  • 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.















  • Denying entry for people in need can’t be the answer. Honestly, it’s unfair that we were lucky enough to be born into a stable country. It’s unfair that other people have to live under dictators looking only for their personal interest. It’s unfair that people have to live under the consequences of global power struggles and it’s also unfair that Western countries exploit other nations and then don’t lend assistance when everything turns to shit.

    How can you justify sending away these people that are fleeing from warzones or due to global warming. They are losing family and their homes and yet, they spent their life worrying while we can go to restaurants, cafes, play in parks, go hiking, swimming or biking without ever having to worry.

    Leaning into the immigration policy of the right cannot be the answer, there has to be another solution.
