In simple terms, it’s where the solar wind—the hot ionized gas emitted by the Sun—breaks free of the Sun and shoots out into space. But to understand how cool this is, we need to dig a bit deeper. After all, how can we say where the solar wind “breaks free of the Sun”?
The boom in the wind power industry is showing no sign of stopping. All around the world, renewable energies are a popular investment vehicle and wind turbines are playing an increasingly important role. Accordingly, the demand for drives for building wind turbines is also growing. This is a ...
The work will be mainly related to quantum feedback of superconducting qubits. The first experiment waspublished inNaturetoday. (Some News & Views discussion can be seenhere.) The theory is still rather simple and needs improvement. 1 Comment| ...
In outline terms the mechanical system of a podded propulsor has normally comprised a short propulsion shaft on which an electric motor is mounted and supported on a system of rolling element radial and thrust bearings. Some contemplation within the industry is being given to changing from rolling...

Specifying the viewpoint in terms of azimuth and elevation is conceptually simple, but it has limitations. It does not allow you to specify the actual position of the viewpoint, just its direction, and thez-axis is always pointing up. It does not allow you to zoom in and out on the sc...

However, as we keep introducing new features in StockFlow.jl, it takes time to implement them in ModelCollab. But what’s a stock-flow diagram, and what does our software let you do with them? The picture here shows an example: a simple disease model where Susceptible people become ...
Directional drilling is widely utilized today for the efficient exploitation of oil and gas fields, but requires great accuracy in drill orientation as to both azimuth and inclination or drift angle. Straight sections of the bore are drilled with a simple rotary drill, and required alterations in...
