If you only care about adding numbers, you can e.g. do that using water or marbles. You only need to build an XOR gate, an AND gate and an OR gate.

In case of water, the gate will have two inputs as water streams. They should be aligned so that when the streams hit each other, the water will flow into a cup in the center of the apparatus. When the streams don't hit each other, the water passes the first cup and flows into another cup on the bottom. Carrying the water out at the bottom is the XOR gate, carrying the water out at the center is the AND gate and both cups together are the OR gate.

Then it's just about setting up the circuit and that would be a full adder without electronics.

It's really useful for programming. It's not always right but it has good approaches and you can ask it to write tedious parts of your code like long switch statements. Most of my programming problems were solved because I just explained the problem like Rubber Duck Debugging.

You can't pin that on the voter because not voting for the democrats is effectively voting for the republicans. It's a problem of the two party system

You got it pretty much on point. Shooting a laser at atoms is like shooting a machine gun at an indestructible target. If it moves towards you, you can slow it down. But preventing it from accelerating when the target is stationary is where quantum mechanics comes in. That is your explanation: The laser light only acts as a force when the light is resonant with the atom and the Doppler effect means that the resonance condition changes depending on the speed of the atoms.

Adding to what DmMacniel said, it's a hardware interface, often accessed via a USB port (which after all, is the universal serial bus).

Mozilla has been building gecko for decades, why would they cave to a conglomerate and invalidate their principles?
