Are there any treatments for severe depression which do not involve medication?
1) Change diet. Spicy ingredients such as hot chili are especially good because they stimulate endorphin production. 2) Train sports. This also stimulates endorphin production. Endorphins are natural opiates, painkillers which are sometimes released in response to the chilli's sting. Like opiates they are said to induce a pervasive sense of happiness. https://www.google.com/search?q=endorphins+stimulants

US-Roe vs Wade overturned
That's their twisted version.. Expect the prenatal testing system to collapse. Who wants to know that their future child is terminally ill and nothing will be done about it for months.. ? Miscarriage is a natural method to prevent the birth of a terminally ill fetus, that would not have survived anyway..

A Question for Curved Spacetime.
Complete, with micro-scale asteroids? They are made every day, every second.. new free particles in cosmic space, especially solar wind are emitted by Sun, planets, etc. so complete data is not possible due to never enough amount of data.. ..but to some level of accuracy, based on sizes of cosmic objects, it's not a big problem..

Javascript for Exponential Growth / Decay
I would do a for-loop for each column in the canvas, instead of going from 0...99. Then map the pixel screen coordinate space to the exponential equation space. Then convert the result of the exponential equation back to screen coordinate space. Instead of drawing a rectangle, draw a straight vertical line for each column.

A Meaningful Questions about Photons and Matter.
"Photons have no rest-mass because there is no valid reference system in which the photon is at rest..." So says the science. Do you know the reference system in which the photon is at rest? Particles with rest-mass can be accelerated and decelerated i.e. their FoR can be changed.

As I mentioned earlier, the correctness of the mathematical equations can be checked in the Wolfram Alpha program: e.g.: https://www.wolframalpha.com/input?i=x^0.1 (curve from #2 picture) https://www.wolframalpha.com/input?i=x^2 (curve from #3 picture) https://www.wolframalpha.com/input?i=x^1.01 https://www.wolframalpha.com/input?i=pow(x%2C1.01) (almost a straight line) JavaScript can print the log to a file or console: https://stackoverflow.com/questions/54654946/how-to-write-console-log-to-a-file-instead Log all variables on the console or in a file and analyze where the error occurred.. https://developer.mozilla.org/pl/docs/Web/API/Console/log pow(x,20) is very extreme: https://www.wolframalpha.com/input?i=x^20 99 is obviously even worse: https://www.wolframalpha.com/input?i=x^99 Due to the pixelated nature of the computer screen, this can be a straight vertical line...

Alternatives to z buffering
After a night, I was reminded of one trick on how to improve transparency support: - render the opaque polygons first (sorted or not (sorting a large number of elements is slow, but rendering things that are not visible and will be replaced by the closest one is slow too)) - sort only transparent polygons in reverse Z order (from farthest to closest to the camera) - render the transparent polygons. This means that only a small number of transparent polygons are sorted. It is good to have a user editable option to enable/disable sorting (this can be done for CPU, different algorithms and GPU accelerated version). Option to disable/enable transparency support.

Which is plain evil.. ...sometimes abortion is the only way to save women's life.. e.g. ectopic pregnancy https://en.wikipedia.org/wiki/Ectopic_pregnancy "In the developing world, however, especially in Africa, the death rate is very high, and ectopic pregnancies are a major cause of death among women of childbearing age." "The rate of ectopic pregnancy is about 1% and 2% of that of live births in developed countries, though it is as high as 4% in pregnancies involving assisted reproductive technology." https://www.healthdata.org/results/gbd_summaries/2019/ectopic-pregnancy-level-4-cause "There were a total of 6·69 million (...) ectopic pregnancies globally in 2019,"

Try Math.pow(x,y). https://developer.mozilla.org/pl/docs/Web/JavaScript/Reference/Global_Objects/Math/pow If y=1 you will get straight line for free. Values less than 1 will give you what you have on #2 picture. Values greather than 1 will give you what you have on #3 picture. How to draw an HTML5 curve on a canvas in a web browser: https://www.google.com/search?q=javascript+canvas+curved+line You can use the Wolfram Alpha to see what the curve will look like: https://www.wolframalpha.com/input?i=x^0.1

Alternatives to z buffering
Scanline's algorithm is: clear the screen clear the z-buffer (set Z to maximum) for each triangle, draw a triangle, check and fill the z-buffer with lower and lower values. https://en.wikipedia.org/wiki/Scanline_rendering Go from min-Y to max-Y of each triangle. Go from min-X to max-X of each triangle. If you start by sorting the polygons by their Z values, you will fill the Z buffer and the RGBA buffers only when Z is closest to the camera. Thus faster. However, if the geometry has transparency, you must start by sorting by Z in reverse order, that is, the pixels farthest from the camera are rendered first. (most 3D games do this because it is quickly implemented in the hardware) The pixel of the transparent polygon is a mixture of the old value (which is further away from the camera) and the semi-transparent, semi-transparent color of the triangle. (note it does not support refractive index!). Someone who doesn't want to use the Z buffer can change the algorithm to go from the top left pixel of the screen to the bottom right pixel of the screen, and then perform a for loop for each triangle. This will be slower, but the Z buffer will not be needed at all.

