Appilications of science in everyday life?

Answer 1

A question with a shorter answer would be, what parts of everyday life are not impacted by science - the answer is none.

When you wake up in the morning, your mind changes processes from "sleeping" to "awake" (neuroscience, neurobiology) as you turn your alarm off (physics, electricity). You then head to the bathroom and use the toilet (physics, public health Biology, microbiology [think of the bacteria in human waste]), brush your teeth (chemistry, human anatomy and pathology) and take a shower (sanitary biology, water cycle, physics). You get dressed (physics determines how to manage the fabric weaving machines), put on deodorant and hair products (chemistry, biology). You then enjoy some breakfast (botany, chemistry) and head out the door to school.

Within those 30 minutes, you have interacted with items developed by scientists using chemistry, physics and biology knowledge and skills. This of course does not include all the botany of the living plants outside your door (or of your houseplants), the zoology of any pets you may have (or pests - insects and rodents are covered in zoology) and the sheer volume of biology that is manifest in you (physicians study for 11 years to treat humans, and each one of them only knows a very minute fraction of the information available about the human body, which is still very incomplete).

You use science at every turn as well - basic physics says don't put metal in the microwave, biology teaches you why you shouldn't touch a hot stove, chemistry explains why your soda is about to explode after you drop the can on the floor, and the list goes on. Much of what is understood as "common sense knowledge" is simply scientific information translated into the everyday world.
