  1. You should do it in safe mode.. https://www.google.com/search?q=restore+in+safe+mode Especially if safe mode is problem free..
  2. Simply buy 120 GB SSD drive in any neighbor computer shop for $15 and install fresh OS.. If it is not hardware issue it will help straight away.. Then you will be able to copy precious files from old drive. e.g. 13.59 usd on eBay https://www.ebay.com/b/120GB-Solid-State-Drives/175669/bn_56798086 Everybody should have emergency drive in emergency situations to be able to install fresh OS on it, and boot. And bootable pendrive with Live Linux e.g. Kali Live: https://www.kali.org/get-kali/ Any pendrive 4 GB+ will be good. Only 4GB on it will be used for data. But first, boot in safe mode, and check if it works good or not! https://www.google.com/search?q=how+to+safe+mode+windows+10
  3. You have to experiment by yourself with material at hand. Like I said earlier, I would drill very small hole e.g. 1mm, then 1.5mm, then 2mm etc. until reaching final size. There are mini drills for precise operations: https://www.google.com/search?q=mini+drill+machine I bought mine in an electronics store. They are used by electronic engineers.
  4. Try running OS in safe mode. https://www.google.com/search?q=safe+mode+windows+10 Does it help? Try restore system from restore point: https://www.google.com/search?q=system+restore+windows+10 ..it might be buggy gfx driver.. try downgrading..
  5. Pretty ancient CPU. https://www.cpubenchmark.net/cpu.php?cpu=AMD+A6-6310+APU&id=2290 I'd suggest buy new SSD 120 GB (it is 15 USD or so) and plug it instead of current drive, and install OS once again on it. If it is 25% and it has four cores, then one core in entirely stuck. In Task Manager identify which process is using CPU the most (sort by CPU usage - click on listview column).
  6. Complex stuff I am 3D printing but it is TPU. https://en.wikipedia.org/wiki/Thermoplastic_polyurethane There are others e.g. FLEX.
  7. ctrl-alt-del and you can observe CPU usage, memory usage, network usage. What do you get for each one? Start > Run.. and enter "Performance Monitor" and you have more detailed app for monitoring and/or recording logs about it. You did not give any details about your machine. OS version, CPU model (exact!), physical memory, drive is HDD, SSD or NVMe?
  8. This was also my thought, but silicone rubber is resistant to -55 C, which could be a problem in a typical home. "The embrittlement point of typical organic rubbers is between -20° and -30°C, compared to -60° to -70°C for silicone rubbers."
  9. In every material I drill in, I start with a smaller radius/size and then increase the bit size when I'm done. Bit by bit. You don't want to mill the whole size at once. That could damage the whole thing.
  10. There are lab frame of reference and center-of-mass frame of reference. Interaction between particles at relativistic velocity must be calculated in CoM FoR, and converted to lab frame to know how much energy particle should have to give expected results e.g. creation of charged pion particle after collisions of two protons, in CoM, protons must have >= 139.6 MeV kinetic energy, but because of conservation of momentum they need more. From two particles with kinetic energy (in CoM), there are created three particles with kinetic energy after collision. In lab frame e.g. CERN/LHC, one particle is at rest ("target" which is hit), and the other one, beam of them actually, is accelerated. After collision there is shower of new particles. Calculate in CoM FoR of these particles to learn the outcome. At low enough kinetic energy we skip relativistic part, and use lab FoR, instead of proper CoM FoR (as they would not differ much). "the same", "an identical".. such humanistic PoV.. When you measure the sound emitted by a person/car approaching you, and moving away, you get different results, that is not identical.. even in classical physics..
  11. @studiot@OldChemE BTW, do you know that there is fast trick to do sqrt in single precision IEEE 754 https://www.google.com/search?q=fast+sqrt+single+precision+ieee+754 https://en.wikipedia.org/wiki/Fast_inverse_square_root CPUs/GPUs/MICs designers should make it instruction in hardware to have ultra-fast sqrts..
