One of the basic concepts others haven't mentioned is - for some items, it's much more efficient to store them on hand than rely on, or spend money on, shipping less product more often. Most non-perishable items can be tucked into a local (on site) storage area and just sit there waiting to be used at basically no cost. Moving that same product when it is needed has fuel and manhour costs, and risks delays if something unexpected happens.

The plastic dissolving in the water accumulates in the body. The effects of microplastics in the human body are underinvestigated, but it seems to reduce fertility

In pretty much any modern vehicle, the limiting factor in slowing down a car (other than crashing into something) is the traction between the tires and the road. The brakes in a modern car can always reach this limit and engine braking cannot help.

In any sort of real situation manually downshifting in an emergency braking situation is not recommended. Unless the road situation is hopeless (eg ice), the driver should be concentrating on steering and avoidance.

99.9% of drivers cannot heel-toe and rev match a manual transmission while doing 100% braking. That is not a skill anyone other than track or race drivers develop over many hours of practice.

Lots of metals are rare and have utilization. Historical valuation is the likely culprit. Platinum is far rarer than gold. So is palladium. They both have numerous uses for implementation, yet gold is far more expensive than both.

Food companies have to test their product to make sure it's shelf stable. The companies have no reason to test their product out past several months to a year. They have to put a date on food that they have actually tested, so even water gets a best by date.

They also accept some waste - particularly in produce, meat and bulk foods because it looks unappealing to have near empty bins. No customer wants to get take the last 3 apples from a nearly empty bin or the last package of steaks or whatever as it appears "picked over" or a lack of choice.

I mean the plow is behind the tractor ..?

Sure you might drive on it afterwards but from my experience a field is not a dry granular road surface like a gravel road. There's also way less traffic, the fields gets plowed frequently and sees almost no traffic. It also turns wet from rain and water and "moves" naturally.Completly different from a gravel road. On top of that the wiki article even recommends "plowing" the road to remove washboarding.

I am not saying that you are wrong because I am geniuenly interested to learn about this, i never thought about it before. But the arguments presented still have me sceptical. That being said the general idea you presented makes perfect sense, of course you'd want to "squish" the ground as little as possible with the tractor. I can understand that without any science.

Can you point me to any information on how the idea of this "expanding into nothing" can be conceptualized?

>and we're less drunk on the road.

You sure about that?

Gold has it’s uses like others said before, therefore there is a value in that.

Gold has a symbolic value due to it’s rarity like diamonds etc.

Also gold has a monetary value just like money or stocks etc. because it was used for exchange of wares. This one is simply through the belief of humans that these things have inherent value.

I cant say it much better, expect it also dulls the taste some, and in my thoughts they should bann bottled water.

Gold is very non-reactive so it will basically never naturally rust/tarnish. It is rather soft so it can be easily worked into things like jewelry without a forge. It's fairly rare, and has a unique color.

And in modern times it is very electrically conductive.

>Why is it used and so valued over similar metals with such properties?

There are no metals with similar properties.

Gold is rare enough to be sought after yet common enough to be gathered in usable quantities, absolutely trivial to mine/gather and refine, easy to identify, easy to work with, easy to alloy, non-toxic and does not tarnish or corrode away.

It's also shiny.

Rarity, scarcity and utility; all combined.

• Gold is relatively rare, you can't just dig a ground and extract gold.
• You can use Gold for purposes, such as chips, electronic devices etc. These are usually the more advanced and expensive tech, so gold gets a higher point there than other metals.

Thank you!

It doesn't.

The date is for the plastic bottles they come in. Chemicals from the plastic will eventually leech into the water over longer periods of time. As far as I know, this isn't dangerous, but it can 'taint' the water affecting the taste, which is why it's a best before date.

Worth noting a 'best before' date is just a recommendation - the product is still safe to consume after this date, it's just that it's likely past its optimum condition.

However, products with 'use by' dates should not generally be consumed past this date as they can start to be dangerous for consumption - ie, fresh non-pasteurised foods can grow harmful mould/bacteria.

You drive on it after plowing...

It's normal. Most large earthquakes have hundreds or even thousands of aftershocks, though most are too small to feel. Sometimes a single earthquake can have multiple main shocks too. Also aftershocks aren't really earthquakes, they're just everything that got displaced adjusting to its new position. depending on how much stuff was moved and displaced, they could be pretty destructive.

A given power figure on a shaft rotating at given speed will give the same torque. This is how it works. You can't really argue with this. So I say again, gear both drivetrains to the same output speed, and the one with more power has more torque
