Hi. Many surveillance and phone and other cameras can be made to see infrared by removing their IR blocking filter in the lens. Is sensitivity to thermal included when the filter is removed; or the sensor works only to a near-IR and thermal sensing is not 'near' ? What is a thermal camera spectrum ? ~12um ? Is any common canibalizable camera sensor that can be used for 'toy grade' thermal imaging ? If you want, jump to time stamp 1:10 at --> https://www.youtube.com/watch?v=2YEvkOVCaNI

Good morning mister president of the U.S. You pretended to pacify the Ukrainian conflict by negotiating armament in exchange of resources and promoting peace. Mister Putin took Ukrania and now you want your turn to take Greenland ? Sorry, there is no Nobel conflict prize, no matter how many tantrums you throw. The king of Denmark told me that you cannot afford the purchase of Greenland. As you are an expert in real estate, perhaps would prefer renting, about one thousand kilograms of gold per month, as your dollar printing machines cannot afford to make pennies. Spreading your diarrhea to Europe will not help. Hope you have a bad day.

This episode video is about those small ones on soil surface --> https://tubitv.com/tv-shows/200021886/s01-e07-dry-lake-bed

I bought many slices of smaller as these (my favorite type) for presents along years. It is a good feeling having on your hands something that old out of this world. 😳 --> https://www.ebay.com/b/Muonionalusta/3239/bn_7023272052 --> Next will be a pallasite :

Yes, probed from color and appearance first, picked up by a magnet, analyzed in laboratories mostly for iron-nickel, and details of environment effects if desertic or moist; rust/deterioration/type/family/parent documented decently well in the videos. Interesting that most are visually discernible exposed on soil surface. From my understanding, meteorites explode to small pieces by atmosphere or impact spreading large areas on surfaces because their low masses being small, do not penetrate soils, being visually found by a trained eye, also metal detectors. Why they explode in fire I cannot tell. Presence of oxygen, have temperature, but what is the fuel ?

Saw several episodes on free "Prime" TV; each at a different location all over the globe. Do not know how many are available 'on-line' --> https://m.imdb.com/title/tt1487514/episodes --> https://pluto.tv/us/on-demand/series/6227a0d24e4cae001a317f8d/season/1 --> https://tubitv.com/series/300001256/meteorite-men

Good day. Watching an entertained TV program of people searching/picking pebble size meteorites on land surface, came to a doubt... Would those meteorites on earth surface be 'very recent' arrivals, as old arrivals would be deeply buried in substrates that now have been covered with layers of sediments ? Do all sedimentary layers form under water ? Also being low mass, did not penetrate to subsoil; and larger ones are always buried under eons of layers due to their energetic impact, showing like inclusions ? -Images borrowed from the web-

Hi all. Perhaps already posted years ago but from a foggy memory and poor search skills am revising it. A magnet M with poles (N /S) has loooong polepieces as parallel iron bars (=======) at each pole. N=========================================================================E M S=========================================================================E Is the attraction to an iron part placed across the bars near the magnet M , or halfway across the length of the bars, or across the end E showing attenuation according to distance from M ? -Trying to build a 3 metres long unwanted ferrous scrap picker/collector across a conveyor belt with a magnet at one end and two bars hovering the transported material- Next... What changes if E and E are joined ( ] ), or, if at the E end of the bars, another equal magnet is attached/implemented (S/N); would the attraction force across bars be doubled ?

Nobody can ruin Venezuela more than it already is and has been for decades. If I remember well, around 1968, petroleum was discovered there. That is 45 years x 360 days = 16200 days x 1 million barrels per day exported petroleum x dollars per barrel = the calculator just crapped. Where that country used such huuuge amount of wealth when they have no toilet paper to wipe their butts ? The same typical reason; their politicians ransacking all the time. It is not the removed president; it is all of them since ~1970. Let the justice decide if jailing their master is right or wrong. If the reason is drug trafficking, let it be.

Hi all. This is supposed to be a quantum-something animal I see pipes, tubes, conduits, wires, connectors and more goldish mysteries to me. What is in those elements ? electrons flowing in wires, chemicals, radiofrequencies, semiconductors, light beams, radioactivity, precious rare minerals ? Merging these things and virtual intelligence can turn the diarrhea of humanity to a bloody diarrhea of humanity. Will it take deities to harness its future use ?. Did not discern an off-switch.🤢 --> https://search.brave.com/images?q=quantum+computer&source=web

Mr. exchemist : It is a high precision now obsolete Cornelius brand, military-AirForce 3000+psi air compressor to supply machine gun and landing gear pneumatics for B52 bombers of the 80's as far as I know; national stock number NSN4310008974475 I use for scuba purposes. Am not in the military to have access to its manual nor know where to attempt finding a copy.

