NASA Earth, Moon & Mars Exploration Maps | Ross Beyer | Talks at Google
High-quality planetary maps and 3D terrain models have become essential for NASA to plan exploration missions and conduct science. This is particularly true for robotic missions to the Moon and Mars, where maps are used for site selection, traverse planning, and planetary science. This is

Space Archaeology: A New Frontier of Exploration | National Geographic
Space archaeologist and National Geographic Fellow Sarah Parcak hopes to discover unknown archaeological sites around the world and protect them from looting and encroachment by using satellite imagery taken from 724 kilometers (450 miles) above the Earth. Parcak is making it possible for

In this video, we introduce and discuss spectra (in the sense of homotopy theory). We explain how they generalise abelian groups. Feel free to post comments and questions at our public forum at https://www.uni-muenster.de/TopologyQA/index.php?qa=tc-lecture Homepage with further informa

[Lesson 1] QED Prerequisites Dirac Formalism Part I (redux)
(Editorial repair made in this version) This lecture is the first in a series of topics related to QED prerequisite material. I will be selecting some topics that students are often not clear about when arriving at QED. These topics cover a wide variety of material in elementary quantum m

What is a Manifold? Lesson 14: Quotient Spaces
I AM GOING TO REDO THIS VIDEO. I have made some annotations here and annotations are not visible on mobile devices. STAY TUNED. This is a long lesson about an important topological concept: quotient spaces.

Stable Homotopy Seminar, 8: The Stable Model Category of Spectra
We discuss the enrichment of spectra over spaces, and the compatibility of this enrichment with the model structure. Then we define the stable model structure by adding extra cofibrations to the levelwise model category of spectra, and restricting the weak equivalences to those maps which

Stable Homotopy Seminar, 3: The homotopy category of spectra
We discuss the Brown representability theorem, and give the Boardman-Vogt definition of the homotopy category of spectra. Examples include suspension spectra, Omega-spectra arising from cohomology theories, and Thom spectra. ~~~~~~~~~~~~~~~~======================~~~~~~~~~~~~~~~ This is
