It is visible to the naked eye in the night sky and can occasionally be seen in the daytime when the Sun is low.

Although it is relatively close to the Sun at just 12 light years, this star cannot be seen with the naked eye.

The supernova was visible to the naked eye for about two years after its first observation.

These schemes, which were based on geometry rather than the arithmetic of the Babylonians, would eventually eclipse the Babylonians' theories in complexity and comprehensiveness, and account for most of the astronomical movements observed from Earth with the naked eye.

Because if you look at a brain with your naked eye, you don't really see how complex it is, but when you use a microscope, finally the hidden complexity is revealed.

Ultraviolet light may also be used to search body surfaces for any evidence not easily visible to the naked eye.

However, a few differences are notable.

Classical physics explains matter and energy on a scale familiar to human experience, including the behaviour of astronomical bodies.

However, occasionally a comet may brighten to naked eye visibility, and even more rarely it may become as bright as or brighter than the brightest stars.

Willard Wigan tells the story of how a difficult and lonely childhood drove him to discover his unique ability to create art so tiny that it can't be seen with the naked eye. His slideshow of figures, as seen through a microscope, can only be described as mind boggling.

Objects cannot be created from abstract data types they can only be derived from.

He was suffering from brain seizures that were impossible to see with the naked eye, but that were actually causing symptoms that mimicked those of autism.

And so, here are four different rhinoviruses, and you can see, even with your eye, without any fancy computer pattern matching recognition software algorithms, that you can distinguish each one of these barcodes from each other.

So let's start off looking at something rather not so small, something that we can see with our naked eye, and that's a bee. So when you look at this bee, it's about this size here, it's about a centimeter.

The first way is that they're actually able to resolve small detail in the context of clutter, and though that means being able to read the fine print on a prescription rather than using magnifier glasses, you can actually do it with just your eyesight.

Causes The vast majority of comets are never bright enough to be seen by the naked eye, and generally pass through the inner Solar System unseen by anyone except astronomers.

Progress today in anatomy is centered in the development, evolution, and function of anatomical features, as the macroscopic aspects of human anatomy have largely been catalogued.

The cause effect correlations are hard to measure, and observable changes are often delayed.

The abstract data models defined in IEC 61850 can be mapped to a number of protocols.

Couple of things to note about that movie. Every piece of equipment that you saw in there did not exist before 1999.

Heat is transferred by conduction when adjacent atoms or molecules collide, or as several electrons move backwards and forwards from atom to atom in a disorganized way so as not to form a macroscopic electric current, or as phonons collide and scatter.

You have to explain what you're doing and how the developmental events of a tadpole are, of course, very observable and they use the same T3 mediated hormones that we do.

Historical architecture Historic architecture can be seen almost everywhere in Al Wakrah and especially in its old areas and it is captured in mosques, old homes and harbour.

It went by relatively unnoticed in July.

Not that that is particularly beautiful when you look at it with the human eye, the way the leaves form. They're curling back on each other.

One winking with the eye causes sorrow, but a chattering fool will fall.

He that winketh with the eye causeth sorrow but a prating fool shall fall.

With at least a hundred billion galaxies in the observable Universe and two hundred billion stars in Earth's Milky Way alone, the potential for planets with the conditions to support human like life is considerate.

The impact of that work was not always immediately evident, but the aim was precisely to obtain sustainable long term results.

There aren't neat examples, but one example is this the way the world is changing is embodied in what's going on at the place I used to work the U.N. Security Council.

Modern Turkish influence remained strong until the Arabic language became the new official language in the 1930s, and a degree of Turkmen Turkish diglossia is still observable.

Abstract problems Abstract mathematical problems arise in all fields of mathematics.

The comet became visible to the naked eye, but was definitely unspectacular.

First, there is the old law of an eye for an eye, a tooth for a tooth.

Children may be held down, may have several adults lie on top of them, or their faces may be held so they can be forced to engage in prolonged eye contact.