Thank you gentlemen. Could be my very strong paranoia... Do not want to risk it, perhaps one in 10 million people has that compressor, cannot compare with another 😥 Will use it normally, if it dies; well, it dies.

Thank you. Am more concerned about the connecting rods, crankshaft, bottom of pistons being submerged in the oil that floods the upper chamber and very violently churning instead of excess returning to the bottom oil pan. Inlet filter poses no obstruction. Exact manual is unobtanium. 😩

Thank you, sir. Would your comment above apply if the compressor, cold at ambient temperature is turned on for 3 seconds, turned off with no chance to warm up at all and finding no oil level at the sight ? Can you replace the word 'backpressure' with another that I understand ? Yes, starvation is the fear. If there was 'blowby' from pistons into the crankcase chamber; would that pressure force-push the oil downwards trough the mesh ? crankcase~~~~~~~~~~~~~~~~~~~~~~~~~~~~oil .........................................................................mesh oil level ____________________________ bottom of oil pan Oil rises to crankcase chamber by the central column. Oil returns to pan trough the mesh.

Hi all. Photons transitioning from air into yellow tinted water decelerate the same amount if entering green tinted water ? Or, a red color light beam and a violet color light beam get different deceleration entering into clear water ? What changes crossing trough media ? Its energy, its wavelenght, both, other ? Do photons crossing into a rainbow outputted by a prism experience several changes of speed according the color they are crossing ? (high chance for poor terminology above 😟)

Good day all. I would like your opinion. If deserves moving to engineering, thank you. This vertical shaft air compressor oil pan has a level sight, and a fill plug. Shows full level of the new and proper lubricant oil. Starting the compressor, the sight shows no oil presence. No oil shown at the sight while running. Stopping the compressor, the oil takes like 30 minutes! to show at the sight. But if when stops, the fill plug is removed; oil immediately fills the pan and shows at the sight. Asking 'experts', say "never noticed/check the sight when running" and... "if shows full oil when stopped, run it and forget it" But how to know if the oil pump suction tube is below oil surface and absorbing oil at the bottom of the pan ? Paranoia is killing me. I suspect the crankshaft upper chamber is creating some vacuum; or the pan is creating some pressure that with the help of the dividing mesh, oil does not flow down freely. There is no venting devices nor any debris. There is 2 'chambers' : the crankshaft above and the oil pan below, divided by a fine mesh shown below. Oil is pumped centrally up to the crankshaft chamber and does not flow back to the pan trough the fine mesh in the second image. Stays on top of the mesh while running 😳. What is going on ? I do not want to damage it. Thank you.

Hello all. You won 10 million on the lottery. After paying for the liquor excesses, and the psychiatric treatment visit, you go to collect the prize. You get a 5 million check and deposit it in your account. Next day you call The IRS (tax) office to congratulate them for making/getting/earning/taking from you a 5 million share with zero investment and not even moving a finger. They did not wait for the tax filing limit date to collect. The filing date limit is April 15 next year. Do you think the tax institution will return funds to you corresponding to the collection in advance of about 10 months ? If does not happen, where can you claim 'justice' to get back 10 months of a full prize amount juicy interest the IRS did not allow you to have ? -Totally hypothetic; you did not win a peanut- 😄 Neither did I.

Greetings... Am $aving from buying chinese artificial or yearly more expensive naturals for christmas... But when they 'fruit'; what is the process for the berries to add their essence for my daily gin become more intense flavor ? squeeze their juice ? boil ? distill ? mash ?

Or "engines", or "developers" or "platforms" or "assistants" or something else ? Like Canva, Perplexity, Gemini, OpenAI... Seems to be thousands of them. What name defines/groups them ?

Thank you, Ghideon. You did better than A.I. 😀 That is it. Perhaps I will make it appear bigger, like 10 metres diameter turbine, if I find the right words/commands...

Getting there... Wrong angle to the stream flow; changed itself to different wrong wheels... --> Question... Who owns the image copyright ? - - - The user of A.I. or Google ? 😳 Interesting river under river... 😄

It may be me; as I often goof... where did I this time ? The order of posts at ---> https://scienceforums.net/forum/25-computer-science/?&sortby=forums_topics.last_post&sortdirection=desc are not sequential. Also, at this same subforum ---> https://scienceforums.net/forum/25-computer-science/?sortby=start_date&sortdirection=desc same disarray ☹️ ¿?

OK. Will try "align" instead of the failed 'turn 90 degrees' or 'transversal'. It resulted very, VERY close to as intended.

Thank you ! 👏 Your suggestion yielded this; need to turn the turbine 90 degrees... 😀
