But it may be the only defense, however partial it may be, that Kaczynski's attorneys have. FBI agents uncovered a trove of evidence in his Montana cabin, including virtual signed confessions and a signature completed bomb.
1 Whenever the Moon, Earth and Sun are aligned, the gravitational pull of the sun adds to that of the moon causing maximum tides.  Spring tides happen when the sun and moon are on the same side of the earth (New Moon) or when the sun and moon are on opposite sides of the earth (Full Moon).
How frequent are tides? Coastal areas experience two low tides and two high tides every lunar day, or 24 hours and 50 minutes. The two tidal bulges caused by inertia and gravity will rotate around the Earth as the moons position changes. These bulges represent high tides while the flat sides indicate low tides. A lunar day is how long it takes for one point on the Earth to make one complete rotation and end up at the same point in relation to the moon.
