhelm Von Leibniz • There are 2 kinds of truths; those of reasoning and those of fact. • Truths of reasoning are necessary, and their opposite is impossible. • And those of fact are contingent, and their opposite is possible.

  36. Scientific Method Science is a truth of • reasoning • fact

  37. Scientific Method: • “Laws of Nature” are defined as general rules that describe how nature works. • Evolution from one law to another, not a revolution. E.g. Newton’s Law of Gravitation is contained in Einstein’s General Theory of Relativity.

  38. Scientific Method Discuss with your neighbours: Compare the scientific approach to understanding the cosmos with other approaches such as theological, spiritual, and astrological efforts, in attempts to estimate the probability of sentient, technological life arising elsewhere in the universe. Do you feel that the scientific attitude is basically different than the others? Why?
