Yay or Nay: Microscopic Fans
If something is hotter than air, every atom on the surface emits energy into the air through infrared radiation or convection. The simplest way to dissipate energy is to increase the area that is in contact with the air. This is done by introducing partitions, irregularities, etc. Calculate the area of this thing if it did not have partitions compared to partitions like the one in the photo: It has a couple times higher area than without partitions. Radiator + air exchange fan is a typical configuration. The launching rocket does not need fans, as the air is replaced automatically. Increasing the area of contact between something that needs cooling and the air will result in faster cooling. This makes sense for a thing that is moving fast, such as a rocket taking off. Fossil fuel cars also do not need a fan on the radiator cooling the engine. The air coming into it from the front of a car going fast enough is enough. Your laptop will be accelerated to an abnormal speed while being thrown in the trash garbage can. If your question was whether it would be enough for me to statically cool my laptop using a heatsink when playing 3D games I would say that this is a rather poor idea. Unless you want to burn the CPU/GPU.

Silly question?
Maybe because of the units... Joule is kg * m^2 / s^2 so it has all three - mass unit, length unit and time unit..

Trump said "they get it [data] very easily"
I don't think I would have to, because any intelligent person would understand the OP.. It could be deduced from the context.. ..you have it in the title of this thread and OP.. Paraphrasing you - who is to judge who should get it, or not.. ? Knowing your political choices you wouldn't even give POTUS such credentials.. (so do I) You chose the POTUS so you got what you voted for.. so you have to live with it for four years (at least).. I don't see any problem with that.. This is silly. The hatred of the POTUS speaks through you. If POTUS (aka "TFG") wanted the data, he could simply ask Musk to his office and execute one line of code to download everything to a flash drive without any bothering about making DOGE etc.. Creating conspiracy theories by you? For real? HR hires and fires people at the request of senior management. Its job is not to optimize the structure. Unless it will be told to, but it was decided otherwise so it is what it is.. I think that Musk's group when reorganizing structures is more effective - after all, they have years of experience in this topic.. It speaks through you the dislike of TFG. Every POTUS wants to be an "executive".. and doesn't like to have his wings "clipped".. So does everyone.. This is usually done by looking for legal tricks to get around the law. The other side then makes other legal tricks to torpedo it. And this goes for years. Without or little things done. As if the Republicans undercut the wings of Kamala you would now moan how bad and stupid they are. If I see obvious foolishness and/or fraud I see obvious foolishness and/or fraud.. Harder is the case with some more twisted, more cleverly designed things. But I'm managing. I was talking about debts exceeding 100% GDP.. That's pity. Welcome to the new world of 2025. Wake up. Now you have the DOGE to optimize spending of gov.. You should be happy that finally the government will burn through less tax money.

Orban has been on Putin's leash all his life. Oil and gas from Russia to Hungary does not flow anymore. Now he has a chance to become a truly independent politician. Re-read Wikipedia link..

Trump said "they get it [data] very easily"
PiS ("Law and Justice") is not the far right... Far right burns Jewish flags in the streets, beats or verbally insults foreigners, etc. etc. From an economic point of view they ("PiS") are the equivalent of the US Democrats (increase taxes, take from the rich give the poor more money, increase government spending, increasing the impediments to doing business and taxing everything, increasing bureaucracy, etc., etc.). From a worldview point of view they are US Republicans (against abortion, against LGBT, two-sexes only, against migration, pro coal, gas and oil, human-made climate deniers, creation of laws that hinder the operation of RES., etc., etc.). Donald Tusk predates TFG by 30 years in politics. https://en.wikipedia.org/wiki/Donald_Tusk He was president of the European Council: https://en.wikipedia.org/wiki/Donald_Tusk#President_of_the_European_Council_(2014–2019) (who is the highest-ranking politician in the EU, if you are not familiar with the political structure of the EU) German chancellor, EU president, first-term POTUS in 2017. Too amused faces for the circumstances as far as I'm concerned - when POTUS talked about the termination of the climate agreement by the US.

Trump said "they get it [data] very easily"
How would they (Republicans electorate) know? They listen to Fox News, etc. ... Biased media, have it that they are biased. When "our" politician is in power only what he has done good is shown, and what he has done ineptly is distorted, or not mentioned at all. When an "enemy" politician is in power, exactly the opposite is done. Musk complained about censorship on Twitter, and when people started writing him on X in those Fact Checks etc. that he was telling untruths, their posts evaporated and/or their accounts were blocked.. Point of view depends on where you sit.

