Steady state

And if this thing goes over 1.0, then you get infinite queues.

and the steady state weight.

So if you remember Little's Law and all of that stuff, then this predicts the average wait time for a customer in one of these queues.

So we can compare the results from the sim to the results we might expect on average from that 470 type math.

With two servers, the effect that I'm going to show here is a little less obvious, but from 470, you'd expect the average wait time to be 0.19 minutes.

But when you actually simulate this, so these are the wait times over our customers for this queue, then we will always get a wait time of a little bit less than that.

Does anybody have a guess at why our simulated wait times will often be less than the average wait times that 470 would predict in steady state? So what's special about steady state? The system's been running for a long period of time.

What's weird about a queuing system if you start it at time zero? Is anybody going to be in the queue? No, right.

What else could explain the cosmos besides the Big Bang? Was there a bounce, a steady state, or some stranger cosmic thang?

Scurvy, pellagra, rickets, and beriberi were once common ways people died, but death by nutritional deficiency happens less now since our foods are fortified.

Why does all the dry land pile up in one place while oceans surround it in every other space?

Now, there used to be.

Before we had all this evidence for the Big Bang, there was another theory.

It was called the Steady State theory.

People saw, hey, the universe is expanding.

Um, his great contributions to astronomy actually began from spare time discussions with Thomas Gold and Herman Bondi, uh, people you may have heard of because they've also made some great contributions to physics and astronomy.

Um, and these conversations led to their collaboration and resulted in the formulation of the Steady State theory of the universe, um, which is a cosmological theory.

And, um, I'm kind of going to give a little bit of a hint of what this is as we go along.

Um, the ideas that were put forth by Bondi and Gold are considered to be more philosophical.

Um, in contrast, Hoyle suggested a more of a concrete translation of these ideas by introducing a negative pressure C field into Einstein's field equations, um, which was meant to preserve the universe's matter density as it continues to expand.

So the theory essentially opposed the hypothesis of the universe's beginning being marked with an explosion called the Big Bang, which is something you may have heard of because it is still, uh, the leading theory today, and astronomers and physicists talk a lot about this as being the start of the universe.

Um, the Steady State theory, instead of going for an explosion, proposes more of a continuously expanding universe, uh, with no clear beginning and a continuous matter creation for preservation of average- ... density of the universe.

Because as it continues to expand, um, the total matter will reduce, and we need the density to sort of be preserved.
