Study Notes
Liquid Crystalline Materials
- Weak interactions between molecules (e.g., van der Waals, hydrogen bonding) lead to orientational or positional order in liquid crystalline materials.
Phase Transitions
- The intermediate phase formed by some compounds between solid and liquid phases is called a mesophase.
Stimuli Sensitivity
- Liquid crystals are sensitive to thermal, mechanical, and electrical stimuli.
Self-Assembling Behavior
- The combination of self-assembling behavior and anisotropy (directional dependence of properties) makes liquid crystals extremely interesting.
Viscosity Comparison
- The anisotropy and non-crystalline structure of liquid crystals make them more viscous compared to crystalline solids.
Poisson Distribution
- The Poisson distribution expresses the probability of a number of events occurring in a fixed interval of time or space.
Poisson Distribution Applications
- The Poisson distribution can be used in scenarios where events occur independently and at a constant rate, such as:
- Counting the number of defects in a manufacturing process
- Modeling the number of calls received in a call center
Call Center Example
- The mean number of calls received during any minute is 4.
- The most likely number of calls received in the call center example is 4.
- The Poisson distribution plays an important role in predicting the probability of different numbers of calls received.