Tessellate triangles more.. won't work as good as z-buffer, but you might get better results than without..

Alternatives to z buffering
attach screen-shot.. BTW, if you don't support two-sided polygons, you can reject polygons with an incorrect dot-product between them and the camera, i.e. > 0 (which means that the normal of the polygon is facing the same direction as the camera, so it's facing away from the camera)

Alternatives to z buffering
Z-buffering is more reliable than sorting by polygon's z-position... Sorting by z-position is very slow, the more polygons, the worse it gets. Each polygon has a minimum distance from the camera and a maximum distance from the camera. The center of z will be at distance (min+max)/2. What z value are you using as a parameter for the sort routine?

Possible Experiments to Measure Effect of Impact Events on Sub Atomic Particles
@Alex_Krycek https://www.google.com/search?q=oxygen-17+asteroids e.g. http://www.psrd.hawaii.edu/Dec01/Oisotopes.html "The mixtures of oxygen isotopes in the Earth, Mars, and the asteroids differ slightly. If we knew why they differ we could learn more about the origin of asteroids and planets and the formation of the solar system." "The oxygen isotopic compositions of rocks from Earth, Mars, and the asteroid Vesta, the largest asteroid that melted, define three parallel lines on this plot of 17O / 16O vs. 18O / 16O. The lines are parallel because on each body the oxygen isotopes were separated according to their masses, when the rocks formed. Cosmochemists measure the 18O / 16O and 17O / 16O ratios in terms of deviations in parts per thousand from a standard (delta 18O and delta 17O). The usual standard is mean ocean water, abbreviated SMOW, for Standard Mean Ocean Water. Pure 16O would plot at -1000 parts per thousand on both axes. " "If you go to Mars and repeat the experiment you will find that the oxygen isotopic ratios follow the same relationship, but with one important difference. When you compare an Earth rock to a Mars rock with the same 18O / 16O ratio, you will find that the Martian rock has a slightly higher 17O / 16O ratio, as shown in the diagram above. The difference is small, about 3 parts in 10,000, but significant because oxygen is the only element that shows this effect, and because geological processes on the two planets cannot be responsible for the difference. (On Vesta, the largest melted asteroid, the corresponding 17O / 16O ratio is about 3 parts in 10,000 lower, and on the Moon, the isotopic ratios appear to be identical to terrestrial values: any difference is less than 0.2 parts per 10,000.)" https://global.jaxa.jp/article/special/itokawa/yurimoto_e.html "Using Oxygen to Trace the Origins of Meteorites"

Why are scientist using incorrect data for their studies?
Let me propose an experiment: put two long magnets pointing NS ....[space]... SN into a test tube, place vertically. put two long magnets pointing SN ....[space]... NS into a test tube, place vertically. They will repel each other and the one on top will levitate. Compare how far they repel each other (how much force kept them levitated)....

What would happen to our society, if we live for a millenia?
...what do you mean by "progress of society".. ? ...when you're at the top, the decline is swift and inevitable.... Quite innocent average Russian mans in just a few weeks were turned into mass murderers, war criminals, torturing people before killing them, raping women, children, elders... Were they pedophiles under the skin, dreaming of total freedom without inhibition or punishment, or was it their "leader" V.P. who set them up that way... ? https://en.wikipedia.org/wiki/Uruguayan_Air_Force_Flight_571 "The survivors had extremely little food" "Knowing that rescue efforts had been called off and faced with starvation and death, those still alive agreed that, should they die, the others might consume their bodies to live. With no choice, the survivors ate the bodies of their dead friends." "The group survived by collectively deciding to eat flesh from the bodies of their dead comrades. This decision was not taken lightly, as most of the dead were classmates, close friends, or relatives." "They dried the meat in the sun, which made it more palatable. They were initially so revolted by the experience that they could eat only skin, muscle and fat. When the supply of flesh was diminished, they also ate hearts, lungs and even brains."
