Math and Science?

Math and science. What EXACTLY is math and science?
Theories? Microbiology? Material science?
Why is it that we are so obsessed about studying stuff that we can barely see and barely use?
Why isn't psychology a stream of science?
Is it not as important to know the effects of uniform has on people's creativity as it is to invent pills that can help us remember better?
Is it not as important to learn about ourselves and our minds as it it to learn about the functions of different organs in our bodies?
Is it not as important to understand common sense?
Why is it that the "hard-core" "mainstream" math and science rejects common sense, the very basis of life?
Why do they insist on generating a whole bunch of information and analysis that is only of interest to the academics?
Why do we have to feign interest in other animals when we, as egotistical creatures, are more interested in ourselves and our minds (proven by the fact that we are obsessed about our intelligence and are always wondering about the source of knowledge and consciousness)?
Science? Bleh!
