Self-monitored, home-based pulmonary rehab was non-inferior to outpatient, hospital-based rehab for COPD.

Patients: 252 patients ≥ 40 years of age (mean age 66 y, 56% men) who had stable COPD (no change in medication or symptoms for ≥ 4 wk), were current or former smokers of ≥ 10 pack-years, had an FEV1 < 70% of predicted value and FEV1–FVC ratio < 0.70, and had a Medical Research Council (MRC) dyspnea score ≥ 2. Exclusion criteria included history of asthma, congestive left heart failure as primar...

Why was Relativity Accepted?

Historians of science have published many studies of the reception of Einstein’s special and general theories of relativity. Based on a review of these studies, and my own research on the role of the light-bending prediction in the reception of general relativity, I discuss the role of three kinds of reasons for accepting relativity: (1) empirical predictions and explanations; (2) social-psycho...

Was Einstein 100% Right ? *

The confrontation between General Relativity and experimental results, notably binary pulsar data, is summarized and its significance discussed. The agreement between experiment and theory is numerically very impressive. However, some recent theoretical findings (existence of non-perturbative strong-field effects, natural cosmological attraction toward zero scalar couplings) suggest that the pr...
