containing a solvent. The solvent was clear, but changed color

when the chemical dissolved into it. A light was passed through

the test tube to strike a photo resistor. A TYPE 7 photo resistor,

which has peak sensitivity with orange light, varies its

resistance as a function of light intensity, with the formula

R = (443)*(I^(-0.6692))

where R is in Kilohms and I is in foot-candles. Futhermore, the

minimum sensitivity of the photo resistor is with violet light,

which happens to be the color when thiothymolyne is dissolved

in water.

When the photo resistor is connected to the paddle input with

33 volt source, the resistance in Megohm is calculated by the

approximation;

R = (count)/209.9

The point of all this was an attempt to refute the results

obtained by Prof. Azimov, as reported in April 1948. The Prof.

had reported that thiothymolyne displays a negative "time of

solution" when dropped into water. Prof. Azimov may have been

correct. Unfortunately, meaningful results could not be obtained

from the above experiment because the Apple II is too slow to

measure negative time. Perhaps one of the new optical computers,

which operates at the speed of light, could be fitted with an

accelerator to operate faster than light, and thus be used to

measure negative time.

Of course, some of this is in jest. But such interfaces are

practical, within the limitations of the Apple II game port.
