The reason for sea waves was told to be the gravitational pull of the moon. Then what about the effect of the gravitational pull of the Sun on sea/oceans? If so, why not each and every lake also produce waves?

I recently got interested in Numerology. But some books are not adding up to be accurate. I do my name and D.o.b. and some books get my personality etc right on, and some books don't. What to you, is the most accurate book on Numerology? I'm not talking about the "best" book or "most popular" book, I just want the one that has methods and info that is very accurate. Thanks.

Shouldn't there be a correlation between the amount of daylight and temperature? For instance, wouldn't one expect the longest day of the year to be the warmest, and the shortest day of the year the coldest?

a 10cm long thin rod uniformly charged to +10nC and a 10cm long thin rod uniformly charged to -10nC are 4cm apart. what are electric field strengths E1 to E3 at distances 1cm 2cm and 3cm from the glass rod along the line connecting the midpoints of the 2 rods? i know the formula for an infinite line of charge is E=1/(4*pi*epsilon 0) * 2L/r where epsilon 0=8.85e-12 or E=2KL/r where K=9.0e9.

It happens to me very often (almost everyday) that I look at the time right when the clock marks 11:11 or 1:11. At the beginning I thought it was just a coincidence, but now it's starting to freak me out. Is there a meaning for this in numerology or any other methaphysical science?

If you open a tap in the kitchen and let the water fall into the sink, which already contains some water, you will sometimes see droplets of water fly up from the bowl. Are these droplets water from the tap bouncing back from the surface of the water in the bowl, water already in the bowl being displaced, or a mixture of both? Bearing in mind the height difference, is the answer the same when a similar thing happens when I (a male) sometimes pee into the toilet?
