First commandment

God gave Moses ten very important rules to live by, called the commandments.

The first one is:
Thou shalt have no other gods.
(from: wikisource - Luther's Small Catechism)

This means we should make God the most important thing in our lives, above anything else.

ENIAC


The first computer was called the ENIAC.
(Sounds like Any-Ack) It stands for a bunch of big words that just mean it was a big math calculator:
Electronic Numerical Integrator And Computer

It wasn't like any of the fancy computers we have now with big colored touch screens!
It was a whole room full of wires and lights and could only do math problems with numbers.
This might not seem like much, but it could figure out over 350 problems like this in less than a second.
Way faster than most humans!

Electrical Box


The electricity for your light bulbs, comes from wires in the ceiling and walls.

(From: Wikipedia - electrical wiring)

Those wires go through the walls and end up in something called an electrical box, or breaker box.
In many homes it's found in the basement.
All the wires go into the electrical box, and there are switches like a light switch that can turn the electricity off for the whole house!

The electricity comes into the electrical box from big wires that that go all the way back to the power company.

If this is hard to remember, you can try to remember that they connect your vertebrae in back to your sternum in front.
Vertebrae + sternum = Vertebrosternal
