I'm really big into science.  It's my favorite of all the STEM fields, although math is a close second.
what is STEM fields? I have never heard about it
STEM is an acronym for Science, Technology, Engineering, and Math.  Back in the day, it used to be called METS.
I see. I love math, at college I studied calculus, and I loved it
I never made it past calculus in high school.  I especially liked the parts that dealt with calculations of volumes of rotating graphs and areas under a curve.
Well, when you are studying calculus is the same thing, you want to know about the areas too
I wish I had spend more time with differential calculus, because a a pilot now, there's a lot of math that has to do with rates of change.
why did not you spend more time with differential calculus?
Calculus
Calculus, originally called infinitesimal calculus or "the calculus of infinitesimals", is the mathematical study of continuous change, in the same way that geometry is the study of shape and algebra is the study of generalizations of arithmetic operations.
It has two major branches, differential calculus and integral calculus. Differential calculus concerns instantaneous rates of change and the slopes of curves. Integral calculus concerns accumulation of quantities and the areas under and between curves. These two branches are related to each other by the fundamental theorem of calculus
possibilities within the arts and a pressuring need for a strong work force within the STEM fields (Science, Technology, Engineering and Math) research show that arts education is crucial in children’s learning process and development. In 2013 a congressional resolution sought to include "A" for Art in the STEM acronym, changing it to STEAM. Studies show that children exposed to arts education throughout childhood through primary, secondary and tertiary school show greater scores on academic achievements as well as greater social, cultural, emotional and cognitive development.
