Print Settings Supports Yes Overview and Background Lesson Plan and Activity Spherical representation of cosmic microwave background radiation (CMBR) Science teachers can use this object to teach about the CMBR, particularly suited for conveying it to visually impaired individuals. This radiation is the oldest light in the universe and was discovered accidentally by American astronomers Arno Penzias and Robert Wilson in 1964 Alternatively, math teachers may use this object to demonstrate mapping of 2D and 3D surfaces The CMBR is typically visualized as a two-dimensional projection, specifically the Mollweide projection seen here: http://map.gsfc.nasa.gov/media/121238/ilc_9yr_moll4096.png. Teachers can note that the Mollweide projection is severely distorted near the poles This 3D object exhibits a more accurate, spherical representation of the CMBR Comparing certain features in the 2D and 3D representations will highlight the effects of mapping algorithms References Usage These files are released under the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International license Please reference Clements, Sato, and Portela Fonseca 2016 whenever these files are used Commercial use of these files or derived works is not permitted The rights to commercial use are reserved by originators D L Clements, S Sato, and A Portela Fonseca Published October 28, 2016.
