He willingly accepted the strange nature of light and chose whichever attribute best addressed the problem he was trying to solve. Today, physicists accept the dual nature of light. In this modern view, they define light as a collection of one or more photons propagating through space as ...
This useful fact allowed chemists to compare the relative weights of equal volumes of different gases to determine the relative masses of the atoms composing them. They measured atomic weights in terms of atomic mass units (amu), where 1 amu was equal to one-twelfth of the mass of a carbon...
The initial dissolution peak of Cu suggests that Cu-rich particles on the surface start to detach and dis- solve first23. The dissolution behavior of solutes in the peak-aged, under-aged, and over-aged alloys is similar, except that less dissolution of Mg and Zn is observed for the over...
Chemistry is a broad and dynamic field that touches nearly every aspect of science and industry. From environmental sustainability to medical advancements, chemistry research fuels discoveries that solve real-world challenges. Choosing the right chemistry research topic can be overwhelming, with many fasci...
How to solve for partial pressure? A gas exerts a pressure of 660 atmospheres (atm). What is this pressure in Torr (mmHg)? A pressure of 2.5 atm is equivalent to: a. 41 kPa b. 1900 mm Hg c. 3.0 x 10^2 mm Hg d. 2.5 kPa ...
How to calculate relative molecular mass of a gas? What happens to the kinetic energy of a molecule when a gas is heated? For an ideal gas, why is it assumed that individual molecular volume and intermolecular forces are negligible?
, all possible consequences. The advent of computers, and their availability to the scientific community in the 1940s, opened novel perspectives: numerically solve the equations of statistical mechanics. These laws typically require calculation of averages of suitable microscopic observables over ...

1a and 4a, but not used in atomic model building or refinement. CryoSparc 3D Variability Analysis was performed for the focused GR:FKBP51 and GR:FKBP52 reconstructions with the following parameters: number of modes to solve, 3; symmetry, C1; filter resolution, 6 Å; filter order, 1.5;...
How to solve an "atomic vector" problem when getting data through an API ? yfit <- yfit*diff(h$mids[1:2])*length(x) Is there an R package that easily identifies an observation that best "represents" the model?" How do I add the values of a Table Shares Oustanding using ...
