For 10-minute talk one equation
The 20-minute length talkcan contain at most three equations.
The policy paper can contain a few equations.
The centrality of the velocity of light c in special
relativity is evidenced by the energy E of a mass m
moving with momentum p:
E = (m2c4+
or slightly better: E = ( m 2 c 4 + c 2 p 2 ) 1/2 .
The resistance R can be written in terms of the current I flowing under a voltage V applied V across the resistor: R = ----. I
The resistance R can be written in terms of the current I flowing under a voltage V applied across the resistor: R = V/I.
Note the equation is part of the sentence and must be punctuated.