Trump said "they get it [data] very easily"
Your post is misleading on many levels. Which is due to your dislike of TFG. They did not gain "access to sensitive data of Americans".. They gained "access to current and former government employees".. Every company has a database of current and former employees. And HR and accounting people use them. How to download all the data from the database? Easy! One line of code: SELECT * FROM 'table_name'; and you have all the columns and all the records. Or simply copy the file directory if they had physical access to the server. No one had to bypass security if they received it (server access credentials) from POTUS. I can't imagine the work of such a department/agency (which is tasked with finding where the money is leaking and stopping it) without access to people's data. If you have a fuel leak in the fuel tank you are looking for holes. The existence of DOGE or its equivalent makes no sense without data. How they would send a quit offer if they didn't know who to send emails to (i.e. they didn't have first names, last names and email addresses) and who to send letters to (i.e. they didn't have first names, last names, home/correspondence address).. ? Send an offer to resign via Twitter/X.. ? I can imagine what the rumors will be if they do it this way.. DOGE is like the HR department. It needs to have access to government employee data to perform its operations. It's hard to wonder current and former employees that they don't want this department to run smoothly, because it will mean that they will lose their money.. Aiming to reduce government spending is by all means very desirable. Especially if this money is spent on foolishness, or even fraud. A country in which debt reaches nearly 100% is some kind of total pathology. You spend what you have, not what you will/may have in two years.. All of this crap is based on the assumption (which may be wrong) that the economy will at least not get worse next year, and that tax receipts and other profits will be at least the same, not worse. For the future I would recommend you to be more objective.

Yay or Nay: Microscopic Fans
A laptop is not a good device for playing games. Not even a so-called gaming laptop. It's just silly. Buy/build yourself from parts a normal desktop computer. You can then replace the CPU/mobo fans with water cooling systems. https://www.ebay.com/b/Computer-Water-Cooling-Equipment/131503/bn_661884 If this is not a satisfactory answer, try a laptop cooling pad. https://www.ebay.com/sch/i.html?_nkw=cooling+pad They have many external fans that dissipate energy from the laptop better than a table. Fans can run at lower speed so they are quieter. At least until their bearings break down. A good laptop has a processor connected to the entire body, which is made of metal, usually magnesium alloy (e.g. AZ91D 9-10% Al, the rest Mg). Energy is dissipated over a large area.

Ethics of veganism
..the right way of doing this is to create GMO bacteria which will create the all proteins etc. which are in the animals etc.. After that, the existence of animals will cease to make sense, and they will become only interesting as museum objects in the zoo.... ... just like people.. ..what pets? You are in a sphere with 6370 km radius prison and you can't realize it because of the infirmity of your simple mind.. People used to breed horses. After the 20th century they became expendable and now there are only tiny remnants of the previous population. The same can happen to the populations of cows, pigs and chickens. From the billions of animals raised annually, it will drop to hundreds of thousands or thousands or even to zero. Their growing population is correlated with human needs in meeting the demand for their meat. When this disappears, their population will also disappear like the dinosaurs. From a biological point of view, their prosperity is correlated with human demand for meat. If the demand disappears, their existence will also disappear, since they solved human needs.

Where Is The Science ?
If someone is a novice, it is you who contribute to expanding their knowledge. But this requires patience. How can a novice contribute without knowledge? Only by asking interesting and stimulating conversation topics.

Where Is The Science ?
I think part of the problem is that long-time users rarely start new threads in the science sections. If they do start one, they usually create a new thread in the Lounge section (like this one) or in Politics section. The best chance for a long-time user to start a new thread about science is in the Science News section. If you look at Physics, Chemistry, Biology sections, the people who start new threads are mostly newbies who have just joined. They come and go or are usually banned. The practice of (over-)banning people who have not been simply rude, is discouraging people from being active, which must result in the demise of the forum. Not just this one, but every one. No one wants to come to a club or disco where they know they will get a slap. In the course of time, also those newcomers will register less and less frequently to ask scientific questions - after all, they now have chatbots that will generate answers in topics that interest them.

Does anyone use ChatGPT or another AI ?
There is apparently needed a new definition of pirating.. Because if you (ChatGPT) read XYZ on a website and you (ChatGPT) output ABC as a result of a reading it.. I can't see it being a pirating/plagiarism anything.. Very simple inputs produce very simple outputs. But more complex input data gives a very different result. Enter some (e.g. this) sentence to a language translator from English -> French, then click it again a couple times, and every time you will get a different version.. Entrez une phrase (par exemple celle-ci) dans un traducteur de l'anglais vers le français, puis cliquez à nouveau plusieurs fois, et vous obtiendrez à chaque fois une version différente... Enter a phrase (such as this one) into an English-to-French translator, then click several times, and you'll get a different version each time... (Two last paragraphs created by AI = stolen from me! copyright infringement!)

