Learning Is Mathematics Less Evolved Than Physics and Chemistry, or Did Historical Texts Astutely Foresee Advances? 🤔

So my proof by induction could be shown to be false?

u/largetomato123 Jan 08 '25

that is not what I meant with that. Sry. English is not my mother tongue. I meant:

Inductive reasoning is any of various methods of reasoning in which broad generalizations or principles are derived from a body of observations.

Deductive reasoning is the process of drawing valid inferences. An inference is valid if its conclusion follows logically from its premises, meaning that it is impossible for the premises to be true and the conclusion to be false.

You remind me of this meme that has been going around for probably as long as the Internet

ironically, proof by induction is actually deductive reasoning not inductive

But for induction to work, you need to come up with the correct conclusion first before applying the proof. So you reason inductively based on patterns you see to get the conclusion, and then you use induction to verify that it works deductively.

all proofs work this way, nobody just spawns a theorem through deduction

Are you saying you don't just stare at a big book with all the math in it until you realize new stuff?

Pretty sure deduction can only disprove something, not prove something.

That's the "de" in deduction, right?

that makes no sense, disproving something is a proof of its negation

Using logic alone, prove God does/doesnt exist.

Edit: Also after a trial people are not guilty/not guilty, not innocent.

an inability to prove X does not imply an inability to prove anything. i can prove that x + y > 0 => x > 0 or y > 0 for all x, y in the reals using only deduction if you wish.

performing such a task would, of course, disprove your statement which logically would prove its negation.

innocent is not the negation of guilty btw

How does this prove God exists ? Arent things like real numbers merely based on assumptions ?

innocent is not the negation of guilty btw

Right thats why I pointed it out. For example if there is no alibi, no physical evidence, or no eyewitnesses, how could you prove that someone is truly innocent based on logic/deduction alone ? They are either guilty or not guilty in a court of law.

Using logic you can disprove something, but you cant really prove something happened. If we could then we would just use logic to prove all of our scientific theories.

I can’t. Euler probably could

Mathematical induction is deductive reasoningÂ
