We are excited to host 176-th and 177-th Carnival of Mathematicsin a single blog post for December 2019 and January 2020. And perhaps this is happening for the first time in the history of Carnival of Mathematics.Carnival of Mathematicsis a monthly blogging round up that is organised byThe Aperiodical. We choose to host Carnivals in December because 22nd of December is celebrated as National Mathematics Day of India. Indian legendary Mathematician Srinivasa Ramanujan was born on 22nd December 1887. In order to recognize his immense contribution towards Mathematics the Government of India has declared Ramanujan's birthday to be celebrated every year as the National Mathematics Day of India.
The following posts together makes the 176-th and 177-th Carnival.
