if i get an inflatable house tent and fill it with sea water is it gonna be insulating? could reinforce it with easy to source bamboo too. so if it insulates good its a cheap house.
does an inflatable filled with air insulate more then a nromal tent thats just fabric or some shit? i dunno.
i wanna buy a military style tent thats fabric and buy land and have a cheap de-constructable house while i build one out of wood or something is why im asking this and why i want to live in a tent. but i've camped before and inside the tent was cold as hell, with a sleeping bag. i don't camp in tents year round though so i don't know how sleeping in a tent is. i've slept in a tent at some years and it wasn't as cold as i remember but at that time of year it isn't cold at all i don't think.

"Hey Guys,
I am an industrialist from the US. Our firm mainly belongs to the oil & gas industry. We are planning to start a similar firm in Toronto. Now we have an availability of forgings for our operations. We provide turnkey solutions, from forging and ring rolling to the finished machined parts. We are in a hunt for reliable dealers who have got Cutting-edge technology, Quality, and On-time delivery. We did not take any chance on the Quality of products. Could someone please help me to find a trustable dealer?
I have found one but not sure about this:https://www.patriotforge.com/markets-served/oil-gas/

At first I thought it was malware but Patriot is a legit company and does the things it's supposed to according to the post. Not that I followed their link, but I did look up Patriot Forge and that link seems to be the same as their oil/gas markets page

Not sure why someone would spam this here. I'm not sure what they hope to achieve by pretending to ask a bunch of stoners about machine parts.

No its a white guy, and the class is for engineering majors so i really wanted to get this out to everyone.

So the link grabbers what I need but 2 problems
you have to be logged in to access the files, so jdownloader isnt grabbing what i need,
And im not sure what kind of format the stream is. My university built the media player for the lectures
they use a digital white board and stream the video from the white board on top of the lecture video; you watch both simultaneously or you can click to expand the video from either source. So im stumped on the format

With any luck you'll find a direct link to the video. It might not be your first hit and it might be hidden in such a way that it's impossible for a novice to find it this way. I've even seen a ('illegal' movie sharing) site take me to a rickroll using this method

Maybe the Addon "DownThemAll" will work better.

3 dimensions

so i know a lot of you have probably come upon this internal conflict before. Why is space in three dimensions? it might not make sense to some, " well 3s odd, shouldnt space be an even number?"

but lets think about this in more detail. the most primary counting system is Binary. You need two numbers to count and form numbers, 0 representing no value, and 1 representing a value. The counting system is formed by associating the two primary values to positions associated with the base of the counting system to a power.

so for a 2 digit counting system, 0 and 1, you form numbers based on the associated sequence 2^position, ie 2 primary units of counting, base 2.

so forming a number goes something like this 2^0 represents the first digit, ie 0 and 1 are represeted by "0" or "1", ok so what about representing 2 or 3?

well 2^1, would be your next expansion, so 2 would be 2^1(1) representing a value here, and 2^0(0) representing none; three would be 2^1(1) and 2^0(1) representing a value for both, ie 3="11" and 2="10"

ok so what does that have to do with space? well lets think about this, values are represented as 0 and 1, either having a value or none, and counting is formed with 2 ie "10" as its foundation. So what is space? well its representing a value past our notion to count and form values, ie representing a value of 1 past our notion to count Ie "11" or 3

so in reality 3 dimensional space shouldnt be associated as an odd number but having a value past our notion to count, ie existence.

So if we extend that, what is our notion of time? or how some mathematicians and physicists put it, the dimension after space? well obviously it doesnt represent a value, but follows the trend of the next heirarchy past our ability to count ie 2^2, or in binary 100, so what is time if not an extension of our notion to count but not yet maintaining a reprehensible value, ie a location in space?

thought this was interesting, please discuss

better way of visualizing it
0 nothing
1 a value
10 counting
11 dimensions of space
100 time

the number 3 is actually the 4th value in a counting system, ie representing something

1 value
11 space

0 nothing
10 counting
100 time

Buy an mp5 gas mask and fitting 'expired' (but sealed) fp-5 (nato 40mm NBC filters)
if youre european itll cost you about 30€.

Have it and wear it when shit gets really bad.

I guess you could cut out the charcoal and make them useable for even more than 40hours. Way, WAY better than any disposable mask or even the superb half masks anon is suggesting.

And your only option at this point. Act quick, prices were already inflating a week ago

Is this anything in particular?

I'm looking for some sort of ordering or classification of finite numbers.
Not infinite numbers, I know about ordinals but I find them kind of boring by themselves.

So any of these numbers would be strictly smaller than the first infinite ordinal.
For instance

  1. Trivial numbers like 1, 42, 4354353843745897394759347592347 that can easily notated using a number base
  2. Numbers that can be represented by scientific notation like 2^256, 10^100, etc...
  3. Using power tower (up arrow notation) like 2↑↑↑↑3, grahams number (g64)
  4. Chained arrow notation like 2 → 3 → 4 → 5 → 6
  5. Numbers that can not be notated explicitly but can be referenced by their fast growing function representation like TREE(3)

is this possible ???
6. Something that has to come after that, like numbers that are too large to be referenced by a function representation but can be deduced by other means like a process of describing a function like using self modifying code...

Will be positing about these notations and functions once I understand them well enough.

its more of a number spiral.

>-n + (n + 1) = -n + n

your problem was taking n as a constant but not assigning a value, its n0, n1, n2 per iteration.

you're trying to cancel infinity with negative infinity, which when you normally do it also gives you the result 1=0

There are some uncomputable functions, i.e. functions that grows faster than any Turing Machine can.
This means there are number of this sequence for which it is impossible to prove an upper bound, for any logical system.
If you assume that there is no super Turing machines in the physical world, then uncomputable functions are literally bigger than the largest quantity that can be constructed using physics.

The STEM meme has been floating around for so long now that the people who associate themselves with it have a track record of behavioral patterns to analyze. One common behavior of the typical STEMfag is to loudly proclaim that they're more intelligent than those people who study the humanities and the evidence they provide of this is always someone else's achievement, usually the achievement of someone like Issac Newton who was an extensive studier of non-STEM topics and was able to achieve insight by not being a closed minded know-it-all. What is it about the humanities which upsets STEMfags so much? Why are those cringing cowardly sissies so frightened by things that can't be directly quantified? It seems so lame.

>We combined enzyme discovery, enzyme engineering, and pathway and strain optimization to realize full opiate biosynthesis in yeast. The resulting opioid biosynthesis strains required expression of 21 (thebaine) and 23 (hydrocodone) enzyme activities from plants, mammals, bacteria, and yeast itself. This is a proof-of-principle, and major hurdles remain before optimization and scale up could be achieved.

The opioid crisis is about to get a lot worse and the potential here is limitless. Psilocybin, THC, cocaine, you fucking name it can all be made with this technology. Genetically modified yeast are going to be the Nagasaki and Hiroshima of the war on drugs.

If you progresivelly filter it out of water, you may end up with something, then you can find them better producing maxima... Maybe the solubility for opiate means you can mix it with filter and then have a division where solution doesnt end up back in the huge mix.

Imagine, 1 cubic metre is one TON of it. Thats quite big and it fits in a garage.
