Ever used the Papain (Papaya) based meat tenderizer? I should know better than experimenting when I have more than 20 people coming over, but what the heck. Among other meats, I've got 6 tri tips marinading in a mixture of soy, worsh, wine, garlic, onion, and seasoned meat tenderizer.
Munroe effect and close relatives. Franz von Baader, in 1792 or 1799, discovered the process of explosive engraving, but this could not have been explosive forming in the modern sense, because he worked with black gunpowder, the detonation velocity of which is too low for what is generally called the Munroe effect.
Stark effect. The Stark effect is the shifting and splitting of spectral lines of atoms and molecules due to presence of an external electric field. The amount of splitting or shifting is called the Stark splitting or Stark shift. In general, one distinguishes first- and second-order Stark effects. The first-order effect is linear in the applied electric field, while the second-order effect is quadratic in the field. The Stark effect is responsible for the pressure broadening (Stark broadening) of spectral lines by charged particles.
