Sommers' proof that something exists
1. Something is possible. 2. Whatever is not a categorially possible thing is not a possible thing. 3. Suppose there were nothing (i.e., nothing exists). 4. By definition D-things are categorially impossible if and only if nothing is D and nothing is D. 5. For any D, nothing is D and nothing is D. (by 3) 6. For any D, D-things are categorially impossible, (by 4 and 5) 7. For any D, D-things are...
متن کاملProof That Chronic Lyme Disease Exists
The evidence continues to mount that Chronic Lyme Disease (CLD) exists and must be addressed by the medical community if solutions are to be found. Four National Institutes of Health (NIH) trials validated the existence and severity of CLD. Despite the evidence, there are physicians who continue to deny the existence and severity of CLD, which can hinder efforts to find a solution. Recognizing ...
متن کاملThe Lorenz Attractor Exists – An Auto-Validated Proof
We present an algorithm for computing rigorous solutions to a large class of ordinary differential equations. The main algorithm is based on a partitioning process and the use of interval arithmetic with directed rounding. As an application, we prove that the Lorenz equations support a strange attractor, as conjectured by Edward Lorenz in 1963. This conjecture was recently listed by Steven Smal...
متن کاملThe Proof That N
is similar to the proof of Theorem 2.4 ((rst direction), together with the second part of Lemma 4.3 that guarantees that D 1 (e) = D 1 (e f) D 1 (e g). Using the last two theorems, we get Let us now brieey discuss the case of computing general relations and not necessarily functions. The equality in Lemma 4.3 part (1), does not hold anymore. However, by FKN91] the two sides cannot be too far. A...
متن کاملAn Estimate of the Odds Ratio That Always Exists
This article proposes an estimate of the odds ratio in a (2 £ 2) table obtained from studies in which the row totals are xed by design, such as a phase II clinical trial. Our estimate,basedon themedianunbiasedestimateof the probabilitiesof success in the (2£2) table, will always be in the interval (0;1): Another estimate of the odds ratio which has such properties is obtained when adding .5 t...
