Rob mentioned the proposal for a tether from Mars-Phobos Lagrange to Phobos, and noted it was interesting but had no advantage over conventional rockets. But it got him thinking about Phobos. Back of the envelope calculations suggested that if Phobos was a mix of water ice and the same mater...

Value semantics. Meaning that the queues make a copy/move uponpush/pop, no reference/pointer to elements in the queue can be obtained. The impact of each of these small design choices on their own is barely measurable, but their total impact is much greater than a simple sum of the const...
It requires extremely high densities and pressures to force the nuclei of elements like hydrogen and helium to overcome their natural inclination to repel each other. On Earth, fusion experiments typically require large, expensive equipment to pull off. But researchers at NASA’s Glenn Research ...
To achieve atomically sharp edges with well-defined terminations, the flake that was pre-patterned in step (ii) was further exposed to an aqueous solution of H2O2 and NH4OH (1:1:10 H2O2:NH4OH:H2O volume ratio of stock solutions) at mild heating (T = 50 °C) in step (iii). ...
When the inclusion of an additional Gaussian no longer significantly improves the log likelihood and linearity of the QQ plot, the GMM is assumed to be optimal. The final GMM can be expressed in tabular form (Table 1) or graphical form (Fig. 1). Table 1 Fitted Gaussian Mixture Models ...
Atomic and close-to-atomic scale manufacturing provides a fundamental competence for the production of the fourth generation of core elements in contemporary industrialization. This review is organized based on atomic-level operation modes in subtractive, additive and transformative manufacturing processes....
Global elements: components like headers, footers, and other global elements that are shared across the entire experience. Navigation: primary navigation, footer navigation, pagination, breadcrumbs, interactive component controls, and essentially anything that’s used to navigate around a user interface. ...
4. There is no net charge on the atom as positive and negative charges cancel out each other.Fig. 6. The proposed structure of the nuclear atom by Ernest Rutherford.Henry Moseley’s contribution to the atomic structure ~ 1913Before Mosley, the atomic number of elements was an arbitrary ...
