We are familiar with Conventional Wisdom.

We could and should try something unconventional.

#### Euclid

- Euclid proposed five Postulates, which form the foundation of Euclidean Geometry.
- Some mathematicians questioned whether the Fifth Postulate (aka Parallel Postulate) was needed.
- It gave birth to Non-Euclidean Geometry (used in Navigation).

#### Newton

- Sir Isaac Newton formulated the Laws of Motion.
- High school texts describe three Laws of Motion.
- Some questioned if two laws are sufficient.

A reasoning follows.

Force = Mass x Acceleration

If there is no Force, there can be no Acceleration.

It implies that the Velocity remains constant.

If the initial state is stationary, the object continues to be in that state.

If the object is in motion, the object continues to move with that velocity.

One law can be deduced (using First Principles) by another law.

#### Physics

- The size and the speed of the object effect the “Laws of Motion”.
- Classical Physics, which was Conventional Wisdom for its time, gave way to Modern Physics (including Quantum Mechanics).

#### Grace Murray Hopper

- Rear Admiral (One Star General) Grace Murray Hopper is a Pioneer & Prime Mover in Computers and Computing.
- She won the prestigious ACM Turing Award.
- ACM also have the Grace Murray Hopper Award for outstanding young computer scientists who had a significant contribution before the age of 30.
- She is credited with coining the term “Bug” for a computer (hardware or software) failure.
- She does not like the word, “It’s always been done that way.” She has a clock which runs in the reverse direction of conventional clocks.