Does anyone use ChatGPT or another AI ?
..just like any human.. you read literature and remember it.. and rephrase words from it when you need to.. It is a crap that you learnt from politicians and repeat this nonsense over and over again. Your post is an example of stolen thought of somebody else.. Often it is just one way to write something that is really simple. This does not mean that it is plagiarism or theft of intellectual property. You never had that intellectual property anyway (if one believes in determinism). Familiar movie quotes, just a few words, have become so popular that they have entered common usage, that no one can imagine that someone hundreds of years ago used the same phrases in some context from years ago.. If you use them, you will be accused of copyright infringement, etc. etc. but they are so simple that any idiot about figure them out at any time..

Garlic 'fries'...
1) grate the potatoes 2) grate the onion 3) grate the garlic 4) add eggs (optional) 5) add some flour (actually optional) 6) add pepper and salt etc. 7) Mix them together 8 ) place on a hot plate Call it "potato pancake".. Welcome.

How many colours can see a Tetrachromat in a Rainbow ???...
The problem with physics and biology is that the human eye is imperfect. Do you see the yellow color on your computer screen? It's just green and red LEDs. It is not a true yellow photon. A similar example is violet, which is a mixture of red and blue LEDs. It is easy to fool the human brain. You can create a grid with two different colors, and the brain will interpret them as a different color (which is not actually there).

How many colours can see a Tetrachromat in a Rainbow ???...
A 24-bit/32-bit computer screen is capable of displaying 16777216 colors. 2^8 = 256. 256^3 = 16777216. 1) Download some 2D paint program or use an online editor. 2) Draw a figure with a color of, say, 255,0,0 and another figure with a color of 254,0,0. 3) I can immediately see where the transition is between them. If you are not able to, your eyes are damaged and you need to go to an ophthalmologist.

plastic ABS doubt shocks protection Hard disk
Hot plugging/hot swapping https://en.wikipedia.org/wiki/Hot_swapping means you can plug or unplug a device without turning off the computer (older non-USB connectors require this, e.g. you can't plug in VGA/PS2 keyboard/PS2 mouse when the computer is on, HDMI/DisplayPort/DVI you can). Same goes for SSD/NVMe/pendrive/camera/smartphone..

plastic ABS doubt shocks protection Hard disk
This must be done ALWAYS, regardless of the date! It is not about parking heads, but about flushing the cache from memory to device. Without this, the file system can be corrupted and data lost. For the same reason, click "Start > Turn off computer" instead of simply pressing the power button.

Difficult 3d calculation needed
The volume (VOLUME! V=4/3 pi r^3) of the sphere / 2 (divided by two) must be equal to the volume of the dome on the left (from the 2D image) plus the volume of the dome on the right plus the volume of the cone with the right part cut off (the volume of the cone with height “a+b” minus the volume of the cone with height “a”). We do not know (yet) the values of a and b, but we know that the distance from the vertex of the cone to the sphere is 4 (5-1).

Difficult 3d calculation needed
So basically what is the purpose of this? The computer program will not give the formula, but it will give the value of the result.. I.e., you enter the radius of the sphere, the position of P, and some data about the slope, and the program will calculate the rest by itself. For example, you want to calculate the area under some curve. You can draw these figures using graphics functions and then count the number of pixels. With ease. If you have "step between pixels", treat it as 1/2. Repeat this for the Z-axis and you get the volume. Graphics cards now have thousands of parallel GPU cores. Handmade brute-force integration. The higher the resolution, the better the precision. If it's “for fun,” why should we do it for you? You should have fun coming up with the formula yourself. If we do it for you, you won't have fun.. And us too, because we will be used. Blender or another 3D application should give you an approximation - create a 3D sphere, create a cone, subtract these objects using the boolean tools, and the second time cut these objects and use the volume tool. After a few tries with a different slope of the cone, you will be well on your way to getting an approximate result.

Difficult 3d calculation needed
Do you need a formula or an approximate value (calculated by a computer program) for a real-world application? There are many tricks to write a program without creating mathematical formulas with enough precision.. I solve “unsolvable problems” with ease. A common example is dividing by zero. Any division by a variable must be checked before executing the code, otherwise an exception is raised (program crash and shutdown will occur). So basically what is the purpose of this? Can you write computer programs?
