And they feed fish products to cows and chickens. The mercury should be there, too.

its all big alchemy immortals trying to keep mercury's benefits under wraps

Visit any old city in the UK (York and Edinburgh for example) and a lot of passages between streets have steps with uneven heights.

When you're expecting it, its fine, you take extra care. But when its a modern building and they've fucked it up you really notice

I know of a few cases in religious buildings where stairs were designed to have a mystical effect. In Angkor Wat, for example, the stairs have a steep and tall tread pattern. Commoners weren't used to them so they'd be exhausted, but the local monks were used to them so they could ascend and descend with ease.

My house is over 100 years old and all the damn stairs are different.

I guess in China the number is smaller because the average people are smaller. Otherwise it is universal. It has been found out, not made up arbitrarily.

But when it stopschuggingalong it's a glorious mess.

Despite the many issues that it can cause, that is an important feature of BGP. Since network connections can be asymmetrical, and outbound and inbound connections can have different requirements, the best (or most adequate) route from A to B might not be the best route from B to A.

Don't forget zipper merging. I lived in an area where hundreds of hours spent commuting allowed me to observe the inability to merge was the primary driver of freeway congestion.

Which this actually isn't a straight example of, exactly. Jevon's paradox says more and better roads will mean more cars operating, not less. That happens, but in this case the increase is so great, that it leads to the same level of congestion on the roads all over again.

The wiki uses the example of coal. Better boilers and engines increased the use of coal, but it's fair to say industrial Europe had better coal powered equipment afterwards, not the same or worse. (Although, to be fair, congestion is only one metric of traffic performance)

IIRC the trend is observed over longer periods, where it feeds into people's decisions about whether to have a car or second car, and how far to commute. And even then, congestion and travel time are two different things - an extra lane probably makes no difference, but a new route or higher speed limit will get you there faster regardless.

The number of car-hours per person per year isn't even close to fixed over the long run. The trend is basically that in the past, people might have carpooled, taken a bus or even hitchhiked, and usually lived close to their job. If the roads get better, they drive more.

Well, played, my friend, well played.

Got to make sure I'm providing what OP wants.

Aggregates with a lot of unstable silica like strained quartz can cause the creation of silica gel when exposed to cement. The aggregate supplier should be the one running tests to prove they don't have reactive silica.

Other tests include air entrainment and the slump test. The concrete mix requirements should be chosen by the engineer or architect.

That reminds me, I need to get a new one for my hot water tank. I've lived here 6 years, you're supposed to change them around 5.

But French has a number problem four twenty ten nine times worse.

Ah yes, one foot four hundred inches. /s

oh interesting, this is the first time that i see this. but it kinda makes sense, thanks.

Even cracked raw eggs can be volatile if you don't scramble them.

An asphalt fact, rather. Asphalt facts have lower modulus, so they are more adaptable to the point of the conversation.

The workers at the jobsite are going to have an issue when they've showed up to pour a slab and your cement order arrives.

It's like expecting dough and receiving a bag of flour.

Cement is only the binding agent that makes it harden. Concrete is made from sand/gravel, water and cement (+ additives).

He's obviously talking about the book series by Christopher Paolini.
