Can someone walk me through an example of first principles thinking?,(reply>), @Marko This made it A LOT more clear for me, especially the part where you said you question assumptions until you reach something that breaks the laws of physics,(reply>), @ABC CDE Thank you!,(reply>), Analogous thinking: it is impossible to colonize Mars because it is too expensive, unreliable, too far away for our technology, gravity on the Earth is too strong.<br><br>First principle thinking:<br>It is expensive because you build rockets from scratch every time you fly. If we make it reuseable in this and that way, we can lower the cost and make it viable.<br><br>Unreliable is conditioning problem. We can do that with dilegence.<br><br>If a starship takes off from the far away athmosphere it doesnt need to deal with gravity, etc.<br><br>Analogous thinking is saying something is impossible when in fact is merely improbable. First thinking is questioning every such assumption till you get to an actually impossible part. It becomes impossible when laws of  physics are broken. You can not break laws of physics. For example you can not go faster than the speed of light so you cant get to mars in 2 seconds. Thats a fact,(reply>), We want to go to Mars and we need rocket. Lets try to buy rocket from Russia. We travel, probe and figure out that price is blown up and unrealistic. We need to build our own rocket. Spend month studying aerospace industry and physics behind it. Breakdown how much each material cost to make small rocket. its doable, we can udercut price. So here you have it. Instead of using common mind - it hasn't be done before its impossible to execute, you break it down to a what would it take to make it and how.
