  1. Just after Thanksgiving, I finally updated my 7+ year old computer to a new "gaming"* computer. This has allowed me to upgrade Blender to the latest build, which has a number of new features and tools, as well as driving the render times down significantly. For example. One of the Star Trek matte paintings I tried to duplicate with Blender was of Stratos, the cloud city. While modeling the buildings wasn't that difficult, the clouds became problematic. In order to get the right look, you had to create a light scattering volume. This means that the render engine has to take into account how light behaves as it passes through the whole volume of the cloud. With my old computer, this meant hrs and hrs of render time, during which time I couldn't use the computer for anything else. I kept putting it off, thinking I would set the render going while we were away from home. Then Covid hit, and we weren't going anywhere. With the new computer, I decided to start the whole project again from scratch. (Mainly because the new version of Blender had a different model for making clouds) This is the result: In contrast to my old system, this render only took a few minutes. * Not that I do much in the way of gaming. It is is just that best the specifications for running Blender (good GPU etc.) tend to match those used for gaming. Though my daughter and her boyfriend did get me the newest Microsoft Flight Sim for Christmas.)

  2. Thank you for your quotations. Do you understand them ? The first refers to Griffiths in the Wiki article you quoted. But it does not tell you where. If you read Griffiths properly (pages 60 - 61) you would see that this 'total energy' is the energy you would have to input or withdraw to move a second charge in the field of of a first charge. I agree that Griffiths, like many before him, call it a test charge. But at least two charges are necessary for the equation to have validity. Griffiths deals with the general case of many charges in the section quoted.

  4. Rather than awarding negative reps to posts you don't like, why don't you address the point I made a moment ago? Is it because you have no answer? Or something else? I imagine your response will be yet another neg.rep. Still, it's something of an honour to be treated in much the same way as @Phi for All.

  5. Almost every one of your statements is easily refuted. I've chosen one at random. Thousands of meters below ground the rocks have significant porosity. The pore spaces are typically filled with sea water. Why would the viruses and bacteria be unactivated?

  6. According to the 20th Century humourist, former Presbyterian and balding Liberal Democrat, Area54, "All nonsense passes through three stages: First, it is conceived by a fool. Second, it is laughed at with disdain. Third, it is dismissed with a tinge of sadness for its author, the victim of Dunning-Kruger effect.

  7. Not a good start! The problem isn't that this is new, the problem is that it makes absolutely no sense.

  8. The problem here is that our sense of ‘seeing’ is a purely classical process - it’s light of certain wavelengths being reflected off macroscopic objects that simultaneously have well defined positions and momenta. But subatomic particles are not classical objects in that same way - so your question is, in some sense, a category mistake; quantum objects don’t ‘look like’ anything, because they don’t obey the classical principles which underlie our visual sense. If anything, you’d have to turn the question around and ask: what would the rest of the universe look like if you were somehow able to piggy-back along on an elementary particle? And I’m afraid I don’t have a good answer for that one. Don’t think of it visually at all - think of it as an abstraction, similar to how an emoji can be an abstraction of someone’s mental state. The essence of an elementary particle is that it is a representation of a set of fundamental symmetries, nothing more. In tech speak: it is an irreducible representation of a symmetry group. So the best and most accurate way to think of elementary particles isn’t as ‘things’ at all, no matter how tempting that may be, but as abstract expressions of symmetry.

  9. I hope this isn't another topic left abandoned by the OP. Started 8 December with this question - Can infinites exist in nature? What if the answer is yes BUT only if you consider mathematical objects that may not have any meaning in the real world. Classic Example: Send an object at a fixed speed from a start line to a finish line. Count the number of times the distance to the finish line can be halved. For example, at the beginning the distance was d. A bit later the distance to the finish line was d/2. Then it would become d/4, later it would become d/8... etc. You might say it was halved infinitely many times and eventually the distance to the finish line was 0. Was that something that happened an infinite number of times? Also, did it happen in only a finite amount of time, that being the total distance d divided by the constant speed s? Generally we (human beings with some liking for science and maths) say yes to those questions. An infinite sequence of events can happen in a finite amount of time. There are bucket-fulls of other examples you can consider. However, the event or thing that happened is usually dependant on some mathematical construction - the halving of the distance in the first example I gave. If you decided that space wasn't the continuous thing we thought it was but instead it was discrete or quantised then halving the distance isn't something you could always do. Let's say that the planck length may be the smallest little chunk of distance that you can have in the real world. Then you could only half the distace when there were an even number of planck lengths to start with. You have to approximate the division by 2 otherwise. There was a large BUT FINITE number of planck lengths from the start line to the finish line, so there was only a finite number of spatial configurations (approximate halvings of the distance) that could have occurred. There are a number of scientists working on the idea that space (and time) is discrete not continuous and if this seems valid and useful then the things you mentioned - Many Worlds theory (Quantum Mecahnics) and the Big bang (Cosmology and GR) are going to get a good re-think and re-formulation anyway.

