  1. Code-locked briefcase also.. ? ps. It would be quite "unpleasant" to wipe out nuclear rockets starting to launch... from the sky... so better keep them on the ground..
  2. Nobody here will write entire essay about it for you. But I will give hint: emulators use it very often to speed up their work. Three letters abbreviation.
  3. Better example is pendulum. Bob has the largest potential energy at the maximum angle. https://en.wikipedia.org/wiki/Pendulum https://en.wikipedia.org/wiki/Pendulum_(mathematics)#Simple_gravity_pendulum
  4. Do you even realize that single couple hundred KB file (not to mention MB, or GB) has to be split to hundred little chunks... ? If transmission of single chunk e.g. 1 KB is corrupted, just resending single chunk 1 KB chunk is needed, instead of restarting entire transmission from scratch.. Nobody needs/wants 64 bits+ chunks.
  5. Nonsense.. You have IP v4 with just 4 bytes (4x 8 bits) per address = 32 bits IP address. but there is also newer IP v6 with much higher resolution. 8x 16 bit shorts = 128 bits IP v6 address. https://en.wikipedia.org/wiki/IPv6 You don't want to have too large chunks.. Even 1 KB can be too big (especially for 3D real-time games!).. Here you have f.e. discussion about packet sizes: https://stackoverflow.com/questions/2613734/maximum-packet-size-for-a-tcp-connection No, I did not..
  6. "graphics space"? Do you mean gfx card memory? They have much smaller capacity than typical physical memory available to CPU.. 1 GB, 2 GB.. while e.g. DIMM/DDR (on mb) have now 8,16,32 GB per single module.
  7. No, pointers to memory are not transferred through Internet. They are local to CPU. Files are the same whether you compress them on 32 bit or 64 bit machines. If file uses 64 bit integers, 32 bit machine can read such file without problem.
  8. No, no "more memory"... more data... higher resolution, higher precision integers, higher precision floating point numbers. 64 bit applications have 64 bit integers and 64 bit address pointers. So they use MORE MEMORY for the same. And they work slower than 32 bit equivalent application. But in some cases, when application is using more than 4 GB of data, it's necessary.
  9. You can compress data to store the same amount of data but in smaller buffer. Compression can be lossless or lossy compression https://en.wikipedia.org/wiki/Lossless_compression https://en.wikipedia.org/wiki/Lossy_compression In some cases like 3D graphics you can store information how to recreate 3D object with very high precision from scratch, instead of storing the all vertexes and polygons in raw format. e.g. instead of storing the all characters of every word of every page of text document, you can just store information about index of word (or entire sentence, often repeated) instead. And make dictionary with words. One common dictionary of words for couple books (entire library?) would allow even higher compression rate.
  10. You did not say in which area of science.. Van de Graaff generator https://en.wikipedia.org/wiki/Van_de_Graaff_generator Cloud Chamber https://en.wikipedia.org/wiki/Cloud_chamber Cockcroft-Walton generator https://en.wikipedia.org/wiki/Cockcroft–Walton_generator These are from physics.
  11. Some will say I am "prophet".. I am not.. https://www.nytimes.com/2018/01/02/us/politics/trump-tweet-north-korea.html "Trump Tweets 'Mine Is Much Bigger Than Kim Jong-un's'... "
  12. If spacecraft would have one side always pointing at the Sun, the other one to cosmos, temperatures wouldn't spread uniformly. One side would be always overheated, and the other one would be always overcooled.
  13. Lakes and tanks have three dimensions, width, height, depth.. You just have to reach deeper level with light. Vertical farms also use LEDs, R & B, with little G, to deliver light. ..as long as they are vertical farms.. They allow control what isotopes of Carbon get to plants (radioactive Carbon C-14 should be filtered out) and later to animal body and human body.. and allow better optimization of land and water.. That's the whole point. Microorganisms/algae don't require external source of power. They use whatever is delivered by the Sun. If you will be using nuclear plants to convert CO2 and H2O to fuel, and then burn in vehicles, why not deliver nuclear plant's energy straight to vehicles since the beginning.. ?
