  1. In Special Relativity there are rest-mass (invariant-mass) and relativistic-mass. Massless particles like photons (light) have no rest-mass, but relativistic-mass.
  2. In the first post I read:
  3. Prior annihilation of electron with positron energy of both particles is: E= 2 mec2 After annihilation there are two gamma photons with energies: E = 2 h fc 2 mec2 = 2 h fc Reverse process is called pair-production. Compton scattering relies heavily on it as well. https://en.wikipedia.org/wiki/Compton_scattering https://en.wikipedia.org/wiki/Compton_wavelength
  4. Water is good example of intermolecular forces. Is has mass just ~18.016 u, when air gases Oxygen has mass ~ 32 u (~80% more), and Nitrogen has mass ~28 u (~50% more). Why isn't water gas like Oxygen and Nitrogen? Because it is polar molecule i.e. it has not uniformly placed electrons, and one water molecule bonds with other water molecules around it (forming weak Hydrogen-bonds). https://en.wikipedia.org/wiki/Hydrogen_bond#Water Yet another related subject is hydrophilic and hydrophobic properties of molecules. https://en.wikipedia.org/wiki/Hydrophile https://en.wikipedia.org/wiki/Hydrophobe (typically polar and nonpolar molecules)
  5. The problem with desert is that it has no significant amount of soil which is basically centuries and millennia of dead plants (natural compost). New plants to grow need nutrients. Where are these nutrients? In soil. Gathered from rain, and produced by other living organisms like bacteria and fungi. Water from rain quickly passes through sand, but it last longer in soil. During stormy weather there are thunders. They make NOx compounds, which fall with rain to soil. Plants need Nitrogen to grow. Without Nitrogen they won't be able to grow. It's often the case in plants growing in human apartment. They don't have access to rain, so after months and years soil is exhausted from Nitrogen compounds. I am catching rain on balcony and giving it to my plants. Alternative is to use artificial fertilizers.
  6. 1) did you get my message, or 2) did not you get my message.. ??? If yes, then be so kind and tell content of my message to you.. Thanks in advance!
  7. If we have 26 characters in alphabet (a-z) and no other characters, we could pack word to single number, using formula: [math]\sum\limits_{n=0}^{n<m} x_n*26^n[/math] Character a = 0, .... , z = 25 Word consisting of { x0, x1, ..... xn-1 } Quantity of characters-letters is 26, therefor powering e.g. 26^1 gives completely unused area than previous 26^0, etc. where we can store the next letter of word, etc. with other powers (positive integer n>=0) ASCII (8 bits per char) text is equivalent to: [math]\sum\limits_{n=0}^{n<m} x_n*256^n[/math] Unicode (16 bits per char) text is equivalent to: [math]\sum\limits_{n=0}^{n<m} x_n*65536^n[/math] Extraction of characters from such packed number can be done using pseudo-code: Number x; // initialize it while( x > 0 ) { int chr = x % 26; printf( "%c", chr + 'a' ); x /= 26; }
  8. Habitats, spaceships, rockets, infrastructure etc. and people are rare in cosmic space, at the moment..
  9. Replace in your question "element" by "isotope". "The abundance of helium-3 is thought to be greater on the Moon than on Earth, having been embedded in the upper layer of regolith by the solar wind over billions of years" https://en.wikipedia.org/wiki/Helium-3 https://en.wikipedia.org/wiki/Helium-3#Extraction_from_extraterrestrial_sources
  10. Years ago, on Windows XP, I had such issue: when you went to some specific folder in explorer, 100% of CPU and/or 100% of disk were used, blocking computer completely to unbearable level. Shutting down explorer.exe in Task Manager helped in this situation (or restarting and omitting said folder). I usually used reset button (quicker than waiting ages to open Task Manager). There was nothing fancy in that folder, just avi or mpeg movie. It was impossible to delete said file. Going to said folder using cmd.exe, cd or dir commands didn't cause any issues, it only happened from explorer.exe. del.exe from command-line refused to delete said file. It was possible to open and view file in media player.
  11. One again, boot in safe-mode, open service manager and disable them all... (make screen-shots, to remember original settings)
  12. It can be done using airplanes which are spreading silver iodide or dry ice etc. https://en.wikipedia.org/wiki/Cloud_seeding I think it depends on humidity of air.
  13. LOL! The above message was for the all who deny quantum physics and disbelieve in particles. When I am thinking right now, I wish my previous message to Arnold was so ambitious...
  14. I just sent you message mind to mind. Please write contents of my message to you. Thank you.
  15. Ancient Romans burned bodies after death. It released carbon dioxide and water. They are literally everywhere right now. It's the same with dinosaurs. If someone asks where the bodies of all long-dead prehistoric animals and plants are, the answer is everywhere.
  16. Apart of apps started from Run keys at boot, there are services.. But its harder to figure the one troublesome, because there is simply too many of them. You can see them entering "Component Services", then click on "Services (Local)" branch. Sort by Startup Type column to see which one have "Automatic", or sort by Status to see which one are "Started", then you could turn them off one by one, till there is difference in behavior of the computer. If you don't want them to start at boot, double click entry and change "Startup type" to Manual or Disabled. ps. You did not say (forgot?) results from SysInternals..
  17. You exist just because of automation of work on farms.. In older times, just 150 years ago, significant majority of population worked on farms delivering food for the rest working in other industries. There was no other option. Things significantly changed after discovery of artificial fertellizers and invention of agricultural vehicles at the beginning of XX century which accelerated growth and harvest of plants. Without them population of the world would be starving (having to be smaller). See North Korea. They starve because have not enough fuel and not enough modern vehicles. Majority of farmers work with bare hands (low efficiency per capita).

