To use MathJaX, put your TeX code between [ math ] ... [ /math ] tags for inline equations or [ eqn ] ... [ /eqn ] tags for block equations.

[eqn]\zeta(s) = \sum_{n=1}^{\infty}\frac{1}{n^s} = \frac{1}{\Gamma(s)}\int_0^{\infty} \frac{x^{s - 1}}{e^x - 1} \mathrm dx[/eqn]

Note: You may preview the output by clicking the TeX button at the top left corner in the quick reply window.

every photon of light you see is only an by you. if 2 people look at the same thing then the light produced by that thing is shared between them. what if a billion people look at something? would the light start to dim as a result of spreading the distribution of wave collapses? could we all drain the light from the sun by looking at it?

Dimensions are what fills space, such as the dimension filling our space is black. Depth, length, width, height, volume, etc are space fillers i.e. dimensions. A cube is not a dimension, it's a shape, though a dimension cubed would be the abstract of a cube. It would be similar to a cube unfolded accept it would be through space fill.

Lux is some bastardized corrected for human eye perception by wavelength bullshit. Your numbers are vaguely correct for human eyes but for panels turning light into watts, panels typically produce about 0.1 to 0.2 percent of daytime power in moonlight. Maybe the stars or cloud reflections contribute. Anyway yeah you can get fucked up if you touch solar panel wiring at night. You still need to lock out tag out panels not just wait for sunset. Trust me you will get fucked up if you try crimping connectors at night thinking you won't get shocked. It's not a lot of power I suppose if you'd get vaporized during the day for the same panels....

>>16785660
Sounds like it works good for you but it relies on others not using solar so your excess can be provided to them through the grid and then you can pull non-solar power from the grid at night. If everyone goes solar, your system no longer works for you nor their systems for them.

there's non-zero probability that you find electrons away from the atoms, and crests of those waves are where the probability reaches a local maximum
everything is wavy, so there are interference effects too influencing the pattern you see
>>
>>16785057
>>16785060
>>16785300
Correct, the atoms interfere with each other like waves, and their position is uncertain so with a measuring device with high space and time resolution they show up as wave patterns of high intensity (higher counts of detection) and vice versa

Earlier this month, a huge team of stem cell researchers dropped a very significant paper identifying Glutathione S Transferase Alpha 4 induction as the primary mechanism by which OSK reprogramming rejuvenates cells...
>Reprogramming Factors Activate a Non-Canonical Oxidative Resilience Pathway That Can Rejuvenate RPEs and Restore Vision
>https://www.biorxiv.org/content/10.1101/2025.08.30.673239v1.abstract
>GSTA4 overexpression alone enhances mitochondrial resilience, rejuvenates the aged RPE transcriptome, and reverses visual decline. GSTA4 is consistently upregulated across diverse lifespan-extending interventions suggesting a broader pro-longevity role. These findings uncover a previously unrecognized protective axis driven by Yamanaka factors that circumvents reprogramming, providing therapeutic insights for age-related diseases.
Soooo... is DWS's protocol fully deprecated at this point? Just cycle various GSTA4 inducers? Are there some other chemoresistance enzymes out there too that you should just cyclically jack the fuck up, unless you're a cancer patient on chemo?

Be warned friends.

Over the years I have learned to recognize a certain type of woman who is irrationally malicious. Among other characteristics they all have the same sort of smile.
She has this smile.
They are to avoided at all costs. Any unavoidable interaction with them must be kept to an absolute minimum. The best strategy is to feign being a pleb, as these creatures prefer to target anyone who sticks out from the crowd. If you get on the wrong side of them they will devote insane amounts of time and energy towards making your life Hell. What might seem trivial or inconsequential to you they will make the focus of their daily existence. They will plot and plan and then ambush you over something you entirely forgot about days ago.
Be very careful if they appear to be friendly. They are just looking for rope with which to hang you.
They are the intellectual equivalent of She-boons who have learned to get their way simply by screaming the loudest and longest, winning by simply being so persistently obnoxious that no rational person wants to engage with their antics.

That's a different argument about abiogenesis or whatever, and it's very copey since any odds given to this "lucky roll" are entirely made up. You say billion trillion but I could say billion trillion billion trillion etc.

this argument only works if you assume space-time isn't quantized. If so you can only describe time (or space for that matter) as small as 1 planck length unit, so the number of universes where you post a comment in that second would be finite. Its still unconfirmed whether space or time is quantized so we can't know for sure.

Here is a better filter question.

You and your opponent each draw a decimal number between 0 and 1 without revealing it. You each have the option to redraw and keep that value instead, and the other person doesn't know which choice they made. The person with the higher number wins. Find the optimal strategy.

I'm too lazy to calculate the exact threshold for redrawing, but it's probably significantly lower than 0.5 because the opponent is going to redraw low numbers too.

yes. if you picked a gold ball first, there was a 2/3rds chance that it came from the box with two gold balls. the next ball picked from that box must be gold. The other 1/3rd of the time, you picked from the box of mixed balls, so you'd end up getting the silver ball.

You're selecting for a gold ball, it's not 2/3, dipshit.

Stuff involving conversion factors between units, and.. maybe a qualitative comparison between two people in an example scenario with incomplete information? so uhh testing something like implied transitive properties

sure, most reasoning we do is ""just"" using logical operators, induction, [Bayesian] inferencing, paired up with rote memorization and an ability to adapt old concepts to new scenarios

on the other hand, people tend to call Large Language Models "intelligent", A.I., when it is ""just"" an optimized, [directed] weighted graph that is combined with Linear Algebra using Matrices to make predictions

What part of the algorithm was new? The use case was new, I guess. Synchronizing observations across the globe was the hardest part. Maybe atmospheric noise/distortion was a new ingredient. The AI shit that tagged along was strange.
If nothing was really new computationally and it was just an implementation feat, shouldn't the implementors get more credit?

They got their woman in STEM and a black hole "picture" for the woke news so who cares.