  10. Since my last post, I've done a few more, Each one is a recreation of a matte painting used for the original Star Trek series. All but the last one have an element of "whimsy" added. at the end of the post I've added some comments and notes for each image. 1. Not exactly the reception Kirk and the landing party were expecting. 2. Duck Dodgers in the 23rd and 1/2 century. 3.The "Devil" in the Dark 4. Starbase XI Note: 1. Rigel VII fortress used in "'The Cage" ( first pilot) and later seen in "The Menagerie". It was also later used for Flint's home in "Requiem For Methuselah" My first try at using the "fur" feature of Blender to simulate ground cover/vegetation. 2. Eminiar VII from "A Taste of Armageddon". This was also used as Scalos for " Wink of an Eye". While Duck Dodgers is my self-created model, the other people in the scene are posable models imported from Daz-3D. About the only modifications I made with them were in the poses and coloration of clothing. 3. Underground mining facility from The episode of the same title as the caption. This one was also later reused for "The Gamesters of Triskelion" 4. Starbase XI from "Court Martial". Again, the base figures were imported from Daz-3D, though this time I had to do a bit more to make uniforms for them to be wearing. This one also offered some additional challenges. The perspective lines in the original matter painting were not exactly consistent. So in order to keep things looking as close as possible to the painting, Some of the objects in this scene are not "square".

  13. ! Moderator Note Seriously, you said this within your first three posts, on a SCIENCE DISCUSSION forum? You need to show that you're not here to argue in bad faith or troll for rabid responses to nonsense. You get five posts on your first day, so two left to add some reason and critical thinking here, or I'll have to shut this down as not meeting our minimum expectations for speculation. And our rules state you have to do it without forcing members to watch videos or go offsite.

  14. You make absolutely no sense. You've been told. Don't just engage in gainsay. Argue back. 1) Viruses cannot be placed at the origin because they have no mechanism for protein synthesis. 2) Coal is not present in the cosmos in any abundance. Only stellar moot --see below--, and carbon in rocks, mostly as carbonates. You might as well posit that humans are at the origin and nobody could tell the difference as to the internal consistency of your "theory". A primitive form of carbon may be something like this: https://aasnova.org/2019/04/24/hubble-confirms-interstellar-buckyballs/ A less primitive form of carbon is in carbonates in the rocks.

  15. Please read the rules you signed up to when you joined here. You would then know that you have posted your speculation in the wrong section and that advertising youtube vids is against the rules. You would also know that you have only 5 posts in the first 24 hours so don't waste them until you can scinetifically back up your hypothesis with evidence and answer scientific questions about it. For instance, the oldest known coal in this Earth is only about 10% as old as the Earth itself. Life has been known to exist for more than 80% of the Earth's history. More interestingly the oldest oil is much closer to the origin of life on Earth date. How do you account for this?

  16. In the beginning was coal ? NO. Coal was formed from plant material, which itself is a long way down the evolutionary chain from the simplest organisms. Viruses came before cells ? Again NO Viruese cannot exist (live and replicate) without cells so celss must have come first. Bacteria are not cells ? Really ? You need to seriously revise your chronology and understanding of elementary biology before proceeding to more complicated hypotheses.

  23. Please don't be biased. It is different from the information you have been taught before. Therefore, I understand your strange reception. I suggest you review my Youtube channel. Examine the biological combination theory as a whole. The Biological Combination theory is a huge advance in science.

  24. Most information you see as science is only assumptions. It has not been understood where the Coronavirus is transmitted from. Look, I'm explaining where you got it. Do research on this and debunk my theory. There has been research about viruses in the seas and oceans recently. Do not deny my theory from where you sit. Oil and coal are not the remains of ancient creatures. There is oil and coal 10 km below the ground. Is it possible to live 10 km below ground? It is very sad that you do a lynch campaign using the forum rules as an excuse. It seems that you are connected to the theory of evolution in the form of belief through an emotional connection. But there can be no sentimentality and faith in science.

