Why do we need scientific apparatuses to us understand the universe if we have such strong senses

Explanation:

To answer this question it would take pages to write, so I'll give you one example.

We need scientific apparatus because, people cannot understand anything in the universe beyond a very small are with our senses. For example, have you ever looked at the moon through a telescope, you can see almost every big crater on it, yet when you look at it with your eye, can you see anything besides a white sphere with an occasional rabbit? This is just our moon, the closest celestial object to us, Anywhere farther and you cannot see anything beyond a tiny dot in the sky without a telescope. This is one out of millions of reasons why we need scientfic apparatus to help us understand the universe.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
