Some skeptics say that speaking in tongues is not real because the speaker is not stressing syllables.
Is there really a need for official-type grammatical or inflectional structure in "tongues" if different sounds have harmonic, resonant andor spiritual meanings?

Hey there.... Three easy problems, GL.


1)
How can you measure 6 litres of water using only 4 and 9-litre bowls.


2)
A table tennis ball fell into a tight deep pipe. The pipe was only a bit wider then the ball, so you can not use your hand. How would you take it out, with no damage?


3)
A man lives on the tenth floor of a building. Every morning he takes the elevator down to the lobby and leaves the building. In the evening, he gets into the elevator, and, if there is someone else in the elevator - or if it was raining that day - he goes back to his floor directly. Otherwise, he goes to the seventh floor and walks up three flights of stairs to his apartment. Why this man acts like that?

surely it should be moving away or to the earth. seems unlikely that the speed, mass and gravitational forces are so well balanced? or is it the case that at an orbit at a particular distance from the earth all of these variables cause it to self correct?

On the one hand, we're a lot smarter. On the other, dinosaurs are a lot bigger and stronger. If history had somehow played out differently, and humans had been able to evolve (or be created, your choice) at the same time dinosaurs lived, would we be able to survive? Now there's little doubt that humans today could easily wipe out the dinosaurs, but what about early man? All he had was his brain, and maybe a stick...

What would one of those cost me? Where would I get it?

It's for passive solar water heating. The idea is to put it upstream of the combi boiler, and heat it either directly or with a coil from the solar water heater. The combi boiler runs at mains pressure of course.

How do I arrange things to that the hot water gets to expand when it gets hot?

Is there anything else wrong with this that will make something explode or otherwise embarrass me?
