- Comment on How are roundabouts made? 1 week 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.

i am not sure, but what i think i read somewhere is “ren” (as in pa"ren"t), so you would go like my ren dropped me to school or something.

maybe it is because being so weak, it allows things to be come together, and eventually be strong enough, by power of family.

this is my work. Our revious results showed correct trend, but, r^2 = 0.2
- Comment on Damn 4 weeks ago:
in simplification, you could derive that curvature of the orbit is basically the force between objects, with radius, from the centre of mass. Once you know curvature at a point, you ca define a series of curves fitting, and substitute with other postions to find all constants. And what is curvature? you can find online, that curvature is just a function of second order derivative, and you just have to solve a second degree differential equation.

I don’t know what is concerning, me knowing how to read this, or being able to read this even when I am not from a sms generation (not that i am very youung, but where i live, sms was very expensive, so many people did not message untill we had internet based messengers)
- Comment on Surely this is the radical islam people are so concerned about 1 month ago:
No, this is radio-labelled radical islam, the star denotes the radio labelling, in this case, a neutron extra, the stable version has a mass of 786, with n = 478 and p = 308, n/p ratio of 1.551948051948052, which just so happens to be the highest n/p ratio of a stable element.
spoiler
en.wikipedia.org/wiki/Neutron–proton_ratio islamichorizons.net/the-myth-of-786 Also, I did not really knew of 786, I know that people collect stuff with 786 (my dad also had a few crrency notes with serial ending in 786) but did not know it had no officially recognised significance, just numerology and alphabet-numeric conversion

we can’t let the noble black hole keep all ye energy, ye shall liberate it
- Comment on logs are for quitters 1 month ago:
No, It is actually the light produced that we can actually use as a energy source, the limiting thing is, before completely loosing its kinetic energy to frictional heat, stuff falls into black hole, from where we can not get anymore energy back. If black hole is stationary, then its 6%, and if its spinning (and assuming the fastest spinning theoretically possible) - 42% (spinning black holes are smaller and have smaller radius of no-return

sadly black holes go to something like 42% conversion (source: some minute physics video i think)

- Comment on ain't your buddy, pal! 1 month ago:
they are kinda a gender neutral.
Bro is fairly commonly used as gender neutral word.
Man (as in my man) does not have an equivalent (my person does not havve the ring) - but originally, man was the gender neutral term for persons, and we user mer (as in mermaid) / were (as in werewolf) for males. that is how man was used. But that very well could also be due to bias in writing and archiving of stuff, I don not know much about this.

Ah, stupid me, obviously you have a nuclear reactor, what would you do else with loads on nuclear waste from the accelerators.

most don’t, most will just give you poisoning from ingestion (or plain old indigestion), or in off case cancers, but that is not “kill” enough
- Comment on ONE OF US 1 month ago:
probably spend about billion dollars to make some particle accelerators, or ask some existing lab to let you move all your stuff into there lab, since ognassen would not last for even a second (all nearby elements are basically same in this, ognassen being most stable), so you would have to move your collection to their lab to have a “complete” set

- Comment on How would world politics be like if the top 100 countries (in terms of military strength) all had their own nuclear arsenals? 1 month 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? 1 month 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? 1 month 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 Longest valid chemical formulae that speels outs words or phrases 2 months ago:
yes, but it is likely going to be NaBrO3, Br is very large, and for Br, +1 is not very stable compared to +5 (most likely with +1, we will have disproportionation reaction)
- Comment on Longest valid chemical formulae that speels outs words or phrases 2 months ago:
my initial guess would be that it is not stable (very likely we are going to have phase seperation, considering the size difference of atoms, but not sre)
