These are the same thing, IMO.

Your brain makes various "guesses" and constantly fills in blanks about what it doesn't know. It creates 3D images from two 2D images. Sometimes, those shortcuts result in illusions. It's adpating to limitations.

Ordering of large finite numbers

File: 1578675762414.jpg -(72414B / 70.72KB, 620x466) Thumbnail displayed, click image for full size. Ordering of large finite numbers
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.

Okay so picture a number line on an orbit, spiraling around a central point [0,0,0,0,0]
[distance from center,change in angle,total prime factors,rotations,bearing]

so 1 is:
1 from center
1 change in angle
0 prime factors
0 rotations
2 bearing

which gives [1,1,0,0,2]

and n+1=n etc
[1,1,n+1,n-1,n+2]

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

Would a wooden plane gain speed by being painted in a low-air-friction surface, or would it get slower / stay the same speed because of the weight added by the surface treatment?

Oh, I completely forgot about golf balls!
Super thanks for the recap, it really helped!
But then, maybe it would be of help if one made the total definitive top of the layer on the outermost exposed edges to give those planes that are left exposed but flattened, would it help to make only that specific part as frictionless as possible?
Or would it be micro-optimization at that point?

I have come up with a method. I just lack the technical know how.
You would need basic laser technology, but modified so that the laser gas is generated from the surrounding air with an oxygen concentrator. If you could manage to push enough energy through it, you could have a cutting laser. Now, there are ways to magnify the laser into more of a blade, but the issue is a laser just goes on and on, it doesnt stop. So you would need a way to stop it. I suggest a telescoping heat resistant pole that extends when activated, at the end of which is a circular beam trap. Instead of one laser, this design would call for a circle of beams around the inner pole which would make a wider blade. The inner pole could also likely be used to block. The lasers would only be for heat.

Cons:
Cant be used for stabbing
is like a first gen prototype and not so combat worthy
im not sure a metal strong enough exists
im not sure enough power could be made portable unless a mini generator was invented

Pros:
would absolutely cut and burn,
would definitely resemble a lightsaber.
is absolutely possible

add ideas or use this stuff guys, lets become jedi

>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.

So with this 5G coming up we're hitting a new wave of protests, meetings etc etc about the alleged dangers of all kinds of microwaves, and I noticed a lot of people around me are absolutely convinced wifi, cellphones and even microwave ovens are horrible for their health.

I'm not well versed on the subject of the effects of certain wave lengths, but aren't all wavelengths we use in the modern world non-ionizing and incapable of causing cancers? Are there any real reasons to be afraid or is it just people being afraid of things they do not understand?

Well, electric fields act on charged particles. So, if there's say, a K+ ion in a solution, an electric field of sufficient strength would be able to control its movement.

Since radiation is an alternating electric field, they cause oscillations of charged particles. It is this mechanism that makes me warry, more than the actual transfer of energy from the wave to the body

But what you're describing is a transfer of energy from the wave to the body.
> they cause oscillations of charged particles.
This is a transfer of energy.. However, the powers we're looking at are insignificant. Millimeter wavelength (5G) barely penetrates the skin. Compared to the radiation you experience from the sun, it's not something you should really worry about.

Let's discuss how we could update and redesign our global infrastructure and cities, as well as building new ones, in order to better utilize the latent global energy available. Thermal/kinetic/wind/water/solar energy into electricity, and built into our infrastructure and cities. Can we utilize biotechnology? Nanotechnology?

>What would be the hardest parts of this process? It is too costly to redesign the old? Should we just build elsewhere? Maybe even in space or other worlds?

>What should these new infrastructure/city designs be like? Are there certain geometries or naturalistic patterns we can mimic to make our structures more efficient at weight bearing, flexibility, etc? Something out of Stark Trek or the Venus Project? The word "ecopotia" comes to mind here.

>Can it be done before we succumb to environmental collapse in the next 10-100 years?

>What will have to be changed socially, culturally, economically for these changes to make a meaningful lasting impact on our world for the better?

Geometrical structures, that are more optimized than grid.

We are already having troubles with enviroment, and when ice is gone, it can release some gas from the ice to atmosphere, no more melting ice as it gets warmer, change will be faster when Ice melts...

We already are out of time.

So we're all familiar with the Moh's scale of mineral hardness, which is based on which minerals can scratch which. But I'm curious about the topic of mineral "toughness", which is based around how easily a given mineral will crack, chip, shatter, etc.

Apparently this is much harder to measure, however, and I can't find much info on this topic online. can anyone help me find a list of minerals / gemstones ranked by toughness, or something similar?

(pic related, jade is generally agreed to be the toughest mineral, supposedly)
