Hi ~ I'm just starting to learn electronics. The book that came with my 300 in 1 kit says that, when looking at the flat side of a transistor, the legs are emitter, COLLECTOR, base from left to right, but every other website and starter guide shows them as emitter BASE collector. The circuits in the 300 in 1 seem designed to work based on the ecb configuration. I'm kinda confused. These transistorsistors are PNP and NPN if that makes any difference. Thanks for your help

... what’s the deal with our good friend, the nautilus? More than 500 million years has passed over it without essentially any evolutionary effects, whatsoever!!! ... Is the nautilus such a perfect experiment in evolutionary design that it hasn’t required Nature's tweaking in all this time?

I find this topic very interesting. SecondStar have already asked a question using kamikaze techniques. Instead of that, why not we build a tower that extends until it breaks the gravity. It will need a large base to support the weight but overall this is the most safest idea.

Then simply loading these wastes in capsules and launch it into space towards the sun.

So what do you guys think?

How did water get here? Comets are mostly water - could collisions with comets have delivered water (and life?) to earth.

Also, do we lose water through the atmosphere?