    You are making all this stuff when you are writing on forum... You don't understand how science works. There is observation of phenomenon and attempt to make equation which will allow interpolation and/or extrapolation of gathered data samples. You have been asked numerous times to come up with math equations to be able to verify your hypothesis. Such verification is done by scientists by feeding equation with data. Do you know what interpolation and extrapolation means? Prediction of behaviour of physical system.

    ...the key fact, that you miss is that you do not need while light source to confirm with what angle specific color light will bend its path.. Imagine: there is prism, and there are red, green and blue lasers, which you can turn on/off on demand. You turn them on, one by one, not at once, and you see where they hit at final screen..
  20. Try using e.g. SysInternals to figure out which registry key is modified when you change this settings in UI. Export the right registry to file. And add re-adding registry key each time comp is started (launch it by adding key (path to script) to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run).

    Teachers at primary school during showing splitting of white light to rainbow certainly don't tell kids about particle-wave duality. It is too early stage of education of kids (at least from point of view of current teachers). Full visible spectrum photons have different wavelengths/frequencies/energies with wavelengths between 400 nm to 700 nm. Photons with different properties hitting at prism surface, react slightly differently, their paths are bend at different directions, therefor separation of mixture of photons (white light) to rainbow (each wavelength goes independently from the rest). There is no need to mention particle-wave duality.
  22. Run in safe-mode. Start regedit in admin mode. Find: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run Once HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run Once What do you see? Make screen-shots and attach in reply. Rename "Run" to "Run2" (this will disable them all at once), and restart. Did it help? If yes, one of applications which are started at boot time is responsible for this issue. Rename "Run2" back to "Run", duplicate/backup keys, and start deleting (or adding from backup) them one by one.. This way you will be able to identify which one app is responsible for this issue. Or you can follow this instruction (not sure whether it is possible when running in safe-mode) https://www.howtogeek.com/74523/how-to-disable-startup-programs-in-windows/ Alternatively, when in safe-mode, make second user account. And log to it after restart. Did it help? What is in HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run is started regardless of which user you log-in at boot. What is in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run is started only when you log-in to user account (so after making 2nd user account, these entries will be not present, so apps won't be started).
  23. Obviously over usage of disk might be also indicator of lack of physical memory to perform some operation and virtual memory and page swapping must occur. It might be result of a bug in program, driver or system to use more memory than needed (memory leak), or result of hacker attack (e.g. DoS, DDoS). https://en.wikipedia.org/wiki/Memory_leak
  24. Heavy disk usage might be indicator of e.g. ongoing optimization of disk. OS is moving files from one place to another, where they are in continuous area, instead of being split to (hypothetically) hundred or thousands chunks. Reading fragmented file is very time consuming process as header has to jump from one place to another. Heavy disk usage might be indicator of e.g. indexation of files for faster searching files and directories. If it is not any above, search net for FileMon. It is showing which process is accessing which file in read and/or write mode in the real-time. https://docs.microsoft.com/en-us/sysinternals/downloads/filemon Later it was replaced by Process Monitor. https://docs.microsoft.com/en-us/sysinternals/

    White light is known to be merged mixture of photons with wavelengths in range between 400 nm and 700 nm. Kids in primary school learn that you can split white light to rainbow, as well as rainbow can be merged to form white light back again.. It is known as Newton's disc or Newton's wheel experiment. https://en.m.wikipedia.org/wiki/Newton_disc The rest is some word salad..
