  1. I have Win7 and also can't delete some files in temp directory. It is normal. Any application can create (and keep access lock to) temporary files by using GetTempPath()/GetTempFileName() functions: https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-gettemppatha https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-gettempfilenamea Reread what I wrote in the previous post and identify which processes opened these files. And kill these processes/services. If process/service is shutdown, it should release exclusive access lock to temporary file. The real problem would be if files would be really big. *) You can try: edit environment variables e.g. change TEMP and TMP from default value: %USERPROFILE%\AppData\Local\Temp to something else. e.g. change to Temp2. Then restart the computer. Then you should be able to delete old Temp folder with the all contents (because it is no longer used). New temporary files should appear in Temp2 folder instead. Then rename environment variables back to the original value, and restart the computer once again. *) They can be e.g. automatic updates downloaded from the Internet.
  2. Production of a high quality pure product most often requires distillation and/or vacuum distillation to remove impurities.
  3. If the experiment was performed in the Fermilab, I would expect results being published on the Fermilab website. https://en.m.wikipedia.org/wiki/Muon_g-2 The reference was given in the Wikipedia article: https://news.fnal.gov/2021/04/first-results-from-fermilabs-muon-g-2-experiment-strengthen-evidence-of-new-physics/
  4. If file is at the moment opened by some application or operating system, it cannot be deleted. Files can be opened in read, write or read-write mode. Files can be opened in shared or exclusive mode. Exclusive mode means no other process can access (open) file. Process holds handle to the file. You can learn which file is accessed by which process using FileMon or SysInternals. https://docs.microsoft.com/en-us/sysinternals/ If DLL (dynamic-link library) is opened by LoadLibrary() function it can't be deleted, until the all processes call FreeLibrary() or shutdown. DLL doesn't have to have .dll extension.
  5. The metal is usually a very good reflector (mirror)....
  6. @Dem93 I would try to use distilled water instead of tap water, the next time you will be preparing and boiling saline solution in your stainless steel pan, to see if it makes any difference. Don't change anything in your procedure except replace tap water by distilled water. Water can be fluoridated and/or chlorinated in some countries: https://en.wikipedia.org/wiki/Water_fluoridation_by_country https://en.wikipedia.org/wiki/Water_chlorination additionally it may contain unexpected elements ("water hardness"), such as Ca2+, Mg2+ https://en.wikipedia.org/wiki/Hard_water Additionally, in some countries salt is iodized: https://en.wikipedia.org/wiki/Iodised_salt Sea salt contains much more elements than just NaCl: https://en.wikipedia.org/wiki/Sea_salt 15% are impurities.
  7. To create plasma arc use Van de Graaff generator. This is from my own: Alternatively you can build Cockcroft Walton generator https://en.m.wikipedia.org/wiki/Cockcroft–Walton_generator
  8. No. To create a current, a photon would have to be absorbed by an electron which then would be ejected from the medium's atoms and accelerated. The ejection of an electron from an atom in a medium requires the addition of energy. Such thing happens in e.g. photoelectric effect: https://en.wikipedia.org/wiki/Photoelectric_effect A photon passing though a transparent medium has to exit it from the opposite side (otherwise the medium is opaque). An opaque medium can: reflect photons, refract photons (in random directions) or absorb photons. (a transparent medium for photon with one energy/frequency/wavelength is often opaque for photon with different properties!) An alternative (and actually more common) thing that can happen after a photon is absorbed as it passes through a medium is heating it. Radiowave antennas are absorbing some photons, which accelerate some (a very few) electrons in the metal, in one direction, then in other direction (depending on photon properties). Therefore the antennas are connected to amplifiers https://en.wikipedia.org/wiki/Antenna_amplifier which detect these minor currents and amplify them.
  9. I think you have no idea what you are talking about.. When photon, with the right properties, passes through transparent medium with appropriate properties and there is applied external magnetic field, photon's polarization is rotated. It is called Faraday rotation. https://en.m.wikipedia.org/wiki/Faraday_effect and device is called Faraday rotator. https://en.m.wikipedia.org/wiki/Faraday_rotator
  10. The real world example of what OP said ("westernization of people"): How about ex-bedouins wearing cylinder hat, and Western country clothes: Westernization has good ("harmless") sides (like the above example) and dark sides. If you are unfamiliar with this term read Wikipedia article: https://en.m.wikipedia.org/wiki/Westernization
  11. The spread of disturbance around the world.. They are homemade. https://en.m.wikipedia.org/wiki/Qassam_rocket Just to remind you the plot of the events: https://www.nytimes.com/2021/05/07/world/middleeast/evictions-jerusalem-israeli-palestinian-conflict-protest.html
  12. Jews made impressive transformation.. Impressive in very bad sense.. Transformation from nation which was bulk exterminated during II world war - tragedy which aroused sympathy and compassion in hearts of people around the world.. Now they regained status of the most hated nation of the world. Impressive degradation..
