1-1. 개요
고유진동수란 각 물체가 가지는 고유한 진동특성을 말하는 것으로, 만일 진동계가 고유 진동수와 동일한 진동수를 가진 외력을 주기적으로 받으면 그 진폭이 무한대로(이론적으로) 증가하게 될 것이다. 이렇게 물체가 갖는 고유 진동수와 외력의 진동수가 일치하게 되어 진폭이 증가하는
Objective
Investigate the relationship of
flow conditions and fluid velocity
Understand “Reynolds Number”
in fluid mechanics
Introduction & Background
Type of fluid flows
a) Laminar Flow : a fluid flows in parallel layers,
with no disruption between the
layers
Experiment Methodology
4.1. Objective
The objective of the experiment is to evaluate system usability when messages are in practice sent and given among strong ties via “I’m Here” location-based AR messenger service. Furthermore, it aims to explore ways for service enhancement in terms of efficient, augmentatively-realized communication.

experiment is a compound pendulum experiment. Unlike the first experiment, a rod was used instead of a string, and the theoretical and measured values obtained by thinking as a rigid body with the volume and mass of the ball were compared. The third experiment is a free vibration experiment. The experiment was conducted with a system consisting of one spring and a system in which two spring

What was the purpose
of the experiments?
To stimulate the pineal gland
with resonant vibrations.
The pineal gland? Why?
Dr. Pretorious believed the pineal
was a dormant sensory organ.
A sixth sense.
Yes, well thats not a new theory.
The philosopher Descartes
believed it was a third eye.
Its not a theory, its a fact!
Then your experiments worked.
They proved the theory.
Yes.
