他的公式推导过程并不严格，以至于不被后人承认。
爱因斯坦正是以清晰的物理思想推导出洛伦茨变换和质能公式而著名于世，有意思的是
这两个发现都不是爱因斯坦原创的。
Olinto De Pretto
From Wikipedia, the free encyclopedia
Olinto De Pretto (1857–1921) was an Italian industrialist and physicist
from Schio, Vicenza.
In 1903 De Pretto published a paper entitled "Hypothesis of Aether in the
Life of the Universe", in which he proposed (similar to Samuel Tolver
Preston in 1875) that matter moving at the speed of light would have kinetic
energy equal to mc2, based on his (erroneous) belief that mv2 represented
the kinetic energy of a body moving at the speed v. He then speculated that
ordinary matter may be considered to be moving at the speed c, agitated by
an ultra-mundane flux. De Pretto's paper was later included in the
proceedings of an Italian scientific institute[1]. According to de Pretto, "
the matter of any body contains within it a sum of energy represented by the
entire mass of the body[... ] Nobody will easily admit that, stored in a
latent state, in any kilogram of matter, completely hidden to all our
investigations, hides such a sum of energy, equivalent to the amount that
can be extracted from millions and millions of kilograms of coal."[2]
However, de Pretto's line of reasoning is not regarded as scientifically
meaningful by the mainstream scientific community.
