Its general mechanical background stuff
In control dynamics u have a transfer function and need to determine the Routh-Hurwitz criterion it will sometimes give u division by 0 errors so u sub in a variable and say its almost zero but not quite and continue on like nothing happened.
Eg determining the stability of a system with characteristic eq of A(s) = 3s^4+6s^3+2s^2+4s+5=0
If u do a RH array u will end up with a zero which then will give u (4*0−30)/0 so u sub in 𝜀 for 0 giving (4𝜀−30)/𝜀 and continue on. That eq obviously evaluates to negative infinity. U are essentially just saying 𝜀 is an infinity small positive number ie it is the number next to 0 on the positive side.
EDIT: If the markdown is messed up the eq should be A(s) = 3s**4+6s**3+2s**2+4s+5=0
When using ** as super notation
π=√10=√g=3=e=c*10^-8
Not a conservative but get called one a lot so we go.
I hold only 2 core beliefs and everything else is derived from those 2.
I believe in liberty and equality (of opportunity).
This via logical conclusions leads me to many an opinion that are considered conservative.
For instance abortion is murder but it is also a woman's right to get an abortion.
Equality of the unborn child to have an opportunity at life makes it murder. Liberty of the mother to not be forced to have that child is liberty. Liberty outweighs life such sentiment is summed up perfectly via.

Free speech. The only way to combat bad ideas is with better ones.
Water is evaporated which takes a lot of energy due to latent heat. Essentially its very energy expensive to boil water.
Its a failed experiment. It had no real backing and thus has no real power.
I'm in a rental so it goes straight down the drain