  26. What is the Biological Combination Theory? Biological Combination Theory: While the Earth was formed in the black hole, the biological elements (coal dust) were randomly scatter to earth surface and to the lower layers of the earth. Living Things have formed on the earth's surface and in the soil close to the earth's surface. The biological elements that are far below the earth's crust remained as coal dust because they could not form living thing. Viruses have formed from the elements in coal dust. Viruses caused the formation of bacteria. Viruses and bacteria caused the formation of the cell of living things. Where do new viruses come from ? While the Earth was formed in the black hole, the biological elements were randomly scatter to earth surface and to the lower layers of the earth. Living Things have formed on the earth's surface and in the soil close to the earth's surface. The biological elements that are far below the earth's crust remained as coal dust because they could not form living thing. Coals are the seeds of the first life in the world. It is therefore the ancestor of all living things. Viruses are found in coal dust that cannot find life. Viruses that have been inactive since the formation of the earth can occur in 4 ways. 1-) Oil and natural gas exploration works in the seas : With sounding, viruses and bacteria that are passive thousands of meters below ground are activated with sea water. 2-) Deep earthquake cracks in the sea bottom layer : With Deep earthquake cracks, viruses and bacteria that are passive thousands of meters below ground are activated with sea water. Check out scientific research and articles on about viruses in the seas and oceans. You will understand that I am right. 3-) Global Warming : There are viruses and bacteria that are passive in the poles. With global warming, viruses and bacteria meet with sea water and become active. 4-) Water Wells : With sounding, viruses and bacteria that are passive below ground are activated with well water. According to the research, it is understood that human DNA consists of 5-8% Endogenous retro viruses. There are 20 bacteria in a human cell. In these research, he proved the accuracy of the Biological Combination Theory. Viruses have formed from the elements in coal dust. Viruses caused the formation of bacteria. Viruses and bacteria caused the formation of the cell of living things. Viruses are about 100 times smaller than bacteria. Bacteria are about 1000 times smaller than living cells. All living things, including plants, contain DNA and RNA. Viruses contain DNA or RNA nucleic acid. Bacteria are made up of endless combinations of viruses. Living cells, on the other hand, consist of an infinite combination of bacteria and viruses. The first living things were formed in this way as a result of biological combinations, each separately. They reproduced by reproduction after the formation of the first living things. After the first living things were completed separately, they did not turn into a different living things. The theory of evolution is also invalid in this respect. Today, living things formations in the ocean and sea bottoms continue. Covid 19 Samples taken from natural gas and oil wells should be examined in laboratories. Coronavirus is the most primitive, oldest and unknown virus. If it is not known how a virus originated and how it first got infected, it is very difficult to find the vaccine and control the virus. For this reason, scientists should consider The Biological Combination Theory to find the vaccine and control the corona virus. Origin Of Humans • Coals are not the old living remains, but the seeds of living creatures that have no chance to live. • Coals are the seeds of the first life in the world. It is therefore the ancestor of all living things. • During the formation of the Earth in the black hole, the biological elements were randomly scattered on the earth and near the earth's crust. The biological elements scattered on the earth have created living things. • The biological elements that are well below the earth's crust do not form alive, but remain as coal dust. • The deeper coal came into contact with the leaked gas from the center of the earth and turned into crude oil. • The chemical composition of the coals varies according to their location and atmospheric effects. Coals consist of two parts, organic and inorganic. • Now let's examine the elements that make up Oil, Coal and Human. These examinations clearly show that the origin of all living things, including humans, is coal. These examinations show that coal is exposed to various gases and converted to oil. According to recent researches, chlorophyll derivatives and hemoglobin were found in the content of oil. Chlorophyll is found in plants. Hemoglobin gives blood color. This research proves that oil is the first source of living things.

  27. You psycho, it's all verifiable. It's public record, much of it, and I'm happy to supplement the government's records with additional evidence. I wasn't asking for medical advice, you pretentious clown. I have no reason to value advice from you. It's political for the reason I said: science is being censored by the Oxycontin-pushing medical industry, thanks to whores like you.