  12. Solar-panel-like material should be built into roads and houses. When the "vehicle" flies above the road, they should transfer energy to the "vehicle" to keep it flying (i.e., without friction), and to accelerate it. The remaining energy should be used to light roads, houses, agriculture and industry. Solar power towers are also an interesting option in uninhabitable areas: https://en.wikipedia.org/wiki/Solar_power_tower I like it. The farmer is happy, the plants that don't need full sun are happy, land is wisely used, the farm vehicles are self-sufficient.
  13. Not really.. Existing file formats use IEEE 754 inside their files.. If you want to maintain backward compatibility and readibility of these existing files, you must support IEEE 754. IEEE 754 is supported by hardware, CPUs, FPUs, MCUs, GPUs. Trying to change the standard in the middle of the IT age would take a dozen years.
  14. Scientists who found a new unknown element in the Sun's spectrum did not yet know about fusion. The name was given only because it was found on the Sun (its spectral lines).
  15. "Everything is spinning down".. what an inappropriate/non-scientific choice of words.. Everything goes from a higher energy level to a lower energy level. Decay energy is used to create new particles of various kinds depending on available energy in CoM FoR. The most common particle is the photon (layman version "light"). Spinning object has more energy than non-spinning object. e.g. spinning flywheel vs stationary flywheel. Friction (interaction of e.g. spinning object with something else, which might be even a cosmic ray in vacuum) decelerates the one which has more energy and accelerates the one which has less energy prior interaction.
  16. What sockpuppets do? Follow strings.. If he is nominated by the Republican Party, the next presidential election will not be Republican Party vs. Democratic Party tournament, but pro-V.P. or anti-V.P., pro-totalitarian-regime or anti-totalitarian-regime..
  17. Dyson sphere.. https://en.wikipedia.org/wiki/Dyson_sphere The efficiency of the solar collector is 75%. e.g. instead of heating water with gas or electricity, you can have hot water for bathing or showering without energy costs.. but you have to take a bath at the right time of the day, not at any time.
  18. Not really.. "God's will" The destruction of the pipe makes it impossible to blackmail Europe by closing it and reconnecting it, at will.. so, it is gone, for real.. "God's will"
  19. @paulsutton"This periodic table depicts the primary source on Earth (...)" ... Helium on Earth is formed by radioactive decay, alpha decay..
  20. ..and I was talking about you making measurement of volume, thus indirectly measurement of mass, which you can gain using your technology.. If an engineer has a device made of, say, iron, with a density of 7.87 g/cm^3, and changes it to a magnesium-aluminum alloy, with a density between 1.74 g/cm^3 to 2.7 g/cm^3, he will immediately gain 3-4 times, for example, the device mass will drop from 1,000 kg to 220-290 kg. Show how much you can gain using your technology.. The air between the elements will weigh more..
  21. @StringJunkyUS military, politicians and media, use the word "neutralization" instead of "murder"
  22. Air has density ~ 1.29 g/L, Hydrogen has density ~ 0.09 g/L, Helium has density ~ 0.18 g/L. i.e. they are all >> 1000 times less dense than regular solid matter. Magnesium (the lightest structural metal) has density ~ 1738 g/L, Aluminium has density ~ 2700 g/L, and other metals even more.. Mg-Al alloys are used in engineering where low weight is recommended. How much volume do you want to convert from air to Hydrogen and possibly to vacuum? Try to calculate this based on the size of the device.. Multiply by above numbers and you will calculate possible gain.. and rethink if it is all worth it. IOW, what is so revolutionary about making balloon or airship?
  23. Gamma photon(s) can be emitted by the nucleus, and X-rays and UV photon(s) can be emitted by electrons transitioning to the ground state of the daughter isotope. The 1s orbital is vacant, so further electrons will have to decay via photon emission to reach their final states.
  24. Sometimes this is the case. If the exclusive mode of decay is electron capture, then a fully ionized atom cannot decay because there are no electrons in the shell(s). Beryllium-7 is an example of an isotope that has a slightly different half-life when metallic than in compounds. https://www.google.com/search?q=Beryllium-7+half+life+change
  25. If the Russians send new soldiers (>= 300,000) to Ukraine, it's high time to close all borders, with literally everything.. forever.. destroy bridges, just in case, etc.
