Iran has been publicly shouting about their plans to close the straits in the event of war for at LEAST 25 years. That’s just as long as I can remember it.

Napoleon I slaughtered millions of people, and led millions more into deaths of disease, hunger, and deprivation.

His reign was catastrophic for his enemies - and for his people.

And we are seeing a repeat of history because humanity failed to internalize reflexive disgust at the narcissist.

The closest analogue in history that I can find to Trump is Napoleon I.

Bonaparte was a narcissist, a tyrant, and leveraged luck into an aura of invulnerability. He was charismatic and savvy, but ultimately just a thug and endlessly hungry for more.

Like Trump, he started many pointless ego wars.

A big drawback to the Ross is that the whole first year after surgery is challenging: strict BP control, lots of naproxen, sloooooow cardiac rehab.

Mechanical valves it’s not unreasonable to think I’d be doing marathons this time next year.

My surgical center has a perioperative mortality rate under 1%.

Their perioperative stroke rate is under 1%.

And I’m in the lowest risk in all categories.

So, unless my pulmonary valve is unsuitable for reimplantation, I think the Ross is the way to go. And BB agrees.

The Ross Procedure provides restored expected lifespan compared to people without heart valve issues.

That’s appealing - even if I have to undergo another procedure in 20-25 years. (Or sooner if I’m unlucky).

The Ross also offers a 65-80% chance of no further operations for 25 years. And because of my anatomy, I’m in the lower probability group.

I have stenosis. That’s better for this than regurgitation.

First, it allows me to stay off blood thinners, which is a good goal. They’re somewhat difficult to manage - and the risk of stroke and clot result in an expected 2-4 years of lifespan reduction.

So: heading into my CT scan tomorrow, which will definitively determine our approach to my aortic valve replacement, I am leaning heavily toward the Ross Procedure.

It’s a major surgery - beyond an isolated valve replacement. But I have a good surgeon and it has distinct advantages.

No today is just talk therapy in preparation. Tomorrow is CT scan and then later I have a cardiac cath study.

Lots of work goes in to preparing for this.

Of course. I suspect that it may be a bit from column a, a bit from column b.

Oil commodity is an especially complex system that I’ve never really dug into - though it’s fascinating.

I wish the secretary of energy actually had though.

And really - I don’t want to be going through caffeine withdrawal while also recovering from heart surgery.

So I’m going way down on coffee. Because I don’t think I’ll get it in the ICU, and supposedly quitting can lower your BP by a few points.

I’m right at the BP target for my surgeons (usually 115/72). But every point counts.

I wonder how the admin will spin “we took OUT race as a factor” to impugn a clear good because in their minds it will deprive white people of kidneys.

In the Comb, circles are just weeeird, unless they’re degenerate. And again, I’m not sure how to define a circumference. Or a boundary at all for that matter.

Also, in the taxicab topology, it's pretty clear that Pi=4.

Assuming the circumference exists. The radius does: the maximal chord from any two points in the circle has length 1. The circumference is unclear: every point in the space is on the circle. I'm not sure how to calculate a circumference there. Is it infinite? is it 1?

But if you can, will the ratio of the circumference to the radius always be a fixed constant in every topology? It will clearly not always be Pi. Easy counterexample in the trivial topology where d(a,b)=1 for all a,b.

OK Math nerds. Are there analogs of Pi in other topologies? There are, obviously, circles. Regardless of topology you can define a circle as the set of all points equidistant from an origin point. Once you have a circle, you may or may not be able to define a circumference and a radius.
