After the bigbang, universe started expanding. It is continuing like that. What chemical reaction prompted to make water and how did it spread in the universe? What happened that water came to the earth and when did it actually come?
Sintering is carried out for ferrite materials in microwaves. I want to know the physical interaction between the molecule of the ferrite (magnetic oxide) and the microwave so that I could adjust...
