*imply

Sure. By even the density/mechanical properites of armor will affect its usefulness. Beyond simple thickness.

I mean this does have a practical application, I think. The relative masses of moons to planets does imply the moons ability to sweep junk out of the way before it hits the planet.

No

neptune , to Ask Science in Have we been able to reproduce the conditions to bend rocks? (Even if in a lab.)

Creep is the mechanism you refer to. Yes absolutely scientists can replicate creep in the lab. You too can at home by leaving butter on the counter and watching it bend under its own weight at room temperature after a few days.

At about 1/2 or 2/3 of the melting temp and above, materials start to behave kind of funny.

neptune , to Ask Science in What's the equivalent of physics constants for social studies?

I think gravity and light work the same on psych majors as it does physics and engineering students…

I kid.

So in biology I know e the Euler number is important. It is used in growth equations (from finance to physics as well).

Statistics is fucking huge in every field. That is how you measure uncertainty. Bell curves and the Five Numbers and all that stuff is how you analysis thousands of widgets coming off an assembly line, or measurements in the social sciences field.

neptune , to Ask Science in Could non-Newtonian fluids be used in the future as a kind of percussive ear protection?

We already have computers that can determine which sounds to cancel out. That’s pretty cool.

Sound isn’t going to be like a bullet or an electrical storm hitting the grid. I don’t think you can just make a material that blocks out sound when it reaches a certain level and allow it below the threshold. Definitely an interesting theory but I am not sure how it would be designed.

neptune , to Ask Science in How dark is Mars compared to Earth in a very practical sense?

Mars is 1.52 AU from the sun, or 1.52x further than Earth, so the inverse square law says 43% less sun power. But the atmosphere is thinner and a different composition.

To know how the human eye actually operates on Mars, one would have to get a human eye to Mars.

neptune , to Ask Science in [Mycology] Are yeasts analogous to each other, to the point they can be used in food interchangeably?

Yes, wild yeast and spontaneous fermentation are things in the beer and wine world. Yes her beer is possible. Also it will be possibly very bad. Or fine.

You could totally make a sourdough by rubbing your butt cheeks in the starter every day and I don’t think your friends would notice.

Its funny, because 200 years ago there were no commercial good products. To make beer you basically had to let it sit out for a couple days until enough wild yeast colonized your food. This is also true of kimchi, saurkraut and a bunch of other ancient foods.

neptune , to U.S. News in Poll: US Public Support for Israel Wanes as 68 Percent Call for Ceasefire

Unfortunately gerrymandering and the electoral college probably means we need to pump those numbers up. Look at how a million Cubans in Florida have exerted sway on foreign policy for decades.

Regardless, the US isn’t actually fighting here. Sure, we can pressure netanyahu.

neptune , to Ask Science in How can we define a robust metric for "most discontinuous country" and then rank all states according to it?

Maybe we look at the ratio of country perimeter to area? Counting the number of exclaves could also be a factor. And maybe a ratio of the distance to cover all the exclaves divided by their area?

So if a country were a perfect circle it’s perimeter to area ratio would be 2/r, it has zero exclaves and then it’s width would be the diameter.

If a country were two perfect circles of the same diameter, separated by a distance of the same diameter, it’s area ratio would be 2/r, exclaves would be one, and it’s width would be three times it’s diameter.

So now you can imagine a country like Chile, modeled as a really skinny rectangle, has a pretty large perimeter to area ratio, no exclaves, and a width roughly the length of the rectangle.

I guess you’d have to decide if archipelago nations are measured as the geometry of the sea they own, or as discrete islands.

neptune , to Ask Science in How could SI units be derived from scratch without the use of modern technology?

What’s the point of recreating our arbitrary system? It just has to be useful and universal

This book was interesting.

Are you asking about how you reinvent the exact same meter? Well that won’t happen. Our units were arbitrary, useful, widely adopted, and then rigorously defined.

The book walks you through it all. You can don’t need to redo civilization exactly the same (the author even suggests some very important things to invent differently, especially in better orders)

I like affirmative action now - Republicans, probably

It turns out that capitalism literally monetizes everything and not having marketable skills can get in the way of your mental and physical well being.
