This importance lessened with the development of the radio and the telegraph , but even today, when flying an aircraft under visual flight rules , a technique called attitude flying is used to control the aircraft, where the pilot uses the visual relationship between the aircraft's nose and the horizon to control the aircraft.

A pilot can also retain his or her spatial orientation by referring to the horizon. In many contexts, especially perspective drawing, the curvature of the Earth is disregarded and the horizon is considered the theoretical line to which points on any horizontal plane converge when projected onto the picture plane as their distance from the observer increases.

For observers near sea level the difference between this geometrical horizon which assumes a perfectly flat, infinite ground plane and the true horizon which assumes a spherical Earth surface is imperceptible to the unaided eye [ dubious — discuss ] but for someone on a meter hill looking out to sea the true horizon will be about a degree below a horizontal line.

In astronomy, the horizon is the horizontal plane through the eyes of the observer. It is the fundamental plane of the horizontal coordinate system , the locus of points that have an altitude of zero degrees.

While similar in ways to the geometrical horizon, in this context a horizon may be considered to be a plane in space, rather than a line on a picture plane.

Ignoring the effect of atmospheric refraction , distance to the true horizon from an observer close to the Earth's surface is about [2]. When d is measured in miles statute miles i.

On terrestrial planets and other solid celestial bodies with negligible atmospheric effects, the distance to the horizon for a "standard observer" varies as the square root of the planet's radius.

If the Earth is assumed to be a featureless sphere rather than an oblate spheroid with no atmospheric refraction, then the distance to the horizon can easily be calculated.

The secant-tangent theorem states that. The same equation can also be derived using the Pythagorean theorem. At the horizon, the line of sight is a tangent to the Earth and is also perpendicular to Earth's radius.

This sets up a right triangle, with the sum of the radius and the height as the hypotenuse. Using imperial units , with d and R in statute miles as commonly used on land , and h in feet, the distance to the horizon is.

If d is in nautical miles , and h in feet, the constant factor is about 1. If h is significant with respect to R , as with most satellites , then the approximation is no longer valid, and the exact formula is required.

The distance s can also be expressed in terms of the line-of-sight distance d ; from the second figure at the right,. To compute the greatest distance at which an observer can see the top of an object above the horizon, compute the distance to the horizon for a hypothetical observer on top of that object, and add it to the real observer's distance to the horizon.

For example, for an observer with a height of 1. Thus an observer on a beach can see the top of the tower as long as it is not more than Referring to the figure at the right, the top of the lighthouse will be visible to a lookout in a crow's nest at the top of a mast of the boat if.

As another example, suppose an observer, whose eyes are two metres above the level ground, uses binoculars to look at a distant building which he knows to consist of thirty storeys , each 3.

He counts the storeys he can see, and finds there are only ten. So twenty storeys or 70 metres of the building are hidden from him by the curvature of the Earth.

From this, he can calculate his distance from the building:. It is similarly possible to calculate how much of a distant object is visible above the horizon.

His horizon is:. The ship is a further 8. The height of a point on the ship that is just visible to the observer is given by:.

The observer can therefore see that part of the ship that is more than six metres above the level of the water. The part of the ship that is below this height is hidden from him by the curvature of the Earth.

In this situation, the ship is said to be hull-down. Due to atmospheric refraction the distance to the visible horizon is further than the distance based on a simple geometric calculation.

If the ground or water surface is colder than the air above it, a cold, dense layer of air forms close to the surface, causing light to be refracted downward as it travels, and therefore, to some extent, to go around the curvature of the Earth.

The reverse happens if the ground is hotter than the air above it, as often happens in deserts, producing mirages.

If the Earth were an airless world like the Moon, the above calculations would be accurate. However, Earth has an atmosphere of air , whose density and refractive index vary considerably depending on the temperature and pressure.

This makes the air refract light to varying extents, affecting the appearance of the horizon. Usually, the density of the air just above the surface of the Earth is greater than its density at greater altitudes.

