Objective Certainty: How Can We Know?

AI Thread Summary
The discussion centers on the concept of objective certainty and whether it can be achieved. A character from the show Numb3rs claims varying levels of certainty based on data analysis, prompting questions about the validity of such claims. Participants suggest that true objective certainty is difficult to attain and may rely more on subjective interpretation. Bayesian analysis is mentioned as a method for quantifying certainty based on data, highlighting the complexity of establishing absolute certainty. Ultimately, the conversation reflects skepticism about the existence of objective certainty in knowledge and decision-making.

Hey guys, I'll get straight to the point

Today I was watching a television show in which a character said "from he data I analyzed, I'm 86% sure that I'm right" but when new data was revealed to the character, he says "Now I'm 92% certain that I'm right". The character doesn't show how he arrived at these numbers, and that's why I'm here: Is it possible to be objectively certain about something? If so, how?

I'm anticipating the character was just going by intuition and just made up numbers, but I just think it's unlikely that's that case...the Show btw is Numb3rs.

I think it comes down to a matter of opinion and semantics; but it would be pretty hard to argue that there is an absolute, objective certainty about anything (certainly Descartes wouldn't think so).
The way one would come about numbers like that would be through a Bayesian analysis of the data and the theory he's comparing them to. see: http://en.wikipedia.org/wiki/Bayesian_statistics

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
