Odyssey Virtual January 23, January 23, MondayBrought to you by Odyssey   Jan. 23, 2023 – Feb. 27, 2023 (6 sessions) Mondays, 6:30 PM - 8:00 PM ET   Course Description Over the centuries, there are major themes in the history of art that continue to appear and reappear in different ways and styles. This course addresses FOUR such major themes, namely: PORTRAITURE, LANDSCAPE, RELIGIOUS PICTURES, and the HUMAN FIGURE. Two sessions will be devoted to each theme, exploring the development of each and studying different artists in the process. It is an enriching way of understanding stylistic differences and unique artistic expressions through the ages. Participants will be able to understand the development of Portraits, landscapes, Holy Pictures, and the Figure through the ages, to study a wide variety of artists from different periods in western art, as well as to appreciate the art produced and how each piece reflects the times when it was produced.   Tuition Remission and Refund Policies Full-time JHU faculty/staff, their spouses or same-sex domestic partners, JHU retirees, and their spouses or same-sex domestic partners are eligible for tuition remission. The tuition remission form is required. All tuition remission forms and details on eligibility can be found here and should be returned to odyssey@jhu.edu.  After registration, tuition remission eligibility will be confirmed by the Odyssey registrar. If eligibility cannot be confirmed, you will be required to pay full tuition for the course. Under the terms of the University’s remission program, Hopkins employees must withdraw in writing at least five working days before the first class to receive a 100% refund. No partial refunds are given to JHU employees and affiliates.   Please visit the registration and policies page for more information. cassarodysseyspring23

Odyssey Virtual January 24, January 24, TuesdayBrought to you by Odyssey   Jan. 24, 2023 – Feb. 21, 2023 (5 sessions)   Tuesdays, 6:00 PM - 8:00 PM ET   Course Description: This is a five-week long course that will provide a fundamental understanding of how human eyes perceive different colors. Through online simulations and PowerPoint presentations, participants will learn about primary and secondary colors, the roles played by the eye and brain in interpreting the colors of an object, and the sensitivity of human eyes to the different spectral colors emitted by the Sun. They will gain an understanding of why humans prefer some colors over others, Weekly tasks, such as online assignments, activities, and a short write-up will be assigned. There is no pre-requisite for this course.   Johns Hopkins Tuition Remission Policies Current and retired full-time Johns Hopkins faculty and staff, as well as their spouses or domestic partners, are eligible for tuition remission.

Odyssey Virtual January 27, January 27, FridayBrought to you by Odyssey Jan 27, 2023 (1 session) Friday, 6PM- 8PM   Course Description: This is an evening lecture to highlight the debate centered around the precise value of the expansion rate of the Universe. This controversy is known as Hubble Tension. The fundamental features of the Universe, such as its age and observable size are characterized by an important parameter known as Hubble parameter, H0. In order to understand the past and future evolution of the universe, it is very important to know an accurate value of this parameter. Historically, this value has been measured by observing distant galaxies and calculating how quickly they are receding from observers. Collecting a large amount of such data from Hubble telescope can yield an accurate estimate for H0. Alternatively, scientists can extract the value of Hubble parameter from the Cosmic Microwave Background (CMB) data. The CMB is the very first light in the early universe produced around 300,000 years after the Big Bang. At that time the universe was cool enough for matter to form, and for light to propagate freely through the universe. CMB data from Planck spacecraft can be used to determine the value of Hubble parameter in the early universe, and then infer the present value of the parameter using Cold Dark Matter Model. Hubble Tension arises because two values of the Hubble parameter obtained by the above two different methods do not coincide. There is a 9% discrepancy between these two values, The Cepheid-Supernovae Distance ladder measures a value (H0= 73.5±1.4 km/s/MPc) in the present-day universe on galaxy receding, and a value (H0= 67.4±0.5 km/s/MPc) inferred from the early Universe using the CMB Planck data, it is not clear if this discrepancy in values arises due to an inaccurate measurements or if there is a fundamental issue in the model, demanding for new physics to be incorporated in the model. The present talk will discuss various ideas proposed to resolve Hubble Tension.   Johns Hopkins Tuition Remission Policies  Current and retired full-time Johns Hopkins faculty and staff, as well as their spouses or domestic partners, are eligible for tuition remission.

Odyssey Virtual February 07, February 7, TuesdayBrought to you by Odyssey  Feb. 7, 2023 - March 7, 2023 (5 sessions) Tuesdays, 6:30pm-8:30pm   Course Description:  An alternative to a writing workshop where participants critique each other’s writing, this course is a practicum focusing on sentence-level improvement. Using a method the co-instructors developed called “the sentence-composing approach,” participants practice sentence strategies used by authors ranging from J. R. R. Tolkien to J. K. Rowling. In building better sentences, participants learn to do what successful authors do, and will leave each session with sentence-building tools applicable to almost any kind of writing--academic, business, literary, or personal.     Johns Hopkins Tuition Remission Policies Current and retired full-time Johns Hopkins faculty and staff, as well as their spouses or domestic partners, are eligible for tuition remission.
