    I send you by this message my sincere gratitude to all the players


    who generously give of their time in order to create a safer space


    for the old as well as the future generations of explorer of the Inner Core.




    It is thanks to your indefectible support and your unlimited courage


    that we can now sail more serenely in this sea which was other times


    hostile and without pity,


    it is with your help that death is no longer obvious,


    it is With your help that the noble community of CrossFire will continue


    to prosper for centuries to come,




    God Bless the Swat Community

    I create this thread to present you a tool that is great and that, maybe, can help you in life


    This is GT Text, a program which lets you extract a text from an image, photo, ...


    Having tested it so as not to rewrite all the description of a equipement, I have little to notice that it works wonderfully (as you can see with the image ulpoader below)


    Just scan a sheet, or download a picture on the internet then open it once in the software, then select the area has "decoded" then you will have a message with the text you want, then you will just need a Click on Continue if the transcription is good then make ctrl v for example in a text file, google translation, ...

    Two things are endless: the Universe and human stupidity. But as far as the Universe is concerned, I have not yet acquired the absolute certainty!

    liquid oxigen is magnetic


    Because the word magnetic is rather vague, you have 3 type of magnetic effect:


    diamagnetic
    paramagnetic
    ferromagnetic


    (Some materials, such as mu-metal has the property of having a magnetic permeability)



    Diamagnetic objects, ie, which magnetize in the opposite direction of the magnetic field in which they are placed. Levitation can be obtained when the magnetic force that applies to the diamagnetic object exactly compensates for the weight of the latter. It requires very high magnetic field gradients due to the low magnetic susceptibility of the diamagnetic materials. As a result, only a small number of materials can be avoided in large quantities in magnets commonly used in the laboratory. A number of research groups have recently used paramagnetic fluids to create additional buoyancy through the "magneto-Archimedes" effect. In this case, the object undergoes two additional forces: the classic Archimedes' thrust produced by any fluid and the magnetic thrust. For a gas at ambient temperature, for example oxygen, the conventional Archimedes thrust can generally be neglected because of the low density of the fluid. The "magneto-Archimedes" thrust supplied by a gas increases when the temperature of the latter decreases. Indeed, at constant pressure, the density of the gas is inversely proportional to the temperature. Similarly, the magnetic susceptibility of a paramagnetic material is proportional to its density and inversely proportional to the temperature. At atmospheric pressure, the magnetic susceptibility of the gaseous oxygen is therefore approximately inversely proportional to the square of the temperature, even in the vicinity of its boiling point.


    In the absence of a magnetic field, the molecules do not all have permanent dipoles (ex: O2, N2 ...). On the other hand, a dipole forms in the presence of a field, it is an induced dipole that disappears with the field that gave it birth.



    The liquid oxygen is a diamagnetic. ( if I'm not mistaken)
