most solids and liquids are practically incompressible (when comparing with gasses). there is a relationship between bulk compressibility, shear stress and youngs modulus for solids, which can be extended for liquids. It does not work for gasses

- Comment on How are roundabouts made? 2 weeks ago:
Well it depnds on what amount of cost you want to put in, and how are you making the roundabout, and are you going to put something on it, and essentially wht budgets you have. Where I live, we almost always have some statues or soemthing put on them.
They are made with essentially make shift compasses where I live. This is what is done for a roundabout of radius, lets say in ball park of 5-10 m. Initially marking is done (this is simply done by measuring out a tape of desired radius, and holding wwhen end at center, and other person revolvinng around it, and laying down something - could be simple as white chalk, or use jackhammer to make actual indents to ground, or lay down some bricks) This will serve as guide for curve, and any further curved elements could be made by just maintaining a constant distance from this circumference. Then the interior is usually dug to lay a foundation for whatever you put on it (could be as simple as excavating, and just plastering, but that is still expensive, often manually digging and then laying a firm dirt layer is enough). then it is covered with something (could be custom designed pizza slice shaped stone or marble wedges, but usually just bricks or cinderblocks). While making, we do not really make a great curved edge, and just make a n-gon, where n can be 20 or 50 or 100. This is simpler because straight edged bricks are cheaps, and you can lay them vertical, filling the gaps with plaster. The depending on your budget, you could get great finishing, again done with applying plaster, but this time, excess is applied, and some is removed, so we get a curved edge. Now you mostly have the exterior ready. On the top, you could have marble or stone, which can be grinded to match the curved edge, or it could be a thin plaster layer, which will take the shape of boundary.

sorry i am unware of it. I looked up, and from github page they are are remapper. They are great too, but they are a additional thing to install and run. For layers, you can already use keyboard shortcut to switch between predefined layouts in most setups, but thanks

I am sorry for your experiences, but my mother would differ. I know we (my sibling) were a pain in my parents’ ass, but our journeys are one of her most cherrished memories. I understand as parent it is not as stress free , you have to worry about safety and comfort of children, many times above your own, but I think that is a part of parents life, they have to bear this pain, but some parents also consider this not a pain, but cherrish this, they enjoy the cute moments.

It forces you to trust strangers and to lose sight of all that familiar comfort of home and friends. You are constantly off balance. Nothing is yours except the essential things – air, sleep, dreams, sea, the sky – all things tending towards the eternal or what we imagine of it.
Is that aa bad thing? coming from a introvert, but exploring the world is not a bad thing. Most things written just feel like someone too afraid of things to change. That could be a personal choice, but definitely should not be generalised. You learn different cultures, experience different worlds, get different perspectives, etc.
quoting from AVtar the las air bender (not sure if i remember verbatim, but i hope i am close)
You should learn from all nations, if you do not, your information gets old and stale Uncle Iroh
And I love Iroh, so heavily biased

I am not rich, and I do not get paid vacations, and I do not go to vacations often, but I still agree, it can help disconnect from life stresses. Money is a factor here, and we have not always been lucky in this, but sometimes, just a nearby place where you could get for cheap can be just as effective. You can choose to not to live in a expensive hotel.

- Comment on How would world politics be like if the top 100 countries (in terms of military strength) all had their own nuclear arsenals? 2 months ago:
One thing that would quickly start to happen is a lot of the smaller countries would either be forcefully taken over or be quieted down. Most countries have neighbours they do not share good relations with - and with nuclear armament - bigger of 2 could easily pose nuclear threat and have a much bigger say in their arguments. This could mean taking over contested/disputed lands or some kind of minearl deals being forcefully signed. Soon the total world country count would start to decrease purely because of this (annd would actually accelerate until a point where most countries would form coallitions with some nuclear power and sum total of power on both (or all sides in general) be roughly comparable such that no one poses a greater threat to another and not have an equal threat back at them.
- Comment on How exactly are people lighting Teslas on fire? 2 months ago:
Particularly for electric cars - you have very inflamable lithium batteris, which when spiked very hard (by something sharp), so multiple layers short circuit and well short circuits leads to fire. But batteries are at the bottom of the body, with few easily exposed areas (otherwise they would be at risk of explosions all time). I do not know what people are doing exactly, but you can use a crowbar like thing to hit the beneath posterior, until you expose the battery, and then 1 or 2 hits can do it, or you can skip this and use a smaller conventional explosive.
I would like to add this - I do not condone arson. Even if anyone wants to protest - this is not the way to do it, unless you burn your own stuff, then you are only harming environment. What i wrote is purely for educational purposes.
- Comment on What are some slow acting poisons? 2 months ago:
well you can try to look it up - slow acting poisons in minecraft.
on a more serious note, as others have noted heavy metal poisoning like mercury or lead.
I have another one - sulphur. Readiy available throughout ancient times, and non-toxic by itself (S8 form that is). But many of it’s compounds are toxic in varying degree. You can look its wiki page (en.wikipedia.org/wiki/Sulfur) for some commonly available toxic salts, but I also have some ideas to incorporate in story - burning of sulfur (in incomplete form producing SO2 en.wikipedia.org/wiki/Sulfur_dioxide). You can incorporate it very easily (someone tampered someone elses fireplace or incense sticks if we also want to hide any wierdities with flame). By itself it iis not very toxic, almost odorless, and not a strong color. It has existed even in food stored for long time due to degradation of sulfur containg organic compounds, wiki page also lists that wine this (another potential vector to supply this). When in body, it can produce H2SO3 (sulphurous acid) and by inhaling/ingesting small amounts for long time - it will gradually destroy alveoli/stomach inner lining and liver. Sulfur by itself is very cheap (you can find ores in a lot of places around the world, relatively easy to mine, also found near volcanic places), humans have used it in trying to make medicine out of it, and it has huge amount of history in alchemy (en.wikipedia.org/wiki/Alchemical_symbol, thoughtco.com/tria-prima-three-primes-of-alchemy-…). In fact, since it is present in humans naturally, and msot organic matter for that matter - small amount of sulfur being present in someones’ reports will not raise a special eye, and they would just be recommended to not eat food that is traditionally know to have much sulfur (for example garlics (en.wikipedia.org/wiki/Allyl_isothiocyanate). Garlic extract can also be used to deliver large amount of isothiocynate, but this would be a seperate method of poisoning all together - it is much more lethal, so not very slow acting, but one can keep giving a dose of this below lethal dose to keep damaging liver, and a final blow sometime.
I hope you find this helpful, and I hope no villagers in minecraft are killed by this.

- Comment on Swimming pool, blind dog 3 months ago:
maybe the kiddie-floaty like things (or the adult versions) in case the dog fells into water, then he may have something to hold onto/get on it. Also maybe some wooden slabs (plastics would be cheaper but would not look good, and they may even fly away in strong winds, but handling wooden slabs maybe harder because of weight, may be a 2 person task to take them on and off) cut to shape of your pool to cover it completely/partially. This will reduce the chances of doggy unknowingly (that is to you guys would know if it is risky for him to go outside or not) fall in the pool. This will also double up as ypour general pool cover to keep your pool water clean, and can also help you insulate your water better, in case you live in a frigid climate and heat the pool, or in some very hot climate and want to keep your water cool.
