Brainstorming new senses

I already have this and it's horrible.

Dancing room for you and applied problems in foreign fields

What about the fact that the best compression algorithm may be insanely expensive to run? We know the math that describes the behavior of quarks, which is to say, we can in principle generate the results of all possible experiments with quarks by solving a few equations. However doing computations with the theory is extremely expensive and it takes something like 10^15 floating point operations to compute, say, some basic properties of the proton to 1% accuracy.

I'm pretty sure cost of resurrection isn't his true rejection, his true rejection is more like 'point and laugh at weirdos'.

Also for a number of commenters in the linked thread, the true rejection seems to be, "By freezing yourself you are claiming that you deserve something no one else gets, in this case immortality."

Am I mistaken in thinking that all you'd need to do is build the centrifuge with an angled floor, so the net force experienced from gravity and (illusory) centrifugal force is straight "down" into it?

Sure, this would work in principle. But I guess it would be fantastically expensive compared to a simple building. The centrifuge would need to be really big and, unlike in 0g, would have to be powered by a big motor and supported against Mars gravity. And Mars gravity isn't that low, so it's unclear why you'd want to pay this expense.

What are your contrarian views?

A big pie, rotating in the sky, should have apparently shorter circumference than a non-rotating one, and both with the same radii.

I can't swallow this. Not because it is weird, but because it is inconsistent.

There is no inconsistency. In one case you are measuring the circumference with moving rulers, while in the other case you are measuring the circumference with stationary rulers. It's not inconsistent for these two different measurements to give different results.

What are your contrarian views?

You don't need GR for a rotating disk; you only need GR when there is gravity.

The Octopus, the Dolphin and Us: a Great Filter tale

Having dabbled a bit in evolutionary simulations, I find that, once you have unicellular organisms, the emergence of cooperation between them is only a matter of time, and from there multicellulars form and cell specialization based on division of labor begins.

I'm very curious: in what evolutionary simulations have you seen these phenomena evolve?
