I think the examples in the handbook are excellent, as an engineer I started on the pipeline example [1]. In terms of testing hypothesis, the design of experiments section is useful [2]. [1] https://www.itl.nist.gov/div898&#

This has basically nothing to say about epistemology besides “be open minded.” I wouldn’t recommend reading it. Yes, theories can’t be proven wrong or right, but philosophers have said a lot about truth that can point us in the right direct

I think the latter, since you can only reduce the pressure to the vapour pressure of the fluid. You get more bang for your buck pushing than pulling. Also the pressure can generally be raised above the design pressure for short periods, pip

Just have more nanobots guarding the brain blood vessels and breaking up any big bits?

Variable diameter pigs exist. For blood vessels you would want a nano-pig with an “iris” kind of mechanism which moves to match the vessel diameter. https://www.pigtek.com/products/dualmulti-diameter-pig/

I like this theory, very creative. However I don’t think it would work unless you control both ends of the pipeline, since you need flow in the pipeline to move the pig and this flow would be noticeable along the entire pipeline.

Engineering simulation software. So being hesitant to change code is probably fair, in case you introduce new bugs. However that view ties your hands when improving the software and at some point becomes counter-productive.

I’ve seen decades old Fortran codebases that everyone is too scared to touch. So instead all the new ‘features’ marketed to clients are just window dressing around the existing Fortran core.

Great article. Reminds me of a boss I had early in my career, who would get a bit nervous if you asked any questions about the details of what we were actually doing. I later found out it was because he just copied the procedures used at hi

That is definitely my biggest worry ocean-wise. I haven’t read many acidification papers but the impression I get is that ocean absorption of CO2 is relatively slow so we will only start to see noticeable changes on the order of centuries.

Again I disagree. The worst predictions for climate change are not based on very solid models. There are lots of clever people who are skeptical of the doomerism. As an example, the claim that more people will die from heat waves is correct

I don’t know of any good sources that cover this in terms of comparing policies. But most of my points (eg inflation negating minimum wages and the whole discussion consuming political capital) are self evident. The most extreme example of

Minimum wage changes are counterproductive in almost all instances. They consume a large amount of political capital, are rendered pointless by inflation and penalise those who produce less value than the minimum. There are better policies

This will make skin cancers slightly more prevalent in southern latitudes but I can’t see any other changes that aren’t marginal. It isn’t great but we are not “fucked” by any means.

The only reason I can think of is to avoid diplomatic problems. When scientific reporting doesn’t make sense it is either due to ignorance or politics, and I doubt the ESA has an issue with ignorance.

With better tooling this kind of status quo will change. Choosing a single worst case for design is a product of manual design processes. With modern computer technology we can run multiple cases easily, so we can now use probabilistic engi

I get what you mean, but there is no model that is used as a basis for trickle down policy, so it cannot be shown to be wrong. There are lots of studies and papers and economic tomes that argue for trickle down, but no model that a politici

Reread my comment, I’m questioning the policy. This policy isn’t the same as switching to EVs, in fact it may cause no switching! Let’s assume it causes 1% of people to switch and decreases the local efficiency of ICE vehicles by ~1%. This

by brutusborn 3y ago
You misunderstand my comment. To be useful for policy, the studies need to assess the _actual policy_. The reference you provided merely shows that new EVs are on average producing less GHG than new ICE cars. This is a separate question to

by brutusborn 3y ago
Even if everyone filled up this way, the policy would still be counter productive. Since gas stations are less common, instead of being able to fill up when you are at e.g. 1/4 of a tank, you fill up when you are at 1/2 a tank. Yo

I know they aren't equivalent, I just think they show that actions that most people would consider unthinkable (the state lying to justify a war) are in fact relatively common. Israel sacrificing the few for the many is only unthinkabl

If the Federal government builds a highway that increases your land value, why should you get the windfall from any capital gains? In this case the IRS collecting LVT is just recouping the investment they have made improving your land for y

Assessment definitely isn't easy, but some fairly simple solutions exist. For example, people could self-assess their land's value. To stop people low-balling the assessment, the Government could have an option to purchase the lan

That debate format is great, it would be even better if it had some tooling to convert the debates into knowledge graphs. The Yes/No format is essentially producing a tree of idea nodes, where a branch is created to investigate disagre

I think your example is a case where it would work well. Imagine Party A and Party B both produce models to estimate the effects of tax changes on job growth. Based on these models each Party produces a policy proposal. Party A is in power

The irony here is that this policy is very likely (almost certain) to increase GHG emissions. People that would have filled up at closer gas station now have to travel further. I wish these kinds of policies had an associated study to test

Is there actually any evidence of this? I agree with the mechanism you describe, but I imagine increasing temps by a degree would have marginal effects compared to things like forest management. If we want to reduce harms from fires, I don’