  13. How about this? https://www.google.com/search?q=human+concentration+time "According to a study by Microsoft, the average human being now has an attention span of eight seconds. This is a sharp decrease from the average attention span of 12 seconds in the year 2000." https://en.m.wikipedia.org/wiki/Attention_span
  14. You mix (and put them in the same bag) investment banking, enterprise banking, with classical banking ("retail banking") i.e. an institution which just collects deposits from people with money/assets, and distributes them across investors which need funds to build new businesses. A successful businessman, with good business plan (which is carefully analyzed), will have the money to pay back loan and the bank will have the money to give their deposit owners plus interest. Interest of classical bank is identical with client's interest. They both want to build a successful business that works flawlessly. The investment bank/enterprise bank is often a hidden player i.e. knows how much other players (bank clients) put into some financial instrument, and having this abnormal knowledge is/can be actively playing against them, or employee of an investment bank can play against his/her own clients, or release info to other players (typically for bribe) to give them an advantage over other players etc. Even classical banking eroded these days i.e. because bank employees are receiving premium bonus to wage for every new loan they gave. Typically regardless of quality. From point of view of bank client which received credit and pays regularly loan installments is good client. From point of view bank employee what only really matters is quantity of clients, and amount of bonuses. i.e. bank's interest is against bank employee's interest (!) and he/she can play against institution in which he or she works for (by giving loans to people who will surely have troubles pay them back) ! Bank (in good classical banking) wants to have as few as possible 'bad credits'. Bank (in extremely eroded classical banking) wants to cause bankrupt of their own clients which received loans to intercept their assets (which is often the case in US these days.. what happened in 2008/2009 was "fixed" in the most worstest way). Classical banking eroded in many ways: consumption loans. Such are bad loans since the beginning! Because they give nothing worthwhile (maybe except volatile, a few day, joy) to the client which took them. Instead, often puts them into debts and troubles. Loans for Christmas Holidays? For better food, gifts to family and friends? Absolutely silly to take and give such loans! Every year, every holiday, I hear the same advertisements of quick and cheap loans around November and December.. If you can't afford it, you should not take loans for extravagances. The economic system and banking system on this world are totally eroded. Interest rates with variable part? Client for loan should know since the first day, before taking loan, how much will have to pay at the end, and any bit more. Regardless how long it will take to pay back. Currently you can take $100 and you might end up returning $1000.. Any attempt to fix the situation e.g. return back to positive interest rates would result in complete collapse of economic system, because borrowers would not able to pay them back anymore. Borrowers (individual and corporate) who took the money (with current minimal rates) and invested in stock exchange, would have to sell stocks (the all borrowers, at the same time), and stock markets would collapse. Then, corporations with loans by themselves, which used their stocks as guarantee, would be put into trouble and forced to sell them, forced to introduce optimizations i.e. sell assets, fire employees. etc. etc. The economic and banking system in this world is a "house of cards" ...
  15. I think people don't count correctly costs and energy consumption, because they concentrate just on CC side. The real existing paper money requires: ATM (millions of them!), terminals, delivery from/to banks/shops/offices/homes (delay), guards delivering money from ATM to/from banks (wages, fuel, equipment etc), additional security and staff in banks/shops/offices, printing and replacing damaged units from time to time, money safes and money counters in banks/offices/shops/homes, hard to measure cost of delay in transaction due to physical existence (e.g. consumer has to drive for money to ATM and return back).. etc. etc. Multiply by the all people on the world using physical money and I bet it will consume more energy than CC. Paper money must be recreated when it is too much damaged. It happens every couple months or years. Unlike coins, raw material can't be reused, so yours $0.05 per unit, is underestimated IMO.
  16. Which country is not volatile? Where is Roman Empire now? Ancient Greece? Egypt? They existed for thousands years and now.. gone..
  17. In "good old times" (before "invention" of financial instruments) money was a tool to buy somebody time of life. e.g. anybody can sow the seed, harvest grain and bake bread. All by himself/herself. But it all takes time. There are easy tasks which anybody can perform with none or minimal schooling, and as a result they have low value per second, and there are hard tasks which have extremely high value per second of work. They require specialist knowledge and/or expensive equipment etc. Wages of working people, prices of products, expressed in local currency, are methods of weighting time of life of different people. The introduction of financial instruments, then movement to "worthless" *) paper (or equivalent) cash, then movement to virtual money in a computer memory/storage, broke the all rules.. *) "worth as much as we agree", which is/can be very volatile (Forex) and artificially intentionally modified.. If everybody would agree "we work as usual and nobody asks for money for anything" entire world would still work, a lot of good things would happen. Nobody would steal and kill for (not existing anymore) money. Crimes involving interception of somebody money would disappear. Narcotics and crimes related to them would disappear. The only narcotics dealers would be the one which are addicted by themselves. Some would say it would be "world of slaves".. But right now this world currently is "world of slaves of money"..