  14. Open ocean's farms of algae was my previous idea. But it also has some issues. 1) weather. 2) you can't use gravity to auto-separate fuel from algae/microorganisms (and they will die if concentration of whatever they produce will be too high). 3) If fuel is miscible with water, ocean would have to be completely separated from farm.. 4) you would have to transport them to land, and ferment on land, to convert them to something more usable. We can imagine GMO algae which have "fruits" filled by some kind of fuel. After squeezing them, fuel is released. Like olive oil extraction.
  15. Here is video tutorial how to mount (map) shared folder to virtual drive letter. https://www.youtube.com/watch?v=ZURjAaSGQRE Map network drive to some letter, and try whether it's possible to show content of it inside of cmd, using cd and dir commands.
  16. That depends on what you meant. Did you simply mean to legally display content of shared folder, or shared disk, or disk mounted in local network?
  17. How about other procedure: Genetically modify microorganisms and/or algae to produce fuel of choice *). Place them in in the middle of nowhere (e.g. desert) inside of large tanks, artificial lakes, pump to them carbon dioxide (solar panels) and fertilizers. Filter/gather produced by them fuel. *) ethanol is miscible with water. Benzene is weakly soluble with water. I think it's better choice, because it will be easier to extract from water.
  18. That's why many herbivorous animals have eyes with very wide field of view, near 360 degree (e.g. many birds).. They evolved to have "eyes around the head" to be able to see predators, and be able to escape them. On the other hand, predators, carnivorous animals, have binocular vision, to be able localize prey, and precisely measure distance. https://en.wikipedia.org/wiki/Bird_vision https://en.wikipedia.org/wiki/Binocular_vision https://en.wikipedia.org/wiki/Monocular_vision Bird's predecessors were carnivorous and used to have binocular vision, but some species lost it during evolution when they changed diet and became herbivorous animals. Binocular vision is useless for searching plants and fruits, monocular vision is useful to detect predators. Predators killed and ate binocular herbivorous birds, preventing them to have offspring (and spreading their genes).
  19. They are redshifted... no longer in human visible spectrum of light.. https://en.wikipedia.org/wiki/Redshift Add to it inverse-square law. https://en.wikipedia.org/wiki/Inverse-square_law [math]I = \frac{I_0}{4 \pi r ^2}[/math] Black means lack of photons at visible spectrum between 400 nm .... 700 nm.. Black materials are emitting photons in IR spectrum depending on their temperature. You can see them using IR camera. Analyze where is peak will tell temperature (that's how IR thermometers are working (from distance)) https://en.wikipedia.org/wiki/Wien's_displacement_law
  20. Do you have to? Everybody see it's wrong since the beginning.. In his vision: [math]E=\sqrt{G*D} \hbar[/math] [math]m=\frac{\sqrt{G*D} \hbar }{c^2}[/math] Replace m by me (rest-mass of electron): [math]m_e=\frac{\sqrt{G*D} \hbar }{c^2}[/math] [math]m_e c^2=\sqrt{G*D} \hbar[/math] [math]\frac{m_e c^2}{\hbar}=\sqrt{G*D}[/math] At the beginning he said [math]\sqrt{G*D}[/math] is frequency But Compton frequency of gamma photon created during annihilation of electron-positron pair will be: [math]\frac{m_e c^2}{h}=f_c[/math] Division by reduced Planck constant will give you angular frequency.. not frequency.. [math]\frac{m_e c^2}{\hbar}=\omega_c[/math]
  21. Dark material absorbs visible light spectrum... White material reflects visible light spectrum. Radiators increase area which is emitting photons in the all directions.
  22. Gravitational time dilation (in GR) has the same/similar influence on the all rocks here on the Earth. I was just explaining how age of the Earth is measured.
