With an optical microscope having a high numerical aperture and using oil immersion, the best possible resolution is 200nm corresponding to a magnification of around 1200×. Without oil immersion, the maximum usable magnification is around 800×. For details, see limitations of optical microscopes.

Instead of considering simple loss, which is deviation of P i from ideal value, we will adopt -log( P i) as single loss value. This way, small P i scores are highly magnified. But scores close to 1 are minimalized (we already understand it now). In the 2013 game “Grand Theft Auto V,” one of the characters says: "You're such a buzzkill!" This is an example of being annoyed or frustrated by someone else's negativity or pessimism, which could be seen as a "negative-nancy."
