    en.wikipedia.org/wiki/Help_talk:Displaying_a_formula

    There is at least one OCR tool that can convert a handwritten formula to Latex and other formats. Mathpix allows 10 snips a month free. I don't know enough to edit the body of the Help page (I've not yet used Mathpix so don't know how good it is, and how compatible with Wikipedia, and don't know what else is out there), but I think there should be a Tools section with this sort of information.

  4. Stefan's equation - Wikipedia

    en.wikipedia.org/wiki/Stefan's_equation

    In glaciology and civil engineering, Stefan's equation (or Stefan's formula) describes the dependence of ice-cover thickness on the temperature history. It says in particular that the expected ice accretion is proportional to the square root of the number of degree days below freezing. It is named for Slovenian physicist Josef Stefan.

  7. Joback method - Wikipedia

    en.wikipedia.org/wiki/Joback_method

    The Joback method, often named Joback–Reid method, predicts eleven important and commonly used pure component thermodynamic properties from molecular structure only. It is named after Kevin G. Joback in 1984 [1] and developed it further with Robert C. Reid. [2] The Joback method is an extension of the Lydersen method [3] and uses very similar groups, formulas, and parameters for the three ...

    [nb 1] [10] This poses the question of how naturally occurring ice spikes form in tapwater or rainwater and, Libbrecht and Lui have suggested that, in the case of the small spikes grown in a refrigerator, impurities will become increasingly concentrated in the small unfrozen droplet at the top of the tube reducing the freezing rate and so the ...

  9. Flash freezing - Wikipedia

    en.wikipedia.org/wiki/Flash_freezing

    Flash freezing being used for cryopreservation. Flash freezing is used in the food industry to quickly freeze perishable food items (see frozen food). In this case, food items are subjected to temperatures well below [clarification needed] the freezing point of water. Thus, smaller ice crystals are formed, causing less damage to cell membranes. [3]
