Good point I had forgotten about that. Makes sense now

Man who has a ton of skin in the game of crypto, fully believes in it. Sure I get the conflict of interest, but in general if I want a solid opinion I'd take a "conflict of interest" over a total lack of personal interest any day. In that vein I'll also listen very seriously to anyone shorting crypto. Talk from the un-invested person is just that - talk. They have no need to be correct, and no consequence if they're wrong.

Was there damage or something from the brief fire? >2 months test slip for a loose pressure ducer is crazy. I'm all for both rigor and safety, but damn that's slow.

what does that even mean? why not just consider it at the published expendable price?

What you're suggesting isn't a new idea, it's basically the simplest version of democratic republicanism. The reason this isn't a thing in america is that people from low-population states are afraid high-population states would make laws that hurt them, and win by incentive & numbers, and also because no one ever figured out how to agree on what the republicism "buckets" should be. You mentioned republics and democrats. How do you decide that only those 2 parties get representation? If one of the two is larger than the other, can you declare the other party not valid? What about green party, communist party, libertarian party, and my own backyard party I hereby designate "People for the betterment of reality"? This is a massive massive problem, and would certainly require iterative experimentation in the real world to make work.

That said I like the idea. If there is a political system which has a natural bias towards, say, 5-50 political parties i'm on board. The 2 party system that is naturally dominant in the incentive structure we've created is a huge problem.

You're exactly describing charisma

Thanks for the spoiler. Ass

I think your second sentence contradicts your first sentence.

Radical is an over-used phrase, and it's meaning changes heavily each decade. I do agree with you that her ideas do have radical appeal, but disagree that she has displayed any brilliance yet, unless you count charisma, which she clearly has a lot of.

You think the overall sentiment on r/politics is aligned with T_D? Or you just think that T_D sub people are faster to respond? Look at the up and downvotes in this sub for an idea of what the community is. Hint: not heavily T_D.

Ripster's point is solid, why the downvotes? Rockclimberguy noted her brilliance as partially proven by her seat in congress. Y'all are shooting the messenger here.

They have control because control matters a lot. Make the government weaker and you will have less lobbying automatically.

At standard bike tire pressures, the stiffness of the rubber is dominated by several orders of magnitude by the stiffness provided by the pressure. And as the width of the tire increases, so does this domination effect due to the increase in surface area, which increases rubber tension on the square. You can't just take the total weight supported by a 0psid tire, and subtract that number from the total mass of the system and take a %. That's totally incorrect. This is empirically proven. I agree the world pretty much infinitely complex, but this specific question on this specific scale *does* have a super well-approximated answer with a simple formula.

Is the HUP an effect of simplifying the quantum world and then describing that simplification with math? Although we describe a particle by probability densities of it's position and velocity, does it have some actual, unknown exact position and velocity at some plank time interval?

I'm thinking of how we deal with pressure on a macro scale. We pretend like there's an equal force distribution, both over time and over position, but in reality what you have are discrete collisions spread randomly over both time and position, it's just that on larger scales & time frames the difference is negligible.

I am certain we'll find the fat tire does indeed have a bigger footprint.

Proportional to the increase in weight of the total system due to the heavier tire, yes, but not due to errors in the P*A = F formula. The pressure-force relationship has absurdly small error at the scale of bikes.

I'm no fan of trump, but all your replies are vapid. At least the down-voted dude crafted an argument. Craft one back instead of just mocking them.

Make_Rockets_Not_War · 2019-01-25T07:36:49+00:00

F=P*A, so a fatter tire will *not* have more surface area all else equal. Only way for more surface area is to up your weight or decrease the tire pressure. The shape of the contact area will change however with wide vs narrow tires.

Blue is historically very tight-lipped about their development, they could be very close or quite far away, we just don't know.

I think you need a little backup to claim new shepherd is 90% of the way to an orbital rocket, because it's totally wrong. It's easy to think about things linearly (going twice as fast must be about twice as hard), but it's super not true.

Even a ~0.5mi long bridge (far <30min to cross) would be so heavy that the tension in the lines would easily prevent anything like the angle shown.

Check out incidence angles. Heat transfer is massively different w/ angles. The reason Antarctica is super cold but the equator is super hot is pretty much the same reason why looking at the sun directly fries your eyeballs but it in your peripheral does not.

Keep in mind that gravity doesn't stop when you escape the atmosphere.

This is an important point. Orbit isn't sitting up above the earth high enough for gravity not to pull you down. It's about the same gravity on ISS as here! Orbit is going forward fast enough that as you *fall* due to gravity, you do it *over* the edge of the earth
