Julius Lothar Meyer (19 August 1830 – 11 April 1895) was a German chemist. He was one of the pioneers in developing the earliest versions of the periodic table of the chemical elements . The Russian chemist Dmitri Mendeleev (his chief rival) and he had both worked with Robert Bunsen .

Lothar Meyer later wrote that on reading Cannizzaro's paper, [11] [12] I was astonished at its clarity, the little manuscript covered all the important points in dispute. It was as if scales fell from my eyes, doubts vanished, and a feeling of calm certainty came over me.
1869: Dmitri Ivanovich Mendeleyev published his periodic table of chemical elements, and the following year (1870) Julius Lothar Meyer published his independently constructed version. 1873: Bolesław Prus propounded a "law of combination" describing the making of discoveries and inventions : "Any new discovery or invention is a combination of ...
The bathtub curve is a particular shape of a failure rate graph. This graph is used in reliability engineering and deterioration modeling. The 'bathtub' refers to the shape of a line that curves up at both ends, similar in shape to a bathtub. The bathtub curve has 3 regions: The first region has a decreasing failure rate due to early failures.
The medal has been awarded to multiple individuals in the same year: in 1882, for example, it was awarded to Dmitri Mendeleev and Julius Lothar Meyer "for their discovery of the periodic relations of the atomic weights"; [6] in 1883 to Marcellin Berthelot and Julius Thomsen "for their researches in thermo-chemistry"; [6] in 1893 to Jacobus ...
An important advantage of the Kaplan–Meier curve is that the method can take into account some types of censored data, particularly right-censoring, which occurs if a patient withdraws from a study, is lost to follow-up, or is alive without event occurrence at last follow-up. On the plot, small vertical tick-marks state individual patients ...
The intersections of this curve and the 45° line are points that satisfy equation (3-4), so the intersections represent fixed points and 2-periodic points. If we draw a graph of the logistic map f 2 ( x ) {\displaystyle f^{2}(x)} , we can observe that the slope of the tangent at the fixed point x f 2 {\displaystyle x_{f2}} exceeds 1 at the ...