This makes its refractive index greater near the surface than at higher altitudes, which causes light that is travelling roughly horizontally to be refracted downward.

This changes the factor of 3. This correction can be, and often is, applied as a fairly good approximation when atmospheric conditions are close to standard.

When conditions are unusual, this approximation fails. Refraction is strongly affected by temperature gradients, which can vary considerably from day to day, especially over water.

In extreme cases, usually in springtime, when warm air overlies cold water, refraction can allow light to follow the Earth's surface for hundreds of kilometres.

Opposite conditions occur, for example, in deserts, where the surface is very hot, so hot, low-density air is below cooler air.

This causes light to be refracted upward, causing mirage effects that make the concept of the horizon somewhat meaningless. Calculated values for the effects of refraction under unusual conditions are therefore only approximate.

Outside the visual wavelength range, refraction will be different. For radar e. If the density profile of the atmosphere is known, the distance d to the horizon is given by [8].

The dip is determined fairly simply from. The distance to the horizon is then [2]. Results from Young's method are quite close to those from Sweer's method, and are sufficiently accurate for many purposes.

From a point above Earth's surface, the horizon appears slightly convex ; it is a circular arc. The curvature is the reciprocal of the curvature angular radius in radians.

A curvature of 1. However, the apparent curvature is less than that due to refraction of light by the atmosphere and the obscuration of the horizon by high cloud layers that reduce the altitude above the visual surface.

The horizon is a key feature of the picture plane in the science of graphical perspective.

While mechanical meta-materials have been studied for a while now, especially auxetic mechanical metamaterials, special combinations of metamaterials are rarely explored.

This study highlights the effectiveness of creating hybrid meta-biomaterials, which can be designed to exhibit specific mechanical properties such as a hybrid Poisson's ratio.

It therefore demonstrates a proof-of-concept of applying rational design and meta-biomaterials to improve implant longevity.

The significance of combining specific mechanical metamaterials has been proven, and with the recent advances in additive manufacturing this opens up an interesting field of research.

We demonstrate a new machine learning-based design approach for hierarchical materials. The new designs created by our machine learning model, which is trained with a database of hundreds of thousands of geometries from finite element analysis, are validated using additive manufacturing and experimentation.

Whereas most of the previous work applying machine learning in materials science is solely focused on predicting material properties, we aim to go beyond property prediction to optimize specific properties.

This is achieved by further augmenting a convolutional neural network model with our self-learning algorithm; the goal being to learn patterns from sampled top-performing geometries to create even better designs, phasing out inferior designs for superior candidates.

The result is a suite of new designs that outperform the training set. Additionally, for the first time in literature, we show that machine learning can be used as an alternative method for coarse-graining — analyzing and designing materials without the use of full microstructural data.

The coarse-graining is realized by condensing a collection of building blocks into a single unit cell — significantly reducing the number of parameters needed in our machine learning model.

Thus, this new approach accelerates the search for high-performing hierarchical materials by orders of magnitude and is widely applicable to other material systems to optimize a variety of properties.

Unexpected surface interactions between fluorocarbons and hybrid organic inorganic perovskites evidenced by PM-IRRAS and their application towards tuning the surface potential.

We pioneer the use of a surface-specific IR spectroscopy technique to probe how molecules deposit on the surface of hybrid organic—inorganic perovskites.

Although surface passivation can considerably improve their performance, there is as yet little understanding on how molecules interact with the ionic crystal due to the lack of suitable experimental techniques.

We show that PM-IRRAS can be adapted to work on perovskites to provide information on the density and orientation of molecules on the surface as well as the chemical nature of the molecules, in much the same way as IR spectroscopy can be used to identify molecules in solution or in the solid state.

Thanks to this technique, we were able to evidence the spontaneous formation of ordered monolayers of even simple fluorocarbons onto the perovskite surface.

This surprising result evidences the existence of interactions between fluorine atoms and the hydrophilic surface.

We further show that it is possible to harness these interactions to tune the surface potential of the material over a mV range through the formation of a single monolayer.