  18. Sounds you never worked in IT corporation.. Some programmer told me that they (he and the team he worked for at a time) were making ~ 30 lines of code per month. Every change of line he made required meeting with senior software engineers, hours discussion, acceptance and sending to automated test drive taking hours or days, and manual test drive.. For somebody unaware, from external world, "lazy person" might be indistinguishable from somebody thinking how to do something efficiently, correctly, without introduction of new bugs and problems in the app which has millions of lines of code.. Techniques which are fast and cheap (for IT company) to implement, are usually slow and inefficient for end user of the application. Book writers, music composers, artists, programmers, often spend time on "nothing" (indistinguishable from nothing from layman's perspective), when in the reality they are doing work in their brain, thinking. Jobs which don't require thinking and creativity are easily replaceable by automats, robots, machines and computers. In physical work it is much easier to tell whether somebody is lazy or not by comparison of the results with other employees doing exactly the same task. In intellectual creative work it is much harder to compare employees results. ..wallpapers is low quality cheap finish.. Funny in the context of your previous statement "someone who spends all of thier time trying to find a way to do as little work as possible"..
  19. Counter example: salted water has higher boiling point than pure water. Brine has ~ 109 C. When salt NaCl is added, the freezing point is lowered and the boiling point is raised.
  20. @studiot Edible oils are not one uniform chemical compound. They are a mixture of saturated, monounsaturated and polyunsaturated fatty acids. What is the difference between e.g. refined olive oil and virgin olive oil? The percentage of fatty acids. Along with the difference in content, there are also differences in the physical properties of the entire mixture e.g. smoking point. A couple tables worth reading: https://en.m.wikipedia.org/wiki/Template:Smoke_point_of_cooking_oils and here table with percentage content they are made of, and how it influences properties (smoking point): https://en.m.wikipedia.org/wiki/Vegetable_oil#Composition_of_fats
  21. If you want them to have always golden color, crisp skin with nice interior forget about shallow-frying.. Try this: cook potatoes with salt, vinegar and sugar at least 15 min. Dry carefully using paper and put them for max 6 mins in deep hot oil. Some use mixture of two oils to have higher temperature. Shallow-frying disallows them to evenly fry from all sides therefore you need to double time of frying. If you want to learn how much they took oil measure their mass before and after frying using both methods.
  22. Reading you guys, I wonder whether you are living in a parallel Universe.. Meanwhile, in the real world: https://www.forbes.com/sites/niallmccarthy/2016/09/23/survey-69-of-americans-have-less-than-1000-in-savings-infographic/ "A new survey suggests that nearly 7 in 10 Americans have only $1,000 or less in their savings accounts. GoBanking asked 7,000 people around the country how much money they had set aside in savings accounts for the future, and found that 34 percent of them have absolutely nothing set aside." https://www.statista.com/chart/amp/20323/americans-lack-savings/ How can somebody being really happy knowing he or she is just two weeks out of work to bankruptcy (or homeless)? For most people, this is (or would be) an extremely stressful situation. (Hence the incidents of mass murder after dismissal from work of person "on the edge") Whether somebody earns $7k, $70k or $700k per year, does not matter. It does not tell about non-luxury obligatory spendings and debts. The stress of the person who owns a home bought on credit and knowing that its price is lower than the bank debt can have devastating consequences for mental health in times of economic crisis.
  23. If you buy new CPU you need to buy new motherboard (because CPU socket has changed) with new RAM (because memory slots have changed) with new storage/disk/drive (because you don't want to lose old data or old one cannot be even attached) with new gfx card (because old one would be bottleneck or does not match PCI -> AGP -> PCI Express.. VGA -> DVI -> HDMI) etc. etc. In modern times manufacturers of devices decide for you instead.. forcing people to puchase their products. They could be giving CPU as free gift (like dressing gown from essay) and if somebody would like to have any use from it, would have to buy all the rest of equipment. It is widely used in modern computer games: base version given for free to download but if player wants to have any chance with a more advanced players must get paid additions (and perhaps at the end spend more money than he/she would in old times buying box version). Electronics break after a while of use. Elements are designed in such way to break right after warranty ends plus a small margin. You can't get into a shop or manufacturer and request a replacement for an element. It is no longer produced. Every year or every two years they design new models which have incompatible parts. Even the cheapest things are redesigned from scratch. Everything is done to disallow reparation and to force people to buy new product every couple of years.
  24. Let's inverse equation and use division: 6 / (-3) = -2 or 6 / (-2) = -3 Division is the inverse of multiplication. And vice versa. (With a little exception) In the simplest case: 1 / (-1) = -( 1 / 1 ) = -1 Left and right side of the equation must be equal.
  25. (without reading comments above, so maybe somebody already pointed it out) A perfectly sealed object with fluid inside will behave differently than the same object with open air access, i.e. different temperatures and pressures will be required to change the state of matter. It is used to stupidify people by so called "miracle" e.g. https://www.google.com/search?q=naples+saint+blood+liquify which, from time to time, changes state from solid to liquid, and vice versa. Basically, water put it sealed bottle, won't freeze at 0 C and won't boil at 100 C. In the perfect gas equation v volume variable is constant so two other variables must change accordingly instead.
